具有滑动套筒的静轴卡盘系统 Static axis chuck system with a sliding sleeve

技术领域 FIELD

[0001] 本发明涉及一种将附件连接到动力驱动器上的工具卡盘,特别涉及一种具有卡爪的工具卡盘,该卡盘能由驱动器传输的动力致动。 [0001] The present invention relates to a tool chuck attachment is connected to the power drive, and more particularly to a tool having a jaw chuck, the chuck can be actuated by a power drive transmission.

背景技术 BACKGROUND

[0002] 本申请要求在2005年8月31日提交的第60/712,403号美国临时专利申请的优先权,兹将该申请所公开的全部内容结合到本文中以作参考。 [0002] This application claims the No. 60 / 712,403 filed US Provisional Patent Application 31 August 2005 submitted the application to the entire contents of the disclosure is hereby incorporated herein by reference.

[0003] 将2005年4月19日提交的第60/672,503号('503申请),名称为“T00LCHUCKWITH POWER TAKE OFF AND DEAD SPINDLE FEATURES”的美国申请,结合到本文中以作参考。 [0003] The 672,503 No. 19 April 2005 No. 60 / ('503 application), entitled "T00LCHUCKWITH POWER TAKE OFF AND DEAD SPINDLE FEATURES" US application, which is incorporated herein by reference. '503申请通过示例介绍了在不同的模式其中包括卡固模式下可选择地运行的动力驱动器。 '503 application powered by example presented in different modes, including under selectively retaining mode operation. 在卡固模式下,启动驱动器继而运行(如打开和关闭)工具卡盘。 In the clamp mode, the boot drive and then run (such as opening and closing) tool chuck. 卡固过程中,卡盘体和卡爪不旋转。 Retaining process, chuck body and jaw does not rotate. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就称为所谓“静轴”特征。 Because the user is not likely to be affected (or observed) any rotating parts, which is a so-called "static axis" feature.

[0004] 工具卡盘供有滑动套筒,滑动套筒可被选择地安装(即旋转固定)在动力驱动器的机壳上。 [0004] The tool chuck is supplied with the sliding sleeve, the sliding sleeve may be selectively mounted (i.e., rotationally fixed) of the power drive of the cabinet. 当套筒安装完毕,驱动器启动直到致动工具卡盘。 When the sleeve is installed, the drive starts until actuated tool chuck. 在一些情况下,套筒可选择地将卡盘体安装在动力驱动器的机壳上。 In some cases, the sleeve chuck body selectively installed on the power of the drive housing. 这里,在卡盘致动过程中,卡盘体和卡爪不发生旋转,从而影响静轴特征。 Here, in the chuck actuation process, chuck body and claws do not rotate, thus affecting the static axle features.

[0005] 传统的滑动套筒工具卡盘通常认为能提供可以达到的性能。 [0005] The conventional sliding sleeve tool chuck is generally believed to provide performance can be achieved. 然而,如果卡盘体是可选择地安装在动力驱动器的机壳上,同时电机向前运转直到卡爪紧固到附件上,那么此时就会导致电机停转。 However, if the chuck body is optionally installed on the power drive chassis, while the motor is running forward until the jaws fastened to the accessory, then the time will cause the motor to stall. 当工具卡盘被驱动至达到完全打开的状态时,电机也有可能停转。 When the tool chuck is driven to its fully open state, the motor may also be stopped. 电机停转有可能毁坏电机,破坏传输和/或造成紧固转矩的不稳定。 Motor stops may damage the motor, transmission damage and / or destabilizing tightening torque.

[0006] 为了克服上述缺点作了大量工作。 [0006] In order to overcome these shortcomings made a lot of work. 例如,动力驱动器可配有电动离合器。 For example, the power drive can be equipped with an electric clutch. 这里,当滑动套筒可选择地与动力驱动器的机壳接合时,电动离合器能将其施加的转矩限制在一个期望的紧固转矩(在卡固启动过程中)范围内。 Here, when the sliding sleeve is selectively engaged with the driving force of the drive housing, the electric clutch torque which can be applied is limited to a desired tightening torque (in the clamp startup) range. 或者,通常用在钻孔/驱动模式下以限制施加的转矩的动力驱动器的机械式离合器,也可应用以将施加的转矩限制在一个期望的紧固转矩(在卡固启动过程中)范围内。 Alternatively, commonly used in drill / driving mode to power the drive torque limitations imposed by the mechanical clutch, can also be used to limit the torque applied in a desired tightening torque (in the clamp startup ) within range.

