[0002] The motor, also known as an electric motor or motor, is a device that converts electrical energy into mechanical energy. The motor housing is an important part of the motor and has many important functions. First, it provides physical protection for the components inside the motor to prevent dust, moisture, foreign matter, etc. from entering the motor, thereby avoiding interference and damage to the normal operation of the motor. Secondly, the motor housing helps to dissipate heat. During the operation of the motor, heat is generated. The design of the housing can increase the heat dissipation area and dissipate the heat through air convection and other methods to ensure that the motor works within a suitable temperature range. Furthermore, the motor housing can play the role of electromagnetic shielding, reducing the impact of electromagnetic radiation generated by the motor when it is running on the outside world, and also reducing the interference of the external electromagnetic field on the inside of the motor. The materials of the motor housing are varied, and the common ones are cast iron, cast aluminum, steel plate, etc. Different materials have different characteristics. For example, the cast iron housing has high strength and good wear resistance; the cast aluminum housing has light weight and excellent heat dissipation performance; the steel plate housing has relatively low cost.

[0003] During the assembly process of the motor housing, the motor stator needs to be pressed into the housing. In the prior art, the motor stator is placed at the open end of the motor housing, a tubular workpiece matching the motor housing and the motor stator is placed on the motor stator, and the motor stator is pressed into the motor housing by a hydraulic device. However, this process lacks fixation of the motor housing and has certain risks, which is not conducive to the assembly of the housing.
