Abstract
The invention discloses a vacuum testing device. The vacuum testing device comprises a base, a testing clamp, a vacuum generation assembly fixed to the base, a power switch and a valve terminal. The vacuum generation assembly comprises a vacuum pump and a flow adjusting valve, and the vacuum pump is communicated with the valve terminal through an air guide pipe; an inner cavity is formed in the testing clamp, the valve terminal is communicated with the inner cavity of the testing clamp through a ventilating pipe, a through hole communicated with the inner cavity is formed in the side wall of the testing clamp, and a testing meter is inserted in the through hole. The shape of the testing clamp should be matched with that of a specific product, the clamping clamp is equivalent to a part matched with the product in the aspect of the function, and tests under the condition that the product is assembled well can be simulated; while the function of testing the air tightness of the product in a vacuum mode can be achieved, the testing device is minimized and integrally installed on the movable base, and therefore the testing device is convenient to move and capable of being widely applied to a production line.
Description
Technical field
The present invention relates to the bubble-tight device of a kind of test, particularly relate to a kind of sealing property vacuum test device.
Background technology
Automobile-used pump is common body parts, and it requires higher to impermeability, and thus the air-leakage test of product becomes the important step of product quality of checking on.At present, the method for conventional vacuum test does air tightness test, and common vacuum test device, and be that it mostly is fixed apparatus, its process structure is complicated, and integral device is comparatively large, so mobile inconvenience, cannot flexible Application in product line.So a kind of simple and reasonable, be convenient to mobile, can apply in a flexible way in the vacuum checking device producing line urgently occurs.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple and reasonable, mobile vacuum test device flexibly.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of sealing property vacuum test device, comprises base, test fixture and is fixed on vacuum generating assembly on base, power switch and valve island; Described vacuum generating assembly comprises vacuum pump and flow control valve, described vacuum pump is connected with described valve island through a wireway, described test fixture is arranged an inner chamber, the intracavity inter-connection of a ventilating pipe fitting and described test fixture is passed through on described valve island, the sidewall of described test fixture is also provided with one with the through hole of described inner space, this through hole has been assigned a test chart.
Preferably, described ventilating pipe fitting comprises the first ball valve, tracheae and the second ball valve that connect successively, and described first ball valve is connected with described valve island, the intracavity inter-connection of described second ball valve and described test fixture.
Preferably, described vacuum generating assembly also comprises flow indicator, and described flow control valve and flow indicator are all fixed on described valve island.
Preferably, described base is installed with a pair handle.
Preferably, described test fixture is provided with leader.
Pass through technique scheme, sealing property vacuum test device provided by the invention, the shape of test fixture need be suitable with the shape of specific product, its function is equivalent to the parts suitable with product, can the test of analog equipment when assembling, and while can meeting vacuum test products air tightness function, by device miniaturization, integratedly to be arranged on one piece of movable base, to be convenient to mobile, can flexible Application in product line.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the structural representation of a kind of sealing property vacuum test device disclosed in the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
A kind of sealing property vacuum test device, see Fig. 1, comprises base 11, test fixture 10 and fixing vacuum generating assembly on the pedestal 11, power switch 12 and valve island 13, base 11 is installed with the handle 14 being convenient to the whole device of moved by hand for a pair.Vacuum generating assembly comprises vacuum pump 15, for regulating the flow control valve 16 vacuumizing airshed, with for showing the flow indicator 17 vacuumizing airshed, flow control valve 16 and flow indicator 17 are all fixed on valve island 13, and vacuum pump 15 is connected with valve island 13 through a wireway 19.Test fixture 10 is arranged an inner chamber 18 suitable with shape of product, valve island 13 is connected with the inner chamber 18 of test fixture 10 by a ventilating pipe fitting, the sidewall of test fixture 10 is also provided with a through hole 20 be communicated with inner chamber 18, this through hole 20 has been assigned a test chart 21.Test fixture 10 is also provided with a handle 22 being convenient to manually to take test fixture 10.
Ventilating pipe fitting comprises the first ball valve 23, tracheae 24 and the second ball valve 25, first ball valve 23 that connect successively and is connected with valve island 13, and the second ball valve 25 is connected with the inner chamber 18 of test fixture 10.When the second ball valve 25 disconnects, valve island 13 and the not conducting of test fixture 10 gas circuit, when the second ball valve 25 is opened, valve island 13 and the conducting of test fixture 10 gas circuit.
In use, by stuck for the inner chamber 18 of product and test fixture 10; Then, start power switch 12, vacuum pump 15 produces vacuum, open the first ball valve 23 and the second ball valve 25 respectively, because vacuum pump 15 communicates with valve island 13, test fixture 10 gas circuit, the air in test fixture 10 is taken away by vacuum generating device, and now the inner chamber 18 of test fixture 10 produces vacuum.If products air tightness is good, air tight, then the numerical value of test chart 21 pointed be communicated with test fixture 10 can not change within a certain period of time; If products air tightness is bad, have gas leak phenomenon, then can there is beat in test chart 21 pointer.
To sum up, vacuum test device provided by the invention, the shape of test fixture need be suitable with the shape of specific product, its function is equivalent to the parts suitable with product, can the test of analog equipment when assembling, and while can meeting vacuum test products air tightness function, by device miniaturization, integratedly to be arranged on one piece of movable base, to be convenient to mobile, can flexible Application in product line.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
