Intelligent vibration isolation device for precision machine tool

Abstract

The invention relates to an intelligent vibration isolation device for a precision machine tool. At present, no intelligent vibration isolation device which is reasonable in structural design and is remarkable in vibration damping effect is available for the precision machine tool. The intelligent vibration isolation device is characterized by comprising a detection unit, a control unit and an executing unit, wherein the detection unit is used for detecting the vibration direction, frequency and amplitude of external vibration through a PVDF (Polyvinylidene Fluoride) piezoelectric slice, converting the external vibration into an electric signal through a signal processing system, and correcting and amplifying the electric signal to provide an executing parameter; the control unit is used for receiving the signal from the detection unit, working out data which is opposite to the external vibration in phase but identical in amplitude, and converting the data into an electric signal; the executing unit is used for receiving the electric signal from the control unit, converting the electric signal into a motion signal by using an inverse piezoelectric effect and counteracting and weakening the external vibration through self deformation for realizing vibration damping and vibration isolating functions; and the executing unit, the control unit and the detection unit are sequentially connected. The intelligent vibration isolation device is reasonable in structure design, remarkable in vibration damping effect, and reliable in performance.

Description

technical field [0001] The invention relates to a vibration isolation device, in particular to an intelligent vibration isolation device for a precision machine tool, which can reduce the impact of external vibration on the machine tool. Background technique [0002] During the working process of precision machine tools, the vibration of the external environment will affect the machining accuracy of the equipment, and even cause the equipment to fail to operate normally. Therefore, it is very necessary to use vibration isolation measures to effectively isolate the vibration from the outside and the disturbance of the equipment load. Generally, the damping materials used in commonly used vibration isolation devices are mostly polymer materials such as rubber and resin. It mainly uses the viscoelastic effect and friction effect in polymer materials to convert mechanical vibration energy into heat energy, so as to achieve the purpose of vibration reduction. However, the maximu...
