The equipment includes a platform, a mounting shell fixedly connected to the inner surface of the platform, a side plate fixedly connected to the inner surface of the mounting shell, a gear ring movably connected to the inner surface of the side plate, and a first servo motor fixedly mounted on the right surface of the mounting shell. The other end of the output shaft of the first servo motor passes through the mounting shell and extends to the left surface of the mounting shell. By setting up the side plate, gear ring, round shaft, gear, and ring, when the operator starts the first servo motor, the round shaft and gear begin to rotate.

This avoids the drawback of traditional welding methods that require rotating the pipes, effectively improving the welding accuracy of the pipes.

Description

Technical Field

[0001] This utility model relates to the field of pipe welding device technology, and more specifically, to a welding equipment for improving the welding accuracy of pipes. Background Technology

[0002] Pipeline welding is a process that achieves permanent connection between pipes by melting them at high temperatures. During welding, the welding material must be compatible with the base material. Currently, common pipeline welding methods include manual electric arc welding and tungsten inert gas welding, which is one of the core technologies for pressure pipeline engineering such as oil and gas transportation and chemical plants.

[0003] When operators perform pipe welding outdoors, they often use welding equipment to weld two sections of pipe together. However, while existing welding equipment has basic welding functions, it generally requires operators to continuously rotate the pipe to be welded during the welding process to complete the circumferential welding. During the rotation, the two pipes may have uneven rotation, resulting in low welding accuracy. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a welding equipment to improve the welding accuracy of pipes, which has the advantage of not requiring the pipe to be rotated.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for improving the welding accuracy of pipes, comprising a platform, an inner surface of which is fixedly connected to a mounting shell, an inner surface of which is fixedly connected to a side plate, an inner surface of which is movably connected to a gear ring, a first servo motor fixedly mounted on the right surface of the mounting shell, the other end of the output shaft of the first servo motor penetrating the mounting shell and extending to the left surface of the mounting shell, a gear fixedly sleeved on the outer surface of the first servo motor, a gear ring meshing with the outer surface of the gear, and circular rings located inside the side plate fixedly connected to both sides of the gear ring.

[0006] As a preferred embodiment of this utility model, an mounting plate is fixedly connected to the inner surface of the gear ring, a hydraulic cylinder is fixedly connected to the outer surface of the mounting plate, an mounting block is fixedly connected to the bottom end of the hydraulic cylinder, and a welding torch is fixedly mounted on the inner surface of the mounting block.

[0007] As a preferred embodiment of this utility model, the lower surface of the platform is fixedly connected with four support columns, all of which are of the same size.

[0008] As a preferred embodiment of this utility model, fixed clamping blocks are fixedly connected to both the left and right sides of the upper surface of the platform, and movable clamping blocks are movably connected to the upper surface of the fixed clamping blocks.

[0009] As a preferred embodiment of this utility model, a telescopic rod is fixedly connected to the lower surface of the movable clamping block, and the bottom end of the telescopic rod passes through the fixed clamping block and the platform in sequence and extends to the bottom of the platform and is fixedly connected to a connecting plate.

[0010] As a preferred embodiment of this utility model, a second servo motor is fixedly installed on the lower surface of the platform, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the second servo motor.

[0011] In a preferred embodiment of this invention, a cylinder is movably connected to the inner surface of the rotating shaft, and the cylinder is fixedly connected to the outer surface of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a side plate, a gear ring, a round shaft, a gear, and a circular ring, allows the round shaft and gear to start rotating when the operator starts the No. 1 servo motor. The rotation of the gear drives the gear ring, which in turn causes the entire gear ring to rotate under the constraint of the side plate and the circular ring. During this process, the welding torch rotates around the weld seam of the two pipes. This avoids the drawback of needing to rotate the pipes in traditional welding and effectively improves the welding accuracy of the pipes.

[0013] 2. This utility model, by setting a fixed clamping block, a movable clamping block, a cylinder, a rotating shaft, and a driving rod, when the second servo motor is started, the rotating shaft and the driving rod will start to rotate. The inner surface of the driving rod will drive the cylinder during the rotation, thereby causing the cylinder, connecting plate, telescopic rod, and movable clamping block to move downward. Finally, the movable clamping block will clamp the pipe with the cooperation of the fixed clamping block, thereby ensuring the stability of the pipe during the welding process.

