[0001] This utility model relates to the field of welding gun head technology, specifically a tube sheet welding gun head. Background Technology

[0002] Tube sheets are mainly used in chemical containers, such as shell and tube heat exchangers, pressure vessels, boilers, condensers, central air conditioning, evaporators, and seawater desalination, to support and fix the tubes. The metal material gives it not only high rigidity but also great thermal conductivity.

[0003] In the existing technology, when welding tube sheets and tubes, manual welding and hand-held welding devices are mainly used to weld in a circumferential path. However, dozens of tubes may be installed on the surface of a tube sheet, which makes welding labor-intensive and troublesome. Therefore, an improved tube sheet welding gun head is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a tube sheet welding gun head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tube sheet welding gun head, comprising a tube sheet, wherein a series of tubes are arranged in the middle of the tube sheet, and a welding mechanism is arranged between the tube sheet and the series of tubes. The welding mechanism includes a fixed plate, a sliding groove, a sliding block, a tensioning plate, a rotating ring, and a welding head. A fixed plate is arranged on one side of the series of tubes. A plurality of sliding grooves are evenly opened on the outer surface of the fixed plate. A sliding block is movably engaged inside the sliding groove. A tensioning plate is fixedly arranged on the outer surface of the sliding block. A rotating ring is movably arranged on the outer side of the fixed plate through a bearing. A welding head is fixedly arranged on the surface of the rotating ring.

[0006] Preferably, a transmission mechanism for controlling the tension of the tensioning plates is provided between the tensioning plates. The transmission mechanism includes a movable sleeve, a screw, a threaded sleeve, a first pressing block, and a second pressing block. The movable sleeve is provided between the tensioning plates. A screw is fixedly provided in the middle of the inner side of the movable sleeve. A threaded sleeve is screwed onto the outer surface of the screw. A plurality of first pressing blocks are uniformly fixed on the outer surface of the movable sleeve. A second pressing block is fixed on the outer surface of the tensioning plate. The transmission mechanism can control the tensioning plates to perform tensioning work as needed, so that the welding head is fixed at one end of the tube. This can greatly reduce the labor intensity of the workers. The workers only need to control the welding progress, thus improving the comfort of the workers when facing the welding work.

[0007] Preferably, a handle is fixedly provided on one side of the rotating ring surface. By rotating the rotating ring with the handle, the welding head can be easily driven to move in a ring. In this way, the welding head can be used to perform ring welding work at the connection between the tube and the tube sheet.

[0008] Preferably, the inclined surfaces of the first extrusion block and the second extrusion block are in contact with each other, such as... Figure 3 As shown, when the movable sleeve moves toward the fixed plate, the first pressing block presses the second pressing block, causing the tension plate to open outwards. In this way, the tension plate can be tensioned and fixed inside the tube, thus fixing the entire device.

[0009] Preferably, a screwing block is fixedly provided at one end of the threaded sleeve, which allows the operator to easily rotate the threaded sleeve.

[0010] Preferably, a rubber pad is provided on the outer surface of the tensioning plate. The rubber pad can increase the friction on the outer surface of the tensioning plate, thereby improving the stability of the tensioning plate inside the tube.

[0015] 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 protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a welding gun head for a tube sheet 1, including a tube sheet 1, with a tube column 2 arranged in the middle of the tube sheet 1, and a welding mechanism arranged between the tube sheet and the tube column 2. The welding mechanism includes a fixed plate 3, a sliding groove 4, a slider 5, a tensioning plate 6, a rotating ring 7, and a welding head 8. A fixed plate 3 is arranged on one side of the tube column 2. A plurality of sliding grooves 4 are evenly opened on the outer surface of the fixed plate 3. A slider 5 is movably engaged inside the sliding groove 4. A tensioning plate 6 is fixedly arranged on the outer surface of the slider 5. A rotating ring 7 is movably arranged on the outer side of the fixed plate 3 through a bearing. A welding head 8 is fixedly arranged on the surface of the rotating ring 7.

[0017] A transmission mechanism for controlling the tension of the tension plates 6 is provided between the tension plates 6. The transmission mechanism includes a movable sleeve 9, a screw 10, a threaded sleeve 11, a first pressing block 12, and a second pressing block 13. The movable sleeve 9 is provided between the tension plates 6. The screw 10 is fixedly provided in the middle of the inner side of the movable sleeve 9. The threaded sleeve 11 is screwed onto the outer surface of the screw 10. Several first pressing blocks 12 are uniformly fixed on the outer surface of the movable sleeve 9. The second pressing blocks 13 are fixed on the outer surface of the tension plates. The transmission mechanism can control the tension of the tension plates 6 to perform tensioning work as needed, so that the welding head 8 is fixed at one end of the tube 2. This can greatly reduce the labor intensity of the workers. The workers only need to control the welding progress, thus improving the comfort of the workers when facing the welding work. A handle 14 is fixedly provided on one side of the surface of the rotating ring 7. By rotating the rotating ring 7 through the handle 14, the welding head 8 can be easily driven to move in a ring. In this way, the welding head 8 can be used to perform ring welding work at the connection between the tube 2 and the tube sheet 1. The inclined surfaces of the first extrusion block 12 and the second extrusion block 13 are in contact with each other, such as... Figure 3 As shown, when the movable sleeve 9 moves toward the fixed plate 3, the first pressing block 12 presses the second pressing block 13, which causes the tension plate 6 to open in all directions. Thus, the tension plate 6 can be tensioned and fixed inside the tube 2, thereby fixing the entire device. A screwing block 15 is fixedly provided at one end of the threaded sleeve 11, which allows the operator to easily rotate the threaded sleeve 11. A rubber pad is provided on the outer surface of the tensioning plate 6. The rubber pad can increase the friction of the outer surface of the tensioning plate 6, thereby improving the stability of the tensioning plate 6 inside the tube 2.

[0018] Working principle: When welding tube 2 and tube sheet 1, this device can be used to directly insert tension plate 6 into tube 2. Then, rotate threaded sleeve 11 to move screw 10 and movable sleeve 9 towards fixed plate 3. At this time, under the mutual squeezing action of first squeezing block 12 and second squeezing block 13, tension plate 6 can be firmly tensioned and fixed inside tube 2. At this time, the worker can perform welding work through welding head 8 and rotate rotating ring 7 to drive welding head 8 to rotate. In this way, the device can automatically support the weight of welding head 8, which can greatly reduce the labor intensity of the worker. The worker only needs to control the welding progress, thus improving the comfort of the worker when facing welding work. Furthermore, this device is easy to operate. The tensioning and anti-loosening of the tensioning plate 6 are controlled by the rotation of the threaded sleeve 11. The welding progress can then be manually controlled by rotating the rotating ring 7. This ease of operation makes it convenient for widespread use.
