[0008] A further improvement is that: a guide groove is provided inside the turntable, and a guide block is provided inside the guide groove, with the top end of the guide block connected to the bottom end of the positioning plate.

[0009] A further improvement is that the cross-section of the guide groove is larger than the cross-section of the guide block, and the guide groove and the guide block form a sliding structure.

[0018] To deepen the understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatic rotary positioning and processing platform system for heavy workpieces, including a base 1, a rotating mechanism is provided inside the base 1, a turntable 2 is installed at the top of the base 1, a clamping mechanism is provided inside the turntable 2, and a positioning plate 3 is installed above the turntable 2.

[0020] The clamping mechanism includes a first servo motor 4, threaded rods 5, threaded sleeves 6, a first bevel gear 7, a second bevel gear 8, a third bevel gear 9, a connecting rod 10, and a limiting structure. The first servo motor 4 is mounted on the front end of the turntable 2. Four threaded rods 5 are vertically mounted inside the first servo motor 4, and threaded sleeves 6 are mounted on the outer sides of each of the four threaded rods 5. The top end of each threaded sleeve 6 is connected to the bottom end of the positioning plate 3. A first bevel gear 7 is mounted on one end of one threaded rod 5. A second bevel gear 8 meshes with one side of the first bevel gear 7. One end of the second bevel gear 8 is connected to one end of one threaded rod 5. A connecting rod 10 is mounted on the other end of the second bevel gear 8. One end of the connecting rod 10 is connected to one end of another threaded rod 5. A third bevel gear 9 meshes with the other side of the second bevel gear 8. One end of the third bevel gear 9... Connected to one end of another threaded rod 5, in use, the heavy workpiece is hoisted above the turntable 2, and then the first servo motor 4 is started to drive the threaded rod 5 to rotate. Thus, the threaded rod 5 drives the first bevel gear 7 to rotate. Since the second bevel gear 8 meshes with the first bevel gear 7 and the third bevel gear 9 respectively, the transmission between the first bevel gear 7, the second bevel gear 8, the third bevel gear 9 and the connecting rod 10 drives the four threaded rods 5 to rotate. Then, under the limitation of the limiting groove 11 and the limiting block 12, the threaded rod 5 drives the threaded sleeve 6 to rotate. Then, under the guidance of the guide groove 13 and the guide block 14, the threaded sleeve 6 drives the positioning plate 3 to move. The four positioning plates 3 are used to position the heavy workpiece, making the heavy workpiece more stable during processing and less prone to displacement, thereby greatly improving the practicality of the processing platform in use.

[0021] The limiting structure includes a limiting groove 11 and a limiting block 12. The limiting groove 11 is opened inside the turntable 2, and the limiting block 12 is provided inside the limiting groove 11. One end of the limiting block 12 is connected to one side of the threaded sleeve 6. In use, the mutual cooperation between the limiting groove 11 and the limiting block 12 can limit the movement of the threaded sleeve 6, making the threaded sleeve 6 more stable when moving.

[0022] The turntable 2 has a guide groove 13 inside, and a guide block 14 is provided inside the guide groove 13. The top end of the guide block 14 is connected to the bottom end of the positioning plate 3. The cross-section of the guide groove 13 is larger than the cross-section of the guide block 14. The guide groove 13 and the guide block 14 form a sliding structure. In use, the cooperation between the guide groove 13 and the guide block 14 can guide the positioning plate 3 when it moves, making the positioning plate 3 more stable when it moves.

[0023] The rotating mechanism includes a second servo motor 15, a worm gear 16, a worm wheel 17, a fixed groove 18, and a movable block 19. The second servo motor 15 is mounted on the front end of the base 1. The worm gear 16 is mounted inside the base 1. The output end of the second servo motor 15 is connected to one end of the worm gear 16. The worm wheel 17 meshes with one side of the worm gear 16. The top end of the worm wheel 17 is connected to the bottom end of the turntable 2. The fixed groove 18 is opened inside the base 1. The movable block 19 is disposed inside the fixed groove 18. The top end of the movable block 19 is connected to the turntable 2. The bottom end of disk 2 is connected. When in use, the second servo motor 15 is started to drive the worm gear 16 to rotate. Since the worm gear 16 and the worm wheel 17 are meshed with each other, the worm wheel 17 is driven to rotate. Under the limit of the fixed groove 18 and the movable block 19, the worm wheel 17 drives the turntable 2 to rotate, thereby driving the heavy workpiece to rotate. A hydrostatic bearing is set above the worm wheel 17 to bear the axial load, which significantly improves the load-bearing capacity and makes the heavy workpiece more stable when rotating, thus greatly improving the stability of the processing platform during use.

[0024] Multiple movable blocks 19 are provided inside the fixed groove 18. The multiple movable blocks 19 are distributed at equal intervals inside the fixed groove 18. In use, the cooperation between the fixed groove 18 and the movable blocks 19 can limit the rotation of the turntable 2, making the turntable 2 more stable when rotating. The design of four movable blocks 19 can support heavy workpieces, share radial force, and significantly improve load-bearing capacity.

[0025] Working principle: The operator first hoists the heavy workpiece onto the turntable 2, then starts the first servo motor 4 to drive the threaded rod 5 to rotate. The threaded rod 5 then drives the first bevel gear 7 to rotate. Since the second bevel gear 8 meshes with the first bevel gear 7 and the third bevel gear 9 respectively, the transmission between the first bevel gear 7, the second bevel gear 8, the third bevel gear 9, and the connecting rod 10 drives the four threaded rods 5 to rotate. Then, under the limitation of the limiting groove 11 and the limiting block 12, the threaded rods 5 drive the threaded sleeve 6 to rotate. Finally, under the guidance of the guide groove 13 and the guide block 14, the threaded sleeve... The 6th motor moves the positioning plate 3, using four positioning plates 3 to position the heavy workpiece. When the turntable 2 needs to be rotated, the second servo motor 15 is started to drive the worm gear 16 to rotate. Since the worm gear 16 and the worm wheel 17 mesh with each other, the worm wheel 17 is driven to rotate. Then, under the limit of the fixed groove 18 and the movable block 19, the worm wheel 17 drives the turntable 2 to rotate, thereby driving the heavy workpiece to rotate. A hydrostatic bearing is set above the worm wheel 17 to bear the axial load. The design of the four movable blocks 19 can support the heavy workpiece, share the radial force, and significantly improve the load-bearing capacity.