[0007] 上面所述的电动和机械式离合器都并非没有缺点。 [0007] The above electric and mechanical clutches are not without drawbacks. 比如,动力驱动器需要配备多重操作速度。 For example, the power drive requires multiple operations with speed. 如果电子设备不能确定和校正所选的操作速度,那么电子离合器传送的转矩在卡盘启动过程中就会改变。 If the electronic device can not be identified and corrected the selected operating speed, the electronic clutch torque transmitted chuck boot process will change. 当动力驱动器的机械式离合器用作卡盘启动过程中限制施加的转矩在一个期望的紧固转矩时,也会出现同样的状况。 When used as a clutch torque mechanical power chuck startup drive limit imposed when an expected tightening torque, there will be the same situation.

[0034] 锤击机构70包括旋转棘齿72、旋转固定棘齿74和凸轮环76。 [0034] The hammer 70 includes a rotation ratchet mechanism 72, rotation of the ratchet teeth 74 and the fixed cam ring 76. 如图I所示,旋转棘齿72和输入轴10可为一个整体即一体结构。 Figure I shows, the rotating ratchet teeth 72 and the input shaft 10 may be a unitary structure that is integral. 在可替换的实施例中,旋转棘齿72和输入轴10为两个可被固定在一起的分离和不同的部件。 In an alternative embodiment, the rotary ratchet teeth 72 and the input shaft 10 as two separate and different components may be secured together. 旋转固定棘齿74相对于机壳90的主体92旋转地固定并可轴向运动。 Ratchet teeth 74 rotationally fixed relative to the housing 90 of the body 92 is rotatably fixed and axially movement. 旋转固定棘轮74具有中心孔,输入轴10可通过该孔延伸。 Rotationally fixed ratchet 74 has a central bore, the input shaft 10 may extend through the aperture. 凸轮环76包括使用者可操作的控制杆或套筒,以可选择地将棘轮72、74接合。 Cam ring 76 includes a user operable lever or sleeve, 72, 74 to selectively engage the ratchet.

[0035] 弹簧6设置在旋转、固定棘轮74和输入轴10的凸缘14之间。 [0035] The spring 6 is disposed between the flange rotation, the ratchet wheel 74 fixed to the input shaft 10 and 14. 弹簧6可影响旋转固定棘轮74轴向向前的运动以及与凸轮环76的操作接合。 Spring 6 may affect rotationally fixed axial forward movement of the ratchet wheel 74 and the cam ring 76 in operative engagement. 旋转固定棘轮74的轴向向后的运动受到凸轮环76的限制。 Axially rearward movement of the ratchet wheel 74 is rotatably secured by the cam ring 76 limits. 弹簧6也会影响输入轴10 (并因此影响可旋转棘轮72)的轴向前向的运动。 Spring 6 also affects the input shaft 10 (and thus affect the rotatable ratchet 72) in the axial direction of movement. 输入轴10的轴向前向的运动受到连接部20的限制。 Before entering the axial movement of the shaft 10 is restricted to the connecting portion 20.

[0036] 销8滑动安装在端盖94圆周周围的各个轴向孔上(图中未示出)。 [0036] pin 8 slidably mounted on each axial bore 94 around the circumference of the end cap (not shown). 销8的前端延伸入端盖94的凹穴98内。 Pin 8 of the front cover 94 extends into the inner recesses 98. [0037] B.操作 [0037] B. Operation

[0038] 工具卡盘50的操作根据以下因素而不同:(I)旋转固定棘轮74的轴向位置;(2)套筒60的轴向位置。 [0038] Operation of the tool chuck 50 varies based on the following factors: (I) the rotational position of the ratchet wheel 74 is fixed axially; axial position (2) of the sleeve 60. 不同的操作模式包括(但并非局限于)钻孔/驱动模式、锤击模式和卡固模式。 Different modes of operation include (but are not limited to) drill / driving mode, the hammer mode and the retaining mode.

[0039] 图1、2所示为卡盘系统无偏压下的钻孔/驱动模式。 [0039] Figure 1 is no drill chuck system / drive mode under bias. 如图所示,旋转固定棘轮74处于轴向向后的位置(且与旋转棘轮72脱离),因此锤击机构70处于停止状态。 As shown, the ratchet wheel 74 is rotationally fixed axial rearward position (and the ratchet wheel 72 from rotating), so the hammer mechanism 70 is in a stopped state. 同时,套筒60位于轴向向前位置。 At the same time, sleeve 60 located in the axial forward position. 在这种情况下,卡盘驱动轴55的花键56 (如图7所示)与套筒60的后向花键66接合,这样卡盘体52、卡盘驱动轴55和套筒60就能够旋转锁定在一起,并且作为一个单元一起旋转。 In this case, the chuck 55 of the spline shaft 56 (Fig. 7) and the rear of the sleeve 60 engages the splines 66, so that the chuck 52, the chuck 55 and the sleeve 60 on the drive shaft rotatably locked together, and rotate together as a unit. 由于卡盘体52和卡盘驱动轴55旋转锁定在一起,工具卡盘50在操作中就不会松动。 Due to chuck 52 and chuck rotating shaft 55 are locked together, the tool chuck 50 will not loosen during operation.

