Abstract
Description
Technical Field
[0001] This invention belongs to the field of welding equipment technology, specifically relating to a portable intelligent welding device for prefabricated curtain walls. Background Technology
[0002] Laser welding uses high-energy laser pulses to locally heat a small area of material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material and forming a specific molten pool to achieve the purpose of welding.
[0003] like Figure 1 As shown, during curtain wall installation, the curtain wall columns are fixed by pre-embedded plates embedded in the wall and corner plates welded to the pre-embedded plates, thus realizing the installation of the curtain wall. The welding operation between the corner plates and the pre-embedded plates usually adopts three-sided welding. The existing welding operation often uses a handheld laser welder to continuously weld the three sides of the corner plates. The welding quality depends on the worker's skill level. The worker needs to move the laser welder at a uniform speed, otherwise it will lead to uneven welds, which will affect the quality and strength of the welding. Moreover, manual welding is inefficient. Summary of the Invention
[0004] The purpose of this invention is to provide a portable intelligent welding device for pre-installed curtain walls to solve the problems of poor welding quality and low efficiency in the existing curtain wall installation process.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A portable pre-installed intelligent curtain wall welding device includes a frame and two clamping frames opposite each other on one side of the frame. A magnetic base is fixed to one side of the frame. One clamping frame is fixedly connected to the frame, and the other clamping frame is slidably connected to the frame. An L-shaped guide rail is slidably connected to the bottom of each clamping frame. Two sets of U-shaped frames are slidably connected between the two guide rail frames. An L-shaped guide rail is provided in the middle of each guide rail frame. A support frame is slidably connected to the bottom of each guide rail frame. A laser welder is fixedly installed at one end of the support frame. Three sliding columns are fixedly installed on one side of the support frame. The three sliding columns are slidably engaged with both sides of the L-shaped guide rail.
[0006] Preferably, the laser welder is tilted, and the emission port of the laser welder is close to the plane of the magnetic attraction surface of the magnetic seat.
[0007] Preferably, rollers are rotatably connected to the outer sides of the three sliding columns, and rolling grooves are provided on both sides of the two L-shaped guide rails. The two sets of rolling grooves are connected to the middle of the two sets of U-shaped frames, and the three rollers are respectively rolled and engaged in the middle of the two sets of rolling grooves and the U-shaped frames.
[0008] Preferably, both guide rail frames are provided with sliding grooves, and a slider is fixed at the end of the U-shaped frame. The slider slides in the sliding groove, and a limiting plate is fixed at one end of the sliding groove to obstruct the slider.
[0009] Preferably, a second electric push rod is fixedly installed at the bottom of each of the two clamping frames, and the telescopic ends of the two second electric push rods are respectively fixedly connected to the two guide rail frames.
[0010] Preferably, the bottom of each of the two clamping frames is rotatably connected to a first synchronous pulley, the corner of each of the two guide rail frames is rotatably connected to a second synchronous pulley, one end of each of the two guide rail frames is slidably connected to a slide rod, the ends of each of the two slide rods are fixedly mounted with a tensioning frame, a spring is fixedly connected between each of the two tensioning frames and the corresponding end of the guide rail frame, the bottom of each of the two tensioning frames is rotatably connected to a tensioning wheel, and a synchronous belt is drivenly connected to the outer sides of the two tensioning wheels, the two first synchronous pulleys and the two second synchronous pulleys, and one side of the support frame is fixedly connected to the synchronous belt.
[0011] Preferably, each of the two clamping frames has a pressure rod slidingly passing through one end, and a movable frame is slidably provided on one side of the frame. The bottom of the movable frame is rotatably connected to the two pressure rods by a connecting rod.
[0012] Preferably, the distance between the two connecting rods and the rotating connection end of the pressure rod is less than the distance between the two connecting rods and the rotating connection end of the moving frame.
[0013] Preferably, the frame is slidably connected to a slide block, and a first electric push rod is fixedly installed on the slide block. The telescopic end of the first electric push rod is fixedly connected to the movable frame.
