Technical field
The present invention relates to field of automobile, more particularly to a kind of hole sealing device for airtight detection.
Background technique
The molding of automobile rear axle housing is generally divided into casting bridge shell and welding bridge hull, in the fabrication process inevitably
Blow hole (sand holes) or weld blowhole (failure welding) are generated, this two kinds hereinafter referred to as manufacture bad, undesirable major consequences
It is exactly oil leak.Therefore in the manufacturing process of axle housing, air-leakage test is a necessary production process, and testing principle is substantially
It all uses and fills compression air detection.
The air-leakage test the relevant technologies of axle housing at present, Major Difficulties be automobile axle housing master subtract mounting hole bore size compared with
Greatly, with the difference of vehicle bridge model, main to subtract mounting hole be also to change accordingly with model, general bore size 200~
500mm or so.Since aperture is excessive, compressive load per unit area is big accordingly, and how to seal up this macropore also just becomes in industry
A big difficulty.
Ordinary flat platen, sealing surface mounting O-shaped or planar seal ring are mostly used in industry at present, in the intermediate peace of platen
A screw rod is filled across platen, connects a cross-arm using screw rod end.When detection, platen is placed at Work piece sealing position
(axle housing), cross-arm protrudes into workpiece, then rotates an angle, tangles workpiece lumen using cross-arm, bar thick stick is recycled to rotate silk
Bar, until locking.
Above-mentioned sealing technique has the disadvantage in that
1. locking screw passes through sealing cover, a leakage point is increased；
2. bar thick stick is too long, generally longer than 1 meter, inconvenient for operation, operator's large labor intensity；

The structural schematic diagram of workpiece to be sealed.
Hole sealing device provided in an embodiment of the present invention for airtight detection, including platen 1 and sealing ring 2.
Platen 1 is made of integrally formed chassis 11 and pillar 12, and the diameter of pillar 12 is less than the diameter on chassis 11, pillar
12 bottom end and chassis 11 are integrally formed, and the top of pillar 12 is equipped with step 121；The chassis 11 is equipped with mounting groove 111.
The sealing ring 2 is fixed in mounting groove 111；The sealing ring 2 is inflatable structure；Mounting groove 111 is equipped with
Air inflation nozzle for being connected to sealing ring 2.
The use process of hole sealing device provided in an embodiment of the present invention for airtight detection includes two steps:
The first step, platen 1 are fixed；Pillar 12 is inserted into the hole of workpiece 3 to be sealed, and step 121 is stuck in workpiece 3 to be sealed
Side, chassis 11 are located at the other side of workpiece 3 to be sealed；
Second step, sealing ring 2 are inflated；By air inflation nozzle to sealing ring 2 inflate, sealing ring 2 expand after, filling platen 1 with
Gap between workpiece 3 to be sealed, the final sealing realized to 3 hole of workpiece to be sealed.
Refering to fig. 1 and Fig. 2, specifically, step 121 includes two forward spiral steps 121 in inclined-plane.
The depressed area 31 of step 121 and workpiece 3 to be sealed is opposite, and pillar 12 is inserted into the hole of workpiece 3 to be sealed, rotates
Chassis 11 makes spiral step 121 be transferred to the inside of workpiece 3 to be sealed, and final and workpiece 3 to be sealed is in close contact and fixes,
At this point, and without having to absolute clamping, it is therefore an objective to do not allow platen 1 too many because ejecting in gas pressure process due to fall, be actually
One dropping mechanism.
Refering to Fig. 5 and Fig. 6, the sealing ring 2 includes fixed part 21 and flexible part 22, and the fixed part 21 is mounted on installation
In slot 111；In unaerated, flexible part 22 is in inner concavity, and after inflation, flexible part 22 is in outer gibbosity.
The width of the mounting groove 111 is equal to the width of fixed part 21；In unaerated, the depth of the mounting groove 111
Greater than the height of sealing ring 2, make in unaerated, sealing ring 2 will not be leant out out of mounting groove 111, to reduce in installation process
Abrasion to sealing ring 2.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
