AI Technical Summary
Existing gas spring life testing devices can only push and pull in one direction, which cannot simulate the actual use scenario of gas springs, resulting in inaccurate testing. Furthermore, they can only test a single or limited number of gas spring models, making them impractical.
A detection device including horizontal and vertical guide rails was designed. The combined movement of the first and second sliders simulates the actual use scenario of the gas spring. The first and second linear drive components drive the sliders to move in the horizontal and vertical directions respectively, realizing multi-directional detection of the gas spring.
It improves the accuracy of gas spring lifespan testing and is applicable to various models and sizes of gas springs, thus expanding its application range.
