[0025] A spray plate 6 is fixedly connected to one side of the polishing table 2 , a recovery box 12 is arranged below the spray plate 6 , and one side of the recovery box 12 is snap-connected to the polishing table 2 .

[0026] The protective plate 1 can be used to shield one side of the polishing table 2 to reduce the flying of debris when the piston is polished. One end of the hydraulic push rod 4 is connected to the polishing table 2 to reinforce the installation of the hydraulic push rod 4. The hydraulic push rod 4 can be used to push the guide plate 11 to move, thereby adjusting the position of the guide plate 11 and the power box 3. The motor 2 9 and the transmission assembly 10 can drive the rotation of the polishing wheel 1 8. The motor 1 7 can drive the rotation of the polishing wheel 2 15. The polishing wheels 1 8 and 15 can be used to polish different positions of the piston. The piston can be inverted and then rinsed and inserted into the limit sleeve 14 to complete the polishing process on both ends of the piston. The coolant sprayed from the spray plate 6 can reduce the residue of debris on the surface of the piston. Embodiment 2

[0027] like Figure 3-Figure 5 As shown, the bottom of the limit plate 13 is fixedly connected to a support tube 19 through an L-shaped piece, the bottom of the support tube 19 is fixedly connected to a gear 20, one side of the gear 20 is meshed with a rack 16, one side of the rack 16 is fixedly connected to an electric push rod 17, and one end of the electric push rod 17 is fixedly connected to the polishing table 2.

[0028] A gear ring 22 is rotatably connected to the top of the support cylinder 19, and a gear 18 is meshed with the inner wall of the gear ring 22. The bottom of the gear 18 is rotatably connected to the support cylinder 19, and the top of the gear 18 is fixedly connected to the limit sleeve 14. A gear 3 23 is meshed with one side of the gear 18, and the bottom of the gear 3 23 is fixedly connected to the output shaft of the motor 3 21, and one side of the motor 3 21 is fixedly connected to the inner wall of the support cylinder 19.

[0029] The support cylinder 19 can be used to support the bottom of the limit plate 13, and the gear 2 20 is installed at the bottom of the support cylinder 19. The electric push rod 17 can drive the rack 16 to move back and forth. When the rack 16 moves, it can drive the gear 2 20 to rotate, and the support cylinder 19 and the limit plate 13 can rotate synchronously. The motor 3 21 can drive the gear 3 23 to rotate. Both sides of the gear 3 23 rotate with the gear 1 18. Therefore, when the gear 3 23 rotates, the two gears 18 can rotate, and then the limit sleeve 14 can be rotated. Since the piston is installed in a limited position inside the limit sleeve 14, when the limit sleeve 14 rotates, the piston can rotate with the limit sleeve 14 to realize the self-rotation of the piston.

[0030] The method of use and working principle of the device are as follows: first, insert the piston to be polished into the limiting sleeve 14, rotate the bolt on the limiting sleeve 14, and the end of the bolt abuts against the side wall of the piston to limit the piston, and use the motor 3 21 to drive the gear 3 23 to rotate, and use the gear 3 23 to drive the two gears 18 to rotate, so as to realize the self-rotation of the limiting sleeve 14 and the piston. When the gear 18 rotates, the gear ring 22 rotates between the limiting plate 13 and the support cylinder 19, and at this time, the outer ring surface and the outer ring surface of the piston can be polished by the polishing wheel 18 and the polishing wheel 2 15 respectively. The top is polished. During polishing, the spray plate 6 can be used to spray coolant. Excess coolant can pass through the filter plate 5 into the recovery box 12, and is filtered and collected by the filter screen obliquely arranged in the recovery box 12. The coolant can be recovered after the recovery box 12 is taken out. The electric push rod 17 can be used to drive the rack 16 to move along one side of the inner wall of the polishing table 2. When the polishing table 2 moves, the gear 2 20 can be driven to rotate, thereby realizing the rotation of the support cylinder 19 and the limit plate 13, changing the position of the piston, and moving the other piston to the bottom of the polishing wheel 2 15.
