Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, and in particular to an automated pipe welding device. Background Technology

[0002] Pipe welding (welding between main pipe and branch pipe, i.e., welding a smaller diameter branch pipe to a larger diameter main pipe) is a welding method that uses an electric arc as a heat source to connect pipes through gas shielded welding or gas electric welding. This welding method uses gas as a protective medium. During the welding process, the protective gas forms a protective layer around the electric arc, separating the electric arc and molten pool from the air, preventing the influence of harmful gases, and ensuring stable combustion of the electric arc.

[0003] Currently, pipe welding is usually carried out by manually aligning the branch pipe with the notch of the main pipe. However, since the side wall of the main pipe and the end face of the branch pipe near the main pipe are both curved surfaces (i.e., non-planar), manual support can easily cause the branch pipe to shift relative to the notch of the main pipe, making it difficult to align the branch pipe with the notch of the main pipe. This affects the welding quality and efficiency of the pipe. In addition, manual support is time-consuming and labor-intensive, which will further affect the welding efficiency of the pipe. Utility Model Content

[0004] To address the shortcomings of existing production technologies, the applicant provides an automated welding device based on pipe bodies. By improving the structure of the automated welding device based on pipe bodies, precise alignment of the branch pipe body with the notch of the main pipe body is achieved, and no misalignment occurs after alignment, thereby improving the welding quality and efficiency of the pipe body.

[0005] The technical solution adopted in this utility model is as follows: An automated welding device based on a pipe body includes: a base, two first fixing mechanisms, multiple second fixing mechanisms, multiple third fixing mechanisms, and multiple alignment mechanisms. The two first fixing mechanisms are located on both sides of the base and are used together to fix the main pipe to be welded. The multiple second fixing mechanisms are located between the two first fixing mechanisms and are slidably connected to the base. The third fixing mechanisms correspond one-to-one with the alignment mechanisms. The multiple third fixing mechanisms and the multiple alignment mechanisms are located on both sides of the second fixing mechanisms and are slidably connected to the second fixing mechanisms. The alignment mechanism is rotatably connected to the second fixing mechanism. The third fixing mechanism is used to fix the branch pipe to be welded and to move the branch pipe closer to or further away from the main pipe. The alignment mechanism is used for positioning the branch pipe and the notch in the main pipe.

[0006] Therefore, by first positioning the notch of the main pipe through the alignment mechanism, and then aligning the notch of the branch pipe with the notch of the main pipe through the third fixing mechanism, the automated welding operation between the branch pipe and the main pipe can be realized. Compared with the existing manual support method, this method has a simple structure and is easy to operate. By positioning first and then aligning, the branch pipe can be accurately aligned with the notch of the main pipe, and there will be no offset after alignment, thereby improving the welding quality and welding efficiency of the pipe.

[0007] As a further improvement to the above technical solution: the first fixing mechanism includes a fixing block, two semi-circular arc-shaped fixing plates, and two first locking members. The fixing block is connected to the base, the two semi-circular arc-shaped fixing plates are arranged opposite to each other, the semi-circular arc-shaped fixing plates are rotatably connected to the fixing block, and the two semi-circular arc-shaped fixing plates are connected by the first locking members. Thus, the two semi-circular arc-shaped fixing plates are fixed together by the first locking members, thereby fixing the main body to be welded, preventing relative sliding between the branch pipe and the main body, and preventing displacement between the branch pipe and the main body.

[0008] As a further improvement to the above technical solution: the second fixing mechanism includes a first fixing component and two second locking members. The two second locking members are respectively located on both sides of the first fixing component. The first fixing component is slidably connected to the base, and the second locking members pass through the first fixing component and are threadedly connected to the first fixing component. Thus, the second fixing mechanism slides relative to the base, allowing adjustment of the position of the branch pipe relative to the main pipe according to different models of main pipes, thereby enabling welding operations on different models of main pipes. The first fixing component and the second locking members can perform a double locking operation to enhance the alignment accuracy of the branch pipe.

