Description

Technical Field

[0001] This invention relates to the field of steel support processing technology, specifically a welding device for steel support processing. Background Technology

[0002] Steel supports are structural members made of steel through welding, bolting, or machining. They are mainly used to support, fix, or connect other building, mechanical, or industrial equipment. Their core function is to provide stable mechanical support, ensuring the strength, rigidity, and durability of the overall structure. Steel supports are widely used in construction, bridges, tunnels, power facilities, petrochemicals, rail transportation, and heavy machinery, and are indispensable key components in modern engineering. Welding equipment for steel support fabrication is a specialized automated or semi-automated welding device used to manufacture steel structure support components, achieving permanent connections between components through high-temperature molten metal.

[0003] Patent CN219665499U discloses a welding device for processing steel supports. The device involves placing the steel support base plate to be welded on top of the base plate, rotating a threaded rod to slide an L-shaped clamping plate to hold it in place, then rotating a rotating rod to slide a vertical support plate, placing the steel support to be welded in front of the vertical support plate for support. A cylinder then moves a pressure plate downwards to press it firmly, and a cylinder moves the welding joint of a fixing plate closer to the welding point. A sliding rod then drives a welding gun to weld the steel support. This achieves the purpose of clamping, fixing, and automatically welding the steel support, improving welding efficiency. However, existing welding devices for processing steel supports have certain drawbacks. They typically only allow for straight-line butt welding of two sets of steel, resulting in limited welding flexibility and limitations. Therefore, this paper proposes a welding device for processing steel supports. Summary of the Invention

The inner wall of the movable ring is provided with a movable groove, and a limiting slip ring is located inside the movable groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By starting the first rotary motor on the moving carrier plate, the first rotating shaft is driven to rotate, which in turn drives the rotating disk to rotate under the cooperation of the movable ring plate and the annular groove. This causes the two sets of steel to rotate relative to each other until the angle between the two sets of steel is consistent with the target angle. The second fastening bolt and the locking hole are then engaged to fix the position of the rotating disk. Next, the docking motor on the bearing base is started to drive the two sets of first lead screw shafts to rotate together. Under the cooperation of the symmetrical external threads, the two sets of first sliding blocks move relative to each other along the two sets of sliding grooves, which in turn drives the two sets of moving carrier plates to move relative to each other until the welded parts of the two sets of steel are in contact. The first fastening bolt is then passed through the outer locking plate and engaged with the outer locking groove. This allows the two sets of steel to be welded at a specified angle according to actual needs, with a wide range of applications and significantly improved welding flexibility.

[0020] 2. By rotating the first rotating handle, the first threaded rod is rotated, thereby driving two sets of first moving blocks to move relative to each other along the limiting groove under the cooperation of the symmetrical threaded sections. This, in turn, drives two sets of limiting plates to move relative to each other until both sets of limiting plates are in contact with the steel. The first limiting bolt and the first limiting plate are connected by threads to ensure that the first limiting bolt is tightly fitted with the first rotating handle. Then, by rotating the second rotating handle, the second threaded rod is rotated, thereby driving two sets of second moving blocks to move relative to each other along the vertical groove under the cooperation of the symmetrical threaded sections. This, in turn, drives two sets of limiting bars to move relative to each other until all four sets of limiting bars are in contact with the steel. The second limiting bolt and the second limiting plate are connected by threads to ensure that the second limiting bolt is tightly fitted with the second rotating handle. This method is suitable for positioning two sets of steel of different sizes and ensures the welding stability of the two sets of steel.

[0021] 3. By activating the translation motor at the end of the transverse groove, the second lead screw shaft is rotated. This rotation, through the threaded connection between the second lead screw shaft and the second sliding block, causes the second sliding block to move along the transverse groove, which in turn causes the moving ring to move until the welding point of the two sets of steel is located at the center of the moving ring. The second lead screw shaft is then fixed by a positioning bolt. Next, the second rotary motor on the outside of the fixed plate is activated, causing the second rotating shaft and rotating gear to rotate together. This rotation, through the meshing rotating gear and the toothed ring, in conjunction with the limiting slip ring and the movable groove, causes the toothed ring to rotate, which in turn causes the welding gun to rotate around the welding point. This allows for comprehensive circumferential welding of the two sets of steel while adapting to the included angle, significantly improving the welding efficiency of the steel support.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] For examples, please refer to Figures 1 to 9 The present invention provides a welding device for processing steel supports, the technical solution of which is as follows:

[0035] A welding device for processing steel supports includes a support base 1 and two sets of movable carrier plates 6 disposed on the upper side of the support base 1. A rotating disk 11 is disposed on the upper side of the movable carrier plate 6. A first rotating shaft 13 is fixedly connected to the lower middle of the rotating disk 11, and a movable ring plate 14 is fixedly connected to the lower edge of the rotating disk 11. Several sets of locking holes 16 are opened through the movable ring plate 14. A second fastening bolt 15 is opened through one side of the movable carrier plate 6. A middle groove 2 is opened in the middle of the support base 1. A docking motor 3 is fixedly installed inside the middle groove 2.

