flexible shock absorber

Abstract

The invention discloses a flexible shock absorber, which includes a flexible support mechanism and a precision guide mechanism. The flexible support mechanism includes a bracket, an upper bracket, a lower bracket, two horizontal flexible plates, and two vertical flexible plates. The left ends of the two horizontal flexible boards are respectively fixed on the upper bracket and the lower bracket, and the right ends are respectively fixed on the upper and lower bumps of the bracket; the upper ends of the two vertical flexible boards are respectively fixed on the upper bracket The upper and lower ends of the left and right sides are respectively fixed on the left and right sides of the lower bracket; the vertical flexible board includes a plurality of side-by-side upper strips and lower strips, and the horizontal flexible board includes a plurality of horizontal strips. The multiple horizontal strips of the lower horizontal flexible plate are respectively inserted into the gaps between the multiple upper strips and the multiple lower strips of the right vertical flexible plate and are interdigitated; the precision guide mechanism includes Base, spring, guide sleeve, piston rod, piston and guide cylinder. The invention has the advantages of simple and compact structure, good damping effect and high positioning accuracy.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a flexible shock absorber. Background technique [0002] Most of the consequences of vibration are harmful. In order to reduce the harmful consequences of vibration, a carrier is needed to isolate or reduce the harm of vibration. This carrier is called a shock absorber. With the continuous improvement of modern science and technology and production level, the mechanical structure is becoming more and more high-speed, complex and lightweight, and the vibration problem caused by it is more prominent. The existence of vibration not only affects the service life of mechanical equipment, causes equipment damage, but also affects people's work efficiency, and even endangers human health. Therefore, it has become increasingly important to use shock absorbers to protect mechanical equipment from shocks. [0003] Since the shock absorber was produced, it has been widely used in aviation, aerospace, s...

Problems solved by technology

But in the prior art, shock absorbers are mostly rubber products or a combination of metal and rubber products. Although the shock absorption effect is good, they also expose many shortcomings when they play a role in shock absorption.

For example, the shock absorber itself has natural vibration, and the damping is too small, and the vibration isolation ability near the resonance frequency is relatively poor; the rubber shock absorber is restricted by its own material, easy to age, the natural frequency is relatively high, the compression rate is small, and the performance Unstable and short service life

The disadvantage of the damping shock absorber is that the oil seal requires high requirements, the process is complicated, and it is not easy to maintain. When the cylinder is changed by a large impact from the outside, it cannot work.

Moreover, the existing shock absorber has poor positioning accuracy and complex structure
