Description

Technical Field

[0001] This utility model belongs to the field of pipeline welding technology, and in particular relates to an automatic alignment boiler pipeline welding device. Background Technology

[0002] In the field of boiler pipe welding, there have long been many challenges. For welding pipes of different diameters, traditional clamping methods often have significant limitations. In the past, many welding operations relied on a combination of manual operation and simple mechanical structures to clamp the pipes. When encountering pipes of different diameters, it was necessary to frequently change clamps or make complex manual adjustments. This not only wasted a lot of time and reduced welding efficiency, but also made it difficult to ensure high-precision alignment by manual adjustment, which could easily lead to welding deviations, affect welding quality, and potentially cause safety hazards during boiler operation, such as leaks. Therefore, an automatic alignment boiler pipe welding device is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic alignment boiler pipe welding device. Specifically, a clamping assembly is provided, where a dual-axis motor drives a rotating shaft to rotate. This rotation is achieved through a sliding groove and a convex strip, which in turn drives a bushing to rotate. The bushing synchronously drives a drive gear and a limiting ring. The drive gear meshes with a gear ring, causing it to rotate stably along a sliding groove. The gear ring drives two driven gears to rotate synchronously, which in turn drives a rack to move towards each other. The rack pushes a clamping plate to achieve rapid positioning and clamping of the pipe. This invention solves the problem that many welding operations rely on a combination of manual operation and simple mechanical structures to clamp pipes. When encountering pipes of different diameters, frequent clamp changes or complex manual adjustments are required. This not only wastes a lot of time and reduces welding efficiency, but manual adjustments also cannot guarantee high-precision alignment, easily leading to welding deviations, affecting welding quality, and potentially causing safety hazards during boiler operation, such as leaks.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic alignment boiler pipe welding device, including a workbench that provides a stable support foundation for the entire device, and also includes: A docking mechanism is provided on the top of the workbench. The docking mechanism enables the rapid fixing and docking of pipes through clamping and adjustment. The workbench has a motor bracket welded to its top, and several slide rails are provided on the left and right sides of the top of the workbench.

[0005] Furthermore, the docking mechanism includes a drive assembly, the power source of which is connected to the motor bracket, and the drive assembly provides power output to the fixed pipeline; A clamping assembly, wherein the clamping assembly is connected to the output end of a drive assembly, and the clamping assembly achieves fixed clamping of the pipe through the drive assembly; and A movable component, which abuts against the worktable, is used to adjust the movement of the clamping component. The clamping assembly consists of two sets, which are respectively located on the left and right sides of the top of the worktable, and the two sets of clamping assemblies contain the same components.

[0006] Furthermore, the drive assembly includes a dual-axis motor, the outer surface of which is connected to the top of the motor bracket. The left and right output ends of the dual-axis motor are both connected to rotating shafts via couplings. The components connected to the two rotating shafts are identical, and two sliding grooves are formed on the outer surface of the rotating shaft on the left side.

[0007] Furthermore, a bushing is provided on the outer surface of the rotating shaft, and two protrusions are welded to the inner wall of the bushing. The outer surfaces of the two protrusions are slidably connected to the inner wall of the slide groove. A limit ring is welded to the outer surface of the bushing, and a drive gear is welded to the side of the bushing away from the dual-axis motor. A limit bracket is provided on the side of the drive gear close to the dual-axis motor. The limiting bracket is rotatably connected to the outer surface of the bushing, and a limiting groove is formed inside the limiting bracket. The inner wall of the limiting groove is rotatably connected to the outer surface of the limiting ring.

[0008] Furthermore, the clamping assembly located on the left side includes a gear ring, the outer surface of which meshes with the outer surface of the driving gear. The driving gear is disposed on the front of the gear ring, and a plurality of driven gears are meshed with the outer surface of the gear ring. The plurality of driven gears are arranged in two sets, and the two sets of driven gears are internally connected by a shaft. A plurality of fixing blocks are arranged between the two sets of driven gears, and the interior of each of the fixing blocks is rotatably connected to the shaft. Among them, racks are meshed on the outer surfaces of several driven gears away from the gear ring, and clamps are welded to the corresponding sides of several racks. The sides of several clamps away from the racks are provided with anti-slip features.

[0009] Furthermore, the moving component includes a motor connected to the left side of the worktable, and the right output end of the motor is connected to a bidirectional threaded rod via a coupling. The left and right sides of the outer surface of the bidirectional threaded rod are rotatably connected to the bottom of the worktable.

