[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a robot joint flexible steering connection assembly, including a support plate 1, a fixing post 2 fixedly connected to the outer wall of the support plate 1, a fixing block 3 fixedly connected to the outer wall of the fixing post 2, a connecting shaft 4 rotatably connected inside the fixing block 3, a rotating shaft 5 fixedly connected inside the connecting shaft 4, a connecting block 6 rotatably connected to the outer wall of the rotating shaft 5, a fixing post 7 fixedly connected to the outer wall of the connecting block 6, a fixing plate 8 fixedly connected to the outer wall of the fixing post 7, and a support assembly provided on the outer wall of the fixing plate 8.

[0024] Specifically, support plate 1 fixes fixed column 2, fixed column 2 fixes fixed block 3, and support plate 1 is fixedly installed at the joint of the robot body. When the robot's drive device drives fixed plate 8, fixed plate 8 fixes fixed column 7, fixed column 7 fixes connecting block 6. By rotating the connecting block 6 on the outer wall of rotating shaft 5, fixed plate 8 can move flexibly in the horizontal direction. By rotating the connecting shaft 4 inside fixed block 3, fixed plate 8 can move flexibly in the vertical direction, thus achieving flexible movement of fixed plate 8 in both the horizontal and vertical directions. Fixed plate 8 is fixedly connected to the end of the robot's arm, thus providing support for the robot to perform complex movements.

[0025] Reference Figure 3 The support assembly includes a bracket 9, the outer wall of which is fixedly connected to the outer wall of the fixing plate 8, and a fixing cylinder 10 is fixedly connected to the outer wall of the bracket 9.

[0026] Specifically, the bracket 9 fixes the fixing plate 8 and the fixing cylinder 10. The bracket 9 and the fixing cylinder 10 are used to support the structure at the tail end of the joint.

[0027] Reference Figure 3 and Figure 4 A motor 11 is fixedly connected inside the bracket 9. A gear 12 is fixedly installed at the output end of the motor 11. The outer wall of the gear 12 is rotatably connected inside the fixed cylinder 10. A gear 13 is meshed with the tooth end of the gear 12. A fixed shaft 15 is rotatably connected inside the gear 13. The outer wall of the fixed shaft 15 is fixedly connected inside the fixed cylinder 10. A connecting rod 14 is fixedly connected to the outer wall of the gear 13. The connecting rod 14 is rotatably connected to the outer wall of the fixed shaft 15. A limit plate 16 is fixedly connected to the outer wall of the fixed shaft 15. A limit post 17 is fixedly connected inside the limit plate 16. A rotating rod 18 is rotatably connected to the outer wall of the limit post 17. A rotating shaft 19 is fixedly connected inside the rotating rod 18. A rotating plate 20 is rotatably connected to the outer wall of the rotating shaft 19. A connecting post 21 is fixedly connected inside the rotating plate 20. The outer wall of the connecting post 21 is rotatably connected to the inside of the connecting rod 14. A connecting plate 22 is fixedly connected to the upper surface of the connecting post 21.

[0028] Specifically, bracket 9 serves to fix motor 11. Starting motor 11 drives gear 12 to rotate, which in turn drives gear 2 13 to rotate on the outer wall of fixed shaft 15. The rotation of gear 2 13 reduces speed. Fixed shaft 15 and fixed cylinder 10 provide fixation. Fixed shaft 15 supports and limits gear 2 13. Gear 2 13 drives connecting rod 14 to rotate, which in turn drives connecting column 21 to rotate inside the connecting rod 14. Connecting column 21 drives rotating plate 20 to rotate on the outer wall of rotating shaft 19. Rotating shaft 19 drives rotating rod 18 to rotate on the outer wall of limiting column 17. Limiting column 17 fixes limiting plate 16, which in turn fixes fixed shaft 15. Rotating rod 18 provides stable connection during rotation, thus achieving stable rotation of the structure.

[0029] Working principle: When this connecting component is needed, the support plate 1 is first installed at the robot's joint. By rotating the connecting block 6 on the outer wall of the rotating shaft 5, the component can rotate horizontally. By rotating the connecting shaft 4 inside the fixed block 3, the component can rotate vertically. Furthermore, the rotation of the connecting block 6 and the connecting shaft 4 allows the fixed column 7 and the fixed plate 8 to rotate horizontally and vertically, thus enabling horizontal and vertical rotation at the robot joint. This improves the flexibility of the joint, allowing for multi-directional rotation and enhancing the robot's practicality. The motor 11 drives the gear 12 to rotate... While gear 12 rotates, it drives gear 23 to rotate. Gear 23 drives connecting rod 14 to rotate on the outer wall of fixed shaft 15. While connecting rod 14 rotates, connecting column 21 rotates inside connecting rod 14. At the same time, it drives rotating plate 20 to rotate on the outer wall of rotating shaft 19, which in turn drives rotating shaft 19 to rotate on the outer wall of limiting column 17, which in turn drives connecting plate 22 to rotate. This achieves the effect of automatically rotating the tail of the joint, improving the stability and accuracy of robot movement. This connecting component can not only drive the robot to rotate flexibly in multiple directions to achieve complex movements, but also drive one end of the robot joint to move stably and accurately, improving the overall stability of the robot structure.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
