Design Of 3-meters Ball Screw Helix Error Measurement System Based On Laser

As important functional part, helix precision of high precision ball screw unit lays a great effect on the one of CNC.Combining with engineeral project "3-meters ball screw dynamic laser measurer of Shandong Jining Best Inc.", This subject conducts a sturctural an designal improvement on the origin device to enhance its modernization and intelligence.This paper firstly studies the measuring method, chooses the basic dynamic measuring way, and makes a whole improvement project on current situation of measure device. The device takes high precision cycle light sheet as angle measuring standard, Renishaw ML10 laser as lengthtude measuring standard, temperature supplying system designed by self as part of a whole project.According to ball screw spiral accuracy criterial standard, measuring software with well human-machine interaction and qualified to measuring requests is developed to go along the automechnical and intelligence trendCheck on the accuracy of measuring instrument and analysis on the factor of measuring error does some preparation for further improvement of the measuring precision.The subject completed the technical improvement on 3-meters measuring device with great partitioned application value.
