Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment 1

[0027] Please refer to Figure 1 、 Figure 2 and Figure 4, the utility model provides a technical solution: including a base 1, a rotating shaft one 11 and a rotating shaft two 12 are rotatably connected inside the base 1, and a servo motor 13 is fixedly installed inside the base 1. A large gear 15 and a medium gear 16 are respectively fixedly connected to the outer walls of the rotating shaft one 11 and the rotating shaft two 12. The output end of the servo motor 13 is fixedly installed with a rotating shaft three 14, and a small gear 17 is fixedly connected to the outer wall of the rotating shaft three 14. The small gear 17 is meshed with the medium gear 16, and the medium gear 16 is meshed with the large gear 15. The upper end of the rotating shaft one 11 is fixedly installed with a turntable 2. Both sides of the top of the turntable 2 are fixedly connected with vertical rods 3. And a three-jaw chuck 4 is arranged above the turntable 2. Connecting shafts 5 are symmetrically and fixedly installed on both sides of the three-jaw chuck 4. The connecting shafts 5 penetrate through the three-jaw chuck 4. An electric cylinder 8 is fixedly installed on one side of a vertical rod 3. One end of a connecting shaft 5 is fixedly connected with a rotating gear 21. The output end of the electric cylinder 8 is fixedly installed with a toothed groove plate 20. The toothed groove plate 20 is meshed with the rotating gear 21;

[0028] In this technical solution, the rotation of the rotating shaft three 14 is driven by the servo motor 13. Since the meshing connection between the small gear 17 and the medium gear 16 can drive the rotating shaft two 12 to rotate at a reduced speed, and since the meshing connection between the medium gear 16 and the large gear 15 can drive the rotating shaft one 11 to rotate at a further reduced speed, the turntable 2 and the three-jaw chuck 4 can be driven to rotate at a reduced speed on the horizontal plane, and the rotation accuracy is high. And the movement of the toothed groove plate 20 is driven by the electric cylinder 8. Since the meshing connection between the toothed groove plate 20 and the rotating gear 21 can drive the connecting shaft 5 to rotate, the three-jaw chuck 4 can be driven to rotate on the vertical plane, and the workpiece fixed by the three-jaw chuck 4 can be adjusted in three-dimensional angles, so as to better process each surface of the workpiece.

[0029] In some technical solutions, such as Figure 1 and Figure 3 shown, three jaws 6 are arranged on the three-jaw chuck 4. A set of heightening components 7 are arranged on the top of each jaw 6. Each set of heightening components 7 includes three heightening blocks 71 and three bolts 72. A first threaded hole 18 is opened on the top of the jaw 6. A second threaded hole 19 is opened on the heightening block 71. The first threaded hole 18, the second threaded hole 19 and the bolt 72 are all adapted to each other.

[0030] During use, by placing the heightening block 71 on the jaw 6 and screwing the bolt 72 into the first threaded hole 18 and the second threaded hole 19, the installation between the jaw 6 and a heightening block 71 can be completed. Similarly, the heightening blocks 71 can be stacked, and the bolt 72 is screwed into the second threaded hole 19, and the heightening blocks 71 can be installed, realizing the heightening effect of the three-jaw chuck 4, so as to be applicable to workpieces of different thicknesses.

[0031] In some technical solutions, such as Figure 1 and Figure 4 shown, the connecting shaft 5 and the vertical rod 3 are connected by a bearing.

[0032] During use, the stability of the rotation of the connecting shaft 5 is increased.

[0033] In some technical solutions, such as Figure 1 As shown, legs 9 are fixedly installed at the four corners of the bottom of the base 1, and foot pads 10 are fixedly connected to the lower ends of the legs 9.

[0034] During use, the stability of the placement of this indexing rotary table is increased.

[0035] In some technical solutions, such as Figure 1 and Figure 3 As shown, the ends of the chuck 6 and the heightening block 71 are both in arc shapes.

[0036] During use, the stability of the chuck 6 and the heightening block 71 for fixing the workpiece is increased.

[0037] In some technical solutions, such as Figure 1 and Figure 2 As shown, the servo motor 13 and the electric cylinder 8 are both externally connected to a power source.

[0038] During use, electrical energy is provided for the operation of the servo motor 13 and the electric cylinder 8. Embodiment 2

[0039] Working principle: During the use process, place the heightening block 71 on the chuck 6, screw the bolt 72 into the internal thread holes 18 and 19, and the installation between the chuck 6 and one heightening block 71 can be completed. Similarly, the heightening blocks 71 can be stacked, and the bolt 72 is screwed into the thread hole 19 to install each heightening block 71, achieving the heightening effect of the three-jaw chuck 4. Then, fix the workpiece on the three-jaw chuck 4. The servo motor 13 drives the rotation shaft 14 to rotate. Since the meshing connection between the small gear 17 and the middle gear 16 can drive the rotation shaft 12 to rotate at a reduced speed, and since the meshing connection between the middle gear 16 and the large gear 15 can drive the rotation shaft 11 to further rotate at a reduced speed, the turntable 2 and the three-jaw chuck 4 can be driven to rotate at a reduced speed on the horizontal plane, and the rotation accuracy is high. Moreover, the electric cylinder 8 drives the toothed groove plate 20 to move. Since the meshing connection between the toothed groove plate 20 and the rotating gear 21 can drive the connecting shaft 5 to rotate, the three-jaw chuck 4 can be driven to rotate in the vertical plane, and the workpiece fixed by the three-jaw chuck 4 can be adjusted in three-dimensional angles to better process each surface of the workpiece.
