Device for detecting variable-force impact performances of hydraulic buffer

Abstract

The invention relates to the field of detection devices, and especially relates to a device for detecting variable-force impact performances of a hydraulic buffer. The device comprises a substrate, an installation frame, a telescoping impact structure, and a hydraulic buffer installation structure. A to-be-detected hydraulic buffer is installed and fixed on the hydraulic buffer installation structure, and a telescoping driving device is stably installed on a cross beam and impacts on the to-be-detected hydraulic buffer installed on the hydraulic buffer installation structure stably and precisely, thereby enabling the to-be-detected hydraulic buffer to make compressing and stretching recovery movement. Preferably, the driving end of the telescoping driving device is provided with an impact force inductor, thereby enabling a gravity to be continuously located between the telescoping end of the telescoping driving device and the telescoping end of the to-be-detected hydraulic buffer, and detecting the number of impact times of the to-be-detected hydraulic buffer and the amplitude of the impact force at each time in the whole detection process more precisely, and achieving the detection of the working performance of the hydraulic buffer in a variable force impact environment.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a detection device for detecting the variable force impact performance of a hydraulic buffer. Background technique [0002] Such as figure 1 The hydraulic shock absorber shown is composed of a cylinder (12) sealed to store buffer fluid and a telescopic rod whose lower end slides inside the cylinder (12), and whose upper end can be telescopic. In practical applications, the telescopic end of the telescopic rod (11 ) and the cylinder body are respectively installed and fixed on two relatively movable parts, and the buffering effect between the two moving parts is realized by extruding the buffer fluid and the elastic member inside the cylinder body through the telescopic rod. [0003] Hydraulic shock absorbers are mainly used in mechanical transmission, hydraulic transmission, and pneumatic transmission mechanisms. In order to avoid the impact force generated by the rapid relative...

AI Technical Summary

Problems solved by technology

The quality of the hydraulic buffer directly affects the performance, service life, and reliability of the entire equipment. Once there is a problem with the hydraulic buffer, it may cause damage to the equipment if it is serious, and its economic loss is irreparable. Accurate performance testing of hydraulic shock absorbers is particularly important

However, in the prior art, it is difficult to realize the long-term monitoring of the product quality of hydraulic shock absorbers by relying on experience such as manual feeling and visual inspection, so a hydraulic shock absorber detection equipment is needed to complete such work
