Water immersion type automobile exhaust pipe air tightness detection device and detection method thereof

Abstract

The invention relates to a water immersion type automobile exhaust pipe air tightness detection device disclosed by the present invention, which comprises a water immersion chamber for immersing an exhaust pipe, and a first plugging block and a second plugging block for plugging two ends of the exhaust pipe, a support plate is connected below the first plugging block, a first driving plate is fixed at the lower end of the support plate, the right side of the second plugging block is connected with a control plate, the lower portion of the control plate is connected with a second driving plate through a sliding connection mechanism, and a movable block is slidably mounted on the right side of the control plate. According to the water immersion type automobile exhaust pipe air tightness detection device, the exhaust pipe is controlled through the first plugging block and the second plugging block, rapid detection of the air tightness of the exhaust pipe can be realized through a water immersion type detection mode, air leakage can be directly observed even if air leakage is found at a joint, the air tightness of the subsequent exhaust pipe is not greatly influenced, and electrical equipment of the device is arranged above the water immersion chamber, so that subsequent normal work is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipe detection, in particular to a water-immersed automobile exhaust pipe air tightness detection device and detection method. Background technique [0002] Automobile exhaust pipe is a necessary equipment for automobile exhaust treatment and noise reduction. When the exhaust pipe leaks, its noise reduction effect will be reduced. After production, the airtightness detection device can be used to test its tightness, but There are also some deficiencies in the existing air tightness detection device in use: [0003] Most of the existing air tightness detection devices judge the airtightness of the exhaust pipe by means of pressure drop, but when there is a gap in the plugging port, the pressure drop will also occur, which will affect the accuracy of subsequent detection results The publication number is CN212931832U disclosed a kind of automobile exhaust pipe airtightness detection devi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a water-immersed automobile exhaust pipe airtightness detection device and detection method to solve the problem of the existing airtightness detection device in the market when the exhaust pipe is detected by the above-mentioned background technology. Most of them judge the tightness by means of pressure drop, but when there is a gap in the plugging port, pressure drop will also occur, which will affect the accuracy of subsequent test results.
