Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and in particular to an assembly line for end cap components of a new energy motor. Background Technology

[0002] An electric motor typically consists of a stator, rotor, windings, bearings, cooling system, and housing. Different types of motors (such as DC motors, AC induction motors, stepper motors, and permanent magnet synchronous motors) differ in structure, but their basic components follow similar principles.

[0003] Through in-depth research on motor assembly, people have designed various assembly fixtures of different sizes, making motor assembly easier, more efficient, and with consistent quality. However, these scattered assembly fixtures can only perform their respective functions. For example, in the traditional motor end cover assembly, bearing pressing and rotor shaft pressing are required before assembly, and both of these need to be completed on different equipment. After the pressing step is completed, the parts need to be transferred to the next processing equipment for further processing. This processing method has problems such as large workload, low assembly accuracy, poor continuity and coordination in motor end cover assembly processing, and low assembly processing efficiency. Therefore, this invention proposes a new energy motor end cover assembly line to solve the problems existing in the prior art. Summary of the Invention

This assembly line combines the bearing pressing mechanism and the rotor shaft pressing mechanism through a double-speed chain conveyor, achieving high-precision and high-efficiency assembly of motor end cap components. The assembly process of motor end cap components exhibits good continuity and improved coordination, requires less human intervention, and achieves high assembly consistency, thereby reducing the labor intensity of employees.
