Active and passive integrated all-metal micro-vibration control device

Abstract

The invention discloses an active and passive integrated all-metal micro-vibration control device which comprises a supporting rod, diaphragm springs and the like. The supporting rod penetrates in a first shell inner cylinder, and a coil support is fixedly installed at the other end of the supporting rod through a supporting plate. A voice coil motor rotor is installed on the coil support and moves transversely between an inner ring permanent magnet and an outer ring permanent magnet of a voice coil motor stator in the axial direction. One end of a metal spring is fixedly installed at the connecting opening position of a second shell and a first shell through an end cover, and the other end of the metal spring is matched with the end portion of a limiting sleeve. The limiting sleeve is supported in the second shell through a metal rubber gasket. The metal spring is connected with external equipment through an inner thread at the end portion and presses the limiting sleeve. The diaphragm springs are installed between the supporting rod and an end cover of the first shell, between the coil support and the inner wall of the end cover of the first shell and between the supporting plate of the coil support and the end cover of the metal spring. According to the active and passive integrated all-metal micro-vibration control device, wide-frequency-band micro-vibration control can be achieved, the vibration isolation effect of a vibration isolator is improved, and adaptability to various complex environments is improved.

Description

technical field [0001] The present invention designs an active and passive integrated all-metal micro-vibration control device, which is suitable for suppressing the micro-vibration generated by the mechanism during operation or reducing the impact of environmental disturbance on sensitive equipment. Background technique [0002] With the development of science and technology, the accuracy and resolution of equipment and loads are getting higher and higher, and the stability requirements of the working platform where they are located are also getting higher and higher. The micro-vibration of the environment exists widely for a long time. Inevitably, it will inevitably have an adverse effect on the stability of the platform, and further affect the full performance of the sensors and other equipment. Therefore, a stable working platform becomes a prerequisite for the normal operation of high-performance sensors and other equipment, and micro-vibration control is the key to impr...