An outer locking plate 8 is fixedly connected to one side of the movable carrier plate 6. A first fastening bolt 9 is opened through the outer locking plate 8.

[0036] The upper middle of the movable carrier plate 6 is fixedly embedded with a first rotary motor 12, and the first rotating shaft 13 is fixedly connected to the output end of the first rotary motor 12. The upper edge of the movable carrier plate 6 is provided with an annular groove 17, and the movable ring plate 14 is located inside the annular groove 17. Several sets of locking holes 16 are evenly distributed on the movable ring plate 14, and the second fastening bolt 15 passes through the movable carrier plate 6 and engages with the movable ring plate 14 through the locking holes 16.

[0037] Two sets of movable carrier plates 6 are symmetrically arranged about the intermediate groove 2. The first sliding block 5 is fixedly connected to the movable carrier plate 6.

Several sets of external locking grooves 10 are provided on one side of the bearing base 1, and the first fastening bolt 9 passes through the external locking plate 8 and engages with the bearing base 1 in the external locking groove 10.

[0038] Specifically, by activating the first rotary motor 12 on the movable carrier plate 6, the first rotating shaft 13 is rotated, which in turn drives the rotating disk 11 to rotate under the cooperation of the movable ring plate 14 and the annular groove 17. This causes the two sets of steel to rotate relative to each other until the angle between the two sets of steel is consistent with the target angle. The second fastening bolt 15 and the locking hole 16 are then engaged to fix the position of the rotating disk 11. Next, the docking motor 3 on the bearing base 1 is activated, which drives the two sets of first lead screw shafts 4 to rotate together. Under the cooperation of the symmetrical external threads, the two sets of first sliding blocks 5 move relative to each other along the two sets of sliding grooves 7, which in turn drives the two sets of movable carrier plates 6 to move relative to each other until the welded parts of the two sets of steel are in contact. The first fastening bolt 9 is then passed through the outer locking plate 8 and engaged with the outer locking groove 10. This allows the two sets of steel to be welded at a specified angle according to actual needs, with a wide range of applications and significantly improved welding flexibility.

[0039] A first threaded rod 19 is provided through the center of the rotating disk 11. Two sets of first moving blocks 20 are sleeved on the first threaded rod 19.

[0040] Both ends of the first threaded rod 19 are fixedly connected to the first rotating handle 18, and both sets of the first rotating handle 18 are located on the outside of the rotating disk 11. The first threaded rod 19 is provided with symmetrical threaded sections, and the first moving block 20 is threadedly connected to the first threaded rod 19.

The second threaded rod 27 is provided with symmetrical threaded sections. The second moving block 28 passes through the limiting plate 21 and is threadedly connected to the second threaded rod 27. The second moving block 28 is located inside the vertical groove body 25. The second limiting bolt 31 is threadedly connected to the second limiting plate 30, and the second limiting bolt 31 cooperates with the second rotating handle 26.

[0042] Specifically, by rotating the first rotating handle 18, the first threaded rod 19 is rotated, thereby driving the two sets of first moving blocks 20 to move relative to each other along the limiting groove 22 under the cooperation of the symmetrical threaded sections. This, in turn, drives the two sets of limiting plates 21 to move relative to each other until both sets of limiting plates 21 are in contact with the steel. The first limiting bolt 24 and the first limiting plate 23 are connected by threads to ensure that the first limiting bolt 24 is in close contact with the first rotating handle 18. Then, by rotating the second rotating handle 26, the second threaded rod 27 is rotated, thereby driving the two sets of second moving blocks 28 to move relative to each other along the vertical groove 25 under the cooperation of the symmetrical threaded sections. This, in turn, drives the two sets of limiting bars 29 to move relative to each other until all four sets of limiting bars 29 are in contact with the steel. The second limiting bolt 31 and the second limiting plate 30 are connected by threads to ensure that the second limiting bolt 31 is in close contact with the second rotating handle 26. This method is suitable for positioning two sets of steel of different sizes and ensures the welding stability of the two sets of steel.

[0043] A support rod 32 is fixedly connected to the middle of one side of the support base 1. A transverse groove 33 is fixedly connected to the top of the support rod 32. A second lead screw shaft 35 is inserted through the transverse groove 33. A second sliding block 36 is sleeved on the second lead screw shaft 35. A positioning bolt 37 is inserted through the upper part of the second sliding block 36. A moving ring 38 is fixedly connected to the bottom of the second sliding block 36. A fixing plate 39 is fixedly connected to the moving ring 38. A second rotating shaft 41 is inserted through the fixing plate 39. A rotating gear 42 is fixedly connected to the end of the second rotating shaft 41. A serrated ring 43 is provided on the inner side of the moving ring 38. A welding gun 44 is fixedly connected to one side of the serrated ring 43. A limit slip ring 45 is fixedly sleeved on the outer side of the moving ring 38.

