Abstract

The invention relates to the technical field of railway equipment. A manufacturing unit and a support unit are integrated onto the same supporting platform by utilizing a pair of engine bases. The locomotive wheel numerical control lathing device provided by the invention is characterized in that a tool supporting structure, a shaft end positioning device and a shaft end supporting device are arranged on the same platform base (1), the shaft end positioning device comprises a positioning bending plate (5) and a connection plate (6) which are provided with a positioning boss (2), a mounting bolt hole (3) and an axial clearance adjustment bolt (4), and a concentric stepped hole (7) is arranged in the positioning boss (2); the positioning bending plate (5) is lengthways fixed on the platform base (1) along the center line of the rounded positioning boss (2); the tool supporting structure is of an inclined plane (12) formed by forward extended one side of the front end of the platform base (1), wherein the inclined plane (12) is parallel to a plane formed by the axial line of the positioning boss (2) and the radius of a working point. The device is light in weight, simple in structure and operation, high in working efficiency, and low in investment cost, is applied to locomotive wheel lathing operation in a railway locomotive department, and is particularly applied to the wheel lathing operation without the wheel lathing condition.

Description

Technical field [0001] The invention belongs to the technical field of railway equipment, and relates to locomotive vehicle maintenance technology, in particular to the locomotive vehicle wheel set maintenance technology. Background technique [0002] As the running part of the rolling stock, the wear and tear of the wheel and track is inevitable. In order to ensure the safe operation of the rolling stock, it is very necessary to repair the wheel rim and tread in time according to the railway industry standard. Most of the existing repair equipment is to install a large fixed CNC non-falling wheel turning bed in the maintenance ditch of the locomotive and rolling stock. There is a movable track above the turning track, and axle box supporting devices and wheel set driving devices on both sides of the moving track. . When repairing, the locomotive drives to the top, and when the wheelset to be repaired travels directly above the processing tool, the axle box supporting devic...
