Description

Technical Field

[0001] This utility model relates to the field of sealing and leak detection fixtures, specifically to a dense hole sealing mechanism. Background Technology

[0002] In the component manufacturing industry, airtightness testing is a crucial process. Current methods involve sealing all holes on the component using a sealing fixture, then filling the internal cavity with high-pressure gas. Sensors are used to monitor pressure changes, or the fixture is immersed in water to observe bubbling. However, most existing sealing fixtures use cylinders as the clamping force unit. The cylinder pressure is related to its diameter; higher pressure cylinders require larger volumes, thus demanding more installation space. For components with multiple holes in the same direction requiring sealing, the current approach involves distributing multiple plugs on a sealing plate and driving them with a cylinder. The drawback of this structure is uneven sealing pressure across each plug, easily leading to individual plug failures. Therefore, it is necessary to design a sealing mechanism specifically for densely packed multiple holes on a single side. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a dense hole-sealing mechanism that enables individual drive of each plug, ensuring the sealing pressure of each plug, and allowing the plug sealing pressure to be set according to different needs.
