[0003] A Chinese patent with authorization announcement number CN 115255741 B discloses a plate welding device, comprising: a housing with a horizontal through groove on its side wall and a power chamber on the top of one side of the housing; a feeding assembly including a sliding seat located below the power chamber, a mating block connected to the sliding seat inside the power chamber, second springs between the side walls of the mating block and the side wall of the power chamber, a bottom plate slidably mounted on the bottom of the mating block, a first rotating shaft passing through the mating block, a first gear shaft mounted on the first rotating shaft, a first rack mounted on the mating block, first threaded shafts rotatably mounted at both ends of the sliding seat with their top ends connected to second bevel gears, the second bevel gears meshing with the first bevel gears, the first bevel gears connecting to a connecting shaft, a first belt between the first rotating shaft and the connecting shaft, an inner sleeve sleeved around the first threaded shaft, an outer sleeve slidably mounted around the inner sleeve, and a suction cup connected to the bottom end of the inner sleeve. Therefore, this invention not only achieves automatic feeding but also clamps the plate in four directions.

[0004] Existing welding equipment typically requires vertical welding of two metal plates during the welding process of electrical distribution cabinets. However, due to the difficulty in fixing the positions of the two metal plates, the stability of the metal plates is poor, which affects the welding quality. Therefore, a plate welding device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a plate welding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a plate welding device, including a base, a control panel installed on the side wall of the base, a right-angle seat installed on the base, and clamping components respectively provided on the bottom plate and side plate of the right-angle seat. The clamping components include a sliding groove. The bottom plate of the right-angle seat has a sliding groove, and a double screw is rotatably connected to the inner wall of the sliding groove. The double screw includes a first screw and a second screw. A fixing block is fixedly connected between the first screw and the second screw. The thread directions on the first screw and the second screw are symmetrical and opposite. A damping wheel is installed at one end of the first screw. Two sliders are symmetrically assembled in the sliding groove. A clamp is installed on the slider. The clamp has an L-shaped structure. A threaded hole is opened on the top plate of the clamp. A small screw is assembled in the threaded hole. A knob is installed on the small screw. A pressure plate is rotatably connected to the bottom of the rod, and the pressure plate is slidably connected to the clamping seat. A first metal plate and a second metal plate are respectively placed on the right-angle seat. The first metal plate and the second metal plate are in contact with the bottom plate and the side plate of the right-angle seat, respectively. By placing the first metal plate on the bottom plate of the right-angle seat, the two clamping seats clamp and fix the first metal plate. Then, a small screw drives the pressure plate to move vertically downward, and the pressure plate presses down on the first metal plate, thereby limiting the position of the first metal plate in the vertical direction. Similarly, the clamping components on the side plate of the right-angle seat clamp and fix the second metal plate, thereby limiting the position of the second metal plate. This structure, by clamping the first metal plate and the second metal plate on the right-angle seat, keeps the welding joint of the first metal plate and the angle accurate, which is beneficial to improving the stability of the metal plates and the welding quality.

[0007] Preferably, a support frame is mounted on the base, a guide plate is mounted on the support frame, a guide groove is formed in the guide plate, a stepper motor is mounted on the side wall of the support frame via a base, a lead screw is mounted on the output shaft of the stepper motor, the lead screw is rotatably mounted on the inner wall of the guide groove, a guide block is assembled in the guide groove, a moving frame is mounted on the guide block, a hydraulic cylinder is mounted on the moving frame, a hydraulic rod is mounted on the hydraulic cylinder, and a welding torch is mounted on the bottom end of the hydraulic rod via a connecting frame. By clamping the first metal plate and the second metal plate on the right-angle base, the weld seam between the first metal plate and the second metal plate is located at the right angle of the right-angle base, and the welding torch on the moving frame is opposite to the right angle of the right-angle base, the welding torch is quickly aligned with the weld seam. Then, the hydraulic rod drives the welding torch to move diagonally downward, while the moving frame drives the welding torch on it to move horizontally from left to right, realizing the rapid and efficient welding of the weld seam by the welding torch, which is beneficial to improving the efficiency of welding.

