[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] It should be noted that when a component is referred to as being "mounted to," "fixed to," or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0037] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] like Figures 1 to 7 As shown, this application provides a welding device for prefabricated steel structures, including a positioning mechanism 1, a driving mechanism 2, and multiple welding mechanisms 3. The positioning mechanism 1 includes a positioning plate 11, a fixed shaft 12, multiple adjusting components 13, and multiple positioning components 14. The fixed shaft 12 is connected to the positioning plate 11. The multiple adjusting components 13 are all mounted on the positioning plate 11, and the multiple positioning components 14 are respectively mounted on the multiple adjusting components 13 and configured to move under the drive of the multiple adjusting components 13. It is also configured to use multiple screw holes 6 to make the axis of the fixed shaft 12 coincide with the axis of the column 4. The driving mechanism 2 includes a driving component 21 and a rotating bracket 22. The driving component 21 is mounted on the positioning plate 11, and the rotating bracket 22 is mounted on the fixed shaft 12 and rotates under the drive of the driving component 21. The multiple welding mechanisms 3 are all mounted on the rotating bracket 22. The welding mechanism 3 includes a first driver 31, a second driver 32, a third driver 33, and a welder 34. The first driver 31 is mounted on the rotating bracket 22 and rotates with the rotating bracket 22 around the axis of the column 4. The second driver 32 is mounted on the output end of the first driver 31 and moves radially along the column 4 under the drive of the first driver 31. The third driver 33 is mounted on the output end of the second driver 32 and moves axially under the drive of the second driver 32. The welder 34 is mounted on the output end of the third driver 33 and rotates under the drive of the third driver 33.

[0040] It should be noted that the "above" and "below" axes refer to the bidirectional direction of the central axis defined by the structure of column 4 itself, specifically as follows: Figure 2 The X-axis is shown in the figure.

[0041] It should also be noted that in this embodiment, the cross-sectional shape of the column 4 is set to a circle as an example.

[0042] This application provides a prefabricated steel structure welding device. When welding multiple reinforcing plates 7, multiple positioning components 14 position the positioning plate 11 and the fixed shaft 12 through multiple screw holes 6, so that the axis of the fixed shaft 12 coincides with the axis of the column 4. This allows the rotation axis of the rotating bracket 22 to coincide with the axis of the column 4, enabling the welder 34 to rotate around the axis of the column 4. Since the multiple reinforcing plates 7 are evenly arranged circumferentially around the axis of the column 4, there is no need to repeatedly adjust the position of the welder 34 in the circumferential direction, greatly improving welding efficiency. Furthermore, using the screw holes 6 of the steel structure for positioning, so that the axis of the fixed shaft 12 coincides with the axis of the column 4, can effectively improve welding accuracy and welding quality. Under the action of the third actuator 33, the welder 34 can be driven to rotate relative to the reinforcing plate 7, so that the welder 34 can always be directly facing the gap between the reinforcing plate 7 and the column 4, which helps to improve the welding quality of the welder 34. Under the action of the first actuator 31, the position of the welder 34 in the radial direction of the column 4 can be adjusted. Under the action of the second actuator 32, the position of the welder 34 in the axial direction of the column 4 can be adjusted. Under the action of the first actuator 31 and the second actuator 32, the welder 34 can be used to weld columns 4 of different sizes and reinforcing plates 7 of different sizes, greatly improving its applicability. Under the combined action of the drive assembly 21, the rotating bracket 22, the first actuator 31, the second actuator 32 and the third actuator 33, the welder 34 can automatically weld multiple reinforcing plates 7 between the column 4 and the base plate 5, with a high degree of automation. Compared with the prior art, it effectively reduces labor intensity and has high welding efficiency. Furthermore, multiple welding mechanisms 3 are provided, which can be welded synchronously under the drive of the rotating bracket 22, which helps to further improve welding efficiency compared to having only one welding mechanism 3.

[0043] Optionally, the first driver 31 and the second driver 32 are both electric cylinders, and the third driver 33 is a rotary motor.

