Description
Technical field
This utility model relates to the frock that automobile manufacturing field is used, and is specifically related to what a kind of engine rig test was used
Centralising device.
Background technology
Electromotor is the heart of automobile, and the assembling quality of electromotor is directly connected to the quality of car load, therefore at electromotor
After having assembled, will test, to check the quality condition of electromotor.The delivery test of electromotor, it is simply that according to electromotor
Operating principle, makes electromotor get into smooth by special stand.The delivery test of electromotor typically has cold examination and heat examination two kinds,
The feature of cold examination maximum need not igniting exactly, and engine ignition is got into smooth by heat examination exactly, the same with operating onboard.Though
Right cold examination advantage of lower cost, but because of it, heat examination can check that project is more, and become main flow detection means.The examination of dispatching from the factory of electromotor
Testing is that the various performances to electromotor do comprehensively inspection, and to mass production, electromotor delivery test is usually at Special-purpose bench
On, test by certain test specification.By test.Can check whether the parts quality of electromotor, assembling have mistakes and omissions
Dress, if leak, gas or oil, and speed governing and power situation.Also can check starting system, fuel oil supply system, cooling simultaneously
The working condition of water supply system, engine control system, engine combustion exhaust emission system, pressure charging system etc..
The mounting axis centering guaranteeing electromotor and dynamometer machine during test is to test critical process accurately.If electromotor
Center and dynamometer machine center the most point-blank, power measurement can be caused inaccurate, can cause time serious electromotor or
Person's dynamometer machine damages, and more likely causes connecting shaft to rupture, and endangers personal safety.
Current centering has column to neutralizing trolley type to medium method.Column centering method accuracy of alignment is high, logical
Strong by property, fixed.The centering time is long, it is impossible to meet the requirement of delivery test quick centring, trolley type centering time
Short, poor universality, safety is the highest.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of engine rig test for above-mentioned prior art
With centralising device, simple in construction, highly versatile, it is possible to realize the quick centring between engine crankshaft and test-bed main shaft.
The technical scheme in the invention for solving the above technical problem is: a kind of engine rig test centering fills
Putting, including the base for supporting electromotor, the top of described base is provided with fixing locating piece and movable briquetting, described
Briquetting is combined with compression cylinder, and described compression cylinder drives aforementioned briquetting to be fixed on base by electromotor；Set on described base
It is equipped with alignment pin, hole, the location corresponding matching of design with described alignment pin and engine.
It is preferred that described base is supported on the base plate of level levelling, the dynamometer machine for test engine also supports
On which floor plate, try one's best on a height in the center of the center line and dynamometer machine that thus conveniently adjust electromotor.
Further, centralising device also includes compressing control chamber, and described compression control chamber is used with compression cylinder electrical connection
In compression and the release of control briquetting, simplify operation, improve centering efficiency.
The operation of above-mentioned centralising device quick centring is that dynamometer machine and centralising device are placed on the end that levels of planarity is the highest
On plate, determine that according to test request the center of dynamometer machine is high, determined the height of centralising device by the centrage of engine crankshaft,
Try one's best at a height in the center line making electromotor with this and the center of dynamometer machine.Then the position of electromotor is adjusted with dial gauge,
The axiality making electromotor and dynamometer machine reaches ± 0.2mm within.Electromotor is made quick and precisely to fall base by alignment pin
On, then press the operation button compressed on control chamber, by briquetting, engine reliable is fixed, finally by the flower on dynamometer machine
Being keyed on the flywheel of electromotor, with the urgent fixing bolt of air pressure gun, i.e. complete whole centering operation, whole process has only to 1 point
Clock, centering precise and high efficiency.
Compared with prior art, the utility model has the advantage of: provide the centralising device of a kind of simple in construction, it is achieved
Fast and reliable centering between electromotor and dynamometer machine, accuracy of alignment and efficiency all improves a lot.
Accompanying drawing explanation
Fig. 1 is the Shaft alignment state schematic diagram of electromotor and dynamometer machine in this utility model embodiment；
Fig. 2 is the schematic diagram of centralising device.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As depicted in figs. 1 and 2, the centralising device 2 of the engine rig test in the present embodiment, starts including for support
The base 201 of machine 3, base 201 is supported on the base plate 1 of level levelling, and the dynamometer machine 4 for test engine 3 is also supported on
On this base plate 1, thus try one's best on a height in the center of the convenient center line adjusting electromotor 3 and dynamometer machine 4.Base 201
Top is provided with fixing locating piece 202 and movable briquetting 204, and briquetting 204 is combined with compression cylinder 203, compression cylinder 203
Controlled by compressing control chamber (not shown), before pressing the button compressed on control chamber compression cylinder 203 can be made to drive
State briquetting 204 to be fixed on base 201 by electromotor 3.Be provided with alignment pin 205 on base 201, described alignment pin 205 with send out
Hole, the location corresponding matching of design on motivation fuselage.
The operation of above-mentioned centralising device quick centring is that dynamometer machine and centralising device are placed on the end that levels of planarity is the highest
On plate, determine that according to test request the center of dynamometer machine is high, determined the height of centralising device by the centrage of engine crankshaft,
Try one's best at a height in the center line making electromotor with this and the center of dynamometer machine.Then the position of electromotor is adjusted with dial gauge,
