Description

Technical Field

[0001] The utility model relates to the technical field of air cooler tube bundle welding devices, in particular to an air cooler tube bundle welding device. Background Technique

[0002] An air cooler is a device that uses ambient air as a cooling medium, flowing across the outside of finned tubes to cool or condense the high-temperature process fluid inside the tubes. It is abbreviated as "air cooler" and also known as "air-cooled heat exchanger". Generally, it is mainly composed of tube bundles, tube boxes, fans, louvers, and frameworks. There are still some defects in the existing devices; for example;

[0003] For example, an air cooler tube bundle welding device with the publication number CN219444067U. When in use, it includes a platform. Two groups of first support plates are fixedly connected to the top of the platform. Two groups of first support plates are rotatably connected to a double-headed screw through bearings. Two groups of plate bodies are threadedly connected to the double-headed screw. Two groups of plate bodies are rotatably connected to round rods through bearings. The utility model uses the double-headed screw to drive two groups of plate bodies to move relatively, so as to adjust the distance between two groups of first rollers, and then different-diameter tube bundles can be placed between the two groups of first rollers. After placement, the push rod is driven to make two groups of second rollers contact the tube bundle, and the motor is driven to drive one group of first rollers to rotate, so that the tube bundle can rotate 360 degrees between the two groups of second rollers and the first rollers. Then, the two fitted tube bundles can be comprehensively welded by a welding gun head. There are some problems with the above device. Although the welding device can be well applied to weld the tube bundle during use, it usually can only weld one position of the tube bundle. During the welding process, the whole circle of the tube bundle needs to be welded, which is not convenient for welding other positions, making it difficult for the welding efficiency of the welding device for the tube bundle to reach the established expectation. Therefore, we propose an air cooler tube bundle welding device to solve the above-mentioned problems. Content of the Utility Model

The inside of the rotating plate 7 is fixedly connected to a connecting block 8, and a fixing mechanism is arranged in the connecting block 8. The fixing mechanism includes the connecting block 8, a first push rod 9, a support rod 10, and a fixing arm 11. The inside of the connecting block 8 is fixedly connected to the first push rod 9, and the front end of the first push rod 9 is hinged to the support rod 10, and the front end of the support rod 10 is hinged to the fixing arm 11. The fixing arms 11 are arranged symmetrically about the center of the connecting block 8, and the tails of the fixing arms 11 are hinged to the connecting block 8, and anti-slip pads are arranged on the surfaces of the fixing arms 11. The inside of the fixing plate 12 is slidably connected to a rotating block 13, and the rotating block 13 is fixedly connected to the connecting block 8, and the fixing plate 12 is slidably connected to the machine body 1. The connecting block 8 is arranged symmetrically about the centers of the fixing plate 12 and the rotating plate 7, and fixing mechanisms are arranged in all the connecting blocks 8;

[0020] After one end of the tube is inserted into the inside of the rotating plate 7, at this time, start the first push rod 9 in the connecting block 8 inside the rotating plate 7 to drive the support rod 10 to adjust. At the same time, the support rod 10 drives the fixing arm 11 to adjust through a hinge shaft, so that after the fixing arm 11 contacts the surface of the tube, at this time, drive the lead screw 3 to rotate through the first motor 2, so that the lead screw 3 drives the first slider 4 and the second slider 21 to move simultaneously, so that the rotating plates 7 and the fixing plates 12 on both sides approach each other. After one end of the tube is inserted into the fixing plate 12, the tube is fixed by the fixing arms 11 on the surface of the connecting block 8 inside the fixing plate 12;

[0021] The machine body 1 is connected to a moving block 14 through a moving mechanism.

After moving the welding head 20 to the position where the pipe needs to be welded, the second push rod 19 drives the welding head 20 to descend to weld the surface of the pipe. At the same time, during the welding process, the second motor 6 can drive the rotating plate 7 to rotate, causing the rotating plate 7 to drive the pipe to rotate. At the same time, the pipe drives the connecting block 8 inside the fixing plate 12 to rotate inside the fixing plate 12 through the rotating block 13, facilitating welding of different positions of the pipe, thereby completing a series of operations.
