The specific embodiment
Saw bit protective of the present invention mechanism includes a saw blade seat, a sawing assembly, a lifting assembly, and a baffle plate.This saw blade seat has an inclined guide groove, one first stop section, and one second stop section, and this first stop section is adjacent to the top of this inclined guide groove, and this second stop section is adjacent to the bottom of this inclined guide groove; This sawing assembly is hubbed at this saw blade seat, and has a motor and a saw blade, and this motor is combined with this saw blade via the inclined guide groove of this saw blade seat; This lifting assembly is located at this saw blade seat, and is connected with this sawing assembly, can drive this sawing assembly pivotable, makes the inclined guide groove lifting along this saw blade seat in the process of pivotable of this sawing assembly; This baffle plate is hubbed between this motor and this saw blade, and cover the inclined guide groove of this saw blade seat, have simultaneously two arc flange, this two arc flange is connected to respectively the first stop section and second stop section of this saw blade seat, make this baffle plate can produce pivotable in the process of this sawing assembly lifting, in order to this inclined guide groove is remained on the state that covers.
Thus, no matter this saw blade rises to a use location or drops to one not during the use location, the inclined guide groove of this saw blade seat all can be covered by this baffle plate, allow maintenance personal's hand can't pass this inclined guide groove, avoid in order to reach the purpose that hurt by this saw blade, and can promote simultaneously the crumb loading effect.
In order to describe structure of the present invention, feature and effect place in detail, enumerate a preferred embodiment and coordinate accompanying drawing to elaborate.
See also Fig. 3 and Fig. 4, the saw bit protective mechanism 20 of the table saw machine that provides for a preferred embodiment of the present invention includes a saw blade seat 30, a sawing assembly 40, a lifting assembly 50, and a baffle plate 60.
The central authorities of saw blade seat 30 have an inclined guide groove 31, and have one first arc guide channel 32 in the left side of inclined guide groove 31, and have a horizontal guide channel 33 in the right side of inclined guide groove 31, as shown in Figure 4.In addition, the limit, top side of saw blade seat 30 forms one first stop section 34 in the top end of adjacent tilted guide groove 31, and saw blade seat 30 has the catch 35 of a bending, flanging formation one second stop section 36 of catch 35 in place, the bottom locking of adjacent tilted guide groove 31.
Lifting assembly 50 has a runner 51, a driving screw 52, a guide screw piece 53, a first connecting rod 54, and a second connecting rod 55.Driving screw 52 passes saw blade seat 30 with the one end right edge is connected with runner 51, makes driving screw 52 can be subjected to the driving of runner 51 and rotates; Guide screw piece 53 is bolted in the other end of driving screw 52, and pass the horizontal guide channel 33 of saw blade seat 30 with the one end, and insert in the 3rd arc guide channel 424 of fixed head 42, as shown in Figure 4, make guide screw piece 53 can be subjected to the driving of driving screw 52 and move back and forth along the horizontal guide channel 33 of saw blade seat 30, and in mobile process via driving fixed head 42 pivotables, produce pivotables with related motor 44; First connecting rod 54 is hubbed between motor 44 and saw blade 46, and is embedded at the one end in the first arc guide channel 32 of saw blade seat 30; The other end of one end pivot joint first connecting rod 54 of second connecting rod 55, the other end is hubbed at saw blade seat 30, and embeds in the second arc guide channel 422 of fixed head 42, as shown in Figure 4.
Baffle plate 60 is hubbed between motor 44 and saw blade 46, and covers the inclined guide groove 31 of saw blade seat 30, has simultaneously one first arc flange 62, one second arc flange 64, and one the 4th arc guide channel 66.The first arc flange 62 of baffle plate 60 is connected to the first stop section 34 of saw blade seat 30, the second arc flange 64 of baffle plate 60 is connected to the second stop section 36 of saw blade seat 30, and 66 of the 4th arc guide channels of baffle plate 60 can be embedded for the first connecting rod 54 of lifting assembly 50 and the articulated section of second connecting rod 55.
Be more than the detailed construction of saw bit protective of the present invention mechanism 20, below describe with regard to use procedure of the present invention and characteristic again.
in the time saw blade 46 will being dropped to as shown in Figure 7 not use location P2 from as shown in Figure 5 use location P1, leader 512 by runner 51 drives runner 51 rotations, make driving screw 52 can be subject to the driving of runner 51 and drive guide screw piece 53 and move towards the direction away from sawing assembly 40, in the process that guide screw piece 53 moves, the fixed head 42 of sawing assembly 40 will be pulled, make motor 44 produce pivotable as the axle center take the articulated section of fixed head 42, and drive saw blade 46 drop to gradually not use location P2 along the inclined guide groove 31 of saw blade seat 30 in the pivotable process, as Fig. 4, Figure 6 and Figure 7.in the process that saw blade 46 descends, baffle plate 60 can produce pivotable by the second arc flange 64 of itself and the butt relation between the second stop section 36 of saw blade seat 30, and the curvature of the first arc flange 62 of utilization design itself, allow baffle plate 60 in the process of pivotable not can and the first stop section 34 of saw blade seat 30 between produce and interfere, in addition, the 4th arc guide channel 66 of baffle plate 60 can be left along with the pivotable of the decline of sawing assembly 40 and baffle plate 60 in the first connecting rod 54 of lifting assembly 50 and the articulated section of second connecting rod 55, thus, when saw blade 46 drops to not use location P2, baffle plate 60 still can remain on the state that covers with the inclined guide groove 31 of saw blade seat 30, maintenance personal's hand just can be subject to stopping of baffle plate 60 and can't pass the inclined guide groove 31 of saw blade seat 30, avoid to reach the purpose that hurt by saw blade 46.
on the other hand, when saw blade 46 when never use location P2 rises to use location P1, baffle plate 60 is understood with the butt relation generation pivotable between the first stop section 34 of the first arc flange 62 of itself and saw blade seat 30, and designed by the curvature of the second arc flange 64 own, allow baffle plate 60 in the process of pivotable not can and the second stop section 36 of saw blade seat 30 between produce and interfere, and, the first connecting rod 54 of lifting assembly 50 and the articulated section of second connecting rod 55 also can embed in the 4th arc guide channel 66 of baffle plate 60 along with the pivotable of the rising of sawing assembly 40 and baffle plate 60, to avoid baffle plate 60, produce between first connecting rod 54 and second connecting rod 55 and interfere.
It is worth mentioning that, saw bit protective of the present invention mechanism 20 can also provide a shield 70, it is fixed in saw blade seat 30, and be positioned at the top of inclined guide groove 31, as Fig. 3 and shown in Figure 7, has simultaneously a breach 72, the end shape of the form fit inclined guide groove 31 of breach 72, the screening effect that provides in order to increase baffle plate 60.
Comprehensive as can be known above-mentioned, no matter be in use location P1 or use location P2 not at saw blade 46, the baffle plate 60 that saw bit protective of the present invention mechanism 20 provides can remain on the state that covers with the inclined guide groove 31 of saw blade seat 30, hurt by saw blade 46 and reach the purpose that promotes the maintenance security with the hand of avoiding maintenance personal or other people, in addition, by the screening effect of baffle plate 60, the cutting swarf of workpiece can effectively be concentrated, in order to reach the purpose that promotes the crumb loading effect.
The constituent components that the present invention discloses in previous embodiment only for illustrating, is not to limit the scope of the invention, the alternative or variation of other equivalent elements, and the claim scope that also should be the present patent application contains.