[0044] In one embodiment of this application, please refer to Figures 1 to 7The positioning plate 11 includes a plate body 111 and multiple clearance grooves 112. Each clearance groove 112 is formed in the plate body 111 and corresponds to one of the multiple adjustment components 13. Each adjustment component 13 includes two first adjustment members 131 and a second adjustment member 132. The two first adjustment members 131 are mounted on the plate body 111, and the second adjustment member 132 is mounted between the two first adjustment members 131 and moves radially under the influence of the two first adjustment members 131. It is also configured to drive the positioning component 14 to move chordally.

[0045] It should be noted that the chord direction above and below refers to the bidirectional direction of the shortest line connecting any two points on the circumference.

[0046] With this configuration, the radial position of the positioning component 14 can be adjusted by the first adjusting member 131. The chordal position of the positioning component 14 can be adjusted by the second adjusting member 132. The combined action of the first and second adjusting members 131 and 132 allows the position of the positioning component 14 to be adjusted from two different directions, ensuring that the positioning component 14 can always pass through the screw hole 6, greatly improving the applicability of the positioning mechanism 1. The multiple clearance slots 112 allow for the clearance of multiple positioning components 14, preventing the plate 111 from interfering with the positioning component 14 and causing it to be unable to pass through the screw hole 6.

[0047] In one embodiment of this application, please refer to the following: Figures 1 to 7 The first adjusting component 131 includes a fixed base 1311, a slide groove 1312, a fixed block 1313, a slider 1314, and an adjusting bolt 1315. The fixed base 1311 is connected to the plate 111. The slide groove 1312 is formed in the fixed base 1311. The fixed block 1313 is installed in the fixed base 1311. The slider 1314 is slidably installed in the two slide grooves 1312. The adjusting bolt 1315 is screwed to the fixed block 1313 and abuts against the slider 1314.

[0048] This configuration allows the slider 1314 to be adjusted within the groove 1312 by the adjusting bolt 1315, thereby facilitating the adjustment of the radial positions of the second adjusting member 132 and the positioning assembly 14. The groove 1312 also limits the slider 1314, ensuring it can only slide radially, thus improving its stability. The fixing block 1313 serves to screw the adjusting bolt 1315 in place and to fix the bolt 1315 to itself, facilitating the movement of the slider 1314. The slider 1314 engages within the groove 1312, preventing it from slipping out of the fixing blocks 1313 when the second adjusting member 132 slides, thus improving the structural stability between the second adjusting member 132 and the fixing blocks 1313. Under the action of adjusting bolt 1315, after the position is adjusted, the fixing block 1313 can achieve self-locking, which can prevent the second adjusting part 132 from moving radially during the welding process.

[0049] In one embodiment of this application, see [reference] Figures 1 to 7 The second adjusting component 132 includes a limiting rod 1321, an adjusting screw 1322, an adjusting block 1323, and a knob 1324. The limiting rod 1321 and the adjusting screw 1322 are both connected between two sliders 1314. The adjusting block 1323 is sleeved on the limiting rod 1321 and the adjusting screw 1322. The knob 1324 is sleeved on the adjusting screw 1322 and is rotatably engaged in the adjusting block 1323.

[0050] With this configuration, the position of the adjusting block 1323 in the chordal direction can be adjusted by the knob 1324 and the adjusting screw 1322, making adjustment convenient. The limiting rod 1321 limits the adjustment block 1323, preventing it from rotating with the knob and ensuring it can only move chordally, i.e., between the two fixed blocks 1313. This improves the stability of the adjustment block 1323's movement and also allows adjustment of the chordal position of the positioning assembly 14. The adjusting screw 1322, in conjunction with the limiting rod 1321, also limits the adjustment block 1323. Furthermore, after position adjustment, it prevents the adjustment block 1323 from moving chordally during welding.

[0051] In one embodiment of this application, please refer to Figures 1 to 7 The positioning component 14 includes a positioning rod 141, a first positioning nut 142, and a second positioning nut 143. The positioning rod 141 passes through the adjustment component 13 and is configured to form a limit with the screw hole 6. The first positioning nut 142 and the second positioning nut 143 are both screwed to the positioning rod 141 and are configured to limit the base plate 5 and the adjustment component 13.

