Research on precise measurement and scene-based algorithm for rolling linear guide rail profile based on line structured light
摘要
Abstract
In order to improve the manufacturing accuracy of the complex curved surface with small arc characteristics in the rolling linear guide pair,and ensure the service performance of the rolling functional components such as stiffness and friction torque,a precise and efficient measurement method of the rolling linear guide surface based on line structured light was proposed in this paper.Aiming at the unique scene of the guide rail profile,a set of point cloud fitting system of the improved scene algorithm was construct-ed,including the adaptive voxel filtering algorithm weighted by the raceway area,the PCA-K neighbor-hood inflection point identification algorithm with multi-feature fusion and the improved RANSAC arc fit-ting algorithm with adaptive radius constraint.Through the comparison experiment with the three-coordi-nate measuring machine and the image measuring instrument,it is verified that the measurement accuracy of the measurement system is better than 5 μm,which reaches the SP level measurement standard,and can realize the full contour detection of the guide rail surface.The measurement efficiency is more than 15 times higher than that of the three-coordinate measuring machine,which provides theoretical support and technical scheme for the high-precision and efficient detection of the rolling linear guide rail profile.关键词
