A turntable 4 is provided on the upper side of the water tray 2, which is concentric with it. Welding stations 5 are distributed in a circle on the turntable 4. The turntable 4 is driven to rotate by a servo motor 8 to realize multi-station cyclic operation and improve production efficiency. A drain pipe is provided at the bottom of the water tray 2. The drain pipe is connected to the water tank 6 in the equipment box 1 to drain the water in the water tray 2 and keep the water tray 2 clean.

[0017] Working principle: The servo motor 8 drives the turntable 4 to rotate, which delivers different welding stations 5 to the operator in turn. The operator can perform manual brazing operations at each station. The material tray 3 facilitates the centralized storage and retrieval of workpieces, improving the convenience of operation.

[0018] The equipment box 1 contains a water tank 6, a water pump 7, a servo motor 8, and an electrical control cabinet 12. The servo motor 8 is fixed to the lower side of the water pan 2, providing power for the rotation of the turntable 4. The water pump 7 draws water from the water tank 6 and divides it into two streams through a three-way connector 23. One stream is sent into a three-way connector 24, and the other stream is connected to the wastewater outlet 61 and returns to the water tank 6, realizing the recycling of water. The servo motor 8 drives the spur gear 17 to rotate through the planetary reducer 9. A rotary bearing 18 meshes with the spur gear 17 on one side. The inner ring 181 of the rotary bearing 18 is fixedly set, and the inner ring 181 rotates with the outer ring 182. The outer ring 182 rotates with the spur gear 17. The outer ring 182 of the rotary bearing 18 is connected and fixed to the turntable 4 to ensure that the turntable 4 can rotate smoothly and accurately.

[0019] The water flow continues through the three-way connector 24 and is then divided into two streams. One stream is delivered to the water-air slip ring 10 for cooling and protecting the welding area, and the other stream is delivered to the water-cooled nozzle 15. The water-cooled nozzle 15 is fixed above one side of the water tray 2 and sprays water toward the welding station 5. The water-cooled nozzle 15 is supplied with water by the water pump 7 to achieve cooling of the welding area.

[0020] Water tank 6 provides water for the cooling system and is fixed at the bottom of equipment box 1. Water pump 7 controls the flow of water.

Electrical control cabinet 12 provides intelligent control of the entire equipment and coordinates the work of each component.

[0021] The protection system includes a water-air slip ring 10 and a water-air distribution plate 13. The water-air slip ring 10 is installed below the water pan 2 via a fixing bracket 11. The water-air slip ring 10 has multiple water inlets 103 and air inlets 101, as well as water outlets 104 and air outlets 102. The water inlets 103 are connected to the water pump 7, and the air inlets 101 are connected to an external nitrogen delivery mechanism. The water-air distribution plate 13 is located above the water-air slip ring 10, and the two are connected and fixed by a support rod 16. The water-air distribution plate 13 is also connected and fixed to the turntable 4. The water-air distribution plate 13 is connected to the water outlets 104 and 102 on the water-air slip ring 10 via water inlet pipes 131 and 132, respectively.

Water supply pipe 26 and air supply pipe 27 respectively supply cooling water and nitrogen to the welding fixture on welding station 5. Water-air slip ring 10 is divided into two parts that can rotate and communicate with each other. Water interface 103 and air interface 101 are located in the lower half of water-air slip ring 10, and water outlet 104 and air outlet 102 are located in the upper half of water-air slip ring 10. The lower end of support rod 16 is connected and fixed to the upper half of water-air slip ring 10.

[0022] Water pump 7 delivers water into water-air slip ring 10, which distributes it to each welding station 5 via water-air distribution plate 13 to cool the welding fixture and prevent it from overheating during the welding process. An external nitrogen delivery mechanism delivers nitrogen to the welding station 5 via water-air slip ring 10 and water-air distribution plate 13 to provide gas protection for the welding area, prevent workpiece oxidation, and improve welding quality.

[0023] Nitrogen delivery mechanism: The nitrogen delivery mechanism includes an external gas source 25 and a pressure regulating filter 19 and a gas flow meter 20 installed on the equipment box 1. The nitrogen in the gas source is connected to the gas passage interface 101 of the water-gas slip ring 10 after passing through the pressure regulating filter 19 and the gas flow meter 20. It can accurately control the pressure and flow of nitrogen to meet the needs of different welding processes.

[0024] Water tray 2 structure: Water tray 2 is a ring structure with a through hole in the center. The spur gear 17 and the rotary bearing 18 are located inside the through hole. The support rod 16 passes through the center of the rotary bearing 18. This design makes the structure more compact, saves space, and ensures the reasonable layout and coordinated operation of the components.

[0025] Drain pipe filter 21: A filter 21 is installed on the drain pipe to filter impurities in the water, prevent clogging of the water tank 6 and water pump 7, and extend the service life of the equipment.

[0026] Pipe clamp setup: The turntable 4 is equipped with multiple vertical rods 14, each corresponding to a welding station 5. The vertical rods 14 are located inside the welding station 5 and are equipped with vertically movable pipe clamps. Water pipes 26 and air pipes 27 can be clamped into these clamps, facilitating the organization and securing of the water pipes 26 and air pipes 27, preventing pipe tangling from affecting operation. Figure 11 As shown, it consists of a retaining ring 141 and a circular pipe clamp 142. The retaining ring 141 is fitted onto the vertical rod 14, and the gas pipe 27 and water pipe 26 are clamped in the pipe clamp 142. The pipe clamp 142 is rotatably connected to the retaining ring 141. An opening is provided on the outside of the pipe clamp 142 so that the gas pipe 27 and water pipe 26 can be clamped into the pipe clamp 142 from the opening.

[0027] Control system: The control system of this device is installed in the electrical control cabinet 12. The control panel 22 is set on one side of the equipment box 1. The control panel 22 is electrically connected to the control system, which facilitates the operation and monitoring of the equipment by the operator and realizes intelligent control.

[0028] Switch valves can also be installed on the gas pipeline 27 and the water pipeline 26 to control the opening and closing of the pipeline individually.

[0029] like Figure 10 As shown, the welding fixture is installed on the welding station 5 of the turntable 4, including a fixed plate 28 and a support mechanism 29. The fixed plate 28 is provided with mounting holes 281, which are fixed to the positioning holes 51 on the welding station 5 by bolts. The welding workpiece 32 is supported by the support mechanism 29. A water cooling mechanism is provided in the support mechanism 29. The parts of the welding workpiece 32 that require water cooling are installed on the water cooling mechanism. The water cooling mechanism is provided with an inlet 30 and an outlet 31. The inlet 30 is connected to the water supply pipe 26, and the water flows out of the outlet 31 into the water pan 2 and finally flows back to the water tank 6. The part of the welding workpiece 32 that requires nitrogen protection is directly connected to this part through the gas supply pipe 27.

[0030] like Figure 11 As shown, the tooling is equipped with a nitrogen connection port 33. Nitrogen gas is introduced into the workpiece 32 through the nitrogen gas connection port 33 and the gas supply pipe 27 to protect the workpiece 32 during welding. In this tooling, water cooling is achieved by spraying water directly onto the welded workpiece through the water cooling nozzle 15. This water cooling does not need to be connected to the water supply pipe 26 and can be achieved through external water cooling.

[0031] It should be noted that although the connection diagrams of the relevant connecting pipes are not directly shown in the attached drawings, they can be inferred from the description and the accompanying drawings. Figure 1 The flowchart clearly shows the pipeline connection method of this utility model.
