[0002] In industrial production, welding of pipe fittings is a common and critical process. Especially for the welding of pipe fittings that cannot be moved and have a large diameter, traditional pipe welding methods mostly rely on manual operation, which has many disadvantages. On the one hand, the quality of manual welding is greatly affected by factors such as the operator's skill level and working status. It is difficult to ensure the consistency and stability of welding quality, and it is easy to have problems such as uneven welding and weld defects. On the other hand, manual welding is inefficient, especially for some pipe fittings that require circular welding. Operators need to constantly adjust the welding position and angle, which is labor-intensive and slow, and cannot meet the needs of large-scale production. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a track welding device that can automatically complete annular welding.

[0028] The following uses specific embodiments to illustrate the present invention, but it does not limit the invention.

[0029] Embodiment 1

[0030] As Figures 1 - 7 shown, in this embodiment, an orbital welding device is provided, including a frame 1, a guide plate 2 and a welding torch 7.

[0031] The frame 1 is a circular arc plate with an arc-shaped notch groove on one side. The frame 1 is made of a steel plate with strong rigidity, which is not easily deformed. The angle of the arc-shaped notch groove is less than 180 degrees. The first slideway 101 is arranged along the circular arc direction of the frame 1 inside the circular arc plate frame 1. The distance of the arc-shaped notch groove is greater than the diameter of the pipe fitting to be welded, which enables the frame 1 to be easily sleeved on the pipe fitting to be welded directly from the arc-shaped notch groove. The frame 1 is the basic support structure of the entire orbital welding device, providing an installation position and an operating track for other components. The material with strong rigidity ensures the stability of the device, and the arc-shaped notch groove design facilitates the rapid installation of the device onto the pipe fitting to be welded, improving work efficiency.

[0032] The guide plate 2 is slidably installed inside the first slideway 101. The second slideway 201 is arranged along the circular arc direction of the guide plate 2 inside the guide plate 2. The guide plate 2 plays a guiding role. It can slide on the first slideway 101 of the frame 1 to change its position on the frame 1, providing a movable installation basis for the welding torch 7. At the same time, the second slideway 201 inside it provides a track for the movement of the welding torch 7.

[0033] The welding torch 7 is installed inside the second slideway 201 and can move along the extending direction of the second slideway 201 inside the second slideway 201. The welding torch 7 is a component that directly performs the welding task. The second slideway 201 provides an accurate path for the movement of the welding torch 7, enabling the welding torch 7 to perform welding operations along the circumferential direction of the pipe fitting. The guiding plate 2 is slidably installed in the first slideway 101 of the frame body 1. The operator can move the guiding plate 2 on the first slideway 101 according to the actual welding requirements, adjust the position of the guiding plate 2 on the frame body 1, so as to change the initial position of the welding torch 7 to adapt to different welding starting points and welding range requirements. The welding torch 7 is installed in the second slideway 201 of the guiding plate 2. After starting the equipment, the welding torch 7 moves along the extending direction of the second slideway 201. During the movement, the welding torch 7 performs welding operations on the pipe fitting. As the welding torch 7 continuously moves on the second slideway 201, it will complete the entire welding process along the circumferential direction of the pipe fitting, realizing the circumferential welding of the pipe fitting.

[0034] Embodiment 2

[0035] As Figures 1 - 7 shown, on the basis of Embodiment 1, this embodiment provides the structure of the frame body 1, which is specifically as follows:

[0036] The frame body 1 is of a split structure. The frame body 1 includes two arc plates. The first slideway 101 is arranged between the two arc plates. A support plate 5 is fixed to the outside of the two arc plates. A relief space for the movement of the welding torch 7 is provided in the middle of the support plate 5. The setting of the support plate 5 not only enhances the overall structural strength of the frame body 1, but also the relief space provided by it provides the necessary space for the movement of the welding torch 7, ensuring that the welding torch 7 can smoothly perform welding operations. During equipment assembly, the two arc plates are combined together to form the complete frame body 1 structure, and at the same time, the guiding plate 2 is installed in the first slideway 101 between the two arc plates. The support plate 5 is fixed to the outside of the two arc plates, providing support and stability for the entire frame body 1. When the welding torch 7 moves driven by the guiding plate 2, through the relief space in the middle of the support plate 5, interference with other parts of the frame body 1 is avoided, ensuring the smooth progress of the welding process.