[0008] The advantages of this utility model are:

[0009] 1. This utility model places a first metal plate on the base plate of a right-angle seat, with two clamps holding and fixing the first metal plate. Then, a small screw drives a pressure plate to move vertically downward, pressing the first metal plate and thus limiting its vertical position. Similarly, the clamping components on the side plate of the right-angle seat clamp and fix the second metal plate, thus limiting its position. This structure, by clamping the first and second metal plates on the right-angle seat, ensures that the weld joint between the first and second metal plates remains stable and the angle is accurate, which is beneficial to improving the stability of the metal plates and the welding quality.

[0010] 2. This utility model clamps a first metal plate and a second metal plate onto a right-angle base. The weld seam between the first metal plate and the second metal plate is located at the right angle of the right-angle base, and the welding torch on the moving frame is opposite to the right angle of the right-angle base. This enables the welding torch to be quickly aligned with the weld seam. Then, the hydraulic rod drives the welding torch to move diagonally downward, while the moving frame drives the welding torch on it to move horizontally from left to right. This enables the welding torch to weld the weld seam quickly and efficiently, which is beneficial to improving the efficiency of welding. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3As shown, a plate welding device includes a base 1, a control panel 2 mounted on the side wall of the base 1, a right-angle seat 3 mounted on the base 1, and clamping components respectively provided on the bottom plate and side plate of the right-angle seat 3. The clamping components include a slide groove 4. The slide groove 4 is formed on the bottom plate of the right-angle seat 3, and a double screw is rotatably connected to the inner wall of the slide groove 4. The double screw includes a first screw 5 and a second screw 6. A fixing block 7 is fixedly connected between the first screw 5 and the second screw 6. The thread directions on the first screw 5 and the second screw 6 are symmetrical. Conversely, a damping wheel 8 is installed at one end of the first screw 5, and two sliders 9 are symmetrically assembled in the slide groove 4. A clamp 10 is installed on the slider 9. The clamp 10 has an L-shaped structure, and a threaded hole is opened on the top plate of the clamp 10. A small screw 11 is installed in the threaded hole, and a knob 12 is installed on the small screw 11. A pressure plate 13 is rotatably connected to the bottom side of the small screw 11. The pressure plate 13 is slidably connected to the clamp 10. A first metal plate 14 and a second metal plate 15 are respectively placed on the right-angle seat 3. 15 is respectively attached to the base plate and side plate of the right-angle seat 3; during operation, the existing welding device usually needs to weld two metal plates vertically during the welding process of the distribution cabinet. Due to the difficulty in fixing the position of the two metal plates, the stability of the metal plates is poor, which affects the welding quality. By placing the first metal plate 14 on the base plate of the right-angle seat 3, and then rotating the damping wheel 8 on the base plate of the right-angle seat 3, the damping wheel 8 drives the first screw 5 and the second screw 6 to rotate. The first screw 5 and the second screw 6 drive the two sliders 9 on them to move synchronously relative to each other. The two sliders 9 drive the two clamps 10 to move synchronously relative to each other. The two clamps 10 clamp and fix the first metal plate 14, realizing the horizontal limitation of the first metal plate 14; then, rotate the knob 12 on the two clamps 10 respectively, driving the small screw 11 to rotate. The small screw 11 drives the pressure plate 13 to move vertically downward. The pressure plate 13 presses the first metal plate 14, realizing the vertical limitation of the first metal plate 14;

[0020] The second metal plate 15 is then spliced ​​onto the first metal plate 14, with the first metal plate 14 abutting against the side plate of the right-angle base 3. Similarly, the clamping components on the side plate of the right-angle base 3 clamp and fix the second metal plate 15, thus limiting the position of the second metal plate 15. In this structure, the first screw 5, the second screw 6, and the small screw 11 have self-locking properties. This structure clamps the first metal plate 14 and the second metal plate 15 onto the right-angle base 3, ensuring that the weld joint of the first metal plate 14 and the second metal plate 15 remains stable and the angle is accurate, which is beneficial to improving the stability of the metal plates and the welding quality.

