Description

technical field [0001] The invention relates to the technical field of assembling a motor coding disc for a vehicle, in particular to an assembling process of a motor coding disc. Background technique [0002] At present, traditional automotive motors use magnetoelectric encoders and resolvers as motor speed information acquisition components. Although magnetoelectric encoders have fewer installation structure specifications, their signal accuracy is lower; resolver signal accuracy is lower, and installation structure specifications There are many, corresponding to the number of poles of the motor, resolvers of different specifications must be selected. The use of photoelectric encoders can meet the needs of automotive drive motors with high precision in both hardware manufacturing and software processing. The installation of traditional automobile motor speed signal acquisition components adopts the split hole-shaft matching method, and the interference fit between the sma...

Problems solved by technology

The installation of traditional automobile motor speed signal acquisition components adopts the split hole-shaft matching method, and the interference fit between the small shaft and the main shaft hole is used to provide the synchronous rotation power of the rotating parts of the signal device. Its structure requires high machining accuracy of the hole shaft, and the motor The shaft can easily affect the matching accuracy of the hole and shaft during the heat treatment process

[0003] Chinese patent ZL201210419202.0 discloses a photoelectric encoder that is easy to install. It includes a housing and a base. The base is rotatably connected to a blind hole shaft. The blind hole shaft is threaded to the motor shaft. Together with the photoelectric conversion module and printed circuit board inside the casing, it is used as a speed signal generator to transmit the motor speed signal to the outside, but the structure is connected by a segmented shaft thread, and the rotation accuracy of the rotating code disc is not high, and the accuracy of the code disc itself is biased. Low, difficult to adapt to high-precision control requirements

Chinese patent ZL201020685432.8 discloses a self-adaptive support installation device for photoelectric encoders, which has a certain self-adaptive ability and can solve the problem of damage to the photoelectric encoder due to large serial movement of the motor rotor in the axial direction during operation to a certain extent. However, the stability and reliability of the articulated arm need to be tested
