Machining cutter for assembling retaining ring on haulage motor split wheel set

Abstract

The invention provides a machining cutter for assembling a retaining ring on a haulage motor split wheel set. The machining cutter is composed of a cutter body, a cutter point, a lower positioning plate and an upper limiting plate, and one side face in the length direction of the cutter body inclines in an arc mode by a certain distance inwards and then horizontally extends to form the cutter point. The upper limiting plate is vertically fixed to the portion, inclining in the arc mode, of the side face, the contact parts of the side face and the upper limiting plate are aligned, the lower positioning plate is fixed to the cutter body surface surrounded by the side face and the upper limiting plate in the length direction and is wider than the upper limiting plate. A strake of the haulage motor split wheel set can be directly machined without being disassembled, and potential quality hazards caused by disassembling the strake and assembling the retaining ring are avoided.

Description

technical field [0001] The invention belongs to the technical field of wheel set processing, and in particular relates to a processing tool for attaching buckles to split wheel sets of locomotives. Background technique [0002] In the early stage, some domestic locomotive split wheel sets such as DF8B and DF12 had no buckle rings, but since 2014, the Railway Corporation requires all locomotive split wheel sets to be equipped with buckle rings, otherwise the locomotive is not allowed to go online. [0003] Therefore, all split wheelsets without buckles are now required to install buckles. [0004] Current state of technology: [0005] 1. When installing the buckle according to the normal process, it is necessary to disassemble the tire first, then process the buckle groove on the tire, and then assemble the tire and the buckle. However, after the tire is disassembled, there may be situations where the inner hole of the tire or the outer circle of the wheel center rim is def...

AI Technical Summary

Problems solved by technology

However, after the tire is disassembled, the inner hole of the tire or the outer circle of the wheel center rim may be deformed and cannot be used. In this case, the wheel center needs to be disassembled, and there is a risk of straining the axle when the wheel center is disassembled.

Therefore, dismantling the tire and installing the buckle to store the larger quality analysis and unpredictable economic loss

[0006] 2. If it is not disassembled, it can be processed directly. Since there is a driven gear on one side of the wheel set, interference will occur during normal tool processing, so it cannot be processed
