An end head is arranged at the center of the horizontal plane, the end head and the horizontal plane are of an integrated structure, arc-shaped edges are arranged on the surfaces of the two sides of the end head, and the arc-shaped edges make close contact with the outer wall of the R corner.

Description

Technical Field

[0001] The utility model relates to the technical field of welding seam filling, in particular to a welding seam filling structure. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure;

[0003] For example, the Chinese patent (steel plate welding frame) with announcement number CN211840734U includes a workpiece frame, a support frame, a pad, and a connecting channel steel; the pad is provided with a support frame, the support frame is provided with a workpiece frame, the outer side of the support frame is connected to the connecting channel steel, and the connecting channel steel connects the support frames in the same row together; the workpiece frame is arranged below the welding gun, and the workpiece frame includes a side edge and a bottom edge, and the side edge and the bottom edge are respectively arranged obliquely on the support frame, the side edge is connected to the bottom edge, and the angle between the side edge and the bottom edge is 90 degrees. The utility model places the steel plate obliquely through the steel plate welding frame, so that the welding surface of the steel plate is parallel to the horizontal plane, which is convenient for the welding gun to perform welding. The steel plate welding frame increases the contact area between the steel plate and the support surface, improves the stability of the steel plate during welding, and improves the welding quality. The support frames in the same row are connected together by connecting the channel steel, so that the structure of the steel plate welding frame is more stable.

[0004] However, the existing welding filling method is to fill the product joints with welding wire and then grind them. This method cannot meet the surface treatment requirements for special materials. For example, for brushed plates, the texture of the grinded area is significantly different from that of other parts of the product, resulting in poor welding filling effect. Therefore, it does not meet the existing needs. We have proposed a welding filling structure. Utility Model Content

[0005] The purpose of the utility model is to provide a welding caulking structure to solve the problem that the existing welding caulking method proposed in the above background technology is to fill the product joints with welding wire and then grind them, which cannot meet the surface treatment requirements for special materials. For example, for brushed plates, the texture of the grinded area is significantly different from that of other parts of the product, resulting in poor welding caulking effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding filling structure, comprising: a first workpiece, a second workpiece is arranged on one side of the first workpiece, an R angle is arranged at the bending connection between the first workpiece and the second workpiece, a filling piece is arranged at the opening of the R angle, the filling piece includes a horizontal plane, a first welding point is arranged at one end of the horizontal plane, and a second welding point is arranged at the other end of the horizontal plane.

[0007] Preferably, an end cap is provided at the center of the horizontal plane, and the end cap and the horizontal plane are an integral structure.

[0008] Preferably, both side surfaces of the end are provided with arcuate edges, and the arcuate edges are in close contact with the R-angle outer wall.

[0009] Preferably, the connection points between the two ends of the caulking piece and the first workpiece and the second workpiece are welded and fixed along the first welding point and the second welding point.

[0010] Preferably, the filler sheet material has the same appearance as the first workpiece and the second workpiece material, and the horizontal surface of the filler sheet is flat.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model uses a caulking piece to fill in the R angle, bends the first workpiece and the second workpiece as required, and forms an R angle after bending. The end of the caulking piece is filled into the inside of the R angle, and the arc edge is in close contact with the outer wall of the R angle. The R angle is covered by the caulking piece. At this time, the horizontal plane of the caulking piece is kept level with the first workpiece and the second workpiece, and then the two ends of the caulking piece are connected with the first workpiece and the second workpiece along the first welding point and the second welding point to weld them into one, so that there is no need for grinding or wire drawing. By welding after adding the caulking piece, the processing difficulty and processing time can be significantly reduced, and the product quality is improved. The existing welding caulking method is to fill the product joints with welding wire and then grind them, which cannot meet the surface treatment requirements for special materials. For example, for the wire drawing plate, the texture of the grinding part is significantly different from other parts of the product, resulting in poor welding caulking effect.
