[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5As shown in the figure, the utility model provides a welding device for a building steel structure frame, which includes a base 1. A first motor 2 is fixedly installed on the right side of the top of the base 1. The other end of the output shaft of the first motor 2 is fixedly sleeved with a rotating shaft 3. A rotating rod 4 is fixedly sleeved on the outer surface of the rotating shaft 3. The other end of the rotating rod 4 is hinged with a transmission rod 5. The other end of the transmission rod 5 is hinged with a pushing plate 6. A long groove 7 is opened in the middle of the top of the base 1. The right side of the bottom end of the pushing plate 6 is fixedly connected with a limiting block 8. The bottom end of the limiting block 8 passes through the long groove 7 and extends into the interior of the long groove 7. The outer surface of the limiting block 8 is movably connected with the inner surface of the long groove 7.

[0024] When the first motor 2 is running, it will cause the rotating shaft 3 to drive the rotating rod 4 to rotate. At this time, the transmission rod 5 will push the pushing plate 6 to move leftward, thereby driving the welded steel plate on the top of the pushing plate 6 to move leftward, which is convenient for subsequent operators to collect it.

[0025] Among them, the top of the front and rear sides of the base 1 is movably connected with a support frame 9. A first air cylinder 10 is fixedly installed on the top of the support frame 9. The bottom end of the first air cylinder 10 passes through the support frame 9 and extends into the interior of the support frame 9 and is fixedly connected with a movable plate 11.

[0026] When the first air cylinder 10 is running, it will cause the movable plate 11 to move downward.

[0027] Among them, a round block 12 is fixedly installed in the middle of the bottom end of the movable plate 11. A hollow block 13 is movably sleeved on the outer surface of the round block 12. A rectangular block 14 is fixedly installed at the bottom end of the hollow block 13. Both the front and rear sides of the bottom end of the movable plate 11 are fixedly connected with a first spring 15. The number of the first springs 15 is two. The other ends of the two first springs 15 are both fixedly connected with the top end of the rectangular block 14. A welding rod 16 is fixedly installed at the bottom end of the rectangular block 14.

[0028] When the bottom end of the welding rod 16 contacts the surface of the steel structure to be welded, at this time, the movable plate 11 will drive the round block 12 to move downward in the hollow block 13 and compress the first spring 15, thereby playing an effect of collision buffering.

[0029] Among them, fixing blocks 17 are fixedly installed on both the left and right sides of the bottom end of the front of the base 1. A second motor 18 located on the right side of the base 1 is fixedly installed on the right side of the fixing block 17. The other end of the output shaft of the second motor 18 is fixedly sleeved with a lead screw 19. The other end of the lead screw 19 passes through the fixing block 17 and extends to the left side of the fixing block 17. A slider 20 is threadedly sleeved on the outer surface of the lead screw 19. A connecting rod 21 is fixedly installed on the top of the slider 20. The top end of the connecting rod 21 is fixedly connected with the bottom end of the support frame 9.

[0030] When the second motor 18 is running, it will cause the lead screw 19 to rotate. At this time, the slider 20 will move left and right on the surface of the lead screw 19, thereby driving the connecting rod 21 and the support frame 9 to move left and right as a whole.

[0031] Wherein, clamping blocks 22 are movably installed on both the front and rear sides of the middle part of the top end of the base 1. Short grooves 23 are formed on both the front and rear sides of the top end of the base 1 and are located directly below the clamping blocks 22. The bottom ends of the clamping blocks 22 are fixedly connected with moving blocks 24. The number of the moving blocks 24 is two. The bottom ends of the two moving blocks 24 pass through the short grooves 23 and extend into the interior of the base 1. A second spring 25 is fixedly installed inside the short groove 23, and the other end of the second spring 25 is fixedly connected with the outer surface of the moving block 24.

[0032] Due to the presence of the clamping blocks 22, the steel plate to be welded will be clamped and fixed to prevent the steel plate from shifting during welding. At this time, the second spring 25 is in a stretched state.

