Description

Technical Field

[0001] The utility model relates to the field of steel structure processing, in particular to a positioning structure for steel structure welding. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welding, bolts or rivets. Most steel structure welding positioning devices clamp the two steel structures to be welded by setting two sets of clamping components, and drive the two clamping components to move so that the clamped steel structures are close to each other and docked. However, during the processing, it is troublesome to clamp or remove the steel structure. When the steel structure needs to be axially docked, it is difficult to quickly align the centers of the two steel structures to be processed. Summary of the invention

[0003] The technical problem to be solved by the utility model is that it is troublesome to clamp or remove the steel structure during the processing. When the steel structure needs to be axially connected, it is difficult to quickly align the centers of the two steel structures to be processed.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a positioning structure for steel structure welding, including a welding chamber and a welding head, the top surface of the welding chamber is provided with a moving mechanism for driving the welding head to move, the bottom surface of the welding chamber is symmetrically and slidingly provided with two moving plates, the inner walls of the welding chamber are respectively provided with electric push rods for driving the moving plates to move, and positioning components are provided on the opposite sides of the two moving plates.

[0005] The beneficial effect of the utility model is that the electric push rod is provided to drive the moving plate to move, thereby facilitating the movement of the steel structure to be welded, and making the steel structures contact each other, which is convenient for subsequent welding.

[0006] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to quickly align the two steel structures where welding is required.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the positioning assembly includes a main splint and side splints hingedly arranged at both ends of the main splint, the two side splints are hingedly matched with the main splint through a hinge shaft, two first guide wheels are symmetrically arranged on one side of the main splint, a traction rope is wrapped around the middle of one of the side splints, one end of the traction rope passes around the two first guide wheels in turn and is wrapped and connected with the other side splint, the main splint is connected to the opposite side of the movable plate by a spring telescopic rod, and a second guide wheel matching the traction rope is provided on one side of the movable plate.

[0008] The beneficial effects of the above improvements are as follows: by setting the main clamping plate, the spring telescopic rod, the first guide wheel, the second guide wheel, the traction rope and the side clamping plate, the electric push rod can drive the movable plate to move, and then drive the main clamping plate to move, so that the two main clamping plates respectively abut the surfaces of the two steel structures to be welded, and push the two steel structures to move relative to each other until the two steel structures abut, and then as the electric push rod continues to work, the spring telescopic rod will be compressed, and then the second guide wheel will squeeze the traction rope to make the two side clamping plates deflect, thereby clamping the two sides of the steel structure, and in this process, the two steel structures will be driven to move toward the center to prepare for subsequent welding.

[0009] As a further improvement of the utility model, the technical problem to be solved is: the steel structure is difficult to move quickly.

[0010] In order to solve the above technical problems, the utility model further improves and adopts a technical solution as follows: a plurality of first rotating rollers are rotatably embedded on opposite sides of the two main splints.

[0011] The beneficial effect of the above improvement is: by setting up multiple first rotating rollers, the two main clamping plates can move relative to each other to clamp the steel structure, and the steel structure can slide smoothly between the two main clamping plates, which makes it easier for the side clamping plates to deflect and squeeze the steel structure, so that the steel structure is in the center position of the two main clamping plates, that is, the two steel structures to be welded are quickly aligned, making it convenient for the workers to perform welding.

[0012] As a further improvement of the utility model, the technical problem to be solved is: scratches are easily caused on the surface of the steel structure.

[0013] In order to solve the above technical problems, the utility model further improves and adopts a technical solution as follows: a second rotating roller is rotatably embedded in the inner side of one end of the side clamping plate away from the hinge shaft.

[0014] The beneficial effect of the above improvement is that by providing the second rotating roller, the side clamping plate drives the second rotating roller to roll in contact with the surface of the steel structure during the deflection process, thereby effectively avoiding scratches on the surface of the steel structure.

[0021] like Figure 1-3 As shown, a positioning structure for steel structure welding includes a welding chamber 1 and a welding head 2. A moving mechanism for driving the welding head 2 is provided on the top surface of the welding chamber 1. Two moving plates 4 are symmetrically slidably provided on the bottom surface of the welding chamber 1. Electric push rods 3 for driving the moving plates 4 are provided on the inner walls of the welding chamber 1. Positioning components are provided on opposite sides of the two moving plates 4. The electric push rods 3 are provided to drive the moving plates 4 to move, thereby facilitating the movement of the steel structure to be welded, and making the steel structures contact each other, which is convenient for subsequent welding.

[0022] The positioning assembly includes a main splint 5 and side splints 10 hinged at both ends of the main splint 5. The two side splints 10 are hingedly connected to the main splint 5 through a hinge shaft 13. Two first guide wheels 7 are symmetrically provided on one side of the main splint 5. A traction rope 9 is wrapped around the middle of one of the side splints 10. One end of the traction rope 9 passes around the two first guide wheels 7 in turn and is wrapped and connected with the other side splint 10. The main splint 5 is connected to the opposite side of the movable plate 4 through a spring telescopic rod 6. A second guide wheel 8 matching the traction rope 9 is provided on one side of the movable plate 4. By setting the main clamping plate 5, the spring telescopic rod 6, the first guide wheel 7, the second guide wheel 8, the traction rope 9 and the side clamping plate 10, the electric push rod 3 can work to drive the movable plate 4 to move, and then drive the main clamping plate 5 to move, so that the two main clamping plates 5 respectively abut the surfaces of the two steel structures to be welded, and push the two steel structures to move relative to each other until the two steel structures abut, and then as the electric push rod 3 continues to work, the spring telescopic rod 6 will be compressed, and then the second guide wheel 8 will squeeze the traction rope 9 to make the two side clamping plates 10 deflect, so as to clamp the two sides of the steel structure. In this process, the two steel structures will be driven to move toward the center to prepare for subsequent welding.

[0023] Embodiment 2:

[0024] Further optimization based on the above embodiment: Figure 1-3As shown, a plurality of first rotating rollers 11 are embedded in the two main plates 5 for rotation on one side relative to the other. By providing a plurality of first rotating rollers 11, after the two main plates 5 move relative to each other to clamp the steel structure, the steel structure can slide smoothly between the two main plates 5, thereby facilitating the side plates 10 to deflect and squeeze the steel structure, so that the steel structure is located at the center of the two main plates 5, that is, the two steel structures to be welded are quickly aligned, which is convenient for the workers to weld.

[0025] The side clamping plate 10 is rotatably embedded with a second rotating roller 12 at one end away from the hinge shaft 13. By setting the second rotating roller 12, the side clamping plate 10 drives the second rotating roller 12 to roll with the surface of the steel structure during the deflection process, effectively avoiding scratches on the surface of the steel structure.