[0014] Preferably, a guide rod is fixedly installed inside the frame, and the guide rod slides through the clamping frame and slide block that are slidably connected to the frame.
[0015] Compared with the prior art, the present invention has the following advantages: (1) The present invention is equipped with a guide rail frame and a U-shaped frame. During the corner plate welding operation, the frame is fixed to the embedded plate by a magnetic seat, and then the corner plate is assisted in fixing by a clamping frame. The U-shaped frame connects the two guide rail frames. Then, by moving the guide rail frames and the support frame along the two guide rail frames and the U-shaped frame, the support frame drives the laser welder to move along the trajectory of the three-sided welding, thereby realizing the automatic laser welding operation of the corner plate. The welding speed can be controlled by the control system to ensure the welding quality. Compared with manual welding, the operation is simpler and more efficient.
[0016] (2) The present invention is provided with rollers, rolling grooves and timing belts. The timing belt drives the movement of the support frame, so that the sliding column is engaged with both sides of the L-shaped guide rail, and the three rollers roll in the middle of the two sets of rolling grooves and the U-shaped frame, so that the support frame moves smoothly in the L-shaped guide rails in the guide rail frame. At the same time, the orientation of the support frame can be changed, thereby driving the emission port of the laser welder to face the weld seam, thereby improving the welding quality and ensuring the welding strength.
[0017] (3) The present invention is provided with a slide bar, a spring, a tensioning frame and a tensioning wheel. When the guide rail moves away from the machine frame, the spring causes the slide bar to drive the tensioning frame and the tensioning wheel away from the guide rail, thereby keeping the synchronous belt taut. This facilitates the synchronous belt to drive the support frame and the laser welder to move at a constant speed during welding operations. When the guide rail moves closer to the machine frame, the first synchronous wheel causes the synchronous belt to pull the tensioning wheel, causing the tensioning frame and the slide bar to extend into the guide rail, while compressing the spring. This can prevent the synchronous belt from breaking and prevent the tensioning wheel from hitting the machine frame, ensuring the normal operation of the equipment.
[0018] (4) The two clamping frames of the present invention can clamp angle plates of different widths, so that when the two first synchronous belts and the two second synchronous belts move relative to each other, the tensioning wheel can still keep the synchronous belts taut, increasing practicality.
[0019] (5) When the corner plate is being assisted in fixing, the movable frame, connecting rod and pressure rod of the present invention abut against the inner side of the clamping frame that is fixed relative to the frame. Then, the movable frame is brought closer to the frame by the retraction of the first electric push rod. The connecting rod first pushes the pressure rod down to abut against the end of the corner plate that is in contact with the frame. Then the movable frame is brought closer to the frame. At this time, the pressure rod cannot move down. Since the distance between the two connecting rods and the rotating connection end of the pressure rod is less than the distance between the two connecting rods and the rotating connection end of the movable frame, the connecting rod pushes the two clamping frames closer to each other through the pressure rod, thereby clamping and fixing the corner plate. At the same time, the pressure rod presses against the corner plate and is close to the embedded plate to avoid the gap between the corner plate and the embedded plate being too large and causing welding failure.

