一种刀口形直尺检定装置的设计与研究

Design and Research of a Straight Edge Verification Device

现有刀口形直尺检定规程的工作棱边直线度检定方法为比较测量法,无法将直线度进行量化,存在人员测量误差较大且检测效率不高等问题。为提高刀口形直尺计量检定的准确性及效率,本次研究以高精度轮廓仪为基础,研制了专用测头及夹具,设计了一套刀口形直尺棱边直线度计量检定方法,以实现直线度量化及综合评定。

The straightness of the working edge of the existing verification procedures of knife-edge ruler cannot be quantified because of the comparative measurement method,resulting in large measurement errors and low detection efficiency.In order to improve the accuracy and efficiency of the measurement verification of knife-edge ruler,this study developed a special probe and fixture based on the high-precision profilometer,and designed a set of measurement verification method of edge straightness of knife-edge ruler,so as to realize the quantification and comprehensive evaluation of straightness.
