Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to a tooling for inserting a compressor main bearing seat and a rotor into a shell. Background Art

[0002] The compressor motor is an electric motor used to drive the compressor, which is mainly used to compress gas into high-pressure gas or liquid;

[0003] During the production and manufacturing of compressor motors, the operator is required to press the rotor into the outer casing. Since there are eight strong magnets inside the rotor with strong magnetic attraction, the operator needs to use all his strength to press the rotor when the rotor enters the outer casing, which is time-consuming and labor-intensive and reduces work efficiency. Every time the main bearing seat and the rotor enter the shell, the shell will be adsorbed and pressed down together. The main bearing seat is inside the shell and is made of iron, so the main bearing seat will be adsorbed when the rotor enters the shell. During the process of the shell being adsorbed and lowered with the main bearing seat, the shell shifts, and the exposed copper wire inside the shell will rub against the main bearing seat, causing the main bearing seat to shift and the stator copper wire to be scratched. The product's insulation and voltage resistance cannot be met, and the product is unqualified, which seriously affects the product quality.

[0004] Therefore, those skilled in the art provide a compressor main bearing seat and rotor shell inserting tooling to solve the problems raised in the above background technology. Utility Model Content
