前言凸轮轴检测,是汽车,拖拉机和内燃机等行业的一个重要检测项目。在我国,由于缺乏专用量仪检测凸轮轴,目前仍采用通用光学分度头及线纹尺阿贝头,由人工逐点地进行静态测量。这样,不作数据处理仅测量凸轮轴上2～3片凸轮的升程曲线,就需要3个人工作半天至一天的时间,不仅工效低而且劳动强度大。由于上述原因,凸轮轴加工,目前抽查率很低,一 Preface Camshaft testing is an important test item for the automotive, tractor and internal combustion engine industries. In our country, due to the lack of special measuring instrument for measuring camshafts, the common optical indexing head and line ruler Abbe head are still used, and the static measurement is carried out point by point manually. In this way, no data processing only measure the camshaft 2 to 3 cam lift curve, you need three people working half a day to a day, not only low efficiency and labor-intensive. Due to the above reasons, camshaft processing, the current sampling rate is very low, one