[0009] As a further improvement to the above technical solution: the first fixing component has the same structure as the first fixing mechanism.

[0010] As a further improvement to the above technical solution: the third fixing mechanism includes a first fixing ring, a second fixing component, and two third locking members. The first fixing ring is sleeved on the second fixing mechanism via a support rod and is slidably connected to the second fixing mechanism, allowing the first fixing ring to move closer to or further away from the second fixing mechanism. The second fixing component is installed on one side of the first fixing ring, and the third locking members pass through the other side of the first fixing ring and are threadedly connected to the first fixing ring. Thus, the third fixing mechanism secures the branch pipe body, ensuring that during the pipe welding process, the branch pipe body will not shift after being aligned with the notch of the main pipe body.

[0011] As a further improvement to the above technical solution: the second fixing component has the same structure as the first fixing mechanism.

[0012] As a further improvement to the above technical solution: the alignment mechanism includes a second fixing ring, a third fixing ring, and a positioning rod. The second fixing ring is sleeved on the second fixing mechanism via the support rod and is slidably connected to the second fixing mechanism, allowing the second fixing ring to move closer to or further away from the second fixing mechanism. The third fixing ring is sleeved on the second fixing ring and is rotatably connected to the second fixing ring. The positioning rod is mounted on the third fixing ring; the positioning rod is adapted to the notch of the main pipe body. Thus, by adjusting the rotation of the positioning rod around the axial direction of the second fixing ring and adjusting the movement of the positioning rod closer to the second fixing mechanism, the positioning rod can be inserted into the notch of the main pipe body, thereby achieving the positioning operation before the branch pipe body is aligned.

[0013] As a further improvement to the above technical solution, the alignment mechanism is located between the second fixing mechanism and the third fixing mechanism. Therefore, this design, where the alignment mechanism is located between the second and third fixing mechanisms, ensures that the positioning operation and the alignment operation of the branch pipe do not interfere with each other.

[0014] As a further improvement to the above technical solution, it also includes: a welding robot and a welding gun. The welding robot is mounted on the base and is located on the side of the alignment mechanism away from the third fixing mechanism. The welding gun is mounted on the drive end of the welding robot and is used for welding the notch between the branch pipe and the main pipe. Thus, the welding robot drives the welding gun to move, and the welding operation of the notch between the branch pipe and the main pipe is achieved through the welding gun.

[0015] As a further improvement to the above technical solution: two welding robots are provided, and each welding gun corresponds to one welding robot. Thus, the cooperation between the two welding robots and the two welding guns enables the welding of the branch pipes on both sides of the main pipe.

[0016] The beneficial effects of this utility model are as follows: The alignment mechanism first positions the notch in the main pipe, and then the third fixing mechanism aligns the notch in the branch pipe with the notch in the main pipe to achieve automated welding between the branch pipe and the main pipe. Compared with the existing manual support method, this method has a simple structure and is easy to operate. By positioning first and then aligning, the branch pipe can be accurately aligned with the notch in the main pipe, and there will be no offset after alignment, thereby improving the welding quality and welding efficiency of the pipe.

[0017] This utility model also has the following advantages: 1. The second fixing mechanism of this utility model slides relative to the base, and can adjust the position of the branch pipe relative to the main pipe according to different models of main pipe, so as to realize the welding operation of different models of main pipe; the first fixing component and the second locking component can perform double locking operation to enhance the alignment accuracy of the branch pipe.

[0018] 2. This utility model adjusts the positioning rod by rotating it around the second fixing ring in the axial direction and by moving it closer to the second fixing mechanism, so as to insert the positioning rod into the notch of the main pipe body. In this way, the positioning operation before the branch pipe body is aligned can be realized.

