Train wheel oil filler hole machining and positioning device and using method thereof

Abstract

The invention discloses a train wheel oil filler hole machining and positioning device. The device comprises a positioning base, a positioning ruler body and a marking pen; the positioning base is ofa platy structure, a penetrating hole is formed in the positioning base, the positioning ruler body is inserted into the penetrating hole, can move in the first direction and is fixed through a firstfastener after moving to a preset position, and the first direction is perpendicular to the positioning base; a positioning head is arranged at the end of the positioning ruler body, the marking pen is inserted into the positioning head, can move in the second direction and is fixed through a second fastener after moving to the preset position, and the second direction is perpendicular to the positioning ruler body. According to the train wheel oil filler hole machining positioning device, after the positions of the positioning ruler body and the marking pen are determined, the positioning base is placed on a hub face, then the positioning base is moved to mark out a marking line, and then positioning work can be completed; and operation is convenient, and efficiency is high. The positionsof the positioning ruler body and the marking pen can be conveniently adjusted to meet positioning of train wheel oil filler holes of different specifications, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of wheel processing auxiliary devices, in particular to a processing and positioning device for oil hole of a train wheel and a use method thereof. Background technique [0002] With the continuous increase in the speed and load of railway transport vehicles, higher requirements are placed on the quality of the running parts of the vehicles. As the direct support and load-bearing part of railway vehicles, the processing quality of railway track directly affects the safety and stability of railway transportation. [0003] In order to lubricate and cool the inside of the train wheel, it is necessary to process an oil injection hole on the inner wall of the train wheel hub to inject lubricating oil. In the prior art, when processing the oil hole of a freight train, the location of the oil hole is generally carried out in the following two ways: one is to use a depth gauge and a marking pen to coordinate positi...

Problems solved by technology

[0004] The inventor found that the existing technology has at least the following problems: the first positioning method can flexibly adjust the positioning according to the position requirements of the oil hole of different wheel products, but the actual operation is cumbersome, resulting in low efficiency and poor repeat positioning accuracy; the second positioning method is easy to operate The efficiency is high, but it is very inconvenient to adjust the positioning size when changing the processing type
