Description

一种半径检测尺
技术领域
本实用新型涉及一种测量工具,尤其涉及一种半径检测尺。
背景技术
在机械制造和检验中,经常会碰到工件非整圆的圆弧面的半径的测量问题,在现有技术中测量圆弧半径的方法主要有:圆弧样板测量法、卡尺法和弓弦法,基于这几种测量方法设计的测量装置都存在局限和不足,不能满足在生产现场直接、方便、准确地检测这类零件圆弧的半径的要求。
实用新型内容
本实用新型所要解决的技术问题是提供一种半径检测尺,能够直接获得工件非整圆的圆弧面的半径值。
为解决上述技术问题,本实用新型的技术方案为:由一个弹性尺和两个刻度尺组成,所述两个刻度尺相互保持间距、长度方向与所述弹性尺尺面垂直固定在该弹性尺尺面上,所述刻度尺至少一个上有长度刻度。
优选的,所述弹性尺由薄钢片组成,所述刻度尺上均有长度刻度。
本实用新型的有益效果是,弹性尺可以弯曲,测量时将弹性尺紧贴于工件圆弧面,根据平面几何原理,“圆周上任何一条法线均经过圆心”,两刻度尺之交点就是圆心,刻度尺上读数即为该工件圆弧面的半径,可以测定工件的内外径,本实用新型结构简单,能够直接、方便、准确地检测工件内外圆弧的半径。
附图说明
图1是半径检测尺的结构示意图,图2是半径检测尺的使用状态图。
图中:1-弹性尺;2-刻度尺I;3-刻度尺II。
具体实施方式
如图1所示,本半径检测尺由弹性尺1和刻度尺I2、刻度尺II3组成,弹性尺1由薄钢片组成,可以弯曲,刻度尺I2和刻度尺II3相互分开距离、长度方向与弹性尺1尺面垂直焊接在该弹性尺尺面上,刻度尺I2、刻度尺II3上均有长度刻度,可精确至0.5mm,用于测定工件的内外径。本半径检测尺的弹性尺1的宽度、刻度尺I2和刻度尺II3的长度、间距、刻度精度可按测量类别等不同要求制造,可做成系列产品。
