Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically an arc welding device for processing high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is a core component of power systems, responsible for power distribution, control, and cable connection. Its housing is typically welded from multiple metal plates, and the welding quality directly determines the switchgear's structural strength, sealing performance, and operational safety, thus affecting the stable operation of the entire power system. With the continuous advancement of national infrastructure construction and investment in power energy, the market demand for high and low voltage switchgear is increasing year by year, and the pace of product upgrades is accelerating. This has led to increasingly higher requirements for switchgear processing efficiency and welding precision. As a core process for connecting switchgear plates, the performance of the processing equipment for arc welding directly restricts the production quality and delivery efficiency of the switchgear.

[0003] Currently, the arc welding of high and low voltage switchgear panels mostly adopts traditional methods. During processing, multiple panels that make up the top, bottom, and side walls of the switchgear must first be transported to designated locations. The relative positions of each panel are manually aligned to ensure edge alignment. Then, additional tooling fixtures are used to clamp and fix the panels to prevent displacement during welding. After fixing, the operator operates the welding equipment to perform arc welding on the joints of each panel one by one. In some scenarios, simple welding fixtures are also used to assist in positioning and complete the forming of the cabinet frame.

[0004] The existing welding processing methods have obvious technical defects and are difficult to meet the needs of large-scale, high-precision production: the plate positioning process relies on manual calibration, which is slow and has low accuracy, and is prone to edge alignment deviation. After positioning, in order to avoid the positioning mechanism from affecting the welding work, the positioning structure needs to be separated from the plate. Before welding, the tooling fixtures need to be set up, calibrated and disassembled separately, which increases the welding preparation process, prolongs the overall processing time and results in low welding efficiency.

[0005] Therefore, it is necessary to provide an arc welding device for processing high and low voltage switchgear to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an arc welding device for processing high and low voltage switchgear. Through the coordinated arrangement of a welding table, four welding mechanisms, a support plate and a positioning mechanism, combined with the cooperation of a drive component and an adsorption and fixing component, it effectively solves the technical problems in the prior art, such as reliance on manual positioning of sheet metal, low accuracy and slow speed, and the need to build additional tooling fixtures, which leads to cumbersome welding preparation procedures and low efficiency.

The bottom end of the transmission rod is fixedly connected to the second slider, the transmission rod passes through the first slider, and the transmission rod is slidably engaged with the first slider. The top end of the transmission rod is fixedly connected to the transmission plate.

[0013] A further feature of the present invention is that a hydraulic cylinder is fixedly installed on the support plate, the output end of the hydraulic cylinder passes through the support plate, and the output end of the hydraulic cylinder is fixedly connected to the adjusting plate.

[0021] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please see Figures 1-10 In this embodiment of the invention, an arc welding device for processing high and low voltage switchgear includes a welding table 1, four welding mechanisms 2 disposed at the four corners of the welding table 1, four support plates 3 disposed on the four sides of the welding table 1, and four positioning mechanisms 4 disposed on the four sides of the support plates 3. Each of the four support plates 3 is topped with a second support plate 18, which is equipped with an adsorption and fixing component for adsorbing and fixing the plates. The welding table 1 is equipped with multiple driving components for driving the second support plates 18 to rotate. During processing, the four plates constituting the top wall, bottom wall, and two opposite side walls of the switchgear are first placed on the bearing surfaces of the four second support plates 18, and then the four positioning mechanisms 4... The four plates are precisely positioned using a synergistic effect, ensuring that the edge alignment accuracy of each plate meets the welding process requirements. After positioning, the adsorption and fixing components are activated to stably adsorb and fix the plates, preventing displacement or shaking during subsequent rotation and welding. Next, the support plate 18 is driven by the drive components to rotate smoothly from a horizontal position to a vertical position, so that the four plates respectively form the top wall, bottom wall and two opposite side walls of the switch cabinet, and the joints of each plate are precisely aligned to form a complete cabinet frame. Finally, the four welding mechanisms 2 are activated to perform synchronous or step-by-step arc welding operations on the joints of each plate, thereby quickly achieving the integrated welding of the top wall, bottom wall and two opposite side walls of the switch cabinet.

[0023] The beneficial effects of this device are as follows: the positioning process of the four plates does not require manual calibration, the positioning speed is fast and the accuracy is high. After positioning, the plates can be quickly rotated to the preset welding position by the drive component. There is no need to use additional tooling fixtures to position and fix the plates before welding, which effectively reduces the process of tooling assembly, disassembly and calibration, shortens the welding preparation time, and significantly improves the welding efficiency of switchgear plates. At the same time, the integrated positioning, fixing and rotating structure ensures the docking accuracy of the plate connections, reduces welding deviation, improves the quality stability of switchgear welding, reduces subsequent rework costs, and is adaptable to the welding needs of different specifications of plates in high and low voltage switchgear, making it highly practical.