[0019] 3. The alignment mechanism of this utility model is located between the second and third fixing mechanisms, which ensures that the positioning operation of the branch pipe and the alignment operation of the branch pipe do not interfere with each other. Attached Figure Description

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figures 1 to 9 The diagram shows the preferred embodiment of this utility model. The automated welding device based on the pipe body in this embodiment includes: a base 1, two first fixing mechanisms 2, multiple second fixing mechanisms 3, multiple third fixing mechanisms 4, and multiple alignment mechanisms 5. The two first fixing mechanisms 2 are located on both sides of the base 1, and the two first fixing mechanisms 2 are used together to fix the main pipe to be welded. The multiple second fixing mechanisms 3 are located between the two first fixing mechanisms 2 and are slidably connected to the base 1. The third fixing mechanisms 4 and the alignment mechanisms 5 correspond one-to-one. The multiple third fixing mechanisms 4 and the multiple alignment mechanisms 5 are located on both sides of the second fixing mechanisms 3, and the third fixing mechanisms 4 and the alignment mechanisms 5 are slidably connected to the second fixing mechanisms 3. The alignment mechanism 5 is rotatably connected to the second fixing mechanism 3. The third fixing mechanism 4 is used to fix the branch pipe to be welded and to move the branch pipe closer to or further away from the main pipe. The alignment mechanism 5 is used for positioning the branch pipe and the notch of the main pipe. Therefore, by first positioning the notch of the main body through the alignment mechanism 5, and then aligning the notch of the branch pipe with the notch of the main body through the third fixing mechanism 4, the automated welding operation between the branch pipe and the main body can be realized. Compared with the existing manual support method, this method has a simple structure and is easy to operate. By positioning first and then aligning, the branch pipe can be accurately aligned with the notch of the main body, and there will be no deviation after alignment, thereby improving the welding quality and welding efficiency of the pipe.

[0024] In this embodiment, the first fixing mechanism 2 includes: a fixing block 201, two semi-circular arc-shaped fixing pieces 202, and two first locking members 203. The fixing block 201 is connected to the base 1. The two semi-circular arc-shaped fixing pieces 202 are arranged opposite to each other and are rotatably connected to the fixing block 201. The two semi-circular arc-shaped fixing pieces 202 are connected by the first locking members 203. Thus, the two semi-circular arc-shaped fixing pieces 202 are fixed together by the first locking members 203, thereby fixing the main body to be welded, and preventing relative sliding between the branch pipe and the main body, and preventing displacement between the branch pipe and the main body.

[0025] For example, the first locking element 203 uses a bolt.

[0026] In this embodiment, the second fixing mechanism 3 includes a first fixing component 301 and two second locking members 302. The two second locking members 302 are located on both sides of the first fixing component 301. The first fixing component 301 is slidably connected to the base 1, and the second locking members 302 pass through the first fixing component 301 and are threadedly connected to the first fixing component 301. The first fixing component 301 has the same structure as the first fixing mechanism 2. Thus, the second fixing mechanism 3 slides relative to the base 1, and can adjust the position of the branch pipe relative to the main pipe according to different models of main pipes to realize welding operations of different models of main pipes. The first fixing component 301 and the second locking members 302 can perform a double locking operation to enhance the alignment accuracy of the branch pipe.

[0027] It should be noted that the double locking operation refers to: first, the locking operation in which the first fixing component 301 is fixed to the main body; second, the locking operation in which the first fixing component 301 is fixed to the base 1 through the second locking component 302. Such a double locking operation can improve the stability of the branch pipe relative to the main body, thereby enhancing the alignment accuracy of the branch pipe.

[0028] For example, the second locking element 302 uses a bolt.

