Description

Technical Field

[0001] This invention relates to the field of welding facilities, specifically to a welding device for a power distribution cabinet. Background Technology

[0002] Distribution cabinets are indispensable core equipment in power systems, typically composed of components such as cabinets, circuit breakers, fuses, and instrument transformers. Distribution cabinets enable centralized reception, distribution, control, and monitoring of electrical energy, and quickly cut off power in the event of overload, short circuit, or leakage faults to protect electrical equipment and personnel.

[0003] In the manufacturing process of electrical distribution cabinets, after the metal plate is bent into a rectangular structure, the two ends of the metal plate are usually welded together using welding equipment to initially form the cabinet outline. However, during the actual welding operation, due to the residual stress generated during the bending process of the metal plate, gaps will appear at the ends of the rectangular metal plate, which cannot close naturally. At this time, workers need to manually adjust the position of the joint ends until the two ends are completely closed before fixing them, and only then can welding work be carried out. This process is quite cumbersome and causes inconvenience in welding. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a welding device for a power distribution cabinet.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding device for a power distribution cabinet, comprising a welding base, a corner shell fixedly installed on the upper end of the welding base, two concave seats symmetrically and obliquely arranged on the upper sides of the corner shell, the two concave seats being fixed to the welding base, a servo push cylinder fixedly installed on the upper end of the welding base away from the rear of the corner shell, a main pressure frame fixedly installed at the output end of the servo push cylinder, two pressure plates symmetrically and obliquely installed at both ends of the main pressure frame, the pressure plates being located above the concave seats, the pressure plates being in the opposite direction of inclination to the concave seats, a secondary pressure frame elastically installed on the lower end of the main pressure frame, a lower triangular ridge fixedly installed on the lower end of the secondary pressure frame, the lower triangular ridge being located above the corner shell, welding parts installed on the side of the welding base, and a fixing part arranged on the upper end of the welding base near the rear of the corner shell.

[0008] Preferably, a gear is rotatably mounted on the front end of the upright frame, a lower toothed plate is meshed on one side of the gear, the end of the lower toothed plate is fixed to the auxiliary pressure frame, an upper toothed plate is meshed on the other side of the gear, a slide is fixedly mounted on the end of the upper toothed plate, the end of the slide is slidably mounted on the outer surface of the upright frame, an upper triangular ridge is fixedly mounted on the upper end of the slide, the upper triangular ridge is located above the lower triangular ridge, and the corner bracket is located above the upper triangular ridge.

[0009] Preferably, guide rods are slidably installed on both sides of the carrier frame, the lower end of the guide rods is fixed to the upright frame, and a No. 3 return spring is wound around the outside of the guide rods. The two ends of the No. 3 return spring are respectively fixed to the upper end of the upright frame and the lower end of the carrier frame.

[0010] Preferably, a limiting rod is slidably mounted through the rear end of the carrier, the front end of the limiting rod is fixed to the slider, and a first return spring is wound around the outside of the limiting rod. The two ends of the first return spring are respectively fixed to the rear end of the slider and the inner rear end of the carrier.

[0011] Preferably, the welding component includes a push slide fixedly installed on the side of the welding seat, a push plate slidably installed on the side of the push slide, a lifting plate slidably installed on the side of the push plate, a gun holder fixedly installed at the middle of the side of the lifting plate, a welding gun fixedly installed at the end of the gun holder, a fixed seat fixedly installed at the edge of the side of the lifting plate, a pressure roller installed at the lower end of the fixed seat, the pressure roller pressing on the carrier, and a lever ear fixedly installed at the front end of the fixed seat, the end of the lever ear being located in front of the slider.

[0012] Preferably, a push threaded rod is rotatably mounted on the middle of the side of the push slide, and the push slide plate is screwed to the outer surface of the push threaded rod. A first servo motor is fixedly mounted on the side edge of the push slide, and the output end of the first servo motor is fixed to the push threaded rod. A lifting threaded rod is rotatably mounted on the middle of the side of the push slide plate, and the lifting slide plate is screwed to the outer surface of the lifting threaded rod. A second servo motor is fixedly mounted on the side edge of the push slide plate, and the output end of the second servo motor is fixed to the lifting threaded rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Place the opposite corner of the cabinet shell and the welding point into the corner shell. Then, the servo push cylinder operates to drive the lower triangular edge and pressure plate downward. The lower triangular edge presses down on the opposite corner of the welding point from the inside of the cabinet shell, forcing it into the corner shell for restraint. The servo push cylinder then continues to drive the pressure plate downward, moving it to the concave seat. The concave seat and pressure plate restrain the corners on both sides of the cabinet shell, thereby applying a binding force to the corners of the cabinet shell, i.e., the bending points, to counteract the interference of bending stress. This allows the two mating ends of the cabinet shell to close together for welding. The process does not require manual closing by the worker, effectively facilitating the welding process.

