The clamping assembly comprises an insulating base 23, an end clamping cylinder 24 and two side clamping cylinders 25. The insulating base 23 is fixed with two positioning rods 231. The end clamping cylinder 24 and the two side clamping cylinders 25 are fixed on the rotary table 22. The piston rods of the end clamping cylinder 24 and the side clamping cylinders 25 are fixed with insulating clamping blocks. The insulating base 23 and the insulating clamping blocks are made of silicon nitride ceramic material.

[0020] The shell heating mechanism 3 and the pressure resistance tester 4 are arranged adjacent to each other on the workbench 1. The rotary table 22 is sequentially provided with a feeding work station 221, a heating work station 222, a pressure resistance testing work station 223 and a motor installation work station 224. The shell heating mechanism 3 is arranged beside the heating work station 222, and the pressure resistance tester 4 is arranged beside the pressure resistance testing work station 223. The shell heating mechanism 3 comprises a lifting cylinder 31, a lifting table 32 and a high-frequency heater 33. The lifting cylinder 31 is vertically fixed on the workbench 1 and is used to drive the lifting table 32 to lift. The lifting table 32 is fixed with four guide rods at the bottom. The workbench 1 is provided with guide holes corresponding to the positions of the guide rods. The high-frequency heater 33 is fixed on the lifting table 32.
