在曲柄生产工艺中往往需要在杆部加工一定的孔或槽,用普通的检具很难准确检测其位置度。为此我们群策群力,实现了在万能工具显微镜上检测孔或槽的位置度。例如图1所示,技术要求:在杆部加工一318mm盲孔,且盲孔轴线与曲柄销孔轴线的夹角应小于0°±20′。图111心轴21曲柄31曲柄 In the crank production process often need to be processed in the shaft of a certain hole or groove, with an ordinary fixture is difficult to accurately detect the position degree. To this end we work together to achieve a universal tool microscope hole or slot position detection. For example, as shown in FIG. 1, the technical requirement is that a  318 mm blind hole is machined in the rod portion and the included angle between the axis of the blind hole and the axis of the crank pin should be less than 0 ° ± 20 ’.
