Description

Technical Field

[0001] This invention relates to the field of control cabinet housing processing technology, and more specifically, to an auxiliary laser welding device for control cabinet housing production. Background Technology

[0002] Chinese Patent Publication No. CN115815809A discloses a welding device for a charging pile box partition; it includes: a limiting part for limiting the box; a guide rail is provided at the upper end of the limiting part, and a fixing part for fixing the partition is symmetrically provided on the guide rail; a welding part for welding the partition and the box is rotatably provided on the outer wall of the fixing part; a support part is provided at the lower end of the limiting part for supporting the limiting part, and a distance fixing part is provided on the support part for determining the position of the partition.

[0003] In the above technical solution, the partition is strictly extended horizontally into the box and fixed by external expansion and adsorption. This avoids the partition from being skewed during welding. However, in the traditional laser welding process for the control box, the control box plate to be welded is first placed on the welding table, and the docking angle of the plate is manually adjusted. After adjustment, the plate is fixed, and then the welding gun is used to weld the box plate. The manual adjustment of the docking angle affects the docking speed of the box plate, thus affecting the welding efficiency. In addition, the manual hand-held welding gun requires multiple adjustments to its position, making it impossible to ensure that the welding gun is accurately aligned with the welding position of the box plate. Moreover, during the adjustment of the welding gun, it is impossible to ensure that the protective gas outlet pipe is accurately aligned with the welding gap, thus affecting the welding quality of the box plate.

[0012] Preferably, a vertical frame is fixedly installed on the side surface of the welding equipment. An air pump is fixedly installed in the middle of the surface of the vertical frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) When using the auxiliary laser welding device for the production of this control cabinet enclosure, compared with traditional welding equipment, during the operation of this welding equipment, two enclosure plates to be welded are placed on the surfaces of flip plate one and flip plate two. Flip plate one and flip plate two rotate towards each other around the surface of the fixed column. When the included angle between the two enclosure plates after they have rotated towards each other is 90 degrees, the two enclosure plates move under their own weight, thereby making the bottom surface of the two enclosure plates contact the surface of the angle iron limit frame. At this time, the two enclosure plates are connected. There is no need for manual intervention to adjust the angle and fix the plates to be welded, which improves the connection speed of the welding equipment for the enclosure plates, and thus improves the welding efficiency of the welding equipment for the enclosure plates.

[0016] 2) When using the auxiliary laser welding device for the production of this control cabinet, the centering frame moves downward and first contacts the surfaces of the two cabinet panels. When the first ball bearing at one end of the centering frame contacts the surface of the cabinet panel, as the second telescopic device extends, the centering frame moves towards the other ball bearing. When both ends of the centering frame contact the surfaces of the two cabinet panels at the same time, the centering frame, carrying the laser welder, is aligned with the welding position, enabling the laser welder to quickly align with the welding position of the two cabinet panels, further improving the welding efficiency of the laser welder on the two cabinet panels.

[0017] 3) When using the auxiliary laser welding device for the production of this control cabinet, the surfaces of the two cabinet panels are simultaneously pressed against the two connecting frames. During the movement of the two connecting frames towards each other, rotating plates one and two rotate simultaneously. When rotating plates one and two rotate at the same angle as the two cabinet panels, multiple air jets on both sides also follow the movement of rotating plates one and two to adjust their angles. This allows the multiple air jets on both sides to be aligned with the butt weld of the two cabinet panels, achieving rapid alignment of the air jets with the butt weld of the two cabinet panels and ensuring the welding quality of the cabinet panels by the laser welder.

[0018] 4) When using the auxiliary laser welding device for the production of this control cabinet, the threaded rod is manually rotated according to the width of the cabinet plate to be welded. Under the action of the rotation of the threaded rod, the limiting frame moves inside the slot. The movement of the limiting frame moves the translation frame. When the distance between the translation frame and the positioning frame is adapted to the width of the cabinet plate to be welded, the welding of cabinet plates of different widths can be realized, thereby realizing the production of control cabinets of different specifications.

