[0002] Ring parts usually have a thin thickness, and are widely used in various mechanical equipment. In the manufacturing process, the ring parts often need to be machined on the end face and polished on the inner and outer rings to ensure the dimensional accuracy and surface quality. However, due to the thin-walled characteristics of the ring parts, clamping positioning is required during the machining process to prevent displacement or deformation of the parts during machining. The existing clamping method is usually to clamp the parts directly with the jaw head to fix their position for subsequent machining.
