AI Technical Summary

Technical Problem

In the prior art, the detection of the sealed vehicle shock absorber housing cannot reflect the sealing situation in the dynamic state, resulting in inaccurate detection results.

Method used

A shock absorber housing detection device is designed, including a fixing mechanism, an air pump, a pressure detector and a deflection jitter mechanism. The shock absorber housing is fixed through a fixing mechanism, the air pump is fed into the air, the pressure detector detects the air pressure, and the deflection and jitter mechanism simulates the movement state of the shock absorber housing during the car's driving.

Benefits of technology

The sealing detection of the shock absorber housing in three states: static, dynamic, and then static, improving the accuracy and practicality of the detection.

Abstract

The invention discloses a shock absorber housing detection device and a detection method thereof, comprising a bottom plate and a shock absorber housing, and also comprising: a vertical cylinder, a sliding rod, a fixed folding rod, a rotating folding rod, a placement plate, a fixing mechanism, a deflection and shaking mechanism, an air pump, a connecting hose, an air intake pipe and a pressure detector. The shock absorber housing is placed on the placement plate, the fixing mechanism fixes the shock absorber housing, the air pump sends gas into the shock absorber housing, the pressure detector detects the internal air pressure of the shock absorber housing, thereby detecting the air tightness of the shock absorber housing, and then the deflection and shaking mechanism drives the shock absorber housing to deflect and shake, thereby simulating the movement state of the shock absorber housing during the driving process of the car, and detecting the air tightness of the shock absorber housing at the same time, after the movement, the pressure detector is stationary for a period of time, and the internal air pressure of the shock absorber housing is detected again, so as to achieve the simulation of the driving process of the car, and the pressure detector detects the internal air pressure of the shock absorber housing at the same time.
