Abstract
Description
Technical Field
[0001] This invention relates to the field of welding technology, and more specifically to the field of welding technology for prefabricated building steel structures, and particularly to a welding device for reinforcing prefabricated building steel structures. Background Technology
[0002] In the field of prefabricated buildings, steel structures are widely used due to their advantages such as high strength and short construction period. To ensure the overall stability of the steel structure, it is usually necessary to weld reinforcing ribs at its base to improve the structure's load-bearing capacity. Currently, the welding of reinforcing ribs mostly relies on traditional manual operation. The specific process includes manually picking up the reinforcing ribs to the designated welding position, manually adjusting the positioning, temporarily fixing them with clamps, and then welding them.
[0003] This traditional process has significant limitations: First, manual material loading and positioning are time-consuming, especially in batch welding operations, leading to low construction efficiency and failing to meet the rapid construction needs of prefabricated buildings. Second, the accuracy of manual fixing is greatly affected by operator experience, easily resulting in stiffener misalignment, which in turn affects welding quality and structural stability. Third, manual assistance during welding increases the risk of contact between operators and the high-temperature welding torch, posing certain safety hazards. Therefore, a welding device capable of automated material loading and auxiliary fixing is needed to solve the efficiency, accuracy, and safety issues of the traditional process. Summary of the Invention
[0004] This invention addresses the current practice of manually picking up reinforcing ribs to designated welding positions, manually adjusting their positioning, and temporarily fixing them with clamps before welding. It provides a welding device for reinforcing prefabricated building steel structures that can automatically feed materials and provide auxiliary fixing and positioning, completely replacing manual operation and effectively solving the problems mentioned in the background art.

[0007] The lower end of the grooved wheel is coaxially fixed to a first bevel gear, the lower end of the first bevel gear meshes with a second bevel gear, and the chuck is coaxially fixed to the front end of the second bevel gear.
[0008] A long cam is fixedly connected to the middle of the outer surface of the drive shaft, and a stand is fixedly connected to the upper surface of the operating box. A sleeve that is slidably connected to the stand is fitted on the outer surface of the long cam. A first sliding pin is fixedly connected to the inner wall of the sleeve. An upper circular groove, a first oblique arc groove, a lower circular groove, and a second oblique arc groove that cooperate with the first sliding pin are opened on the outer surface of the long cam. The suction cup is installed on the sleeve.
[0009] The sleeve has a vertical plate at the front end, and a movable horizontal plate is slidably connected to the front surface of the vertical plate. The front end of the vertical plate is also provided with a first threaded rod that can rotate. The movable horizontal plate is threaded to the outer surface of the first threaded rod. A feeding rod that can move back and forth is slidably connected to the inner wall of the movable horizontal plate. The suction cup is fixed to the lower end of the feeding rod.
[0010] A top plate is fixed to the upper surface of the stand, and a first slider is slidably connected to the inner wall of the top plate. A second sliding pin that can move back and forth is fixed to the lower surface of the first slider. A long connecting rod is fixed to the upper surface of the first slider, and an inner rod is fixed to the inner wall of the front end of the long connecting rod. The inner rod is slidably connected to the inner wall of the feeding rod.
[0011] The upper end of the outer surface of the drive shaft is fixedly connected to a drive disc that cooperates with the second sliding pin. The upper end of the drive disc is slidably connected to a protruding plate that cooperates with the second sliding pin. The upper end of the drive disc is provided with a small threaded rod that can rotate. The outer surface of the small threaded rod is threadedly connected to a threaded seat that is fixedly connected to the protruding plate. The inner wall of the top plate is fixedly connected to a first spring that cooperates with the first slider.
[0012] The upper end of the control box is slidably connected to a support plate, and the material seat is fixedly connected to the front surface of the support plate. The upper end of the control box is also provided with a rotatable second threaded rod, and the support plate is threadedly connected to the outer surface of the second threaded rod. The inner wall of the material seat is slidably connected to a pusher plate, and the inner wall of the material seat is also provided with a second spring that cooperates with the pusher plate. The lower inner wall of the material seat is provided with a discharge port that cooperates with the reinforcing rib.
