Description

Technical Field

[0001] This utility model relates to the field of welding construction technology, specifically to a positioning device for welding L-shaped anchor bars and angle steel. Background Technology

[0002] In the combined construction of precast double-T beams and cast-in-place walls, part of the wall's embedded components needs to be embedded in the concrete for anchoring, while the exposed portion is used to connect the ends of the precast double-T beams. During the fabrication of these embedded components, a common welding method relies on welding multiple L-shaped anchor bars to the corners of the angle steel. Currently, this method requires three workers: one to straighten the angle steel so its corner faces the ground, another to straighten the L-shaped anchor bars so they are vertically aligned with the corner, and a third to perform the welding. This method is labor-intensive, inefficient, and time-consuming, making it unsuitable for mass production. Furthermore, it is difficult to accurately position the anchor bars, leading to uncontrolled positioning accuracy and suboptimal welding results. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a positioning device for welding L-shaped anchor bars and angle steel, which reduces labor costs, improves work efficiency, helps meet the needs of mass production, has high positioning accuracy, and improves welding effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A positioning device for welding L-shaped anchor bars to angle steel includes a support platform, a positioning seat, and a support frame. The positioning seat and the support frame are spaced apart on the support platform. The top of the positioning seat is provided with a V-shaped positioning groove for placing the angle steel, and the angle bisector of the V-shaped positioning groove is vertically arranged. The top of the support frame is provided with a cantilevered frame extending towards one side of the positioning seat. The end of the cantilevered frame away from the support frame is provided with a vertical positioning surface. The distance between the vertical positioning surface and the angle bisector is equal to the radius of the L-shaped anchor bar. The top of the cantilevered frame is provided with a plurality of transversely spaced transverse positioning elements and a height alignment element for aligning the welding height of the L-shaped anchor bar.

[0005] As a further improvement to the above technical solution: The cantilever frame is provided with support plates at both ends in the cantilever direction. The top of the cantilever frame forms an avoidance groove between the two support plates. The lateral positioning member is fixed on the support plate and spans across the avoidance groove. Each of the height-aligning members is correspondingly arranged on each lateral positioning member. The vertical positioning surface is formed on the outer side of the corresponding support plate.

[0006] The lateral positioning element is perpendicular to the length direction of the V-shaped positioning groove.

[0007] The lateral positioning component is a cylindrical rod.

[0008] The height-adjusting component is a cylindrical rod that is vertically coplanar with the lateral positioning component.

[0009] The end of the alignment component away from the vertical positioning surface is provided with an alignment surface.

[0010] The cantilever bracket is provided with an extension panel below the vertical positioning surface, and the outer side of the extension panel forms an additional positioning surface that is coplanar with the vertical positioning surface.

[0011] The bottom of the positioning seat is fixed to the support platform, and the bottom of the support frame can be fixed to the support platform relative to the positioning seat, either close to or far away from it.

[0012] The support frame and the support platform are respectively provided with fixing bolts and strip grooves. The fixing bolts pass through the strip grooves to fix the support frame and the support platform. The length direction of the strip groove is perpendicular to the length direction of the V-shaped positioning groove.

[0013] The support platform is equipped with support legs at each of its four corners.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model relates to a positioning device for welding L-shaped anchor bars to angle steel. In use, the angle steel is placed in a V-shaped positioning groove, which is adapted to the angle steel to position it, ensuring the angle bisector is vertical. Next, the vertical walls of each L-shaped anchor bar are pressed tightly against the vertical positioning surface, and the horizontal walls of each L-shaped anchor bar are pressed tightly against the same-direction side of each horizontal positioning component, ensuring the horizontal walls of each L-shaped anchor bar are level with the alignment component. Then, the bottom of the vertical wall of each L-shaped anchor bar is welded to the angle steel, thus aligning the vertical walls of the L-shaped anchor bars with the center of the angle steel while maintaining the same height and orientation of the horizontal walls. Using this positioning device for welding L-shaped anchor bars to angle steel reduces labor costs, improves work efficiency, and helps meet the needs of mass production; furthermore, it offers high positioning accuracy, improving welding results.

[0022] Figure 1 and Figure 2This invention illustrates an embodiment of a positioning device for welding L-shaped anchor bars and angle steel. The positioning device includes a support platform 1, a positioning seat 2, and a support frame 3. The positioning seat 2 and the support frame 3 are spaced apart on the support platform 1. The top of the positioning seat 2 has a V-shaped positioning groove 5 for placing the angle steel 4. The angle bisector 51 of the V-shaped positioning groove 5 is vertically arranged. The top of the support frame 3 has a cantilevered frame 6 extending towards one side of the positioning seat 2. The end of the cantilevered frame 6 away from the support frame 3 has a vertical positioning surface 7. The distance between the vertical positioning surface 7 and the angle bisector 51 is equal to the radius of the L-shaped anchor bar 8. The top of the cantilevered frame 6 has multiple horizontally spaced horizontal positioning elements 9 and a height alignment element 10 for aligning the welding height of the L-shaped anchor bar 8.

