Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a positioning clamping mechanism for an automobile component subassembly. Background Art

[0002] In the current industrial production field, especially in the automotive manufacturing industry, with the continuous advancement and deepening of industrial intelligence, the traditional manual operation mode is being replaced by automated or semi-automated production lines; this transformation aims to improve production efficiency, reduce costs, ensure product quality and adapt to rapidly changing market demands. The integration of automated production lines is a comprehensive process, in which automated production fixtures play a vital role. They are used to ensure the precise coordination of components in assembly, positioning, welding and other processes, and are key elements to ensure the smooth progress of the production process.

[0003] However, there are several problems with the existing fixture system:

[0004] 1. Structural complexity and space occupancy: Traditional tooling fixtures are often complex in design, which makes it difficult to arrange these fixtures in a limited or narrow working environment, limiting the flexibility of production line layout.

[0005] 2. Auxiliary accessories requirements: In order to realize the functions of the fixture, it is usually necessary to equip a large number of auxiliary components, such as stops, guide rails, floors, etc. This not only increases the complexity of the system, but also means more cost investment and potential failure points.

[0006] 3. High processing costs: Complex fixture design and numerous auxiliary parts lead to an increase in overall manufacturing costs. Each additional component needs to be designed, manufactured, purchased and installed, which will have an impact on the overall budget.

[0007] 4. Poor positioning stability: Existing fixtures perform poorly in ensuring stable positioning of parts, resulting in the quality of welding or other connection processes cannot be guaranteed. Inconsistent positioning may lead to uneven welds and unstable joint quality, thus affecting the performance and safety of the final product.

[0008] 5. Missing assembly and welding problems: As the degree of automation increases, new challenges are also brought. For example, missing assembly or welding may occur during the welding process, and traditional fixtures cannot automatically detect such errors; usually, these problems are discovered through visual inspection by workers, but this method is inefficient and prone to errors, resulting in unqualified parts flowing into the next production link, causing resource waste and potential quality risks.
