Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of rim welds, in particular to an air tightness detector for automobile steel rim welds. Background Technique

[0002] The air tightness detection of automobile steel rim welds is an important link to ensure that there is no gas leakage during the use of the tire and rim assembly. It is an important part of the production quality management of automobile enterprises and also an important business component of the automobile maintenance industry.

[0003] At present, the conventional detection method is to inject gas into the tire through the valve nozzle during the detection process, and manually apply soapy water or other leak detection agents evenly on the weld to observe whether there are bubbles generated to further confirm the leakage point. It has the advantages of low cost and easy observation of the leakage point. However, this also makes the detection process highly dependent on manual operation and has a low degree of automation, which will affect the overall production efficiency in industrial production.
