Abstract

The invention relates to a positioning device for continuous pipeline welding. The positioning device is used for automatically positioning a spot welding position of a steel pipe completing spot welding and is characterized by comprising a left side positioning and moving assembly and a right side positioning and moving assembly; a transmitting module and a receiving module of a correlation type photoelectric sensor are arranged on the left side positioning and moving assembly and the right side positioning and moving assembly correspondingly, and a control unit controls the transmitting module and the receiving module to move synchronously in the axial direction of the steel pipe through the left side positioning and moving assembly and the right side positioning and moving assembly; in the synchronous movement process, the transmitting module and the receiving module are kept relatively static; and only when the transmitting module and the receiving module move to the spot welding position of the steel pipe, the receiving module receives an optical signal transmitted by the transmitting module. According to the positioning device for continuous pipeline welding, the spot welding position of the steel pipe can be automatically positioned, the later preheating position can be conveniently determined to ensure the preheating effect, and automatic operation of steel pipe welding can be easily achieved.

Description

technical field [0001] The invention relates to a positioning device for continuous pipeline welding, which is used for automatically positioning the spot welding position of steel pipes and relates to the technical field of automatic positioning. Background technique [0002] Preheating of the weld seam is often required before steel pipe welding. On the one hand, it prevents the heat generated during welding from causing rapid heating and rapid cooling of the metal, resulting in changes in the metallographic structure, lower strength or cracks, and avoids welding defects. On the other hand , preheating has the effect of dehydrogenation and reducing thermal stress. Therefore, the preheating of the pipeline before welding is of great significance to the welding quality. [0003] In the prior art, the steel pipes to be welded are connected by spot welding at the weld seam first, then the spot welding position is manually determined, and then the surroundings of the spot weld...
