我车间在生产图1所示零件时,图样要求在圆柱面上加工一斜孔。由于该孔在圆柱面上,且孔上表面(图1中M面)与下表面(图1中D面)的相互位置错移很大,因而用三用卡尺或量块测量尺寸10±0.15mm时,测量基准不易找谁,误差很大,很难判定尺寸合格与否。为此,我们设计了图2所示测具,能准确判定尺寸10±0.15mm是否合格。 My workshop in the production of parts shown in Figure 1, the drawings require a cylindrical hole in the processing of a hole. As the hole in the cylindrical surface, and the hole on the surface (M surface in Figure 1) and the lower surface (D surface in Figure 1) the mutual misalignment is very large, so with a three caliper or measuring the size of 10 ± 0.15 mm, it is not easy to find the measurement base, the error is very large, it is difficult to judge the size of the pass or not. To this end, we designed the tool shown in Figure 2, can accurately determine the size of 10 ± 0.15mm qualified.
