随着我国汽车工业的蓬勃发展，发动机的核心部件凸轮轴已广泛采用生产自动线，而其精度的检测则必须配套高效率的凸轮轴自动测量仪，并配以快速的数据处理及打印功能。传统的光学分度头及凸轮测量附件效率极低，并需要人工数据计算，不能适应生产需要。我们根据现有国内外凸轮 With the rapid development of China’s automobile industry, the camshaft of the engine has been widely used automatic production line, and its accuracy testing must be accompanied by efficient camshaft automatic measuring instrument, coupled with fast data processing and printing capabilities. Traditional optical indexing heads and cam measurement attachments are extremely inefficient and require manual data calculations that can not be adapted to production needs. We based on the existing cam at home and abroad
