Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the present utility model can be more clearly defined.

Please refer to FIG. 1 to FIG. 3, the embodiments of the present utility model include:

A tooling for measuring the size of an annular cutting iron core, the tooling for measuring the size of an annular cutting iron core comprises a measuring block 1, a screw rod 2 and an inner diameter measuring body 3, the upper end of the measuring block 1 is provided with a rectangular groove 10. The depth of the rectangular groove 10 is consistent with the maximum height of the annular cutting iron core. One end of the measuring block 1 is provided with a notch 11, and the distance between the notch 11 and the bottom surface of the rectangular groove 10 is the minimum value of the height of the annular cutting iron core. The length and width of the groove 10 are consistent, which is the maximum outer diameter of the annular cutting iron core. The measuring block 1 is also provided with a triple helix 2.
