Full-automatic straight seam welding equipment

Abstract

The invention discloses full-automatic straight seam welding equipment. The full-automatic straight seam welding equipment comprises a rack, wherein a main shaft where workpieces are placed is arranged in the middle of the rack; a welding mechanism, a positioning assembly and a clamping assembly are arranged on the periphery of the main shaft, and the welding mechanism is arranged over the main shaft; the positioning assembly is at least composed of clamping mechanisms arranged on the left side and the right side above the main shaft and a positioning plate mechanism movably arranged between the clamping mechanisms on the left side and the right side; and the clamping assembly is at least composed of side edge positioning mechanisms arranged on the left side and the right side of the mainshaft. According to the full-automatic straight seam welding equipment, the positioning plate mechanism is arranged to locate the welding welding placing position of the workpieces in advance, so thatthe welding position of the workpieces is conveniently and effectively ensured; and meanwhile, the clamping mechanisms and the side edge positioning mechanisms ensure that no displacement deviation occurs when the workpieces are welded, so that the influence of the deviation on the welding effect in the welding process is avoided, the welding quality of the workpieces is effectively guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of welding processing equipment, in particular to a fully automatic straight seam welding equipment. Background technique [0002] Straight seam welding equipment is a main equipment for welding metal sheets, especially for cylindrical workpieces that have been rolled and formed at the coil level, straight seam welding equipment plays an important role. [0003] In the process of traditional straight seam welding equipment welding the cylindrical workpiece and other sheet materials rolled by the plate rolling machine, in order to avoid the deviation of the workpiece expansion and deformation during welding, the manual passing point is usually passed in advance. The welding method pre-welds the workpiece to ensure the stability of the weld seam. This method has many disadvantages such as low work efficiency and unstable spot welding quality; at the same time, in the welding process, it is easy to occur in the...

[0003] In the process of traditional straight seam welding equipment welding the cylindrical workpiece and other sheet materials after being rolled by the plate rolling machine, in order to avoid the deviation of the workpiece expansion and deformation during welding, the manual passing point is usually passed in advance. The welding method pre-welds the workpiece to ensure the stability of the weld seam. This method has many disadvantages such as low work efficiency and unstable spot welding quality; at the same time, in the welding process, it is easy to cause welding deviation and inaccurate welding. appear, thus need to rework the welding, it is difficult to guarantee the welding quality