[0024] In this embodiment, preferably, the positioning mechanism 4 includes a vertical plate 401, a mounting base 402 fixedly installed on one side of the top of the vertical plate 401, and a positioning plate 405 disposed on one side of the mounting base 402. The positioning plate 405 is elastically connected to the mounting base 402 through an elastic connecting assembly. An adjusting plate 9 is disposed below the support plate 3, and transmission assemblies 5 for driving the positioning plate 405 to move are disposed on all four sides of the adjusting plate 9. The elastic connecting assembly includes a support cylinder 403, a sliding column 404, and a spring 406. One end of the support cylinder 403 is fixedly connected to the mounting base 402, and the sliding column 404 is slidably engaged with the support cylinder 403. One end of the sliding column 404 extends into the support cylinder 403, and the sliding column 404 is elastically connected to the inner wall of the support cylinder 403 through the spring 406. The other end of the sliding column 404 is fixedly connected to the positioning plate 405. A transmission plate 408 is slidably disposed on the side of the vertical plate 401 away from the support plate 3, and a fixed transmission plate 408 is mounted on the transmission plate 408. A traction rope 407 is connected, with the side of the traction rope 407 away from the transmission plate 408 extending into the support cylinder 403 and fixedly connected to the sliding column 404. Its working principle is as follows: the transmission assembly 5 drives the transmission plate 408 to slide up and down along the vertical plate 401. When the transmission plate 408 moves downward, it pulls the traction rope 407 downward simultaneously. The traction rope 407, through tension, drives the sliding column 404 to slide along the support cylinder 403 towards the vertical plate 401, thereby driving the positioning plate 405 to move synchronously towards the vertical plate 401, achieving the retraction of the positioning plate 405. When the transmission plate 408 moves upward, the traction rope 407 gradually loosens, losing its tension constraint. Under the elastic reset action of the spring 406, the sliding column 404 slides along the support cylinder 403 away from the vertical plate 401, thereby driving the positioning plate 405 to move synchronously away from the vertical plate 401, achieving the extension of the positioning plate 405, thus completing the flexible adjustment of the position of the positioning plate 405.

[0025] The specific operational logic for positioning the board is as follows: First, the transmission component 5 drives the four positioning plates 405 to retract synchronously and move away from each other, leaving sufficient space for the board to be placed. Then, the board is placed stably on the support plate 18, with the board approximately centered among the four positioning plates 405. Next, the transmission component 5 drives the four positioning plates 405 to extend synchronously and move closer to each other, using the thrust of the positioning plates 405 to move the board until the four positioning plates 405 are tightly fitted with the four side walls of the board, achieving precise positioning of the board and ensuring that the board does not shift its position during subsequent adsorption, fixation, and rotation. The beneficial effects of this positioning mechanism 4 are: the use of elastic connecting components and the transmission component 5 to work together to achieve automatic extension and retraction adjustment of the positioning plates 405, making the positioning operation convenient and efficient, without the need for manual adjustment of the position of the positioning plates 405.

[0026] In this embodiment, preferably, guide posts 6 are fixedly installed on all four side walls of the support plate 3, and slider 7 is fixedly installed on the lower surface of the upright plate 401. The guide posts 6 pass through the slider 7, and the slider 7 slides with the guide posts 6. The upright plate 401 is fixedly installed on the slider 7, and a locking knob 8 for locking the slider 7 is provided on the slider 7. The locking knob 8, together with the bolt locking structure, locks the slider 7. By setting the slider 7, the position of the positioning mechanism 4 can be adjusted to adapt to different sizes of plates. After the position of the slider 7 is adjusted, the slider 7 is locked by tightening the locking knob 8. Its beneficial effects are as follows: The sliding cooperation between slider 7 and guide post 6 enables the positioning mechanism 4 to move flexibly along the side of support plate 3. The spacing of the positioning mechanism 4 can be precisely adjusted according to the different sizes of switch cabinet plates, which greatly improves the adaptability of the device. There is no need to equip plates of different sizes with special positioning mechanisms 4, which reduces the equipment investment cost. The cooperation between locking knob 8 and bolt locking structure can achieve the firm locking of slider 7 after the position of positioning mechanism 4 is adjusted, preventing slider 7 from sliding and causing the position of positioning mechanism 4 to shift during subsequent positioning and welding processes, ensuring the stability of positioning accuracy. At the same time, the locking operation is simple and convenient, making it easy for operators to quickly complete the adjustment and locking operations.