[0013] The clamp includes a cross seat, which is fixed to the rear end surface of the clamping plate. Four evenly distributed third telescopic rods are fixed to the outer end face of the cross seat. Four evenly distributed drive plates are slidably connected to the rear end surface of the clamping plate. The drive plates are all fixed to the telescopic ends of the third telescopic rods. Clamping plates are provided on both sides of the front end of the drive plates.
[0014] Both sides of the control box are slidably connected to side slide plates. Both sides of the control box are also provided with first telescopic rods for driving the side slide plates to move up and down. The inner wall of the front end of the side slide plates is slidably connected to square sliders. The inner wall of the front end of the side slide plates is also fixedly connected to second telescopic rods for driving the square sliders to move back and forth. The welding guns are all installed on the corresponding square sliders.
[0015] Compared with the prior art, the present invention has the following advantages: In use, when the clamp moves inward, it can clamp and fix the base, preventing the base from moving during welding. When the drive shaft rotates, it can drive the clamp, fixture, and base to rotate and move, allowing welding of the base in multiple directions when welding and fixing the reinforcing ribs. The feeding mechanism can push the reinforcing ribs to the designated position on the base. The material holder is used to support and place the reinforcing ribs. When the suction cup works, it can adsorb and fix the reinforcing rib on the far side of the material holder. After adsorption and fixation, when the drive shaft rotates, it can make the suction cup, reinforcing ribs, etc., move downward and backward simultaneously, so that the reinforcing ribs are tightly attached to the base, thus facilitating welding. Through the welding mechanism that can move up and down and forward and backward, the reinforcing ribs, base, etc., can be welded and fixed. Automated feeding is also possible. The mechanism enables automatic feeding and positioning of reinforcing ribs, eliminating manual handling and adjustment, significantly shortening the pre-processing time for individual reinforcing ribs. This is particularly beneficial in batch operations, significantly improving overall welding efficiency and meeting the requirements of rapid construction in prefabricated buildings. The mechanically assisted fixing structure allows for precise control of the reinforcing rib installation position and angle, avoiding positioning deviations caused by manual operation, ensuring consistent welding quality, and enhancing the overall stability of the steel structure. Automated feeding and fixing reduce direct contact between operators and the welding area, lowering the probability of accidents such as high-temperature burns and weld spatter, and improving the safety of the working environment. Reducing reliance on manual assistance and the need for skilled workers effectively saves labor costs and improves the economic efficiency of construction in long-term operations.

Detailed Implementation
[0030] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0031] like Figures 1-14 As shown, the present invention provides a welding device for reinforcing prefabricated building steel structures, including an operation box 2. The inner wall of the operation box 2 is provided with a clamping plate 13, and the clamping plate 13 is provided with a fixture for fixing the base. The upper end of the operation box 2 is provided with a rotatable drive shaft 51. When the drive shaft 51 rotates, the clamping plate 13 and the fixture can rotate intermittently. The upper end of the operation box 2 is provided with a feeding mechanism, which includes a feeding rod 39. The upper end of the operation box 2 is also provided with a material seat 44, and multiple reinforcing ribs are placed inside the material seat 44. The lower end of the feeding rod 39 is provided with a suction cup 40 for adsorbing and fixing the reinforcing ribs. When the drive shaft 51 rotates, the suction cup 40 and the reinforcing ribs can move downward and backward, so that the reinforcing ribs are in close contact with the base. The front end of the operation box 2 is also provided with a welding gun 7 that can move up and down and forward and backward.
