Problems solved by technology

[0002] In the airtightness test of the existing canopy, the canopy is usually manually positioned and then compressed. Since the canopy requires a circumferential seal, if the canopy is not positioned accurately or the pressing force is uneven, it may cause Sealing failure will seriously affect the test efficiency of the airtightness test of the canopy. At the same time, manual positioning may cause excessive force during the locking process of the canopy, resulting in damage to the canopy, seriously affecting the product quality of the canopy, and even causing the canopy to be damaged. Scrapping of whole parts

Abstract

The invention relates to a test fixture for the airtightness of a canopy. An airtight platform is positioned and connected to the upper surface of the base of the frame structure, and upright columns are respectively arranged at the front and back of the lower surface of the base; The pressing device presses and seals the lower edge of the canopy to be tested with the sealing rubber ring of the airtight platform; the external pressing device consists of a front pressing device, a rear pressing device and a side tensioning device; The inspection hole communicates with the inner cavity of the canopy to be tested, and the bottom of the inspection hole is connected to the shielded cover plate, which is sealed and connected to the base through the bolts arranged around the circumference; Use sealing joints and vacuum sealing joints. The canopy airtightness test fixtures are evenly distributed to ensure that the pressing force is uniform during the automatic locking process, thereby improving the sealing performance.

Description

technical field [0001] The invention relates to a jig for airtightness test of a canopy, which belongs to the technical field of jigs and tools. Background technique [0002] In the airtightness test of the existing canopy, the canopy is usually manually positioned and then compressed. Since the canopy requires a circumferential seal, if the canopy is not positioned accurately or the pressing force is uneven, it may cause Sealing failure will seriously affect the test efficiency of the airtightness test of the canopy. At the same time, manual positioning may cause excessive force during the locking process of the canopy, resulting in damage to the canopy, seriously affecting the product quality of the canopy, and even causing the canopy to be damaged. The scrapping of whole parts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a canopy airtightness test fixture, the canopy airtightness test fixture is provided ...