[0040] 然后使用者启动驱动器以旋转驱动输入轴10,使其相对于旋转固定棘轮74旋转。 [0040] The user then starts to drive the rotary drive input shaft 10 to rotate relative to the fixed ratchet wheel 74 rotates. 输入轴10通过驱动凸耳16和从动凸耳26之间的接合来旋转驱动输出轴30。 By driving the input shaft 10 and the driven lugs 16 engaging lugs 26 between the output shaft 30 is rotationally driven. 在弹簧6的作用下,驱动凸耳16的逐渐变细斜面超过从动凸耳26的逐渐变细斜面而插入到连接部20内。 Under the action of spring 6, the drive lug inclined surface 16 tapers more than the driven lug 26 is tapered chamfer 20 is inserted into the connection portion. 这种状态下,将提供转矩联结,在该转矩联结中,输入轴10的所有转矩传输到输出轴30上。 In this state, will provide the torque coupling, the torque coupling, all the torque input shaft 10 is transmitted to the output shaft 30. 输出轴30旋转驱动工具卡盘50。 The output shaft 30 is rotated drive the tool chuck 50.

[0041] 图3、4所示与图1、2所示相似,均为钻孔/驱动模式,不同的是卡盘系统处于偏置状态。 [0041] similar to that shown in Figure 3 and 4 and shown in Figures 1 and 2, are the drill / driving mode, except that the chuck system in a biased state. 比如,当使用者将附件(如钻头)压靠在工件上时,偏压(或者外力)就发生了。 For example, when the user attachments (such as drill bits) pressed against the workpiece, the bias (or force) occurred. 如图所示,偏压会克服输出轴30的凸缘34与轴承4之间的弹簧(图中未示出)的影响,在相对于机壳90的轴向向后的方向上移动工具卡盘50 (并因此移动输出轴30和输入轴10)。 As shown, the bias will be overcome output shaft 30 and the bearing flange 34 a spring (not shown) between the impact of 4, with respect to the axial direction of the housing 90 rearward movement of the tool Cards plate 50 (and thus moving the output shaft 30 and the input shaft 10).

[0042] 输出轴30 (并因此工具卡盘50)的轴向向后运动受到压靠轴承4的凸缘34的限制。 [0042] The output shaft 30 (and thus the tool chuck 50) by an axial rearward movement of the bearing 4 is pressed against the restriction of the flange 34. 这样,由于偏压所致的组件的轴向向后运动就受到了限制,因此旋转棘轮72保持远离旋转固定棘轮74 (也就是锤击机构70保持停止),并且套筒60保持远离端盖94。 Thus, since the axial rearward movement of the component due to the bias has been limited, and therefore the rotation of the ratchet 72 is held away from the ratchet wheel 74 rotationally fixed (i.e., the hammer mechanism 70 is kept stopped), and the sleeve 60 is kept away from the end cap 94 . 当偏压去除后,组件就会回到图1、2所示的状态。 When the bias is removed, the assembly will return to the state shown in Figures 1 and 2.

[0043] 图5、6所示为卡盘系统偏压的锤击模式。 Shown in [0043] Figures 5 and 6 for the chuck system bias hammer mode. 使用者可以操作凸轮环76使旋转固定棘轮74在轴向向前的方向上移动并克服弹簧6的影响以实现锤击模式。 The user can operate the cam ring 76 so that rotation of the ratchet 74 is moved and fixed to overcome the influence of the spring 6 to achieve hammer mode in the axial forward direction. 由于卡盘系统被偏压,输出轴30 (依靠连接部20),在轴向向后的方向上移动输入轴10 (并因此移动旋转棘轮72)和克服弹簧6的影响。 Since the chuck system is biased, the output shaft 30 (by virtue of the connection portion 20), in the axial direction of rearward movement of the input shaft 10 (and thus the rotational movement of the ratchet 72) and overcome the effects of the spring 6. 在这种状态下,旋转固定棘轮74与旋转棘轮72接合。 In this state, the ratchet wheel 74 rotationally fixed ratchet 72 engages with the rotation. 可以理解,当从卡盘系统去除偏压后,弹簧6会使旋转棘轮72 (并且输入轴10和输出轴30)运动到轴向向前的位置,这可使得棘轮72、74脱离。 Will be appreciated, when the bias is removed from the cartridge system, the spring 6 causes rotation of the ratchet 72 (and the input shaft 10 and output shaft 30) is moved to the axial forward position, which may allow the ratchet 72, 74 from.

