Description

Technical Field

[0001] The invention relates to the technical field of component detection, adjustment and installation, and in particular to a rapid detection and adjustment device and an adjustment method for a long-span ball screw. Background Art

[0002] In actual applications, ball screw installation often relies on manpower. For ball screws with longer dimensions and larger radii, installation is more difficult, mainly because the ball screw itself is heavy, and manual assembly often results in large precision errors. During installation, electrical equipment must be coordinated and parts must be repeatedly disassembled and assembled to adjust the ball screw. The precise positioning and installation of the screw plays a key role in the normal operation of the equipment. If the installation of the screw's busbar is bent and deformed, it will not only reduce the screw's operating accuracy and increase the transmission wear, but also increase the motor's drive load, resulting in increased energy consumption and greatly shortening the service life of the ball screw and motor.

[0003] Based on this, a rapid detection and adjustment device and adjustment method for a long-span ball screw are proposed, which can not only ensure the installation accuracy of the ball screw, but also have high installation efficiency and save a lot of labor costs. Summary of the invention
