Problems solved by technology

[0003] At present, the existing leak detection methods for testing the sealing performance of kettles are mostly manual gas detection, artificial air bubble detection or manual water injection detection, which will have problems such as low degree of automation, high labor intensity, and poor precision.
Artificial gas detection equipment seals the top and bottom of the kettle, and manually detects whether there is gas leakage. The detection results are not accurate and there are large errors. If the kettle is slightly leaky, it is often difficult to detect; the artificial air bubble detection method is to immerse the sealed kettle in water. , to detect whether there are bubbles, the process is more complicated, and the soaked kettle needs to be cleaned before it can be sold; there is also a manual water injection detection method, which is to fill the kettle with water and observe whether the kettle is leaking, so that it is impossible to detect the slight leakage of the kettle Happening

Abstract

The invention discloses a leak detection fixture and a leak detection device. The leak detection fixture comprises a fixture upper press plate, an airbag support seat, an airbag and a fixture holder. The fixture upper press plate is fixed on the upper end of the airbag support seat. The lower end of the airbag support seat is fixed on the fixture holder. The airbag is arranged in the airbag support seat. The airbag is sleeved on the body of a kettle. The upper part of the airbag is arranged at the joint of the fixture upper press plate and the airbag support base. The lower part of the airbag is arranged at the joint of the airbag support seat and the fixture holder. The airbag support seat is provided with a blow hole which is connected with an air source. The fixture holder is provided with a vacuumizing hole connected with a suction pump. The kettle is arranged in the middle groove of the leak detection fixture. The leak detection fixture provided by the invention has the advantages of simple and practical structure and good sealing property, and can be specifically used for detecting the sealing property of the key part of the kettle (such as the part between the kettle body and the kettle bottom), namely the sealing of the lower part of the kettle.

Description

technical field [0001] The invention relates to the technical field of seal detection, in particular to a leak testing fixture of leak testing equipment, and also to a leak testing equipment including the leak testing fixture. Background technique [0002] As we all know, in the field of kettle manufacturing industry, the body and the bottom of the kettle are mostly welded or directly installed together. If water leakage occurs between the body and the bottom of the kettle during use, the consequences will be serious. Therefore, before the kettle enters the market , It is necessary to test the tightness of the kettle to ensure that there is no leakage between the body and the bottom of the kettle. [0003] At present, the existing leak detection methods for testing the sealing performance of kettles are mostly manual gas detection, artificial air bubble detection or manual water injection detection, which will have problems such as low degree of automation, high labor intens...
