[0002] The metal frame workpiece includes a frame base, a frame upper frame, and a vertical plate installed between the frame base and the frame upper frame. In current industrial production, especially in the manufacturing process of metal frame workpieces (such as triangular, square and symmetrical polygonal frames), the assembly and positioning of the frame is a critical and complex process. Traditional frame assembly methods often rely on a large amount of manual operations, which not only increases labor intensity, but also easily introduces human errors, making it difficult to ensure the frame size accuracy and assembly quality.

[0003] Existing automation equipment and robotic systems are often designed for frames of specific shapes and sizes. Different fixtures and tooling need to be customized for frames of different shapes and sizes, which increases equipment costs and debugging difficulties. Existing solutions are still insufficient in dealing with diverse production needs, especially when it is necessary to quickly switch between frames of different models and specifications, which lack sufficient flexibility and adaptability.

The second clamping fixing member 38 is provided with a fifth clamping surface 41 and a sixth clamping surface 42 for clamping on the side of the joint portion, and a second supporting surface 40 for supporting on the bottom of the plane portion.