[0021] Please see Figure 1 - Figure 12An auxiliary laser welding device for control cabinet housing production includes a welding device 1, which is a laser welding device. A fixed column 2 is provided above the center of the welding device 1. Two rotating flaps 5 and 6 are respectively provided on both sides of the fixed column 2. The inner surfaces of the flaps 5 and 6 are placed with cabinet panels 7 to be welded. The cabinet panels 7 are conventional cabinet panels in the prior art. An angle iron limiting frame 8 is fixedly installed on the surface of the fixed column 2 to limit the docking of the flaps 5 and 6. The angle iron limiting frame 8 enables the two cabinet panels 7 to dock quickly. A movable frame 9 is provided above the fixed column 2, and a centering frame 10 is provided below the movable frame 9. A telescopic device 12 is fixedly installed on the bottom center of the 10. The telescopic device 12 is a conventional electrically controlled push rod in the prior art. A fixed frame 13 is fixedly installed on the telescopic end of the telescopic device 12. A laser welder 14 is fixedly installed on the bottom center of the fixed frame 13. The laser welder 14 is a conventional laser welder in the prior art. Two sliding grooves 15 are correspondingly opened on the bottom surface of the fixed frame 13. The interior of each sliding groove 15 is slidably connected to a matching slider 16. A connecting frame 22 is fixedly installed on the bottom surface of each slider 16. Rotating plates 17 and 18 are rotatably connected to the inner sides of the two connecting frames 22 respectively. The rotation of rotating plates 17 and 18 forms the same angle as the two box plates 7. The "V"-shaped plate is rotatably connected between rotating plate 17 and rotating plate 28. Both rotating plate 17 and rotating plate 28 have annular grooves 20 on their surfaces, and multiple air jet pipes 21 are fixedly installed inside each annular groove 20. Compared to traditional welding equipment 1, this welding equipment 1, during operation, places two box plates 7 to be welded on the surfaces of rotating plates 15 and 26. Rotating plates 15 and 26 rotate towards each other around the surface of the fixed column 2. When the included angle between the two box plates 7 after rotation is 90 degrees, the two box plates 7 move under their own weight, causing the bottom surfaces of the two box plates 7 to contact the surface of the angle iron limit frame 8. At this point, the two box plates 7 are joined together without manual intervention. The angle adjustment and fixing of the plates to be welded improves the docking speed of the welding equipment 1 to the box plate 7, thereby improving the welding efficiency of the welding equipment 1 to the box plate 7. The centering frame 10 moves downward and first contacts the surfaces of the two box plates 7. When the ball bearing 11 at one end of the centering frame 10 contacts the surface of the box plate 7, as the telescopic device 26 extends, the centering frame 10 moves towards the other ball bearing 11. When both ends of the centering frame 10 contact the surfaces of the two box plates 7 at the same time, the centering frame 10 carries the laser welder 14 to the center and aligns it with the welding position, realizing that the laser welder 14 can quickly align with the welding position of the two box plates 7, further improving the welding efficiency of the laser welder 14 to the two box plates 7.The surfaces of the two box-shaped plates 7 simultaneously press against the two connecting frames 22, causing them to move in opposite directions. This causes rotating plates 17 and 18 to rotate simultaneously. When rotating plates 17 and 18 rotate at the same angle to the two box-shaped plates 7, multiple air jets 21 on both sides also move with the plates, adjusting their angles to align with the weld joint of the two box-shaped plates 7. This rapid alignment of the air jets 21 with the weld joint ensures the welding quality of the box-shaped plates 7 by the laser welder 14.

[0030] Both flip-plate 5 and flip-plate 6 have through slots 46 on their surfaces. A matching limiting frame 47 is slidably connected inside each slot 46. A translation frame 48 is fixedly installed on the inner side of the limiting frame 47. Positioning frames 49 are fixedly installed on the inner sides of both flip-plate 5 and flip-plate 6. A rotating wheel 50 is rotatably connected to the inner side of both the positioning frame 49 and the translation frame 48. Connecting blocks 51 are fixedly installed on the outer surfaces of both flip-plate 5 and flip-plate 6. A through threaded rod 52 is threaded onto the surface of the connecting block 51. The limiting frame 47... A rotating base 53 is fixedly installed on the surface of 7. One end of the threaded rod 52 is rotatably connected to the rotating base 53. According to the width of the box plate 7 to be welded, the threaded rod 52 is manually rotated. Under the action of the rotation of the threaded rod 52, the limiting frame 47 moves inside the slot 46. The movement of the limiting frame 47 moves the translation frame 48. When the distance between the translation frame 48 and the positioning frame 49 is adapted to the width of the box plate 7 to be welded, the welding of box plates 7 of different widths can be realized, thereby realizing the production of control cabinet boxes of different specifications.

