[0002] Round pipes are a common structural element, widely used in construction, engineering and industry. Welded flanges can provide good sealing performance and structural strength. Therefore, some round pipes usually need to be used with flanges when in use, which requires the round pipe and flange to be welded together. Round pipe flange welding is a method of connecting round pipes and flanges by welding, which is widely used in the installation of equipment such as pipeline systems, valve connections, pumps and compressors. In order to ensure the strength of the round pipe or to meet the use requirements in certain situations, wing plates are also required to be welded on the outer circle of some round pipes.

The same was true for the welding of reinforcement ribs and wing plates on the outer circle of round tubes. There were problems such as low welding efficiency and heavy manual labor. The welding quality was completely dependent on the technical level of the welders, resulting in inconsistent appearance and strength of the welded components, and it was impossible to achieve standardized production of products and it was difficult to meet market requirements.

[0038] See also Figure 1-8In one embodiment of the utility model, the support mechanism may include a support frame 12, a roller frame 13, a clamping assembly, a positioning rod 14, etc. Among them, the support frame 12 is fixedly arranged, and may be fixedly arranged on the ground or other structures. A base is fixedly arranged on the support frame 12; the number of the bases may be two, which are respectively used to install the roller frame 13 and carry the two ends of the pipeline to ensure the stability of the pipeline. The roller frame 13 is connected to the base, and the roller frame 13 includes two roller rods set at an angle and a connecting part located below. The lower ends of the two roller rods are fixedly connected by the connecting part, and the roller frame 13 is connected to the base through the connecting part. A roller is rotatably arranged at one end of the roller rod away from the base, and the axes of the two rollers on the same roller frame 13 are parallel; the two rollers set on the two roller rods set at an angle are used to carry the round pipe, so that the pipeline has good centering and positioning, and is convenient for rotation and displacement. The clamping assembly is used to clamp and fix the flange; the clamping assembly may include a clamping seat, a power source and a rotating disk are provided on the clamping seat, and the power source is driven to connect the rotating disk, two clamping blocks and a movable block are fixedly provided on the rotating disk, the center angle of the part clamped between the two clamping blocks is less than °, the movable block is in the fan-shaped area outside the fan-shaped area clamped by the two clamping blocks, that is, the line connecting the two clamping blocks and the center of the rotating disk divides the rotating disk into two parts, the movable block is arranged in the part with the larger center angle, and the center angle of the fan-shaped area clamped by the movable block and any clamping block is not greater than °. The movable block is connected to a linear drive structure to drive the movable block to approach or move away from the center position of the rotating disk, so as to cooperate with the two clamping blocks to complete the fixing action of the flange. The linear drive structure may be a screw drive structure or other linear drive structures. The side of the clamping block close to the center of the rotating disk is arc-shaped, so that it can better cooperate with the outer circle of the round tube and ensure the stability of the round tube clamping.

It is used to prevent the flange from slipping out. Specifically, the center angle of the two clamping blocks can approach °, and the movable block is close to one clamping block, and forms a center angle of ° with the other clamping block. In this way, while ensuring the stability of the flange clamping and fixing, after the movable block is retracted, it is convenient for the flange to be placed and slipped out from the notch in the area with a larger center angle.

[0039] See also Figure 1-8In one embodiment of the utility model, the positioning rod 14 is movably connected to the support frame 12, and the end of the positioning rod 14 away from the support frame 12 is fixedly connected with a horizontally arranged positioning plate, and the side of the positioning plate can contact the pipe placed on the roller frame 13. Preferably, the side of the positioning plate is located at the tangent position between the vertical plane and the round pipe and contacts the round pipe. The positioning plate corresponds to the position of the wing plate to be welded on the pipe. By setting the positioning plate, it can be used for positioning when welding and adding wing plates. Initially, the wing plate can be placed on the positioning plate and contacted with the round pipe for spot welding. After welding a positioning plate, the round pipe is rotated at a fixed angle to weld the next wing plate. The rotation direction is the direction in which the welded wing plate is away from the positioning plate, so there is no need to avoid. When avoidance is needed, since the positioning rod 14 is movably set, it can be avoided by moving the positioning rod 14. After the round pipe is rotated and transposed, the wing plate that has been spot welded can be subsequently welded by the welding gun 3.

