[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0030] In modern industrial manufacturing, pipelines serve as crucial transmission media, widely used in construction, petroleum, natural gas, chemical, and other fields. With the rapid development of industrial automation, higher demands are placed on the precision, efficiency, and quality of pipeline welding. Traditional manual welding methods suffer from drawbacks such as inconsistent welding quality and low efficiency, making them unsuitable for the needs of modern industrial production.

[0031] In particular, efficiency is a significant issue. During welding operations, after a welding robot completes welding one pipe, it must wait for workers to remove the pipe and place another pipe back on the workstation before it can continue welding. During this time, the welding robot remains idle, failing to fully utilize its capabilities and impacting work efficiency. Therefore, this paper proposes a robot-based dual-station intelligent pipe welding device to overcome these shortcomings.

[0032] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a dual-station intelligent pipe welding device.

[0033] This embodiment provides a dual-station intelligent pipe welding device, such as... Figure 1 As shown, the welding device includes a support plate 1 and a fixed worktable 2. The support plate 1 can slide relative to the fixed worktable 2. The feature is that a welding robot is rotatably mounted on the support plate 1. The fixed worktable 2 includes a first station and a second station. The welding robot can process the workpieces at the first station and the second station.

[0034] By setting up two fixed workbenches 2 and placing the welding robot between the two fixed workbenches 2, the welding robot can continuously perform welding work, reducing working intervals and improving work efficiency. At the same time, a lead screw and a movable base 15 are set at the bottom of the support plate 1, so that the device can weld the pipes more comprehensively.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the dual-station intelligent pipe welding device also includes a transmission mechanism 5, which is located between the first station and the second station and is connected to the support plate 1. The transmission mechanism 5 is used to make the support plate 1 slide relative to the fixed worktable 2 to adjust the position of the welding robot.

[0036] Furthermore, such as Figure 1 As shown, the support plate 1 is located between the first station and the second station, and the bottom of the support plate 1 is provided with a movable base 15. The movable base 15 is slidably connected to the fixed worktable 2. The transmission mechanism 5 is a lead screw, and the movable base 15 is sleeved and threadedly connected to the outer wall of the lead screw.

[0037] Furthermore, such as Figure 1 As shown, the dual-station intelligent pipe welding device also includes a drive mechanism 4, which is located on the outer wall of the fixed workbench 2 and connected to the transmission mechanism 5. The drive mechanism 4 is used to drive the support plate 1 to slide relative to the fixed workbench 2 to adjust the position of the welding robot.

[0038] In this embodiment, the welding guns used by the welding robot are MAG welding gun 10 and TIG welding gun 11. The purpose is to be able to weld workpieces of different materials. In addition, a control cabinet 6 is provided at one end of the top of the mobile platform. A MAG welding power source is provided on the side of the control cabinet 6 near the support platform, and a TIG welding power source is provided on the side of the support platform away from the MAG welding power source.

[0039] In this embodiment, a mounting bracket 7 is fixedly installed on the top surface of the support plate 1, and a mounting platform 9 is fixedly installed on the top of the mounting bracket 7. There are two mounting brackets 7 and two mounting platforms 9. The MAG welding gun 10 and TIG welding gun 11 are respectively placed on the top surface of the two mounting platforms 9. Two welding gun power supplies 8 are fixedly installed on the top surface of the support plate 1. The two welding gun power supplies 8 are respectively connected to the MAG welding gun 10 and the TIG welding gun 11. That is to say, in actual operation, the operator can select the appropriate welding gun according to the actual needs. The purpose is to be able to weld workpieces of different materials.

[0040] In practice, when using a welding robot to weld pipes, workers can control the robot via control cabinet 6 to weld different parts of the pipe. However, in actual operation, the welding robot's welding range is limited and cannot fully cover long pipes. In this case, workers can control a lead screw via a servo motor to rotate, thereby moving the control cabinet 6, which is threaded onto the outer wall of the lead screw, along the length of the pipe. The welding robot is mounted on the top surface of the support plate 1, and the control cabinet 6 is fixedly connected to the bottom of the support plate 1. Therefore, under the power of the servo motor, the welding robot can move within the base plate 3, thus covering most of the pipe and making the welding work more comprehensive and effective. After the pipe welding is completed, workers usually need to unload the pipe and re-clamp the pipe to be welded. At this time, a conventional welding robot would be idle, unable to fully utilize its effectiveness, and delaying work efficiency. In this practical application, after completing the welding of one pipe, workers can weld the pipe above the fixed workbench 2 on the other side, achieving seamless connection of continuous welding work by the welding robot and improving overall work efficiency.

[0041] Furthermore, the welding robot includes a robot body 12 and a welding torch, which are detachably connected via a quick-change mechanism. In practical implementation, since each type of pipe has different materials and welding requirements, different welding heads are typically used when the welding robot faces different pipes. Normally, the welding head is directly fixed to the top of the welding robot, making it inconvenient to replace and unable to quickly adapt to different steel pipe materials. Therefore, the quick-change mechanism enables the welding robot to change the welding torch, further improving the robot's practicality and adaptability.

