Description
Technical field
The present invention relates to a kind of locomotive axle box health check-up and survey device and method, belong to railway locomotive manufacturing technology field.
Background technology
The structure of locomotive axle casing is shown in accompanying drawing 1, during its processing and manufacturing, needs measurement endoporus center to drawing
Spacing dimension A1 and A2 in pole socket face.But this center, hole is really a non-physical empty measurement point, as
What realizes that the measurement of this size is technological difficulties.
A kind of method of the prior art is to utilize large-scale vernier micrometer to coordinate clamp to measure.This survey
Amount mode is first to snap into the end face of two draw-bar seats with clamp, then measures, with micrometer, the size that clamp measure, i.e.
The size of A1+A2, then using this size divided by 2 as the size of A1 or A2.But this result is in fact
The mean value of A1 and A2 measurement size.Its actual conditions are likely to A1 ≠ A2, A1 ＜ A2 or A1 ＞ A2 etc.
Multiple different situations.That is, although the entity size numerical value of surveyed A1+A2 is qualified, but A1 or
A2 size value is not necessarily qualified.For example, A1 ≠ A2 just illustrates in center and the axle box endoporus of A1+A2 size
The heart is misaligned, center deviation i.e. dimension overproof phenomenon occurs.Although therefore this metering system operating efficiency is high,
But certainty of measurement cannot be ensured.
Another kind of method of the prior art is to utilize three coordinate measuring machine to measure.This method is by workpiece
Hang onto on three coordinate measuring machine, find out endoporus center by axle box inner diameter edge, then to A1, A2 size
Detect respectively.Although this measuring method can meet the requirement of certainty of measurement, but measurement process is loaded down with trivial details,
Time is long, and efficiency is low, it is impossible to meet the needs of axle box production cycle.
Content of the invention
The purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of accurate, convenient, efficient
Device and method is surveyed in locomotive axle box health check-up.
The object of the present invention is achieved like this: device is surveyed in a kind of locomotive axle box health check-up, including measurer and gauge block,
It is characterized in that:
The structure of described measurer is, the top board of swollen tire welds two arch extending laterally and upwards arching upward and surveys chi
Cantilever, two terminations surveying chi cantilevers respectively install difference in size and survey chi, and skeleton and swollen tire top board are in same flat
Face, its two ends are respectively welded surveys chi cantilever termination in two, is fixed on swollen tire top by welding gusset above middle part
On plate, equipped with bolt below middle part；
The structure of described gauge block is, a standard ring identical with hole nominal dimension in locomotive axle box body, and tool is to two
The ear block identical with draw-bar seat interplanar distance nominal dimension is stretched out in side.
The measuring method of device is surveyed in a kind of above-mentioned locomotive axle box health check-up, it is characterised in that take the following step:
A. the calibration of measurer
A. swollen for measurer tire is put in gauge block standard ring；
B. swollen tire and bolt are adjusted so that it is fit tightly with standard ring endoporus and difference in size surveys chi and ear block
Tested surface is vertical；
C. difference in size is made to survey the tested surface against ear block for the chi termination；
D., the display that difference in size is surveyed chi is adjusted to zero-bit；
B. the measurement of workpiece
E. the swollen tire of measurer after calibrating is put in the endoporus of measured workpiece；
F. expander and bolt are adjusted so that it is fit tightly with the endoporus of workpiece and difference in size is surveyed chi and drawn with tested
Pole socket face is vertical；
G. difference in size is made to survey chi termination against tested pull bar seat surface；
H. the dimension difference recording is recorded；
I. the dimension difference of actual measurement is compared with the dimensional tolerance value of design code, it is determined that whether qualified workpiece is.
Technical scheme, utilizes swollen tire structure in measurer dexterously, solves quick determination well
A difficult problem for axle box endoporus center measurement point, with low cost, easy and simple to handle, improve operating efficiency, meet
The needs of axle box production cycle.

Detailed description of the invention
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, real below in conjunction with the present invention
Execute the accompanying drawing in example, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that institute
The embodiment describing is a part of embodiment of the present invention, rather than whole embodiments.Based on the reality in the present invention
Execute example, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Referring to accompanying drawing, device is surveyed in the locomotive axle box health check-up of the present embodiment, including measurer and gauge block two parts.Measurer
Part uses swollen tire 5 to position, and welds two and survey chi cantilevers 2 on swollen tire top board 13, in extending laterally and upwards
The arch of arch.Two terminations surveying chi cantilever 2 are respectively installed a difference in size with digital display screen 7 and are surveyed chi 3.Skeleton
11 are in same plane with swollen tire top board 13, and its two ends are respectively welded in two terminations surveying chi cantilever 2, middle part
Top is fixed on swollen tire top board 13 by welding gusset 12, equipped with bolt 8 below middle part.Gauge block is one
The individual standard ring 9 identical with hole nominal dimension in locomotive axle box body, tool stretches out public with draw-bar seat interplanar distance to both sides
Claim equivalently-sized ear block 10.
During measurement, first carry out the calibration of measurer.First swollen for measurer tire 5 is put in gauge block standard ring 9, adjust swollen
Tire 5 and bolt 8 so that it is fit tightly with the endoporus of standard ring 9, and difference in size survey chi 3 and ear block 10
Tested surface vertical, then make difference in size survey the tested surface against ear block 10 for the termination of chi 3, now difference in size surveyed
The display of chi is adjusted to the calibration that zero-bit i.e. completes measurer.
Then carrying out the actual measurement of workpiece, step is substantially the same with the calibration of measurer.Measurer after calibrating is swollen
Tire 5 is put in the endoporus of measured workpiece 6, adjusts expander 5 and bolt 8 so that it is tight with the endoporus of workpiece 6
Laminating, and difference in size to survey chi vertical with tested pull bar seat surface 4, then make the termination of difference in size survey chi 3 against tested
Pull bar seat surface 4, now records the difference in size reading of display screen 7.Chi by the dimension difference of actual measurement and design code
Very little tolerance value compares, and i.e. can determine that whether qualified the workpiece of processing is.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；
Although being described in detail the present invention with reference to previous embodiment, those of ordinary skill in the art should manage
Solve: it still can the technical scheme described in foregoing embodiments be modified, or to wherein part skill
Art feature carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this
Invent the spirit and scope of each embodiment technical scheme.
