Abstract
The utility model discloses swollen component in a kind of air bag, it includes cylinder, expansion core axis and air bag in air bag, expansion core axis connection in the piston rod and cylinder of cylinder, one end of expansion core axis and air bag connects in cylinder, compressed air pipe and detection gas source tracheae are provided in cylinder in expansion core axis, first gas outlet of compressed air pipe is located in air bag, and the second gas outlet of detection gas source tracheae is located at outside air bag.The utility model, by closure part not by additional force, can prevent workpiece from deforming compared with blocking end face, reduce workpiece and scratch；The utility model with it is interior it is swollen block compared with, this component outer diameter can 5mm smaller than aperture internal diameter or so, the positioning accuracy of workpiece can be reduced.
Description
Technical field
The utility model relates to swollen components in a kind of air bag.
Background technique
When carrying out airtight detection to part in the past, generally use two ways, one is seal face, this mode workpiece by
Power is easily-deformable, disfiguring workpiece；Another kind is to squeeze O-ring sealing, and for this mode to part requirements height, swell increment is too small.
Utility model content
In order to solve the above technical problems, the utility model provides swollen component in a kind of air bag.
To achieve the above object, the utility model adopts the following technical solutions:
Swollen component in a kind of air bag, it includes cylinder, expansion core axis and air bag in air bag, swollen in the piston rod and air bag of cylinder
Mandrel connects, one end of expansion core axis and air bag connection in air bag, is provided with compressed air pipe and detection in expansion core axis in air bag
First gas outlet of gas source tracheae, compressed air pipe is located in air bag, and the second gas outlet of detection gas source tracheae is located at air bag
Outside.
Further, the junction of expansion core axis and air bag one end is locked by the first locking nut in air bag.
Further, the other end of air bag is locked by the second locking nut.
Further, the second air inlet of the first air inlet of compressed air pipe and detection gas source tracheae passes through gasket
Sealing.
The utility model has the advantages that
1. the utility model compared with blocking end face, by closure part not by additional force, can prevent workpiece from deforming, reduce
Workpiece scratches.
2. the utility model with it is interior it is swollen block compared with, this component outer diameter can 5mm smaller than aperture internal diameter or so, can drop
The positioning accuracy of low workpiece.
3. the utility model can be used for various circle hole shape parts, widely used.
Detailed description of the invention
Fig. 1 is the perspective view of swollen component in the air bag of the utility model；
Fig. 2 is the sectional view of swollen component in the air bag of the utility model；
In figure: expansion core axis, 3- air bag, 4- compressed air pipe, the first gas outlet 41-, 41- in 1- cylinder, 2- air bag
One air inlet, 5- detection gas source tracheae, the second gas outlet 51-, the second air inlet of 52-, the first locking nut of 6-, 7- second lock
Tight nut, 8- gasket.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
The utility model proposes swollen components in a kind of air bag, and as shown in Figs. 1-2, it includes cylinder 1, expansion core axis 2 in air bag
With air bag 3 (expanded rubber), expansion core axis 2 is connected in the piston rod and air bag of cylinder 1, one end of expansion core axis 2 and air bag 3 in air bag
The locking of the first locking nut 6 was connected in connection, connection, and the other end of air bag 3 is locked by the second locking nut 7, swollen in air bag
Compressed air pipe 4 and detection gas source gas 5 are provided in mandrel 2, the first gas outlet 41 of compressed air pipe 4 is located at air bag 3
Interior, the second gas outlet 51 of detection gas source tracheae 5 is located at outside air bag 3, the first air inlet 42 of compressed air pipe 4 and detection
Second air inlet 52 of gas source tracheae 5 is sealed by gasket 8.
The working principle of the utility model is: the promotion air bag component (expansion core axis 2 and air bag 3 in air bag) of cylinder 1 protrudes into
Part aperture inner wall, the first air inlet 42 of compressed air pipe 4 are passed through compressed air, and air bag 3 is expanded, connect with aperture inner wall
Touching, plays sealing function；Second air inlet 52 of detection gas source tracheae 5 is passed through detection gas source, passes through the second gas outlet 51 toward zero
Part inner inflatable can detect workpiece with the presence or absence of leakage by external instrument after the completion of inflation.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the protection scope of the utility model.
