[0002] As the production of special-purpose vehicles and special engineering vehicles develops towards small batches and diversification, in the development and manufacturing process of new projects, the use of flexible and modular combination tooling to replace traditional special tooling and non-standard tooling can not only shorten the design and manufacturing time, but also can be used repeatedly, saving costs, which is a very economical and practical choice. In addition, the flexible and modular combination tooling used in the automobile production process has the following characteristics: economy, flexibility, inclusiveness, repeatability and durability, and the traditional flexible and modular combination tooling can also be equipped with hydraulic, pneumatic, manual clamping and other forms of use.

[0003] The CNC fixtures on the existing flexible and modular combination tooling on three-axis or four-axis machine tools are mostly connected to the combination tooling by welding. When it is necessary to perform CNC processing on battery boxes, energy storage battery boxes and various profiles on new energy vehicles, the staff needs to dismantle the combination tooling on the machine tool for replacement so that the machine tool can process different parts of the car. The replacement process is cumbersome, and the combination tooling will be damaged by wear, rust and other damages after long-term use. The replacement or maintenance cost of the combination tooling is high. At the same time, the existing flexible and modular combination tooling cannot be equipped with hydraulic cylinders, various cylinders, and manual clamping to assist in clamping the product.
