为适应小批量生产的需要,笔者提出两种孔轴心线位置度误差简化测量方法。一、排列分布的孔在排列分布孔的情况下,与孔轴心线的位置公差是用尺寸公差来控制时,其公差带为矩形。这种标注是沿用了几十年的老方法,测量方便,检验人员也很熟悉。而位置度公差带为圆形,两者显然不一样。但作用是一样的,都是保证孔的位置正确。这就说明两者有共同的地方,下面来分析一下它们之间的联系。在位置度公差带圆φT中作一内接正方形,则正 In order to meet the needs of small batch production, the author proposed two kinds of hole axis position error simplification measurement method. First, the arrangement of the distribution of holes In the case of the distribution of holes, the position of the hole with the shaft axis tolerance is controlled by the dimensional tolerance, the tolerance band is rectangular. This label is followed by decades of old methods, easy to measure, inspectors are also very familiar. The location tolerance zone is circular, the two are obviously different. But the role is the same, are to ensure the correct location of holes. This shows that there is a common ground between the two, here’s an analysis of the connection between them. In the position tolerance with a circle φT for an inscribed square, then positive
