Meanwhile, the lifting driving mechanism 330 lifts the clamping jaws 310, then the rotating driving mechanism 320 rotates the clamping jaws 310 from the transportation mechanism 110 to the base 213, the lifting driving mechanism 330 drives the clamping jaws 310 to fall, at this time, the clamping jaws 310 release the motor rotor 101 and place the motor rotor 101 in the accommodating cavity 2131, and then the lifting driving mechanism 330 lifts the clamping jaws 310 and rotates the clamping jaws 310 to the transportation mechanism 110 by the rotating driving mechanism 320 to wait for the arrival of the motor rotor 101 of a next batch. After the motor rotor 101 is placed in the accommodating cavity 2131, the limiting mechanism 215 fixes the motor rotor in the accommodating cavity 2131, and the motor rotor is driven by the rotating assembly 214 to rotate. Meanwhile, the abrasive belt wound on the tray 222 is driven by the belt-moving mechanism 224 to move, and the rotating motor rotor 101 is polished. The motor shaft polishing device is reasonable in design and compact in structure, and effectively solves the technical problems of low efficiency, low qualified rate of finished products and high labor cost of manual polishing of the motor shaft in the conventional polishing mode.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
