Description

Technical Field

[0001] This invention belongs to the field of clutch seal testing technology, and relates to a rapid watertight testing device and method for clutch housing. Background Technology

[0002] In the continuous development of the automotive industry and related machinery manufacturing fields, the transmission, as a key power transmission and speed change component, directly affects the operational stability, efficiency, and service life of the entire mechanical system. In recent years, with the industry's increasing demands for product quality, especially the stringent requirements for the sealing of transmission products, the situation has become increasingly complex. This is because the transmission contains numerous precision gears, bearings, and other components that require specific lubrication environments to reduce wear, lower heat generation, and ensure smooth power transmission. Once a transmission experiences sealing problems, external dust, moisture, and other impurities can easily penetrate, leading to lubricant deterioration, accelerated component wear, and ultimately, malfunctions. This severely impacts the normal operation of mechanical equipment and may even cause safety accidents. The sealing performance of transmission products is not isolated; it is closely and inextricably linked to the sealing performance of housing components. Therefore, sealing performance testing of housing components is essential.

[0003] However, current practices for testing the sealing performance of housing components primarily rely on traditional watertightness testing methods. In large-scale production environments, this inefficient approach severely restricts production schedules and fails to meet the demands for rapid and efficient production. Operators are required to perform repetitive actions such as handling, immersing, and removing parts for extended periods, which not only easily leads to physical fatigue but also increases the risk of human error. Therefore, the inefficiency and high labor intensity of traditional watertightness testing methods pose a significant challenge to companies in improving testing output and efficiency.

[0004] In summary, traditional watertightness testing methods are inefficient and labor-intensive, which poses a challenge to improving the efficiency and effectiveness of the watertightness testing process.
