A copper valve milling machine turning fixing device

Abstract

This utility model provides a copper valve milling machine turning and fixing device, belonging to the field of copper valve milling machine turning technology. It includes a three-jaw chuck with three sets of sliding grooves. Limiting strips are fixedly connected inside the sliding grooves, and fixing jaws adapted to the sliding grooves are slidably connected to the limiting strips. The fixing jaws have limiting grooves adapted to the limiting strips. Multiple sets of connecting parts are installed inside the fixing jaws. Connecting columns are fixedly connected to the ends of the connecting parts, and connecting frames are fixedly connected to the ends of the connecting columns. Extrusion rollers are fixedly connected to the connecting frames. Extrusion parts for extruding the connecting parts are also installed inside the fixing jaws. This utility model uses multiple sets of extrusion rollers to extrude and fix the copper valve, increasing the contact area between the copper valve and the extrusion rollers, improving the stability of the copper valve fixing, and solving the problem of unstable copper valve fixing caused by the small contact area between the fixing jaws and the copper valve in the prior art.
