BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the three-dimensional structure of the 8-shaped oil groove deburring device in the inner hole of the sleeve according to an embodiment of the utility model. DETAILED DESCRIPTION

[0011] In order to further understand the technical solution of the present invention, the technical solution of the present invention is now clearly and completely described through embodiments in combination with the accompanying drawings.

[0012] like Figure 1 The 8-shaped oil groove deburring device of the inner hole of the shaft sleeve of the utility model embodiment 1 comprises a rotary clamp, a corresponding drive controller, and a grinder 8. The drive controller comprises a speed regulating drive motor 1, and a speed regulator 2, etc.

[0013] .The rotary clamp includes two clamping wheels 6, which are spaced apart from each other and are located in contact with each other at the lower side of the corresponding workpiece 9. The two clamping wheels 6 are arranged on a fixed bracket 3 through a bearing device 7. The two clamping wheels 6 are connected to a synchronous pulley 4 through their wheel axles by a synchronous belt 5, and the synchronous pulley 4 is fixedly connected to a speed regulating drive motor 1.

[0014] The step pulley 4 and the speed regulating drive motor 1 are located at the upper part of the corresponding ends of the two clamping wheels 6, and the wheel shafts of the two clamping wheels 6 form a triangular distribution with the synchronous pulley 4. The speed regulating drive motor 1 is connected to a speed regulator 2.

[0015] In the present embodiment, the clamping wheel 6 is made of a nylon wheel. The grinder 8 is a handheld pneumatic grinder. The workpiece 9 is a shaft sleeve.

[0016] During processing, start the small speed-adjustable drive motor 1, adjust the appropriate speed with the speed regulator 2, and the speed-adjustable drive motor rotates through the synchronous pulley 4 and the synchronous belt 5 to drive the two nylon wheels to rotate in the same direction. Place the sleeve on the two nylon wheels in a free state without clamping. The two nylon wheels use the self-gravity of the sleeve to rub against it and then drive the sleeve to rotate. The handheld pneumatic grinder 8 is placed on the edge of the 8-shaped oil groove in the inner hole of the sleeve, and the rotation of the sleeve drives the pneumatic grinder to move along the oil groove, thereby removing the flanging and burrs on the edge of the 8-shaped oil groove. Because the nylon wheel rotates slowly, there is no need to stop the machine to pick up and place the workpiece, and the workpiece can be processed continuously with a fast processing speed.

[0017] In another embodiment of the utility model, three clamping wheels are arranged around the corresponding side wall of the workpiece at intervals. This can make the frictional rotation dynamic clamping operation between the workpiece and the clamping wheel more stable and increase the operating speed to a certain extent. The remaining structures and corresponding working operation methods of this example are similar to those of the above embodiment.

[0018] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
