Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and relates to a rail milling cutter blade replacement device, and in particular to a rail milling cutter blade replacement device and an inspection method. Background Art

[0002] Rail milling cutters are mainly used to perform precise milling on rails to restore or improve the profile accuracy and surface quality of the rails.

[0003] Rail milling cutters are often equipped with multiple tool holders, and multiple milling blades are arranged on the tool holders. Compared with traditional integrated milling cutters, milling blades have multiple cutting edges that can be used, and are easier to disassemble and maintain. Since the rails are multi-arc structures, the milling blades need to be installed with a special structure. Through the combination of multiple sets of milling blades, the cutting contour can be made to conform to the shape of the rails.

[0004] Since the processing environment is relatively complex outdoors, the milling cutters will be damaged to varying degrees. The traditional method is to determine whether the milling cutters need to be replaced by inspecting the surface of the rails and manually screening and replacing them. This requires more personnel to operate, so it is necessary to develop equipment to simplify the replacement of milling cutters. Summary of the invention

[0005] The purpose of the present invention is to provide a rail milling cutter blade replacement device and inspection method which is easy to operate and automatically operated in order to solve the above problems existing in the prior art.
