【摘要】针对凸轮轴及曲轴测量的实际需要,设计了一种一维扫描测头,建立了测头的力学理论模型,并重点研究其核心部件平行片簧机构的受力变形理论,推导完善了平行片簧机构的变形公式定量分析了影响测头测量精度的因素,找出误差产生的根源以凸轮轴测量仪为实验平台完成了测头的性能实验,采用VDI-3441评价标准得到测头的重复定位误差为1.72 μm.osed on practical measuring requirement of camshaft and crankshaft, a specific one-dimensional scanning probe is designed and its mechanics theory model is established. As a research emphasis, the force deformation theory of parallel spring mechanism is investigated, and its deformation formula is derived and improved. The factors which have a quantitative effect on probe accuracy are discussed and the error sources are located. Finally, the VDI-3441 criterion is applied to evaluate the repetitive position error of probe. The testing result shows that its repetitive position error is within 1.72 μm.
