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
The present invention relates to detection tool manufacturing technology field, especially a kind of survey instrument for measuring railway car wheel rolling circle diameter.
Background technology
The stable operation of railroad car is prerequisite and the guarantee of rolling stock speed-raising, wherein railway car wheel size whether meet high-precision require most important.Existing measurement railway car wheel rolling circle diameter generally still uses wheel footpath chi to measure, existing employing wheel footpath chi carries out measurement wheel diameter of locomotive and exists following not enough: wheel is continuously arranged one by one on production line track sometimes, go measuring wheel footpath diameter very difficult with diameter measurement method measurer, because measurement space is very narrow and small, conventional measurer does not go with under this, operation extremely bothers, and it is too low to measure efficiency, measuring accuracy is difficult to be protected, and cannot ensure locomotive wheel quality.
Summary of the invention
The object of this invention is to provide a kind of rolling stock wheel cable diameter gauge, it is inconvenient that it can solve existing locomotive car wheel outside diameter measuring, and inefficiency, cannot ensure the problem of locomotive wheel quality.
In order to solve the problem, the technical solution used in the present invention is: comprise the arc framework being provided with dial gauge, the measuring head of described dial gauge stretches out described arc framework downwards, the center line of described dial indicator measuring head overlaps with the arc center line of described arc framework, survey mass is arranged with respectively in described arc framework two arc lower end, one lateral surface of described arc framework is provided with at least two end face locating racks, and described end face locating rack is connected with the fixture block that workplace is provided with magnetic pole.
In the technical scheme of above-mentioned rolling stock wheel cable diameter gauge, technical scheme can also be more specifically: two pieces of described fixture blocks are separately fixed at the inner side of described end face locating rack, and the workplace of two pieces of described survey mass is arranged down.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to have employed, survey mass is set at arc framework two ends, well find measuring basis, be connected on the tread at wheel rim top of wheel to be measured downwards by the measuring head of the dial gauge on arc framework, two pieces of survey mass are connected to symmetrical 2 points of the measuring head of dial gauge on wheel rim tread to be measured, the survey mass at two ends and the measuring head of dial gauge is made to form 3 reverse V-shaped points, whole wheel rim external diameter is calculated according to the reader of dial gauge, the measurement range of whole survey instrument is without the need to being greater than wheel rim diameter, light and flexible, simple to operate, measurement efficiency is high, measuring accuracy meets the requirements,
2, structure is simple, volume is little, only needs wheel to have the circumference of 90 degree, just can measure diameter, solves diameter measurement method measurer on production line track and the narrow and small place of measurement space cannot be measured, a difficult problem for bad measurement.

Fig. 1 is the front view of embodiments of the invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A direction view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Rolling stock wheel's cable diameter gauge as shown in Figure 1 to Figure 3, comprise the arc framework 1 being provided with dial gauge 6, the measuring head 4 of dial gauge 6 stretches out arc framework 1 downwards, the center line of the measuring head 4 of dial gauge 6 overlaps with the arc center line of arc framework 1, arc framework 1 liang of arc lower end is arranged with survey mass 2 respectively, one lateral surface of arc framework 1 is fixed with at least two end face locating racks 3 by screw, is connected with the fixture block 5 that workplace is provided with magnetic pole at two end face locating racks 3 to lower extension; Two pieces of fixture blocks 5 are respectively by being bolted to the inner side of end face locating rack 3 to lower extension, and the workplace of two pieces of survey mass 2 is obliquely installed down, and its pitch angle is determined by measurement requirement design; Be provided with multiple through hole in the plate face of this arc framework 1, be convenient to workman and measure operation.
During work, first be placed on standard round by the present invention, ensure that two pieces of survey mass 2 all contact well with standard round cambered surface, it is closely connected that end face locating rack 3 and standard round locate end face, then by moving up and down the dial plate of dial gauge 6 and rotation dial gauge 6, dial gauge 6 is transferred to standard round diameter value.During measurement, the through hole that the plate face that operator two holds arc framework 1 is provided with, the present invention is placed on tested wheel 7, the fixture block 5 with magnetic pole of two end face locating racks 3 is made to be close to closely connected with wheel 7 medial surface, then two have gentle hands are gently pressed, all contact with wheel tread 8 to two pieces of survey mass 2 and put in place, at this moment can read wheel diameter numerical value from dial gauge 6.Structure of the present invention is simple, lightweight, easy to operate, meet the requirement of rail vehicles wheel rolling circular diameter measuring accuracy, good stability, effectively can ensure the outer path quality of locomotive wheel, improve work efficiency high, reduce labour intensity, solve diameter measurement method measurer on production line track and the narrow and small place of measurement space cannot be measured, a difficult problem for bad measurement.
