摘要
基于激光位移传感器测距原理,利用精密转台和轴向进给的步进伺服执行机构,带动转台上的被测件与激光位移传感器作相对运动的旋转,实现螺旋扫描运动。采用螺旋线投影法测量出被测物体的同轴度,实现了提高检测效率和在线自动化检测的要求。仿真验证了该测量方法的可行性。
A laser triangulation scan method for measuring distance was studied.The aim of relative motion between the measurement object and micro-displacement laser sensor was to implement helical scan motion,and the method of spiral scanning projection to measure coaxality,according to step servo system by gyration and the axial feed,was used.It could improve manufacture efficiency and achieve the demand of online automatic testing.The system and the method of measuring was introduced,and the simulation results of ...