[0022] Please see Figures 2-10 As shown, the present invention provides the following technical solution: A portable pre-installed intelligent curtain wall welding device includes a frame 1 and two clamping frames 11 opposite to each other on one side of the frame 1. A magnetic base 2 is fixed on one side of the frame 1. One clamping frame 11 is fixedly connected to the frame 1, and the other clamping frame 11 is slidably connected to the frame 1. An L-shaped guide rail frame 10 is slidably connected to the bottom of each clamping frame 11. Two sets of U-shaped frames 8 are slidably connected between the two guide rail frames 10. An L-shaped guide rail is provided in the middle of each of the two guide rail frames 10. A support frame 4 is slidably connected to the bottom of each of the two guide rail frames 10. A laser welder 3 is fixedly installed at one end of the support frame 4. Three sliding columns 5 are fixedly installed on one side of the support frame 4. The three sliding columns 5 are slidably engaged with both sides of the L-shaped guide rail. The laser welder 3 is tilted, and the emission port of the laser welder 3 is close to the plane of the magnetic attraction surface of the magnetic base 2; Rollers 27 are rotatably connected to the outer sides of the three sliding columns 5. Rolling grooves 23 are provided on both sides of the two L-shaped guide rails. The two sets of rolling grooves 23 are connected to the middle of the two sets of U-shaped frames 8. The three rollers 27 are respectively rolled and engaged in the middle of the two sets of rolling grooves 23 and the U-shaped frame 8. The bottom of each of the two clamping frames 11 is fixedly equipped with a second electric push rod 19, and the telescopic ends of the two second electric push rods 19 are respectively fixedly connected to the two guide rail frames 10. The bottom of each of the two clamping frames 11 is rotatably connected to a first synchronous wheel 6, and the corners of each of the two guide rail frames 10 are rotatably connected to a second synchronous wheel 17. One end of each of the two guide rail frames 10 is slidably connected to a slide rod 20, and the ends of each of the two slide rods 20 are fixedly installed with a tensioning frame 22. A spring 21 is fixedly connected between each of the two tensioning frames 22 and the end of the corresponding guide rail frame 10. The bottom of each of the two tensioning frames 22 is rotatably connected to a tensioning wheel 18. The outer sides of the two tensioning wheels 18, the two first synchronous wheels 6, and the two second synchronous wheels 17 are connected to a synchronous belt 7. One side of the support frame 4 is fixedly connected to the synchronous belt 7.
[0023] Based on the above-disclosed structure, when performing welding operations on the embedded plate and the corner plate: First, the magnetic seat 2 is activated by switching on the magnetic seat 2, which attracts the magnetic seat 2 onto the embedded plate, thereby fixing the frame 1 and the embedded plate relative to each other. At the same time, the clamping surface of the clamping frame 11, which is fixed relative to the frame 1, coincides with the bottom edge of the corner plate. Then, the welding side of the corner plate is pressed against the embedded plate, and the two clamping frames 11 are used to clamp and fix the corner plate. At this time, the support frame 4 is located at the end of one of the guide rail frames 10, and the emission port of the laser welder 3 is close to the intersection line of the magnetic attraction surface of the magnetic seat 2 and the clamping surface of the clamping frame 11, that is, the emission port of the laser welder 3 is directly opposite the connection between the corner plate and the embedded plate. Then, the laser welder 3 is activated and the second electric push rod 19 extends its telescopic end, causing the guide rail frame 10 to move along the support frame 4. This moves the laser welder 3 along one side of the weld seam and performs welding operations until the inner side of the guide rail frame 10 aligns with the vertical edge of the corner plate to be welded. At this point, the second electric push rod 19 stops extending its telescopic end and drives one of the second synchronous pulleys 17 to rotate via a motor. This causes the synchronous belt 8 to move outside the two tension pulleys 18, the two first synchronous pulleys 6, and the two second synchronous pulleys 17. Consequently, the synchronous belt 8 moves the support frame 4 along the trajectory formed by the two guide rail frames 10 and the two sets of U-shaped frames 8, allowing the laser welder 3 to move. Welding continues along one side of the weld seam, then the laser welder 3 is rotated to move along the vertical weld seam and continue welding. Finally, it is rotated again, causing the laser welder 3 to move along the other side of the weld seam and continue welding. Then, the rotation of the second synchronous wheel 17 is stopped and the second electric push rod 19 is retracted to its telescopic end. This allows the support frame 4 to drive the laser welder 3 to continue moving along the other side of the weld seam and continue welding, thus completing the three-sided welding operation of the corner plate. The control system ensures that the telescopic speed of the second electric push rod 19 matches the moving speed of the synchronous belt 8, thereby achieving uniform welding, ensuring welding quality and strength. The equipment can also perform automatic welding operations with high efficiency.