[0021] Please see Figure 4-5As shown, a support frame 16 is mounted on the base 1, and a guide plate 17 is mounted on the support frame 16. A guide groove 18 is formed in the guide plate 17. A stepper motor 19 is mounted on the side wall of the support frame 16 via a base. A lead screw 20 is mounted on the output shaft of the stepper motor 19. The lead screw 20 is rotatably mounted on the inner wall of the guide groove 18. A guide block 21 is assembled in the guide groove 18. A moving frame 22 is mounted on the guide block 21. A hydraulic cylinder 23 is mounted on the moving frame 22. A hydraulic rod 24 is mounted on the hydraulic cylinder 23. A welding torch 25 is mounted on the bottom end of the hydraulic rod 24 via a connecting frame. During operation, the existing welding device has difficulty efficiently welding the plates during the welding process of the power distribution cabinet, and it is difficult to quickly align the welding torch 25 with the weld seam, resulting in low welding efficiency. The method is inferior. By clamping the first metal plate 14 and the second metal plate 15 onto the right-angle base 3, the weld seam between the first metal plate 14 and the second metal plate 15 is located at the right angle of the right-angle base 3, and the welding torch 25 on the moving frame 22 is opposite to the right angle of the right-angle base 3, thus achieving rapid alignment of the welding torch 25 with the weld seam. Then, by operating the hydraulic cylinder 23, the hydraulic rod 24 drives the welding torch 25 to move diagonally downward. At the same time, by operating the stepper motor 19, the lead screw 20 is driven to rotate. The lead screw 20 drives the guide block 21 on it to move horizontally from left to right. The guide block 21 drives the moving frame 22 to move horizontally from left to right. The moving frame 22 drives the welding torch 25 on it to move horizontally from left to right. This achieves rapid and efficient welding of the weld seam by the welding torch 25, which is beneficial to improving the efficiency of welding.

[0022] Working principle: Existing welding devices typically require vertical welding of two metal plates during the welding process of power distribution cabinets. However, the difficulty in fixing the positions of the two metal plates leads to poor stability and affects welding quality. By placing the first metal plate 14 on the base plate of the right-angle seat 3, and then rotating the damping wheel 8 on the base plate of the right-angle seat 3, the damping wheel 8 drives the first screw 5 and the second screw 6 to rotate. The first screw 5 and the second screw 6 drive the two sliders 9 on them to move synchronously relative to each other. The two sliders 9 drive the two clamps 10 to move synchronously relative to each other. The two clamps 10 then clamp the first metal plate 14... The clamping and fixing mechanism effectively limits the horizontal movement of the first metal plate 14. Then, rotating the knobs 12 on the two clamping seats 10 rotates the small screw 11, causing the pressure plate 13 to move vertically downwards. The pressure plate 13 presses down on the first metal plate 14, thus limiting its vertical position. Next, the second metal plate 15 is attached to the first metal plate 14, with the first metal plate 14 in contact with the side plate of the right-angle seat 3. Similarly, the clamping components on the side plate of the right-angle seat 3 clamp and fix the second metal plate 15, thus limiting its position. In this structure, the first... Screw 5, second screw 6, and small screw 11 are self-locking. This structure, by clamping the first metal plate 14 and the second metal plate 15 onto the right-angle base 3, ensures that the weld joint of the first metal plate 14 and the second metal plate 15 remains stable and the angle is accurate, which is beneficial to improving the stability of the metal plates and the welding quality. Existing welding devices have difficulty in efficiently welding plates during the welding process of distribution cabinets, and it is difficult to quickly align the welding torch 25 with the weld seam, resulting in poor welding efficiency. By clamping the first metal plate 14 and the second metal plate 15 onto the right-angle base 3, the first metal plate 14 and the second metal plate 15 are self-locking. The weld seam between 15 is located at the right angle of the right angle seat 3, and the welding torch 25 on the moving frame 22 is opposite to the right angle of the right angle seat 3, which realizes the quick alignment of the welding torch 25 with the weld seam. Then, the hydraulic cylinder 23 operates, and the hydraulic rod 24 drives the welding torch 25 to move diagonally downward. At the same time, the stepper motor 19 operates, which drives the lead screw 20 to rotate. The lead screw 20 drives the guide block 21 on it to move horizontally from left to right. The guide block 21 drives the moving frame 22 to move horizontally from left to right. The moving frame 22 drives the welding torch 25 on it to move horizontally from left to right. This realizes the rapid and efficient welding of the weld seam by the welding torch 25, which is conducive to improving the efficiency of welding.
