摘要：

基于USB总线技术与自复位光栅位移传感器开发了凸轮轴轮廓在位测量装置，对磨削后的凸轮轴进行了在位升程测量。介绍了测量原理及升程测量过程，采用“敏感点”法并结合三次均匀B样条拟合与最小二乘法对测量数据进行了处理，求解了凸轮升程的起始转角，获得了凸轮的实测升程。利用在位测量装置与BG1310-10型凸轮轮廓检测仪针对同一凸轮轴样件进行了对比检测实验。结果表明，该在位测量装置能够满足凸轮轴加工轮廓误差检测的精度要求。

Abstract:

An on-machine measurement device was proposed based on the USB bus technology and re-centering grating displacement sensor. Cam lift was measured directly on the grinding machine. The on-machine measuring principles and lift measuring process were studied. To solve the cam lift initial turning angle and get cam measured lift, the sensitive point method were used to process the measured lift data combining with cubic uniform B-spline interpolation fitting and least square method. A grinded camshaft was measured by the on-machine measurement device and BG1310-10 cam contour detector, and the measuring results were compared to confirm the validity of the proposed device.

Key words: camshaft, on-machine measurement, cubic uniform B-spline, lift fitting
