Alien tank inclined joint automatic welding machine

Abstract

The invention discloses an alien tank inclined joint automatic welding machine, comprising a fixed support fixedly connected with an installation plane, wherein the fixed support is provided with a welding gun moving mechanism capable of driving a welding gun to move vertically and move horizontally left and right; the welding gun moving mechanism is provided with a welding gun travelling mechanism; the welding gun travelling mechanism is provided with an up-and-down trim holder which is provided with a guide shaft; a guide block is arranged on the guide shaft and is provided with a welding gun adjusting mechanism capable of enabling the welding gun to move horizontally back and forth; the welding gun adjusting mechanism is provided with the welding gun; and an automatic tracking mechanism is arranged on the welding gun. The welding gun can move back and forth, left and right as well as vertically up and down, has the moving track confined to one plane, and can move in a three-dimensional space, thus the automatic welding machine can accurately weld the inclined joint or other irregular weld joints; and since the support of the automatic welding machine is fixed, the automatic welding machine can reduce the influence on the moving accuracy of the welding gun caused by the movement or rocking of the support to the greatest extent, thereby improving the welding quality. The automatic welding machine has the advantages of concise and compact structure, low manufacturing cost and simple and convenient use.

Description

technical field [0001] The invention relates to an automatic oblique seam welding machine for special-shaped tank bodies. Background technique [0002] Existing tank body welding machine has following deficiencies: the first, existing tank body seam welding machine can only weld straight seam, and straight seam refers to the seam where the cross section of seam is perpendicular to the long axis direction of tank body, But can't weld oblique seam, its main reason is, because the torch of existing welding machine can only move in two axis directions of horizontal left and right and vertical up and down, its range of movement is a vertical plane perpendicular to the long axis of tank body, And can't move on the axial direction perpendicular to the described vertical plane, that is, the welding torch can't move back and forth horizontally along the long axis direction of the tank body, therefore, can't weld oblique seam; The brackets are all walking frames installed on the gui...

[0002] Existing tank body welding machine has following deficiencies: the first, existing tank body seam welding machine can only weld straight seam, and straight seam refers to the seam where the cross section of seam is perpendicular to the long axis direction of tank body, But can't weld oblique seam, its main reason is, because the torch of existing welding machine can only move in two axis directions of horizontal left and right and vertical up and down, its range of movement is a vertical plane perpendicular to the long axis of tank body, And can't move on the axial direction perpendicular to the described vertical plane, that is, the welding torch can't move back and forth horizontally along the long axis direction of the tank body, therefore, can't weld oblique seam; The brackets are all walking frames installed on the guide rails and can move along the guide rails. During the welding process, the brackets move and shake relative to the guide rails in a large range, and the welding accuracy is low.
