Automatic scrap cleaning device for numerical control machine tool

The utility model relates to the technical field of numerical control machine tool chipping cleaning, in particular to an automatic chipping cleaning device for a numerical control machine tool, which comprises a machine tool body, a collecting box is slidably connected in the machine tool body, a working table is welded on the inner wall of the machine tool body, and a rectangular groove is formed in the surface of the working table. A cooling liquid box is welded to the bottom end of the workbench, and a screening device for separating cooling liquid from chippings is arranged at the bottom end of the workbench. Through mutual cooperation of all structures in the screening device, the motor drives the rotating shaft to rotate, the rotating shaft drives the filter screen to rotate clockwise through the rotating plate frame, and the rotating filter screen rotates and moves out chippings falling into the fixed arc groove, so that a mixture of cooling liquid and the chippings in the fixed arc groove is screened
