[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] To address the problem that the welding positioning structure of existing composite busbars cannot meet the welding requirements of copper pillars of various specifications during welding, this application provides a welding positioning structure for composite busbars, which will be described below in conjunction with the accompanying drawings.
[0026] This application provides a welding positioning structure for the expansion joint of copper pillars and copper plates in auxiliary composite busbars. The structure includes a support platform 10, an expansion joint support fixture 20, and a center punch 30. The support platform 10 supports the entire expansion joint support fixture 20; the expansion joint support fixture 20 has multiple vertically arranged support parts, each at a different distance from the support platform 10 to accommodate the edge positions of the copper plates to be expanded at different heights; the center punch 30 is used to fix the copper pillar 40 into the mounting holes of the copper plate 50.
[0027] In this embodiment, by setting multiple support parts of different heights on the expansion joint support fixture 20, it can effectively adapt to copper plates 50 of various height specifications, thereby enabling one fixture to meet multiple welding requirements, improving the welding versatility of copper plates 50 of different specifications, and reducing production costs and management difficulty.
[0028] Furthermore, the support platform 10 can be made of high-strength steel to ensure its load-bearing capacity and stability. The punch 30 can be designed with a replaceable head to accommodate mounting holes for copper pillars 40 and copper plates 50 of different shapes and sizes. Through the above technical solutions, the composite busbar welding positioning structure of this embodiment can significantly improve welding efficiency, reduce time wasted due to tooling changes, and ensure the stability of welding quality.
[0029] In a preferred embodiment, the tooling body 21 of the expansion joint support tooling 20 has multiple stepped surfaces 22 on one side, and any two adjacent stepped surfaces 22 are connected by vertical surfaces 23, and the height of each vertical surface 23 is different.
[0030] The design of this stepped surface 22 allows the expansion joint support fixture 20 to more precisely adapt to copper plates 50 of different heights, and achieves stable support for the copper plate 50 through the height difference of the vertical surface 23. In practical applications, the number and height of the stepped surfaces 22 can be customized according to the specifications of the copper plate 50 to meet diverse production needs.
[0031] Furthermore, the step surface 22 can be designed in the shape of a rectangle, trapezoid, or other suitable geometry to increase its contact area and stability with the copper plate 50. The surface of the vertical surface 23 can be treated with anti-slip measures, such as adding patterns or coatings, to prevent the copper plate 50 from sliding during welding. In addition, the tooling body 21 can be manufactured using a one-piece molding process to ensure its structural strength and precision.
[0032] Through the above technical solution, the expansion joint support fixture 20 of this embodiment can significantly improve the positioning accuracy and stability of the composite busbar welding process, reduce welding errors, and improve product quality.
[0033] In some implementations, the topmost step surface 22 has the largest width among all the step surfaces 22, while the remaining step surfaces 22 have the same width.
[0034] This design allows the top stepped surface 22 to provide a larger support area, suitable for thicker copper plates 50, while the other stepped surfaces 22 are suitable for thinner copper plates 50. Through this differentiated design, the expansion joint support fixture 20 can more flexibly adapt to copper plates 50 of different thicknesses while maintaining the stability of the overall structure.
[0035] Furthermore, the width of the step surface 22 can be optimized according to the thickness range of the copper plate 50. For example, the width of the topmost step surface 22 can be designed to be 1.5 or 2 times the width of the other step surfaces 22 to ensure sufficient support capacity. In addition, the surface of the step surface 22 can be hardened to improve its wear resistance and service life.
[0036] Through the above technical solution, the expansion joint support fixture 20 of this embodiment can further improve the positioning accuracy and reliability in the composite busbar welding process, reduce welding problems caused by the thickness difference of copper plate 50, and improve production efficiency and product quality.
[0037] In some implementations, the tooling body 21 is manufactured as a single piece of stainless steel.
[0038] Stainless steel is a high-strength, corrosion-resistant, and wear-resistant material, which effectively improves the service life and reliability of the expansion joint support fixture 20. The one-piece molding manufacturing process ensures the structural accuracy and overall strength of the fixture body 21, reducing structural weaknesses caused by welding or splicing.
[0039] Furthermore, different grades of stainless steel can be selected according to actual needs, such as 304 stainless steel or 316 stainless steel, to meet different corrosion resistance and strength requirements. In addition, the surface of the tooling body 21 can be polished to improve its appearance quality and corrosion resistance.
[0040] Through the above technical solution, the expansion joint support fixture 20 of this embodiment can significantly improve its durability and stability, reduce production interruptions caused by fixture damage, and reduce maintenance costs.