[0052] With this configuration, under the action of the positioning rod 141, it can pass through the screw hole 6, passing through the base plate 5 and the adjusting block 1323, preventing the plate body 111 from rotating relative to the positioning plate 11, thus achieving positioning. Under the action of the first positioning nut 142 and the second positioning nut 143, the positioning pin can be prevented from coming off the base plate 5 and the adjusting block 1323, which helps to improve the structural stability between the base plate 5 and the adjusting block 1323, thereby helping to improve the structural stability between the base plate 5 and the plate body 111.

[0053] In one embodiment of this application, please refer to the following: Figures 1 to 7 The positioning rod 141 includes a first rod body 1411, a second rod body 1412, and a positioning frustum 1413. The first rod body 1411 passes through the screw hole 6 and is used to screw on the first positioning nut 142. The second rod body 1412 passes through the adjusting assembly 13 and is used to screw on the second positioning nut 143. The positioning frustum 1413 connects the first rod body 1411 and the second rod body 1412. The diameter of the first rod body 1411 is smaller than the diameter of the second rod body 1412.

[0054] This configuration, under the action of the positioning frustum 1413, can be used to hold screw holes 6 of different diameters, allowing the positioning rod 141 to fit snugly against screw holes 6 of different diameters, resulting in good fixing effect and improving the applicability of the positioning rod 141. Furthermore, the positioning frustum 1413 can also prevent the second rod 1412 from detaching from the screw hole 6, which also helps to improve the structural stability between the base plate 5 and the plate 111. Under the action of the first rod 1411 and the second rod 1412, they are used to screw the first positioning nut 142 and the second positioning nut 143 respectively, thereby preventing the plate 111 and the adjusting block 1323 from detaching from the positioning rod 141, resulting in good limiting effect.

[0055] In one embodiment of this application, see [reference] Figures 1 to 7 The drive assembly 21 includes a fourth driver 211, a pinion 212 and a large gear 213. The fourth driver 211 is mounted on the positioning plate 11. The pinion 212 is mounted on the output end of the fourth driver 211 and rotates under the drive of the fourth driver 211. The large gear 213 is sleeved on the fixed shaft 12 and meshes with the pinion 212.

[0056] With this configuration, under the action of the pinion 212 and the gear 213, the fourth driver 211 can achieve speed reduction and torque increase, which makes it easier for the fourth driver 211 to drive the rotating bracket 22 to rotate stably and accurately, thereby helping to improve the welding quality of the welder 34.

[0057] Optionally, the fourth driver 211 is configured as a geared motor.

[0058] In one embodiment of this application, please refer to Figures 1 to 7 The rotating support 22 includes a linear bearing 221, an active support 222, a limiting sleeve 223, a connecting frame 224, a driven support 225, and multiple rolling limiting elements 226. The linear bearing 221 is sleeved on the fixed shaft 12 and rotates under the drive of the drive assembly 21. The active support 222 is sleeved on the fixed shaft 12 and installed on the linear bearing 221. The connecting frame 224 is installed on the active support 222. The driven support 225 is installed on the end of the connecting frame 224 away from the active support 222. The multiple rolling limiting elements 226 are all installed on the driven support 225 and abut against the outer periphery of the column 4.

[0059] This configuration, with the linear bearing 221 acting as a guide, helps improve the rotational stability of the active support 222 on the fixed shaft 12, thereby improving the rotational stability of the welder 34. The limiting sleeve 223 prevents the active support 222 from detaching from the fixed shaft 12, contributing to improved structural stability between the active support 222 and the fixed shaft 12. The connecting frame 224 allows the driven support 225 to rotate with the active support 222. The multiple rolling limiting elements 226 limit the rotation of the driven support 225, improving its rotational stability, which in turn contributes to improved rotational stability of the welder 34.

