[0016] This positioning tooling can be adjusted for bearings of different sizes to position and fix bearings of different sizes. At the same time, this positioning tooling can take into account the positioning and fixing of the inner arc surface and the outer arc surface of the bearing, thereby effectively improving the applicability and performance of the tooling. And the structure of this positioning tooling is designed simply, and the use and adjustment operations are convenient and fast. The positioning and fixing are stable and reliable, and its performance can meet the use requirements of bearing processing.

[0017] The three adjusting components 6 all include T-shaped rotating plates 7. The three T-shaped rotating plates 7 are rotationally connected at equal intervals in a ring shape on the surface of the cylindrical device base 1. The upper parts of the three T-shaped rotating plates 7 are rotationally connected with first linkage rods 8. One ends of the three first linkage rods 8 are respectively rotationally connected with one ends of the three square moving rods 4. The lower parts of the three T-shaped rotating plates 7 are fixedly connected with transmission rods 9, so as to effectively move and adjust the square moving rods 4 and the convex blocks 5;

[0018] A drive groove 10 is provided in the middle of the cylindrical device seat 1. Three vertical through grooves 11 communicating with the drive groove 10 are equidistantly arranged in a ring on the surface of the cylindrical device seat 1. In the middle of the bottom of the drive groove 10, an n-shaped frame 12 is fixedly installed. A slide bar 13 is fixedly installed between the top of the n-shaped frame 12 and the top of the drive groove 10. A lifting slide sleeve 14 is movably sleeved on the surface of the slide bar 13. Three second linkage rods 15 are rotatably connected to the surface of the lifting slide sleeve 14 at equal intervals in a ring. The three drive rods 9 respectively extend into the interior of the drive groove 10 through the three vertical through grooves 11, and one ends of the three drive rods 9 are respectively rotatably connected to one ends of the three second linkage rods 15, so as to be able to adjust the three shaped moving rods 4 and the three convex blocks 5 synchronously;
