Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a quick processing structure for an integrated motor casing. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines.

[0003] Most of the motor barrels and back covers on the market are split-type and need to be processed separately before assembly. The split-type assembly not only has poor sealing effect and is prone to errors, but its processing and assembly process is also relatively cumbersome. In addition, the traditional motor barrel needs to be processed separately on its outer wall and inner wall, and requires multiple clamping. The casing processing has problems such as long mechanical processing time, high labor costs, low production efficiency, and low processing accuracy.

[0004] When installing the front cover of a traditional motor barrel, reinforcing ribs or ears are required to be provided on the motor barrel to open the front cover installation space. The reinforcing ribs not only consume too much material, but also affect the heat dissipation of the shell, and the structural stability of the ears is relatively poor. Utility Model Content
