The utility model discloses a calibrating device for calibrating an aperture gauge in the technical field of aperture calibration, which comprises a calibrating device fixing base and a calibrating device main body conical rod, and the calibrating device main body conical rod is inserted and assembled in the middle of the top of the calibrating device fixing base. The gauge is a simple tool for controlling various sizes (such as aperture, space size and the like) of products in industrial production enterprises, such as automobile parts, so as to replace professional measuring tools such as smooth plug gauges, thread plug gauges, external diameter caliper gauges and the like, and is mainly used for improving the production efficiency and the control quality. The length is adjusted through rotation of the knurled screw of the calibrating device, and the top and the bottom are clamped in the aperture, so that the size of the aperture can be obtained through the dial indicator, and the aperture can be directly p