[0042] Furthermore, such as Figure 1 and Figure 3 As shown, the quick-change mechanism includes a first connector 14 and a second connector 13. The first connector 14 can be sleeved on the outside of the second connector 13. One of the first connector 14 and the second connector 13 is installed on the robot body 12, and the other is installed on the welding torch. A limiting member 143 is provided on the first connector 14. The limiting member 143 can slide radially along the first connector 14 and engage with the outer wall of the second connector 13 to lock the first connector 14 and the second connector 13. By setting the first connector 14 and the second connector 13 to enable quick replacement, and by setting the first connector 14 and the second connector 13 on the robot body 12 and the welding torch respectively, the welding robot can quickly complete the replacement of the MAG welding torch 10 and the TIG welding torch 11, reducing the replacement time, improving the overall work efficiency, and ensuring the welding quality. In addition, the welding robot can quickly adapt to different welding conditions without replacing the entire welding system, thus greatly enhancing its adaptability and practicality.

[0043] In addition, the first joint 14 and the second joint 13 can be configured as hollow structures, and a structure that facilitates welding can also be provided inside the hollow structure, without specific limitations.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, a limiting sleeve 141 is fitted on the outer wall of the first connector 14. The limiting sleeve 141 has a protrusion. The limiting sleeve 141 can slide relative to the first connector 14 so that the protrusion presses against the limiting member 143 and engages the limiting member 143 with the outer wall of the second connector 13, thereby locking the first connector 14 and the second connector 13.

[0045] Furthermore, the outer wall of the second connector 13 is provided with a snap-fit ​​groove, and the limiting member 143 can extend into the snap-fit ​​groove to lock the first connector 14 and the second connector 13.

[0046] Furthermore, the limiting sleeve 141 is also provided with a relief groove, and the limiting member 143 can enter the relief groove to unlock the first connector 14 and the second connector 13.

[0047] Furthermore, a reset member is provided between the limiting sleeve 141 and the first connector 14. One end of the reset member abuts against the protrusion, and the other end abuts against the first connector 14, so that the limiting sleeve 141 can be automatically reset.

[0048] Specifically, see Figure 4 A protrusion is provided on the outer wall of the first connector 14, and a protrusion is also provided on the inner wall of the limiting sleeve 141. A return spring 144 is connected between the two protrusions. A mating cavity 142 is provided inside the first connector 14 to accommodate the second connector 13.

[0049] Optionally, such as Figure 4 and Figure 5 As shown, the aforementioned limiting member 143 is configured as a limiting ball, which is relatively easy to install and has a relatively simple structure. In addition, the spherical limiting ball can withstand a large load, and the surface of the limiting ball is smooth, which helps to reduce friction, thereby further improving the stability of the ball and the life of the guide rail. In order to cooperate with the limiting ball, multiple circular through grooves with larger upper and smaller lower are provided on the inner wall of the first connector 14. The aforementioned limiting ball is installed inside the circular through grooves. The snap-fit ​​groove on the second connector 13 is also set as a circular groove to facilitate the snap-fit ​​of the limiting ball.

[0050] By setting the first joint 14 and the second joint 13, the welding robot in the device can quickly replace the MAG welding torch 10 and the TIG welding torch 11, reducing the replacement time and improving the overall work efficiency and ensuring the welding quality. In addition, the welding robot can quickly adapt to different welding conditions without replacing the entire welding system, thus greatly enhancing its adaptability and practicality.

[0051] Specifically, in this embodiment, by installing a first connector 14 at the top of the welding robot and a second connector 13 at the top of the MAG welding torch 10 and the TIG welding torch 11, the welding robot can quickly dock with the MAG welding torch 10 and the TIG welding torch 11. During the process, the first connector 14 abuts against the docking cavity 142 opened inside the second connector 13. Before the first connector 14 is fully inside the docking cavity 142, the operator needs to move the limiting sleeve 141 backward so that the protrusion installed on the inner wall of the limiting sleeve 141 no longer restricts the limiting bead. At this time, the edge of the limiting cavity 131 opened on the outer wall of the first connector 14 directly abuts against the limiting bead. The limiting bead is pushed upward and then falls into the interior of the limiting cavity 131. At this time, the operator releases the limiting sleeve 141, and the elasticity of the reset member will push the limiting sleeve 141 back to its original position, thereby restricting the limiting bead again. At the same time, the limiting cavity 131 is controlled by the limiting bead, so the first connector 14 cannot easily detach from the second connector 13.

[0052] Optionally, the reset component is configured as a reset spring 144, one end of which abuts against the limiting sleeve 141 and the other end of which abuts against the outer wall of the first connector 14. After the second connector 13 is inserted, the limiting sleeve 141 is automatically reset, and the protrusion on the limiting sleeve 141 abuts against the limiting component 143, so as to realize the re-locking of the first connector 14 and the second connector 13.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
