Auxiliary process shaft used for spraying paint on wheels of railway vehicles

Abstract

The invention belongs to the field of auxiliary devices for spraying paint on wheels of railway vehicles and discloses an auxiliary process shaft used for spraying paint on wheels of railway vehicles. According to the auxiliary process shaft, a wheel positioning mechanism with opposite conical slopes is used for axially positioning a naked piece of a novel wheel with a noise reduction ring in a rolling mode, so that the rapid and even paint spraying procedure of the naked piece of the novel wheel is completed through an existing mature paint spraying chamber device, the tedious and complex procedures such as paint spraying protection of components like brake discs and noise reduction rings are avoided, and furthermore, reconstitution and optimization design of the technological process are achieved. In addition, the auxiliary process shaft used for spraying paint on wheels of railway vehicles has the advantages of being simple and practical in structure, convenient to assemble and disassemble, low in cost, convenient to popularize and the like.

Description

technical field [0001] The invention belongs to the field of rail vehicle wheel painting auxiliary devices, in particular to an auxiliary process shaft for rail vehicle wheel painting. Background technique [0002] Domestic old conventional rail vehicle wheel sets such as figure 1 As shown, it consists of two conventional wheels 8 fixedly connected to the two ends of the standard axle 7 respectively and integrally forming a conventional wheel set. The conventional wheel set composition can be integrated into the existing wheel set spray booth, and the standard axle 7 is driven by the transmission device to realize self-axis rotation, and the entire wheel set composition completes the overall painting process during this rotation process. The paint spraying process can realize spray paint protection on all exposed outer surfaces of the conventional wheel 8 . However, the existing wheel set paint booth can only be used for figure 1 The shown conventional wheelset compositio...

AI Technical Summary

Problems solved by technology

[0014] In order to solve the problem that the existing standard axles cannot be directly applied to the separate painting process of the new wheel bare parts in the spray booth, resulting in idle production capacity of resource equipment in the spray booth, and once the old standard axles are assembled with the new wheel bare parts to form a wheel set Composition, it is difficult to separate the two again, which will cause interference and inconvenience to the assembly steps of further installing the noise reduction ring and the brake disc on the bare parts of the new wheel, and the increased assembly and assembly of the new wheel and the standard axle The unloading link seriously affects the production progress, and it is easy to cause the technical problem of scrapping the standard axle or the new wheel. The invention provides an auxiliary process axle for rail vehicle wheel painting.
