After each clamping assembly 240 is clamped with a workpiece, the lifting mechanism 400 is started to drive the polishing mechanism 200 to descend, so that each workpiece is inserted into the medium.
Then, the power mechanism drives the rotating shaft 210 to rotate, the rotating shaft 210 drives each polishing unit to synchronously rotate through the rotating seat, meanwhile, the driving assembly drives the driving shaft 224 to rotate, the driving shaft 224 drives the turntable 231 to rotate, the turntable 231 can drive each B gear 233 to revolve around the driving shaft 224 due to the fact that the turntable 231 is fixedly connected with the driving shaft 224 and the B fluted disc 232 is fixedly connected with the sleeve 221, the B gear 233 can rotate due to the fact that the B gear 233 is meshed with the B fluted disc 232, the B gear 233 drives each clamping seat 241 to rotate through the hollow shaft 242, and therefore rotation of the adjusting clamping seat 241 and revolution around the driving shaft 224 can be achieved.
