Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and particularly to a welding device for building steel structures. Background Art

[0002] In the construction field, steel structures are widely used due to their advantages such as high strength, light weight, and fast construction speed.

Detailed implementation manners

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] As Figures 1 to 5 shown, a building steel structure welding device proposed by the present invention includes a frame, and further includes a crossbeam fastening module 1 and a vertical beam fastening module 2 installed on the frame. A crossbeam 3 is fixed on the crossbeam fastening module 1, and a vertical beam 4 is fastened on the vertical beam fastening module 2. The crossbeam fastening module 1 and the vertical beam fastening module 2 respectively fix and position the crossbeam 3 and the vertical beam 4, and keep the crossbeam 3 and the vertical beam 4 perpendicular. When welding the crossbeam 3 and the vertical beam 4, first, it is necessary to position the crossbeam 3 and the vertical beam 4. Generally, the center of gravity of the vertical beam 4 is aligned with the center of the crossbeam 3, and then fixed, and then welding can be carried out.

[0019] Further, the crossbeam fastening module 1 includes a support plate 101 fixedly installed on the frame. Clamping components are slidably installed on both sides of the support plate 101. The clamping component includes a pressure rod 102 slidably installed on the support plate 101. A pressure block 103 is fixedly installed on the pressure rod 102. A transmission rod 104 is rotatably installed on the pressure rod 102. The two transmission rods 104 are rotatably connected through a synchronous block 105. A cross plate 106 is fixedly installed between the two synchronous blocks 105. A first push rod motor 107 is fixedly installed on the support plate 101. The output shaft of the first push rod motor 107 is fixedly connected to the cross plate 106. By means of the first push rod motor 107, the synchronous blocks 105 on both sides can be driven to move synchronously. The moving synchronous blocks 105 will drive the pressure rods 102 to move through the transmission rods 104, so that the pressure rods 102 on both sides move synchronously, driving the pressure blocks 103 on both sides to approach or move away from each other. Thus, the crossbeam 3 located on the support plate 101 can be pushed to move, aligning the center of the crossbeam 3 with the support plate 101 and pressing and fixing it.

[0020] Still further, the vertical beam fastening module 2 includes multiple optical axes 201 fixedly installed on the frame. A driving ring 202 is slidably installed on the multiple optical axes 201. A support ring 203 is fixedly installed on the frame. Multiple guide rods 204 are fixedly installed on the support ring 203. A push rod 205 is slidably installed on the guide rods 204. One end of the push rod 205 is fixedly installed with a push block 206. The other end of the push rod 205 is rotatably installed with a driving strip 207. The other end of the driving strip 207 is rotatably connected to the driving ring 202. A second push rod motor 208 is fixedly installed on the frame. The output shaft of the second push rod motor 208 is fixedly connected to the driving ring 202. When installing and positioning the vertical beam 4, the vertical beam is placed above the crossbeam 3, and the second push rod motor 208 is started to drive the driving ring 202 to move along the optical axes 201. The moving driving ring 202 will drive the driving strip 207 to rotate. The rotating driving strip 207 can push the push rod 205 to move. The four push blocks 206 respectively correspond to the four faces of the vertical beam 4, enabling the push blocks 206 to fit on the vertical beam 4. Thus, the center of the vertical beam 4 can be aligned with the center of the crossbeam 3, and the vertical beam 4 can be fixed.

[0021] It should be noted that when installing the vertical beam 4, the vertical beam 4 needs to be lifted and placed inside the driving ring 202 and the support ring 203. By providing notches on both the driving ring 202 and the support ring 203, the vertical beam 4 can enter the inside of the driving ring 202 and the support ring 203 through the notches, preventing the need to lift the vertical beam 4 to a relatively high position and insert it into the inside of the driving ring 202 and the support ring 203 from a high place. Thus, the manpower and material resources consumed during the installation of the vertical beam 4 can be reduced.

[0022] Such as Figures 6 to 9As shown in the figure, this embodiment further includes a welding guiding mechanism 5. A welding gun 6 is installed on the welding guiding mechanism 5. The welding guiding mechanism 5 guides the moving path of the welding gun 6 and provides circular and rectangular paths of different sizes for the welding gun 6, so as to adapt to square steel pipes and circular steel pipes of different sizes, greatly improving the applicability of the welding device.

[0023] Furthermore, the welding guiding mechanism 5 includes a circular guiding disk 501 fixedly installed on the frame. A guiding block 502 is slidably installed in the guiding disk 501. An extendable rod member 503 with adjustable length is fixedly installed on the guiding block 502. A connecting seat 504 is fixedly installed on the extendable rod member 503. The welding gun 6 is rotatably connected to the connecting seat 504. A lever 512 is fixedly installed on the guiding block 502. By pulling the lever 512, the guiding block 502 can be driven to move inside the guiding disk 501, thereby driving the welding gun 6 to move circularly. By adjusting the length of the extendable rod member 503, circular steel pipes of different diameters can be adapted. A damping should be provided at the rotational connection between the welding gun 6 and the connecting seat 504 to facilitate the adjustment of the angle of the welding gun 6.

