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...
