在机械加工中,经常遇到对比较浅的内外圆止口、凸凹台和孔距等一些工件的测量,有些工件的公差小、精度要求高,由于这些工件的测量面比较浅,内径表及千分尺无法测量。用卡尺测量,精度不易达到公差要求。为了提高测量的精确度,保证工件的公差要求,我们利用一个10～18毫米的内径百分表和一把300毫米的废卡尺,制成了一把可以测量内外尺寸的组合量具。经过半年来的实践证明,效果良好,现介绍如下。
In machining, we often encounter relatively shallow internal and external circular stop, convex and concave table and some other parts of the hole distance measurement, some of the small tolerances, high precision, due to the relatively shallow measurement of these parts, the inner diameter of the table and Micrometer can not be measured. Caliper measurement, accuracy is not easy to achieve tolerance requirements. In order to improve the accuracy of the measurement and to ensure the tolerance of the workpieces, we used a 10-18 mm diameter dial indicator and a 300mm caliper to make a combination measuring tool that can measure the inside and outside dimensions. After six months of practice has proved that the effect is good, are presented below.
