Description

Technical Field

[0001] This utility model relates to the field of motor housing processing technology, specifically a fixed tooling for motor housing processing. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor housing refers to the outer shell of the motor. During machining processes such as cutting and drilling, the motor housing needs to be fixed with fixtures to ensure stability during machining.

[0003] Existing fixtures for machining motor housings, such as the one disclosed in CN220498527U, have the advantages of improving cleaning efficiency and device positioning. However, these fixtures are inconvenient for separately fixing the inner and outer ends of the motor housing. Consequently, it is inconvenient to switch and adjust the fixtures and retract the jigs during machining of the inner or outer ends of the motor housing. Therefore, we propose a fixture for machining motor housings. Utility Model Content
