Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and particularly to an assembly line for a new energy motor end cover assembly. Background Art

[0002] A motor generally consists of parts such as a stator, a rotor, windings, bearings, a cooling system, and a housing. Different types of motors (such as DC motors, AC induction motors, stepper motors, and permanent magnet synchronous motors) have differences in structure, but their basic compositions follow similar principles.

[0003] Through in-depth research on motor assembly, people have designed various assembly tools of different sizes, making motor assembly easier, more efficient, and with unified quality. However, scattered assembly tools can only play their respective roles. For example, for a traditional motor end cover, bearing pressing and rotor shaft pressing need to be carried out before assembly, and both of these need to be completed on different devices. After the previous pressing is completed, it needs to be centrally transferred to the next processing device for processing. Such a processing method has problems such as a large amount of labor, low assembly accuracy, poor continuity and coordination in the assembly and processing of the motor end cover, and low assembly and processing efficiency. Therefore, the present invention proposes an assembly line for a new energy motor end cover assembly to solve the problems existing in the prior art. Summary of the Invention
