Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding, specifically to a tooling for welding filler sheets. Background Technology
[0002] The welding industry frequently encounters welding dissimilar metals. In such cases, welding strips are needed as transition welding materials. This process requires filling the gaps, and irregularly shaped welding strips are often encountered, making the filling process laborious and cumbersome. Current technology uses a cover plate and support platform for filling. The support platform has a placement groove, and the cover plate is placed inside the groove. Because of the welding strip filling, a gap must be left between the periphery of the cover plate and the inner wall of the placement groove. This allows the cover plate to move within the groove, resulting in uneven filling on one side, leaving the other side unfilled. This leads to poor weld quality, cracking, porosity, and ultimately, scrap, and is time-consuming and labor-intensive. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention
[0003] The purpose of this invention is to provide a tooling for welding filler sheets, which can uniformly fill the filler sheets and ensure welding quality.
[0004] To achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a tooling for welding filler sheets, characterized in that it includes a support platform and a cover plate, a placement groove is provided on the upper side of the support platform, the cover plate is disposed in the placement groove, a limiting step is provided between the bottom periphery of the cover plate and the inner wall of the placement groove, and a filling gap for filling the filler sheets is provided between the inner wall of the placement groove and the periphery of the cover plate.
[0005] As a preferred technical solution, the limiting step is connected to the bottom of the inner wall of the placement groove to form an integral step structure, and the limiting step abuts against the bottom of the periphery of the cover plate.
[0006] As a preferred technical solution, the limiting step is connected to the bottom periphery of the cover plate to form an integral step structure, and the limiting step abuts against the bottom of the inner wall of the placement groove.
[0007] As a preferred technical solution, the bottom surface of the placement groove is provided with an anti-cavity groove.
[0008] As a preferred technical solution, the cover plate is an elliptical ring, and the shape of the placement groove matches the shape of the cover plate.
[0009] The beneficial effects of this utility model are:
[0010] 1) The limiting step limits the cover plate, so that the cover plate will not move when the welding strip is filled in the filling gap. This avoids uneven filling of the welding strip and ensures uniform filling of the welding strip, thus ensuring welding quality.
[0011] 2) The limiting step is connected to the support platform, and the limiting step abuts against the bottom of the periphery of the cover plate to form a limit, so the cover plate cannot move during filling; or the limiting step is connected to the cover plate, and the limiting step abuts against the bottom of the inner wall of the placement groove to form a limit, so the cover plate cannot move during filling.
[0012] 3) The clearance groove serves to reduce weight;
[0013] 4) The cover plate is an elliptical ring, which makes it easy for the welded pieces to meet the shape requirements after welding. Attached Figure Description

[0024] Please see Figures 1-7 This utility model provides a tooling for welding filler sheets, including a support platform 1 and a cover plate 2. The support platform 1 has a placement groove 101 on its upper side, and the cover plate 2 is disposed in the placement groove 101. A limiting step 3 is provided between the bottom periphery of the cover plate 2 and the inner wall of the placement groove 101. A filling gap 4 for filling filler sheets is provided between the inner wall of the placement groove 101 and the periphery of the cover plate 2. The limiting step 3 limits the cover plate 2, so that the cover plate 2 will not move when the filler sheet is filled in the filling gap 4. This avoids uneven filling of the filler sheet, can uniformly fill the filler sheet, ensure welding quality, is simple and convenient to install, and improves production efficiency.
[0025] like Figures 1-7 As shown, there are two ways to set the limiting steps 3. The first way is to set the limiting steps 3 at the bottom of the inner walls on both sides of the placement groove 101. The limiting steps 3 are connected to the support platform 1 to form an integral step structure. In this way, the limiting steps 3 abut against the bottom of the periphery of the cover plate 2 to prevent the cover plate 2 from moving during filling. The second way is to set the limiting steps 3 at the bottom of both sides of the cover plate 2. The limiting steps 3 are connected to the bottom of the periphery of the cover plate 2 to form an integral step structure. In this way, the limiting steps 3 abut against the bottom of the periphery of the cover plate 2 to prevent the cover plate 2 from moving during filling, thereby preventing welding cracks and porosity that would cause scrap.
[0026] like Figures 1-7 As shown, the bottom surface of the placement groove 101 is provided with a void-avoiding groove 102, which serves to reduce weight and also to avoid voids.
[0027] like Figures 1-7As shown, the cover plate 2 is an elliptical ring, and the shape of the placement groove 101 matches the shape of the cover plate 2, which makes it suitable for welding irregular parts. Furthermore, the shape of the clearance groove 102 matches the shape of the placement groove 101, and it has good adaptability to the cover plate 2. Specifically, the bottom of the outer peripheral side and the bottom of the inner peripheral side of the cover plate 2 are respectively connected to the limiting steps 3. In this way, the limiting steps 3 on the outer peripheral side of the cover plate 2 abut against the inner wall of the corresponding placement groove 101, and a filling gap 4 is formed between the outer peripheral side of the cover plate 2 and the inner wall of the corresponding placement groove 101. The limiting steps 3 on the inner peripheral side of the cover plate 2 abut against the inner wall of the corresponding placement groove 101, and a filling gap 4 is formed between the limiting steps 3 on the inner peripheral side of the cover plate 2 and the inner wall of the corresponding placement groove 101. After filling, it can be welded into a first irregular part 5 and a second irregular part 6. The size of the first irregular part 5 is larger than that of the second irregular part 6.
[0028] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
