Description
Technical Field
[0001] The present invention belongs to the technical field of motor rotor magnetic shoe assembly, and specifically relates to an assembly tool for motor rotor magnetic shoe. Background Art
[0002] In today's automobile industry, with the rapid rise of new energy vehicles, the market for new energy vehicles is expanding, and the demand for new energy vehicles is increasing. The quality and stability of motors, the core functional components of new energy vehicles, determine the stability of power control and the guarantee of safe driving of each new energy vehicle.
[0003] At present, in the automatic production line for motor rotor assembly, from casing loading, magnetic tile loading, magnetic tile gluing to casing magnetic tile assembly, each process uses independent tooling and fixtures. When the motor rotor is transferred between different processes, the assembly size error of the motor rotor becomes larger due to the change of clamping and fixing tooling, and the quality and performance are unstable.
[0004] The quality and performance problems of the motor will be transmitted and affect the safety performance of the entire vehicle, causing traffic accidents and endangering the lives of the passengers. During the assembly of the motor rotor, the manipulator clamps the magnetic tile and the housing. After the magnetic tile is glued, the housing and magnetic tile are assembled. Each process has an independent manipulator and clamping tooling. The positioning method of each tooling is different, and the repeatability and reproducibility are biased. The existing process cannot meet the high-precision requirements of the motor.
[0005] In the prior art, the patent name is: A fixture structure suitable for magnetic tile assembly, and the patent number is: CN205992843U. It provides a fixture structure suitable for magnetic tile assembly, which enables the magnetic tile and the housing to be automatically assembled on the production line. The entire assembly process is quick and convenient, ensuring the efficient and accurate production of the entire production line, and the quality of the products produced is good. It includes an upper fixture and a lower fixture. The lower fixture includes a base, an upper positioning structure, and a center positioning shaft. The center positioning shaft is convex on the base. The upper part of the center positioning shaft is an arc transition structure that closes upward. The upper positioning structure includes a plurality of arc-structured magnetic tile positioning blocks. The magnetic tile positioning blocks are combined to form a circular structure. A magnetic tile positioning spacer is arranged between adjacent magnetic tile positioning blocks. A guide wheel is arranged at the inner end of the bottom of each magnetic tile positioning block. The inner end of each guide wheel is in close contact with the outer end face of the arc transition structure of the center positioning shaft. The outer side of the bottom of each magnetic tile positioning block is in close contact with one end of the first guide spring at the corresponding position.
[0006] In the prior art, two complex special-purpose casing clamps and magnetic tile clamps are matched to achieve the matching magnetic tile assembly by overlapping and pressing down from top to bottom. However, this form makes the nested structure too complicated, and the dimensional accuracy requirements for the mutual matching are also extremely high, which makes it impossible to simply and efficiently use it on an automated robotic arm production line. It requires complex debugging and adaptation, and the installation and maintenance costs are extremely high. It also requires that the casing and magnetic tiles are almost nested for clamping and installation, which leads to extremely high dimensional requirements for the casing and magnetic tiles, and a small acceptable tolerance response, which can easily cause the automated production line to stop due to errors.
