图1所示出油管接头是我厂加工的汽车构件离合器分泵中的一个零配件。由于其圆锥尺寸(?)5.5mm在零件的内部位置较深,形体较小,检测较困难。为了精确地测量,准确地加工,我们依据如下原理:锥体小端径向示值的大小一致性,可以转换为轴向示值的长短一致性,设计了如图2的检具。 Figure 1 shows the oil pipe fittings is processed in our factory car clutch clutch in a spare parts. Because of its conical size (?) 5.5mm in the parts of the internal location of the deeper, smaller body, testing more difficult. In order to accurately measure and accurately process, we are based on the following principle: the small end of the cone shows the size of the radial consistency can be converted to the length of the axial length of consistency, designed as in Figure 2 Gages.
