Numerical control machine tool cutter cleaning device

The utility model relates to the technical field of numerical control machine tool equipment, in particular to a numerical control machine tool cutter cleaning device. According to the cutter cleaning device, cutters can be brushed and rotated up and down in a reciprocating mode, so that the cutters are cleaned more thoroughly, and the cleaning efficiency and effect of the cutters are improved. The device comprises a box body, a water inlet pipe, a water outlet pipe and the like, and a water outlet pipe is arranged at the lower part of the box body. An output shaft of a motor drives a two-way screw rod to rotate, so that a nut is driven to continuously move up and down in a reciprocating mode, a brush plate is driven to continuously brush a cutter, meanwhile, the two-way screw rod drives a driving gear to rotate, five driven gears are driven to rotate, and then the cutter rotates; in this way, the cutter can be continuously brushed up and down and rotated during cleaning, so that the cutter is cleaned more th
