Abstract： At present, the new energy vehicle industry develops rapidly, and China attaches increasing importance to the development of electric vehicle as a national strategy. Electrical motor, as the core part, reliability and stability of its driving power output are also the goals of the major automakers. This paper innovatively proposes the use of automatic bolt tightening machine to accurately control the assembly process and reverse force test of the drive axle shaft and motor. Through theoretical calculation, the gear drive and slide rail mechanism are designed, and the 3D design is carried out by CATIA. The electrical passes the safety monitoring through PLC, the output and the reverse test results are input into the production quality monitoring system in real-time. The stability test shows that the assembly time is shortened, the assembly reliability and production efficiency are improved greatly.
