Description

Technical Field

[0001] The utility model relates to the technical field of girth welding, in particular to a multi-directional girth welding welding head. Background Art

[0002] Circumferential welding refers to the welding of various circular and annular welds, and the welded weld is a closed circular ring. This welding method is common in the connection parts of circular structures such as pipes and containers, because their shape determines that continuous welding along the circumference is required during welding. However, when welding pipes, due to its manual welding method, there is often a stagnation in the welding process, which leads to welding interruption and affects the welding quality. Therefore, a multi-directional circular welding head is needed.

[0003] The application number retrieved is: CN202022955006.8, a multi-welding head synchronous positioning mechanism for an automatic welding machine for internal circumferential seams of pipelines, which has good fixing effect, strong versatility and is easy to use and operate.

[0004] However, the existing circumferential welding still has certain defects in actual use: when welding the pipe body, there is often a stagnation in the welding process, which leads to welding interruption and affects the welding quality. At the same time, when welding both sides of the pipeline, it is often necessary to weld the pipe body on one side and then repeat the welding on the other side of the pipeline. Therefore, the welding process is often cumbersome and the position of the welding head needs to be readjusted. For this reason, we propose a multi-directional circumferential welding head.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] The welding assembly 6 includes a connecting plate 23, a vertical slide rail 24, a control room 25, a sliding bracket 26, a welding head 27, a welding guard plate 28 and a welding baffle 29, and two sets of vertical slide rails 24 are arranged on the left side of the connecting plate 23, and a control room 25 is arranged at the center of the two sets of vertical slide rails 24, and a sliding bracket 26 is arranged on the side of the two sets of vertical slide rails 24 away from the connecting plate 23, and a welding head 27 is arranged on the side of the sliding bracket 26 away from the two sets of vertical slide rails 24, and a welding guard plate 28 is installed on the side of the two sets of welding heads 27 away from the sliding bracket 26, and the two sets of welding guard plates 28 A welding baffle 29 is installed at the bottom by bolts. At this time, the vertical slide rail 24 of the welding component 6 drives the sliding bracket 26 to move upward, so that the welding component 6 can be welded with pipes of different diameters. At this time, two sets of slide rails are installed inside the sliding bracket 26, and the two sets of slide rails are respectively installed with the welding head 27. Therefore, when welding the pipe body, pipe welding at different distances can be achieved. The welding guard plate 28 at the head of the welding head 27 and the welding baffle block the welding impurities in the welding process, thereby preventing the welding head 27 from contacting with impurities and causing blockage.

[0023] The conveying assembly 8 includes a driving motor 18, a supporting base 19, a conveying bracket 20, a lifting bracket 21, a rotating shaft 22 and a gear, and a supporting base 19 is arranged below the driving motor 18, and the conveying bracket 20 is installed on both sides of the supporting base 19 by bolts, and the lifting bracket 21 is installed on both sides of the conveying bracket 20, and the rotating shaft 22 is inserted at the center of the two groups of lifting brackets 21, and the outer surface of the rotating shaft 22 is installed with a gear, and the conveying assembly 8 is installed by the internal toothed belt connected to the output end of the driving motor 18 and the gear on the rotating shaft 22, so that its driving motor 18 drives the rotating shaft 22 to rotate, so that when the rotating shaft 22 rotates, the lifting bracket 21 connected to the rotating shaft 22 will lift and move the tube body above the conveying bracket 20, thereby moving the tube body to the top of the rotating assembly 10.

[0024] The locking assembly 7 includes a fixed base 11, a fixed bracket 12, an electric push rod 13, an extrusion block 14 and a rotating disk 1401, and a fixed bracket 12 is installed above the fixed base 11, and an electric push rod 13 is installed on the top of the fixed bracket 12 by bolts, and an extrusion block 14 is installed on the output end of the electric push rod 13 by bolts, and a rotating disk 1401 is installed on the side of the extrusion block 14 away from the electric push rod 13. At this time, when the pipe body used for welding is above the conveying assembly 8, the electric push rod 13 is pushed forward, so that the extrusion block 14 contacts the pipe body, and the rotating disk 1401 installed on the outer surface of the extrusion block 14 contacts the pipe body to extrude the pipe body. During the extrusion process, when the pipe body rotates, the rotating disk 1401 in contact with the pipe body simultaneously follows the inside of the extrusion block 14 and rotates through the bearing.

[0025] The rotating assembly 10 includes a rotating ring 15 and a connecting bracket 16, and the connecting bracket 16 is installed on both sides of the two sets of rotating rings 15. At this time, the rotating assembly 10 drives the rotating ring 15 to rotate through the motor inside the second motor chamber 17, so that the rotating ring 15 drives the pipe body to rotate, so that during the welding process, the welding position is constantly changed, thereby realizing multi-directional welding.

[0026] A support leg 2 is installed below the frame 1 by bolts, and a fixing plate 3 is installed below the support leg 2, and a support rod 4 is installed below the first motor room 5. The frame 1 is supported by the support leg 2 and the fixing plate 3, and the first motor room 5 is supported by the support rod 4 below.

[0027] In summary, the utility model uses the frame 1 and the welding assembly 6. When welding the pipe body, the welding pipe 9 is placed above the conveying bracket 20 of the conveying assembly 8. Since the conveying bracket 20 is inclined, the pipe rolls to the top of the lifting bracket 21. At this time, the driving motor 18 drives the rotating shaft 22 to rotate through the belt, and the lifting bracket 21 connected to the pipe body is driven by the rotating shaft 22 to contact the pipe body, thereby lifting the pipe body to move, so that the pipe body is moved to the top of the rotating assembly 10. At this time, the locking assemblies 7 on both sides of the rotating assembly 10 push the extrusion block 14 through the electric push rod 13, and the rotating disk 1401 of the extrusion block 14 contacts the pipe body, thereby completing To fix the pipe body, the vertical slide rail 24 of the welding assembly 6 drives the connected sliding bracket 26 to move upward, so that the welding head 27 installed on the sliding bracket 26 is above the pipe body. At this time, the welding head 27 is adjusted by the slide rail inside the sliding bracket 26, so that the welding head 27 is in the welding position. At this time, the welding head 27 welds the pipe body. During the welding process, the rotating assembly 10 drives the rotating ring 15 to rotate through the second motor chamber 17, so that the pipe body above the rotating ring 15 is continuously moved, so that the welding head 27 can continuously weld the pipe body, thereby realizing multi-directional welding of the pipe body.