[0032] like Figures 1-7As shown, the bottom of the operation box 2 is fixed with a foot 1, which is placed on the ground and used to support the entire device. The operation box 2 is used to install the corresponding parts. The clamp 13 is used to install the clamp, which can move inward or outward. By placing the base at the front end of the clamp 13, the base can be clamped and fixed when the clamp moves inward, thus preventing the base from moving during welding. When the drive shaft 51 rotates, it can drive the clamp 13, clamp, base, etc. to rotate and move. When welding and fixing the reinforcing rib, the base can be welded in multiple directions. The feeding mechanism can push the reinforcing rib to the designated position on the base. The material seat 44 is used to support and place the reinforcing rib. When the suction cup 40 works, it can adsorb and fix the reinforcing rib on the outermost side of the material seat 44. After adsorption and fixation, when the drive shaft 51 rotates, it can make the suction cup 40, reinforcing rib, etc. move downward and backward simultaneously, so that the reinforcing rib is close to the base, thus facilitating welding. The welding torch 7, which can move up and down and back and forth, can be used to weld and fix the reinforcing ribs and base. This is existing technology and will not be described further. An automated feeding mechanism automatically transports and positions the reinforcing ribs, eliminating manual handling and adjustment, significantly shortening the pre-processing time for a single reinforcing rib. This greatly improves overall welding efficiency, especially in batch operations, meeting the requirements of rapid construction in prefabricated buildings. The mechanically assisted fixing structure precisely controls the installation position and angle of the reinforcing ribs, avoiding positioning deviations caused by manual operation, ensuring consistent welding quality, and improving the overall stability of the steel structure. Automated feeding and fixing reduce direct contact between operators and the welding area, lowering the probability of accidents such as high-temperature burns and weld spatter, and improving the safety of the working environment. Reducing reliance on manual assistance lowers the demand for skilled workers, effectively saving labor costs and improving the economic efficiency of construction in long-term operations.
[0033] The operation box 2 is equipped with a first motor 8 inside, and a drive shaft 51 is fixedly connected to the output end of the first motor 8. The inner wall of the operation box 2 is equipped with an intermittent mechanism, which includes a lever 9 and a grooved wheel 10 that cooperate with each other. The lever 9 is fixedly connected to the lower end of the outer surface of the drive shaft 51, and the grooved wheel 10 is rotatably connected to the inner wall of the operation box 2. The clamping plate 13 is installed at the output end of the intermittent mechanism.
[0034] like Figure 7As shown, the first motor 8 has a motor base at its bottom, which is fixed to the inner wall of the operating box 2. This is equivalent to fixing the first motor 8 to the inner wall of the operating box 2. The function of the first motor 8 is to provide rotational power for the drive shaft 51, lever 9, etc. The motor is existing technology and will not be described in detail. The drive shaft 51 is rotatably connected to the inner wall of the operating box 2. A rotating shaft is fixed to the inner wall at the center of the grooved wheel 10, and the rotating shaft is rotatably connected to the inner wall of the operating box 2. When the first motor 8 is started, it can drive the lever 9 to rotate. When the lever 9 rotates, it can drive the grooved wheel 10 to rotate intermittently, and each time it rotates 90 degrees intermittently. This will also drive the clamping plate 13 to rotate intermittently, and each time it rotates 90 degrees, thereby performing welding processing on the base in the four directions of up, down, left, and right.
[0035] The lower end of the grooved wheel 10 is coaxially fixed to a first bevel gear 11, and the lower end of the first bevel gear 11 is meshed with a second bevel gear 12. The chuck 13 is coaxially fixed to the front end of the second bevel gear 12.
[0036] like Figure 7 As shown, a rotating shaft is fixedly connected to the inner wall of the grooved wheel 10 and the first bevel gear 11. The rotating shaft is rotatably connected to the inner wall of the operating box 2. A rotating shaft is fixedly connected to the inner wall of the chuck 13 and the second bevel gear 12. The rotating shaft is rotatably connected to the inner wall of the operating box 2. When the grooved wheel 10 rotates, it can drive the chuck 13 to rotate through the meshing of the first bevel gear 11 and the second bevel gear 12. That is, the grooved wheel 10, the chuck 13, etc. rotate synchronously.