[0015] 2. When the servo push cylinder moves the lower triangular edge downwards, the downward-moving lower triangular edge will drive the gear to rotate through the lower gear plate, thereby driving the upper gear plate to move upwards, thus moving the upper triangular edge to the height of the docking end of the cabinet. When the lifting slide moves the welding gun downwards for welding, the fixed seat will move downwards simultaneously and apply pressure to the carrier, causing the corner bracket and fixed plate on the carrier to move downwards to apply pressure from the outside of the docking end of the cabinet. This clamps the two docking ends of the closed cabinet between the upper triangular edge and the corner bracket and fixed plate, thereby aligning the two docking ends of the cabinet vertically and avoiding the welding quality affected by the vertical misalignment of the two docking ends, thus ensuring the welding quality.

[0016] 3. When the sliding plate moves the welding gun backward for welding, the fixed seat will slide along the carrier and move backward synchronously. During this process, the lever ear on the fixed seat will move the slider, thereby driving the corner frame to slide backward. This allows the corner frame to gradually move backward during the welding process, exposing the joints of the two mating ends of the cabinet for welding. This ensures that the welding gun will not be obstructed by the corner frame during the welding process. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a technical solution: such as Figures 1-10The welding device for a distribution cabinet shown includes a welding base 1. A corner shell 2 is fixedly installed on the upper end of the welding base 1. Two concave seats 5 are symmetrically and obliquely arranged on the upper sides of the corner shell 2. The front and rear edges of the corner shell 2 and the concave seats 5 can fit against the front and rear end faces of the cabinet shell 37 to limit the front and rear positions of the cabinet shell 37. The two concave seats 5 are fixed to the welding base 1. A servo push cylinder 25 is fixedly installed on the upper end of the welding base 1 away from the rear of the corner shell 2. A main pressure frame 7 is fixedly installed at the output end of the servo push cylinder 25. Two pressure plates 6 are symmetrically and obliquely installed at both ends of the main pressure frame 7. The main pressure frame 7 drives the pressure plates 6 to move downward. The pressure plates 6 are located above the concave seats 5. The oblique direction of the pressure plates 6 and the concave seats 5 is opposite, which can adapt to the side corners of the cabinet shell 37 for limiting. A secondary pressure frame 4 is elastically installed at the lower end of the main pressure frame 7. A lower triangular ridge is fixedly installed at the lower end of the secondary pressure frame 4. 3. The auxiliary pressure frame 4 can drive the lower triangular edge 3 to move down under the drive of the main pressure frame 7. The lower triangular edge 3 is located above the corner shell 2. Welding parts are installed on the side of the welding seat 1. A fixing part is set at the upper end of the welding seat 1 near the rear of the corner shell 2. The servo push cylinder 25 works to drive the lower triangular edge 3 and the pressure plate 6 to move down. The lower triangular edge 3 is used to press the corner opposite to the welding point from the inside of the cabinet shell 37, so that it is pressed into the corner shell 2 for restriction. Then the servo push cylinder 25 continues to drive the pressure plate 6 to move down to the concave seat 5. The concave seat 5 and the pressure plate 6 are used to restrict the corners on both sides of the cabinet shell 37, thereby applying a binding force to the corners of the cabinet shell 37, i.e. the bending point, to counteract the interference of bending stress, so that the two mating ends of the cabinet shell 37 can be closed together for welding. The process does not require manual closing by the worker, which effectively facilitates welding.

