Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a large-diameter round pipe welding machine for ships. Background Art

[0002] Ships refer to large water vehicles used to transport people and goods on water, usually including various types of ships, such as cargo ships, passenger ships, tankers, container ships, fishing boats, etc. In the process of ship production, large-diameter round tubes are needed. The application rate of large round tubes and large linear components is constantly increasing, and the manual time consumption of electric welding accounts for about 40%, which greatly affects the subsequent completion nodes.

[0003] After searching, a Chinese patent announcement number CN221935848U discloses a large-diameter round pipe welding machine for ships. The patent includes two bottom plates and a control box. The two bottom plates are arranged side by side, and the control box is arranged on one side of the front end of the two bottom plates. The first electric telescopic rods are arranged at the front and rear ends of one side of the upper end surface of the two bottom plates. A top plate is provided at the output end of the first electric telescopic rod on one side and the output ends of the two first electric telescopic rods on the other side. A welding machine is provided on one side of the center of the upper end surface of the top plate on one side, and two clamping structures are arranged horizontally on the upper end surfaces of the two bottom plates. A slide groove is provided on one side of the center of the upper end surfaces of the two bottom plates. The device drives the two clamping structures on both sides to adjust the position through two adjustment structures, which is convenient for welding pipes of different lengths. The clamping structure can weld pipes of different diameters and can also drive the two pipes to rotate automatically, which is convenient for welding. However, the existing large-diameter round pipe welding devices cannot adapt well to welding pieces of different lengths. If the device is too long, it will occupy a large area and make it difficult to load and unload the welded pieces. If the device is too short, the support effect on the welded pieces will be poor, resulting in uneven force on the upper and lower parts of the weld position, affecting the welding effect.

[0037] Working principle: When the device is in use, it is necessary to first adjust the position of the first movable plate 102 and the second movable plate 103 according to the length of the two ends of the round tube to be welded, start the first motor 301 and the second motor 302 to change the position of the first movable plate 102 and the second movable plate 103 by rotating the first screw 303 and the second screw 304. While ensuring that the weld is located in the middle position of the first movable plate 102, the end of the welded parts that are away from each other also needs to have a suitable support effect to avoid the occurrence of uneven annular welds due to poor support effect on one end of the welded parts, such as desoldering and weld cracking. After the adjustment is completed, the two sections of the round tube are respectively loaded between the first driving roller 401, the second driving roller 403 and the supporting roller 404. The welded parts are arranged parallel to the supporting roller 404, and the cylinder 202 is used to push the connecting seat 20 3. Make the welding head of the welding machine 204 against the welding seam position. When welding starts, start the third motor 506. The third motor 506 drives the transmission shaft 503 to rotate. The transmission shaft 503 drives the transmission rod 504 to rotate. The transmission shaft 503 and the transmission rod 504 respectively drive the first transmission gear 502 and the second transmission gear 505 to rotate. The first transmission gear 502 and the second transmission gear 505 drive the two driving gears 501 to rotate. The driving gear 501 drives the first driving roller 401 to rotate. The first driving roller 401 drives the second driving roller 403 to rotate through the plug-in block 408. When the first driving roller 401 and the second driving roller 403 rotate, the two sections of the welded parts rotate synchronously with the first driving roller 401 and the second driving roller 403. During the rotation process, the welding machine 204 welds the welding seam position of the welded parts. After one rotation, the welding is completed.
