Method for Adjusting the Installation Accuracy of Rack Guideway Assembly
Rack guideway assembly has high installation accuracy requirements,and the adjustment method mainly depends on experience.The relationship between adjusting screw tightening torque and guideway displacement is not clear,so the method of adjusting rack guideway assembly installation accuracy is studied to explore the relationship between adjusting screw tightening torque and guideway displacement,so as to improve assembly accuracy and ensure product quality.Based on the singular function,the relationship be-tween the tightening torque of adjusting screw and the displacement of guideway was established.The ge-netic algorithm was used to optimize the tightening torque of screws at specific positions,and a method for adjusting the straightness and parallelism of rack guideway assembly was formed.The feasibility of the ad-justment method was verified by finite element simulation.The results show that the method can solve the adjusting screw torque of the corresponding position according to the offset of the guide rail,reduce the blindness of the guideway adjustment,reduce the straightness and parallelism errors of the guideway instal-lation,and improve the installation accuracy of the linear guideway.
