Measuring Coaxiality with Optoelectronic and Non-Contact Based on Helical Scanning
In view of the characteristic of the inefficiency on measuring coaxiality manually in industry, we put forward to studying on a laser triangulation san method for measuring distance to measure coaxiality. It takes relative motion between the measurement thing and displacement laser sensor to implement helical scan motion and gain the data of spiral scanning projection based on step servo system by gyration and the axial feed. This method can improve manufacture efficiency and achieve the demand of online automatic testing. Finally, the way of implementation of this system would be discussed in this paper, meanwhile, it would provide simulation results of the method and actually feasibility analysis .
