[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2The present invention provides an embodiment of a simple indexing universal rotary table, comprising a connecting frame 1 and a connecting shell 18. An indexing rotary assembly 2 is disposed within the connecting frame 1. A rotating column 3 is rotatably connected to the side of the connecting frame 1. A support assembly 4 is mounted on the side of the rotating column 3. A base plate 5 is disposed on the top of the support assembly 4. A work surface 6 is rotatably connected to the top of the base plate 5. A drive assembly 7 is mounted within the base plate 5. The indexing rotary assembly 2 includes a connecting column 8, which is fixedly connected to the interior of the connecting frame 1 and is connected to the indexing rotary assembly 2 using the connecting frame 1. The interior of the connecting column 8 is rotatably connected to a bevel gear 10. The side of the rotating column 3 is fixedly connected to a bevel gear 2 10. Bevel gear 10 meshes with bevel gear 10. A sliding column 11 is slidably connected to the outer side of bevel gear 19. When bevel gear 19 rotates, bevel gear 2 10 rotates with it. A motor 12 is fixedly connected to the side of the connecting shell 18. Bevel gear 19 is fixedly connected to the output end of the motor 12. The motor 12 drives the bevel gear 19 to rotate. The outer side of bevel gear 19 is fixedly connected with slider 13, the outer side of sliding column 11 is fixedly connected with slider 2 14, and the interior of connecting column 8 and sliding column 11 is provided with sliding groove 26, slider 13 and slider 2 14 are respectively slidably connected inside the two sliding grooves 26, and the bottom of sliding column 11 is fixedly connected with sliding rod 15, and sliding rod 15 is used to move sliding column 11 backward so that slider 13 enters the sliding groove 26 of sliding column 11. At this time, when motor 12 rotates bevel gear 19, sliding column 11 will rotate in the same direction with connecting column 8, connecting frame 1, rotating column 3 and bevel gear 2 10. Bevel gear 19 and bevel gear 2 10 are relatively stationary, so that rotating column 3 and bevel gear 19 have the same rotation direction, and rotate base plate 5 and work table 6 according to a certain indexing angle. When the sliding rod 15 controls the sliding column 11 to move forward, so that the slider 13 disengages from the sliding groove 26 of the sliding column 11, the connecting column 8 and the connecting frame 1 will not rotate together with the bevel gear 1 9. At this time, the bevel gear 1 9 rotates the bevel gear 2 10, so that the rotating column 3 and the bevel gear 2 10 have the same rotation direction, thereby moving the base plate 5 and the work table 6 to different positions.

[0033] Reference Figure 1-Figure 3The support assembly 4 includes a spherical support frame 16, which is fixedly connected to the side of the rotating column 3. The spherical support frame 16 is rotatably connected to the inside of the connecting shell 18. The top of the spherical support frame 16 is fixedly connected to the bottom of the base plate 5. The spherical support frame 16 rotates together with the rotating column 3 and the base plate 5 on the top. The inside of the spherical support frame 16 is fixedly connected to a connecting plate 17, one end of the connecting plate 17 is fixedly connected to the outside of the rotating column 3, and the bottom of the connecting shell 18 is slidably connected to a bottom shell 19. The connecting shell 18 moves up and down inside the bottom shell 19. The inside of the bottom shell 19 is fixedly connected to a hydraulic cylinder 20, and the bottom of the connecting shell 18 is fixedly connected to the output end of the hydraulic cylinder 20. The hydraulic cylinder 20 controls the lifting and lowering of the connecting shell 18, thereby driving the base plate 5 and the work table 6 to move to different positions.

[0034] Reference Figure 1 、 Figure 3 and Figure 4 The drive assembly 7 includes a rotary shaft 21, which is rotatably connected to the inside of the base plate 5. The rotary shaft 21 is fixedly connected to the bottom of the work surface 6. The work surface 6 rotates together with the rotary shaft 21. A worm gear 22 is fixedly connected to the side of the rotary shaft 21, and a worm 23 is rotatably connected to the inside of the base plate 5. The worm 23 and the worm gear 22 are engaged with each other. The worm gear 22 and the rotary shaft 21 are rotated by the worm 23 to control the rotation of the work surface 6. A handle 24 is fixedly connected to one end of the worm gear 23. The handle 24 is used to assist in rotating the worm gear 23. A slot 25 is provided inside the connecting shell 18, and the sliding rod 15 is slidably connected inside the slot 25. By providing the slot 25, space is provided for the sliding rod 15 to move when the spherical support frame 16 changes its orientation.

[0035] Working principle: When the work surface 6 needs to be rotated at an indexing angle, the control sliding rod 15 moves the sliding column 11 forward, so that the slider 13 is separated from the slide groove 26 of the sliding column 11, and the motor 12 is started to rotate the bevel gear 1 9, and the connecting column 8, the connecting frame 1, the rotating column 3 and the bevel gear 2 10 are rotated together through the sliding column 11. The bevel gear 1 9 and the bevel gear 2 10 are relatively stationary, and the spherical support frame 16 rotates in the same direction as the bevel gear 1 9, which can control the work surface 6 to rotate at an indexing angle. When the work surface 6 needs to be moved, When the slider 13 is pulled out of the sliding rod 15, the slider 13 slides into the sliding groove 26 of the sliding rod 15. At this time, the motor 12 is started to rotate the bevel gear 19. The connecting column 8, the connecting frame 1 and the rotating column 3 do not rotate with the bevel gear 19. The bevel gear 19 rotates the bevel gear 2 10, so that the rotating column 3 and the spherical support frame 16 have the same rotation direction as the bevel gear 2 10, thereby changing the orientation of the work table 6. The hydraulic cylinder 20 is used to control the connecting shell 18 to slide in the bottom shell 19, adjust the height of the work table 6, and realize the multi-directional movement of the work table 6.
