Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline welding technology, specifically a pipeline welding device. Background Technology
[0002] In pipeline fabrication, circumferential welding is one of the key processes. Traditional manual welding requires highly skilled operators, is labor-intensive, and struggles to guarantee consistent welding quality and efficiency. To improve welding quality and automation, specialized pipeline welding machines and welding robots are increasingly being used in the market.
[0003] Existing automated welding equipment typically comprises a stationary assembly and a welding torch assembly: the stationary assembly clamps and drives the pipe to rotate, while the welding torch assembly performs the welding operation. However, in practical applications, this type of equipment still has significant limitations. On the one hand, the spatial adjustment freedom of the welding torch is often insufficient, making it difficult to quickly and accurately position it to the optimal welding posture; on the other hand, the stationary assembly can mostly only drive the pipe to rotate around its axis, and when the pipe is placed at an angle, there is a lack of a mechanism to quickly and stably adjust the tilt angle of the pipe axis, thus restricting the equipment's adaptability to diverse working conditions. Utility Model Content
[0004] In order to solve the technical problems existing in the background art, the present invention provides a pipe welding device, which can flexibly adjust the welding position and angle, effectively improve the adaptability and stability of the welding process, thereby ensuring the welding quality.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A pipe welding apparatus includes a welding assembly and a fixing assembly:
[0007] The welding components include:
[0008] Base;
[0009] The column is mounted on the base and can be moved laterally.
[0010] The movable base is mounted on the column and can be moved longitudinally.
[0011] The horizontal arm is mounted on the movable base and is perpendicular to the direction of movement of the column;
[0012] The welding torch is mounted on the horizontal arm.
[0013] The fixed components include a rotatable chuck.
[0014] Furthermore, the welding torch is connected to the cross arm via an adjustment assembly.
[0015] Furthermore, the adjustment components include:
[0016] The first adjusting element is rotatably mounted on the cross arm;
[0017] The second adjusting member is rotatably mounted on the first adjusting member and is perpendicular to the rotation direction of the first adjusting member;
[0018] The third adjusting member is rotatably mounted on the second adjusting member and is perpendicular to the rotation direction of the second adjusting member.
[0019] Furthermore, the adjustment components also include:
[0020] The first slide is fixedly mounted on the third adjusting member;
[0021] The second slide is fixedly mounted on the moving part of the first slide and is perpendicular to the first slide;
[0022] The welding torch is fixedly mounted on the moving part of the second slide.
[0023] Furthermore, the fixing components also include:
[0024] Support base;
[0025] The rotating frame is rotatably mounted on a support base and is equipped with a rotatable chuck.
[0026] The motor, mounted on the rotating frame, is used to drive the chuck to rotate.
[0027] Furthermore, a worm gear is fixedly installed on the rotating frame, and a rotatable worm is installed on the support base, with the worm gear and worm gear engaging in a transmission.
[0028] The beneficial effects of this utility model are:
[0029] (1) The welding assembly adopts a multi-layer moving structure, which combines the three rotational degrees of freedom and two linear movement degrees of freedom of the adjustment assembly, so that the welding torch can be finely adjusted in position and angle in multiple directions. This ensures that the welding torch can be quickly and accurately aligned with welds at different positions and angles, and is especially suitable for welding operations of complex spatial welds.
[0030] (2) The fixing component not only provides rotational movement around the pipe axis through the chuck, but also realizes the tilting of the chuck in the other direction through the rotating frame. This allows the pipe to be welded to be adjusted to the optimal welding posture without re-clamping, which facilitates welding of the pipe circumferential and specific angle interfaces, greatly reduces auxiliary time, and improves work efficiency.
[0031] (3) Both the welding torch and the pipeline have multi-degree-of-freedom controllable motion, and the two work together to achieve precise planning and tracking of the welding trajectory. By coordinating and controlling each motion unit, the welding torch can always maintain the ideal welding angle and relative position during the welding process, effectively reducing human operation errors and ensuring the consistency of weld formation and the stability of welding quality.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.
[0044] like Figure 1 , 2 As shown, a pipe welding device includes a welding assembly 1 for welding pipes and a fixing assembly 2 for fixing and adjusting the position of the pipes.
[0045] like Figure 3As shown, the specific structure of welding assembly 1 includes a base 101. A column 102 is movably mounted on the base 101 via guide rails. A movable seat 103 is movably mounted on the column 102 via guide rails. A horizontal arm 104 is movably mounted on the movable seat 103 via guide rails and is perpendicular to the direction of movement of the column 102. A welding torch 106 is mounted on the horizontal arm 104. The welding torch 106 is connected to the horizontal arm 104 via an adjusting assembly 105. The base 101, column 102, movable seat 103, and horizontal arm 104 form a multi-layered movable structure, thereby enabling multi-directional position adjustment of the welding torch 106.
[0046] like Figure 4 As shown, the specific structure of the adjustment assembly 105 includes a first adjustment member 1051, which is rotatably mounted on the cross arm 104. A second adjustment member 1052 is rotatably mounted on the first adjustment member 1051 and is perpendicular to the rotation direction of the first adjustment member 1051. A third adjustment member 1053 is rotatably mounted on the second adjustment member 1052 and is perpendicular to the rotation direction of the second adjustment member 1052. The first adjustment member 1051, the second adjustment member 1052, and the third adjustment member 1053 can form an adjustment structure with three degrees of rotational freedom, thereby enabling fine-tuning of the orientation and angle of the welding torch 106. A first slide 1054 is fixedly mounted on the third adjustment member 1053. A second slide 1055 is fixedly mounted on the moving part of the first slide 1054 and is perpendicular to the first slide 1054. The welding torch 106 is fixedly mounted on the moving part of the second slide 1055. The first slide 1054 and the second slide 1055 form an adjustment structure with two linear degrees of freedom, thereby fine-tuning the position of the welding torch 106.
[0047] In summary, the welding assembly 1 adopts a multi-layered moving structure, combining the three rotational degrees of freedom and two linear movement degrees of freedom of the adjustment assembly 105, enabling the welding torch 106 to be finely adjusted in position and angle in multiple directions. This ensures that the welding torch 106 can be quickly and accurately aligned with welds at different positions and angles, making it particularly suitable for welding complex spatial welds.
[0048] like Figure 5 As shown, the specific structure of the fixing component 2 includes a rotatable chuck 203, which is an existing structure used to clamp and fix the pipe. The fixing component 2 also includes a support base 201, with a rotating frame 202 rotatably mounted on the support base 201, and the chuck 203 rotatably mounted on the rotating frame 202. A motor 204 is mounted on the rotating frame 202 and is used to drive the chuck 203 to rotate. A worm gear 205 is fixedly mounted on the rotating frame 202, and a rotatable worm 206 is mounted on the support base 201, with the worm 206 and worm gear 205 engaging in a transmission connection. By rotating the worm 206, the tilt angle of the rotating frame 202 can be adjusted.
[0049] The fixing component 2 not only provides rotational movement around the pipe axis via the chuck 203, but also enables the chuck 203 to tilt in another direction via the rotating frame 202. This allows the pipe to be welded to be adjusted to the optimal welding posture without reclamping, facilitating welding of pipe circumferential and specific angle interfaces, significantly reducing auxiliary time and improving work efficiency.
[0050] With the above structure, both the welding torch 106 and the pipe have multi-degree-of-freedom controllable motion, and their cooperation can achieve precise planning and tracking of the welding trajectory. By coordinating and controlling each motion unit, the welding torch 106 can maintain an ideal welding angle and relative position throughout the welding process, effectively reducing human error and ensuring the consistency of weld formation and the stability of welding quality.
[0051] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
