Abstract
The utility model relates to an air leakage testing machine of a fuel rail, which comprises a fuel rail and a testing machine, wherein the fuel guide rail comprises a fuel inlet port and a fuel returning port, and the testing machine comprises a base, a rail positioning mechanism arranged on the base, and a fuel inlet port sealing mechanism and a fuel returning sealing mechanism which are arranged on the base. In addition, in order to record the testing result on the fuel guide rail, the machine is provided with a marking mechanism. The assembling machine has comparatively simple structure, and so the operation is very easy.
Description
Technical field
The utility model relates to a kind of test fixture, relates in particular to a kind of air leak-testing frock of fuel rail.
Background technology
In the assembling process of fuel rail, need the leakage index of detection guide rail whether qualified.The normally air leak detection of the mode of leak detection.For this reason, need provide corresponding air leak detection tool equipment.Operating personnel always expect frock simple in structure, easy and simple to handle.Yet the structure of existing fuel rail air leakage frock is more complicated all, and these complicated frocks are not easy to assembly crewman's use.Therefore, be necessary to provide a kind of air leak-testing frock of fuel rail simple in structure, easy and simple to handle.
The utility model content
The purpose of this utility model is the air leak-testing frock that a kind of fuel rail will be provided, and this test fixture is simple in structure, easy and simple to handle.
To achieve these goals, the air leak-testing frock of the utility model fuel rail adopts following technical scheme:
A kind of air leak-testing frock of fuel rail, wherein fuel rail comprises oil-in and oil return opening, this test fixture comprises: base; Be located at the guide rail detent mechanism on the base; And be located at oil-in sealing mechanism and oil return opening sealing mechanism on the base.Such test fixture is simple in structure, and therefore operation is very easy.
A preferred embodiment as the air leak-testing frock of the utility model fuel rail, oil-in sealing mechanism and oil return opening sealing mechanism include seal head and clamp, clamp connect an end of seal head to move and location sealing head, the other end of seal head connects oil-in or oil-out, and seal head inside is provided with air duct that communicates with oil-in or oil-out and the air scoop that communicates with this air duct.
Another preferred embodiment as the air leak-testing frock of the utility model fuel rail also is provided with two handles on the base.It is the mobile of test fixture for convenience that handle is set.
As another preferred embodiment of the air leak-testing frock of the utility model fuel rail, also comprise the marking mechanism of the use ink that can on fuel rail, make marks.So just the mark relevant with test result down can in time done on fuel rail after the end of test (EOT).
Description of drawings
Fig. 1 is the schematic plan of a preferred embodiment of the air leak-testing frock of the utility model fuel rail.
Embodiment
Be described in detail below in conjunction with the air leak-testing frock of accompanying drawing the utility model fuel rail.
Fig. 1 is the schematic plan of a preferred embodiment of the air leak-testing frock of the utility model fuel rail.As shown in Figure 1, this test fixture comprises base 1, is located at the guide rail detent mechanism 4 on the base 1 and is located at oil-in sealing mechanism 3 and oil-out sealing mechanism 2 on the base 1.Wherein, fuel rail 6 comprises oil-in 61 and oil-out 62.In addition, guide rail detent mechanism 4 is existing locating device, therefore no longer this is described in detail below.
As shown in Figure 1, as a preferred embodiment of the air leak-testing frock of the utility model fuel rail, oil-in sealing mechanism 3 comprises seal head 32 and clamp 31.Clamp 31 connect an end of seal head 32, thereby hydrodynamic reciprocating sealing head 32 also can be fixed on seal head 32 on the required ad-hoc location to and fro.The other end of seal head 32 connects oil-in 61 to seal this oil-in.In order to guarantee that seal head 32 moves to dock with oil-in 61 along set direction, also is provided with the guide piece of seal head 32 on the base 1.The inside of seal head 32 is provided with air duct (not shown) that communicates with oil-in 61 and the air scoop 33 that communicates with this air duct.Similar with oil-in sealing mechanism 3, oil-out sealing mechanism 2 comprises seal head 22 and clamp 21.Clamp 21 connect an end of seal head 22, thereby hydrodynamic reciprocating sealing head 22 also can be fixed on seal head 22 on the required ad-hoc location to and fro.The other end of seal head 22 connects oil-out 62 to seal this oil-out.In order to guarantee that seal head 22 moves to dock with oil-out 62 along set direction, is provided with the guide piece of seal head 22 too on the base 1.The inside of seal head 22 is provided with air duct (not shown) that communicates with oil-out 62 and the air scoop 23 that communicates with this air duct.
Still as shown in Figure 1,, each side establish a handle 11,12 on the base 1, to make things convenient for moving of this test fixture as another preferred embodiment of the air leak-testing frock of the utility model fuel rail.A same embodiment of the others of this embodiment repeats no more herein.
Still as shown in Figure 1, another preferred embodiment as the air leak-testing frock of the utility model fuel rail, this test fixture also comprises the marking mechanism that uses ink, so that in time on guide rail, staying after the end of test (EOT) and the corresponding mark of test result, be hard to tell the guide rail of different test results after preventing.The others of present embodiment are identical with one of the foregoing description.
The test process of the air leak-testing frock of the utility model fuel rail is as follows:
At first fuel rail 6 is positioned on the detent mechanism 4, mobile respectively then clamp 21 and 31 are so that seal head 22 docks with oil-out 62, seal head 32 docks with oil-in 61, and like this, oil-in 61 and oil-out 62 have just been sealed respectively.After oil-in 61 and oil-out 62 are sealed, just the air leak detector is connected respectively on air scoop 23 and 33, in fuel rail 6, to fill pressure-air.When the air pressure in the fuel rail 6 reached predetermined value, inflation will stop.Subsequently, whether the pressure of air falls the air leak detector in the guide rail with regard to beginning to test in the time of determining, qualified with the aeroseal of determining this guide rail.Come out etc. test result, just write corresponding mark with marking mechanism at this guide rail, for example " qualified " or " defective ".Arrive this, the air test process of this guide rail just is through with.
Above example is the unrestricted technical scheme described in the utility model in order to explanation the utility model only.Therefore,, will be understood by those skilled in the art that, still can make amendment or be equal to replacement the utility model although this instructions has been described in detail the utility model with reference to above-mentioned example; And all do not break away from the spirit of utility model and technical scheme and the improvement of model figure, and it all should be encompassed in the claim scope of the present utility model.
