大多数圆锥体(内或外)锥角的测量方法往往较麻烦,常需要平板,尺寸正确的轴承钢球及一些不常备有的测量工具。这里介绍的方法仅需一件精度较高的标准游标卡尺和一对长度和直径已知的圆形测杆即可。图示,选用两件长度相同、直径分别为9.529毫米和6.350毫米的圆形测杆,测杆端面用砂纸轻轻擦净,注意保持锐边,端面边缘处不得有裂口。按图把测杆分别插入工件锥孔里,记下不同的穿入深度(此
Most cone (inside or outside) taper angle measurement methods are often more troublesome, often require the plate, the correct size of the bearing ball and some not equipped with measuring tools. The method described here requires only one standard vernier caliper and one pair of circular rods of known length and diameter. For illustration, select two circular measuring rods with the same length and diameter of 9.529mm and 6.350mm respectively. Wipe the end of the measuring rod with sandpaper gently, keep the sharp edges and avoid any rift at the edge of the end surface. According to the figure to the test rod into the workpiece taper hole, note the different penetration depth (this
