The inflation needle 6 and the pressure gauge 7 are connected to the air pump through a connecting pipe, and the air pump is arranged on the back of the detection box 1, so as to facilitate the air supply to the inflation needle 6 through the air pump, and the pressure data during the detection process is displayed through the pressure gauge 7.

[0025] Among them, an adjustment seat 8 is fixedly installed on the inner bottom wall of the detection box 1, a detection seat 9 is fixedly installed on the top of the adjustment seat 8, a spring 10 is installed inside the detection seat 9, and a mounting groove is opened on the top of the detection seat 9. The spring 10 is fixedly connected to the detection seat 9 through the mounting groove, so that the pressure sensor 11 is supported by the spring 10 inside the mounting groove. When the detection part is placed on the top of the detection seat 9, the pressure sensor 11 can monitor it in time, and retract to the inside of the detection seat 9 under the elastic force of the spring 10.

[0029] The working principle of the above embodiment is:

[0030] When using the air tightness detection device for automobile parts, the parts are first placed on the top of the detection seat 9. After the parts apply pressure to the pressure sensor 11, the pressure sensor 11 is linked to the double-axis motor 12 to rotate. The rotation of the double-axis motor 12 drives the adjustment rod 13 to rotate, so that the movable rod 14 drives the contact block 16 on the fixed rod 15 to contact and clamp the parts. Then the electric push rod 3 drives the movable frame 4 to descend and makes the sealing gasket 5 contact with the opening part of the part. The inflation needle 6 extends to the inside of the part to inflate. The pressure gauge 7 displays the value in real time. After stopping the inflation, the value of the pressure gauge 7 is observed to judge whether the air tightness is qualified.
