如图1所示泵体,要求准确测量φ13H7孔和φ9H7孔的距离12_(+0.02)~(+0.09)mm。因两孔相互垂直,一般方法难以检测,图2所示是我们为此专门设计的检具。
Figure 1 shows the pump body, requiring accurate measurement of φ13H7 hole and φ9H7 hole distance 12 _ (+0.02) ~ (+0.09) mm. Due to the two holes perpendicular to each other, the general method is difficult to detect, Figure 2 shows that we specifically designed for the fixture.