[0060] In one embodiment of this application, please refer to the following: Figures 1 to 7 The rolling limiting component 226 includes a mounting rod 2261, a mounting sleeve 2262, a limiting screw 2263, a roller 2264, and a first limiting nut 2265. The mounting rod 2261 is mounted on the driven bracket 225. The mounting sleeve 2262 is mounted on the end of the mounting rod 2261 away from the driven bracket 225. The limiting screw 2263 passes through the mounting sleeve 2262. The roller 2264 is mounted on the end of the limiting screw 2263 near the column 4. The first limiting nut 2265 is sleeved on the limiting screw 2263 and screwed to it, and is located at the end of the mounting sleeve 2262 facing the roller 2264. The axis of the mounting sleeve 2262 coincides with the diameter of the column 4.

[0061] With this configuration, the mounting rod 2261 can fix the mounting sleeve 2262 to the driven bracket 225, allowing the mounting sleeve 2262, the limiting screw 2263, the roller 2264, and the first limiting nut 2265 to all rotate with the driven bracket 225. The mounting sleeve 2262 limits the limiting screw 2263, ensuring it can only move radially along the column 4, thus improving its stability. Furthermore, by adjusting the radial position of the limiting screw 2263 on the column 4, the roller 2264 can abut against the outer periphery of columns 4 of different diameters, expanding the applicability of the rolling limiting component 226. The first limiting nut 2265 prevents the limiting screw 2263 from dislodging from the mounting sleeve 2262, further improving the structural stability between the limiting screw 2263 and the mounting sleeve 2262.

[0062] In one embodiment of this application, see [reference] Figures 1 to 7 The rolling limiting component 226 also includes a second limiting nut 2266, which is sleeved on the limiting screw 2263 and screwed to the limiting screw 2263, and is located at the end of the mounting sleeve 2262 facing away from the roller 2264.

[0063] With this configuration, the first limiting nut 2265 can also limit the limiting screw 2263 under the action of the second limiting nut 2266, which helps to further improve the structural stability between the limiting screw 2263 and the mounting sleeve 2262.

[0064] The working principle of the prefabricated building steel structure welding device provided in this application is as follows:

[0065] First, during welding, workers initially fix multiple reinforcing plates 7 between the column 4 and the base plate 5 using spot welding. The steel structure is then transported to the welding device provided in this application using an external transport device. Before welding, the positions of multiple positioning components 14 are pre-adjusted using multiple adjusting components 13 according to the diameter of the column 4 and the position of the screw holes 6, so that multiple positioning rods 141 can pass through the screw holes 6. After the multiple positioning rods 141 are positioned, the third actuator 33 drives the welder 34 to rotate, so that the welder 34 is aligned with the gap between the reinforcing plate 7 and the base plate 5, and with the gap between the reinforcing plate 7 and the column 4. The first actuator 31 drives the welder 34 to gradually move away from the column 4, so that the welder 34 welds the gap between the reinforcing plate 7 and the base plate 5, and then the first actuator 31 drives the welder 34 to reset. After resetting, the second actuator 32 drives the welder 34 to gradually move away from the base plate 5 axially, so that the welder 34 welds the gap between the reinforcing plate 7 and the column 4. After welding is completed, the fourth actuator 211 drives the welder 34 to rotate axially around the column 4 until the welder 34 rotates to the side of the reinforcing plate 7 that has not been welded. The third actuator 33 drives the welder 34 to rotate so that the welder 34 is directly facing the gap between the reinforcing plate 7 and the base plate 5, and also directly facing the gap between the reinforcing plate 7 and the column 4. The second actuator 32 drives the welder 34 to move axially towards the base plate 5 so that the welder 34 can weld the gap between the other side of the reinforcing plate 7 and the column 4. After welding is completed, the first actuator 31 drives the welder 34 to move gradually away from the column 4 so that the welder 34 can weld the other gap between the reinforcing plate 7 and the base plate 5, and then the first actuator 31 drives the welder 34 to reset. At this point, all individual reinforcing plates 7 have been welded. Repeat the above steps to weld the remaining reinforcing plates 7.

[0066] In addition, the prefabricated steel structure welding device provided in this application can also weld two columns 4 into one column 4. When welding two columns 4, the welding device 34 is aligned with the gap between the two columns 4, and the fourth actuator 211 drives the welding device 34 to rotate around the axis of the column 4 to complete the welding.

[0067] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