[0037] A long cam 20 is fixedly connected to the middle of the outer surface of the drive shaft 51. A stand 18 is fixedly connected to the upper surface of the operation box 2. A sleeve 19 that is slidably connected to the stand 18 is sleeved on the outer surface of the long cam 20. A first sliding pin 21 is fixedly connected to the inner wall of the sleeve 19. An upper circular groove 22, a first oblique arc groove 25, a lower circular groove 24 and a second oblique arc groove 23 that cooperate with the first sliding pin 21 are opened on the outer surface of the long cam 20. The suction cup 40 is installed on the sleeve 19.
[0038] like Figures 9-11As shown, the stand 18 is used to support components such as the limiting sleeve 19. The sleeve 19 can slide up and down on the inner wall of the stand 18, meaning that the limiting first sliding pin 21 can only move up and down. Under the engagement of the first sliding pin 21 and the long cam 20, the first sliding pin 21 can intermittently move up and down. That is, when the long cam 20 rotates to the point where the first sliding pin 21 enters the upper circular groove 22 for engagement, the long cam 20 continues to rotate. Under the engagement of the first sliding pin 21 and the upper circular groove 22, the first sliding pin 21, sleeve 19, suction cup 40, etc., can be in the uppermost position and maintained for a period of time, providing rotation time for the clamping plate 13, fixture, base, etc., that is, the base changes the welding direction. At this time, the suction cup 40... When working, it can adsorb and fix the reinforcing rib. When the long cam 20 rotates to make the first sliding pin 21 engage with the first inclined arc groove 25, the long cam 20 continues to rotate, which can make the first sliding pin 21, suction cup 40 and other components move downward. When the long cam 20 rotates to make the first sliding pin 21 engage with the lower circular groove 24, the first sliding pin 21, suction cup 40 and other components can be at the bottom position and maintain it for a period of time, which provides a certain amount of time for the suction cup 40, reinforcing rib and other components to move backward. That is, when the long cam 20 rotates, it can make the suction cup 40 intermittently stop at the top position, then move downward to the bottom position and intermittently stop, and continue to move upward to the top position and then intermittently stop.
[0039] The sleeve 19 has a vertical plate 26 at its front end, and a movable horizontal plate 27 is slidably connected to the front surface of the vertical plate 26. The front end of the vertical plate 26 is also provided with a first threaded rod 28 that can rotate. The movable horizontal plate 27 is threadedly connected to the outer surface of the first threaded rod 28. A feeding rod 39 that can move back and forth is slidably connected to the inner wall of the movable horizontal plate 27. The suction cup 40 is fixed to the lower end of the feeding rod 39.
[0040] like Figure 8 and Figure 12 As shown, the movable horizontal plate 27 can slide up and down on the inner wall of the vertical plate 26. Bearing seats are rotatably connected to both ends of the outer surface of the first threaded rod 28. The bottom end of the bearing seat is fixed to the front end surface of the vertical plate 26, limiting the rotation of the first threaded rod 28 to the front end of the vertical plate 26. A first handle 29 is fixed to both ends of the outer surface of the first threaded rod 28. The function of the first handle 29 is to facilitate driving the rotation of the first threaded rod 28. The feed rod 39 can slide back and forth on the inner wall of the movable horizontal plate 27. When the sleeve 19, vertical plate 26, and movable horizontal plate 27 are connected... When the 7th rod moves up and down, it can drive the feed rod 39 and the suction cup 40 to move up and down synchronously. The feed rod 39 can also move back and forth. When the feed rod 39 moves back and forth, it can drive the suction cup 40 to move back and forth. The first threaded rod 28 and the movable horizontal plate 27 are threadedly connected. When the first threaded rod 28 rotates, it can drive the movable horizontal plate 27 to move up or down, that is, it can adjust the initial position of the vertical coordinate of the suction cup 40. When the first threaded rod 28 does not rotate, it has a self-locking function, that is, the position of the movable horizontal plate 27 is in a fixed state.
[0041] A top plate 30 is fixedly connected to the upper surface of the stand 18. A first slider 32 is slidably connected to the inner wall of the top plate 30. A second sliding pin 33 that can move back and forth is fixedly connected to the lower surface of the first slider 32. A long connecting rod 41 is fixedly connected to the upper surface of the first slider 32. An inner rod 42 is fixedly connected to the inner wall of the front end of the long connecting rod 41. The inner rod 42 is slidably connected to the inner wall of the feeding rod 39.
