A nanometer coating milling cutter suitable for high speed machining

Abstract

This utility model discloses a nano-coated milling cutter suitable for high-speed machining, including a base, a support frame, a first transmission rod, a docking cylinder, a coated milling cutter, and an emergency stop transmission mechanism. The base is fixed on an external machine tool, the support frame is fixed on the top of the base, the first transmission rod is rotatably connected to the center of the support frame, and the docking cylinder is coaxially fixed to the top of the first transmission rod. The beneficial effects of this utility model are: In this utility model, by setting an emergency stop transmission mechanism, the ratchet is driven to rotate through the second transmission rod, and the pawl engages with the ratchet, thereby enabling the linkage disc to move synchronously with the ratchet. The second transmission rod drives the coated milling cutter to rotate, realizing the milling operation on the workpiece. When an emergency stop is required, the limiting plate abuts against the pawl, thereby separating the pawl from the ratchet. At this time, the first transmission rod loses power, and because the inertia of the first transmission rod and its connecting components is small, the coated milling cutter can stop suddenly.
