[0002] In the motor manufacturing industry, the airtightness of the motor housing is one of the important indicators of the quality. If there is an air leakage problem in the motor housing, it indicates that there are defects in the manufacturing process of the motor housing, which will affect the durability and safety of the motor after assembly and use. Therefore, in the motor production process, the airtightness detection of the motor housing is an indispensable production link.

[0003] Traditional motor airtightness detection methods often rely on manual operation and simple detection equipment. This method is not only inefficient, but also the detection results are easily affected by human factors, resulting in difficult to guarantee the detection accuracy and reliability. Moreover, traditional detection methods also have potential safety hazards, such as accidents may be caused by improper operation; although there have been some airtightness detection equipment with low automation on the market at present, their structures are complex, the operation is cumbersome, and the maintenance cost is high. At the same time, these equipment have poor detection accuracy and flexibility. After detection, the motor housings need to be manually marked and stored separately, and the degree of intelligence is low.

[0004] In view of this, we propose an airtightness detection tooling for a motor housing to solve the existing problems. Content of the Utility Model
