Process application of special motor assembly method

The invention discloses a process application of a special motor assembly method. The process application comprises a motor, a tooling platform and the assembly method. The tooling platform comprisesa tooling base, a central positioning device, a lifting tooling and a pad block. The motor comprises a rotor, a stator, a motor shell, a rear end bearing, a hollow inner spline shaft, a sealing ring and a bearing. The assembly method is implemented by the steps of: S1, assembling one end bearing and the sealing ring in position by means of the tooling platform; S2, positioning an assembly toolingof the motor radially by means of an outer spigot of the motor shell of the motor; S3, guiding and correcting the motor rotor for assembly by means of the assembly tooling, so as to ensure assembly quality; S4, directly using the assembly tooling as an assembly platform; S5, guiding and correcting the rear end bearing of the motor for assembly by adopting the tooling platform, and then performingcold pressing in place; S6,
