Embodiment Construction

[0016] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0017] like figure 1 As shown, a circular seam automatic welding equipment includes a positioning mechanism and a welding mechanism, wherein the positioning mechanism includes a machine base 3, a positioning motor 4 arranged on the machine base 3, and 6 sets of crank slider mechanisms, and 6 sets of crank slider mechanisms It includes three slider-crank mechanisms 6 at 120° to each other. The positioning motor 4 drives each slider-crank mechanism 6 to move synchronously along the radial direction of the base 3, that is, each slider-crank mechanism 6 moves along the radial direction of the base 3. The speed of the radial movement of the tube 1 is a...

Abstract

The invention discloses an automatic circular-seam welding device. The automatic circular-seam welding device is characterized by comprising a positioning mechanism and a welding mechanism, wherein the positioning mechanism comprises a machine base, a positioning motor and a slider-crank mechanism set, the positioning motor and the slider-crank mechanism set are arranged on the machine base, the slider-crank mechanism set comprises three slider-crank mechanisms, a 120-degree angle is formed between every two adjacent slider-crank mechanisms, and the positioning motor drives all the slider-crank mechanisms to move synchronously in the radial direction of the machine base; the welding mechanism comprises a welding-gun support located in the center of the slider-crank mechanism set, a transverse rod is arranged on the welding-gun support, and a welding gun for circular-seam welding is arranged at the other end of the transverse rod. The automatic circular-seam welding device is suitable for circular-seam welding satisfying the conditions that the variation range of diameters of pipes is large and the pipes cannot be rotated, achieves rapid positioning and accurate welding, has the advantages of being automatic, efficient and good in welding effect, and can be adapted to various different pipes by adjusting the lengths of the slider-crank mechanisms.

Description

technical field [0001] The invention relates to a circular seam automatic welding equipment. Background technique [0002] The welding of large-diameter steel pipes and flat plates belongs to circular seam welding. Due to the large size of the workpiece, it is not suitable for rotation. Usually, large-scale positioners or welding robots are equipped to realize automatic welding of circular seams. The investment is large and the preparatory work is complicated; or manual The method to complete the welding of this type of circular seam, the manual welding workload is large, the efficiency is low, and the welding quality is difficult to guarantee. Contents of the invention [0003] The object of the present invention is to provide an automatic circular seam welding device, which is suitable for circular seam welding where the pipe diameter varies widely and the pipe cannot be rotated. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-me...
