| 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1.72μm.

| Abstract: | Based 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 ... |
