Embodiment

For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.

Hereafter composition graphs 1 and Fig. 2 explain the formation of the grinding plant of the present invention. Wherein Fig. 1 illustrates the section of structure of the grinding plant according to the present invention, and Fig. 2 illustrates the sectional view according to the integrated cylinder body in the grinding plant of the present invention.

As can be seen from Figure 1, grinding plant comprises the major partss such as integration cylinder body 1, turning axle 2, outer cutter 7 and interior cutter 6 substantially. Described integration cylinder body 1 is integrally processed to form, and does not have dismountable separating component. Such as, a kind of material in described cylinder body whole utilization stainless steel, aluminium alloy or any suitable metal or non-metallic material etc. is made. Being processed with rotary shaft hole in cylinder body 1, it is for through turning axle 2 (it can be known in fig. 2 and find out).

Rotary shaft hole 2 is processed with the first mutually concentric bearing hole 8, the 2nd bearing hole 9 and grinding knife hole 10 (can know in fig. 2 and find out) further. The position in wherein each hole is not necessarily limited to the position shown on figure, and can be the various positions of principle and the spirit not running counter to the present invention. Described processing can be the techniques such as cutting, such as, by numerically-controlled machine (CNC) etc. Certainly, it can also adopt the mode of casting to process. As seen from Figure 2, cylinder body 1 is divided into bearing to connect section A, cavity segment B and grinding knife connection section C according to function, its centre bearer connects section A and is provided with described first and second bearing holes 8,9, cavity segment B for holding raw material to be ground, and grinding knife connects section C and is provided with grinding knife hole 10. As seen from Figure 2, due to the first bearing hole 8, the 2nd bearing hole 9 and grinding knife hole 10 be all integration cylinder body in be processed to form, and and without any need for assembling technique, therefore can ensure the level that the concentricity of three reaches very high, and finally make the quality of fit between outer cutter and interior cutter very high.

In a preferred embodiment, the quantity in described bearing hole differs and is decided to be two, and it can also be three or more than three.

And according to preferred embodiment, after cylinder body 1 first processes two bearing holes and grinding knife hole, reprocess out the cavity for holding raw material and for enter material enter to expect hole 11. This can further improve the concentricity between bearing hole and grinding knife hole. The diameter of described cavity is preferably bigger than the diameter in bearing hole, and it can be arranged as required and suitably in the length of axis. In addition, described cavity is optional, and it can be removed as required, as long as ensureing to be communicated to grinding knife hole into material hole. And described cavity is not necessary between described bearing hole and described grinding knife hole in the position of axis, it can such as between two bearing holes.

Returning Fig. 1 again, after assembling, turning axle 2 is rotatably coupled to described cylinder body 1 by the first bearing 4 and the 2nd bearing 5 laid respectively in the first bearing hole 8 and the 2nd bearing hole 9. Bearing wherein can adopt the mode such as rolling bearing or sliding surface bearing. And outer cutter 7 is set in described grinding knife hole 10, described interior cutter 6 is set on described turning axle 2 so that described interior cutter and described outer cutter cooperatively interact to realize grinding. And the fixing mode of outer cutter and interior cutter can adopt mode and/or other any suitable modes of keyway. Such as flat key is set in grinding knife hole, and cutter arranges corresponding groove outside, or vice versa. Flat key is set in addition in turning axle, and groove is set in interior cutter, or vice versa. And preferably, in order to ensure outer cutter in the axial direction fixing, it is possible to adopt and outer cutter is fixed on it cylinder via screw and pressing plate or other fastener means, to suppress moving axially of outer cutter.

In addition, at the top of described turning axle, set nut 12 is installed, fixes to ensure the axis of described turning axle 2. Preferably, the locking direction of this set nut 12 is contrary with turning axle 2 sense of rotation operationally.

Fig. 3 illustrates according to the visual angle, top of integrated cylinder body in the grinding plant of the present invention and the stereographic map at visual angle, bottom. Wherein can know from the stereographic map of Fig. 3 the bearing seen in a body 1 connect section A and formed around it enter to expect hole. Those skilled in the art should be understood that, this enters to expect that the quantity in hole is not limited to three shown in Fig. 3, and its quantity can be one, two, four or more.

Setting device in the grinding plant of the application is described below with reference to Fig. 1. Wherein the position between bearing hole and interior cutter on described turning axle is provided with whisker 13. Described whisker 13 is preferably arranged against the boss near described bearing hole that is positioned on turning axle. In addition, against described interior cutter, adjustment knob 14 is installed in the bottom of described turning axle. Regulate knob 14 to be threaded connection and it is coupled to turning axle 2, and moving up and down at axial direction due can be realized by rotating. And due to interior cutter 6 be moveable in the axial direction, suitably moving in the axial direction so rotating 14 adjustable interior cuttves 6 by regulating and controlling, to regulate the tolerance clearance between interior cutter 6 and outer cutter 7, thus realizing the adjustment of mesh-of-grind. Certainly, those skilled in the art should be understood that, when the grinding plant not needing mesh-of-grind to regulate, it is possible to save above setting device, and described interior cutter can be fixedly connected on described turning axle, is also namely fixing at axial direction due.

Fig. 4 shows the schematic diagram of a kind of example using state of the grinding plant according to the present invention. Wherein fixedly mount rotation handle 15 further at the turning axle top of grinding plant, to realize the function of hand-ground. Certainly, when electric grinding, it is also possible to electric motor is directly or indirectly connected to described turning axle. In addition, can selection of land, the bottom of grinding plant is provided with powder cup 16, its can be used for receive grinding after raw material. Certainly, it is also possible to adopt other forms of storage device to receive grinding rear raw material, such as containing tube etc.

The following method describing the cylinder body manufacturing the grinding plant according to the present invention according to Fig. 5. The method comprises the following steps:

501, it is provided that integration cylinder body, this body can adopt the casting of suitable metallic substance and become, or by by bulk raw cutting section and cut further. Can selection of land, this body can have cylindrical shape, and the location benchmark using this cylindrical shape as following operation.

502, cutting centre hole in described cylinder body, this centre hole can be used as rotary shaft hole.

503, cut described centre hole further, to form the first concentric bearing hole, the 2nd bearing hole and grinding knife hole. The processing sequence in above hole is not fixing, it is possible to according to circumstances change. This cutting can adopt numerically-controlled machine to complete, to improve precision as far as possible.

504, the position between described bearing hole and grinding knife hole processes raw material cavity, and comes in and goes out material hole to be connected described raw material cavity in the processing of side, described bearing hole. Processing described raw material cavity and described enter to expect that the order of step in hole can replace, the procedure of processing of described raw material cavity is not necessarily in addition, it is possible to save.

Finally, it is also possible to there is the treatment step carrying out other at described cylinder with it, such as, in the bottom machining screw of described cylinder body to connect optional powder cup, and required keyway etc. is processed in described grinding knife hole.