[0016] 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.

[0017] like Figures 1 to 6 As shown, this utility model provides a welding device for improving the welding accuracy of pipes, including a platform 1, a mounting shell 2 fixedly connected to the inner surface of the platform 1, a side plate 3 fixedly connected to the inner surface of the mounting shell 2, a gear ring 4 movably connected to the inner surface of the side plate 3, a first servo motor 5 fixedly mounted on the right surface of the mounting shell 2, the other end of the output shaft of the first servo motor 5 passing through the mounting shell 2 and extending to the left surface of the mounting shell 2, a gear 7 fixedly sleeved on the outer surface of the first servo motor 5, a gear ring 4 meshing with the outer surface of the gear 7, and circular rings 8 located inside the side plate 3 fixedly connected to both the left and right sides of the gear ring 4.

[0018] When the operator starts the first servo motor 5, the circular shaft 6 and gear 7 will start to rotate. The rotation of gear 7 will drive the gear ring 4, thereby causing the gear ring 4 to rotate as a whole under the constraint of the side plate 3 and the ring 8.

[0019] The inner surface of the gear ring 4 is fixedly connected to the mounting plate 9, the outer surface of the mounting plate 9 is fixedly connected to the hydraulic cylinder 10, the bottom end of the hydraulic cylinder 10 is fixedly connected to the mounting block 11, and the inner surface of the mounting block 11 is fixedly mounted with the welding gun 12.

[0020] When the hydraulic cylinder 10 is activated, the mounting block 11 will begin to extend and retract, thereby bringing the welding torch 12 closer to and further away from the pipe.

[0021] Among them, the lower surface of the platform 1 is fixedly connected with four support columns 13, and the four support columns 13 are the same size.

[0022] The design of support column 13 serves to support the entire platform 1.

[0023] Among them, fixed clamping blocks 14 are fixedly connected to both the left and right sides of the upper surface of the platform 1, and movable clamping blocks 15 are movably connected to the upper surface of the fixed clamping blocks 14.

[0024] The design of the fixed clamp 14 and the movable clamp 15 serves to fix the pipe.

[0025] The lower surface of the movable clamping block 15 is fixedly connected to a telescopic rod 16. The bottom end of the telescopic rod 16 passes through the fixed clamping block 14 and the platform 1 in sequence and extends to the bottom of the platform 1 and is fixedly connected to a connecting plate 17.

[0026] The design of the telescopic rod 16 allows the movable clamping block 15 to move up and down as a whole.

[0027] The second servo motor 19 is fixedly installed on the lower surface of the platform 1, and the other end of the output shaft of the second servo motor 19 is fixedly sleeved with a rotating shaft 20.

[0028] When servo motor 19 is running, the rotating shaft 20 will start to rotate.

[0029] The inner surface of the rotating shaft 20 is movably connected to a cylinder 18, and the outer surface of the cylinder 18 is fixedly connected to the connecting plate 17.

[0030] The design of the cylinder 18 allows the rotation of the rotating shaft 20 to drive the connecting plate 17, thereby enabling the connecting plate 17 to move up and down.

[0031] Working principle and usage process of this utility model: First, the operator places the two pipes inside the fixed clamp 14, aligning the weld seams of the two pipes with the welding torch 12. Then, the operator starts the second servo motor 19. As the second servo motor 19 runs, the rotating shaft 20 and the driving rod 21 begin to rotate. The inner surface of the driving rod 21 drives the cylinder 18 during rotation, causing the cylinder 18, connecting plate 17, telescopic rod 16, and movable clamp 15 to move downwards. Finally, the movable clamp 15 clamps the pipes with the fixed clamp 14, thus ensuring their stability.

[0032] At this time, the operator starts the first servo motor 5, the hydraulic cylinder 10 and the welding torch 12. The operation of the first servo motor 5 will cause the round shaft 6, the gear 7 and the gear ring 4 to start rotating as a whole. The operation of the hydraulic cylinder 10 will cause the mounting block 11 and the welding torch 12 to move closer to the weld. When the welding torch 12 approaches the weld, the start of the welding torch 12 can weld the pipe. Finally, under the combined action of the gear ring 4, the hydraulic cylinder 10 and the welding torch 12, the welding operation of the pipe is completed.
