[0002] The utility model discloses an angle positioning device for pipeline positive and negative groove welding, which is a device used for positioning and installing the angle of pipeline during pipeline positive and negative groove welding processing.

[0003] At present, there are many angle positioning devices for pipeline yin-yang groove welding on the market, but in general, the angle positioning devices for pipeline yin-yang groove welding require workers to place the pipeline to be welded on a processing table, and the workers manually press and clamp the pipeline on the processing table, and then adjust the angle and press to weld. It is very easy for the pipeline to collide with the external welding head, causing the angle to deviate, thereby affecting the workers' normal welding of the pipeline yin-yang groove and reducing the use effect of the device.

[0004] Based on the above, the inventors found that when the staff placed the pipe to be welded on the processing table, the staff manually pressed and clamped the pipe on the processing table, and then the staff adjusted the angle and pressed to weld, it was very easy for the pipe to collide with the external welding head, causing the angle to deviate, thereby affecting the staff's normal welding of the positive and negative grooves of the pipe. Therefore, in view of this, the existing structure was studied and improved, and an angle positioning device for welding the positive and negative grooves of the pipe was provided, in order to achieve a more practical purpose.
