Connect；Manual rotation's eccentric handle during work, connecting plate is driven to pull mandrel to shorten the distance between upper and lower cover plates, rubber stopper production
Raw compression and to outside rising, blocks the inlet, outlet of circumferential sealing charge air cooler air chamber；When rubber stopper and charge air cooler air chamber
Between inlet, outlet during frictional force deficiency, rubber stopper easily comes off or collapses, gently then injuring part, heavy then injure the person, exists
Severe compromise；Be not suitable for high pressure detection, it is impossible to meet the product quality of customer requirement.
Inspection of hermetic seal fixture monomer comes off or collapses, and is one of the dominant failure mode of charge air cooler water inspection, industry difficult point.
The content of the invention
Anti- the utility model discloses a kind of inspection of hermetic seal fixture collapses de- structure, to solve inspection of hermetic seal in the prior art
The problems such as fixture monomer comes off or collapses.
The utility model include handle, eccentric block, connecting plate, cover plate, rubber stopper, tubular bracket, pipe joint, hollow shaft,
Hook plate；Tubular bracket includes upper flange, lower flange；Hook plate has long lumbar hole；Hook plate one end is hingedly connected to tubular bracket laxative remedy
Lan Shang；After being articulated and connected, when hook plate rotates down, an angle be present, hook plate projects in the horizontal direction under the angle, hook plate
Non-articulated end is projected on the circumference of air chamber bore；Hook plate non-articulated end edge is small to air chamber bore direction projection during extreme position
In air chamber bore；Hollow shaft includes pipeline section, boss；The pipeline section of hollow shaft passes through the long lumbar hole of hook plate, the boss and hook of hollow shaft
Plate is in contact；Tubular bracket, rubber stopper, cover plate to it is lower and on be sequentially arranged in hollow shaft, be slidably matched with hollow shaft；Covering
Plate top, connecting plate are articulated and connected with eccentric block；Connecting plate is fastenedly connected with hollow shaft；The pipeline section upper end of pipe joint and hollow shaft
Portion is fastenedly connected；When inspection of hermetic seal fixture is put into taking out, hook plate is swung down to extreme position；During sealing state, hollow shaft
Lower boss lifts hook plate into horizontality, and hook plate non-articulated end edge, into and out of in stomata elbow, limits rubber stopper in charge air cooler
Collapse depigmentation effect；Detection terminates, and eccentric block loosens, and mandrel, rack sinking, hook plate are rotated down recovery initial bit by Gravitative Loads
Put.
The scheme of optimization is：There is a stop surface on eccentric block；Rotating eccentric block makes stop surface contact locking with cover plate.
In charge air cooler sealing test, while two the utility model of application are as closure；Hook plate is cold in being symmetrically mounted on
Device into and out of in stomata elbow；During work, the pipe joint connection fluid sealant leather sheath of first closure；The pipe of second closure connects
Head connection compressed air connecting tube.
Good effect of the present utility model is：Good airproof performance, using hook plate and air chamber wall, sealing inspection is effectively evaded
Test fixture monomer causes because being filled with gases at high pressure, rubber stopper and the intraoral wall friction power deficiency of air chamber inside charge air cooler when in use
The potential safety hazard is collapsed, substantially increases the security of fixture.
