Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a tool for assisting welding. Background Technology

[0002] Welders often face numerous challenging problems when performing steel plate welding. On one hand, weld detachment is frequent, primarily due to uneven heat distribution, improper welding parameter settings, or non-standard welding operations. This results in an insufficiently strong connection between the weld and the steel plate, making it prone to detachment. On the other hand, the steel plate is prone to warping during welding, possibly due to inherent stress in the plate or thermal expansion in the heat-affected zone. Warped steel not only compromises the flatness of the welded area but also prevents a proper weld joint, leading to substandard weld quality. To address these warped areas, welders often expend considerable time and effort, employing methods such as grinding and straightening. This increases the labor intensity and reduces efficiency, hindering the efficient and smooth completion of the welding process. These problems severely impact the quality and efficiency of steel plate welding, causing significant inconvenience to welding production and urgently requiring solutions. Utility Model Content

[0003] The purpose of this invention is to provide a tool to assist in welding.

[0004] The technical solution to achieve the purpose of this utility model is: a welding auxiliary tool, including a steel rod and a buckle installed below the front end of the steel rod; the buckle is provided with a workpiece limiting hole for inserting the workpiece and restricting its vertical movement; the front end of the steel rod is provided with an insertion hole, and the top wall of the buckle above the workpiece limiting hole is rotatably inserted into the insertion hole; the bottom of the steel rod is also fixed with a downwardly protruding workpiece pressing member; the workpiece pressing member and the buckle are arranged at a distance from each other along the length of the steel rod.

[0005] When weldable parts are found to be detached, warped, or otherwise unable to connect properly, or when welding two deformed workpieces is required, the auxiliary welding tool of this invention can be used to achieve a good connection during welding. One end of the workpiece is inserted into the locking hole of the workpiece, and the workpiece is pressed down by the workpiece pressing member (aligned with the warped or deformed part of the workpiece), flattening the warped or deformed part and sealing the joint before welding. This auxiliary welding tool of this invention has the advantages of simple operation, safety, and labor-saving.

[0006] Furthermore, the buckle is C-shaped or C-like in shape. In this case, the central hole of the buckle serves as a limiting hole for the workpiece to be welded. The C-shaped or C-like buckle facilitates disassembly and assembly, and also makes it easy to insert the workpiece into the limiting hole from one side opening of the buckle. Furthermore, the buckle is equipped with an anti-detachment component to prevent it from reversing out of the insertion hole.

[0007] Furthermore, the protrusion height of the pressing part of the workpiece to be welded is greater than or equal to the distance between the bottom surface of the steel rod and the bottom surface of the limiting hole of the workpiece to be welded, so as to facilitate the application of external force.

[0008] Furthermore, the pressing part of the workpiece to be welded is generally triangular pyramidal in shape, with the tip pointing downwards, and the tip has an arc-shaped chamfer design, forming a smooth arc transition, which can effectively disperse stress.

[0009] Furthermore, the steel rod is a steel pipe, and its lightweight design facilitates operation. Attached Figure Description

[0010] Figure 1 This is a three-dimensional structural diagram of the auxiliary welding tool described in an embodiment of the present invention;

[0011] Figure 2 This is a side view of the auxiliary welding tool described in an embodiment of the present invention;

[0012] Figure 3 This is a schematic diagram showing the usage state of the auxiliary welding tool described in the embodiment of this utility model. Detailed Implementation

[0013] The preferred embodiment of the auxiliary welding tool of this utility model will be described in detail below with reference to the accompanying drawings.

[0014] Combination Figure 1 and Figure 2 A welding auxiliary tool includes a steel rod 10 and a buckle 20 installed below the front end of the steel rod 10; the buckle 20 is provided with a workpiece limiting hole 30 for inserting a workpiece 100 (e.g., a steel plate) and restricting the vertical movement space of the workpiece 100; the front end of the steel rod 10 is provided with an insertion hole 11, and the top wall 21 of the buckle above the workpiece limiting hole 30 is rotatably inserted into the insertion hole 11; the bottom of the steel rod 10 is also fixed with a downwardly protruding workpiece pressing member 40; the workpiece pressing member 40 and the buckle 20 are arranged at a distance from each other in the length direction of the steel rod 10.

[0015] The buckle 20 is C-shaped or C-like in shape. The central hole of the buckle 20 serves as the limiting hole 30 for the workpiece to be welded. The upper end of the buckle 20 is provided with an anti-disengagement component 50 to prevent the buckle 20 from being disengaged from the insertion hole 11 in the opposite direction.

[0016] like Figure 3 As shown, when using the auxiliary welding tool of this utility model, one end of the workpiece 100 to be welded is inserted into the workpiece limiting hole 30 of the buckle 20. While the bottom surface of the end of the workpiece 100 remains in contact with the inner bottom surface of the buckle 20, an external force is applied to cause the steel rod 10 to swing downwards axially around the top wall 21 of the buckle as its swing center. This causes the workpiece pressing member 40 to press downwards against the workpiece 100 (the workpiece pressing member 40 is aligned with the raised or deformed part of the workpiece 100), so that the raised or deformed part of the workpiece 100 is flattened and the weld is closed, and then welding is performed. The auxiliary welding tool of this utility model has the advantages of simple operation, safety, and labor saving. Furthermore, the C-shaped or C-like buckle 20 is easy to disassemble and assemble, and also facilitates inserting the workpiece 100 into the workpiece limiting hole 30 from the opening side of the buckle 20.

[0017] Of course, the shape of the buckle of this utility model can be, but is not limited to, the specific shape shown in the drawings; it can also be other shapes, such as an O-shape. In specific implementation, the anti-disengagement component 50 can be a radial protrusion structure, a pin, or a nut, etc. For example, the radial protrusion structure can be locked onto the edge of the insertion hole 11 to prevent the buckle 20 from disengaging in the opposite direction; the pin can be inserted into the groove in the insertion hole 11 through an interference fit to play an anti-disengagement role; the nut can be threaded onto the buckle 20 to further fix the buckle 20 and prevent it from disengaging.

[0018] The workpiece pressing component 40 to be welded can be fixed to the bottom of the steel rod 10 by welding.

[0019] Furthermore, such as Figure 2 As shown, the protrusion height H of the workpiece pressing member 40 is greater than or equal to the distance L between the bottom surface of the steel rod and the bottom surface of the workpiece limiting hole 30, which facilitates the application of external force. Of course, the protrusion height H of the workpiece pressing member 40 can also be less than the distance L between the bottom surface of the steel rod and the inner bottom surface of the workpiece limiting hole 30, but in this case, the operating space is relatively smaller.

[0020] Furthermore, such as Figures 1-3 As shown, the workpiece pressing member 40 is generally in the shape of a triangular pyramid, with the tip 41 pointing downwards. The tip 41 has an arc-shaped chamfer design, forming a smooth arc transition, which can effectively disperse stress. Of course, the shape of the workpiece pressing member 40 can be, but is not limited to, the triangular pyramid shape shown in the figure, and its shape can be adjusted as needed.

[0021] Furthermore, the steel rod 10 is a hollow steel tube structure, and its lightweight design facilitates operation. Of course, the steel rod 10 can also be a solid rod structure.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