[0037] Both ends of the inside of the frame body 1 located at the first slideway 101 are open. The guiding plate 2 can slide outwards from the openings. The length of the guiding plate 2 is greater than the length of the arc-shaped notch. When it is necessary to install or maintain the guiding plate 2, the operator can slide the guiding plate 2 into or out of the openings at both ends of the first slideway 101. During the welding process, the guiding plate 2 can freely slide in the first slideway 101 and adjust its own position according to the welding position requirements. Due to its specific relationship with the length of the arc-shaped notch, it can cover a certain welding range and meet the welding requirements of different pipe fittings.

[0038] A plurality of screw rods 4 are threadedly connected to the two arc plates. The end of the screw rod 4 is rotatably connected to a locking plate 3. At least two of the locking plates 3 are centrosymmetric about the axis of the arc plate, so as to realize more stable locking and installation of the frame 1 outside the pipe fitting to be welded. By threadedly connecting a plurality of screw rods 4 to the two arc plates and rotatably connecting the locking plates 3 at the ends of the screw rods 4, the position of the locking plate 3 can be adjusted by rotating the screw rod 4, so as to more stably lock and install the frame 1 outside the pipe fitting to be welded. The design that at least two of the locking plates 3 are centrosymmetric about the axis of the arc plate can make the frame 1 receive uniform force on the pipe fitting, avoid loosening or shaking, and improve the stability and accuracy of welding.

[0039] The side of the locking plate 3 away from the screw rod 4 is an arc surface, and the arc surface is an anti-slip surface. When the screw rod 4 drives the locking plate 3 to move towards the surface of the pipe fitting and squeeze, the arc surface of the locking plate 3 is in close fit with the circumferential surface of the pipe fitting, increasing the contact area and making the pressure distribution more uniform. A large frictional force is generated between the anti-slip surface and the surface of the pipe fitting, effectively preventing the locking plate 3 from sliding on the surface of the pipe fitting, thus ensuring the stability of the frame 1 during the welding process and avoiding affecting the welding quality due to the shaking of the frame 1.

[0040] Embodiment Three

[0041] As Figures 1 - 7 shown, on the basis of Embodiment One and Embodiment Two, this embodiment provides the moving modes of the guide plate 2 and the welding torch 7, which are specifically as follows:

[0042] Sliding strips are provided on both sides of the guide plate 2, and chutes are provided on both side walls of the first slideway 101. The sliding strips are slidably installed inside the chutes. The sliding strips on both sides of the guide plate 2 cooperate with the chutes on both side walls of the first slideway 101 to form a sliding pair. This design makes the sliding of the guide plate 2 in the first slideway 101 more stable and accurate, can effectively reduce the shaking and deviation of the guide plate 2 during the sliding process, and ensure that the moving track of the welding torch 7 is more precise.

[0043] A first motor 9 is fixed on the arc plate, and a first gear 8 is fixed to the output end of the first motor 9. Among them, tooth teeth are provided on any one of the sliding strips, and the first gear 8 meshes with the tooth teeth on the sliding strip. When it is necessary to move the guide plate 2, the first motor 9 is started, and the first motor 9 drives the first gear 8 to rotate. Since the first gear 8 meshes with the tooth teeth on the sliding strip, the rotation of the first gear 8 will drive the sliding strip to move through the tooth tooth transmission, so that the guide plate 2 slides in the first slideway 101. By controlling the rotation speed and rotation direction of the first motor 9, the moving speed and direction of the guide plate 2 can be precisely controlled to meet different welding requirements.

[0044] The interior of the guide plate 2 is provided with a second slideway 201. The welding torch 7 is fixed on the sliding column 6, and the sliding column 6 is slidably installed inside the second slideway 201. During the welding process, when it is necessary to adjust the position of the welding torch 7, the sliding column 6 can slide within the second slideway 201 of the guide plate 2. Since the welding torch 7 is fixed on the sliding column 6, the movement of the sliding column 6 will drive the welding torch 7 to move together, thereby realizing the adjustment of the position of the welding torch 7 in the circumferential direction of the pipe fitting. The operator can manually or through other driving methods control the sliding of the sliding column 6 within the second slideway 201 according to the actual welding requirements to reach the ideal welding position.

