精密凸轮轴非接触测量仪设计
摘要：凸轮轴测量仪采用精密机械、光栅、微型计算机等技术，为满足汽车、摩托车发动机凸轮轴、汽车前后桥刹车凸轮轴等检测要求而特殊设计制造的新型测量仪器，可测量凸轮轴的桃形型而误差、桃形对定位键槽的相位角误差、桃形间相位角误差、轴径的径向跳动及凸轮的速度、加速度等测量项目。仪器采用通用微机系统进行测量循环控制、测量数据采集处理以及测量误差评值和测量结果输出。最大凸轮轴测量长度可达1.5米。
非接触式测量是指不接触被测物体的前提下进行精准测量。其测量精度可以达到μm非接触式测量仪利用CCD采集变焦镜下样品的影像,再配合XYZ轴移动平台及自动变焦镜，运用影像分析原理，通过计算机处理影像信号，对科研生产零件进行精密的几何数据的测量，并可进行CPK数值的分析。
