[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 Figures 1-3An automatic welding device for wrought iron flower cages includes a first semicircular clamping plate 12, with two sets of first semicircular clamping plates 12 arranged in a left-right mirror image. A second semicircular clamping plate 14 is placed above the first semicircular clamping plate 12, and a first semicircular toothed ring 15 is fixedly installed on the top of the second semicircular clamping plate 14. The outer walls of the first semicircular clamping plates 12 and 14 are respectively evenly provided with a first clearance opening 121 and a second clearance opening 141. The top of the first semicircular toothed ring 15 is provided with a convex arc groove 151. When the two sets of first semicircular clamping plates 12 move inward and merge, they form a complete circular ring plate. Similarly, when the two sets of first connecting plates 13 move inward and merge, they form a complete circular ring plate. After the ring 15 moves inward and merges, it forms a complete toothed ring. At this time, the two sets of convex arc grooves 151 will connect with each other to form a convex ring groove. The top of the first semi-circular toothed ring 15 is slidably provided with a support plate 2, and the bottom of the support plate 2 is fixedly provided with a convex arc block 22. The convex arc block 22 is slidably provided in the convex arc groove 151. By sliding the convex arc block 22 in the convex arc groove 151, the support plate 2 is assisted to slide in a ring on the complete toothed ring. The bottom of the support plate 2 is rotatably provided with a gear 23, which meshes with the first semi-circular toothed ring 15. The first welding head 26 and the second welding head 27 are placed below the gear 23. The first welding head 26 and the second welding head 27 respectively connect with the second clearance opening 141 and the first... Corresponding to the clearance opening 121, a first connecting plate 13 is fixedly disposed between the first semicircular clamping plate 12 and the second semicircular clamping plate 14. When the first semicircular clamping plate 12 moves, the first connecting plate 13 drives the second semicircular clamping plate 14 to move synchronously, and the second semicircular clamping plate 14 drives the first semicircular gear ring 15 to move synchronously. The two sets of convex arc grooves 151 correspond to each other. A second stepper motor 21 is fixedly disposed on the top of the support plate 2. The output end of the second stepper motor 21 passes through the bottom of the support plate 2 and is connected to the gear 23. The second stepper motor 21 drives the gear 23 to rotate, thereby driving the gear 23 to rotate on the outer ring of the first semicircular gear ring 15, and thus driving the support plate 2 to rotate on the first semicircular gear ring 15. The top slides, and at the same time, the convex arc block 22 slides in the convex arc groove 151 through the support plate 2. A second connecting plate 24 is fixedly installed on the bottom right side of the support plate 2. An electric telescopic rod 28 is fixedly installed on the right side of the second connecting plate 24. The telescopic end of the electric telescopic rod 28 passes through the left side of the second connecting plate 24 and is connected to the sliding plate 241. The first welding head 26 and the second welding head 27 are both fixedly installed on the left side of the sliding plate 241. Two sets of guide holes are evenly opened through the right side of the second connecting plate 24. Two sets of guide posts 25 are evenly fixedly installed on the right side of the sliding plate 241. The right side of the guide post 25 passes through the guide hole, and the guide post 25 assists the sliding plate 241 to move stably.

[0020] A base 1 is placed at the bottom of each of the two sets of first semicircular clamping plates 12. A sliding groove is formed at the top of the base 1, and a bidirectional lead screw 111 is rotatably mounted within the groove. Two sets of internally threaded sliders 112 are evenly screwed onto the outer wall of the bidirectional lead screw 111. The first semicircular clamping plates 12 are fixedly mounted on the top of the internally threaded sliders 112. A first stepper motor 11 is fixedly mounted on the right side of the base 1. The output end of the first stepper motor 11 passes through the right side of the base 1 and connects to the bidirectional lead screw 111, driving the bidirectional lead screw through the first stepper motor 11. Rotating 111 drives two sets of internal threaded sliders 112 to move inward synchronously via the bidirectional lead screw 111, thereby driving two sets of first semi-circular clamps 12 to move inward synchronously. The bottom of the second connecting plate 24 is in contact with the top of the base 1. The top of the base 1 is equipped with a cage bottom 32, the top of the cage bottom 32 is equipped with a cage frame 3, and the top of the cage frame 3 is equipped with a cage top 31. The second clearance opening 141 corresponds to the connection between the cage top 31 and the cage frame 3, and the first clearance opening 121 corresponds to the connection between the cage frame 3 and the cage bottom 32.

[0021] Working principle: The cage bottom 32 is placed on the base 1 and positioned between the two sets of first semicircular clamping plates 12. Then, the cage frame 3 is placed on the cage bottom 32, and the cage top 31 is placed on the cage frame 3. The first stepper motor 11 drives the bidirectional lead screw 111 to rotate, which in turn drives the two sets of internal threaded sliders 112 to move inward synchronously. This causes the two sets of first semicircular clamping plates 12 to move inward synchronously. When the first semicircular clamping plates 12 move, the first connecting plate 13 drives the second semicircular clamping plate 14 to move synchronously. The second semicircular clamping plate 14 then drives the first semicircular toothed ring 15 to move synchronously. At this time, the two sets of first semicircular clamping plates 12 will clamp and fix the cage frame 3 and the cage bottom 32 in the center, and the two sets of second semicircular clamping plates 14 will clamp and fix the cage frame 3 and the cage top 31 in the center. This ensures that the cage frame 3, the cage top 31, and the cage bottom 32 are in a stable state during the welding process, thereby ensuring the quality of the welding.

[0022] When the two sets of first semicircular clamping plates 12 move inward and merge, they form a complete circular ring plate. Similarly, when the two sets of first connecting plates 13 move inward and merge, they form a complete circular ring plate. Similarly, when the two sets of first semicircular toothed rings 15 move inward and merge, they form a complete toothed ring. At this time, the two sets of convex arc grooves 151 will connect with each other to form a convex annular groove. The second stepper motor 21 drives the gear 23 to rotate, thereby driving the gear 23 to rotate on the outer ring of the first semicircular toothed ring 15, which in turn drives the support plate 2 to slide on the top of the first semicircular toothed ring 15. At the same time, the support plate 2 drives the convex arc block 22 to slide in the convex arc groove 151. The sliding of the convex arc block 22 in the convex arc groove 151 assists the support plate 2 in making annular sliding on the complete toothed ring. As the support plate 2 makes annular movement, it will drive the first welding head 26 and the second welding head 27 on the outer side of the second connecting plate 24 to move synchronously. When the first welding head 26 and the second welding head 27 move in annular motion, the first welding head 26 and the second welding head 27 on the outer side of the second connecting plate 24 will move synchronously. After the second welding head 27 is aligned with the second clearance opening 141 and the first clearance opening 121 respectively, the sliding plate 241 is moved by the electric telescopic rod 28. In this way, the sliding plate 241 drives the first welding head 26 and the second welding head 27 to pass through the second clearance opening 141 and the first clearance opening 121 respectively, and contact the connection between the cage top 31 and the cage frame 3 and the connection between the cage frame 3 and the cage bottom 32 respectively, so as to perform welding. The second stepper motor 21 drives the first welding head 26 and the second welding head 27 to perform a circular motion on the outer ring of the connection between the cage top 31 and the cage frame 3 and the connection between the cage frame 3 and the cage bottom 32. In conjunction with the second clearance opening 141 and the first clearance opening 121 opened in the circular array, the connection between the cage top 31 and the cage frame 3 and the connection between the cage frame 3 and the cage bottom 32 are simultaneously and uniformly spot welded, which improves the welding efficiency and ensures the uniformity of the weld distribution.
