Background

Due to the high-speed development of robots and electric vehicles, the demand of motors is more and more large, and the existing motors are labor-intensive in production, so that manufacturers need to bear high labor cost, and manual operation often causes the problems of difficult quality control and low production efficiency.

The motor shaft of motor often is the first step of motor processing, and the locating hole on the motor shaft terminal surface is the benchmark of follow-up processing, so the required precision of terminal surface processing of motor shaft is high, and current manpower processing, the defective rate can be very high. In the automatic production process, after the motor shaft with the processed end face is grabbed from the numerical control processing machine, the motor shaft needs to be positioned, the automatic production can be continued, and the cylindrical surface of the electrode shaft needs to be subjected to rough machining and fine machining. After the cylindrical surface of the electrode shaft is finished, the position of the electrode shaft where the bearing is installed needs to be superfinished. Then, the surface of the rotor core on the rotor needs to be polished and deburred, so that the quality problem of the motor caused by residual burrs is prevented.

Polishing also belongs to machining, so that although large burrs are removed, there are still minute burrs and metal powder, which causes a problem that short circuits easily occur in the motor, and uniform painting is required for rust-proofing the outer circumferential surface of the rotor core.

After painting, a motor bearing needs to be installed on a motor shaft, the operation is very time-consuming and labor-consuming, and the precision is difficult to control due to manual assembly.
