Problems solved by technology

[0002] ​The air tightness test of parts is often encountered in industrial production. At present, the air tightness test of parts is mostly manual visual inspection method, that is, put the part into the liquid to inflate, and then observe whether the outer surface of the part is There are air bubbles leaking; in addition, there are some special mechanical testing equipment, but they are not perfect and mature. The main aspects are that the testing results are not accurate enough, the installation sealing is not enough, and the parts installation protection is not enough, which leads to inaccurate measurement results. Accurate, and the workpiece is damaged during the measurement process, etc.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a component air tightness detection device and a detection method thereof. Background technique [0002] ​The air tightness test of parts is often encountered in industrial production. At present, the air tightness test of parts is mostly manual visual inspection method, that is, put the part into the liquid to inflate, and then observe whether the outer surface of the part is There are air bubbles leaking; in addition, there are some special mechanical testing equipment, but they are not perfect and mature. The main aspects are that the testing results are not accurate enough, the installation sealing is not enough, and the parts installation protection is not enough, which leads to inaccurate measurement results. Accurate, and the workpiece is damaged during the measurement process. In view of the above problems, the applicant has developed a part air tightness detection de...
