Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically a convenient disassembly tooling for welding workpieces for new energy vehicles. Background Technology

[0002] In the field of welding for new energy vehicles, tooling design plays a crucial role in production efficiency and welding quality. With the rapid development of the new energy vehicle industry, the complexity of vehicle structures and components is constantly increasing, placing higher demands on the flexibility and adaptability of welding tooling. Traditional welding tooling is usually relatively fixed, making it difficult to quickly adapt to different models and specifications of welding workpieces. This results in a significant amount of time and manpower being spent on disassembling and replacing tooling when changing welding products, severely restricting production line efficiency. Furthermore, due to insufficient tooling flexibility, it is difficult to guarantee welding quality when welding workpieces with complex shapes and high precision requirements.

[0003] Most existing welding fixtures are customized for specific products or product lines. In the context of the rapid product updates and diverse product types in the new energy vehicle production environment, it is difficult to quickly switch fixtures to adapt to the welding requirements of different products. For example, when welding battery pack casings or other key components for different vehicle models on the same production line, traditional fixtures cannot be easily adjusted or replaced. The fixed fixture structure requires complex modifications even for minor changes in product size or shape, increasing production and time costs. The installation, disassembly, and adjustment of existing fixtures often require multiple tools and involve cumbersome procedures. This not only prolongs fixture changeover time but also increases the labor intensity and error probability of operators. For instance, some fixtures require multiple bolts for fixing; during disassembly, each bolt must be loosened individually, and during installation, precise alignment and tightening are necessary, resulting in low efficiency.
