[0002] Asynchronous motors have many components. To ensure molding accuracy, each component needs to be carefully processed before leaving the factory.

[0022] The clamping assembly 8 includes a plurality of first L-shaped plates 81 arranged on the outside of the first fixed cylinder 6.

In this way, it can be flexibly and quickly adjusted according to the inner diameter of the motor housing. The electric push rod 102 is connected to the output end of the conductive slip ring 17 through a wire.

[0026] Working principle: First, the staff places the motor casing on the top of the processing table 5 in a state of being inserted into the outside of the clamping assembly 8, and then starts the electric push rod 102 according to the inner diameter of the motor casing, and uses the push-pull column 103 to drive the second fixed cylinder 7 to slide vertically on the outside of the first fixed cylinder 6, so that the friction pad 83 on the arc plate 82 on one side of the first L-shaped plate 81 is tightly fitted with the inner wall of the motor casing, thereby completing the fixing work of the motor casing with different inner diameters, and the operation is convenient and flexible. During processing, when it is necessary to change the processing surface of the motor casing, start the motor 131 to drive the processing table 5 to rotate through the gear 132 and the inner ring 12, and make the casing on the top of the processing table 5 rotate to another processing surface, so as to achieve quick adjustment of the casing processing surface.
