Description

Technical Field

[0001] The invention belongs to the technical field of clutch seal detection, and relates to a fast watertight detection device and method for a clutch housing. Background Art

[0002] As the automotive industry and related machinery manufacturing sectors continue to evolve, gearboxes, as critical power transmission and speed change components, have a performance and quality that directly impacts the operational stability, efficiency, and service life of the entire mechanical system. In recent years, with the industry's increasingly stringent requirements for product quality, the sealing requirements for gearboxes have become increasingly stringent. This is because gearboxes contain numerous precision gears, bearings, and other components, which require specific lubrication conditions to minimize wear, reduce heat, and ensure smooth power transmission. Once a gearbox's sealing fails, impurities such as dust and moisture can easily infiltrate, causing lubricant deterioration and increased component wear, leading to failures, seriously impacting the normal operation of the machinery, and potentially even causing safety accidents. Gearbox sealing is not an isolated issue; it is closely and inextricably linked to the sealing of the housing components. Therefore, sealing testing of these housing components is essential.

[0003] However, current practices for testing the sealing properties of housing components rely heavily on traditional watertightness testing methods. In large-scale production environments, this inefficient testing method severely constrains production schedules and fails to meet the demands of rapid and efficient production. Operators must perform repetitive movements such as handling, inserting, and removing parts for extended periods, which not only leads to fatigue but also increases the risk of human error. Consequently, the inefficiency and labor-intensive nature of traditional watertightness testing methods present significant challenges for companies in improving testing throughput and efficiency.

[0004] In summary, the traditional watertight detection method has low detection efficiency and high labor intensity, which has brought certain troubles to the work of increasing the quantity and efficiency of the watertight detection process. It is urgent to design an automated and rapid watertight detection equipment for the clutch housing. Summary of the Invention
