Study of Control and Measurement System for Precision Straightening Machine
The paper researches the soft-hardware composing and the control and determination of the straightening quantity. The system adopts the master-slave structure that PC is used as the main control computer and PLC and controller is used as the executive computer. The determination of the bend quantity is to measure a spot of shaft sections. The numeric approach is used to calculate the maximum curvature, and then confirm the position. Last exactly estimate the maximal distortion and bend location. The control of the straightening quantity is that the pressure head position is measured by the raster displacement sensor and the electro-liquid position servo control system finishes the precise control. The paper establishes the mathematical modal of the hydraulic position servo system. And using MATLAB software executes the system analysis, simulation and adjustment. Through the test the straightening precision reaches to ±2.5μm once. The system is satisfied with the request.
