在用水平仪测量导轨的直线度误差时,一般是按水平仪的读数,采用作图法或计算法来求得直线度误差。但作图法需座标纸,而计算法需繁琐的计算,在现场使用时就不甚方便。我们在作图法的基础上设计制造的直线度误差计算尺基本上解决了上述问题。现将其结构、使用方法介绍如下:一、直线度误差计算尺的结构:直线度误差计算尺的结构如图1所示。尺体①上有12个凹槽,分别配有滑尺②,滑尺可沿尺体凹槽左右滑动。转轴(11)上有转动板④,
When using the spirit level to measure the straightness error of the guideway, it is generally to obtain the straightness error by the drawing method or the calculation method according to the reading of the level instrument. However, the mapping method needs coordinate paper, and the calculation method needs cumbersome calculation, which is inconvenient when used in the field. We design and manufacture on the basis of the drawing method straightness error scale basically solved the above problems. Now its structure, the use of methods described below: First, the straightness error calculation ruler structure: Straightness error calculation ruler structure shown in Figure 1. There are 12 grooves on the ruler ①, each equipped with a slide ②, the slide along the ruler groove can slide around. Rotary shaft (11) has a rotating plate ④,
