[0002] The oil manifold in a transformer finned radiator is a key component of the transformer cooling system. It primarily collects and guides the circulating flow of cooling oil between the fins. Its welding quality directly affects the overall sealing performance, heat exchange efficiency, and operational safety of the transformer. During transformer manufacturing, the welding between the oil manifold and the fins is a core assembly step, demanding extremely high standards for weld uniformity, density, and structural strength. Especially in automated welding processes, ensuring the stable positioning and precise alignment of the oil manifold during welding becomes a critical factor influencing both welding quality and production efficiency.

[0003] While utility model patent CN 211248987 U improves the convenience and quality of welding operations to some extent by incorporating a rotatable base and a straightening device, it still has significant shortcomings in practical use. The device lacks a centering and limiting structure for the steel pipe on the base, making it difficult to accurately align the oil collecting pipe during initial placement. Furthermore, it is prone to shifting or shaking during rotational welding, leading to uneven welds, incomplete welds, or even welding failures. These problems not only reduce welding efficiency but also increase rework rates and the degree of manual intervention, severely impacting the stability and consistency of automated welding processes and failing to meet the actual needs of large-scale, high-precision transformer manufacturing.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example

[0022] Please see Figure 1-5 As shown, an automated welding equipment for the oil collection pipe of a transformer plate radiator in this embodiment includes a base 1 and a top plate 3. The bottom of the top plate 3 is connected to the top of the base 1 through several support rods 2. A positioning cone 6 is provided at the bottom of the top plate 3, and a bearing plate 5 is provided at the top of the base 1.

[0023] The positioning cone 6 is connected to the top of the top plate 3 through a vertical lifting structure. The positioning cone 6 is rotatably connected to the output end of the vertical lifting structure. The bottom of the bearing plate 5 is rotatably connected to the top of the base 1 through a drive assembly. A central column 13 is connected to the top of the bearing plate 5. A stepped groove 14 is opened on the top of the central column 13. Several upright plates 10 are arranged around the outer ring of the central column 13. Each upright plate 10 has an abutting column 12 on one side. The abutting column 12 is connected to the upright plate 10 through a horizontal adjustment structure.

[0024] The workflow is as follows: Before welding, the oil collection pipe to be welded is placed on the central column 13 at the top of the support plate 5, and the initial positioning and support are achieved through the stepped groove 14 at the top. The outer wall of the oil collection pipe contacts the abutting column 12 on the vertical plate 10. The abutting column 12 can be finely adjusted along the vertical plate 10 through the horizontal adjustment structure to accommodate oil collection pipes of different diameters and ensure that it is stably clamped in the center position of the support plate 5. Subsequently, the positioning cone 6 set at the bottom of the top plate 3 moves downward through the vertical lifting structure and is inserted into the inner hole of the oil collection pipe to further achieve axial centering and vertical fixation, thereby improving the overall assembly accuracy. At the same time, the support plate 5 is rotatably connected to the base 1 through the driving component at the bottom. During the welding process, the driving component drives the support plate 5 and the oil collection pipe to rotate synchronously, so that the welding gun can uniformly and continuously weld the circumferential weld of the oil collection pipe, ensuring the consistency and integrity of the welding quality. Example

[0025] Please see Figure 1-5 As shown in this embodiment, an automated welding equipment for the oil collection pipe of a transformer plate radiator includes a vertical lifting structure comprising a lifting cylinder 9, a lifting plate 7, and a mounting plate 8. The lifting cylinder 9 is mounted on the top of the top plate 3, and the lifting plate 7 is located at the bottom of the top plate 3. The bottom of the mounting plate 8 is detachably connected to the positioning cone 6, and the top of the mounting plate 8 is detachably connected to the lifting plate 7. The output end of the lifting cylinder 9 is connected to the top of the lifting plate 7. Specifically, through the coordinated arrangement of the lifting cylinder 9, the lifting plate 7, and the mounting plate 8 in the vertical lifting structure, during operation, the lifting cylinder 9 is activated, and its output end pushes the lifting plate 7 downward along the direction of the support rod 2, thereby causing the mounting plate 8 and the positioning cone 6 to descend synchronously and insert into the inner hole of the oil collection pipe to achieve axial alignment and clamping operation. This achieves the effect of improving positioning accuracy and clamping stability, ensuring positional consistency during the welding process.

[0026] Each support rod 2 has a sliding sleeve 15 slidably connected to its outer ring. Each sliding sleeve 15 has a connecting rod 16 fixedly connected to one side. One end of the connecting rod 16 is fixedly connected to the lifting plate 7. The bottom of the mounting plate 8 is rotatably connected to a docking sleeve 19. The top of the positioning cone 6 is fixedly connected to a docking post 20. The docking post 20 is bolted to the inside of the docking sleeve 19. Specifically, through the cooperation between the sliding sleeve 15 and connecting rod 16 slidably connected to the outer ring of each support rod 2, the docking sleeve 19 rotatably connected to the bottom of the mounting plate 8, and the docking post 20 at the top of the positioning cone 6, the sliding sleeve 15 and connecting rod 16 provide guiding support for the lifting plate 7 during the lifting process. At the same time, the docking post 20 and docking sleeve 19 ensure that the positioning cone 6 maintains a stable angle during the lifting process, thereby enhancing the smooth operation and positioning reliability of the lifting structure.

