Abstract

The invention discloses a leak test device for the sealing performance of automobile engine parts cavity, which comprises a base, a part cavity, a water pump, an air pump and a valve. platform, and the first detection paper is glued on the top of the placing platform, the inner side of the placing platform is connected with the first threaded rod and the second threaded rod, and the surface of the first threaded rod is fixed with the first helical gear, so The inner side of the side plate is provided with an air bag, and the right side of the air bag is connected with a second detection paper, the upper surface of the placing table is provided with a first slot, and the upper surface of the top plate is provided with a second slot. The leak test device for cavity sealing of automobile engine parts, through the use of the first threaded rod and the second threaded rod, makes the limiting rod leak test cavity on the surface of the first threaded rod and the second threaded rod perform limit extrusion , which facilitates the fixing of the leak test cavity and improves the stability of the leak test.

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, ...
