Embodiment Construction

[0025] In the biological coupling in nature, geometric coupling refers to the biological coupling with geometric structure in plane, space, macroscopic or microcosmic through one-dimensional, two-dimensional or three-dimensional geometric coupling between coupling elements. E.g. Chitons are mostly found in intertidal zones or shallow water in warm regions, and live in deep seas in colder regions. The body is oval, with a flat abdomen, symmetrical sides, and a central protrusion on the back with imbricate calcareous shell pieces. There are low-flat granular protrusions with a diameter of about 150 μm distributed inside the shell, longitudinal ribs are distributed on the peak of the middle shell, and there is a mantle around the shell, forming a wide ring, densely covered with finger-like protrusions, and white The needle bundles and chiton shells form extremely strong erosion and wear resistance through the coupling of these complex shapes, materials, and structures. Many org...

Abstract

The invention relates to a laser bionic coupling guide rail and a regeneration method thereof. Bionic surfaces different in abrasion resistance are machined in a slight abrasion area and a serious abrasion area on the working face of the guide rail. A point and strip bionic surface combining form or a strip and net bionic surface combining form or a point and net bionic surface combining form is adopted according to the hardness gradient or the stress gradient of the serious abrasion area and the slight abrasion area of the working face of the guide rail. A bionic surface with the overall abrasion resistance being consistent for a long term is formed through the combination of the bionic surfaces different in abrasion resistance, the mechanical performance of the surface with the uneven mechanical performance distribution can be recovered to be evenly distributed, the phenomenon of serious local abrasion caused by large local stress is effectively avoided, and the bionic coupling guide rail is more suitable for the angle of the actual work of the bionic coupling guide rail. A multi-bionic coupling surface combined uneven regeneration repairing manner is directly implemented on the local abrasion surface of a cast iron guide rail on which high-frequency quenching is carried out, and the problem that due to the uneven abrasion of the surface of the scraped guide rail, the scraped guide rail is hard to regenerate is basically solved.

Description

technical field [0001] The invention belongs to the technical field of regenerated cast iron guide rails, and relates to a laser bionic coupling guide rail combined with multiple bionic coupling surfaces and a regeneration method thereof. Background technique [0002] The machine tool guide rail is the guide part that supports the moving parts and ensures the movement accuracy, which directly affects the working accuracy of the machine tool. When there is relative motion between the rail surface and the load surface, if it is not a complete fluid friction, wear will inevitably occur. In the working direction of the tool mounted along the guide rail, multiple unequal feeds due to the different sizes of the processed workpieces will cause inconsistent local wear. If things go on like this, the guiding accuracy of the guide rail will gradually decrease, that is, the slide plate of the tool holder will be offset after the guide rail is worn. In the end, it will seriously affec...