[0027] In this embodiment, preferably, the transmission assembly 5 includes a second guide post 501, a second slider 502, and a transmission rod 503. The second guide post 501 is fixedly connected to the side wall of the adjusting plate 9, the second guide post 501 passes through the second slider 502, and the second slider 502 is slidably engaged with the second guide post 501. The bottom end of the transmission rod 503 is fixedly connected to the second slider 502, the transmission rod 503 passes through the first slider 7, and the transmission rod 503 is slidably engaged with the first slider 7. The top end of the transmission rod 503 is fixedly connected to the transmission plate 408. Its working principle is as follows: through the lifting and lowering movement of the adjusting plate 9, multiple second guide posts 501 can be simultaneously driven to lift and lower. When the second guide post 501 lifts and lowers, it will drive the transmission rod 503 to lift and lower synchronously through the second slider 502, thereby driving the transmission plate 408, which is fixedly connected to the top end of the transmission rod 503, to slide up and down along the vertical plate 401. This realizes that the transmission assembly 5 drives the transmission plate 408 to lift and lower, providing stable power for the extension and retraction adjustment of the positioning plate 405. The design of 02 allows slider 502 to adaptively slide along guide post 501 when slider 7 slides along guide post 6 to adjust the position of positioning mechanism 4. This ensures that transmission rod 503 remains stably connected to transmission plate 408, preventing problems such as jamming or transmission failure of transmission component 5 due to position adjustment of positioning mechanism 4, and guaranteeing stable transmission of power. The beneficial effects of this transmission component 5 are: the sliding cooperation structure of guide post and slider results in low transmission resistance and smooth movement, enabling uniform lifting and lowering of transmission plate 408, which in turn drives positioning plate 405 to move at a uniform speed, avoiding impact on the plate due to excessive movement speed of positioning plate 405; the synchronous linkage of multiple transmission components 5 enables synchronous adjustment of multiple positioning plates 405, ensuring uniform force during plate positioning and further improving positioning accuracy; the adaptive sliding design of slider 502 ensures that the position adjustment of positioning mechanism 4 and power transmission of transmission component 5 do not interfere with each other, improving the overall operational stability and ease of operation of the device.

[0028] In this embodiment, preferably, a hydraulic cylinder 10 is fixedly installed on the support plate 3. The output end of the hydraulic cylinder 10 passes through the support plate 3 and is fixedly connected to the adjusting plate 9. Its working principle is as follows: the extension and retraction of the output end of the hydraulic cylinder 10 can directly drive the adjusting plate 9 to move up and down. When the adjusting plate 9 moves, it will simultaneously drive multiple guide posts 501 to rise and fall. The guide posts 501 drive the transmission rod 503 to rise and fall through the slider 502, thereby driving multiple transmission plates 408 to rise and fall synchronously, and finally realizing the synchronous position adjustment of multiple positioning plates 405. The beneficial effects of this structure are as follows: Using a single hydraulic cylinder 10 as the power source, in conjunction with the linkage of the adjusting plate 9, multiple transmission components 5 can be driven synchronously to achieve synchronous and equidistant movement of multiple positioning plates 405. This ensures consistent positioning accuracy for the four plates, avoiding plate positioning deviations caused by adjustments of a single positioning plate 405, thus improving positioning accuracy and consistency. The power output of the hydraulic cylinder 10 is stable and controllable. By adjusting the extension and retraction stroke of the hydraulic cylinder 10, the movement distance of the positioning plate 405 can be precisely controlled, adapting to the positioning requirements of plates of different sizes. Furthermore, the hydraulic cylinder 10 has high operational reliability and a long service life, reducing the maintenance costs of the device. The single power source simplifies the structural design of the device, reduces the investment in power components, lowers equipment manufacturing costs, and facilitates unified control by operators, improving operational convenience.

