Description

Airtight test device
Technical field
The present invention relates to assist field, be specifically related to airtight test device.
Background technology
All need to carry out air-leakage test to the seal member of Related product in many industries such as automobile, combustion gas, household electrical appliances, aviation, military project, for some product, gas seal property is vital performance index.The bad meeting of impermeability causes leakage, by directly affecting the reliability of product, economy and overall performance, causes occurring the problems such as the reduction of malfunctioning machine, operation exception, efficiency, the lost of life in actual use.Most employing bowssening, hydrostatic(al) process, liquid soap method, supercritical ultrasonics technology, helium leak check device method, traditional gas detection methods etc. detect to product hermeticity in current domestic enterprise, there is the test duration separately long, inefficiency in these methods.
Summary of the invention
In order to solve the problem, the invention provides a kind of test duration short, test speed is fast, and work efficiency is high, and test safety, test result is airtight test device accurately.
Airtight test device of the present invention, comprise water vat and gas-holder, it is characterized in that, described water vat upper surface is provided with a pressing plate, the lower surface of described pressing plate is provided with clamp device, described clamp device and the cylinders being arranged on pressing plate upper surface, described pressing plate is also provided with a pick-up unit and air intake opening, described gas-holder is connected with air intake opening by air inlet pipeline, air inlet pipeline is provided with one or two two-way valve, and water vat one sidewall bottom is provided with water inlet.
Preferably, clamp device and work piece interface are provided with sealing gasket.
Preferably, clamp device is an arch bar and L shape bar composition, one corner of described arch bar is connected with press plate rotary, one end that distance arch bar corner is nearest and cylinders, L shape bar is fixed on pressing plate, and its horizontal component is towards arch bar side, L shape bar be hollow and be connected with air intake opening.
Preferably, pick-up unit comprises an air chamber, and described air chamber lower end is provided with a level sensor, and air chamber upper end is connected with safety valve by pressure transducer.
Test duration of the present invention is short, and test speed is fast, and work efficiency is high, and test safety, test result is accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of airtight test device.
Fig. 2 is the partial enlarged drawing of A-A in Fig. 1.
Reference numeral: 1-water vat, 2-pressing plate, 3-arch bar, 4-L shape bar, 5-sealing gasket, 6-air intake opening, 7-2/2-way valve, 8-gas-holder, 9-cylinder, 10-air chamber, 11-level sensor, 12-pressure transducer, 13-safety valve, 14-water inlet, 15-detected element.
Embodiment
Airtight test device of the present invention, comprise water vat 1 and gas-holder 8, described water vat 1 upper surface is provided with a pressing plate 2, the lower surface of described pressing plate 2 is provided with clamp device, described clamp device is connected with the cylinder 9 being arranged on pressing plate 2 upper surface, described pressing plate 2 is also provided with a pick-up unit and air intake opening 6, and described gas-holder 8 is connected with air intake opening 6 by air inlet pipeline, air inlet pipeline is provided with one or two two-way valve 7, described water vat 1 one sidewall bottom is provided with water inlet 14.Clamp device and work piece interface are provided with sealing gasket 5.Described clamp device is that an arch bar 3 and a L shape bar 4 form, one corner and the pressing plate 2 of described arch bar 3 are rotatedly connected, one end nearest apart from arch bar 3 corner is connected with cylinder 9, L shape bar 4 is fixed on pressing plate 2, and its horizontal component is towards arch bar 3 side, that L shape bar 4 is hollow and be connected with air intake opening 6.Described pick-up unit comprises an air chamber 10, and described air chamber 10 lower end is provided with a level sensor 11, and air chamber 10 upper end is connected with safety valve 13 by pressure transducer 12.
During use, by detected element 15 clamping between arch bar 3 and L shape bar 4, piston driving arch bar 4 is promoted by cylinder 9, thus realize the clamping of detected element 15, detected element 15 after clamping is positioned in water vat 1, now guarantee that pressing plate 2 and water vat 1 seal, water is injected by water inlet 14, water level is elevated to air chamber 10 mouthfuls, level sensor 11 sends signal, then stop water filling, now in detected element 15, pass into pressurized air by gas-holder 8, the pressure in air chamber 10 is measured by pressure transducer 12, the pressure in air chamber 10 is measured according to pressure transducer 12, judge whether occur bubble in water, thus judge that whether the impermeability of detected element 15 is qualified, according to PLC control system, then robotization can be realized.Because detected element 15 may be leaked seriously, after passing into pressurized air, may produce a large amount of bubble, for this kind of situation, this device adds safety valve 13 and 2/2-way valve 7, if hypertonia in air chamber, close 2/2-way valve 7, open the safety-valve 13 venting.