[0024] As described above, when the second electric push rod 19 extends its telescopic end, causing the guide rail frame 10 to move away from the machine frame 1, the spring 21 causes the slide rod 20 to move the tension frame 22 and the tension wheel 18 away from the guide rail frame 10, thereby keeping the synchronous belt 8 taut. This facilitates the synchronous belt 8 to drive the support frame 4 and the laser welder 3 to move at a constant speed during subsequent welding operations, achieving uniform welding operation. When the second electric push rod 19 retracts its telescopic end, causing the guide rail frame 10 to move closer to the machine frame 1, the first synchronous wheel 6 causes the synchronous belt 8 to pull the tension wheel 18, causing the tension frame 22 and the slide rod 20 to extend into the guide rail frame 10, while simultaneously compressing the spring 21. This prevents the synchronous belt 8 from breaking and also prevents the tension wheel 18 from hitting the machine frame 1 and causing damage, ensuring the normal operation of the equipment. In addition, when the two clamping frames 11 clamp angle plates of different widths, the tension wheel 18 can still keep the synchronous belt 8 taut, making it easy to achieve uniform welding operation and increasing practicality.
[0025] Preferably, each of the two guide rail frames 10 is provided with a sliding groove 24, and a slider 26 is fixed to the end of the U-shaped frame 8. The slider 26 is slidably engaged in the sliding groove 24, and a limiting plate 25 is fixed to one end of the sliding groove 24 to obstruct the slider 26. Based on this, the limiting plate 25 restricts the slider 26 within the sliding groove 26, so that the two sets of U-shaped frames 8 are always used to connect the two guide rail frames 10. When the support frame 4 moves within the area of the two sets of U-shaped frames 8, the roller 27 is restricted by the middle of the U-shaped frame 8 to prevent the support frame 4 from moving out and falling off.
[0026] In addition, regarding the auxiliary fixing of the corner plate, the following structure is preferred: Each of the two clamping frames 11 has a pressure rod 9 slidingly passing through one end. A movable frame 13 is slidably provided on one side of the frame 1. A connecting rod 12 is rotatably connected between the bottom of the movable frame 13 and the two pressure rods 9. The distance between the rotating connection ends of the two connecting rods 12 and the pressure rod 9 is less than the distance between the rotating connection ends of the two connecting rods 12 and the moving frame 13; The frame 1 is slidably connected to a slide block 15, and a first electric push rod 14 is fixedly installed on the slide block 15. The telescopic end of the first electric push rod 14 is fixedly connected to the movable frame 13. A guide rod 16 is fixedly installed inside the frame 1. The guide rod 16 slides through the clamping frame 11 and the slide block 15, which are slidably connected to the frame 1.
[0027] As can be seen from the above, when the diagonal plate is assisted in fixing, one side of the diagonal plate abuts against the clamping side of the clamping frame 11 which is fixed relative to the frame 1. Then, the first electric push rod 14 is activated to retract its telescopic end, causing the moving frame 13 to approach the frame 1. The moving frame 13 causes the two connecting rods 12 to first drive the pressure rod 9 downward until the end of the pressure rod 9 abuts against the diagonal plate. Then, the first electric push rod 14 continues to retract its telescopic end, causing the moving frame 13 to approach the frame 1. At this time, the pressure rod 9 cannot move downward. However, since the distance between the rotating connection ends of the two connecting rods 12 and the pressure rod 9 is less than the distance between the rotating connection ends of the two connecting rods 12 and the moving frame 13, one of the connecting rods 12 passes through the corresponding pressure rod 9. Push the clamping frame 11, which is slidably connected to the frame 1, closer to the clamping frame 11 fixed to the frame 1, so that the two clamping frames 11 move closer to each other, thereby clamping and fixing the diagonal plates of the two clamping frames 11. At the same time, the slide block 15 moves along the guide rod 16 on the frame 1, so that the first electric push rod 14 is always in the middle of the two clamping frames 11. Then, the first electric push rod 14 continues to retract its telescopic end, so that the moving frame 13 applies a certain pressure to the pressure rod 9 diagonal plates through the connecting rod 12, thereby pressing the pressure rod 9 against the diagonal plates, and then pressing the diagonal plates against the embedded plates, thereby achieving auxiliary fixing of the diagonal plates and avoiding excessive gaps between the diagonal plates and the embedded plates, thus preventing welding failure.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
