AI Technical Summary
The existing disc motor case airtightness detection device cannot rotate the disc motor when fixed, resulting in multiple fixes required to be fixed multiple times when detecting multiple waterways, which is inconvenient to operate and affects the detection speed. At the same time, the sealing element contacts the case with the case without buffering, resulting in mechanical fatigue and casing damage.
A detection device including a support plate, a lifting assembly and a drive assembly is designed. The connecting plate is pushed downward on the surface of the guide rod through the lifting assembly, driving the sealing element to move downward and seal with the casing, reducing the casing pressure with the spring rebound, and driving the measurement assembly to move through the drive assembly for airtightness detection. When other waterways need to be detected, the storage plate and the cabinet are rotated through the transmission chain and gear system to achieve convenient detection of multiple waterways.
The device can rotate the housing when fixing the housing, which facilitates detection of multiple waterways, reduces the housing pressure through the spring, increases the detection speed, and avoids housing damage.
