MECHANISM FOR BLOWING CHIPS OF NUMERICAL CONTROL MACHINE TOOLS

The present patent relates to the technical field of machine tool auxiliary mechanisms, and in particular to a mechanism for blowing chips of numerical control machine tools, including a machine tool body. A workbench is disposed on the machine tool body, rotating grooves are arranged at the positions of the machine tool body on both sides of the workbench, and a chip outlet groove is disposed on the other side of the machine tool body; threaded rods are rotatably connected in the rotating grooves, and a support frame is threadedly connected to the threaded rods; and several first spray heads are fixedly connected to the support frame, a sliding groove is disposed on the support frame, and a conversion mechanism is slidably connected in the sliding groove. According to the present invention, the first spray heads blow air to the workbench through an external fan, thereby blowing off iron chips from a table top of the workbench, then blow air into T-shaped grooves on the workbench through the conversion mechanism, thereby blowing off the iron chips from the T-shaped grooves, which ensures the cleaning of the workbench after processing is completed and accelerates the cleaning speed of the workbench, thereby improving the overall processing speed and reducing the labor intensity of workers.
