Description
Technical field
The present invention relates to a kind of leakage detection apparatus, particularly to a kind of charge air cooler air chamber mouth leakage detection apparatus.
Background technology
In the production process of charge air cooler, in order to ensure the quality of product, need charge air cooler is carried out air seal test, at gas
Air inlet/outlet need to be sealed sealing during close test.Air seal test employed in currently available technology is that swivel bolt method is by cylinder
Sealed gluing block swells method, it is achieved seal.There are following some shortcomings in this air seal test mode: needs operator before the test
Being screwed by the block head of every charge air cooler by hand, every screws the time about 30 seconds, significantly reduces test efficiency；Due to this
Air seal test mode is to seal charge air cooler air inlet/outlet by seal gasket, and the gas indoor at leak detection seasonal epidemic pathogens upwards pushes up, and often will
Closure fixture ejects, and easily causes the danger hurted sb.'s feelings.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, the invention provides a kind of simple in construction, reasonable in design,
The charge air cooler air chamber mouth leakage detection apparatus that test is convenient, operates safely, hunt leak effective.
The technical solution adopted for the present invention to solve the technical problems is: a kind of charge air cooler air chamber mouth leakage detection apparatus, including
Gripper shoe, the both sides of described gripper shoe are all hinged with swing arm, and the lower end of two described swing arms is equipped with claw, two described swing arms
Upper end be all hinged with connecting rod, be hinged with cross bar between two described connecting rods, the downside of described cross bar is provided with cylinder, described cylinder
The downside of piston rod and cross bar fixing be connected, described gripper shoe is provided with through hole, and described cylinder through hole from gripper shoe is worn
Crossing the downside extending to gripper shoe, the lower end of described cylinder is provided with seal disc, and described seal disc is provided with air inlet.
Use said structure, in use, the gas outlet of charge air cooler air chamber is closed, then by claw clamping radiator gas
The air inlet pipe of room, seal disc is blocked the air inlet pipe of air chamber, is then placed in water by charge air cooler, is finally passed through gas in air inlet
Whether body, observe in water and have bubble to produce；When the pressure in air chamber increases, and seal disc is attempted active force, seal disc by air inlet pipe
Under the effect of active force, cylinder being produced a power upwards, the cross bar on piston rod offsets up under the effect of this power,
Along with the skew of cross bar drives two connecting rods to produce outside active force, this active force acts directly on the upper end of swing arm, logical
Cross lever principle and produce an inside active force in the downside of swing arm, thus enhance the grasp of claw, the grasp of claw
It is directly proportional to the pressure in air chamber；Present invention effectively prevents owing in air chamber, the excessive situation about being ejected by leakage detection apparatus of pressure is sent out
Raw, reduce danger, and convenient mounting and clamping, drastically increase the efficiency of leak detection.
As preferably, described claw is the arcuate structure that the outer wall with the air inlet pipe of radiator air chamber matches.In employing
State structure so that the outer wall of claw and air inlet pipe is preferably fitted and clamping, it is ensured that the outer wall of air inlet pipe can uniform force,
Improve the clamping effect of claw.
As preferably, the length sum of described cross bar and two connecting rods is more than the spacing between two swing arm upper ends.Use
Said structure, is effectively increased the leakage detection apparatus pressure to producing in air chamber and makes the sensitivity of feedback, thus improve inspection
The efficiency of leakage.
As preferably, the upper surface of described seal disc is fixed with screw rod, and described seal disc is by the lower end of screw rod with cylinder
It is connected.Use said structure, adjusting screw rod can be carried out by the difference of the shape and structure of the air inlet pipe of air chamber, thus change close
The spacing of closing disk and cylinder lower end, carries out leak test being applicable to difform charge air cooler.
As preferably, the diameter of described seal disc lower surface is not less than the aperture of the air inlet pipe of radiator air chamber.In employing
State structure, be effectively increased the sealing property of seal disc.
As preferably, described seal disc is quality of rubber materials.Use said structure, be effectively increased the sealing of seal disc
Energy.
The present invention have simple in construction, reasonable in design, test is convenient, operation safely, the feature such as effective of hunting leak.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention；
Fig. 2 is that the use of the embodiment of the present invention is with reference to figure.
Detailed description of the invention
Below by specific embodiment, and combine accompanying drawing, technical scheme is described in further detail.
Embodiment:
A kind of charge air cooler air chamber mouth leakage detection apparatus as shown in Figure 1 to Figure 2, including gripper shoe 1, the both sides of gripper shoe 1 are the most hinged
Having swing arm 2, the lower end of two swing arms 2 to be equipped with claw 3, claw 3 is that the outer wall of the air inlet pipe 11 with radiator air chamber matches
Arcuate structure so that the outer wall of claw 3 and air inlet pipe 11 is preferably fitted and clamping, it is ensured that the outer wall of air inlet pipe 11 can
Uniform force, improves the clamping effect of claw 3.
The upper end of two swing arms 2 is all hinged with connecting rod 4, is hinged with cross bar 5, cross bar 5 and two connecting rods between two connecting rods 4
The length sum of 4 more than the spacing between two swing arm 2 upper ends, be effectively increased the leakage detection apparatus pressure to producing in air chamber and
Make the sensitivity of feedback, thus improve the efficiency of leak detection.
The downside of cross bar 5 is provided with cylinder 6, and the piston rod 7 of cylinder 6 is fixing with the downside of cross bar 5 to be connected, and gripper shoe 1 sets
Having through hole, the cylinder 6 through hole from gripper shoe 1 to extend through the downside to gripper shoe 1, the lower end of cylinder 6 is provided with seal disc 8,
Seal disc 8 is provided with air inlet 9, and the upper surface of seal disc 8 is fixed with screw rod 10, and seal disc 8 is by screw rod 10 and cylinder 6 times
End is connected, and can carry out adjusting screw rod 10 by the difference of the shape and structure of the air inlet pipe 11 of air chamber, thus change seal disc 8 with
The spacing of cylinder 6 lower end, carries out leak test being applicable to difform charge air cooler；Seal disc 8 is quality of rubber materials, seal disc
The diameter of 8 lower surfaces, not less than the aperture of the air inlet pipe 11 of radiator air chamber, is effectively increased the sealing property of seal disc 8.
In use, the gas outlet of charge air cooler air chamber is closed, then by the air inlet pipe of claw 3 clamping radiator air chamber
