Abstract
The utility model discloses a vacuum testing device including a base, a test fixture, a vacuum generating assembly, a power switch and a valve terminal, wherein the vacuum generating assembly, the power switch and the valve terminal are fixed on the base. The vacuum generating assembly includes a vacuum pump and a flow control valve. The vacuum pump communicates with the valve terminal through a gas-guide tube. A cavity is disposed in the test fixture. The valve terminal communicates with the cavity of the test fixture through a ventilating tube. A through hole communicating with the cavity is disposed in the side wall of the test fixture. A test table is inserted in the through hole. The shape of the test fixture needs to be adaptive to that of a specific product, and the test fixture functions as a part adaptive to the product and capable of simulating a test with the product assembled; and when the vacuum testing of product sealing performance can be met, equipment is installed in a miniaturized and integrated manner on a mobile base to facilitate movement, and the vacuum testing device can be flexibly applied to production lines.
Description
Technical field
The utility model relates to the bubble-tight device of a kind of test, relates in particular to a kind of sealing property vacuum test device.
Background technology
Automobile-used pump is common body parts, and it requires higher to impermeability, thereby the impermeability of product detects the important step that becomes the product quality of checking on.At present, the method for conventional vacuum test is done air tightness test, and common vacuum test device is that it mostly is fixed apparatus, its process structure complexity, integral device is larger, thus mobile inconvenience, cannot flexible Application in producing line.So a kind of simple and reasonable, be convenient to mobile, can apply in a flexible way urgently occurs in the vacuum checking device that produces line.
Utility model content
In order to address the above problem, the utility model provides a kind of simple and reasonable, mobile vacuum test device flexibly.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of sealing property vacuum test device, comprises base, test fixture and is fixed on vacuum generating assembly, the power switch He Fa island on base; Described vacuum generating assembly comprises vacuum pump and flow control valve, described vacuum pump is connected with described valve island through a wireway, one inner chamber is set on described test fixture, described valve island is by the intracavity inter-connection of a ventilating pipe fitting and described test fixture, on the sidewall of described test fixture, be also provided with a through hole being communicated with described inner chamber, on this through hole, 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 the first ball valve is connected with described valve island, the intracavity inter-connection of described the 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, on described base, be installed with a pair of handle.
Preferably, on described test fixture, be provided with leader.
Pass through technique scheme, the sealing property vacuum test device that the utility model provides, 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 in the situation that assembling, and in can meeting vacuum test products air tightness function, by device miniaturization, integrated being arranged on a movable base, be convenient to mobile, can flexible Application in producing line.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the structural representation of the disclosed a kind of sealing property vacuum test device of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
A kind of sealing property vacuum test device, referring to Fig. 1, comprises base 11, test fixture 10 and is fixed on vacuum generating assembly, the power switch 12He Fa island 13 on base 11, is installed with a pair of handle 14 that is convenient to the whole device of moved by hand on base 11.Vacuum generating assembly comprises vacuum pump 15, for regulating the flow control valve 16 that vacuumizes airshed, with for showing the flow indicator 17 that vacuumizes airshed, flow control valve 16 and flow indicator 17 are all fixed on valve island 13, and vacuum pump 15 is connected through a wireway 19Yu Fa island 13.On test fixture 10, arrange one with the suitable inner chamber 18 of shape of product, valve island 13 is connected with the inner chamber 18 of test fixture 10 by a ventilating pipe fitting, on the sidewall of test fixture 10, be also provided with a through hole 20 being communicated with inner chamber 18, on this through hole 20, assigned a test chart 21.On test fixture 10, be also provided with a handle 22 that is convenient to manually to take test fixture 10.
Ventilating pipe fitting comprises that the first ball valve 23, tracheae 24 and the second ball valve 25, the first ball valve 23Yu Fa islands 13 that connect successively connect, and the second ball valve 25 is connected with the inner chamber 18 of test fixture 10.In the time that the second ball valve 25 disconnects, valve island 13 and test fixture 10 not conductings of gas circuit, in the time that the second ball valve 25 is opened, valve island 13 and test fixture 10 gas circuit conductings.
In use, by stuck the inner chamber 18 of product and test fixture 10; Then, start power switch 12, vacuum pump 15 produces vacuum, open respectively the first ball valve 23 and the second ball valve 25, because vacuum pump 15Yu Fa island 13, test fixture 10 gas circuits communicate, vacuum generating device is taken the air in test fixture 10 away, and now the inner chamber 18 of test fixture 10 produces vacuum.If products air tightness is good, air tight, the numerical value of test chart 21 pointed that are communicated with test fixture 10 can not change within a certain period of time; If products air tightness is bad, there is gas leak phenomenon, can there is beat in test chart 21 pointers.
To sum up, the vacuum test device that the utility model provides, 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 in the situation that assembling, and in can meeting vacuum test products air tightness function, by device miniaturization, integrated being arranged on a movable base, be convenient to mobile, can flexible Application in producing line.
To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
