摘要
介绍一种大型机械零部件孔用同轴度测量系统。系统采用单模光纤的尾纤半导体激光器作光源的激光准直系统 ,并为测量提供稳定的基准线。同轴度由多个截面的光斑中心坐标值和圆周采样数据按一定的方法计算。
A new coaxiality measuring system for holes of large scale mechanical parts is introduced. A single mode fiber(SMF) pigtailed laser diode alignment system provides a laser reference line with fine stability for measurement. The coaxiality is computed from the measured coordinates of laser spot center and measured circumference data in several sections of holes.