[0042] like Figure 12 As shown, the top plate 30 is used to limit and support components such as the first slider 32 and the long connecting rod 41. The first slider 32 can slide back and forth on the inner wall of the top plate 30, which limits the second sliding pin 33, the long connecting rod 41, etc. to only move back and forth. When the second sliding pin 33 moves back and forth, it can drive the first slider 32, the long connecting rod 41, the inner rod 42, etc. to move back and forth synchronously. When the inner rod 42 moves back and forth, it will drive the feeding rod 39, the suction cup 40, etc. to move back and forth. When the feeding rod 39 moves up and down, it can slide down along the outer surface of the inner rod 42. That is, through the connection between the inner rod 42 and the feeding rod 39, the movements of the two do not affect each other.
[0043] The upper end of the outer surface of the drive shaft 51 is fixedly connected to a drive disk 34 that cooperates with the second sliding pin 33. The upper end of the drive disk 34 is slidably connected to a protruding plate 35 that cooperates with the second sliding pin 33. The upper end of the drive disk 34 is provided with a rotatable small threaded rod 36. The outer surface of the small threaded rod 36 is threadedly connected to a threaded seat 37 that is fixedly connected to the protruding plate 35. The inner wall of the top plate 30 is fixedly connected to a first spring 31 that cooperates with the first slider 32.
[0044] like Figure 12As shown, the first slider 32 and the second sliding pin 33 have a forward driving force under the elastic force of the first spring 31, so that the first slider 32 and the second sliding pin 33 are in the foremost position under normal conditions, that is, the second sliding pin 33 can contact and engage with the outer surface of the drive disk 34 under normal conditions; the convex plate 35 can slide inward or outward on the inner wall of the drive disk 34, that is, when the convex plate 35 moves outward, it can protrude more, and when the convex plate 35 moves inward, it can retract partly; a bearing plate is fixedly connected to the upper end of the drive disk 34, and the small threaded rod 36 is rotatably connected to the inner wall of the bearing plate, limiting the small threaded rod 36 to only rotate. A small handle 38 is fixedly connected to the outer surface of the small threaded rod 36, and the function of the small handle 38 is to facilitate the rotation of the small threaded rod 36; when the small threaded rod 36 is driven to rotate, the convex plate 35 can be driven to move inward or outward through the threaded connection between the threaded seat 37 and the small threaded rod 36, that is, to adjust. The position of the convex plate 35, and when the threaded rod is not rotating, has a self-locking function under the threaded connection between the small threaded rod 36 and the threaded seat 37, that is, the positions of the threaded seat 37 and the convex plate 35 on the upper surface of the drive disk 34 are fixed; when the drive disk 34, the convex plate 35, etc. rotate, through the cooperation with the second sliding pin 33, the second sliding pin 33 can be moved back and forth intermittently, that is, when the second sliding pin 33 contacts and engages with the drive disk 34, the drive disk 34 rotates, and the second sliding pin 33 is at the designated position at the front end, that is, the intermittent stop state; when the drive disk 34 rotates to make the second sliding pin 33 contact and engage with the convex plate 35, the second sliding pin 33 can be moved backward, and after moving backward to the top, it moves forward again, that is, after the second sliding pin 33 moves back and forth once, it returns to the front end position and stops, that is, the corresponding suction cup 40 moves back and forth once and returns to the front end position and stops.With the intermittent mechanism and the feeding mechanism working together, when the drive shaft 51 rotates, it can drive the long cam 20, drive disk 34, lever 9, etc. to rotate synchronously. When the lever 9 rotates, through meshing with the grooved wheel 10, it can drive the grooved wheel 10, the base, etc. to rotate 90 degrees and then stop intermittently. Even if the surface to be welded is facing upwards, when the long cam 20 rotates, it can drive the movable horizontal plate 27, suction cup 40, reinforcing rib, etc. to move intermittently downwards. When the suction cup 40 moves downwards to the designated position, that is, when it contacts the upper end surface of the base, it can stop intermittently. At this time, under the meshing of the drive disk 34, the convex plate 35 and the second sliding pin 33, the suction cup will be moved again. 