Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and more particularly to an assembly device and an assembly method for a horizontal split permanent magnet motor. Background Art

[0002] At present, with the iterative upgrade of the technology of new energy vehicle manufacturers, some manufacturers require the provision of split permanent magnet motors, with the motor rotor directly mounted on the gearbox, and the front cover of the motor and the end cover of the gearbox are combined into one. The stator and rotor of the split permanent magnet motor are assembled at the customer's site. After the motor is installed and the rotor is fixed, the stator is inserted horizontally. During the assembly process, the stator is inserted into the stator due to the combined effect of the adsorption generated by the strong magnet and gravity, causing the stator to vibrate strongly during the entire suction process, and the end of the motor stator winding is prone to scratches and bumps, and the motor is prone to burn during operation.

[0003] Traditional stator-rotor assembly devices are mostly vertical assembly, with the stator fixed and the rotor inserted from top to bottom, ignoring the influence of gravity on motor assembly. However, this device is only applicable to the case where the motor has a separate end cover. In addition, traditional stator-rotor assembly devices assemble the stator and rotor as a whole and then assemble the whole machine into the gearbox. There is no such situation where the rotor is fixed and the stator is inserted horizontally. Therefore, traditional stator-rotor assembly devices cannot solve the current assembly problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a horizontal split permanent magnet motor assembly device and assembly method, which enable the stator of the split permanent magnet motor to be smoothly assembled and inserted horizontally after the motor rotor is suspended and installed. The structural design of the frame, fixture seat, movable module and clamping mechanism makes this device not only suitable for one type of motor, but can also realize the stator and rotor assembly of motors on multiple platforms.

[0005] To achieve the above object, the present invention provides the following technical solutions:
