在车间条件下,用正弦尺、圆柱等辅助量具,精密测量锥体尺寸的方法有下列几种。一、内圆锥体尺寸的测量 1.锥度的测量。测量方法如图1a、b所示。量块尺寸h按锥体圆锥半角的公称值计算即h=L·sinα圆锥角的实际偏差△2α,即是锥体上下两 In the workshop conditions, the use of sine ruler, cylinder and other auxiliary measuring tools, precision measurement cone size methods are the following. First, the measurement of the inner cone size 1. Taper measurement. The measurement method is shown in Figure 1a, b. The amount of block size h according to the cone conical half-angle nominal value that h = L · sinα cone angle of the actual deviation △ 2α, that is, the cone up and down two
