Description

Technical Field

[0001] The utility model belongs to the technical field of motor shell processing, in particular to a motor shell processing tooling which can prevent processing deformation. Background Art

[0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is divided into electric motors and generators. Motor accessories refer to the parts assembled in the motor by the motor manufacturer. They are called original motor accessories. Parts that are replaced due to damage caused by improper use or wear are called motor accessories. Generally, the life of accessories is not as long as that of original parts.

[0003] During the motor processing, the surface of the motor shell needs to be micro-processed, and most of the existing processing tools use extended claws to clamp the motor shell for processing. However, since most motor shell parts have very thin walls, this method can clamp the motor shell, but it will cause the motor shell to be deformed due to force, making it difficult to ensure the processing requirements of the motor shell with high roundness requirements.

The positioning slot is opened on one side of the base plate body and fits tightly with the lathe spindle, and the cross-section of the positioning slot is a triangular structure.

[0012] Furthermore, threaded holes are evenly formed on one side of the motor housing close to the tooling body.
