[0026] Furthermore, a trumpet tube 402 is provided at the end of the robot arm 4 outside the welding gun 401 , and the trumpet tube 402 is connected to the side close to the robot arm 4 and the side away from the robot arm 4 .

[0027] The operating process of this embodiment is: the operating sequence of the welding device of the present invention is as follows: clamp and fix one end of the two steel structures on the two clamping mechanisms 3 respectively - adjust the positions of the two clamping mechanisms 3 according to the lengths of the two steel structures (this step can be repeated) - adjust the angle between the two steel structures after the welding surfaces of the two steel structures are aligned (this step can be repeated) - use the stabilizing splint 2022 and the cross-section alignment sheet 2023 to align the welding surfaces between the two steel structures - use the welding gun 401 on the robotic arm 4 to weld the two steel structures.

[0028] One end of the two steel structures is clamped and fixed on the clamping mechanism 3 respectively, specifically: one end of the steel structure is aligned with the center of the clamping mechanism 3, the fourth servo motor 3023 is started, and the traction circular plate 30231 fixedly connected to the output end of the fourth servo motor 3023 is driven to rotate, and the rotating rail 30233 fixedly connected to one side of the traction circular plate 30231 is rotated and matched between the several support plates 3021, and the rotation of the traction circular plate 30231 drives the traction rod 3032 to slide along the several traction holes 30232 opened on one side of the traction circular plate 30231, and the sliding of the traction rod 3032 drives several limiting plates 3021 to rotate. The positioning blocks 303 slide along the several limiting grooves 30221 opened on one side of the central support plate 3022, driving the clamping plates 3031 fixedly connected at one end of the limiting blocks 303 to move closer to or away from the center of the mounting ring 302 at the same time, thereby clamping and fixing one end of the steel structure. In addition, the inner or outer sides of the several clamping plates 3031 can clamp and fix the inner or outer wall of the steel structure. The steel structure can be clamped on the inner side of the several clamping plates 3031, or the several clamping plates 3031 can be clamped on the inner wall of the steel structure, thereby clamping and fixing the steel structure, making it convenient for the welding gun 401 to perform welding.

[0029] Adjust the positions of the two clamping mechanisms 3 according to the lengths of the two steel structures (this step can be repeated), specifically: start the third servo motor 2052 fixedly installed on the rotating plate 205, drive the second threaded rod 20521 fixedly connected to the output end of the third servo motor 2052 to rotate, and drive the displacement plate 301 that rotates the side threads of the second threaded rod 20521 to move horizontally along the direction of the rotating plate 205 and the second threaded rod 20521. After adjusting the position of the steel structure, turn off the third servo motor 2052, so that the welding surfaces of the two steel structures are aligned, and the welding surfaces of the two steel structures are aligned with the center of the processing table 1, so as to facilitate the alignment of the stabilizing splint 2022 and the cross-section alignment sheet 2023 with the welding surface between the two steel structures.

[0030] After the welding surfaces of the two steel structures are aligned, the angle between the two steel structures is adjusted (this step can be repeated), specifically: start the second servo motor 102 fixedly installed on the processing table 1, and drive the first threaded block 204 fixedly connected to the output end of the second servo motor 102 to move horizontally along the direction of the first threaded rod 1021, wherein the two horizontal moving blocks 2012 fixedly connected to the top of the moving frame 201 slide and fit in the horizontal groove 101 to prevent the moving frame 201 from rotating in the circumferential direction, drive the T-shaped circular rail 2061 to rotate in the positioning sleeve 103, and drive the sliding plate fixedly connected to the top of the T-shaped circular rail 2061 206 rotates around the positioning sleeve 103, driving the sliding plate 206 to move horizontally along the direction of the sliding rods 2051, thereby changing the angle between the two rotating plates 205. When the welding surfaces of the two steel structures are aligned and the welding surfaces of the two steel structures are to be aligned with the center of the processing table 1, the second servo motor 102 is turned off, and the angle between the two steel structures is adjusted by adjusting the angle between the two rotating plates 205, so that the welding surfaces of the two steel structures can be aligned, which facilitates the subsequent use of the stabilizing splint 2022 and the cut surface alignment sheet 2023 to further align the welding surfaces between the two steel structures.

[0031] The above two steps of adjusting the positions of the two clamping mechanisms 3 according to the lengths of the two steel structures and adjusting the angle between the two steel structures after the two steel structure welding surfaces are aligned can be repeated, and are specifically determined according to the degree of alignment of the steel structure welding surfaces in actual applications.

[0032] Use the stabilizing splint 2022 and the cross-section alignment sheet 2023 to align the welding surface between the two steel structures, specifically: start the first servo motor 203 fixedly installed on the mobile frame 201, so that the first gear 2031 fixedly connected to the output end of the first servo motor 203 rotates, driving the meshing racks 202 on both sides of the first gear 2031 to move vertically in opposite directions at the same time, driving the connecting plate 2021 and the stabilizing splint 2022 fixedly connected at the ends of the two racks 202 to move vertically upward or vertically downward, so as to realize the vertical movement of the two stabilizing splints 2022 and the cross-section alignment sheet 2023 fixedly connected to the relative side of the two stabilizing splints 2022 to move closer to or away from each other. The center of the two stabilizing splints 2022 and the center of the two cross-section alignment sheets 2023 are both consistent with the horizontal height of the clamping center of the clamping mechanism 3 by adjusting the distance between the two stabilizing splints 2022. The clamping and fixation of the two steel structure welding ends are achieved. The two cross-section alignment sheets 2023 are also fitted and arranged between the two steel structure welding surfaces, which is beneficial to aligning the welding surfaces of the two steel structures and improving the welding effect of the steel structure. After completing the alignment of the steel structure welding surfaces in this step, the first servo motor 203 should be started in reverse so that the distance between the two stabilizing splints 2022 and the distance between the two cross-section alignment sheets 2023 are gradually increased to prevent affecting subsequent welding.

[0033] Use the welding gun 401 on the robotic arm 4 to weld the two steel structures: start the robotic arm 4, so that the end of the robotic arm 4 drives the welding gun 401 to weld the welding surfaces of the two steel structures. The smoke generated during the welding process is blocked by the trumpet tube 402 and will not splash outward. In addition, the special shape design of the trumpet tube 402 can avoid the influence of poor ventilation on welding during the welding process.

[0034] The above improves the welding effect of the entire device by adjusting the angle between the two rotating plates 205 to adjust the angle between the two steel structures, and aligning the welding surfaces of the two steel structures by adjusting the distance between the two stabilizing splints 2022 and the cross-sectional alignment sheets 2023 fixedly connected to the opposite sides of the two stabilizing splints 2022.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