40. The reinforcing ribs move backward synchronously until they contact the front surface of the base, ensuring they are firmly attached to the designated position on the base. At this point, the first motor 8 is controlled to stop the drive shaft 51 from rotating, and the welding torch 7 is activated to weld and fix the reinforcing ribs and the base. After welding and fixing, the first motor 8 is started again to rotate the drive shaft 51. When the drive shaft 51 rotates, it drives the long cam 20, drive plate 34, lever 9, etc., to continue rotating synchronously. With the cooperation of the drive plate 34, the convex plate 35, and the second sliding pin 33, the suction cup 40 can be moved forward and reset first. When the suction cup 40 resets, it does not... Next, the reinforcing rib is adsorbed and fixed. With the cooperation of the long cam 20 and the first sliding pin 21, the suction cup 40 can be moved upward and reset. Then, with the cooperation of the lever 9 and the grooved wheel 10, the base is rotated to the designated position again, so that the next end face can be welded. That is, the working sequence is as follows: when the drive shaft 51 rotates, the base is rotated to a designated angle by the engagement of the lever 9 and the grooved wheel 10. Then, with the cooperation of the long cam 20 and the first sliding pin 21, the suction cup 40 and the reinforcing rib are moved downward to the designated position. Finally, with the cooperation of the drive disc 34, the protruding plate 35 and the second sliding pin 33, the suction cup 40 and the reinforcing rib are moved backward to the designated position. Positioning is achieved by fixing the position of the reinforcing rib, preparing for welding. As the drive shaft 51 continues to rotate, the suction cup 40 moves forward and then back upward to reset, allowing the corresponding base to rotate 90 degrees for welding the next end face. When the first threaded rod 28 rotates, the initial positions of the movable cross plate 27 and suction cup 40 can be adjusted, adapting to the base model. When the small threaded rod 36 rotates, it drives the protruding plate 35 to move inward or outward, thereby adjusting the stroke of the suction cup 40, adapting to the reinforcing rib model.
[0045] The upper end of the operation box 2 is slidably connected to a support plate 43, and the material seat 44 is fixedly connected to the front surface of the support plate 43. The upper end of the operation box 2 is also provided with a rotatable second threaded rod 46, and the support plate 43 is threadedly connected to the outer surface of the second threaded rod 46. The inner wall of the material seat 44 is slidably connected to a pusher plate 49, and the inner wall of the material seat 44 is also provided with a second spring 48 that cooperates with the pusher plate 49. The lower inner wall of the material seat 44 is provided with a discharge port 50 that cooperates with the reinforcing rib.
[0046] like Figures 13-14 As shown, two short guide rods 45 are fixedly connected to the upper surface of the operating box 2. The support plate 43 is slidably connected to the outer surface of the two short guide rods 45, which is equivalent to the support plate 43 being slidably connected to the upper end of the operating box 2. The second threaded rod 46 is rotatably connected to the inner wall of the operating box 2. A second handle 47 is fixedly connected to the upper surface of the second threaded rod 46. The function of the second handle 47 is to facilitate the rotation of the second threaded rod 46. Through the threaded connection between the second threaded rod 46 and the support plate 43, when the second threaded rod 46 rotates, it can drive the support plate 43 to move up or down, thereby adjusting the vertical height of the support plate 43, the material seat 44, and the reinforcing rib. The position of the material seat 44 and the reinforcing rib can be adjusted according to the position of the suction cup 40. When the second threaded rod 46 is not rotating, it also has a self-locking function, that is, the positions of the support plate 43, the material seat 44, etc. are in a fixed state. The installation and shape of the material seat 44, the push plate 49, and the second spring 48 are as follows. Figure 14 As shown, the second spring 48 always exerts a leftward driving force on the pusher plate 49, so that the pusher plate 49 can push the reinforcing ribs under normal conditions, making the reinforcing ribs closely arranged; the discharge port 50 is set corresponding to the reinforcing ribs. When the suction cup 40 adsorbs and fixes the reinforcing ribs, it can drive the reinforcing ribs to move downward when the suction cup 40 moves downward, that is, the reinforcing ribs are moved out through the discharge port 50 to the inner wall of the material seat 44.
