[0002] As a key component of ships, offshore platforms, and other maritime facilities, the production of anchor chains involves multiple stages, including material selection, process design, and quality control, directly affecting the safety, reliability, and service life of the product. Anchor chains are made of high-strength, high-toughness special steel, using CNC flame cutting or laser cutting, and are heated to 900-1100℃ by medium-frequency induction heating. They are formed in one step using a three-roll bending machine to reduce the cold work hardening effect and retain the material's ductility. The end face is heated to a molten state by instantaneous high current heating, and upsetting force is applied to complete the welding. During the welding process of anchor chains, positioning devices are required to achieve efficient positioning and stable processing of the anchor chain welding stage.

[0003] In the prior art, a welding positioning device for anchor chain production involves transporting the anchor chain to the inside of the welding device by machine and manually adjusting the position of the anchor chain. However, the accuracy of the position adjustment is low when the worker manually adjusts it, resulting in long welding processing time, low efficiency, and high risk for workers to stand at the edge of the welding table.

[0004] Therefore, this utility model proposes a welding positioning device for anchor chain production to solve the above problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: an anchor chain production welding positioning device, the anchor chain production welding positioning device includes: a base 1, a fixed lifting frame 2 and a movable lifting frame 3 installed on the top of the base 1, a clamping block 4 installed on the inner side wall of the fixed lifting frame 2 and the movable lifting frame 3, a transverse groove 5 opened on the side wall of the clamping block 4, a first threaded rod 6 installed inside the transverse groove 5, a positioning component 7 installed on the outer surface of the first threaded rod 6, the positioning component 7 includes a movable plate 8, a long groove 9 opened inside the movable plate 8, a moving plate 10 installed inside the long groove 9, the moving plate 10 is an L-shaped long plate, a positioning plate 13 is installed at the bottom of the outer end of the moving plate 10, a toothed plate 14 is installed on the top of the positioning plate 13, the toothed plate 14 penetrates the interior of the moving plate 10;

[0023] In use, after the fixed lifting frame 2 and the movable lifting frame 3 drive the clamping block 4 to move away from each other and open, the first threaded rod 6 is rotated by the drive system, which facilitates the horizontal movement of the movable plate 8 of the positioning component 7 inside the transverse groove 5. The movable plate 10 then moves the positioning plate 13 to the inside of the clamping block 4. After the positioning plate 13 is rotated by the toothed plate 14, the anchor chain can be moved to the center position inside the clamping block 4 by the inclination of the positioning plate 13. After the anchor chain is clamped by the clamping block 4, it is easy to weld quickly and accurately, improving the welding speed and accuracy.

[0024] Example 2: Based on Example 1, a structure is provided to drive the moving plate 10 to move and position. A drive motor 11 is installed on the side wall of the long groove 9. A second threaded rod 12 is installed at the output end of the drive motor 11. The second threaded rod 12 is located inside the long groove 9 and penetrates the side wall of the moving plate 10.

[0025] In use, the drive motor 11 provides driving force to the second threaded rod 12, causing the second threaded rod 12 to rotate, thereby facilitating the movement of the moving plate 10 inside the long groove 9, and making it convenient to send the positioning plate 13 at the outer end of the moving plate 10 into the clamping block 4 for use.

[0026] Example 3: Based on Example 2, a structure for fixing the positioning plate 13 is provided. The moving plate 10 has an opening groove 15 inside. A spring 16 is installed inside the opening groove 15. A stop block 17 is installed at the outer end of the spring 16. The stop block 17 is located inside the opening groove 15 and moves between adjacent teeth of the toothed plate 14. A lifting block 18 is installed inside the opening groove 15. An inclined block 19 is installed on the top of the lifting block 18. The side wall of the inclined block 19 is in contact with the side wall of the stop block 17.

[0027] In use, the spring 16 provides an inward pulling force to the stop block 17. When the lifting block 18 moves the inclined block 19 upward under the action of the driving force, the stop block 17 moves into the interior of the opening slot 15 under the force provided by the spring 16, so that the outer end of the stop block 17 is away from the adjacent teeth of the toothed plate 14. This facilitates the toothed plate 14 to rotate and adjust the positioning plate 13. Then, through the control of the drive system, the lifting block 18 moves the inclined block 19 downward. The inclined surface at the bottom of the inclined block 19 is in contact with the side wall of the stop block 17, which moves the stop block 17 out toward the outer end of the opening slot 15 and into the space between the adjacent teeth of the toothed plate 14, thus limiting and fixing the toothed plate 14 and the positioning plate 13.

[0028] In actual use, after the fixed lifting frame 2 and the movable lifting frame 3 drive the clamping block 4 to move away from each other and open, the first threaded rod 6 is rotated by the drive system, which facilitates the horizontal movement of the movable plate 8 of the positioning component 7 inside the transverse groove 5. Then, the drive motor 11 provides driving force to the second threaded rod 12, causing the second threaded rod 12 to rotate, which in turn facilitates the movement of the movable plate 10 inside the long groove 9, making it easy to send the positioning plate 13 at the outer end of the movable plate 10 into the clamping block 4 for use. When the lifting block 18 moves the inclined block 19 upward under the action of the driving force, the stop block 17 moves to the opening groove 1 under the force provided by the spring 16. Inside 5, the outer end of the stop block 17 is moved away from the adjacent teeth of the toothed plate 14, so that the toothed plate 14 can rotate and adjust the angle of the positioning plate 13. Then, the lifting block 18 drives the inclined block 19 to move downward through the control of the drive system. The inclined surface at the bottom of the inclined block 19 is in contact with the side wall of the stop block 17, so that the stop block 17 is moved out toward the outer end of the opening slot 15 and moved between the adjacent teeth of the toothed plate 14. The toothed plate 14 and the positioning plate 13 are limited and fixed, so that the anchor chain can be moved to the inner center of the clamping block 4 through the inclination of the positioning plate 13. After the anchor chain is clamped by the clamping block 4, it is easy to weld quickly and accurately, improving the welding speed and accuracy.
