[0019] In order to more clearly understand the above objects, features and advantages of the utility model, the following further detailed description of the utility model is made in conjunction with the drawings and specific embodiments.

[0020] Such as Figure 1 - Figure 4An automatic welding device for boiler pipes as shown includes a base 1. At the top of the base 1, there are two sliding rails 2. A moving table 4 is slidably connected to the surfaces of the two sliding rails 2. Inside the moving table 4, there is a cooling mechanism. The cooling mechanism includes a water pump 12 fixedly installed at the top of the moving table 4. Inside the moving table 4, there is a water tank 13. The input end at the bottom of the water pump 12 is arranged inside the water tank 13. On one side of the water tank 13, there is a water injection port 14. The output end at the bottom of the water pump 12 is fixedly installed with a spray head 15. On the surface of the base 1, there is a water guide groove 16. During the welding process, through the cooling mechanism, the water stored in the water tank 13 can be sprayed out from the spray head 15 and sprayed on the inner wall of the boiler pipe, thereby cooling the boiler pipe. After the boiler pipe is welded, its own temperature will not scald the staff, and thus the welded boiler pipe can be immediately taken out. While protecting the staff from being scalded by high temperature, it can also improve the welding efficiency of the boiler pipe.

[0021] At the top of the base 1, there is a fixed table 3 fixedly installed. Inside the fixed table 3, there is a clamping mechanism. The clamping mechanism includes a driving motor 5 fixedly installed on one side of the fixed table 3. The output end of the driving motor 5 is fixedly installed with a chuck 6. Inside the chuck 6, there are multiple jaws 7. The chuck 6 is located on the side of the fixed table 3 opposite to the driving motor 5. Through the multiple jaws 7, the boiler pipe can be fixed. At the same time, by using the characteristics of the chuck 6 itself, boiler pipes of different sizes can be fixed, improving the wide applicability of this device.

[0022] Inside the moving table 4, there is an auxiliary mechanism. The auxiliary mechanism includes a rotating seat 8 rotatably connected to one side of the moving table 4. On the side of the rotating seat 8 close to the fixed table 3, there is a tapered disk 9 fixedly connected. When fixing a circular pipe, the tapered disk 9 can receive the boiler pipe towards the middle, and at the same time cooperate with the clamping mechanism to align the centers of the two sections of the boiler pipe, facilitating its welding and ensuring the quality of the welded boiler pipe.

[0023] The fixed table 3 and the moving table 4 are cooperated through the two sliding rails 2. The centers of the rotating seat 8 and the chuck 6 are located on the same horizontal plane. The sliding rails 2 can drive the moving table 4 to slide on the surface of the base 1, so that the fixed table 3 and the moving table 4 are cooperated, and thus by the cooperation of the clamping mechanism and the auxiliary mechanism, the two sections of boiler pipes to be welded are fitted together, facilitating the welding of the boiler pipe.

[0024] On one side of the base 1, there is a welding bracket 10 fixedly connected. At the top of the welding bracket 10, there is a welding head 11 fixedly installed. The welding bracket 10 can rotate at multiple angles, so that the position to be welded can be more accurately controlled, and the two sections of boiler pipes are welded by using the welding head 11. The welding bracket 10 is controlled by a program to complete the semi-automatic welding work.

[0025] The spray head 15 is in a penetrating state with the rotating seat 8 and is arranged inside the conical disc 9. The water guide groove 16 is arranged between the two slide rails 2. The water guide groove 16 can re-collect the water sprayed by the spray head 15 on the inner wall of the pipeline, and after being treated and recycled, it is recovered and reused to save water resources.

[0026] Working principle: First, the boiler pipeline to be welded needs to be installed on the chuck 6. Subsequently, another section of the boiler pipeline is placed on the surface of the conical disc 9. Then, the moving table 4 is moved and approached to the fixed table 3 by using the slide rails 2, so that the two sections of the boiler pipeline are in contact. As the moving table 4 moves, the two sections of the boiler pipeline are squeezed and fixed. Subsequently, the welding bracket 10 can be controlled by a program. After finding the welding position, the welding head 11 will weld the boiler pipeline. During the welding process, the water pump 12 will pump out the water in the water tank 13 and spray it out from the spray head 15, spraying it on the inner wall of the boiler pipeline, thereby cooling the welded boiler pipeline. And except for the evaporated water flow, the remaining water flow will flow out from one end of the chuck 6, and the water flow is recycled and reused through the water guide groove 16. After the welding is completed, the boiler pipeline can be immediately removed, facilitating the next welding, thus preventing the staff from being scalded and at the same time improving the welding efficiency of the boiler pipeline.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
