Flexible pre-stretching installation process

Abstract

The invention discloses a flexible pre-stretching installation process. The flexible pre-stretching installation process comprises a saddle fixed end finishing procedure, a saddle driven end finishingprocedure, a screw nut seat finishing procedure, a screw rod and saddle assembling procedure and a screw nut seat and a sliding plate clearance fit grinding procedure, wherein a sliding plate is arranged on a sliding block, a magnetic meter base is adsorbed on the sliding plate, a detection bar is installed on the end face matched with a saddle and the bearing block, the sliding plate is moved inthe direction of a guide rail, and whether side buses and the guide rails of the detection bar in the horizontal direction and the vertical direction are parallel or not by using a dial indicator, ifthe precision is not high, the end face of the saddle is scraped by a scraper, the parallelism degree of the detection bar and the guide rails meets the requirement, the perpendicularity of the mounting end surface of the bearing seat of the fixed end and the mounting end surface of the bearing seat of the driven end are finished in sequence, and a lead screw is pulled upwards in advance, so thatthe additional load of the side direction lead screw on the lead screw caused by the abrasion of the guide rails is effectively adapted, and the service life of the lead screw is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a deflection pre-stretching installation process. Background technique [0002] With the development of precision machine tools, higher and higher requirements are put forward for the accuracy and stability of machine tools. The linear motion accuracy of machine tools is guaranteed by ball guide rails and ball screws. The ball guide rail ensures the accuracy of the moving direction, and the ball screw ensures the accuracy of the moving distance. Although the existing screw installation process can achieve basic moving accuracy, it cannot adapt to the screw bearing and screw caused by the internal wear of the guide rail and the screw after long-term operation. Due to the extra load on the lead screw, the accuracy cannot be stabilized within a certain range for a long time. [0003] In order to solve the above problems, the present invention is proposed. Through simple...
