在一般机械加工工厂中,角度块是按级使用的,常用的是二级精度角度块。对于这种角度块的检定,在本厂没有专用检定设备、没有标准角度块的条件下,可以用下述方法自行检定。现把我厂过去采用过的一些检定方法,介绍给大家,供参考。1.间接测量法用正弦尺检查角度是大家熟悉的检查角度的方法(图1)。它的计算公式如下:sin α=H/L,式中α——为正弦尺工作面倾斜的角度;H——为所垫量块的高度;L——为正弦尺两滚柱轴线之间的距离。
In the general machining plant, the angle block is used by the level, commonly used is the two precision angle block. For the verification of this angle block, the factory does not have a dedicated verification equipment, there is no standard angle block conditions, you can use the following method of self-test. Now I plant used in the past some of the test methods introduced to you for reference. 1. Indirect measurement method Sine scale inspection angle is a familiar method of checking the angle (Figure 1). It is calculated as follows: sin α = H / L, where α is the angle of inclination of the sine scale face; H - is the height of the measuring block; L - is the sine bar between two roller axes distance.
