Description

Technical Field

[0001] This utility model relates to the technical field of welding, specifically to a bevel welding device for polygonal steel columns. Background Technology

[0002] Steel structures have good ductility, plasticity, and toughness, and excellent seismic resistance and load-bearing capacity, which can improve the safety and reliability of buildings. Therefore, in the field of steel structure engineering, steel column welding is a key process to achieve high-strength and rigid connection of components.

[0003] For example, Chinese utility model patent publication number CN211735758U discloses a steel column splicing node, which includes: an upper column and a lower column, which are steel pipe columns, with a bevel at the lower end of the upper column or the upper end of the lower column; at least two embedded steel plates, one side of which is disposed on the inner wall of the lower end of the upper column or the upper end of the lower column; the lower end of the upper column and the upper end of the lower column are joined together, and the upper and lower columns are welded into a single structure through the bevel. This utility model's steel column splicing node allows for the rapid assembly of steel columns on-site without the need for bolts or other fixing methods.

[0004] Because steel columns are generally large in size, they are not easy to move during the welding process, which makes it difficult to quickly align the bevels and thus reduces the welding efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a polygonal steel column bevel welding device that allows for angle adjustment of the steel column before welding, facilitates the adjustment of the steel column bevel, improves the accuracy of steel column welding, and enhances practicality.

[0006] This utility model discloses a polygonal steel column bevel welding device, including a workbench. Multiple limiting mechanisms are fixedly and symmetrically installed on the top of the workbench, and a conveying mechanism is provided at the top of the workbench. Each limiting mechanism includes a supporting screw, which is fixedly installed on the top of the workbench. Slide plates are slidably installed at both ends of the outer sidewall of the supporting screw. Two rotating plates are symmetrically and rotatably installed on the outer sidewall of the slide plates. A first rotating roller is rotatably installed at the other end of the two rotating plates. A fixed platform is fixedly installed between the two supporting screws via two brackets. A longitudinally penetrating groove is formed in the middle region of the fixed platform. A slider is slidably installed on the inner sidewall of the groove. A first screw is screwed into the middle region of the slider, and a clamping plate is rotatably installed at the bottom end of the first screw.

[0007] The outer wall of the slider is slidably connected to the outer wall of the fixed platform via a sliding mechanism. This polygonal steel column beveling welding device operates by sliding the slide plate on the support screw, which simultaneously drives the rotating plate and the first rotating roller to move at an angle. This moves the first rotating roller on one side to the top of the worktable, moving the steel column to the top of the worktable. While rotating the first screw, the clamping plate is simultaneously driven to fit tightly against the surface of the steel column. The slider slides on the groove opened on the fixed platform, which simultaneously drives the first screw and the clamping plate to move the steel column. The slide plate slides on the outer wall of the support screw, which simultaneously drives the rotating plate and the first rotating roller to move at an angle. The first rotating roller fits tightly against the outer wall of the steel column, thus completing the adjustment of the steel column at the top of the worktable. This allows for angle adjustment of the steel column before welding, facilitating the adjustment of the steel column beveling, improving the accuracy of steel column welding, and enhancing practicality.

[0008] Preferably, the sliding mechanism includes a first limiting plate, which is fixedly installed on the outer side wall of the slider. The top end of the first limiting plate is slidably connected to the bottom end of the fixed platform. A second limiting plate is fixedly installed on the outer side wall of the slider, and the bottom end of the second limiting plate is slidably connected to the top end of the fixed platform. When the slider slides on the groove opened on the fixed platform, it simultaneously drives the first limiting plate and the second limiting plate to slide on the outer side wall of the fixed platform, thereby supporting and limiting the outer side wall of the slider.

[0009] Preferably, the conveying mechanism includes two support plates, which are symmetrically fixedly installed on the top of the workbench. Multiple rotating shafts are installed parallel to and rotatably between the two support plates. A conveying roller is fixedly installed on the outer wall of each rotating shaft. The outer wall of each conveying roller is in contact with the outer wall of each first rotating roller. The steel column is moved to the outer wall of each conveying roller. After contacting the steel column through the clamping plate, it slides on the slide groove opened on the fixed table through the slider, thereby synchronously driving the steel column to move on the outer wall of each conveying roller.

[0010] Preferably, a support plate is screwed onto the outer wall of each support screw, and the top of each support plate is attached to the bottom of each corresponding slide plate. By rotating the support plate, the slide plate is moved synchronously on the support screw, which in turn drives the rotating plate and the first rotating roller to adjust their height, thereby supporting the slide plate on the support screw.

[0011] Preferably, a clamping plate is screwed onto the outer wall of the support screw, and a rotating disk is fixedly installed on the outer wall of the clamping plate. By rotating the rotating disk, the clamping plate is simultaneously rotated. The rotating clamping plate is in contact with the top of the slide plate, thereby limiting the top of the slide plate that is sliding on the support screw.

[0012] Preferably, the top of the fixed platform has two symmetrically arranged limiting grooves, and the bottom of the second limiting plate has two symmetrically rolled balls. Each ball is rolledly connected to the two limiting grooves respectively. When the second limiting plate drives the slider to slide on the sliding groove, the ball rolls on the limiting groove, which facilitates the second limiting plate to drive the slider to move quickly on the fixed platform.

[0013] Preferably, two connecting grooves are symmetrically formed on the inner sidewall of each of the slide plates. The connecting grooves on each slide plate can prevent the inner sidewall of the slide plate from being isolated from the outer sidewall of the support screw which has threads.