[0044] 然后使用者启动驱动器,以旋转驱动输入轴10 (和旋转棘轮72 —起),而输入轴10将相对于旋轮固定棘轮74旋转。 [0044] The user then start the drive, the input shaft 10 to rotate the drive (and rotating ratchet 72-- onwards), and the input shaft 10 to rotate relative to the rotating wheel 74 fixed ratchet. 假如卡盘系统保持偏压,那么棘轮72、74之间的相对旋转就导致输入轴10、输出轴30和工具卡盘50相对于机壳90发生相对移位,从而产生往复的轴向运动。 If the bias voltage holding chuck system, then the relative rotation between the ratchet wheel 72, 74 to cause the input shaft 10, output shaft 30 and the tool chuck 50 with respect to the housing 90 relative displacement occurs, resulting in a reciprocating axial movement. 例如,如图所示,旋转棘轮72和旋转固定棘轮74均具有各自的齿。 For example, as shown, the rotation of the ratchet 72 and ratchet wheel 74 are rotationally fixed with their respective teeth. 当旋转棘轮72的齿骑在旋转固定棘轮74的齿之上的时候,旋转棘轮72沿轴向远离旋转固定棘轮、74。 When the rotation of the ratchet teeth 72 to ride over the ratchet teeth 74 fixed rotation when rotating ratchet 72 fixed axially away from the rotating ratchet, 74. 当齿彼此经过时,施加在卡盘系统上的偏压使旋转棘轮72回到如图5、6所示的轴向位置。 When the teeth to each other through, the bias voltage applied to the chuck system allows the axial rotation of the ratchet 72 back to the position shown in Fig. 5 and 6. 这样,当驱动器启动后,工具卡盘50将旋转以及轴向往复。 Thus, when the drive is started, the tool chuck 50 and the rotating axial reciprocating.

[0045] 图7、8所示为卡固模式。 [0045] Figure 7-8 for retaining mode. 仅仅作为示例,动力驱动器可在卡盘系统非偏压时(如图所示)处于卡固模式下操作。 Example only, the drive power can be (as shown) is in operation mode when the clamp chuck system is a non-biased. 旋转固定棘轮74处于轴向向后位置(并且脱离旋转棘轮72),以使锤击机构70停止。 Rotationally fixed ratchet 74 is in the axial rearward position (and the ratchet wheel 72 from rotating), so that the hammer mechanism 70 is stopped. 同时,使用者可将套筒60移动至轴向向后位置。 Meanwhile, the user may move the sleeve 60 to the axial rearward position. 在该轴向运动过程中,套筒60的后向花键66与卡盘驱动轴55的花键56脱离(因而卡盘驱动轴55相对于卡盘体52旋转),并且套筒凸耳68能够进入端盖94的凹穴98中(因而套筒60和卡盘体52能够旋转安装在动力驱动器的机壳90上)。 In this axial movement, after the sleeve 60 to the spline shaft 66 and the chuck 55 of splines 56 from (and thus the chuck shaft 55 chuck body 52 is rotated with respect to), and the sleeve lugs 68 able to enter the recess 98 in the end cap 94 (and thus the sleeve 60 and the chuck body 52 rotatably mounted 90 on the power drive enclosure).

[0046] 当套筒凸耳68进入凹穴98时,套筒凸耳68沿轴向向后方向驱动销8 (并因此驱动输入轴10)和克服弹簧6的影响。 [0046] When the sleeve 68 into the lug recesses 98, the sleeve lug 68 drive pin 8 axially rearward direction (and thus drive the input shaft 10) and overcome the effects of the spring 6. 输出轴30 (并因此连接部20)在凸缘34和轴承4之间的弹簧(图中未示出)的作用下,保持在轴向向前位置。 The output shaft 30 (and thus the connection portion 20) in the lower flange 34 and the bearing between the spring 4 (not shown) the role of maintaining in the axial forward position. 由此,输入轴10的轴向向后移动将导致驱动凸耳16部分地离开连接部20的从动凸耳26,以使驱动凸耳16的逐渐变细斜面能够在圆周方向面对从动凸耳26的逐渐变细斜面(如图8所示)。 Thus, axial rearward movement of the input shaft 10 will cause the drive lug 16 partly away from the connecting portion 20 of the driven lugs 26, so that the tapered ramp drive lug 16 in the circumferential direction to face the driven lug tapering chamfer 26 (shown in Figure 8).