[0045] Arc grooves are provided on the side walls of the second slideway 201, and arc strips are provided on both sides of the guide plate 2. The arc strips are slidably installed inside the arc grooves. When the sliding column 6 is installed into the second slideway 201, the arc strips on both sides of the guide plate 2 are aligned with the arc grooves on the side walls of the second slideway 201 and slid in. When the sliding column 6 slides within the second slideway 201, the arc strips slide within the arc grooves. The arc grooves play a role in restraining and guiding the arc strips, enabling the sliding column 6 to move smoothly only along the direction of the arc grooves, avoiding the shaking and deviation of the sliding column 6 within the second slideway 201, thereby ensuring that the welding torch 7 can perform welding according to the predetermined trajectory.

[0046] A second motor 9 is fixed on the sliding column 6, and a second gear 10 is installed at the output end of the second motor 9. Teeth meshing with the second gear 10 are provided inside the first slideway 101. When it is necessary to move the welding torch 7, the second motor 9 is started, and the second motor 9 drives the second gear 10 to rotate. Since the second gear 10 meshes with the teeth inside the first slideway 101, the rotation of the second gear 10 will drive the sliding column 6 to move through the tooth transmission, thereby causing the welding torch 7 to slide within the second slideway 201 of the guide plate 2. By controlling the rotation speed and direction of the second motor 9, the moving speed and direction of the welding torch 7 can be precisely controlled, realizing the precise control of the welding process.

[0047] Working principle:

[0048] Since the arc opening groove of the frame body 1 is larger than the diameter of the pipe fitting to be welded, the operator can directly put the frame body 1 on the pipe fitting to be welded from the arc opening groove. After the installation is completed, rotate the screw rods 4 threadedly connected to the two arc plates. The locking plates 3 rotatably connected to the ends of the screw rods 4 will move towards the surface of the pipe fitting. At least two locking plates 3 symmetrically centered on the axis of the arc plates can make the frame body 1 receive uniform force on the pipe fitting, firmly fixing the frame body 1 outside the pipe fitting. The anti-slip design of the arc surface on the side of the locking plate 3 away from the screw rod 4 increases the contact area and friction force with the surface of the pipe fitting, further ensuring the stability of the frame body 1.

[0049] The slide bars on both sides of the guide plate 2 cooperate with the sliding grooves on the side walls of the first slideway 101. When it is necessary to adjust the position of the guide plate 2, the first motor 9 fixed on the arc plate is started, and the first motor 9 drives the first gear 8 at the output end to rotate. Since the first gear 8 meshes with the teeth on the slide bar, the rotation of the first gear 8 will drive the slide bar to move through the tooth transmission, so that the guide plate 2 slides in the first slideway 101. By controlling the rotation speed and direction of the first motor 9, the moving speed and direction of the guide plate 2 can be accurately controlled to meet the requirements of different welding starting points and welding ranges.

[0050] The welding torch 7 is fixed on the sliding column 6, and the sliding column 6 is slidably installed in the second slideway 201 inside the guide plate 2. The arc grooves on the side walls of the second slideway 201 cooperate with the arc bars on both sides of the guide plate 2. When the sliding column 6 slides in the second slideway 201, the arc bars slide in the arc grooves to ensure the smooth movement of the sliding column 6 and avoid shaking and deviation.

[0051] When it is necessary to move the welding torch 7, the second motor 9 fixed on the sliding column 6 is started, and the second motor 9 drives the second gear 10 at the output end to rotate. Since the second gear 10 meshes with the teeth inside the first slideway 101, the rotation of the second gear 10 will drive the sliding column 6 to move through the tooth transmission, so that the welding torch 7 slides in the second slideway 201 of the guide plate 2. By controlling the rotation speed and direction of the second motor 9, the moving speed and direction of the welding torch 7 can be accurately controlled.

[0052] The welding torch 7 moves along the extension direction of the second slideway 201 and performs welding operations on the pipe fittings during the movement. As the welding torch 7 continuously moves on the second slideway 201, it will complete the entire welding process along the circumferential direction of the pipe fittings to achieve circumferential welding of the pipe fittings. At the same time, the relief space opened in the middle of the support plate 5 provides the necessary space for the movement of the welding torch 7 to avoid interference with other parts of the frame 1.