[0014] Preferably, each of the first rotating rollers in this patent can move and fit against the outer wall of the conveying roller, so that when the steel column moves to the top of the conveying roller, the steel column is lowered to the outer wall of each conveying roller on both sides of the fixed platform, which facilitates the support operation of the steel column.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This polygonal steel column bevel welding device operates by sliding a sliding plate on a supporting screw, thereby synchronously driving the rotating plate and the first rotating roller to move at an angle. This moves one side of the first rotating roller to the top of the worktable, moving the steel column to the top of the worktable. While rotating the first screw, it simultaneously drives the clamping plate to fit tightly against the surface of the steel column. The sliding block slides on the groove opened on the fixed table, thereby synchronously driving the first screw and the clamping plate to move the steel column. The sliding plate slides on the outer wall of the supporting screw, thereby synchronously driving the rotating plate and the first rotating roller to move at an angle. The first rotating roller fits tightly against the outer wall of the steel column, thereby completing the adjustment of the steel column at the top of the worktable. This allows for angle adjustment of the steel column before welding, facilitating the adjustment of the steel column bevel, improving the accuracy of steel column welding, and enhancing practicality.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] This utility model discloses a polygonal steel column bevel welding device, including a workbench 1. Multiple limiting mechanisms are fixedly installed parallel and symmetrically on the top of the workbench 1, and a conveying mechanism is provided on the top of the workbench 1. The limiting mechanism includes a support screw 2, which is fixedly installed on the top of the workbench 1. Slide plates 3 are slidably installed on both ends of the outer side wall of the support screw 2. Two rotating plates 4 are symmetrically rotated on the outer side wall of the slide plates 3. A first rotating roller 5 is rotatably installed on the other end of the two rotating plates 4. A fixed platform 7 is fixedly installed between the two support screws 2 through two brackets 6. A groove 8 is longitudinally opened through the middle area of ​​the fixed platform 7. A slider 9 is slidably installed on the inner side wall of the groove 8. A first screw 10 is screwed into the middle area of ​​the slider 9. A clamping plate 11 is rotatably installed at the bottom end of the first screw 10.

[0023] The outer wall of slider 9 is slidably connected to the outer wall of fixed platform 7 via a sliding mechanism. The sliding mechanism includes a first limiting plate 12, which is fixedly installed on the outer wall of slider 9. The top end of the first limiting plate 12 is slidably connected to the bottom end of fixed platform 7. A second limiting plate 13 is fixedly installed on the outer wall of slider 9, and the bottom end of the second limiting plate 13 is slidably connected to the top end of fixed platform 7. The conveying mechanism includes two support plates 14, which are symmetrically fixedly installed on the top of worktable 1. Multiple rotating shafts 15 are parallel and rotatably installed between the two support plates 14. A conveying roller 16 is fixedly installed on the outer wall of each rotating shaft 15. The outer wall of each conveying roller 16 is in contact with the outer wall of each first rotating roller 5. Each support screw... Each of the outer walls of the support screw 2 is screwed with a support plate 17, the top of each support plate 17 is attached to the bottom of each corresponding slide plate 3. A clamping plate 18 is screwed on the outer wall of the support screw 2, and a rotating disk 19 is fixedly installed on the outer wall of the clamping plate 18. Two limiting grooves 21 are symmetrically opened at the top of the fixed platform 7. Two rolling balls 20 are symmetrically rolled at the bottom of the second limiting plate 13. Each rolling ball 20 is rolledly connected to the two limiting grooves 21. Two connecting grooves 22 are symmetrically opened on the inner wall of each slide plate 3. Each first rotating roller 5 in this patent can move and operate against the outer wall of the conveying roller 16. When the steel column moves to the top of the conveying roller 16, the steel column will descend to the outer wall of each conveying roller 16 on both sides of the fixed platform 7.

[0024] like Figures 1 to 4As shown, this utility model discloses a polygonal steel column beveling welding device. During operation, the sliding plate 3 slides on the supporting screw 2, simultaneously driving the rotating plate 4 and the first rotating roller 5 to move at different angles. Simultaneously, the rotating support plate 17 drives the sliding plate 3 to move on the supporting screw 2, thereby simultaneously adjusting the height of the rotating plate 4 and the first rotating roller 5. This supports the sliding plate 3 on the supporting screw 2, allowing one side of the first rotating roller 5 to move to the worktable. At the top of the worktable 1, the steel column is moved to the outer wall of each conveyor roller 16. After contacting the steel column via the clamping plate 11, the slider 9 slides on the groove 8 opened on the fixed table 7. When the second limiting plate 13 drives the slider 9 to slide on the groove 8, the ball 20 rolls on the limiting groove 21, which facilitates the second limiting plate 13 to drive the slider 9 to move quickly on the fixed table 7, and synchronously drives the steel column to move on the outer wall of each conveyor roller 16, moving the steel column to the top of the worktable 1. At the end, rotating the first screw 10 simultaneously causes the clamping plate 11 to fit tightly against the surface of the steel column. The slider 9 slides on the groove 8 on the fixed platform 7. As the slider 9 slides on the groove 8, it simultaneously causes the first limiting plate 12 and the second limiting plate 13 to slide on the outer wall of the fixed platform 7, thus supporting and limiting the outer wall of the sliding slider 9. This, in turn, simultaneously drives the first screw 10 and the clamping plate 11 to move the steel column. The sliding plate 3 supports the screw... The sliding operation on the outer wall of the 2 is carried out simultaneously by rotating the rotating disk 19 and driving the clamping plate 18 to rotate. The clamping plate 18, which rotates, is in contact with the top of the slide plate 3, thereby limiting the top of the slide plate 3, which is sliding on the support screw 2. This, in turn, drives the rotating plate 4 and the first rotating roller 5 to move in angle. The first rotating roller 5 is in close contact with the outer wall of the steel column, thereby completing the adjustment of the steel column at the top of the workbench 1, and thus allowing the steel column to be adjusted in angle before welding.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