[0010] Furthermore, the left and right sides of the outer surface of the bidirectional threaded rod are threaded with support frames, both of which pass through the slide rail and extend to the top of the workbench. The legs on both sides of the two support frames are slidably connected to the inside of the slide rail on both sides. The two support frames are each welded to the top of a support sleeve. The outer ring of each support sleeve is provided with a second sliding groove. The inner ring of each second sliding groove is rotatably connected to the inner ring of the gear ring. The inner ring of each support sleeve is slidably connected to the outer surface of several racks. The front of each support sleeve is welded to the back of the limiting bracket. The outer surface of each support sleeve is welded to several fixing blocks.

[0011] This utility model has the following beneficial effects: 1. This utility model, through the setting of a clamping component, specifically, uses a dual-axis motor to drive the rotating shaft to rotate. The shaft sleeve is driven to rotate through the first sliding groove and the convex strip. The shaft sleeve synchronously drives the drive gear and the limiting ring to move. The drive gear meshes with the gear ring, causing it to rotate stably along the second sliding groove. The gear ring drives the driven gears on both sides to rotate synchronously, thereby driving the rack to move towards each other. The rack pushes the clamping plate to achieve rapid positioning and clamping of the pipe. It can adapt to pipes of different diameters, reduce the frequency of manual clamp changes, and the synchronous movement of multiple clamping plates improves the pipe docking accuracy, improves welding quality and boiler operation safety.

[0012] 2. This utility model features a moving component, specifically a motor-driven bidirectional threaded rod that rotates. This rotation, via a support frame, causes two support sleeves to move in opposite directions. The support sleeves, through the cooperation of a limiting ring and a limiting groove, cause the bushing to slide along the rotating shaft (with the sliding groove and the convex strip providing auxiliary guidance). Simultaneously, the support sleeves drag the pipe to move synchronously, achieving rapid docking and adaptive clamping. This design supports precise positioning and welding of pipes of different lengths, significantly improving the equipment's versatility.

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.

[0018] Please see Figures 1-6As shown, this utility model is an automatic alignment boiler pipe welding device, including a workbench 111, which provides a stable support foundation for the entire device. It also includes a docking mechanism 2, which is located on top of the workbench 111. The docking mechanism 2 achieves rapid fixing and docking of pipes through clamping and adjustment. A motor bracket 112 is welded to the top of the workbench 111. Several slide rails 113 are provided on the left and right sides of the top of the workbench 111. The docking mechanism 2 includes a drive assembly 21, whose power source is connected to the motor bracket 112, providing power output for fixing the pipes. A clamping assembly 22 is also included, connected to the output end of the drive assembly 21. The clamping assembly 22 is configured to fix and clamp the pipe via the drive assembly 21. A moving assembly 23 abuts against the worktable 111 and is used to adjust the movement of the clamping assembly 22. There are two sets of clamping assemblies 22, located on the left and right sides of the top of the worktable 111, respectively. Both sets of clamping assemblies 22 contain identical components. The drive assembly 21 includes a dual-axis motor 219, whose outer surface is connected to the top of the motor bracket 112. The left and right output ends of the dual-axis motor 219 are connected to rotating shafts 216 via couplings. The two rotating shafts 216 contain identical components. Two sliding grooves 217 are formed on the outer surface of the left rotating shaft 216. A bushing 211 is provided on the outer surface of the rotating shaft 216. Two protrusions 218 are welded to the inner wall of the bushing 211. The outer surfaces of the two protrusions 218 are slidably connected to the inner wall of the slide groove 217. A limit ring 214 is welded to the outer surface of the bushing 211. A drive gear 213 is welded to the side of the bushing 211 away from the dual-axis motor 219. A limit bracket 212 is provided on the side of the drive gear 213 close to the dual-axis motor 219. The inside of the limit bracket 212 is rotatably connected to the outer surface of the bushing 211. A limit groove 215 is formed inside the limit bracket 212. The inner wall of the limit groove 215 is rotatably connected to the outer surface of the limit ring 214. The clamping assembly 22 on the left side includes a gear ring 221. The outer surface of the gear ring 221 meshes with the outer surface of the drive gear 213. Next, the driving gear 213 is located on the front of the gear ring 221. Several driven gears 224 are meshed on the outer surface of the gear ring 221. These driven gears 224 are arranged in two sets, internally connected by shafts. Several fixing blocks 225 are positioned between the two sets of driven gears 224, each internally rotatably connected to the shaft. A rack 226 is meshed on the outer surface of several driven gears 224 furthest from the gear ring 221. A clamping plate 222 is welded to the corresponding side of each rack 226. The side of the clamping plate 222 furthest from the rack 226 is designed for anti-slip. The dual-axis motor 219 drives the rotating shaft 216 to rotate, which in turn drives the bushing 211 to rotate via the sliding groove 217 and the protrusion 218.The bushing 211 synchronously drives the drive gear 213 and the limiting ring 214 to move. The drive gear 213 meshes with the gear ring 221, causing it to rotate stably along the sliding groove 223. The gear ring 221 drives the driven gears 224 on both sides to rotate synchronously, which in turn drives the rack 226 to move towards each other. The rack 226 pushes the clamping plate 222 to achieve rapid positioning and clamping of the pipe. It can adapt to pipes of different diameters, reduce the frequency of manual clamp changes, and the synchronous movement of multiple clamping plates 222 improves the pipe docking accuracy, welding quality, and boiler operation. For safety, the moving component 23 includes a motor 233, which is connected to the left side of the worktable 111. The right output end of the motor 233 is connected to a bidirectional threaded rod 234 via a coupling. The left and right sides of the outer surface of the bidirectional threaded rod 234 are rotatably connected to the bottom of the worktable 111. The left and right sides of the outer surface of the bidirectional threaded rod 234 are threadedly connected to support frames 232. Both support frames 232 pass through the slide rail 113 and extend to the top of the worktable 111. The supports on both sides of the two support frames 232 are... The legs are slidably connected to the slide rails 113 on both sides. Each of the two support frames 232 has a support sleeve 231 welded to its top. The outer ring of each support sleeve 231 has a second slide groove 223, which is rotatably connected to the inner ring of the gear ring 221. The inner ring of each support sleeve 231 is slidably connected to the outer surface of several racks 226. The front of each support sleeve 231 is welded to the back of the limiting bracket 212. The outer surface of each support sleeve 231 is connected to several fixing blocks 225. In the welding process, motor 233 drives the bidirectional threaded rod 234 to rotate, which in turn drives the two support sleeves 231 to move in opposite directions via support frame 232. The support sleeves 231, through the cooperation of limiting ring 214 and limiting groove 215, cause bushing 211 to slide along shaft 216 (with guide groove 217 and protrusion 218). Simultaneously, the support sleeves 231 drag the pipe to move synchronously, achieving rapid docking and adaptive clamping. This design supports precise positioning and welding of pipes of different lengths, significantly improving the equipment's versatility.

