AI Technical Summary
Existing gas spring strength testing devices cannot adapt to gas springs of different specifications, have poor testing flexibility, and the length of the cylinder pressure head is insufficient when testing small gas springs, making it impossible to effectively resist them.
A gas spring strength testing device was designed, comprising a base, a clamping mechanism, and a testing mechanism. The height of the testing mechanism can be adjusted by adjusting the screw on the support column and the motor to accommodate gas springs of different specifications. Multiple clamping holes and clamping components are set on the clamping platform to achieve simultaneous testing of multiple gas springs.
It improves the flexibility and efficiency of gas spring testing, can adapt to the testing of gas springs of various specifications, and ensures that even small gas springs can be effectively tested.
