[0029] As Figures 1 to 8 , this embodiment discloses a steel structure welding positioning device, including a frame 10. A storage rack 11 is provided at the upper end of the frame 10. A first lifting drive device 12 driven along the z direction is provided inside the frame 10. The output end of the first lifting drive device 12 is connected with a pallet 13. Two positioning assemblies 20 capable of moving along the y direction are provided on the pallet 13. The two positioning assemblies 20 move synchronously relatively or oppositely through a link mechanism 30. The positioning assembly 20 includes a sliding seat 21, a plurality of positioning plates 22 fixed at the upper end of the sliding seat 21 and spaced along the x direction, extension plates 23 fixed at both ends of the sliding seat 21 along the x direction, a mounting seat 24 fixed on the extension plate 23 and capable of adjusting the mounting position along the x direction, a second lifting drive device 25 fixed on the mounting seat 24 and capable of driving along the z direction, and a limit post 26 fixed on the output shaft of the second lifting drive device 25. A pulley 41 for conveying along the y direction is provided at one end of the positioning plate 22 facing the link mechanism 30. An avoidance hole 111 for the positioning plate 22 and the limit post 26 to pass through and move along the y direction is provided on the storage rack 11.

[0030] The steel structure welding positioning device of this embodiment is applicable to the welding pre-positioning of the horizontal frame 51, vertical frame 52 and corner code 53. Please refer to Figure 7 and Figure 8, during positioning, according to the length of the vertical frame 52, the link mechanism 30 is used to drive the two positioning components 20 to move synchronously relatively or oppositely, adjust the distance between the two positioning plates 22 opposite to each other in the y direction to be equal to the length of the vertical frame 52, and then use the first lifting drive device 12 to drive the support plate 13 to move upward, so that the positioning plate 22 passes upward through the avoidance hole 111 of the storage rack 11, place the two horizontal frames 51 on the opposite sides of the two positioning plates 22 respectively, use the positioning plate 22 to limit the horizontal frame 51, then adjust the installation position of the mounting seat 24 in the x direction, use the second lifting drive device 25 to drive the limit post 26 to penetrate upward through the avoidance hole 111, and set the positioning hole 531 of the angle code 53 on the limit post 26, limit the angle code 53 through the limit post 26, and then place the two vertical frames 52 between the two angle codes 53 opposite to each other in the y direction respectively, and the positioning can be completed. After the positioning is completed, welding is carried out to form a steel structure frame.

[0031] In addition, this embodiment is also provided with pulleys 41. When it is necessary to cut and transfer the steel structure frame, first drive the limit post 26 to retract downward through the second lifting drive device 25, and then use the first lifting drive device 12 to continue to drive the support plate 13 to move upward. The support plate 13 drives the positioning plate 22 and the pulley 41 to move upward until the pulley 41 lifts the steel structure frame. By the rolling action of the pulley 41, the steel structure frame can move in the x direction. Then place a conveying trolley on one side of the frame 10 in the x direction, and transfer the steel structure frame to the conveying trolley to reduce the difficulty of cutting and transferring.

[0032] Furthermore, please refer to Figure 3 , the frame 10 of this embodiment is provided with a strengthening column 14 to improve the structural strength of the frame 10. An installation plate 15 is fixed on the strengthening column 14, the first lifting drive device 12 is fixed on the installation plate 15, and the support plate 13 moves in the z direction above the installation plate 15.

[0033] Furthermore, please refer to Figure 6 , universal casters 16 are provided at the bottom of the frame 10 for easy movement.

[0034] Please refer to Figure 5 , the support plate 13 is provided with a guide rail 17 in the y direction, and the bottom of the sliding seat 21 is provided with a guide groove that slidably cooperates with the guide rail 17. Through the guiding action of the guide rail 17, the smoothness of the sliding seat 21 moving in the x direction is improved.

[0035] Further, the linkage mechanism 30 includes a bottom plate 31 fixed on the guide rail 17, a push-pull device 32 fixed on the bottom plate 31 and driven in the y direction, a first connecting plate 33 rotatably connected to the middle of the bottom plate 31, and two second connecting plates 34 respectively hinged to both ends of the first connecting plate 33. The other ends of the two second connecting plates 34 are respectively hinged to the two sliding seats 21. The output end of the push-pull device 32 is fixedly connected to any one of the sliding seats 21. After the push-pull device 32 is started, it can directly drive one sliding seat 21 to move in the y direction. Since both sliding seats 21 are hinged with second connecting plates 34, and the two second connecting plates 34 are also hinged to the first connecting plate 33, the other sliding seat 21 can be driven to move synchronously relatively or in the opposite direction, with a clever structure.

[0036] Further, one end of a pulley 41 is connected with a driven wheel 42. All the driven wheels 42 on the same positioning assembly 20 are synchronously driven by a belt 43. A motor 44 and a driving wheel 45 for driving the belt 43 are further provided on any one of the positioning plates 22. By driving the driving wheel 45 with the motor 44, the belt 43 is driven to rotate by the driving wheel 45, so as to synchronously drive all the driven wheels 42 to rotate. One motor 44 can synchronously drive all the pulleys 41, with a clever structure.

[0037] In addition, the limiting post 26 of this embodiment is detachably fixed to the output shaft of the second lifting driving device 25. Specifically, detachable fixing methods such as bolt fixing and screw matching can be adopted. Users can select and replace the limiting posts 26 with different sizes according to the aperture size of the positioning holes 531 of the angle code 53, with better compatibility.

[0038] Please refer to Figure 3 and Figure 4 , an installation hole 231 in the x direction is provided on the extension plate 23 of this embodiment. The mounting seat 24 is fixed to the extension plate 23 by the cooperation of bolt fasteners and the installation hole 231. Users can adjust the installation position of the mounting seat 24 in the x direction according to the length and position of the horizontal frame 51, so as to adjust the position of the limiting post 26 to meet different positioning requirements.
