The rotary clamping mechanism is used for rotating the rotor at a fixed angle, and does not need a worker to manually rotate the rotor, so that the production efficiency is improved. Wherein, the rotary clamping mechanism can select the existing equipment with both rotary function and clamping function, such as a rotary clamper manipulator; the rotary clamping mechanism can also be formed by a combination of a device with a rotary function and a device with a clamping function, such as a combination of a motor and a pneumatic clamping jaw, so that the pneumatic clamping jaw is fixed at the output end of the motor.

Preferably, a tip mechanism is arranged on the left side or the right side of the positioning seat and used for limiting the axial movement of the rotor. The axial movement of the rotor is limited by the arrangement, so that the rotor is prevented from moving under the action of the polishing head, and insulating paint in the groove of the commutator can be polished completely.

The invention has the advantages that the paint of the insulating paint in the groove of the commutator can be removed, and the commutator can not be damaged.
