Description

technical field [0001] The invention relates to the technical field of airtightness inspection of mechanical parts, in particular to an airtightness inspection device and method for a test piece. Background technique [0002] As we all know, in order to ensure the normal operation of various parts of the car, higher requirements are put forward for the airtightness of the car box. However, the casting molded box body inevitably has holes in the casting process. Even if the box body is tested and passed after casting, after it is machined, the exposed holes after its internal processing will cause the box body to leak. [0003] The traditional airtightness test method is to manually press the machined box in water, and observe whether there are bubbles formed by gas overflow in the water to judge the airtightness. This method is time-consuming, laborious and the test results are different from The experience of the tester is closely related, especially, the remaining burrs a...
