Automatic grinding and milling device

The utility model discloses an automatic grinding and milling device. The device comprises a support used for placing a workpiece, a workpiece positioning and clamping mechanism is arranged on the support and used for fixing the workpiece to the support, a mechanical arm is arranged on one side of the support, and the outer end of the mechanical arm is connected with an electric milling cutter device and a laser ranging device. The laser distance measuring device is used for obtaining the actual thickness of each detection point position in a to-be-ground area of the workpiece, and the mechanical arm drives the electric milling cutter device to conduct grinding and milling along the surface of the to-be-ground area of the workpiece according to the actual thickness of each detection pointposition. The robot is matched with the milling cutter and the high-precision laser, full-automatic operation is achieved, and the efficiency is high; the beat is fast, the efficiency is high, and thecost performance is high;
