Description

Technical Field

[0001] This utility model relates to the field of welding positioning equipment, specifically a precision positioning device for steel frame beam assembly and welding. Background Technology

[0002] Steel frame beams are common main components of steel structure buildings. They are fixed by welding to form a load-bearing system. Currently, steel frame beams are installed by hoisting them to a designated height with a crane so that they overlap with the welded parts of other steel structures. During the welding and installation of steel frame beams, they are in a suspended state, which makes them prone to swaying and unstable, and it is not convenient to form an effective welded fixation.

[0003] According to the patent document with publication number CN212398610U, a precise positioning and anti-deformation device for welding the end plate of an H-beam includes a support platform and an adjustment and fixing device. The support platform is used to place the H-beam, and the adjustment and fixing device is used to adjust the longitudinal and horizontal positions of the end plate. When using this technical solution, it avoids the deviation between the actual node form and the designed node form, ensures the stress performance of the actual component, and can increase the temporary stiffness before welding, effectively avoiding the phenomenon of end plate welding deformation caused by residual stress generated during welding. Regarding the above technical solution, although the welding stiffness is increased, it cannot achieve multi-directional displacement adjustment of the two connection points during welding, which is inconvenient in use.

In addition, the vertical movement of the pressing seat controls the vertical misalignment adjustment of the two connection points, and the vertical movement of the movable plate provides planar support for the welding point.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning device for steel frame beam assembly and welding, comprising a support base, a fixed base welded to the top of the support base, openings at both ends of the fixed base, a movable base movably installed inside the openings, a slot on the movable base, a support frame welded to the fixed base, a connecting groove on the side of the support frame, a steel cable fixed inside the slot, one end of the steel cable movably installed inside the connecting groove, a fixed groove on the fixed base, and a limiting seat movably installed inside the fixed groove.

[0006] Furthermore, the support frame has a limiting groove, and a limiting block is movably installed inside the limiting groove. One end of the limiting block is fixed to the limiting seat, and an exhaust assembly is fixedly installed on the support frame.

[0007] Furthermore, a reinforcing block is welded onto the limiting block, and a threaded column is rotatably mounted on the reinforcing block, the threaded column being movably installed inside the limiting groove.

[0008] Furthermore, one end of the steel cable is fixed to the reinforcing block, and a support wheel is rotatably installed inside the connecting groove. The support wheel is installed inside the support frame via a rotating column, and the support wheel is in movable cooperation with the steel cable.

[0009] Furthermore, a lifting mechanism is fixedly installed between the support base and the fixed base, and a telescopic column is installed on the lifting mechanism. A movable plate is fixed to one end of the telescopic column, and the movable plate is movably installed between the support frames.

[0010] Furthermore, a fixing plate is welded to the bottom of the movable seat, and a displacement mechanism is fixed on the fixing plate, with one end of the displacement mechanism fixed to the support seat.

[0011] Furthermore, a groove is formed on the inner wall of the opening, and a slider is movably installed inside the groove, with one end of the slider fixed to the movable seat.

[0012] Furthermore, a threaded seat is fixed to the top of the support frame, and a threaded rod is rotatably installed inside the threaded seat. A pressing seat is movably installed at one end of the threaded rod, and the pressing seat is mounted on the threaded rod through a bearing seat.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a precise positioning device for steel frame beam assembly and welding, including a support base 1, a fixed base 2 welded to the top of the support base 1, openings 3 at both ends of the fixed base 2, a movable base 4 movably installed inside the openings 3, a slot 6 on the movable base 4, a support frame 8 welded to the fixed base 2, a connecting groove 10 on the side of the support frame 8, a steel cable 7 fixed inside the slot 6, one end of the steel cable 7 movably installed inside the connecting groove 10, a fixed groove 11 on the fixed base 2, a limiting seat 16 movably installed inside the fixed groove 11, a limiting groove 12 on the support frame 8, a limiting block 18 movably installed inside the limiting groove 12, one end of the limiting block 18 fixed to the limiting seat 16, and a ventilation assembly 9 fixedly installed on the support frame 8, the ventilation assembly 9 including a fan and a filter screen, the fan drawing air outward to quickly discharge the fumes between the support frames 8 to both sides.

