[0034] Optionally, the measuring gauge 11 is provided with several measuring slots 11 at intervals. Every two measuring slots 11 form a group to form a first calibration piece, so that the measuring gauge 1 has several first calibration pieces of different lengths for measuring the outer diameter of different types of gear rings, thereby improving the versatility of the device. Specifically, the device can realize multi-size measurement from 1200mm to 4000mm. The reference surfaces on both sides of each measuring slot 11 are both measuring working surfaces, and the calibration size is selected according to the different sizes of the product.

[0035] Optionally, the measuring gauge 1 is provided with several size markings, with a set of size markings corresponding to each first calibration piece.

Specifically, when the gauge is installed on one of the first positioning rods 32, the first support block 31 supports the upper surface of the measuring gauge 1, and the other first positioning rod 32 is fixed as the calibration starting point and abuts against the side of the measuring groove 11. The first positioning rod 32 with the gauge installed is moved so that it abuts against the side of the other corresponding measuring groove 11, and the gauge is zeroed. At this time, the calibration of the first measuring rod 2 is completed. Then, the entire device is moved to the gear ring to be measured. The first support block 31 supports the upper surface of the gear ring, and the other first positioning rod 32 abuts against the outer side of the gear ring. The first positioning rod 32 with the gauge installed is moved so that it abuts against the outer side of the gear ring.