[0041] In some embodiments, the punch 30 has a pointed head at the point where the copper plate 50 and the copper pillar 40 are joined.
[0042] The pointed tip design allows the punch 30 to more accurately fix the copper pillar 40 into the mounting hole of the copper plate 50, improving the accuracy of welding positioning. In practical applications, the pointed tip can be designed to be round, square, or conical to accommodate mounting holes of different shapes.
[0043] Furthermore, the dimensions of the pointed tip can be optimized according to the specifications of the copper pillar 40 and the copper plate 50. For example, the diameter of the pointed tip can be designed to be 1 / 2 or 2 / 3 of the diameter of the mounting hole to ensure that it can be smoothly inserted and fixed to the copper pillar 40. In addition, the surface of the pointed tip can be hardened to improve its wear resistance and service life.
[0044] Through the above technical solution, the punch 30 in this embodiment can significantly improve the positioning accuracy and reliability in the composite busbar welding process, reduce welding defects caused by inaccurate positioning, and improve product quality.
[0045] In some embodiments, the punch 30 is made of high-speed steel. High-speed steel possesses high strength, high hardness, and good wear resistance, effectively improving the service life and reliability of the punch 30. In practical applications, the high-speed steel punch 30 can maintain its shape and performance during high-frequency impacts, reducing positioning errors caused by wear.
[0046] Furthermore, the shank of the punch 30 can be designed as a detachable structure to facilitate the replacement of the tip. The shank and tip can be connected by threads or snap-fit to improve its flexibility and maintainability. In addition, the surface of the punch 30 can be coated, such as by nitriding or hard chrome plating, to further improve its wear resistance and corrosion resistance. Through the above technical solutions, the durability and reliability of the punch 30 can be significantly improved, welding problems caused by punch wear can be reduced, and production efficiency and product quality can be increased.
[0047] In some implementations, the angle between the pointed end and the horizontal plane where the expansion joint is to be located is 45°.
[0048] This 45° angle design allows the punch 30 to transmit force more evenly during the hammering process, reducing deformation of the copper pillar 40 or copper plate 50 caused by force concentration. Simultaneously, the 45° angle improves the stability and precision of the hammering, ensuring accurate connection between the copper pillar 40 and copper plate 50. Through the above technical solution, the punch 30 in this embodiment can significantly improve the positioning accuracy and reliability during the composite busbar welding process, reduce welding defects caused by uneven hammering force, and improve product quality.
[0049] In some implementations, the pointed tip can be designed as round, square, or conical to accommodate mounting holes of different shapes and welding requirements. A round pointed tip is suitable for round mounting holes, providing a uniform distribution of striking force and reducing damage to the copper pillar 40 and copper plate 50. A square pointed tip is suitable for square mounting holes, providing a larger contact area and higher positioning accuracy. A conical pointed tip is suitable for applications requiring step-by-step positioning, achieving more precise positioning through its beveled design.
[0050] Furthermore, the dimensions of the pointed tip can be optimized according to the size of the mounting hole. For example, the diameter of a round pointed tip can be designed to be 1 / 2 or 2 / 3 of the diameter of the mounting hole, and the side length of a square pointed tip can be designed to be 1 / 2 or 2 / 3 of the side length of the mounting hole. In addition, the surface of the pointed tip can be textured, such as by adding patterns or coatings, to improve its friction and wear resistance.
[0051] Through the above technical solution, the punch 30 in this embodiment can significantly improve the positioning accuracy and reliability in the composite busbar welding process, reduce welding problems caused by mismatch in tip shape, and improve product quality.
[0052] In some embodiments, the support platform 10 is a heavy-duty workbench with a horizontal support surface for supporting the expansion joint support fixture 20.
[0053] The heavy-duty worktable is designed to provide higher load-bearing capacity and stability, ensuring positioning accuracy during the welding process. In practical applications, the heavy-duty worktable can be manufactured using high-strength steel and fixed to the expansion support fixture 20 via welding or bolting.
[0054] Furthermore, the surface of the heavy-duty worktable can be treated with anti-slip features, such as adding patterns or coatings, to prevent the expansion joint support fixture 20 from sliding during welding. Additionally, the bottom of the heavy-duty worktable can be designed with an adjustable height structure, for example, through threaded adjustment or hydraulic support, to adapt to different welding environments and operational requirements.
[0055] Through the above technical solution, the support platform 10 of this embodiment can significantly improve the stability and reliability of the composite busbar welding positioning structure, reduce welding errors caused by platform instability, and improve product quality.
