[0002] A clamping device used in metal parts processing is used to secure the workpiece during machining, preventing it from rotating or moving, thereby ensuring precision and safety. The device's primary function is to clamp the workpiece, preventing it from shifting or moving during machining, thereby ensuring precision and stability. Clamping devices for metal parts processing play a crucial role in the hardware manufacturing industry, particularly in parts manufacturing, assembly, and testing.

[0003] In practical applications, hardware parts come in a variety of shapes, with flat and cylindrical shapes being common. Flat parts typically have a large flat surface area, requiring a clamping device to provide stable support and clamping force. Cylindrical parts, on the other hand, have curved surfaces, requiring a clamping device that can adapt to their shape and provide sufficient clamping force to prevent the workpiece from slipping or deforming during machining. Traditional clamping devices are often time-consuming and labor-intensive to change fixtures to accommodate workpieces of varying shapes, requiring operators to expend considerable time and effort disassembling and installing fixtures. This not only increases the operator's workload but also reduces production efficiency. Utility Model Content