[0029] In this embodiment, preferably, the welding mechanism 2 includes a base 201, a robot arm 202, and an arc welding gun 203. The base 201 is fixedly installed at the corner of the welding table 1, the robot arm 202 is fixedly installed on the base 201, and the arc welding gun 203 is fixedly installed on the robot arm 202. The arc welding gun 203 can be used to weld the plate, and the position of the arc welding gun 203 can be adjusted arbitrarily by the robot arm 202. Its beneficial effects are as follows: The base 201 provides a stable mounting support for the robotic arm 202 and the arc welding gun 203, ensuring that the welding mechanism 2 does not shake during the welding process and improving welding accuracy; The robotic arm 202 has a multi-degree-of-freedom adjustment function, which can drive the arc welding gun 203 to achieve flexible adjustment at any angle and position, and can accurately align with the joints of each plate, adapting to welding needs at different positions and angles, especially suitable for welding complex positions such as corners and edges of switch cabinet plate joints, avoiding welding blind spots; The stable installation of the arc welding gun 203 ensures arc stability during the welding process, reduces welding defects such as welding spatter and incomplete penetration, and improves welding quality; The four welding mechanisms 2 are respectively set at the four corners of the welding table 1, which can realize synchronous welding of the joints of four plates, further shortening the welding time and improving welding efficiency, while ensuring that the welding progress of each joint is consistent, avoiding plate deformation caused by sequential welding.

[0030] Please see Figures 1 to 8In this embodiment of the invention, a plurality of ball bearings 14 are embedded and installed on the upper surface of the support plate 1 3. The ball bearings 14 reduce the moving resistance when the plate is placed on the support plate 1 3. The adsorption and fixing assembly includes a suction cup seat 12 and a plurality of electric suction cups 13 fixedly installed on the suction cup seat 12. The top of the support plate 2 18 has a groove 1801, and the suction cup seat 12 is disposed in the groove 1801. At least two guide posts 3 15 are fixedly installed on the lower surface of the suction cup seat 12. The guide posts 3 15 penetrate the bottom wall of the support plate 2 18 and slide with the support plate 2 18. The bottom end of the guide posts 3 15 is fixedly fitted with a limiting ring 16, and the limiting ring 16 is connected to the support plate 2 18 by a spring 2 17. The bottom wall is elastically connected; a push plate 11 is fixedly installed on the top of the adjusting plate 9, and a through hole for the push plate 11 to pass through is opened in the middle of the support plate 3. The push plate 11 is located directly below the guide post 3 15. Its working principle is as follows: after the positioning mechanism 4 positions the plate, the adjusting plate 9 is driven to move upward by the hydraulic cylinder 10. The adjusting plate 9 drives the push plate 11 to move upward synchronously. When the push plate 11 moves upward, it contacts the bottom end of the guide post 3 15, and pushes the suction cup seat 12 to slide upward along the groove 1801 of the support plate 2 18 through the guide post 3 15, so that the electric suction cup 13 on the suction cup seat 12 is tightly attached to the bottom wall of the plate. Then the electric suction cup 13 is activated, and the plate is firmly adsorbed and fixed by the negative pressure adsorption principle. The core improvement of this embodiment lies in solving the technical pain point of the electric suction cup 13 affecting the positioning of the board in the prior art: During the research process, it was found that since the electric suction cup 13 has a certain adsorption force, if the electric suction cup 13 comes into contact with the board during the board positioning stage, it will generate a large friction force, which will hinder the movement and adjustment of the board, resulting in a decrease in positioning accuracy and a reduction in positioning efficiency.To solve this technical problem, this embodiment adopts a structural design for the adsorption and fixing components that can be raised and lowered for storage: Before positioning the board, the output end of the hydraulic cylinder 10 is in a partially retracted state, and the adjusting plate 9 drives the push plate 11 to a low position. The push plate 11 does not contact the bottom end of the guide post 15. At this time, under the elastic reset action of the spring 17, the suction cup seat 12 and the electric suction cup 13 are stored in the groove 1801 on the top of the support plate 18. When the board is placed on the support plate 18, it only contacts the ball bearings 14 on the support plate 3 and does not contact the electric suction cup 13, thereby completely eliminating the frictional effect of the electric suction cup 13 on the movement of the board. The hydraulic cylinder 10 extends to drive the adjusting plate 9 downwards, which in turn drives the transmission component 5 to move, thereby driving the positioning plate 405 to move and push the plate to the preset positioning position to complete the positioning. After positioning, the hydraulic cylinder 10 retracts to drive the adjusting plate 9 upwards, which first drives the transmission component 5 to reset, so that the positioning plate 405 is separated from the plate. Then, the adjusting plate 9 continues to move upwards, which drives the push plate 11 to push the suction cup seat 12 to rise, so that the electric suction cup 13 is attached to the bottom wall of the plate and the electric suction cup 13 is activated to achieve adsorption and fixation. The beneficial effects of this structure are as follows: it effectively resolves the contradiction between the electric suction cup 13 and the plate positioning, ensuring both the flexibility and accuracy of plate positioning and the stability of subsequent adsorption and fixation, preventing displacement of the plate during rotation and welding; the setting of the ball bearing 14 further reduces the moving resistance during plate positioning and improves positioning efficiency; the cooperation between the second spring 17 and the third guide post 15 realizes the automatic reset and storage of the suction cup seat 12, with ingenious structural design that requires no additional power drive and simplifies the operation process; the setting of multiple electric suction cups 13 can achieve multi-point uniform adsorption of the plate, improve the stability of adsorption and fixation, prevent the plate from deforming due to uneven force, and further ensure welding quality.

