description The invention belongs to the technical field of pipeline welding and discloses an external opening aligning machine for pipelines. The external opening aligning machine for the pipelines comprises a fixed clamping assembly, a movable clamping assembly, a guide rod and a horizontally-moving hydraulic cylinder. The guide rod is arranged between the fixed clamping assembly and the movable clamping assembly. The horizontally-moving hydraulic cylinder is connected with the fixed clamping assembly and the movable clamping assembly. The fixed clamping assembly comprises a first upper frame and a first lower swing arm. The first lower swing arm is hinged to the first upper frame through a hinge shaft. The movable clamping assembly comprises a second upper frame and a second lower swing arm. The second lower swing arm is hinged to the second upper frame through a hinge shaft. During opening aligning operation, the main pipeline abuts against the inner side of the first upper frame, and the first lower swing arm tightl
