AI Technical Summary
At present, there is a lack of dedicated inspection tools for the curved structure and opening position of the 159 end cap of liquefied natural gas cylinders for vehicles, which makes quality inspection difficult, inefficient and inaccurate in dimensional measurement.
An inspection device comprising a limiting disc and limiting posts was designed. Several limiting posts are set on the limiting disc, and the limiting posts are consistent with the circular holes of the gas cylinder end cap. The geometric dimensional qualification of the end cap is judged by the cooperation between the limiting posts and the circular holes. The device is made of aluminum alloy to improve accuracy and convenience.
It enables rapid and accurate inspection of gas cylinder caps, reduces workload, improves testing efficiency, and the device is reusable and easy to operate.
