AI Technical Summary
The existing single-station design of the small water heater testing machine cannot meet the needs of mass production, resulting in a longer production cycle. Furthermore, the simple tooling support structure causes workpiece orientation and misalignment, leading to inaccurate connection of the testing interface and problems such as misjudging air leaks or missing the actual leak point.
A dual-station airtightness testing device is adopted, combined with a tooling lifting mechanism and contour positioning tooling, including a main cylinder, mounting plate, lifting frame, air passage hole of positioning block, positioning guide auxiliary head and photoelectric sensor, to achieve precise positioning and synchronous detection of workpiece.
It enables parallel dual-station inspection of small kitchen water heater workpieces, reducing the waiting time for loading, inspection, and unloading, improving inspection efficiency and accuracy, and avoiding misjudgment and air leakage caused by directional deviation and positional misalignment.