[0031] The usage steps of this invention are as follows: When using this auxiliary laser welding device for control cabinet production, initially, the bottom surfaces of flip plate 5 and flip plate 6 are in contact with the surfaces of the two limiting plates 31, and flip plate 5 and flip plate 6 are parallel to the surface of the welding equipment 1. First, according to the width of the cabinet plate 7 to be welded, manually rotate the threaded rod 52. The rotation of the threaded rod 52 causes the limiting frame 47 to move inside the slot 46. The movement of the limiting frame 47 moves the translation frame 48. When the distance between the translation frame 48 and the positioning frame 49 is adapted to the width of the cabinet plate 7 to be welded, stop rotating the threaded rod 52. At this time, place the two cabinet plates 7 to be welded on the surfaces of flip plate 5 and flip plate 6, and push the two cabinet plates 7 so that they move towards each other. At this time, the cabinet plates 7... The two sides move within the rotating wheel 50. After the box plate 7 is placed, the controller 45 is operated. The controller 45 controls the two telescopic devices 35 to extend. The telescopic devices 35 extend and move the movable seat 33 inside the movable slot 32, thereby causing the flip plate 1 5 and flip plate 2 6 to rotate towards each other around the surface of the fixed column 2. When the angle between the two box plates 7 after they rotate towards each other is 90 degrees (in order to detect the angle between the two box plates 7, an angle sensor can be installed on the inner side of the vertical frame 36 for detection. The angle sensor is existing technology and is not shown in the figure), the telescopic device 35 stops working. During the rotation of the flip plate 1 5 and flip plate 2 6 towards each other, the two box plates 7 move under their own weight, thereby causing the bottom surface of the two box plates 7 to contact the surface of the angle iron limit frame 8. Figure 8As shown), at this point, the two box panels 7 are joined together. Then, the telescopic device 26 extends, moving the movable frame 9 and the centering frame 10 downwards. The centering frame 10 first contacts the surfaces of the two box panels 7. When the ball bearing 11 at one end of the centering frame 10 contacts the surface of the box panel 7, as the telescopic device 26 extends, one of the ball bearings 11 is compressed and moves, causing the centering frame 10 to move towards the other ball bearing 11. The movement of the centering frame 10 causes the movable block 28 to move inside the slot 27. When the centering... When both ends of the frame 10 simultaneously contact the surfaces of the two box panels 7, since the laser welder 14 is located below the center of the frame 10, the frame 10, carrying the laser welder 14, is aligned with the welding position and the telescopic device 26 stops moving. The telescopic device 12 extends and moves the fixed frame 13 downwards. The movement of the fixed frame 13 moves the two connecting frames 22 downwards. When the two ball bearings 19 on both sides simultaneously contact the surfaces of the two box panels 7, as the telescopic device 12 continues to extend, the surfaces of the two box panels 7 are simultaneously squeezed. The two connecting frames 22 move in opposite directions, causing the two sliders 16 to move in opposite directions as well, stretching the spring 25. During the movement of the two connecting frames 22, the rotating plates 17 and 18 rotate simultaneously. When the angle between the rotating plates 17 and 18 and the two box plates 7 is the same, the telescopic device 12 is notified to move. During the rotation of the rotating plates 17 and 18, multiple air jets 21 on both sides also move with the rotating plates 17 and 18 to adjust their angles, so that the angles of the two sides are adjusted. Multiple jet pipes 21 are aligned with the weld joint of the two box plates 7. Then, the motor 43 rotates, causing the lead screw 42 to rotate, which makes the reciprocating block 41 move in the lower connecting groove 40, thereby carrying the laser welder 14 to weld along the joint of the two box plates 7. While the laser welder 14 is working, the air pump 37 works to extract the protective gas for welding and supply it to the multiple jet pipes 21. During the welding process of the laser welder 14 on the joint of the two box plates 7, the multiple jet pipes 21 blow air into the joint during welding.

[0032] Compared to traditional welding equipment 1, this welding equipment 1, during operation, places two box-shaped plates 7 to be welded on the surfaces of flip plates 5 and 6. Flip plates 5 and 6 rotate towards each other around the surface of the fixed column 2. When the angle between the two box-shaped plates 7 after rotation is 90 degrees, the two box-shaped plates 7 move under their own weight, causing the bottom surfaces of the two box-shaped plates 7 to contact the surface of the angle iron limiting frame 8. At this point, the two box-shaped plates 7 are joined together, without the need for manual intervention to adjust the angle and fix the plates to be welded, thus improving the joining speed of the welding equipment 1 on the box-shaped plates 7 and thereby improving the welding efficiency of the welding equipment 1 on the box-shaped plates 7. The centering frame 10 moves downward and first contacts the surfaces of the two box-shaped plates 7. When the ball bearing 11 at one end of the centering frame 10 contacts the surface of the box-shaped plate 7, as the telescopic device 26 extends, the centering frame 10 moves towards the other ball bearing 11. When both ends of the centering frame 10... When the laser welding device 14 simultaneously contacts the surfaces of the two box panels 7, the centering frame 10, carrying the laser welding device 14, is aligned with the welding position, enabling the laser welding device 14 to quickly align with the welding position of the two box panels 7, further improving the welding efficiency of the laser welding device 14 on the two box panels 7. The surfaces of the two box panels 7 simultaneously press against the two connecting frames 22, causing the rotating plates 17 and 28 to rotate simultaneously. When the rotating plates 17 and 28 rotate at the same angle as the two box panels 7, the multiple air jets 21 on both sides also follow the rotation of the rotating plates 17 and 28 to adjust their angles, so that the multiple air jets 21 on both sides are aligned with the butt weld of the two box panels 7, enabling the air jets 21 to quickly align with the butt weld of the two box panels 7, ensuring the welding quality of the box panels 7 by the laser welding device 14.
