[0002] The drive axle is an important component of the automobile chassis. It is the last link in the transmission system. It is responsible for further processing the power transmitted from the engine through the drive shaft or directly from the transmission and finally transmitting it to the drive wheels. In order to ensure that the drive axle does not leak internal lubricants or invade external pollutants under actual working conditions, ensure the safe operation of the vehicle and extend the service life of components, traditional drive axles need to be tested for air tightness after production and processing. In the process of drive axle air tightness testing, drive axle air tightness test equipment needs to be used.

When the utility model is in use, through the installation of the air outlet bin and the shell, when the tested drive axle is moved upward by the hoisting equipment and removed from the test liquid inside the immersion tank, as the fan in the shell is started, the air outlet bin can air-dry the suspended drive axle, so that the water stains remaining on the outer surface of the drive axle after the test can be quickly dried, avoiding the water stains remaining on the surface of the drive axle during the outward movement after the test to pollute the external working environment, thereby improving the practicality of the drive axle air tightness test equipment.

[0020] like Figure 1 As shown, a gas transmission mechanism 2 for transmitting gas to the inside of the detected driving axle is arranged outside the immersion pool 1, and a plurality of connecting hoses 3 are arranged on the gas transmission mechanism 2. With the use of the detection equipment, when one end of the connecting hose 3 is connected to the air inlet of the detected driving axle, the detected driving axle will enter the inside of the immersion pool 1 through the external lifting equipment and be immersed in the detection liquid in the immersion pool 1. With the start-up of the gas transmission mechanism 2, the staff can observe whether there is gas escaping from the detected driving axle in the water by the bubbling method, so as to achieve the purpose of detecting the air tightness of the driving axle.

[0021] like Figure 2 and Figure 3As shown, multiple groups of air outlet holes 6 are arranged on the air outlet bin 4, multiple groups of connecting pipes 7 are arranged on the air outlet bin 4, multiple groups of fans 8 are arranged inside the shell 5, and the air inlet end of the fan 8 extends to the outside of the shell 5, a heating box 9 is fixedly arranged inside the shell 5, a heating element 11 is arranged around the inside of the heating box 9, and the air outlet end of the fan 8 extends to the inside of the heating box 9, a pipe body 10 is arranged on the heating box 9, and one end of the connecting pipe 7 is connected with one end of the pipe body 10. When the drive axle is tested, it is removed from the test liquid in the immersion tank 1 by external lifting equipment and moved to the middle of the two groups of air outlet bins 4 on the immersion tank 1. With the start-up of the fan 8 in the shell 5 and the heating element 11 in the heating box 9, after the fan 8 is started, its air inlet end will absorb the air outside the shell 5 and pass through its outlet The gas end delivers the sucked gas to the heating box 9, and the heating element 11 is started, which can heat the air entering the heating box 9.

Through the installation of the air outlet bin 4 and the shell 5, when the detected driving axle is moved upward by the hoisting equipment and removed from the detection liquid inside the immersion tank 1, as the fan 8 in the shell 5 is started, the air outlet bin 4 can air-dry the suspended driving axle, so that the water stains remaining on the outer surface of the driving axle after the detection can be quickly air-dried, so as to avoid the water stains remaining on the surface of the driving axle during the outward movement of the driving axle after the detection from polluting the external working environment, thereby improving the practicality of the driving axle air tightness test detection equipment. With the use of the detection equipment, when one end of the connecting hose 3 is connected to the air inlet of the detected driving axle, the detected driving axle will enter the interior of the immersion tank 1 through the external hoisting equipment and be immersed in the detection liquid in the immersion tank 1. With the start of the air transmission mechanism 2, the staff can observe whether there is gas escaping from the detected driving axle in the water by the bubbling method, so as to achieve the purpose of detecting the air tightness of the driving axle. After the moving bridge test is completed, and it is removed from the test liquid in the immersion tank 1 by external lifting equipment and moved to the middle of the two sets of air outlet bins 4 on the immersion tank 1, with the start of the fan 8 in the shell 5 and the heating element 11 in the heating box 9, after the fan 8 is started, its air inlet end will absorb the air outside the shell 5, and transport the absorbed gas to the heating box 9 through its air outlet end. The start of the heating element 11 can heat the air entering the heating box 9, and as the fan 8 continues to transport air into the heating box 9, the air heated by the heating box 9 is The air will enter the air outlet bin 4 through the pipe body 10 and the connecting pipe 7, and finally be blown evenly onto the drive axle through the multiple groups of air outlet holes 6 provided on the air outlet bin 4, so that the remaining water stains on the drive axle can be quickly dried with the blowing of heated air, thereby avoiding the pollution of the external working environment by the water stains remaining on the surface of the drive axle during the outward movement after the detection, thereby improving the practicability of the drive axle air tightness test detection equipment.
