Description

technical field

[0001] The invention relates to the technical field related to automobile engines, in particular to a leak test device for the cavity sealing of automobile engine parts. Background technique

[0002] The automobile engine is the most important power source of the automobile, and it occupies a leading position in the automobile. During the processing from the automobile to the engine, it is necessary to use a leak test device to detect the cavity of the engine parts in order to remove unqualified parts. The chamber can improve the production quality of the automobile engine, but the existing leak test device for the sealing of automobile engine parts still has some problems, such as:

[0003] It is inconvenient to effectively limit the test cavity when the existing leak test device is in use, resulting in the instability of the cavity during the leak test and affecting the accuracy of the leak test. The existing leak test device The leak test effect is poor, ...