[0025] In this embodiment, a reinforcing block 19 is welded onto the limiting block 18, and a threaded column 17 is rotatably mounted on the reinforcing block 19. The threaded column 17 is movably mounted inside the limiting groove 12. One end of the steel cable 7 is fixed to the reinforcing block 19. A support wheel 23 is rotatably mounted inside the connecting groove 10. The support wheel 23 is mounted inside the support frame 8 via a rotating column 24. The support wheel 23 movably cooperates with the steel cable 7. A lifting mechanism 26 is fixedly mounted between the support seat 1 and the fixed seat 2. A telescopic column is mounted on the lifting mechanism 26, and a movable plate 25 is fixed to one end of the telescopic column. The movable plate 25 is movably mounted between the support frames 8. Both the lifting mechanism 26 and the displacement mechanism 20 are linear reciprocating electric push rods. The lifting mechanism 26 pushes the movable plate 25 upward to provide planar support for the connection points at both ends of the workpiece, facilitating rapid alignment of the two ends of the workpiece later.

[0026] In this embodiment, a fixed plate 5 is welded to the bottom of the movable seat 4, and a displacement mechanism 20 is fixed on the fixed plate 5. One end of the displacement mechanism 20 is fixed to the support seat 1. A sliding groove 21 is opened on the inner wall of the opening 3. A slider 22 is movably installed inside the sliding groove 21. One end of the slider 22 is fixed to the movable seat 4. A threaded seat 14 is fixed to the top of the support frame 8. A threaded rod 15 is rotatably installed inside the threaded seat 14. A pressing seat 13 is movably installed at one end of the threaded rod 15. The pressing seat 13 is mounted on the threaded rod 15 through a bearing seat. The rotation of the threaded rod 15 pushes the pressing seat 13 downward through the bearing seat. The downward movement of the pressing seat 13 controls the upward movement distance of the limiting seat 16. The clamping and fixing of workpieces of different thicknesses is completed by adjusting the distance.

[0027] When using this device, firstly, place both ends of the steel frame beam workpiece on the fixed seat 2, with both ends of the workpiece located inside the support frame 8. Initially, adjust the starting position of the extrusion seat 13 according to the thickness of the workpiece. Rotate the threaded rod 15 to push the extrusion seat 13 downward. The downward movement of the extrusion seat 13 controls the height of the limit seat 16. After the extrusion seat 13 has moved downward and adjusted, activate the displacement mechanism 20. The displacement mechanism 20 pushes the movable seat 4 to the side through the fixed plate 5. The movement of the movable seat 4 changes the contact position with the workpiece, increasing the support area for the workpiece. As the movable seat 4 moves, the steel cable 7 moves, sliding on the connecting groove 10 and the support wheel 23. The sliding of the steel cable 7 drives the reinforcing block 19 and the limit block. When the limiting block 18 moves upward, the limiting seat 16 pushes the workpiece upward. The workpiece moves to the bottom of the extrusion seat 13 and is fixed. Before the workpiece is clamped and fixed, the threaded column 17 is rotated. The threaded column 17 pushes the workpiece to move left and right between the limiting seat 16 and the extrusion seat 13. The left and right adjustment of the workpiece makes the connection point quickly aligned. After the workpiece connection point is aligned, the limiting seat 16 moves upward to complete the clamping and fixing. The worker holds the welding gun to complete the welding of the workpiece. During welding, the exhaust component 9 works to quickly exhaust the fumes generated during welding to both sides to avoid the fumes from accumulating and obstructing the worker's vision. After welding, the limiting seat 16 descends, and the workpiece is retrieved and used later.