[0040] See also Figure 1-8 In one embodiment of the utility model, the specific connection mode of the positioning rod 14 can be: a mounting seat is fixedly provided on the support frame 12, the positioning rod 14 is rotatably connected to the mounting seat, and a power assembly connected to the positioning rod 14 is also provided on the mounting seat. The power assembly can be a linear motor, a cylinder or an elastic member, etc. The force provided by the power assembly enables the positioning plate to fit on the side wall of the round tube. When the power assembly is an elastic member, the positioning plate is overlapped with the surface of the round tube by elastic force, and the position of the positioning rod 14 is changed by overcoming the elastic force when avoiding. When the power assembly is an active device, it can be controlled by setting a corresponding control system. A limit block is fixedly provided on the mounting seat, and a notch matching the positioning rod 14 is provided on the limit block. The limit block can be used to limit the extreme position of the positioning rod 14 to avoid excessive squeezing of the round tube and affect the welding accuracy. At the same time, a certain plastic cushion layer can be provided to prevent the positioning plate from having too strong an impact on the round tube and causing the round tube to fall off during the reset process after the positioning rod 14 avoids.

[0041] See also Figure 1-8 In one embodiment of the utility model, the connection portion of the roller frame 13 can be rotatably connected to the base through a rotating shaft, and a power assembly for driving the roller frame 13 to rotate is provided on the base. The power assembly can be a pneumatic or hydraulic telescopic structure 7. After the round pipe is welded, the roller frame 13 is driven by the power assembly to rotate and flip around the rotating shaft, thereby completing the automatic unloading of the welded round pipe.

[0042] See also Figure 1-8In one embodiment of the utility model, the support mechanism further includes a clamping assembly, which includes a connecting frame 15, which is fixedly arranged on the supporting column, and a telescopic assembly is arranged thereon, and a pressing plate 16 is arranged at the free end of the telescopic assembly, and the contraction assembly can be a cylinder. The pressing plate 16 and the rotating disk are respectively located at both ends of the round tube. When the round tube needs to be fixed, the pressing plate 16 is pressed against the end of the round tube by contracting the telescopic assembly to complete the clamping and fixing of the round tube.

[0043] The working principle of this utility model:

[0044] First, place the workpiece round tube on the roller frame 13, and drive the pressure plate 16 to press the end of the round tube through the contraction component, and cooperate with the rotating disk at the other end to complete the compression and fixation of the round tube. After the spot welding action of the wing plate is completed manually (this process can be assisted by the positioning plate to improve the accuracy), the welding gun 3 is driven by the linear drive component 2 to move to the weld position between the wing plate and the round tube. The first welding needs to adjust the position of the welding gun 3 through the slide 6, the slider 8, the telescopic structure 7, etc., and control the distance between the welding wire and the weld to meet the standard. During the welding process, the welding gun 3 as the telescopic structure 7 can be used to drive the welding gun 3 away from and close to the weld. After debugging, the welding action is completed by driving the welding gun 3 to move through the linear drive component 2. The required welding length and welding position can be controlled by the servo motor of the linear drive component 2. Subsequent wing plates of the same model do not need to be debugged again, and can be directly welded.

[0045] The present application is applicable to the welding of round tube wing plates, and is particularly applicable to the disconnection welding of wing plates or rib plates that have been spot welded. By driving the welding gun 3 to move through a linear drive structure, semi-automatic welding of wing plates can be achieved, reducing labor intensity and labor costs, reducing requirements for operators, and ensuring the performance and appearance of the welding position and the welding consistency between different products. At the same time, the present device has a simple structure and is easy to install, which can avoid repeated replacement of welding fixtures, reduce welding costs, and improve welding efficiency.
