Description

Technical Field

[0001] The utility model relates to an inspection tool and belongs to the field of rail processing. Background Art

[0002] By strengthening the top surface and the inner side surface of the rail with high temperature plasma, the hardness can reach above RHC60, which increases the wear resistance of the rail and prolongs the service life of the rail. When strengthening the top surface and the inner side surface of the rail with high temperature plasma, the treatment is carried out along the length direction of the rail. After strengthening the top surface and the inner side surface of the rail with high temperature plasma, the position of the spots strengthened by high temperature plasma needs to be checked. At present, there is no tooling for checking whether there are errors in the position of the spots produced by high temperature plasma on the rail, which makes the spot inspection difficult.
