Abstract

The present invention relates to the pipe fitting performance detection equipment manufacturing technology field, in particular to an automobile intake pipe air tightness detection device and a detection method. The device comprises a rack, a water tank, an elevating device and a detection bench, and also comprises a gas source interface and a control device. The detection bench comprises a clamp arranged on a pedestal, one end of the clamp is equipped with a plug, and the other end is equipped with an inflation device. The inflation device is communicated with the gas source interface via a reducing valve, an elevating hydraulic cylinder is connected above the inflation device, and the inflation device moves up and down under the driving of the elevating hydraulic cylinder. The control device is electrically connected with the elevating device, the inflation device and the elevating hydraulic cylinder separately. The air tightness detection device of the present invention is reasonable in structure and high in detection efficiency, guarantees the processing quality of an intake pipe, realizes the automatic control of a whole process, realizes the air tightness detection by being equipped with a pressure sensor and the vent valve and without needing to be immersed in the water tank, enables the suitable range and the practicality to be improved, and also realizes the air tightness automatic determination.

Description

technical field [0001] The invention relates to the technical field of pipe fitting performance detection equipment manufacturing, in particular to an air-tightness detection device and a detection method of an automobile intake pipe. Background technique [0002] In the production of automobile air intake pipes, the air intake pipes are welded by multiple pipe bodies and bases. Leakage points are prone to occur at the pipe body welds and are difficult to find, or they are burned through during welding, so air tightness testing is required. It is usually done manually, which has low efficiency, low detection accuracy, and greatly reduces production efficiency. In addition, manual inspection is not only labor-intensive, but also unqualified products will enter the next process due to work omissions, which will eventually affect the overall quality of the engine. Therefore need a kind of automobile intake pipe air tightness detection equipment to solve the above problems. C...