[0027] The top of the mounting plate 8 is connected to several positioning screws 18, and the top of the lifting plate 7 is provided with several through holes that are adapted to the positioning screws 18. One end of the positioning screw 18 is threadedly connected to a positioning nut 17. Specifically, by the cooperation between the several positioning screws 18 connected to the top of the mounting plate 8 and the through holes provided on the top of the lifting plate 7, and by locking them with the positioning nuts 17, the mounting plate 8 can be quickly disassembled and installed when replacing positioning cones 6 of different specifications or when performing equipment maintenance. This achieves the effect of improving the convenience of equipment maintenance and modular adaptability, and meets the welding requirements of multi-specification oil pipes. Example

[0028] Please see Figure 1-5 As shown in this embodiment, an automated welding equipment for the oil collection pipe of a transformer plate radiator includes a drive assembly comprising a drive motor 4 mounted on the bottom of a base 1. The output shaft of the drive motor 4 is connected to the bottom of a support plate 5. Specifically, through the design of the drive motor 4 mounted on the bottom of the base 1 and its output shaft connected to the bottom of the support plate 5, during the welding process, the drive motor 4 drives the support plate 5 and the oil collection pipe on it to rotate synchronously, so that the welding torch can evenly cover the circumferential area of ​​the weld, thereby improving the welding uniformity and work efficiency, and enhancing the automation level of the equipment and the consistency of welding quality.

[0029] The horizontal adjustment structure includes an adjusting screw 11. One end of the adjusting screw 11 is threaded through the vertical plate 10, and the other end is connected to the abutment post 12. Both the abutment post 12 and the outer ring of the positioning cone 6 are connected to rubber pads. Specifically, by using the design of the adjusting screw 11 passing through the vertical plate 10 and connecting to the abutment post 12, and both the abutment post 12 and the positioning cone 6 having rubber pads on their outer rings, when clamping oil collection pipes of different diameters, the position of the abutment post 12 can be finely adjusted by adjusting the adjusting screw 11 to make it fit against the outer wall of the oil collection pipe. The rubber pads play a buffering and protective role, preventing damage to the workpiece surface, thus improving the clamping adaptability and protecting the integrity of the workpiece.

[0030] The overall structure of this automated welding equipment for the oil manifold of the transformer plate radiator includes key components such as base 1, top plate 3, support rod 2, positioning cone 6, bearing plate 5, vertical lifting structure, drive assembly, centering column 13, stepped groove 14, upright plate 10, contact column 12, horizontal adjustment structure, lifting cylinder 9, lifting plate 7, mounting plate 8, sliding sleeve 15, connecting rod 16, docking sleeve 19, docking column 20, adjusting screw 11, rubber pad, positioning screw 18, and positioning nut 17. In actual operation, the oil collection pipe to be welded is first placed on the central column 13 at the top of the bearing plate 5, and initial positioning and support are achieved through the stepped groove 14 at its top; then, the outer wall of the oil collection pipe is clamped and limited by the abutment column 12 on the vertical plate 10. The position of the abutment column 12 can be finely adjusted along the direction of the vertical plate 10 by adjusting the screw 11 to adapt to oil collection pipes of different diameters and ensure that it is stably clamped in the center position of the bearing plate 5; at the same time, the bottom of the top plate 3 is provided with a positioning cone 6, which drives the lifting plate 7 and the mounting plate 8 to move downward through the lifting cylinder 9 in the vertical lifting structure, so that the positioning cone 6 is inserted into the inner hole of the oil collection pipe, further realizing axial centering and clamping operation, and improving the overall assembly accuracy; in order to ensure the circumferential uniformity of the weld, the bearing plate 13 is positioned by adjusting the screw 14 at the top of the vertical plate 5. A drive motor 4 is connected to the bottom of plate 5. The drive motor 4 drives the bearing plate 5 and its oil collection pipe to rotate synchronously, so that the welding torch can complete the welding operation continuously and evenly. In addition, during the lifting process, the sliding sleeve 15 and the connecting rod 16 slidably connected to the outer ring of the support rod 2 provide guide support for the lifting plate 7. The mating sleeve 19 at the bottom of the mounting plate 8 cooperates with the mating post 20 at the top of the positioning cone 6 to ensure that the positioning cone 6 maintains a stable angle during the lifting process. The top of the mounting plate 8 is provided with a positioning screw 18, which cooperates with the through hole at the top of the lifting plate 7 and is locked by the positioning nut 17, which facilitates quick disassembly and assembly of the mounting plate 8 and replacement of positioning cones 6 of different specifications. At the same time, the abutment post 12 and the outer ring of the positioning cone 6 are provided with rubber pads to provide cushioning protection and prevent damage to the surface of the workpiece.

[0031] The design of this welding equipment fully solves the core problems existing in the prior art, namely that traditional welding devices do not have a centering limit structure for the steel pipe, which makes it difficult to accurately center the oil collection pipe when it is initially placed, and it is easy to deviate or shake during the welding process, resulting in uneven welds, missed welds and other problems. By introducing the cooperative structure of the centering column 13 and the stepped groove 14, combined with the multi-point limiting clamping mechanism composed of the vertical plate 10 and the adjustable abutment column 12, the precise centering and stable clamping of the oil collection pipe are achieved, significantly improving the stability and positioning accuracy during the welding process. At the same time, the positioning cone 6 achieves auxiliary centering and clamping functions through the vertical lifting structure, and ensures the consistency of its angle through the docking column 20 and the docking sleeve 19, further enhancing the clamping reliability. The design of the drive component driving the bearing plate 5 to rotate gives the welding operation good circumferential coverage capability, improving welding efficiency and weld quality consistency. The combination design of the adjusting screw 11 and the rubber pad in the horizontal adjustment structure not only improves the clamping adaptability, but also effectively protects the workpiece surface from damage. The mounting plate 8 and the lifting plate 7 can be quickly disassembled and replaced through the positioning screw 18 and the positioning nut 17, enhancing the convenience of equipment maintenance and modular adaptability, and meeting the welding needs of oil collection pipes of various specifications.
