Technical Field

[0001] This utility model relates to the field of piston rod machining tooling technology, and in particular to a positioning and clamping tooling for machining metal piston rods. Background Technology

[0002] The piston rod is the connecting component that supports the piston in performing work. It is mostly used in hydraulic cylinders and pneumatic cylinders. It is a moving component with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it consists of several parts: cylinder barrel, piston rod, piston, and end cap.

[0003] In actual use, the metal piston rod is positioned and clamped by the piston rod machining fixture. When the position of the metal piston rod needs to be adjusted or continuous feeding is required, the metal piston rod needs to be unloaded and the length adjusted, which affects the processing efficiency and urgently needs to be improved, thus making it inconvenient to achieve rapid adjustment.

[0004] Therefore, to address the aforementioned problem of inconvenience in achieving rapid adjustment, a metal piston rod machining positioning and clamping fixture can be designed. Activating the adjustment component can simultaneously drive two sets of guide components to rotate and adjust. The two sets of guide components can then feed the metal piston rod against the material. Furthermore, multiple sets of friction balls can reduce the frictional force between the workpiece and the clamp, thereby achieving the effect of rapid adjustment. Utility Model Content
