Combined type side milling fixture

[ field of technology ]

The utility model relates to the technical field of milling auxiliary tools, in particular to the technical field of composite side milling clamps.

[ background Art ]

Milling refers to cutting a workpiece using a rotating throw-away tool, and is a highly efficient machining method. In operation, the tool rotates (performs main movement), the workpiece moves (performs feeding movement), and the workpiece can be fixed, but the tool which rotates must also move (simultaneously performs main movement and feeding movement). When the shaft parts are processed on a milling machine, auxiliary tools such as V-shaped blocks are generally adopted. However, for the processing of stepped shafts, clamping is inconvenient due to the presence of steps. For this reason, a new type of milling fixture for stepped shafts is required.
