Automatic tracking seam welding/cutting manipulator

Abstract

The invention belongs to the technical field of a welding machine, and particularly relates to a creeping-type automatic tracking seam welding machine, which is characterized in that: a slide plate which can move transversely along a base is arranged on the base, a compression spring is arranged between the slide plate and the base, the slide plate is provided with a slide platform which moves longitudinally along the slide plate, a compression spring is arranged between the slide plate and the slide platform, the slide platform is provided with a cantilever, one side on the outer end part of the cantilever is provided with a roller which rolls along an annular seam of a work-piece to be welded, a welding torch is arranged on the cantilever at one side of the roller, a joint line of centers of the welding torch and of the roller is parallel to a central line in the length direction of the cantilever, and one side of the line of centers of the welding torch and the roller is provided with a press block or a press wheel for pressing one side welding element or an outer layer welding element. The automatic tracking seam welding / cutting manipulator has beneficial effects that: the automatic tracking seam welding / cutting manipulator has a simple structure and low production cost, is convenient to install, repair and use, can automatically track a seam trace to realize the movable welding, has high welding quality, and is suitable for seam welding annular weld seams.

Description

technical field [0001] The invention belongs to the technical field of welding auxiliary equipment, in particular to an automatic tracking full seam seam seam welding / cutting manipulator. Background technique [0002] At present, there are roughly two welding methods for non-standard circular seams on circular metal tanks in the society: one is the general method: when welding the same model, first fix the welding torch frame to a position suitable for welding circular seams, The welder changes the torch head according to the trajectory of the seam. Disadvantages: the speed of the tank body is fast, the eyes and hands are difficult to synchronize, the welding effect is not ideal, there are many waste products, and there is a lot of air leakage (poor welding leads to leakage at the weld seam that can be repaired locally) Gas), labor and time-consuming, especially when welding thin materials, the welding workers have higher technical requirements; the other is laser positionin...

[0002] At present, there are roughly two welding methods for non-standard circular seams on circular metal tanks in the society: one is the general method: when welding the same model, first fix the welding torch frame to a position suitable for welding circular seams, The welder changes the torch head according to the trajectory of the seam. Disadvantages: the speed of the tank body is fast, the eyes and hands are difficult to synchronize, the welding effect is not ideal, there are many waste products, and there is a lot of air leakage (poor welding leads to leakage at the weld seam that can be repaired locally) Gas), labor and time-consuming, especially when welding thin materials, the welding workers have higher technical requirements; the other is laser positioning welding robot: it needs to scan while moving the welding torch head by computer control, the disadvantage is that the structure is complex, The cost of production equipment is high (each needs more than 200,000 yuan), the operation is difficult, and the maintenance is difficult
