The invention relates to the technical field of numerical control machine tools, and discloses a tool bit replacing device for numerical control cabinet machining. The tool bit replacing device comprises a replacing cabinet, an air cylinder is fixedly mounted on the bottom surface of the replacing cabinet, a driven gear is fixedly mounted at the output end of the air cylinder, and a rotating plateis fixedly mounted at the top end of the output end of the air cylinder; and a placing pipe is fixedly mounted on the top surface of the rotating plate, and a transmission device is fixedly mounted at the top end of the replacing cabinet. The top end of a placing pipe drives a top plate to move upwards to push a jacking rod upwards, the jacking rod is clamped into a receding groove when moving upwards, and therefore clamping rods are driven to move towards the side away from the center of a main shaft, the two clamping rods loosen a tool bit and enable the tool bit to fall into the placing pipe, and therefore the too
