Abstract

The invention discloses a bistable shock absorber which comprises a bistable plate and an upper supporting frame, the upper supporting frame is formed by welding two C-shaped steel sheets in a crossed mode, the four corners of the bistable plate are connected to the upper supporting frame, a stand column and a lower base are arranged in the center of the bistable plate, and the stand column and the lower base are connected together and clamp the bistable plate. A guide rod is arranged below the lower base and sleeved with a spring, and the two ends of the spring abut against the opposite faces of the lower base and the upper supporting frame. Center holes for the guide rod to move up and down are formed in the centers of the stand column and the lower base. According to the bistable shock absorber, the layout is compact, the structure is simple, the connection mode is mainly welding, the reliability in a vibration environment is greatly improved, the mass is reduced, the dual vibration reduction effect is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of shock absorbing accessories, in particular to a bistable shock absorber. Background technique [0002] In engineering applications, due to the impact, each component is prone to vibration. In order to improve the smoothness of the lathe or other construction machinery and prevent mechanical damage caused by vibration or resonance, a shock absorber is installed in parallel with the vibration component and the mechanical base. , in order to attenuate the vibration, most of the shock absorbers in the existing mechanical structure are hydraulic shock absorbers or spring shock absorbers. The piston moves up and down, and the oil in the shock absorber will repeatedly flow from one cavity through the pores to another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy is conve...
