Description
Technical field
The utility model is related to wheel rim testing equipment field, specifically refers to a kind of helium leak test gas equipment, and it detects wheel rim
Whether gas leakage when the characteristics of there is efficiency high and strong accuracy.
Background technology
Wheel rim by generally comprising wheel rim, spoke and mounting disc after casting, the wheel rim in a ring, in order to allow
The wheel rim formed out meets corresponding national standard, it is necessary to quality testing be carried out to the wheel rim of wheel rim, wherein critically important one
Secondary test is exactly to detect that wheel rim whether there is manufacturing deficiency, and the traditional way of this manufacturing deficiency is all to try method, the water using water
Examination method is by the way that the wheel rim after casting is placed in water, by sealing upper two opening, then toward internal insufflation gas, then
Determine whether that gas is emerged by way of eye-observation, this traditional mode of operation, at least in the presence of following defect：
One, is more less for some due to being that by the way of eye-observation, can only often find larger defect
Defect, the mode of human eye is difficult accurate judgement, and so quality to product causes certain uncontrollable factor, influences company pair
Outer quality performance.
Way conventional at present two, is due to being direct and atmosphere outside wheel rim, and being detected in water actually to imitate
The practical application of wheel rim, its actual Detection results are not still especially accurate, there is the space of improvement.
Based on this, the present inventor furthers investigate to this problem, there is this case generation then.
Utility model content
The purpose of this utility model is to provide a kind of helium leak test gas equipment, and it greatly improves wheel rim quality testing
Accuracy.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of helium leak test gas equipment, wherein, including wheel rim conveying mechanism, lower seal pad, upper sealing gasket, iron plate, outer cover
And gas leakage testing agency, through hole is formed with the middle part of the lower seal pad, and the iron plate is fixedly installed on the lower section of lower seal pad, should
Iron plate is also formed with second on correspondence insertion hole location formation helium pneumatic head and the first vacuum-pumping tube, the iron plate and vacuumized
Pipe；Wheel rim is delivered between lower seal pad and upper sealing gasket by the wheel rim conveying mechanism, second vacuum-pumping tube be located at wheel rim with
Between outer cover, wheel rim is divided into inner space and exterior space by sealing gasket and lower seal pad on this.
Further, the helium leak test gas equipment also includes wiper mechanism and drying mechanism, the wiper mechanism and drying mechanism
Positioned at the upstream position of wheel rim conveying mechanism.
Further, sealing gasket is formed with sealing surface in the side close to wheel rim on this, and the sealing surface is medium position height
The cambered surface that side is set low.
After such scheme, a kind of helium leak test gas equipment that the utility model is related to, it utilizes the first vacuum-pumping tube
Internal volume and exterior space are realized with the second vacuum-pumping tube while vacuumizing, then again toward injecting helium in inner space,
Such helium can be formed on the pressure side in wheel rim both sides, completely the pressure differential of simulation wheel rim real work, be realized to the most accurate of wheel rim
Really detection.
In addition, the utility model uses automatic detection, without manually measuring, accuracy is high, actual measurement effect
It is good.
Brief description of the drawings
Fig. 1 is that the utility model is related to a kind of structural representation of helium leak test gas equipment.
In figure：
Lower seal pad -1；Through hole -11；Upper sealing gasket -2；
Cambered surface -21；Iron plate -3；
Helium pneumatic head -31；First vacuum-pumping tube -32；Second vacuum-pumping tube -33；
Outer cover -4；Gas leakage testing agency -5；Wheel rim -6；
Inner space-S1；Exterior space-S2.
Embodiment
This case is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, the utility model is related to a kind of helium leak test gas equipment, including the conveying mechanism of wheel rim 6, lower seal pad
1st, upper sealing gasket 2, iron plate 3, outer cover 4 and gas leakage testing agency 5.
The middle part of lower seal pad 1 is formed with through hole 11, and the iron plate 3 is fixedly installed on the lower section of lower seal pad 1, the iron plate
3 are also formed with second at correspondence through hole 11 position on formation helium pneumatic head 31 and the first vacuum-pumping tube 32, the iron plate 3 takes out
Vacuum tube 33；Wheel rim 6 is delivered between lower seal pad 1 and upper sealing gasket 2 by the conveying mechanism of wheel rim 6, second vacuum-pumping tube
33 are located between wheel rim 6 and outer cover 4, on this sealing gasket 2 and lower seal pad 1 by wheel rim 6 points be internal space S 1 and exterior space
S2。
So, a kind of helium leak test gas equipment that the utility model is related to, it is taken out using the first vacuum-pumping tube 32 and second
Vacuum tube 33 realizes internal volume S1 and exterior space S2 while vacuumizing, then again toward injecting helium in internal space S 1,
Such helium can be formed on the pressure side in the both sides of wheel rim 6, completely the pressure differential of the simulation real work of wheel rim 6, be realized to wheel rim 6 most
Accurate detection.In addition, the utility model uses automatic detection, without manually measuring, accuracy is high, actual measurement effect
It is good.
The helium leak test gas equipment also includes wiper mechanism and drying mechanism, and the wiper mechanism and drying mechanism are located at wheel rim
The upstream position of 6 conveying mechanisms.
As shown in figure 1, sealing gasket 2 is formed with sealing surface in the side close to wheel rim 6 on this, the sealing surface is medium position
High and cambered surface 21 that side is set low.Using this cambered surface 21, sealing gasket 2 is allowed to apply the wheel rim 6 in different-diameter, and
Need not be regular more preferable, use is facilitated very much.
The foregoing is only preferred embodiment of the present utility model, it is all with the utility model right done it is equal
Deng change and modification, the scope of the utility model claim all should be belonged to.
