In the process of realizing the present utility model, the inventor found that the existing technology has at least the following problems:

At present, the welding production lines in the automobile industry are developing rapidly in the direction of high automation, flexibility and high cycle time. However, excessive automation level often means high investment and high operating costs, which is a huge burden for the operation of the enterprise itself, especially For small and medium-sized automobile companies, the iteration rate of production lines and models is low, and the scale of production capacity is small. Manual production lines with low to medium cycle times and low costs still have irreplaceable cost advantages.

In the development of vehicle model production lines, in order to reduce costs, manual production lines are usually used for lower-level sub-assemblies. Considering that the flexibility of manual fixtures is poor, it is often necessary to replace the fixture as a whole when the model is iterated. When the model is eliminated, most of the fixture mechanism loses its function. To improve this situation, reduce the development cost and cycle of manual fixtures.

1. At present, in traditional automobile manufacturing OEMs, the side panel production lines usually use highly automated flexible lines, and the fixtures are switched as a whole, which requires a large area and high cost investment. 2. Traditional enterprises adopt automated partial switching solutions, which occupy a large area and require high investment costs. 3. Traditional manual line side panel fixtures can usually only match a single model. During model iteration and new development, manual fixtures are often switched as a whole, resulting in higher costs and cycles.
