[0037] In the above scheme, when the inner diameter of the annular titanium forging 2 is polished, the annular titanium forging 2 is limited by the set clamping assembly 5, and the lifting part is controlled to start so that the polishing part 7 slides back and forth up and down along the height direction of the annular titanium forging 2, and then the polishing part 7 is adjusted so that the polishing part 7 can adapt to the inner diameters of annular titanium forgings 2 of different sizes. Compared with the prior art, there is no need to replace the polishing column of the corresponding diameter according to the inner diameter of the annular titanium forging 2 for polishing, which improves the polishing efficiency and also reduces the labor intensity of the staff.

[0038] In some possible implementations, see Figure 5As shown, the grinding part 7 includes a connecting plate 71, and the connecting plate 71 has a vertical section and a horizontal section. The upper surface of the horizontal section near one end of the vertical section is provided with a long groove along its length direction. A rotatable rotating rod 74 is arranged in the long groove along its length direction. The rotating rod 74 is driven by a first driving motor 72. Both ends of the rotating rod 74 are provided with threads along its length direction. The thread directions of the two threads are arranged in opposite directions.

The support plate 52 is provided with an avoidance opening that matches the claw 51. The claw 51 at least partially extends out of the avoidance opening, and the multiple sets of second connecting rods 58 are arranged along the height direction of the central column 54.

[0047] In the above scheme, the second connecting rod 58 is provided to hinge the side of the claw 51 close to the center column 54 and the peripheral wall of the center column 54, so that the claw 51 is always in a vertical state during the movement of the claw 51, thereby facilitating the clamping of the annular titanium forging 2 and improving the clamping stability.
