Abstract

The invention discloses a liquid driving type super mini shift control device and method, which is composed of elastic mini shift structure and liquid driving control structure through connecting hinge, wherein the spring of elastic mini shift structure and one end of elastic mini shift bridge are fixed on the machine body; the other end of spring connects the other end of elastic mini shift bridge; the working bench and chuck are set on the left end of elastic mini shift bridge; the liquid driving control structure contains floating chamber within liquid, liquid meter and control device; the marking chamber of liquid driving control structure is set in the floating chamber and suspends in the liquid; the marking chamber contains liquid, whose quantity is controlled by liquid meter and control device. The method is convenient to adjust the shift or load macroscopically, which reaches the request of microscopic operation and control.

Description

technical field [0001] The invention relates to a liquid-driven ultra-small displacement control device and a control method. Background technique [0002] The drive and control of load and displacement is a means widely used in various fields of engineering technology. With the development of science and technology and related industries, the drive and control technology from micro to nanoscale has become an urgent need and a field that attracts people's attention. One of the tasks of the drive and control of tiny loads or displacements is to control microscopic physical quantities or physical processes through macroscopic operations and adjustments; the methods and technical principles generally require corresponding accuracy, stability and reliability. In addition, the control range is required to be as large as possible, the operation is convenient, and the requirements for the working environment and conditions are reduced as much as possible. Rod mechanism, screw-nut...