[0033] Wherein, a fixing frame 26 is fixedly installed at the bottom of the inner cavity of the base 1. A second air cylinder 27 is fixedly connected inside the fixing frame 26. The top end of the second air cylinder 27 penetrates through the fixing frame 26 and extends above the fixing frame 26 and is fixedly installed with a moving rod 28. Fixing shafts 29 are fixedly installed at both the front and rear ends on the right side of the moving rod 28. The number of the fixing shafts 29 is two, and the two fixing shafts 29 have the same size.

[0034] When the second air cylinder 27 is running, it will cause the moving rod 28 to move downward.

[0035] Wherein, both the front and rear sides of the top end of the fixing frame 26 are hinged with inclined rods 30 located on the right side of the second air cylinder 27. The number of the inclined rods 30 is two. The two inclined rods 30 are located between the two fixing shafts 29. Circular shafts 31 are fixedly installed at the top ends on the right sides of the two inclined rods 30. The other ends of the circular shafts 31 penetrate through the inclined rods 30 and extend into the interior of the moving blocks 24.

[0036] When the moving rod 28 moves downward, the two fixing shafts 29 will gradually release the blocking effect on the two inclined rods 30. At this time, due to the elastic recovery effect of the second spring 25, it will pull the two moving blocks 24 to move away from each other, thereby driving the two clamping blocks 22 to move away from each other, and further releasing the fixing effect on the welded steel plate, so as to push it out below the welding rod 16 subsequently.

[0037] Wherein, limiting grooves 32 are formed on both the front and rear sides of the top end of the base 1. Movable blocks 33 are movably installed inside the limiting grooves 32. The outer surface of the movable blocks 33 is fixedly connected with the inner surface of the support frame 9.

[0038] Due to the cooperation of the limiting grooves 32 and the movable blocks 33, it will have a good limiting effect on the movement of the support frame 9.

[0039] Working principle and usage process of the utility model:

[0040] First, the operator places the steel plate to be welded between the two clamping blocks 22, and then starts the second air cylinder 27, causing the moving rod 28 to move upward and the two fixed shafts 29 to squeeze the two inclined rods 30. At this time, the other end of the round shaft 31 will drive the two moving blocks 24 to move towards each other and stretch the second spring 25, thereby driving the two clamping blocks 22 to move towards each other and clamp and fix the steel plate to be welded. Subsequently, the operator starts the first air cylinder 10, causing the movable plate 11 to move downward, thereby driving the rectangular block 14 to move downward, making the bottom end of the welding rod 16 contact the surface of the steel plate to be welded. At this time, the operator starts the second motor 18, causing the lead screw 19 to rotate. At this time, the slider 20 will move left and right on the surface of the lead screw 19, thereby driving the entire support frame 9 to move left and right, making the bottom end of the welding rod 16 move left and right on the surface of the steel plate to be welded to complete the welding work.

[0041] When the steel plate is welded, at this time, the operator starts the first air cylinder 10 again, causing the movable plate 11 to move upward, thereby separating the bottom end of the welding rod 16 from the surface of the welded steel plate. Subsequently, the second air cylinder 27 is started again, causing the moving rod 28 to move downward. At this time, the fixed shaft 29 will gradually release the blocking effect on the inclined rod 30. At this time, due to the elastic force recovery of the second spring 25, it will pull the two moving blocks 24 to move away from each other, thereby driving the two clamping blocks 22 to move away from each other, thereby releasing the clamping and fixing effect on the steel plate, making the welded steel plate fall on the top of the pushing plate 6. At this time, the operator starts the first motor 2, causing the rotating shaft 3 to drive the rotating rod 4 to rotate. At this time, the transmission rod 5 will push the pushing plate 6 to move leftward, thereby pushing the welded steel plate out from under the welding rod 16 for subsequent operators to collect.
