Technical Field

[0001] The utility model belongs to the technical field of air tightness detection equipment, in particular to an air tightness detection equipment for a turbocharger housing. Background Art

[0002] Turbochargers can improve energy utilization and reduce air pollution caused by automobile exhaust. Currently, this technology is widely used and becoming increasingly mature. The performance requirements of various OEMs for turbines are constantly increasing, and thus the requirements for the airtightness of turbocharger housings are also constantly increasing.

[0003] In the prior art, special equipment is usually required for air tightness testing of a turbocharger housing. However, the turbocharger housing cannot be limited and fixed during the test, which may easily cause the turbocharger housing to deviate from its original position during the test and may easily cause damage to the turbocharger housing. Therefore, the present application proposes a turbocharger housing air tightness testing device to solve the above problem. Utility Model Content

[0008] Furthermore, the shell is made of tempered glass with good sealing performance, and the interior of the shell is set to be in a hollow state. The shell can effectively perform airtightness detection on the turbocharger shell.

[0009] Furthermore, the load-bearing plate is slidably connected to the inner wall of the shell, and the elastic support rod, the airbag and the air pressure cabin are all fixedly connected to the inner lower end of the shell, so that the load-bearing plate can effectively place the turbocharger shell.

[0010] Furthermore, the material of the limit plate is rubber with strong friction, and the two sides of the limit plate are slidably connected to the inside of the shell. The limit plate can effectively limit the two sides of the turbocharger shell.

[0011] Furthermore, the buffer protection device includes a connecting block, a rotating rod is rotatably connected to the connecting block and penetrates the connecting block, reduction wheels are fixedly connected to both sides of the reduction rod, and reduction grooves are arranged on the sides of the reduction wheel. The buffer protection device can effectively provide buffer protection for the turbocharger housing.

[0012] Furthermore, the connecting blocks are fixedly connected to both sides of the bottom of the load-bearing plate, and the two connecting blocks are symmetrically arranged, so that the connecting blocks can effectively drive the reduction wheel to move.

[0013] Furthermore, the reduction wheel is made of rubber with strong friction, and the reduction grooves are provided on both sides of the inner part of the shell. The reduction wheel can generate resistance when sliding in the reduction grooves, thereby achieving a buffer protection effect.

[0014] The utility model has the following beneficial effects:

The reduction wheel will slide in the reduction slide groove to generate resistance, thereby achieving the effect of buffering and deceleration. The turbocharger casing can be effectively protected to prevent the turbocharger casing from being damaged during detection, thereby further enhancing the practicality of the entire device.

[0036] A specific application of the present embodiment is as follows: firstly, the turbocharger housing is placed on the top of the load-bearing plate 31. The turbocharger housing will squeeze the load-bearing plate 31 and the elastic support rod 32 by its own weight. The elastic support rod 32 will shrink after being squeezed and drive the load-bearing plate 31 to descend. When the load-bearing plate 31 descends, the airbag 33 will be squeezed.

After the limiting is completed, the liquid for air tightness detection is injected into the inside of the housing 1. The air tightness of the turbocharger housing can be observed to see if it is intact. After the detection is completed, the drain pipe 2 is opened to discharge the liquid inside the housing 1. Then the exhaust valve 39 is opened. The gas in 36 will be discharged, and the pneumatic rod 37 and the limit plate 38 will return to their original positions without the drive of gas, thereby releasing the limit state on both sides of the turbocharger housing. After the turbocharger housing is removed, the elastic support rod 32 will not be squeezed any further, and the elastic support rod 32 will drive the load-bearing plate 31 to return to its original position and will not continue to squeeze the airbag 33. The airbag 33 will allow external gas to enter its interior through the intake pipe 34, so that it will return to its expanded state and be convenient for next use. It is highly practical. When the load-bearing plate 31 descends, it will drive the connecting block 41 and the reduction wheel 43 to move synchronously, and the reduction wheel 43 will slide in the reduction chute 44.
