Document Type and Number:
WIPO Patent Application WO/2024/078291
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and device for repairing damage on a mounting surface of an axle box body. The method comprises the following steps: acquiring a size measurement result of a corrosion pit at a damaged position of a mounting surface of an axle box body to determine defect areas of the damaged position, and removing corrosion layers of the defect areas by using subtractive processing treatment; performing classification on the defect areas, and correspondingly spraying the defect areas on the basis of the types of the defect areas to obtain corresponding repair areas; and performing subtractive remanufacturing on each repair area to restore the size of the mounting surface. According to the method, corrosion products on the mounting surface of the axle box body can be removed, the size of the axle box body can be efficiently and accurately restored by performing additive treatment and substrative treatment in sequence on the basis of removing the corrosion products by machining, the influence of a conventional thermal repairing means on the structure state, the size precision and the mechanical property of parts is eliminated, and the service life of the axle box body is further prolonged.