[0047] 使用者可以启动驱动器来旋转驱动输入轴10。 [0047] The user can start the drive shaft 10 to rotate the drive input. 输入轴10通过驱动凸耳16和从动凸耳26的接合来旋转驱动输出轴30。 By driving the input shaft 10 and the driven lugs 16 engaging lugs 26 to rotate the drive output shaft 30. 输出轴30相对于卡盘体52 (通过套筒60旋转安装到机壳90上)旋转驱动卡盘驱动轴55。 The output shaft 30 relative to the chuck body 52 (rotatably mounted on the housing 90 through the sleeve 60) is rotationally driven chuck shaft 55. 如'503申请所述,卡盘驱动轴55和卡盘体52之间(并因此卡盘致动螺钉和卡爪)的相对旋转将致动工具卡盘50 (也就是根据动力驱动器的操作方向来打开和/或关闭卡爪)。 Such as the '503 application described, the chuck of the drive shaft (and thus the chuck actuating screw and claw) relative rotation of the actuating tool 50 between the chuck 55 and the chuck body 52 (i.e. according to the direction of operation of the drive power to open and / or close the jaws). 此外,在卡盘致动期间,卡盘体和卡爪不发生旋转。 In addition, during actuation chuck chuck body and claws do not rotate occur. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就称为所谓“静轴”特征。 Because the user is not likely to be affected (or observed) any rotating parts, which is a so-called "static axis" feature.

[0048] 在卡盘致动过程中,当工具卡盘50没有完全打开或关闭(例如当卡爪仍正在打开或关闭时),输入轴10可通过驱动凸耳16和从动凸耳26之间的相互作用旋转地驱动输出轴30。 [0048] In the chuck actuation process, when the tool chuck 50 is not fully opened or closed (e.g., when the jaws are still being opened or closed), the input shaft 10 via the drive lugs 16 and the lugs 26 of the follower Interactions between rotationally drive the output shaft 30. 当工具卡盘50完全关闭(有或没有插入的附件)或完全打开时,驱动凸耳16作用到从动凸耳26上的旋转力将加大。 When the tool chuck 50 is fully closed (with or without insertion of the accessory) or fully opened, the driving lug 16 is applied to the driven lugs 26 on the rotating force will increase. 该旋转力增加到一阈值,在此凸耳16、26的逐渐变细斜面相配合以在轴向向后方向上驱动输入轴10并克服弹簧6的影响,因此驱动凸耳16滑过从动凸耳26的末端。 The rotational force is increased to a threshold value, here 16, 26 of the lug is tapered ramps cooperate to drive in the axial direction of the input shaft 10 and rearward against the influence of the spring 6, thus driving the driven lug 16 over the projection end 26 of the ear. 在这种情况下,驱动凸耳16和从动凸耳26能够提供一离合特征,用来限制卡盘致动过程中所施加的转矩。 In this case, the drive lugs 16 and the driven lugs 26 to provide a clutch feature, intended to limit the torque of the chuck actuation process applied.

[0049] 可以理解,在轴向向后的方向上驱动输入轴10所需的旋转力的值受到如凸耳16、26的逐渐变细斜面的倾斜角度和/或弹簧6的弹簧常数的影响。 [0049] will be appreciated, the value of the drive input in the axial rearward direction of the shaft 10 of the rotational force required is affected lugs 16, 26 gradually increases as the inclination angle of the inclined surface and the thin spring constant and / or spring 6 . 此外,通过适当设计逐渐变细斜面的外形,可使紧固工具卡盘50的转矩阈值小于松开工具卡盘50的转矩阈值,反之亦然。 Further, by appropriately designing the shape of the tapered ramps, allows fastening tool chuck 50 is less than the torque threshold release torque threshold tool chuck 50, and vice versa.

[0050] 在图9-14所描述的实施例中,图9-14示意性地描述了一示例性而非限制性的工具卡盘150。 In the Figure 9-14 embodiment described, Figure 9-14 schematically depicts a illustrative and not restrictive tool chuck 150 [0050]. 该工具卡盘可应用于以上部分所描述的卡盘系统中。 The tool can be applied to chuck chuck system described in the above section. 如图9-14所示,工具卡盘150可移动地接收附件105的柄。 As shown in Figure 9-14, the tool chuck 150 movable handle 105 to receive attachments.

[0054] 弹簧106保持在卡盘体152和衬套110 (牢固连接到输出轴130上)之间。 [0054] The spring 106 is maintained between the chuck body 152 and the bushing 110 (firmly connected to the output shaft 130). 弹簧106在轴向后向方向上影响卡盘体152(并因此驱动套筒120)。 To influence the direction of the spring 106 in the axial direction of the chuck body 152 (and thus drive sleeve 120). 卡盘体152的轴向后向运动受到压靠衬套110的离合表面112的驱动套筒120的离合表面122的限制。 Restricted against clutch surface 110 of the liner 112 of the clutch surface 120 of the drive sleeve 122 to the axial movement of the chuck 152 after the.

