Adjustable vibration isolator

Abstract

The invention provides an adjustable vibration isolator. Stronger damping force is provided by a resonance area, so that damage to equipment is avoided; the damping force of an isolation area is weak as much as possible, so that vibration damping efficiency is improved; moreover, the damping force and rigidity of a vibration damper can be regulated according to the state of the equipment. According to the technical scheme, a mounting core 4 is arranged in a casing 1, wherein the top of the mounting core 4 extends out from an open hole in the top of the casing 1; a space between the upper surface of a disk of the mounting core 4 and the inner side of the top of the casing 1 is filled with an upper metal wire mesh pad 5; a blocking piece 6 is arranged between the upper metal wire mesh pad 5 and the inner side of the top of the casing 1; a damping force regulation knob 2 is in screw joint with an internal thread at the lower part of the inner surface of the casing 1; a rigidity regulation knob 8 is in screw joint with the interior of a screw hole in the center of the damping force regulation knob 2; an annular lower metal wire mesh pad 3 is arranged above the damping force regulation knob 2; a rigid spring 7 is arranged between a cavity in the lower part of the mounting core 4 and the upper surface of the damping force regulation knob 2.

Description

technical field [0001] The invention belongs to the technical field of equipment vibration isolation and buffering, and relates to the development of a novel wire mesh vibration isolator. Background technique [0002] In recent years, the restrictions on vibration in engineering have become more and more strict, mainly because the requirements for precision in engineering have become higher and higher, the sensitivity of testing instruments has been significantly improved, and the vibration environment has become increasingly complex. Comfort requirements are putting increasing pressure on manufacturers. This makes the requirements for equipment shock absorbers more and more stringent. [0003] The existing wire mesh shock absorber has good damping characteristics, which can provide high damping in the resonance area of ​​the equipment or when it is subjected to an impact load, so as to avoid damage to the equipment due to unbearable damage. In the vibration isolation area,...

AI Technical Summary

Problems solved by technology

Existing wire mesh vibration isolators are generally only developed and used for one type of equipment. When the equipment state changes or the vibration conditions change, the stiffness and damping of the shock absorber remain unchanged, and the vibration damping effect of the shock absorber attenuates, even causing equipment damage.
