| In order to solve the problems of the contact measurement system of wire drawing dies,such as low precision,long response time.and the measurement parameter s can′t be collected,transmitted and processed in real time,the laser rotation method is innovatively introduced to measure the pass of wire drawing dies.The system is mainly composed of four parts of mechani cal part,optical imaging,data acquisition and network transmission.Diffraction patterns of circ les and ellipses are formed on CCD by rotating the center shaft of wire drawing dies continuously in the measurement process.The pass parameters of the wire drawing dies can be taken by using the f unction relation between the diffraction pattern and the rotation angle.At the same time,Internet plus is used to the system.Each wire drawing die is a node,and the network measurement system is for med by the networking technology.Thus,the real-time acquisition,analysis and processing of the measurement data for wire drawing dies are realized.Experiments show that the p recision of the measuring system can reach 0.01mm,and the system has high practical value in th e measurement of the drawing die pass. |