[0055] 卡盘致动螺钉180包括径向通道186,卡爪101可分别经由这些通道滑动。 [0055] The chuck actuating screw 180 includes a radial channel 186, the pawl 101 is slidably through these channels, respectively. 径向通道186将卡盘致动螺钉180旋转固定到卡爪101上。 Radial passage 186 chuck actuating screw 180 rotationally fixed to the pawl 101. 螺纹128和188之间的相互作用引起卡盘致动螺钉180相对于卡盘体152在轴向上前进或后退。 Interaction between threads 128 and 188 cause the chuck actuating screw 180 152 relative to the chuck body forward or backward in the axial direction.

[0056] 卡盘体152的前端牢固地支撑凸头部140和爪固定器145。 The front end of the chuck body 152 [0056] firmly support the fixed jaw protruding head 140 and 145. 凸头部140为锥形,并围绕爪固定器145。 Convex head portion 140 is tapered and surrounds the prongs 145. 爪固定器145具有倾斜槽147 (如图10所示),卡爪101可以分别经过这些槽滑动。 Fixed pawl 145 has an inclined slot 147 (shown in Figure 10), pawl 101 can slide through these grooves, respectively. 卡爪101具有能沿着爪固定器145的逐渐变细外轮廓滑动的突片103。 Pawl 101 to slide along the pawl having a holder tapering outer contour 145 of tabs 103. 凸头部140的径向向内的表面压靠突片103的径向向外表面,以防止卡爪101从爪固定器145的槽147上移开。 Radially projecting head portion radially inwardly facing surface 140 against tabs 103 of the outer surface, in order to prevent pawl 101 away from the jaw holder groove 147 145. 可以理解,卡盘致动螺钉180、凸头部140和爪固定器145能够通过卡爪101旋转锁定在一起。 Be appreciated that the chuck actuating screw 180, the projection head 140 and the claw holder 145 can be rotated by the pawl 101 are locked together.

[0057] 套筒160可以通过配合特征安装在卡盘体152上,通过配合特征组件152、160可以相互轴向运动并且旋转锁定在一起。 [0057] sleeve 160 may be installed through the mating feature 152 on the chuck body, characterized by blending the components 152,160 may be axially and rotationally locked together with each other. 例如,套筒160具有前向花键163 (如图10所示),前向花键163与卡盘体152的花键153 (如图10所示)相互作用。 For example, the sleeve 160 having a forward spline 163 (Figure 10), the forward spline 163 and the chuck body 152 of the spline 153 (see Figure 10) interact. 套筒160具有凹穴168 (如图11所示),用以可选择地与机壳190的凸耳198接合。 Sleeve 160 has a recess 168 (shown in Figure 11), with the housing 190 for selectively lug 198 engages.

[0059] B.操作 [0059] B. Operation

[0060] 工具卡盘150根据套筒160轴向位置的不同能够以不同模式操作。 [0060] 150 tool chuck sleeve 160 can operate according to different axial positions in different modes. 这些不同操作模式包括(但并非限于)钻孔/驱动模式、装配模式和卡固模式。 These different modes of operation including (but not limited to) the drill / driving mode, and a retaining assembly mode mode.

[0061] 图12所示为钻孔/驱动模式。 [0061] Figure 12 is a drill / driving mode. 如图所示,套筒160定位在相对于卡盘体152的轴向中间位置。 As shown, the sleeve 160 is positioned at an intermediate position with respect to the axial direction of the chuck body 152. 在这种状态下,锁销157位于凹槽167中配设的两个斜面161、162之间。 In this state, the lock pin 157 is located between 161 and 162 disposed in the recess 167 of the two ramps. 套筒160的轴向位置在使用中会发生偏移。 The axial position of the sleeve 160, in use, offset will occur. 当这种偏移期间,斜面161、162和弹簧加载的锁销157相互作用,以影响套筒160回到所示的轴向中间位置。 When this offset period, the ramps 161, 162 and the spring-loaded locking pin 157 interact to affect the axial sleeve 160 back to the neutral position shown.

[0062] 此外,衬套110的花键116与套筒160的后向花键166接合,致使卡盘体152、卡盘驱动轴155 (包括衬套110和驱动套筒120)以及套筒160旋转地锁定在一起,并且作为一个单元旋转。 [0062] In addition, splines 116 of the liner 110 and rear sleeve 160 to engage the splines 166, so that the chuck 152, the chuck shaft 155 (including the bushing 110 and the drive sleeve 120) and a sleeve 160 rotationally locked together, and rotate as a unit. 这样,工具卡盘150在工作中不会松动。 Thus, the tool chuck 150 does not come loose at work.

