Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] A grinding rod 6 is hinged on each of the plurality of hinged rods 13, and the plurality of grinding rods 6 are limited by a limiting mechanism. A connecting shaft 12 is fixedly connected to the connecting edge 17, the connecting shaft 12 is rotatably connected to a connecting disk 9 through a rotary bearing, and the connecting disk 9 is connected through a clamping mechanism to fix the shaft core 19. The moving sleeve 14 is adjusted by an adjusting mechanism. By adjusting the position of the moving sleeve 14 on the connecting edge 17 through the adjusting mechanism, the inclination angle of the hinged rod 13 is adjusted, so as to adjust the position of the grinding rod 6, so that the grinding rod 6 can abut against shaft cores 19 with different diameters, and at the same time ensure that the axis of the shaft core 19 coincides with the rotation axis of the motor 4, thereby ensuring the contact between the grinding rod 6 and the surface of the shaft core 19 and ensuring the grinding effect.

[0021] The adjusting mechanism includes a threaded rod 15, the threaded rod 15 is rotatably connected to the connecting edge 17 through a bearing, a fixed ear 16 is fixedly connected to the moving sleeve 14, and the threaded rod 15 threadedly penetrates through the fixed ear 16. By rotating the threaded rod 15, the position of the moving sleeve 14 on the connecting edge 17 is adjusted, so as to adjust the hinge of the hinged rod 13 and move the grinding rod 6.

[0022] The limiting mechanism includes a limiting sleeve 11, the limiting sleeve 11 is fixedly connected to the connecting shaft 12, a limiting post 10 can be inserted into the limiting sleeve 11, and the limiting post 10 is fixedly connected to the grinding rod 6. The limiting post 10 and the limiting sleeve 11 are used to limit the grinding rod 6, so as to prevent the grinding rod 6 from moving laterally during adjustment.

[0023] The clamping mechanism includes a telescopic rod 3, the telescopic rod 3 is fixedly connected to the support frame 2, a butting block 8 is fixedly connected to the telescopic rod 3, the butting block 8 abuts against the shaft core 19, and an anti-slip pattern is provided on the surface of the butting block 8 that abuts against the shaft core 19. By extending the telescopic rod 3, the butting block 8 abuts against and fixes the shaft core 19, so that the shaft core 19 does not rotate when the grinding rod 6 rotates, thereby playing a role in grinding.

[0024] During processing, the shaft core 19 is placed between multiple grinding rods 6. Subsequently, the threaded rod 15 is rotated to adjust the position of the adjusting moving sleeve 14 on the connecting edge 17, thereby adjusting the inclination angle of the articulated rod 13, causing the multiple grinding rods 6 to move and abut against the shaft core 19. Subsequently, the telescopic rod 3 extends, causing the abutting block 8 to abut and fix the shaft core 19. The motor 4 rotates to drive the grinding rods 6 to rotate, thereby performing grinding.
