非整圆的零件,如果要测量它的直径尺寸是有困难的,测量方法虽然很多,但都要用仪器或专用量具,下面介绍两种比较简单的测量方法:一、靠圆柱直接测量法(如图1):测量是在直角铁5和标准圆柱 1帮助下完成的。被测工件4沿圆柱1绕中心O旋转。两圆柱体通过压板3、螺栓7和螺母2并列固定在直角铁5上。测量时,首先将工件5向下转动,使端面转过中心线M—M—些,用高度尺及杠杆指示表测量圆
Non-round parts, if it is difficult to measure the size of its diameter, although a lot of measurement methods, but to use instruments or special measuring tools, the following two simple measurement methods: First, by direct measurement of the cylinder method ( Figure 1): The measurements were made with the help of a right angle iron 5 and a standard cylinder 1. The workpiece 4 is rotated around the center 1 along the cylinder 1. Two cylinder through the platen 3, bolt 7 and nut 2 side by side fixed on the right angle iron 5. Measurement, the first workpiece 5 will be rotated down, so that the end turned around the center line M-M-, with a height gauge and lever indicator measuring circle
