[0002] In the machining and manufacturing industries, accurate positioning and clamping of workpieces are essential to ensure product quality and improve production efficiency. Especially when dealing with large or high-precision workpieces, such as bridge packs, traditional positioning methods often lead to low production efficiency and even product quality problems due to complex operations and inaccurate positioning.

[0003] Although there are many solutions for positioning workpieces on the market, such as using fixed fixtures or manual positioning, these methods often have many limitations. For example, manual positioning is not only time-consuming and labor-intensive, but also difficult to achieve consistent and repeatable accuracy; fixed fixtures are often only applicable to workpieces of specific shapes and sizes and lack flexibility. In addition, due to the differences in the size and shape of the workpieces, as well as the need for lifting and rotating machine tools, static positioning systems cannot meet the needs of efficient and high-precision production.

[0004] Therefore, the modern machining industry urgently needs a device that can achieve fast, accurate and flexible positioning, especially for large or complex workpieces that need to be accurately positioned in three-dimensional space. The ideal positioning device should be able to adapt to workpieces of different sizes and shapes, while allowing rapid adjustment to match different processing requirements. In addition, the device should also be able to simplify the operating process, reduce manpower requirements, and improve the repeatability and reliability of positioning, thereby improving overall production efficiency and product quality.