[0030] Two guide posts 27 are symmetrically fixedly installed on the upper rear part of the auxiliary pressure frame 4. The main pressure frame 7 is slidably installed on the outer surface of the two guide posts 27. The guide posts 27 serve to guide the auxiliary pressure frame 4. A second return spring 26 is wound around the outside of the guide posts 27. The two ends of the second return spring 26 are fixed to the upper end of the auxiliary pressure frame 4 and the lower end of the main pressure frame 7, respectively. When the lower triangular edge 3 presses the corner opposite to the welding point from the inside of the cabinet shell 37, and presses it into the corner shell 2, the lower triangular edge 3 will remain stationary, that is, remain in the pressing state. Then, when the servo push cylinder 25 continues to drive the pressure plate 6 to move down, the second return spring 26 will deform, allowing the pressure plate 6 to move down normally.

[0031] The fasteners include a support frame 21 fixedly installed on the upper end of the welding base 1 near the rear of the corner shell 2. The support frame 21 provides support. The auxiliary pressure frame 4 passes through the lower part of the support frame 21. A carrier frame 11 is elastically installed on the upper end of the support frame 21. Two fixing plates 13 are symmetrically and obliquely installed on the lower front part of the carrier frame 11. A slider 14 is slidably installed inside the carrier frame 11. The carrier frame 11 supports the fixing plates 13 and provides a sliding surface for the slider 14. An angle bracket 12 is fixedly installed on the lower end of the slider 14. The two ends of the angle bracket 12 are respectively attached to the two fixing plates 13. The lower end surfaces of the two fixing plates 13 are coplanar with the inner surface of the angle bracket 12, which can ensure that the fixing plates 13 and the angle bracket 12 can be attached to the outer side of the mating end of the cabinet shell 37.

[0032] A gear 17 is rotatably mounted on the front end of the upright frame 21. A lower toothed plate 9 meshes with one side of the gear 17, and the end of the lower toothed plate 9 is fixed to the auxiliary pressure frame 4. An upper toothed plate 8 meshes with the other side of the gear 17. The gear 17 connects the lower toothed plate 9 and the upper toothed plate 8. A slide 18 is fixedly mounted on the end of the upper toothed plate 8, and the end of the slide 18 is slidably mounted on the outer surface of the upright frame 21. An upper triangular ridge 19 is fixedly mounted on the upper end of the slide 18, and the slide 18 guides the upper triangular ridge 19. The lower triangular ridge 3 moves downwards... The lower gear plate 9 drives the gear 17 to rotate, which in turn drives the upper gear plate 8 to move upward, thereby moving the upper triangular ridge 19 to the height of the mating end of the cabinet shell 37. The upper triangular ridge 19 is located above the lower triangular ridge 3, and the corner bracket 12 is located above the upper triangular ridge 19. The corner bracket 12 and the fixing plate 13 on the carrier 11 move downward to apply pressure from the outside of the mating end of the cabinet shell 37, so that the two mating ends of the closed cabinet shell 37 are clamped between the upper triangular ridge 19 and the corner bracket 12 and the fixing plate 13, thereby aligning the two mating ends of the cabinet shell 37 vertically.

[0033] Guide rods 20 are slidably installed on both sides of the carrier 11. The lower end of the guide rod 20 is fixed to the upright frame 21. The guide rod 20 serves to slide the carrier 11. A No. 3 return spring 36 is wound around the outside of the guide rod 20. The two ends of the No. 3 return spring 36 are fixed to the upper end of the upright frame 21 and the lower end of the carrier 11, respectively. The No. 3 return spring 36 serves to drive the carrier 11, which has moved downward, to move upward and return to its original position.

[0034] A limiting rod 15 is slidably mounted through the rear end of the carrier 11. The front end of the limiting rod 15 is fixed to the slider 14. A first return spring 16 is wound around the outside of the limiting rod 15. The limiting rod 15 prevents the first return spring 16 from bending. The two ends of the first return spring 16 are fixed to the rear end of the slider 14 and the inner rear end of the carrier 11, respectively. The first return spring 16 drives the slider 14, which has moved backward, to move forward and return to its original position.