[0029] In this embodiment, the third fixing mechanism 4 includes a first fixing ring 401, a second fixing component 402, and two third locking members 403. The first fixing ring 401 is sleeved on the second fixing mechanism 3 via a support rod 6 and is slidably connected to the second fixing mechanism 3, allowing the first fixing ring 401 to move closer to or further away from the second fixing mechanism 3. The second fixing component 402 is installed on one side of the first fixing ring 401, and the third locking members 403 pass through the other side of the first fixing ring 401 and are threadedly connected to the first fixing ring 401. The second fixing component 402 has the same structure as the first fixing mechanism 2. Thus, the third fixing mechanism 4 is used to fix the branch pipe body to ensure that during the pipe welding operation, the branch pipe body will not shift after being aligned with the notch of the main pipe body.

[0030] For example, the third locking element 403 uses bolts.

[0031] In this embodiment, the alignment mechanism 5 includes a second fixing ring 501, a third fixing ring 502, and a positioning rod 503. The second fixing ring 501 is sleeved on the second fixing mechanism 3 via a support rod 6 and is slidably connected to the second fixing mechanism 3, allowing the second fixing ring 501 to move closer to or further away from the second fixing mechanism 3. The third fixing ring 502 is sleeved on the second fixing ring 501 and is rotatably connected to the second fixing ring 501. The positioning rod 503 is mounted on the third fixing ring 502; the positioning rod 503 is adapted to the notch of the main pipe body. Thus, by adjusting the rotation of the positioning rod 503 around the axial direction of the second fixing ring 501 and adjusting the movement of the positioning rod 503 closer to the second fixing mechanism 3, the positioning rod 503 can be inserted into the notch of the main pipe body, thereby achieving the positioning operation before the branch pipe body is aligned.

[0032] In this embodiment, the alignment mechanism 5 is located between the second fixing mechanism 3 and the third fixing mechanism 4. Therefore, the design of the alignment mechanism 5 being located between the second fixing mechanism 3 and the third fixing mechanism 4 ensures that the positioning operation and the alignment operation of the branch pipe do not interfere with each other.

[0033] In this embodiment, the system further includes a welding robot 7 and a welding gun 8. The welding robot 7 is mounted on the base 1 and is located on the side of the alignment mechanism 5 away from the third fixing mechanism 4. The welding gun 8 is mounted on the drive end of the welding robot 7 and is used for welding the notch between the branch pipe and the main pipe. There are two welding robots 7, and each welding gun 8 corresponds to one welding robot 7. Thus, the welding robot 7 drives the welding gun 8 to move, and the welding gun 8 is used to achieve the welding operation between the branch pipe and the main pipe. The cooperation between the two welding robots 7 and the two welding guns 8 enables the welding operation of the branch pipes on both sides of the main pipe.

[0034] The automated welding process of the pipe body of this utility model is as follows: First, the main pipe body to be welded is fixed by two first fixing mechanisms 2; then, the position of the second fixing mechanism 3 is adjusted according to the position of the notch of the main pipe body and with the cooperation of the alignment mechanism 5; then, the second fixing mechanism 3 is fixed (i.e., the locking operation of the first fixing component 301 to the main pipe body and the locking operation of the first fixing component 301 to the base 1 through the second locking component 302); finally, after the second fixing mechanism 3 is fixed, the alignment mechanism 5 is rotated 180°, and the branch pipe body is fixed on the third fixing mechanism 4, and the branch pipe body is moved to the side closer to the main pipe body so that the notch of the branch pipe body and the main pipe body are aligned. Then, the welding robot 7 drives the welding gun 8 to move, and the welding gun 8 completes the automated welding operation between the notch of the branch pipe body and the main pipe body.

[0035] In summary, this utility model first positions the notch of the main body using the alignment mechanism 5, and then aligns the branch pipe with the notch of the main body using the third fixing mechanism 4, thereby realizing automated welding between the branch pipe and the main body. Compared with the existing manual support method, this method has a simple structure and is easy to operate. By positioning first and then aligning, the branch pipe can be accurately aligned with the notch of the main body, and there will be no offset after alignment, thereby improving the welding quality and welding efficiency of the pipe.
