Numerical control spring grinder capable of adaptively adjusting grinding wheel gap

The utility model provides a numerical control spring grinder capable of adaptively adjusting a grinding wheel gap, which comprises a detection unit arranged corresponding to a grinding wheel of the spring grinder, and the detection unit comprises an upper detection device corresponding to an upper grinding wheel surface and a lower detection device corresponding to a lower grinding wheel surface. And each detection device comprises a plurality of infrared distance meters corresponding to different grinding wheel surface positions. The detected distance between the upper grinding wheel face and the lower grinding wheel face is fed back to the control system in real time, the control system controls the driving mechanism to adjust the gap between the upper grinding wheel face and the lower grinding wheel face in real time, and the gap between the upper grinding wheel face and the lower grinding wheel face is always kept to be a set value. The gap between the upper grinding wheel surface and the lower grinding
