A distribution box is a low-voltage power distribution device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Due to its simple structure and high practicality, it is widely produced and used. During the manufacturing of a distribution cabinet, the various metal casings need to be welded together, and finally, the welded distribution cabinet is welded to the chassis. In most cases, manual support is used when welding the distribution cabinet to the chassis. However, placing the distribution cabinet on the chassis for support in this way causes it to wobble, leading to misalignment and insufficient welding precision. Utility Model Content

[0019] Reference Figures 1 to 4 This utility model provides a chassis welding device for processing power distribution cabinets: It includes a welding station 1, a controller 2 fixedly connected to the front side of the welding station 1, a turntable 8 rotatably connected to the center of the top surface of the welding station 1, a first rotary motor 20 embedded in the top surface of the welding station 1, a first rotating shaft 19 whose output end is connected to the first rotating shaft 19, the first rotating shaft 19 being vertically fixed to the bottom surface of the turntable 8, a pad 10 fixedly connected to the center of the top surface of the turntable 8, a first clamping member on the top surface of the turntable 8, a frame 3 fixedly connected to the top surface of the welding station 1, a top plate 5 lifted and lowered inside the frame 3, and two mirror-symmetrical first lifting motors vertically fixed to the top surface of the frame 3. 4. Each first lifting motor 4 has a first guide rod connected to its output end. The first guide rod slides axially through the top surface of the frame 3 and is vertically fixed to the top surface of the top plate 5. The bottom surface of the top plate 5 is connected to a circular plate 6. The bottom surface of the top plate 5 is vertically fixed to two mirror-symmetrical second lifting motors 13. Each second lifting motor 13 has a second guide rod 12 connected to its output end. Both second guide rods 12 are vertically fixed to the top surface of the circular plate 6. The bottom surface of the circular plate 6 is provided with a second clamping member. The center of the top surface of the circular plate 6 has an axial through hole 21. A negative pressure member is movably connected inside the through hole 21. The negative pressure member is rotatably connected to the top plate 5.

[0020] Reference Figures 1 to 3 In order to fix the cabinet body when welding the electrical cabinet to the base plate, the first clamping component includes four first electric push rods 9 horizontally fixed on the top surface of the turntable 8. The four first electric push rods 9 are distributed in a ring at equal distances on the top surface of the turntable 8. Each first electric push rod 9 has a first clamping plate 7 fixed at its end. The first clamping plate 7 is radially slidably connected to the top surface of the turntable 8.

[0021] Reference Figures 1 to 3 In order to achieve the purpose of aligning and positioning the base plate with the electrical cabinet, the second clamping component includes four second electric push rods 11 that are horizontally fixed to the bottom surface of the circular plate 6. The four second electric push rods 11 are distributed in a ring at equal intervals on the bottom surface of the circular plate 6. Each second electric push rod 11 has a second clamping plate 18 fixed to its end. The second clamping plate 18 is radially slidably connected to the bottom surface of the circular plate 6.

[0022] Reference Figures 1 to 4 In order to fix the base plate when welding it to the cabinet, the negative pressure component includes a second rotary motor 14 that is vertically fixed to the center of the bottom surface of the top plate 5. The output end of the second rotary motor 14 is connected to a second rotating shaft 15. The end of the second rotating shaft 15 is fixedly connected to a hollow block 17. The hollow block 17 is circular and its diameter is smaller than the diameter of the through hole 21. The top surface of the hollow block 17 is vertically connected to two radially symmetrical air pumps 16, and the bottom surface of the hollow block 17 is vertically connected to multiple air holes 22 that communicate with its interior.

[0023] By setting up the first clamping component, the second clamping component, and the negative pressure component, the cabinet body and the base plate of the electrical cabinet are automatically clamped and fixed during welding. This avoids the displacement of the base plate and the cabinet body when welding by manually clamping the cabinet body and the base plate, which would affect the welding effect of the cabinet body and the base plate. This ensures the stability of the cabinet body and the base plate during welding and improves the welding effect of the cabinet body and the base plate.

[0024] Working principle: In use, first, place the bottom plate face up on the pad 10. Then, the first lifting motor 4 drives the top plate 5 to descend, and the top plate 5 drives the circular plate 6 to descend, so that the bottom plate and the bottom surface of the circular plate 6 are in contact. Next, the four second electric push rods 11 simultaneously push the second clamping plates 18 towards the bottom plate, so that the four sides of the bottom plate are clamped and fixed by the four second clamping plates 18 respectively. At this time, the center of the bottom plate will be on the same vertical line as the center of the welding station 1. Then, the first lifting motor drives the top plate 5 to rise. Raise the base plate to its highest point, then place the cabinet bottom-up on the top surface of the turntable 8. Simultaneously, four first electric push rods 9 push four first clamping plates 7 to clamp and secure the cabinet. Then, the first lifting motor 4 lowers the top plate 5, which in turn lowers the circular plate 6 along with the base plate, ensuring the base plate is flush with and aligned with the required welding points on the cabinet. Then, two air pumps 16 simultaneously draw air upwards, removing the air between the hollow block 17 and the base plate through the air holes 22. This allows the base plate to be fixed to the bottom surface of the hollow block 17 by negative pressure adsorption. Then, the second electric... Push rod 11 causes the four second clamping plates 18 to separate from the base plate. Then, the second lifting motor 13 drives the circular plate 6 to rise, causing the circular plate 6 to separate from the base plate. The hollow block 17 then replaces the second clamping plates 18 to fix the base plate. Welding can then proceed between the base plate and the cabinet. Once one side of the cabinet and base plate is welded, the first rotary motor 20 and the second rotary motor 14 begin to run synchronously in the same direction and at the same speed, causing the turntable 8 and the hollow block 17 to rotate synchronously at the same speed and in the same direction, rotating the cabinet and base plate to the other side. Welding then continues. After welding is completed, rotate to the third side again until all four sides are welded. When the base plate and cabinet are welded, the air pump 16 is turned off, the air pressure between the base plate and the hollow block 17 is restored, the first lifting motor 4 will drive the top plate 5 to rise, so that the hollow block 17 is separated from the base plate. At the same time, the second lifting motor 13 will drive the circular plate 6 to fall, so that the bottom surface of the circular plate 6 is flush with the bottom surface of the hollow block 17. Then the first electric push rod 9 will separate the first clamping plate 7 from the welded cabinet. Then the cabinet welded to the base plate can be removed from the turntable 8.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