[0019] A specific application of this embodiment is as follows: In use, firstly, two pipes are placed inside the support sleeve 231, and then the dual-axis motor 219 is started to drive the two rotating shafts 216 to rotate. When the rotating shafts 216 rotate, they will drive the bushing 211 to rotate through the action of the first sliding groove 217 and the protrusion 218. During the rotation of the bushing 211, the drive gear 213 will rotate. At the same time, during the rotation of the bushing 211, the limiting ring 214 will rotate inside the limiting groove 215. Meanwhile, the limiting bracket 212 provides a certain support force for the bushing 211 by being fixedly connected to the support sleeve 231. During the rotation of the bushing 211, the gear ring 221 will rotate through the action of the drive gear 213. When the gear ring 221 rotates, its inner ring will rotate inside the second sliding groove 223. The second sliding groove 223 provides a certain stability for the movement trajectory of the gear ring 221. During the process, several driven gears 224 away from the rack 226 will rotate. At this time, the driven gears 224 will drive several driven gears 224 on the other side to rotate through the action of the shaft. The driven gears 224 will drive several racks 226 to move closer to each other. During the process of the racks 226 moving closer to each other, they will slide inside the support sleeve 231. At the same time, the racks 226 will drive several clamping plates 222 to move together, thereby achieving the positioning and clamping of the pipe. It can be used to clamp and fix pipes of various diameters, reducing the need for operators to frequently change clamps, thereby improving work efficiency. At the same time, the synchronous movement of multiple clamping plates 222 clamps and fixes the pipe. Compared with the traditional manual adjustment of clamps by operators, it improves the accuracy of pipe docking, thereby improving welding quality and reducing the safety hazards during boiler operation. Simultaneously, after the two pipes are fixedly clamped, the start motor 233 drives the bidirectional threaded rod 234 to rotate. During the rotation of the bidirectional threaded rod 234, it drives the two support sleeves 231 to move closer or further apart through the two support frames 232. At this time, during the movement of the two support sleeves 231, the bushing 211 will move together through the action of the limiting ring 214 and the limiting groove 215. At this time, the bushing 211 will slide on the outer surface of the rotating shaft 216 through the action of the protrusion 218 and the sliding groove 217. When the two support sleeves 231 move, they will drive the pipes to move together, which makes it easier for the operator to connect the pipes and also makes it easier to clamp and weld pipes of different lengths, further improving the versatility of the equipment.