[0047] The clamp includes a cross seat 14, which is fixed to the rear end surface of the clamping plate 13. Four evenly distributed third telescopic rods 15 are fixed to the outer end face of the cross seat 14. Four evenly distributed drive plates 16 are slidably connected to the rear end surface of the clamping plate 13. The drive plates 16 are all fixed to the telescopic ends of the third telescopic rods 15. Clamping plates 17 are provided on both sides of the front end of the drive plates 16.
[0048] like Figure 6 and Figure 8 As shown, when the drive plate 16 and clamping plate 17 move inward or outward, the clamps close or open; when the third telescopic rod 15 extends and retracts synchronously, it enables the drive plate 16, clamping plate 17, etc., to move inward or outward. The telescopic rod is existing technology and will not be described in detail.
[0049] Both sides of the operation box 2 are slidably connected to side slide plates 4. Both sides of the operation box 2 are also provided with first telescopic rods 3 for driving the side slide plates 4 to move up and down. The inner wall of the front end of the side slide plates 4 is slidably connected to square sliders 6. The inner wall of the front end of the side slide plates 4 is also fixedly connected to second telescopic rods 5 for driving the square sliders 6 to move back and forth. The welding guns 7 are all installed on the corresponding square sliders 6.
[0050] like Figures 4-5As shown, the bottom of the first telescopic rod 3 is fixed to the two end faces of the operating box 2. The side slide plate 4 can slide up and down to the inner wall of the operating box 2. When the first telescopic rod 3 extends and retracts, it can drive the side slide plate 4, the square slide 6, the welding torch 7, etc. to move up and down. The square slide plate 6 can slide back and forth to the inner wall of the side slide plate 4. When the second telescopic rod 5 extends and retracts, it can drive the square slide plate 6, the welding torch 7, etc. to move back and forth, thereby controlling the welding torch 7 to move forward and backward or up and down.
[0051] In use, this invention can clamp and fix the base when the clamp moves inward, preventing the base from moving during welding. When the drive shaft 51 rotates, it can drive the clamping plate 13, clamp, base, etc., to rotate and move, allowing welding processing of the base in multiple directions when welding and fixing the reinforcing ribs. The feeding mechanism can push the reinforcing ribs to the designated position on the base. The material seat 44 is used to support and place the reinforcing ribs. When the suction cup 40 works, it can adsorb and fix the reinforcing rib on the outermost side of the material seat 44. After adsorption and fixation, when the drive shaft 51 rotates, it can cause the suction cup 40, reinforcing ribs, etc., to move downward and backward simultaneously, so that the reinforcing ribs are close to the base, thus facilitating welding. Through the welding mechanism that can move up and down and forward and backward, the reinforcing ribs, base, etc., can be welded and fixed. The automated feeding mechanism enables automatic conveying and positioning of reinforcing ribs, eliminating manual handling and adjustment, significantly shortening the pre-processing time for a single reinforcing rib. This is particularly beneficial in batch operations, significantly improving overall welding efficiency and meeting the requirements of rapid construction in prefabricated buildings. The mechanically assisted fixing structure allows for precise control of the reinforcing rib's installation position and angle, avoiding positioning deviations caused by manual operation, ensuring consistent welding quality, and enhancing the overall stability of the steel structure. Automated feeding and fixing reduce direct contact between operators and the welding area, lowering the probability of accidents such as high-temperature burns and weld spatter, and improving the safety of the working environment. Reducing reliance on manual assistance lowers the demand for skilled workers, effectively saving labor costs and improving the economic efficiency of construction in long-term operations.
