Description
Technical field
The present invention relates to diesel locomotive diesel generating set technical field.
Background technology
In the assembling process of diesel locomotive, bavin hair units' installation seat surface is generally six, wherein four are used for diesel engine,
Two be main generator supporting, the flatnesses of six mounting seats typically requires to be 6mm, and planarity requirements are during locomotive overhaul
7mm. only has that flatness is qualified, could reduce vibration after bavin hair units' installation, operate steadily, it is ensured that locomotive total quality.
It is to be measured using ordinary optical height-gauge in the prior art, but optical height measuring instrument equipment is expensive, weight
Amount, volume are big, can not manually carry, and at least 3 people could complete one-shot measurement work.Complex operation is, it is necessary to which record data is carried out
Contrast conting, it is impossible to go out result at once, cause to delay work sometimes, measurement cost is high.
The content of the invention
Technical problem solved by the invention is to provide a kind of diesel locomotive easy to operate, cost is low, measurement efficiency is high
Diesel generating set mounting seat flatness inspection devices and method.
The technical solution adopted by the present invention is diesel locomotive diesel generating set mounting seat flatness inspection devices, including
Two height gauges, height gauge include rod support and scale arm, and scale arm short transverse is marked with scale, the scale on two height gauges
Unanimously, scale arm short transverse and rod support bottom surface keep vertical, in addition to a transparent U-tube, and filling liquid, U-shaped in U-tube
The two-arm and height arm of pipe fit.Filling colored liquid in U-tube.It is made up in the middle part of U-tube of flexible material.
The method of diesel locomotive diesel generating set mounting seat flatness inspection devices,
(1) liquid is poured into U-tube；
(2) two height gauges are individually positioned in tested diesel locomotive diesel generating set mounting seat center；
(3) two-arm for the U-tube for filling liquid is close to the scale of two height gauges along short transverse respectively；
(4) scale that height gauge coincides with liquid level in U-tube in two mounting seats, respectively H1, H2 are recorded；
(5) on the basis of the liquid level under this state, measured successively with height gauge height H3 corresponding to remaining mounting seat,
H4 is until Hn；
(6) the difference h of maxima and minima in H1-Hn is calculated, if h, in error range, mounting seat is qualified；If h is big
In error range, then mounting seat is unqualified.
The invention has the advantages that a kind of simply and effectively measuring method is invented using U-tube and height gauge, it is not tested
The limitation of the conditions such as place is measured, completes the hair units' installation seat measurement of planeness work of diesel locomotive bavin.
Brief description of the drawings
Fig. 1 is measuring principle figure of the present invention.
Fig. 2 is height gauge structure chart.
In figure mark for：1- height gauges, 11- scale arms, 12- rod supports, 2-U type pipes, the pink liquid of 3-, 4- mounting seats two,
5- mounting seats one.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
A horizontal plane is established as measurement altitude datum by the use of U-tube device during measurement, and six are measured respectively with height gauge
For individual mounting seat to the height distance of horizontal plane, difference in height is the flatness of six mounting seats.Realize that bavin hair units' installation seat is put down
The purpose of face degree measurement.
For the important step of the present invention, it is necessary to by Fig. 1 manufacture height gauges 1 of two pieces 300, blade will have preferable rigidity,
Height gauge includes rod support 12 and scale arm 11, and the short transverse of scale arm 11 is marked with scale, precision 0.5mm, two height gauges 1
On scale distribution it is completely the same, the short transverse of scale arm 11 and the bottom surface of rod support 12 keep vertical, and the error of perpendicularity is not more than
0.4mm。
U-tube 2 is the plastic, transparent pipes of ￠ 10,2.5 meters of length, and flexibility is good.Liquid uses the water of pink colour in pipe,
Poured into during measurement in pipe, Bu Yaoman, both ends reserve the position of hand handle.
Mode of operation：Two people operate simultaneously, 300 height gauges 1 are placed to tested mounting seat center respectively, then will be equipped with
The U-tube 2 of pink colour liquid is close to the scale of height gauge 1 along short transverse, and after putting surely, liquid level is as new in both sides U-tube 2
The horizontal plane built, two height gauge scales corresponding to liquid level, it is height H1, H2 of the mounting seat to newly-built horizontal plane.With
On the basis of any one mounting seat, and height gauge used is motionless, and another mobile height gauge measures other mounting seats, and institute is right
Height H3, H4 is answered until H6；After measuring one by one, the maximum height difference of 6 mounting surfaces is flatness.
Necessarily it is in same plane this principle after both sides liquid level is stable in U-tube, and in this, as measuring basis,
When measuring different mounting seats, as long as keeping the liquid in U-tube not spill over, the height and position of this reference plane will not also become
Change.
Inventive combustion engine Che Chaifa units' installation seat method measuring flatness, may replace used optical height measuring instrument
Measurement, greatly shortens time of measuring, uses manpower and material resources sparingly, convenient and swift, accurate and effective, improves production efficiency, and saving is manufactured into
This.
