Description

Positioning and calibrating tool for laser cladding of jack Technical Field The utility model belongs to the field of laser cladding equipment, and particularly relates to a positioning and calibrating tool for laser cladding of a jack. Background Laser cladding is a process in which cladding material is added to the surface of a substrate and fused with a thin layer of the substrate surface using a high energy density laser beam. When cladding is carried out on shaft workpieces, one end of a roller body is generally clamped and fixed by clamping equipment, the roller body is supported by two supporting wheels at the middle part, the roller body types are different, the diameters of the roller body types are different, and the supporting wheels are required to be adjusted at the moment. The existing positioning calibration fixture can only adjust the distance between the supporting wheels and the whole height, but after long-time operation, the existing positioning calibration fixture still has small height difference between different supporting wheels after the whole height adjustment due to equipment abrasion, part looseness and other reasons, the existing calibration fixture cannot adjust a single supporting wheel, the supporting heights on two sides of a roller are unbalanced easily, and the cladding quality is affected.
