Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, and more specifically to a welding bracket. Background Art

[0002] Announcement No. CN218776005U proposes a pipe welding bracket. At present, in the process of horizontal fixed welding of pipe fittings, the existing technology first horizontally empties two pipe fittings that need to be welded through the bracket, and then fixes the pipe fittings to be welded by the clamp on the bracket after adjusting the position. Finally, the welder holds the welding equipment around the butt ends of the two pipe fittings for welding. However, at present, the clamp for fixing the pipe fittings is generally set to a shape that matches the pipe fittings, such as the clamp corresponding to the round pipe is set to an arc shape, so as to better support and fix the round pipe, but this clamp can only adapt to the round pipe alone, and cannot play a good fixing role when welding the square pipe. By setting it on the lower fixing piece, the lower fixing piece has a rotatable support block, the support block is a rectangular block and its two opposite sides are provided with arc placement grooves, by adjusting the position of the support block, the square pipe is placed through the plane side of the support rod, and the round pipe is placed in the arc placement groove to adapt to the welding clamping and fixing of two common pipe fittings, no need to replace the clamp, simple structure, easy operation.

[0003] However, the angle of the fixing part in the above device is fixed, which can only ensure the welding of two pipes at right angles. Some pipes need to be bent for welding. At this time, the welding surface is an inclined surface, which is not convenient for aligning the inclined surface after fixing. Therefore, we propose a welding bracket that is easy to adjust the angle. Utility Model Content
