[0002] Pipe fittings are a collective term for components in a piping system used for connection, control, direction change, flow diversion, sealing, and support. Materials include steel and plastics, with steel pipe fittings being specifically made of steel. The processing of steel pipe fittings includes cutting, forming, machining, connection, heat treatment, surface treatment, assembly, and inspection. Cutting primarily involves cutting the pipe to the required length; forming changes the shape of the pipe, such as bending, bulging, necking, flanging, and punching; machining involves precision machining of the pipe ends or specific areas, such as turning end faces, chamfering, threading, drilling, and milling; connection connects multiple pipe fittings or other components; heat treatment improves mechanical properties according to material and requirements; surface treatment enhances corrosion resistance, wear resistance, and aesthetics; and assembly and inspection assemble the processed pipe fittings with other components into the final product and perform quality checks.
[0003] During the cutting and processing of steel pipe fittings, a clamping device is needed to hold and secure the pipe. Existing technologies mainly use bench vises and chucks for clamping and securing. However, bench vises and chucks clamp the pipe from the outside, which can easily cause scratches or wear on the outer wall of the pipe. Furthermore, some pipes have thin walls, and external clamping can easily compress the pipe, leading to deformation. Therefore, it is necessary to design a clamping device for steel pipe fitting processing that provides internal fixation. Utility Model Content