[0023] In use, the angle steel 4 is placed in the V-shaped positioning groove 5, which fits the angle steel 4 to position it, ensuring the angle bisector of the angle steel 4 is vertical. Next, the vertical walls of each L-shaped anchor bar 8 are pressed tightly against the vertical positioning surface 7, and the horizontal walls of each L-shaped anchor bar 8 are pressed tightly against the same side of each transverse positioning component 9, ensuring the horizontal walls of each L-shaped anchor bar 8 are level with the height-aligning component 10. Then, the bottom of the vertical wall of each L-shaped anchor bar 8 is welded to the angle steel 4, thus aligning the vertical walls of the L-shaped anchor bars 8 with the center of the angle steel 4, maintaining the same height and consistent orientation of the horizontal walls of each L-shaped anchor bar 8. Using this positioning device for welding L-shaped anchor bars and angle steel reduces labor costs, improves work efficiency, and helps meet the needs of mass production; furthermore, it provides high positioning accuracy and improves welding results.

[0024] Furthermore, in this embodiment, the cantilever frame 6 is provided with support plates 61 at both ends in the cantilever direction. The top of the cantilever frame 6 forms a clearance groove 62 between the two support plates 61. The lateral positioning member 9 is fixed on the support plate 61 and spans across the clearance groove 62. Each pair of height members 10 is correspondingly set on each lateral positioning member 9. The vertical positioning surface 7 is formed on the outer side of the corresponding support plate 61. When unloading after the L-shaped anchor bar 8 and the angle steel 4 are welded, the whole structure is first moved upward by an appropriate distance, and then the bottom is turned outward (at this time, the clearance groove 62 provides clearance space for the horizontal wall of the L-shaped anchor bar 8 to turn downward) to an appropriate angle, and then the whole structure is pulled out to the side. Of course, if there is enough space, when unloading after the L-shaped anchor bar 8 and the angle steel 4 are welded, the whole structure is first moved upward by an appropriate distance, and then the whole structure is moved outward horizontally.

[0025] Furthermore, in this embodiment, the lateral positioning member 9 is perpendicular to the length direction of the V-shaped positioning groove 5.

[0026] Furthermore, in this embodiment, the lateral positioning member 9 is a cylindrical rod. Of course, in other embodiments, the lateral positioning member 9 may also be a square rod or a grooved rod, etc.

[0027] Furthermore, in this embodiment, the height-adjusting member 10 is a cylindrical rod that is vertically coplanar with the transverse positioning member 9. Vertical coplanarity means that the central axes of the height-adjusting member 10 and the transverse positioning member 9 lie on the same vertical plane. Of course, in other embodiments, the height-adjusting member 10 may also be a square rod or a grooved rod, etc.

[0028] Furthermore, in this embodiment, an alignment surface 101 is provided at the end of the tall component 10 that is away from the vertical positioning surface 7. During the welding process, the welding quality can be checked by ensuring that the end face of the horizontal wall of the L-shaped anchor bar 8 is flush with the bottom of the alignment surface 101. If they are flush, the welding quality is good; otherwise, it is poor.

[0029] Furthermore, in this embodiment, the cantilever frame 6 is provided with an additional panel 63 below the vertical positioning surface 7. The outer surface of the additional panel 63 forms an additional positioning surface 631 coplanar with the vertical positioning surface 7. Before welding, the vertical wall of each L-shaped anchor bar 8 is in close contact with both the vertical positioning surface 7 and the additional positioning surface 631. The additional positioning surface 631 can increase the positioning area and improve the positioning effect. In other embodiments, in order to improve positioning stability and prevent the L-shaped anchor bars 8 from swinging left and right, a slot can be provided on the vertical positioning surface 7 and / or the additional positioning surface 631 to hold the vertical wall of the L-shaped anchor bar 8.

[0030] Furthermore, in this embodiment, the bottom of the positioning seat 2 is fixed to the support platform 1, and the bottom of the support frame 3 can be fixed to the support platform 1 relative to the positioning seat 2, either closer to or further away from it. Preferably, the bottom of the positioning seat 2 is welded to the support platform 1. Since the bottom of the support frame 3 can be fixed to the support platform 1 relative to the positioning seat 2, the distance between the vertical positioning surface 7 and the angle bisector 51 of the V-shaped positioning groove 5 can be adjusted to meet the positioning requirements of L-shaped anchor bars 8 with different radii. Of course, the bottom of the support frame 3 can also be welded to the support platform 1 to meet the positioning requirements of L-shaped anchor bars 8 with a fixed radius.

[0031] Furthermore, in this embodiment, the support frame 3 and the support platform 1 are respectively provided with fixing bolts 11 and strip grooves 12. The fixing bolts 11 pass through the strip grooves 12 to fix the support frame 3 and the support platform 1. The length direction of the strip grooves 12 is perpendicular to the length direction of the V-shaped positioning groove 5. In this way, loosening the fixing bolts 11 allows the support frame 3 to be moved to adjust the distance between the vertical positioning surface 7 and the angle bisector 51 of the V-shaped positioning groove 5. After adjustment, the fixing bolts 11 are tightened. Preferably, the strip grooves 12 are provided on the support frame 3, and the fixing bolts 11 pass through the strip grooves 12 to fix the support frame 3 and the support platform 1. Of course, the strip grooves 12 can also be provided on the support platform 1, or both the support frame 3 and the support platform 1 can be provided with strip grooves 12 to improve the range of movement and adjustment.

[0032] Furthermore, in this embodiment, support legs 13 are provided at the four corners of the support platform 1 to achieve a lifting effect, making it convenient for operators to stand on one side of the support platform 1 for operation.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
