The utility model relates to an automatic exhaust type gear pump device for a numerical control machine tool. The automatic exhaust type gear pump device comprises a gear pump body and a motor connected above the gear pump body, a discharge port of the gear pump body is provided with a three-way joint; one path of the three-way joint is communicated with the cutter cooling end, and the other path is sequentially communicated with an electromagnetic valve and an elbow joint; the elbow joint is communicated with a numerical control machine tool water tank through an exhaust pipe; the electromagnetic valve is in electric signal communication with the numerical control machine tool electrical control unit; by introducing the three-way connector structure, under the control of the electromagnetic valve, automatic exhaust is achieved, manual deflation is not needed, and the problem that water cannot be pumped due to the fact that a gear pump does not work for a long time and enters air is solved. 本实用新型涉及一种用于数控机床的自动
