Precision adjusting device and method for ball screw assembly

Abstract

The invention discloses a precision adjusting device and method for a ball screw assembly, and the device and method achieve the precision adjustment of the ball screw assembly with a visual pattern through a laser autocollimator, an inclinometer and other electronic measurement devices. The precision adjusting device is mainly composed of a basic movement module, an installation and adjustment precision guaranteeing module and a control module. The basic movement module is used for matched installation and adjustment of the ball screw assembly, has a linear movement function and provides an installation environment for the installation and adjustment precision guarantee module. And the assembly and adjustment precision guarantee module is used for accurate measurement of form and location tolerance of matched assembly and adjustment of each component and high-precision assembly and adjustment guarantee of each component. And the control module is used for realizing the driving control and information measurement functions of electromechanical components in the ball screw assembly assembling and adjusting process. The precision adjusting method solves the problems of low precision, low efficiency and boring work of manual adjustment of the ball screw assembly, assists manual adjustment to be rapid and accurate, and improves the precision and efficiency of manual adjustment.

Description

technical field [0001] The invention relates to the field of robot mechanisms, in particular to the technical field of linear drive using ball screw assemblies in robot mechanisms, and in particular to a precision adjustment device and method for ball screw assemblies. Background technique [0002] In the fields of robotic mechanisms, repetitive locking mechanisms, etc., a large number of ball screw assemblies are used as transmission elements. , reversibility and high efficiency. A ball screw assembly usually consists of three parts, two linear slider guides and a ball screw. The assembly and adjustment process of the ball screw assembly not only needs to adjust the accuracy of the straightness and roll angle of the two linear slider guides and one ball screw respectively, but also needs to ensure the positional assembly relationship between the three parts. If these precision requirements cannot be met, the motion state of the ball screw assembly may be seriously affecte...
