Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The laser residual thermal deformation correction method for the track deformation of the split arc rolling guide rail of the present invention, the specific process is: the arc opening becomes larger, the inner wall of the arc track is scanned with a laser, the arc opening becomes smaller, and the outer wall of the arc track is scanned with a laser ;The laser power can change the metallographic structure of the track wall; the laser power will not cause excessive opening deformation; for the overall opening deformation of the track, if the surface is continuously irradiated with the laser, the heat energy distribution obtained on the surface is small at both ends and large at the middle; constant, the speed of the laser beam scanning the surface changes, the speed at both ends of the track is fast, and the middle is slow, so that the h...

Abstract

The invention discloses a laser residual thermal deformation correction method for track deformation of a split arc rolling guide rail. Laser irradiates the arc surface of the track, the surface metallographic structure is changed, surface stress is generated, the shape of the arc track is changed, and then the roundness of the track is changed.

Description

technical field [0001] The invention belongs to the technical field of split arc rolling guide rail structures, and relates to a method for correcting laser residual thermal deformation of track deformation of split arc rolling guide rails. Background technique [0002] The split arc rolling guide is a new type of rolling guide. The track of the guide is arc-shaped. When in use, multiple arc tracks can be spliced ​​into a complete circle. The slider on the track can move along the guide rail in a circular arc. [0003] As the shape of the split arc track is not a complete circle, but a segmented circle, compared with the shape of a full circle, it is easier to produce structural deformation after heat treatment or machining, resulting in a roundness error exceeding Difference. Even if the roundness error of the arc-shaped track meets the requirements after heat treatment or machining, as the use time increases, the internal stress of the structure will gradually release, an...