[0044] The support link 32 is L-shaped. The transverse groove 33 is located on the upper side of the limiting plate 21. The outer end of the transverse groove 33 is fixedly installed with a translation motor 34, and the second lead screw shaft 35 is fixedly connected to the output end of the translation motor 34. The second sliding block 36 is threadedly connected to the second lead screw shaft 35. The second sliding block 36 is located on the inner side of the transverse groove 33. The positioning bolt 37 passes through the lower side of the second sliding block 36 and cooperates with the second lead screw shaft 35.

[0045] The movable ring 38 is located on the upper side of the rotating disk 11. The second rotary motor 40 is fixedly installed on the outer side of the fixed plate 39, and the second rotating shaft 41 is fixedly connected to the output end of the second rotary motor 40. The rotating gear 42 is located inside the movable ring 38, and the rotating gear 42 meshes with the sawtooth ring 43. The inner wall of the movable ring 38 is provided with a movable groove 46, and the limiting slip ring 45 is located inside the movable groove 46.

[0046] Specifically, by activating the translation motor 34 at the end of the transverse groove 33, the second lead screw shaft 35 is rotated. This, through the threaded connection between the second lead screw shaft 35 and the second sliding block 36, moves the second sliding block 36 along the transverse groove 33, thereby causing the moving ring 38 to translate until the welding point of the two sets of steel is located at the center of the moving ring 38. The second lead screw shaft 35 is then fixed by the positioning bolt 37. Next, the second rotary motor 40 on the outside of the fixing plate 39 is activated, causing the second rotating shaft 41 and the rotating gear 42 to rotate together. This, through the meshing rotating gear 42 and the serrated ring 43, in conjunction with the limiting slip ring 45 and the movable groove 46, causes the serrated ring 43 to rotate, thereby causing the welding gun 44 to rotate around the welding point. This allows for comprehensive circumferential welding of the two sets of steel while adapting to the included angle, significantly improving the welding efficiency of the steel support.

[0047] Working principle: First, the operator rotates the first rotating handle 18 to rotate the first threaded rod 19, thereby causing the two sets of first moving blocks 20 to move relative to each other along the limiting groove 22 under the cooperation of the symmetrical threaded sections. This, in turn, causes the two sets of limiting plates 21 to move relative to each other until both sets of limiting plates 21 are in contact with the steel. The threaded connection between the first limiting bolt 24 and the first limiting plate 23 ensures that the first limiting bolt 24 is tightly fitted with the first rotating handle 18. Next, the operator rotates the second rotating handle 26 to rotate the second threaded rod 27, thereby causing the two sets of second moving blocks 28 to move relative to each other along the vertical groove 25 under the cooperation of the symmetrical threaded sections. This, in turn, causes the two sets of limiting bars 29 to move relative to each other. The process continues until all four sets of limiting bars 29 are in contact with the steel, and the second limiting bolt 31 and the second limiting plate 30 are threaded together to ensure that the second limiting bolt 31 and the second rotating handle 26 are tightly fitted together. This is suitable for positioning two sets of steel of different sizes and ensures the welding stability of the two sets of steel. Next, the first rotating motor 12 on the moving carrier plate 6 is started to drive the first rotating shaft 13 to rotate, thereby driving the rotating disk 11 to rotate under the cooperation of the movable ring plate 14 and the annular groove 17, thereby driving the two sets of steel to rotate relative to each other until the angle between the two sets of steel is consistent with the target angle. Then, the second fastening bolt 15 and the locking hole 16 are engaged to fix the position of the rotating disk 11. The docking motor 3 on the bearing base 1 is started to drive the two sets of first lead screw shafts 4 to rotate together. This, in conjunction with the symmetrical external threads, causes the two sets of first sliding blocks 5 to move relative to each other along the two sets of sliding grooves 7, thereby causing the two sets of moving carrier plates 6 to move relative to each other until the welded parts of the two sets of steel materials come into contact. The first fastening bolt 9 passes through the outer clamping plate 8 and engages with the outer clamping groove 10. This allows the two sets of steel materials to be welded at a specified angle according to actual needs, offering a wide range of applications and significantly improving welding flexibility. Finally, the translation motor 34 at the end of the transverse groove 33 is started to drive the second lead screw shaft 35 to rotate. This, through the threaded connection between the second lead screw shaft 35 and the second sliding block 36, drives the second sliding block... Block 36 moves along the transverse groove 33, thereby driving the moving ring 38 to translate until the welding point of the two sets of steel is located at the center of the moving ring 38. The second lead screw shaft 35 is fixed by the positioning bolt 37. Then, the second rotary motor 40 on the outside of the fixing plate 39 is started to drive the second rotating shaft 41 and the rotating gear 42 to rotate together. The meshing rotating gear 42 and the serrated ring 43, together with the limiting slip ring 45 and the movable groove 46, drive the serrated ring 43 to rotate, thereby driving the welding gun 44 to rotate around the welding point. It can realize the full-circle welding function of the two sets of steel while adapting to the included angle of the two sets of steel, which significantly improves the welding efficiency of the steel bracket and completes the operation.