[0024] Among them, the extendable rod member 503 includes a connecting sleeve 5031 fixedly installed on the guiding block 502. A sliding rod 5032 is slidably installed in the connecting sleeve 5031. The sliding rod 5032 is fixedly connected to the connecting seat 504. A kidney-shaped hole 5033 is provided on the connecting sleeve 5031. A threaded groove 5034 is provided in the sliding rod 5032. A bolt 5035 is threadedly connected in the threaded groove 5034. A rubber pad 5036 is sleeved on the bolt 5035. By sliding the sliding rod 5032 inside the connecting sleeve 5031, the total length of the extendable rod member 503 can be changed, and thus the welding gun 6 can be driven to move. When fixing the sliding rod 5032, just rotate the bolt 5035 to press the rubber pad 5036. At this time, the pressure between the sliding rod 5032 and the connecting sleeve 5031 will increase, and the sliding rod 5032 will be fixed under the action of friction.

[0025] Furthermore, the welding guiding mechanism further includes a rotating shaft 505 fixedly installed on the connecting seat 504. Here, the rotating shaft 505 needs to be set as a detachable connection structure. When using a rectangular trajectory, the rotating shaft 505 is fixedly connected to the connecting seat 504. Otherwise, the rotating shaft 505 needs to be disassembled. Four sets of frame plate members that are interconnected to form a rectangle are installed on the frame. The frame plate members include a support shaft 506 with adjustable length fixedly installed on the frame, and a base 507 fixedly installed on the support shaft 506. Extension seats 508 are slidably installed at both ends of the base 507. A connecting block 509 is slidably installed in one of the bases 507. The rotating shaft 505 is rotatably connected to the connecting block 509. When using a rectangular path, the bolt 5035 needs to be loosened to make the telescopic member 503 freely expand and contract. At this time, when the telescopic member 503 rotates along the guiding disk 501, it will perform telescopic movement under the action of the frame plate members, and the connecting seat 504 will move according to the path of the frame plate members, thereby driving the welding gun 6 to move along a specified path. This can enable the welding gun 6 to quickly and accurately weld the square steel pipe, and the length of the support shaft 506 can be adjusted according to the size of the square steel pipe. The length adjustment method of the support shaft 506 is prior art and will not be elaborated here. A steering component for driving the rotating shaft 505 to rotate at the corner is installed on the frame plate members, which can enable the welding gun 6 to always face the position where the square steel pipe needs to be welded.

[0026] In this embodiment, the steering component includes a gear 510 fixedly installed on the rotating shaft 505. Arc-shaped racks 511 are fixedly installed at the four corners of the frame plate members. The arc-shaped racks 511 are meshed with the gear 510. The teeth on the arc-shaped racks 511 are one-fourth of the teeth of the gear 510. When the welding gun 6 rotates to the corner of the frame plate members, the gear 510 meshes with the arc-shaped rack 511 and drives the gear 510 to rotate, and the rotation angle is 90°. Furthermore, the welding gun 6 can always face the position where welding is required. During welding, the total length of the base 507 and the extension seat 508 can be made greater than the length of the square steel pipe, so that after one side is welded and the welding gun 6 leaves the welding position, it can rotate.

[0027] It should be noted that since the base 507 and the extension base 508 are slidably connected, there will be a certain height difference at the junction of the base 507 and the extension base 508, which is likely to cause the connecting block 509 to jam and operate unstably, resulting in an unstable movement path of the welding gun 6. By slidably installing support shafts 5091 on both sides of the connecting block 509, rollers 5092 are rotatably installed on the support shafts 5091, and a linkage assembly for driving the two rollers 5092 to move synchronously and equidistantly is installed in the connecting block 509. The linkage assembly includes a connecting rod 5093 rotatably installed on the support shaft 5091. A linkage block 5094 is slidably installed in the connecting block 509 through a telescopic shaft 5095. A spring 5096 is fixedly installed between the linkage block 5094 and the connecting block 509. Under the action of the spring 5096, the rollers 5092 always abut against the inner wall of the base 507 or the extension base 508, and the two rollers 5092 can move synchronously, so that the rollers 5092 can smoothly pass through the junction of the base 507 and the extension base 508 and ensure the stable operation of the connecting block 509, thereby ensuring the stability of the welding gun 6.

[0028] In this embodiment, when welding the cross beam 3 and the vertical beam 4, first, the cross beam 3 and the vertical beam 4 need to be positioned. Generally, the center of gravity of the vertical beam 4 is aligned with the center of the cross beam 3, and then fixed, and then welding can be carried out; When welding a circular steel pipe, after removing the rotating shaft 505, pulling the lever 512 can drive the guide block 502 to move inside the guide disk 501, thereby driving the welding gun 6 to move circularly, and by adjusting the length of the telescopic member 503, circular steel pipes of different diameters can be adapted; When welding a steel pipe, the rotating shaft 505 is fixedly connected to the connecting seat 504, and the bolt 5035 is loosened to make the telescopic member 503 freely expand and contract. At this time, when the telescopic member 503 rotates along the guide disk 501, it will expand and contract under the action of the frame plate member, and the connecting seat 504 will move according to the path of the frame plate member, thereby driving the welding gun 6 to move along a specified path, enabling the welding gun 6 to quickly and accurately weld the square steel pipe, and the length of the support shaft 506 can be adjusted according to the size of the square steel pipe to meet the requirements of welding various steel pipes of different sizes.

[0029] The above specific embodiments are only several alternative embodiments of the present invention.
