AI Technical Summary
Traditional leak testing fixtures have low efficiency in changing the mating joints, resulting in low testing efficiency for automotive control valves and affecting the cycle time of automated production lines.
Design a quick-change fixture for airtightness testing, including a lower fixture mounting plate and an upper fixture mounting plate. The lower fixture mounting plate has a built-in air passage, and integrates a male connector and an air passage interface. The upper fixture mounting plate integrates a female connector and a second connector. The upper fixture mounting plate can be quickly replaced in a modular manner to adapt to control valves of various specifications. The fixture uses a positioning pin, a quick-change knob and an air lock to achieve quick connection and sealing.
It improves the sealing reliability and changeover efficiency of the tooling, adapts to multiple specifications of control valves, improves the testing efficiency of control valves, and enhances the versatility and production cycle of the tooling.