[0035] The welding component includes a push slide 24 fixedly mounted on the side of the welding base 1. A push slide plate 30 is slidably mounted on the side of the push slide 24, serving to allow the push slide plate 30 to slide. A lifting slide plate 33 is slidably mounted on the side of the push slide plate 30, serving to allow the lifting slide plate 33 to slide. A gun holder 34 is fixedly mounted on the middle of the side of the lifting slide plate 33, and a welding gun 35 is fixedly mounted on the end of the gun holder 34, serving to fix the welding gun 35. The welding gun 35 is connected to an external welding machine for welding operations. Since welding with a welding gun 35 is existing technology and has been widely used, it is not described in detail here. A fixing seat 10 is fixedly mounted on the side edge of the lifting slide plate 33, and the lower end of the fixing seat 10 is fitted with... The pressure roller 23 is installed on the carrier frame 11. When the lifting slide plate 33 moves the welding gun 35 down, the fixed seat 10 moves down synchronously and applies pressure to the carrier frame 11, causing the corner bracket 12 and fixed plate 13 on the carrier frame 11 to move down. When the fixed seat 10 moves on the carrier frame 11, the pressure roller 23 will roll to reduce the friction between the two. The front end of the fixed seat 10 is fixedly installed with a lever ear 22. The end of the lever ear 22 is located in front of the slider 14. The lever ear 22 on the fixed seat 10 will move the slider 14, thereby causing the corner bracket 12 to slide backward. During the welding process, the corner bracket 12 can gradually move backward to expose the joint of the two mating ends of the cabinet shell 37 for welding, thus ensuring that the welding gun 35 is not obstructed by the corner bracket 12 during the welding process.

[0036] A threaded rod 28 is rotatably mounted on the middle of the side of the push slide 24. The push slide plate 30 is screwed onto the outer surface of the threaded rod 28. The threaded rod 28 drives the push slide plate 30 to move. A first servo motor 29 is fixedly mounted on the side edge of the push slide 24. The output end of the first servo motor 29 is fixed to the threaded rod 28. The first servo motor 29 drives the threaded rod 28 to rotate. A lifting threaded rod 32 is rotatably mounted on the middle of the side of the push slide plate 30. The lifting slide plate 33 is screwed onto the outer surface of the lifting threaded rod 32. The lifting threaded rod 32 drives the lifting slide plate 33 to move. A second servo motor 31 is fixedly mounted on the side edge of the push slide plate 30. The output end of the second servo motor 31 is fixed to the lifting threaded rod 32. The second servo motor 31 drives the lifting threaded rod 32 to rotate.

[0037] During welding, the opposite corner of the cabinet shell 37 is placed inside the corner shell 2. Then, the servo push cylinder 25 operates to move the lower triangular ridge 3 and the pressure plate 6 downwards. The lower triangular ridge 3 presses down on the opposite corner of the cabinet shell 37 from the inside, forcing it into the corner shell 2 for restraint. The servo push cylinder 25 then continues to move the pressure plate 6 downwards until it reaches the concave seat 5. The concave seat 5 and the pressure plate 6 then restrain the corners on both sides of the cabinet shell 37, thereby applying pressure to the corners of the cabinet shell 37, i.e., the bent areas. The binding force counteracts the interference of bending stress, allowing the two mating ends of the cabinet shell 37 to close together. During the above process, when the servo push cylinder 25 moves the lower triangular edge 3 downward, the downward-moving lower triangular edge 3 will drive the gear 17 to rotate via the lower gear plate 9, thereby driving the upper gear plate 8 to move upward, thus driving the upper triangular edge 19 to the height of the mating end of the cabinet shell 37. Subsequently, the second servo motor 31 drives the lifting threaded rod 32 to rotate, thereby driving the lifting slide plate 33 to slide downward on the push slide plate 30, thereby driving the welding torch 35. As the lifting slide plate 33 moves the welding torch 35 down to the required welding height, the fixed base 10 moves down synchronously, applying pressure to the carrier frame 11. This causes the corner bracket 12 and fixed plate 13 on the carrier frame 11 to move down, applying pressure from the outside of the mating ends of the cabinet shell 37. This clamps the two mating ends of the closed cabinet shell 37 between the upper triangular ridge 19 and the corner bracket 12 and fixed plate 13, thus aligning the two mating ends of the cabinet shell 37 vertically. Subsequently, the first servo motor 29 drives the push threaded rod 28 to rotate, thereby driving the push slide plate 30 to... The slide block 24 is pushed to move backward, allowing the welding torch 35 to move above the mating end of the cabinet shell 37 for welding. During this process, the fixed seat 10 slides along the carrier 11 and moves backward synchronously. The lever ear 22 on the fixed seat 10 will move the slider 14, thereby driving the corner bracket 12 to slide backward. During the welding process, the corner bracket 12 can gradually move backward, exposing the joint of the two mating ends of the cabinet shell 37 for welding. This ensures that the welding torch 35 is not obstructed by the corner bracket 12 during the welding process.
