[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3A multi-directional adjustable tower welding robot gripper includes a second support platform 17. A groove is formed on the top of the second support platform 17, and a bidirectional lead screw 22 is rotatably mounted within the groove. Two sets of internally threaded sliders 23 are evenly screwed onto the outer wall of the bidirectional lead screw 22. A hydraulic rod 21 is fixedly mounted on the top of the internally threaded sliders 23. Two sets of gripping plates 18 are evenly placed on the top of the second support platform 17. A first insertion hole is formed at the bottom of the gripping plate 18, and the telescopic end of the hydraulic rod 21 is inserted into the first insertion hole. Two sets of second insertion holes are evenly formed at the bottom of the gripping plate 18. A guide post 24 is slidably disposed within the hole, and a guide sleeve 25 is fitted around the outer ring of the guide post 24. Two sets of clearance grooves are evenly distributed through the top of the second support platform 17, and guide grooves are formed within these clearance grooves. The guide sleeve 25 and guide post 24 are slidably disposed within the clearance grooves. An anti-slip sleeve 26 is fixedly disposed within the guide sleeve 25, and the anti-slip sleeve 26 is fitted around the outer ring of the guide post 24. The friction between the guide post 24 and the anti-slip sleeve 26 allows the guide post 24 to remain stable within the guide sleeve 25. A [missing information - likely a device or structure] is fixedly disposed on the rear side of the second support platform 17. The third servo motor 2, with its output end passing through the rear side of the second support platform 17 and connected to the bidirectional lead screw 22, drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 then drives two sets of internally threaded sliders 23 to move inward synchronously. This, in turn, drives the hydraulic rod 21 to move synchronously, which in turn drives two sets of gripping plates 18 to move inward synchronously. The tower component is then placed between the two sets of gripping plates 18, which grip and hold it by moving inward. As the gripping plates 18 move... When in motion, the guide sleeve 25 moves via the guide post 24, thereby assisting the gripper plate 18 in moving stably. A threaded hole is provided through the right side of the gripper plate 18, which is connected to the first insertion hole and the second insertion hole. Through holes are provided on the outer side of the telescopic end of the hydraulic rod 21 and the outer side of the guide sleeve 25. Bolts 19 pass through the through holes and are screwed into the threaded hole of the gripper plate 18. The bolts 19 also pass through the through holes of the hydraulic rod 21 and the guide post 24, thereby fixing the hydraulic rod 21 and the guide post 24 to the gripper plate 18.

[0020] A concave frame 14 is placed below the second support platform 17. A first support platform 16 is rotatably mounted inside the concave frame 14 via a rotating shaft. The second support platform 17 is fixedly mounted on top of the first support platform 16. A second servo motor 15 is fixedly mounted on the front side of the concave frame 14. The output end of the second servo motor 15 passes through the front side of the concave frame 14 and connects to the first support platform 16. The second servo motor 15 drives the first support platform 16 to tilt left and right, thereby tilting the second support platform 17, which in turn tilts the tower component fixed to the top of the second support platform 17. A support plate is rotatably mounted at the bottom of the concave frame 14. 12. A first servo motor 13 is fixedly installed at the bottom of the support plate 12. The output end of the first servo motor 13 passes through the top of the support plate 12 and is connected to the concave frame 14. The first servo motor 13 drives the concave frame 14 to rotate, and the concave frame 14 drives the second support platform 17 to rotate, thereby driving the iron tower component fixed on the top of the second support platform 17 to rotate. Support columns 11 are evenly fixedly installed at the bottom of the support plate 12. A flange 1 is fixedly installed at the bottom of the support column 11. The flange 1 is connected to the end of the welding robot by flange connection. With this device installed, the flange 1 is located below the first servo motor 13.

[0021] Working principle: Bolt 19 is screwed into the threaded hole of the gripper plate 18 and passes through the through hole of the hydraulic rod 21 and the guide column 24, thereby fixing the hydraulic rod 21 and the guide column 24 to the gripper plate 18. The device is installed by connecting the flange 1 to the end of the welding robot.

[0022] The third servo motor 2 drives the bidirectional lead screw 22 to rotate, which in turn drives two sets of internal threaded sliders 23 to move inward synchronously. This, in turn, drives the hydraulic rod 21 to move inward synchronously, which in turn drives the two sets of gripping plates 18 to move inward synchronously. At this time, the tower component is placed between the two sets of gripping plates 18, which grip and hold it by moving inward. When the gripping plates 18 move, they drive the guide sleeve 25 to move through the guide column 24, which assists the gripping plates 18 to move stably. After the gripping plates 18 have gripped and held the tower component, the hydraulic rod 21 can drive the gripping plates 18 to move up and down, which in turn drives the tower component to move up and down. When the gripping plates 18 move up and down, they drive the guide column 24 to move up and down within the guide sleeve 25, which assists the gripping plates 18 to move up and down stably.

[0023] The second servo motor 15 drives the first support platform 16 to tilt left and right, thereby tilting the second support platform 17 of the first support platform 16, which in turn drives the iron tower component fixed on the top of the second support platform 17 to tilt. The first servo motor 13 drives the concave frame 14 to rotate, which in turn drives the second support platform 17 to rotate, thereby driving the iron tower component fixed on the top of the second support platform 17 to rotate.

[0024] After unscrewing bolt 19, the gripper plate 18 can be moved upward to separate from the hydraulic rod 21 and guide post 24. Then, gripper plates 18 of other shapes and sizes can be reconnected to the guide post 24 and hydraulic rod 21 and fixed with bolt 19. This allows for quick disassembly and replacement of the gripper plate 18. When connecting the gripper plate 18 to the guide post 24, the friction between the guide post 24 and the anti-slip sleeve 26 can stabilize the guide post 24 within the guide sleeve 25, making it easier for the gripper plate 18 to connect with the guide post 24 and thus improving the ease of installation of the gripper plate 18.

[0025] It is worth noting that a set of cable routing ports are provided on both the front and rear sides of the slide groove of the second support platform 17, so that the external infusion pipeline can pass through the cable routing ports and connect to the hydraulic rod 21. The hydraulic rod 21 can be an STM mini air-hydraulic booster cylinder. The outer ring of the infusion pipeline of the hydraulic rod 21 and the power supply lines of the third servo motor 2, the second servo motor 15 and the first servo motor 13 can be fitted with a universal metal corrugated pipe to prevent the various lines from tangling and interfering with each other.
