Then the servo motor 155 is started to drive the spur gear 154 to rotate reversely. The spur gear 154 drives the front and rear racks 153 to move outward and reset. The racks 153 drive the front and rear positioning plates 151 to move outward and reset. When the front and rear positioning plates 151 reset and are separated from the ball, the servo motor 155 is turned off. The ball can be clamped and fixed to polish the surface. In this way, the deviation of the front and rear positions of the ball can be prevented to affect the accurate contact with the polishing belt 5, so that the ball can be accurately polished by the polishing belt 5.

[0039] When the polishing belt 5 rotates to polish the surface of the ball, part of the debris will be attached to the polishing belt 5. The brush 17 can remove the debris attached to the polishing belt 5. The polishing belt 5 after removing the debris continues to polish the surface of the ball. In this way, the debris attached to the polishing belt 5 can be prevented to affect the subsequent use effect, so that the use effect of the polishing belt 5 is improved.