[0031] In this embodiment, preferably, a guide rail 28 is fixedly installed on the upper surface of the welding table 1, and a slide block 27 is slidably installed on the guide rail 28. A second locking knob 30 for locking the slide block 27 is provided on the slide block 27. The second locking knob 30, in conjunction with a bolt locking structure, locks the slide block 27. A support base 26 is fixedly installed on the slide block 27, and a hinge base 21 is fixedly installed on the side wall of the support base 26. A rotating base 20 is rotatably installed on the inner side of the hinge base 21. The rotating base 20 is fixedly connected to the support plate 18 via a connecting plate 19. The drive assembly includes a motor 25, a worm gear 24, a worm wheel 23, and a connecting shaft 22. The connecting shaft 22 passes through the hinge base 21 and the rotating base 20. The connecting shaft 22 is fixedly connected to the rotating base 20 and rotatably connected to the hinge base 21. The motor 25 and the support base 26... The side wall is fixedly connected, the output end of the motor 25 is fixedly connected to the worm 24, and the worm wheel 23 is fixedly connected to the end of the connecting shaft 22. The worm wheel 23 meshes with the worm 24. Its working principle is as follows: When the drive support plate 218 rotates, the motor 25 is started. The output end of the motor 25 drives the worm 24 to rotate at a constant speed. Since the worm wheel 23 meshes with the worm 24, the rotational power of the worm 24 is transmitted to the worm wheel 23, which drives the worm wheel 23 to rotate synchronously. The worm wheel 23 drives the connecting shaft 22, which is fixedly connected to it, to rotate. When the connecting shaft 22 rotates, it drives the rotating seat 20 to rotate along the inner side of the hinge seat 21. The rotating seat 20 drives the support plate 218 to rotate synchronously through the connecting plate 19, thereby smoothly rotating the plate to be welded from a horizontal position to a vertical welding position, ensuring that the position of the plate does not shift during the rotation process and that the connection with other plates is precisely aligned. The beneficial effects of this drive assembly and support structure are as follows: The worm gear 24 and worm wheel 23 transmission structure has the advantages of stable transmission ratio and good self-locking performance, ensuring that the support plate 18 can remain stable after rotating to a vertical position, preventing rotation due to external forces and ensuring the stability of the welding process; the motor 25, as the power source, provides stable and controllable power output, accurately controlling the rotation speed and angle of the support plate 18, ensuring that the four plates can rotate synchronously to the preset position, improving the docking accuracy; the sliding cooperation between the guide rail 28 and the slide 27 allows for overall position adjustment of the support plate 18 and drive assembly, further adapting to the welding requirements of switchgear plates of different sizes; the locking knob 30 allows for secure locking after the slide 27 position is adjusted, preventing the slide 27 from sliding during subsequent operation.

[0032] In this embodiment, preferably, the support plate 3 is fixedly connected to the slide 27 via the connecting plate 29, thereby supporting the support plate 18 and automatically adjusting the position of the positioning mechanism 4 when adjusting the position of the slide 27. The connecting plate 29 achieves a firm connection between the support plate 3 and the slide 27, providing stable support for the support plate 3 and the positioning mechanism 4 and support plate 18 above it, thus improving the overall structural stability of the device. When the position of the slide 27 is adjusted along the guide rail 28, the slide 27 drives the support plate 3 to move synchronously via the connecting plate 29, which in turn drives the positioning mechanism 4 to move synchronously, realizing the synchronous position adjustment of the positioning mechanism 4 and the support plate 18. There is no need to adjust the position of the positioning mechanism 4 separately, simplifying the operation process, ensuring that the relative position of the positioning mechanism 4 and the plate remains consistent, improving the convenience of operation and positioning accuracy, and further enhancing the overall linkage of the device to ensure coordinated operation of all components.
