Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0013] like Figure 1 to Figure 3 The shown rolling stock wheel diameter measuring instrument comprises an arc-shaped frame 1 provided with a dial indicator 6, the measuring head 4 of the dial indicator 6 protrudes downward from the arc-shaped frame 1, and the center of the measuring head 4 of the dial indicator 6 The line coincides with the arc center line of the arc frame 1, and the two arc lower ends of the arc frame 1 are respectively symmetrically provided with measuring blocks 2, and an outer surface of the arc frame 1 is fixed with at least two end face positioning frames 3 by screws. The downward extensions of the two end face positioning frames 3 are connected with clamping blocks 5 with magnetic poles on the working surface; the two clamping blocks 5 are respectively fixed on the inner side of the downward extension of the end face positioning...

Abstract

The invention discloses a locomotive wheel diameter measuring instrument and relates to the technical field of manufacturing of detecting gauges. The locomotive wheel diameter measuring instrument comprises an arc-shaped framework provided with a dial indicator, wherein the measurement head of the dial indicator downwards stretches out of the arc-shaped framework, the center line of the measurement head of the dial indicator coincides with the arc-shaped center line of the arc-shaped framework, the two arc-shaped lower ends of the arc-shaped framework are symmetrically provided with measurement blocks, at least two end face positioning frames are arranged on one outer side face of the arc-shaped framework, and the end face positioning frames are connected with clamping blocks with work faces provided with magnetic poles. Compared with the prior art, the locomotive wheel diameter measuring instrument is simple in structure, small in size, light in weight, convenient to operate, capable of meeting the requirement for the measurement accuracy of the diameter of the rolling circle of a railway vehicle wheel, good in stability, capable of effectively guaranteeing the quality of the locomotive wheel and high in working efficiency, and meanwhile, labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of detection and inspection tool manufacturing, in particular to a measuring tool for measuring the rolling circle diameter of a railway vehicle wheel. Background technique [0002] The stable operation of the railway vehicle body is the premise and guarantee for the speed increase of the railway vehicle, and it is very important whether the wheel size of the railway vehicle meets the requirements of high precision. The current measurement of the rolling circle diameter of railway vehicle wheels is generally measured by using a wheel diameter ruler. The current use of a wheel diameter ruler to measure the wheel diameter of locomotives has the following shortcomings: sometimes the wheels are arranged continuously next to each other on the production line track, and the diameter It is very difficult to measure the diameter of the wheel with the measuring method measuring tool. Because the measuring space is ve...
