Description

Technical Field

[0001] This invention relates to a multi-size battery pack cover pressing equipment, belonging to the field of automotive manufacturing technology. Background Technology

[0002] With the country's control over carbon emissions, the proportion of new energy vehicles is increasing. The rapid, efficient and stable production of core components such as battery packs is of great significance to product performance and enterprise production capacity.

[0003] The battery pack cover plays a crucial role in the sealing performance of the battery pack. Due to the presence of the sealing gasket, the current process of directly tightening the bolts results in a situation where the bolts are tightened at the beginning but loosened later, leading to substandard sealing after tightening. For this reason, the process needs to be changed to a method of first compressing the entire pack and then tightening the bolts. Summary of the Invention
