图1所示的测量装置可用于测定锥度大端和小端直径的偏差,在一定长度上锥度偏差的线性值,以及内锥孔两对称母线的直线性偏差。锥体7沿小端直径作成封闭的锥环(或锥盘)形,而沿大端直径作成圆柱表面,环6沿锥体轴线在圆柱面上移动。在锥体对称方向上开有两主要的纵向槽,在纵向槽中装有可移动的测头5,测头与直线样件4接触,样件4安
The measuring device shown in Fig. 1 can be used to determine the deviation of the taper large and small end diameters, the linearity of the taper deviation over a certain length, and the linearity deviation of the two symmetrical busbars of the inner cone. Cone 7 is formed in the form of a closed cone (or cone) along the diameter of the small end, while a cylindrical surface is formed along the diameter of the large end. Ring 6 moves along the axis of the cone on the cylindrical surface. In the symmetrical direction of the cone there are two main longitudinal grooves, in which the movable probe 5 is mounted, the probe being in contact with the linear sample 4, the sample 4 A
