Description
Technical field
The utility model relates to automobile parts tooling fields more particularly to a kind of experiment of dust cover to use tooling.
Background technique
Dust cover is a component important in automobile pneumatic system, avoids dust from entering by dust cover, while dust-proof
Cover must have preferable leakproofness, and there can be no gas leak phenomenons, to influence air pressure.Therefore the measurement for dust cover airtightness
It is particularly significant, need to carry out experiment of leaking hunting to dust cover before storage, at present frequently with experiment method it is very troublesome, without special
The test fixture of door, the efficiency that causes to leak hunting is lower, has seriously affected production efficiency.
Summary of the invention
The utility model is in view of the above-mentioned problems, provide a kind of dust cover experiment tooling, dedicated for leaking hunting for dust cover
Experiment, greatly improved conventional efficient.
The utility model is achieved by the following technical solution, and provides a kind of dust cover experiment tooling, including water tank
With wear the leak pipe being fixed in water tank bottom, the leakage water pipe and water tank bottom is connected by thread seal, leak pipe
Upper end extends in water tank and is arranged the flange for being connected with and being bolted with dust cover, and the upper surface of the flange is equipped with and leakage
Water pipe coaxial and the groove for being greater than leak pipe latus rectum.
When in use, dust cover is fixed on flange for this programme, keeps dust cover mouth opposite with leak pipe, then to dust-proof
It is filled to liquid level on cover higher than dust cover top, and keeps certain time, if there are flowing out in leak pipe, illustrates dust cover
Airtightness is undesirable, and leakage water pipe and water tank bottom is connected through a screw thread, and not only improves the sealing between leakage water pipe and water tank,
It can be adjusted again according to the height that the height of dust cover protrudes into water tank leak pipe, improve versatility；It is set on flange
Groove is set, it is even closer to guarantee that dust cover is bonded with flange, to guarantee the sealing between dust cover and flange, avoids water by preventing
Leak pipe is flowed between dust hood and flange.
As optimization, gasket is additionally provided between dust cover and flange.This prioritization scheme by dust cover and flange it
Between gasket is set, further ensure the sealing between dust cover and flange.
It further include stand for experiment as optimization, the water tank is fixed in stand for experiment, is additionally provided with and is located in stand for experiment
Water content detection test paper below leak pipe.This prioritization scheme facilitates water tank and water content detection test paper to put by setting stand for experiment
It sets, by setting water content detection test paper to whether leak detects, when on leak Guan Zhongyou water droplet to water content detection test paper, examination
Paper color changes, and can more intuitively judge whether leak for operator, without staring at leak pipe always, and
And multiple dust cover leak tests can be carried out simultaneously, improve conventional efficient.
As optimization, the leak pipe is transparent material, and the lower end of leak pipe connects feeder, the pipe by pipeline
Valve is installed on road.The setting of this prioritization scheme, which allows, leaks hunting experiment by gas supply completion, and the liquid level in water tank is high
When at the top of dust cover, by the valve in opening conduits, feeder is passed through gas into dust cover, if occurred in water tank
Bubble then illustrates that the airtightness of dust cover is insufficient；By setting transparent for leak pipe, observed in leak pipe in the injecting process
Whether have under water flow, if there is under water flow, then illustrating that dust cover airtightness is bad, if under non-water flow, then in opening conduits
Valve is ventilated；The valve on pipeline is closed after leaking hunting, and the water in water tank is poured into temporary container, replaces dust cover
The water in temporary container is poured into water tank again afterwards, in order to avoid cause the waste of water；Feeder can be air compressor machine, be also possible to store up
Gas tank.
As optimization, the Draw off valve lower than flange is installed on the water tank.By the way that Draw off valve is arranged, facilitate water
Water in case is discarded to liquid level lower than flange, flows into steam line to avoid the water in water tank when replacement dust cover.
As optimization, the lower end of the leak pipe is connect by loose joint with pipeline.The setting of this prioritization scheme make pipeline with
The connection of leak pipe is more convenient, avoids pipeline by stubborn bending.
The utility model has the following beneficial effects: dust cover is fixed by the way that setting flange is convenient, by leak pipe
Whether the airtightness that judges dust cover there are flowing out, it is easy to operate, efficiency of leaking hunting is improved, and structure is simple, cost of manufacture
It is low；It is collected to leaking hunting with water by water tank, avoids water resource waste.

Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
Embodiment one
A kind of dust cover experiment tooling as shown in Figure 1, including water tank 1 and wears the leak pipe being fixed in water tank bottom
2, the leak pipe 2 is connect with water tank bottom by thread seal, and the upper end of leak pipe extends in water tank and is arranged and is connected with
Flange 3, flange 3 are bolted with dust cover 8, and the upper surface of the flange 3 is equipped with leakage water pipe coaxial and greater than leak
The groove of pipe latus rectum is additionally provided with gasket between dust cover 8 and flange 3 to improve sealing effect.
The present embodiment further includes stand for experiment 10, and the water tank 1 is fixed in stand for experiment 10, and stand for experiment 10 is equipped with
Place the support slot of water tank, the water content detection test paper 9 being additionally provided with below leak pipe in stand for experiment.
When the present embodiment is in use, dust cover is fixed on flange, keeps dust cover mouth opposite with leak pipe, then to anti-
It is filled to liquid level on dust hood higher than dust cover top, and keeps certain time, if there are flowing out in leak pipe, illustrates dust-proof
Cover airtightness is undesirable, depending on the retention time after water filling requires according to specific experiments.
Embodiment two
The difference between this embodiment and the first embodiment lies in being equipped with the Draw off valve 4 lower than flange on water tank 1；Leak pipe
For transparent material, feeder 7 is connected by pipeline 6 in the lower end of leak pipe, valve is installed on the pipeline.Connect for convenience
It connects, the lower end of leak pipe 2 is connect by loose joint 5 with pipeline 6.Gas supply feeder in the present embodiment is air accumulator, opens pipe
When valve on road, the high pressure gas in air accumulator is flowed into dust cover.
The present embodiment injects water into water tank in use, first by dust cover and flanged joint, and leakage is observed in the injecting process
Whether have under water flow in water pipe, if there is under water flow, then illustrating that dust cover airtightness is bad, if under non-water flow, in water tank
Liquid level be higher than dust cover at the top of after, the valve in opening conduits, feeder is passed through gas into dust cover, if in water tank
There is bubble, then illustrates that the airtightness of dust cover is insufficient, embodiment improves the accuracys detected to dust cover gas leakage；It leaks hunting
After close the valve on pipeline, and the water in water tank is poured into temporary container, will be kept in again after replacing next dust cover
Water in container pours into water tank, in order to avoid cause the waste of water.