[0063] 使用者启动驱动器,旋转驱动输出轴130,驱动输出轴130依次又旋转驱动工具卡盘150和附件105。 [0063] user boot drive, rotary drive output shaft 130, 130 in turn drives the output shaft rotary drive tool chuck 150 and 105 accessories.

[0064] 图13所示为装配模式。 [0064] Figure 13 shows the assembly mode. 使用者移动套筒160到轴向前向位置,以实现装配模、式。 Before a user moves the sleeve 160 to an axial forward position to achieve the loaded module, formula. 在这种轴向运动中,凹槽167的斜面161在径向向内方向上驱动锁销157,并克服弹簧159的影响。 In such axial movement, the groove 167 of the inclined surface 161 in a radially inward direction of drive lock pin 157, and to overcome the influence of the spring 159. 套筒160活动地保持在轴向前向位置,致使衬套110的一部分能暴露出来。 Sleeve 160 movably held in the axial forward position, causing a portion of the liner 110 can be exposed.

[0065] 衬套110的暴露部分可被工具抓持,以允许将工具卡盘150装配到动力驱动器的输出轴130上,或者将其从输出轴130上卸下。 Exposed [0065] 110 parts of the bush can be gripping tools to allow the tool chuck assembly 150 to the power output of the drive shaft 130, or remove it from the output shaft 130. 一旦释放活动保持时,斜面161和弹簧加载的锁销157就能够相互作用,以使套筒160回到如图12所示的轴向中间位置。 Upon release of movable holding time, ramp 161 and a spring loaded locking pin 157 is able to interact, such that the sleeve 160 back to the neutral position shown in FIG. 12 in the axial direction.

[0066] 图14所示为卡固模式。 [0066] Figure 14 is a retaining mode. 在此,使用者可将套筒160移到轴向后向位置。 After this, the user can move the sleeve 160 to axially position. 在该初始轴向移动时,凹槽167的斜面162在径向向内方向上驱动锁销157,并克服弹簧159的影响。 When the initial axial movement, the ramps 162 of the recess 167 in the radially inward direction drive locking pin 157, and to overcome the influence of the spring 159. 在进一步的轴向移动中,锁销157 (在弹簧159的作用下)沿径向向外方向移动,并跨过斜面164。 In a further axial movement, the lock pin 157 to move radially outward direction (under the action of the spring 159), and across the inclined surface 164.

[0067] 此外,套筒160的后向花键166脱离衬套110的花键116,以使卡盘驱动轴155 (包括衬套110和驱动套筒120)能够相对卡盘体152旋转。 [0067] In addition, the sleeve 160 of the bushing 110 from the splines 116 to the splines 166, so that the chuck shaft 155 (including the bushing 110 and the drive sleeve 120) relative to the chuck body 152 can rotate. 端盖194的凸耳198进入到套筒160的凹穴168中。 End cap 194 of the lug 198 into the recess 168 in the sleeve 160. 在这种状态下,套筒160、卡盘体152、凸头部140、爪保持器145和卡爪101能旋转地安装在动力驱动器的机壳190上。 In this state, the sleeve 160, the chuck body 152, the projection head 140, the claw 145 and the claw holder 101 rotatably mounted on the housing 190 of the power drive.

[0068] 然后使用者启动驱动器以旋转驱动输出轴130。 [0068] The user then starts the drive shaft 130 to rotate the drive output. 输出轴130可旋转驱动衬套110。 Output shaft 130 is rotatably driven bushing 110. 衬套110通过离合面112和122之间的接合而旋转驱动驱动套筒120。 Bushing 110 by engaging the clutch 112 and 122 between the surface and the drive sleeve 120 is rotationally driven. 驱动套筒120相对于卡盘致动螺钉180旋转,其(通过卡爪101、凸头部140、爪保持器145、卡盘体152和套筒160)保持在机壳190上。 The drive sleeve 120 with respect to the chuck actuating screw 180 rotates, (via pawl 101, the projection head 140, pawl holder 145, the chuck body 152 and sleeve 160) held on the housing 190. 这种相对旋转导致卡盘致动螺钉180通过径向向内面螺纹128和径向向外面螺纹188之间的相互作用,沿轴向方向上前进或后退(根据驱动套筒120的旋转方向)。 This relative rotation causes the chuck actuating screw 180 threaded through the radially inward surface 128 and radially outside of the interaction between threads 188, along the axial direction of the forward or backward (depending on the direction of rotation 120 of the drive sleeve). 卡盘致动螺钉180的这种移动能够推或拉卡爪101 (由爪保持器145上的倾斜槽147导引),以使其张开或闭合。 Chuck actuating screw 180 of this movement can push or pull-pawl 101 (by the holding pawl 145 inclined guide groove 147), so as to open or closed.

