By adopting the structure, when the device is used, the air outlet of the intercooler air chamber is closed, the clamping jaw is clamped with the air inlet pipe of the radiator air chamber, the sealing disc blocks the air inlet pipe of the air chamber, the intercooler is placed in water, and finally, air is introduced into the air inlet hole to observe whether bubbles are generated in the water; when the pressure in the air chamber is increased, the air inlet pipe generates acting force on the sealing disc, the sealing disc generates upward force on the air cylinder under the action of the acting force, the cross rod on the piston rod deflects upwards under the action of the acting force, the two connecting rods are driven to generate outward acting force along with the deflection of the cross rod, the acting force directly acts on the upper end of the swing arm, and inward acting force is generated on the lower side of the swing arm through the lever principle, so that the gripping force of the jaws is enhanced, and is in direct proportion to the pressure in the air chamber; the invention effectively avoids the situation that the leak detection device is ejected out due to overlarge pressure intensity in the air chamber, reduces the danger, is convenient to clamp and greatly improves the leak detection efficiency.
Preferably, the clamping jaws are of arc structures matched with the outer wall of the air inlet pipe of the air chamber of the radiator. By adopting the structure, the clamping jaw is better attached and clamped with the outer wall of the air inlet pipe, the outer wall of the air inlet pipe is guaranteed to be evenly stressed, and the clamping effect of the clamping jaw is improved.
Preferably, the sum of the lengths of the cross rod and the two connecting rods is larger than the distance between the upper ends of the two swing arms. By adopting the structure, the sensitivity of the leak detection device for feeding back the pressure generated in the air chamber is effectively improved, so that the leak detection efficiency is improved.
Preferably, a screw is fixed on the upper surface of the sealing disc, and the sealing disc is connected with the lower end of the cylinder through the screw. Adopt above-mentioned structure, the shape structure's of the intake pipe that can pass through the air chamber difference comes adjusting screw to change the interval of sealed dish and cylinder lower extreme, carry out leak hunting test with the intercooler that is applicable to different shapes.
Preferably, the diameter of the lower surface of the sealing disk is not smaller than the diameter of the air inlet pipe of the air chamber of the heat radiator. By adopting the structure, the sealing performance of the sealing disc is effectively improved.
Preferably, the sealing disc is made of rubber. By adopting the structure, the sealing performance of the sealing disc is effectively improved.
The invention has the characteristics of simple structure, reasonable design, convenient test, safe operation, good leak detection effect and the like.
