Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting welding, in particular to a rotatable welding tooling assembly. Background Art

[0002] When welding complex pipe fitting structures, it is usually necessary to weld in the horizontal and vertical directions of the pipe fittings. The welding tooling used can facilitate horizontal and vertical rotation and positioning. The existing rotatable welding tooling is equipped with positioning pins on a fixed base, and the rotating base has positioning angle holes. The rotating base is positioned and fixed by using a pin shaft manually at the approaching position. This rotating positioning structure has low positioning efficiency, requires manual removal of the pin and reinstallation of the tooling, and the accuracy is affected by the assembly process, resulting in low positioning accuracy. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a pipe fitting rotating welding tooling, enabling the workpiece to be welded to quickly switch between the horizontal and vertical states and maintain positioning.

[0004] To achieve the above purposes, the utility model adopts the following technical solutions:

[0005] A pipe fitting rotating welding tooling includes a support assembly and a rotating assembly. The support assembly includes a fixed bracket, a fixed rotating shaft, and a fixed cover plate. The rotating assembly includes a rotating seat, a rotating bracket, and a counterweight block. One side of the fixed rotating shaft is fixedly connected to the fixed bracket along the axial direction, and the other side is a semi-cylinder. A sector hole is provided at the center of the end face of the rotating seat. The sector hole occupies three-quarters of the circumference of the cylindrical hole, and the diameter of the sector hole is the same as that of the semi-cylinder of the fixed rotating shaft. The sector hole of the rotating seat is rotatably connected to the semi-cylinder of the fixed rotating shaft. A circular groove with the same diameter as the fixed cover plate is provided on the outer end face of the rotating seat. The circular groove is sleeved with the fixed cover plate. The fixed cover plate is detachably connected to the fixed rotating shaft. The rotating bracket is detachably connected to one end of the rotating seat close to the fixed cover plate. The rotating seat can rotate 90 degrees relative to the fixed rotating shaft. The counterweight block is arranged on the end face on the side far from the center of gravity of the rotating bracket, so that the center of gravity of the rotating bracket after installing the workpiece to be welded is within the diagonal included angle range of the sector hole of the rotating seat, thereby ensuring positioning in the vertical and horizontal states.

[0006] Further, the upper surface of the semi-cylinder of the fixed rotating shaft is a horizontal plane, enabling the rotating bracket to maintain the vertical and horizontal states.

[0007] Further, the depth of the circular groove is greater than the thickness of the fixed cover plate, so that the rotating seat will not be stuck by the fixed cover plate after being threadedly connected to the rotating bracket, thus affecting rotation.

[0008] Further, the fixed bracket includes at least three horizontal fixing rods and one vertical fixing rod. The horizontal fixing rods are perpendicular to each other in the horizontal plane, the vertical fixing rod is perpendicular to the horizontal plane, and the horizontal fixing rods and the vertical fixing rod are welded to each other, making the fixed bracket more stable.

[0009] Further, the rotating bracket is provided with a connecting plate, and mounting holes are provided at corresponding positions of the connecting plate and the rotating seat, so that the rotating seat and the rotating bracket are accurately and cooperatively connected.

[0010] Further, the rotating bracket includes rods for forming a frame and support seats and support plates for supporting welded parts. The rods are welded perpendicular to each other. There are at least three support seats. The support surface of the support seat is semi-circular, and the bottom surface is flat. The bottom surface of the support seat is welded to the rod, so that the pipe fittings to be welded can be stably fixed on the rotating bracket.

[0011] Further, a mating hole is provided below the fixed rotating shaft, and positioning holes are provided below the rotating seat in both the initial position and after rotating 90 degrees.

[0012] A pipe fitting rotating welding tooling of the present utility model realizes 90° rotation and positioning through the cooperation of a new internal structure rotating shaft and a rotating shaft seat, without manual intervention, improving the applicable efficiency of the tooling.
