Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery tray inspection technology, and in particular to a battery tray reverse side inspection fixture. Background Technology
[0002] In the production of new energy vehicles, batteries often need to be placed and secured in battery trays. After the battery trays are produced, they need to be tested for airtightness. In existing technologies, because the back side is not as flat as the front, front-side testing is mostly used. However, leaks often appear on the back, making it difficult to observe specific leak points. Front-side testing can rely on the weight of the battery tray itself, requiring only one clamping cylinder. Reverse-side testing, on the other hand, requires a sealing frame positioned above the battery tray, necessitating multi-point clamping and sealing. Furthermore, in existing technologies, the positioning fixture is fixed, requiring a large vertical space between the fixture and the clamping mechanism for workers to easily place or remove the battery tray, and collisions with the clamping mechanism are possible during this process.
