A partition construction bionic coupling surface repair waste machine tool guide rail and its method

Abstract

The invention relates to a zone building bionic coupling surface repairing waste machine tool guide rail. The surface of the guide rail is divided into three zones including a zone A, a zone B and a zone C from big to small according to the hardness obtained before repairing; strip bionic coupling elements, dot and strip combined bionic coupling elements and net bionic coupling elements are machined on the surface of the zone A, the surface of the zone B and the surface of the zone C correspondingly; and each zone is divided into a plurality of fine adjustment zones according to the hardness obtained before repairing, the fine adjustment zones are changed from big to small along with changes of the hardness obtained before repairing, and the distances of the coupling elements on the zones are changed from small to big. According to the zone building bionic coupling surface repairing waste machine tool guide rail, corresponding bionic coupling models are matched with the surfaces of the different hardness zones of the guide rail, the problem about uniformity during non-uniform repairing is solved, and the working years of a repaired machine tool can reach even exceed the working years of a new machine tool; and the service life of the repaired guide rail can reach 8 years to 12 years, the using years of the guide rail and the machine tool are greatly prolonged, scraping of the overall machine tool is avoided, resources wasted for manufacturing the new machine tool are saved, and a large number of resources are saved.

Description

Technical field [0001] The invention belongs to the field of repair and regeneration of waste machine tool guide rails, and relates to a method for uniformly repairing waste machine tool guide rails with non-uniform wear degree by using a laser processing method to construct a bionic coupling surface in sections. Background technique [0002] Machine tool guide rails are used to support and guide components to move along a certain trajectory or to clamp and locate on the machine tool. The conventional damaged parts of the machine tool can be replaced, and for the machine tool where the guide rail and the bed are connected as a whole, when the guide rail is severely worn to scrap, it means the entire machine tool is scrapped, resulting in a great waste of resources. If the discarded guide rails are repaired and regenerated, the service life of the entire machine tool can be effectively extended and a lot of resources can be saved. However, rails with hardened surfaces often leave...

Problems solved by technology

The first method is to divide the surface of the guide rail into a severely worn area and a slightly worn area in the feed direction of the tool that is mounted on it during actual work along the guide rail, and use lasers to process and couple different shapes in the two areas with different degrees of wear. The bionic surface of the bionic unit body, and then obtain the guide rail surface combined with multiple bionic coupling surfaces with uniform hardness and stress distribution, and the wear resistance tends to be uniform, to realize its regeneration; this method only divides the hardness difference into two areas, and does not consider The hardness value of the interval is different, so there is still the problem of uneven anti-wear performance in each interval after repair

The second method designs two specific double-coupling-element biomimetic surfaces with varying spacings based on the hardness or stress distribution in areas of different wear degrees. Multi-factor and multi-structure mutual coupling and interactive coupling bionic areas to improve the wear resistance of the sliding guide rail; the disadvantage of this method is that the double coupling element bionic unit bodies in each hardness difference interval have the same spacing, so each There is also the problem of uneven anti-wear performance in the interval