[0069] 在卡盘致动期间,套筒160、卡盘体152、凸头部140、爪保持器145、卡爪101和卡盘致动螺钉180保持旋转地安装在机壳190上,同时卡盘致动螺钉180可相对卡盘体152在轴向上移动(通过驱动套筒120的旋转运动),以张开或闭合卡爪101。 [0069] During actuation of the chuck, the sleeve 160, the chuck body 152, the projection head 140, pawl holder 145, the pawl 101 and the chuck actuating screw 180 holding rotatably mounted on the casing 190, while chuck actuating screw 180 relative to the chuck body 152 can be moved (by rotational movement of the drive sleeve 120) in the axial direction, in order to open or close the jaws 101. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就被称为所谓“静轴”特征。 Since the user is not susceptible to (or observe) any rotating parts, which is a so-called "mandrel" feature.

[0070] 输出轴30相对于卡盘体52 (其通过套筒60旋转地安装在机壳90上)旋转驱动卡盘驱动轴55。 [0070] Output shaft 30 with respect to the chuck body 52 (which is rotatably mounted on the casing 90 through the sleeve 60) is rotationally driven chuck shaft 55. 如'503申请所述,卡盘驱动轴55和卡盘体52 (并因此卡盘致动螺钉和卡爪)之间的相对旋转可致动工具卡盘50 (也就是根据动力驱动器的操作方向张开和/或闭合卡爪)。 Such as' 503 herein, chuck chuck shaft 55 and 52 (and thus the chuck actuating screw and claw) relative rotation between the actuatable tool chuck 50 (that is, according to the operation of power-driven orientation opening and / or closing the jaws). 此外,在卡盘致动过程中,卡盘体和卡爪不旋转。 In addition, the chuck actuating process, the chuck body and the claw does not rotate.

[0071] 在卡盘致动过程中,当工具卡盘150没有完全打开或关闭时(比如卡爪101仍正在打开或关闭时),衬套110通过离合面112和122之间的相互作用旋转驱动驱动套筒120。 [0071] In the chuck actuation process, when the tool chuck 150 is not fully opened or closed (for example, the pawl 101 is still being opened or closed), the interaction between the rotating bushings 112 and 122 through the clutch surface 110 drive drive sleeve 120. 当工具卡盘150完全关闭(有或没有插入的附件105)或完全打开时,衬套110施加到驱动套筒120上的旋转力可加大。 When the tool chuck 150 is fully closed (with or without insertion of the attachment 105) or fully opened, the liner 110 is applied to the rotational force on the drive sleeve 120 can be increased. 该旋转力增加到一阈值,在该阀值下离合面112和122就会让开(或滑动),以限制卡盘致动过程中施加的转矩。 The rotational force is increased to a threshold value at which threshold the clutch surface 112 and the opening 122 will allow (or sliding), to limit the chuck actuating torque applied during. 当离合面112和122滑动时,驱动套筒120 (与卡盘体152和套筒160 —起)将沿轴向向前方向被驱动并克服弹簧106的影响。 When the clutch sliding surfaces 112 and 122, the drive sleeve 120 (with the chuck body 152 and sleeve 160 - onwards) will be driven forward in the axial direction and to overcome the influence of the spring 106. 然而,应该理解,这种轴向向前运动(发生在离合滑动时)不足以使端盖194的凸耳198脱离套筒160的凹穴。 However, it should be understood that such axially forward movement (sliding occurs when the clutch) is not sufficient to enable the end cap 194 of the sleeve 160 from the lug 198 of the pocket.

[0072] 将可理解,在轴向向前方向上驱动驱动套筒120所需旋转力的值,受到如离合面112和122几何构造和/或弹簧106的弹簧常数的影响。 [0072] It will be understood, in the axially forward direction on the value of the desired rotational drive force of the drive sleeve 120, such as by the clutch surface 112 and 122 geometry and spring constant / or the influence of spring 106. 此外,通过适当设计离合面112和122的几何构造,使紧固工具卡盘150的转矩阈值小于松开工具卡盘150的转矩阈值,反之亦然。 Further, by appropriately designing the clutch surface 112 and 122 of the geometry, the fastening tool chuck 150 is smaller than the release torque threshold torque threshold tool chuck 150, and vice versa. ,
