Profile buckle structure automatic welding machine with shape positioning

Abstract

The invention discloses an automatic welding machine for conformal positioning of a profile buckle structure, including a welding mechanism with a welding machine and a welding torch, a displacement positioning mechanism and a welding torch fixing mechanism; the displacement positioning mechanism includes a supporting plate, a connecting plate, and a connecting seat, and the top of the supporting plate is installed There is a welding machine, and both ends of the support plate are provided with a horizontal support shaft, and one end of the support shaft body is rotatably connected with a fixed end wheel. The present invention proposes an automatic welding machine for profile buckle structure conformal positioning. The displacement positioning mechanism of the welding machine has fixed wheels and moving wheels. The moving wheels can move and adjust by themselves according to the tension of the tension spring, which is suitable for buckle profiles. The change of the width and straightness of the profile, the change of the distance between the wheels through the size deviation of the profile, the tension of the tension spring will cause the slight movement of the connecting sleeve, and then the welding torch will move slightly to reach the center of the seam and the melting of the welding wire during the welding process. The center of the pool always maintains a consistent purpose.

Description

technical field [0001] The invention relates to the technical field of welding of structural parts, in particular to an automatic welding machine for conformal positioning of profile buckle structures. Background technique [0002] The profile butt welding form is a commonly used form of crane rod structure. This structure can weld two or more profiles of the same type (or different types) into one component. This structure is relatively different from the panel structure. , can effectively reduce the weight of structural parts, increase its mechanical performance, reduce welding deformation, and reduce production costs. [0003] Commonly used structures include direct buckle and intermediate splint. Since most of the profiles are supplied in a hot-rolled state, there are certain errors in the width of the flange and the accuracy of the straight line. After the profile is assembled, the width dimension and the straight line There is a certain deviation in the degree of weld...

[0003] Commonly used structures include direct buckle and intermediate splint. Since most of the profiles are supplied in a hot-rolled state, there are certain errors in the width of the flange and the accuracy of the straight line. After the profile is assembled, the width dimension and the straight line There is a certain deviation in the degree of welding. Since the center of the seam needs to be consistent with the center of the welding wire molten pool during welding, the welding path needs to be corrected in real time according to the position of the seam. Currently, the welding methods used are manual welding and rail-type trolley welding. In the two forms, manual welding is inefficient and labor-intensive; during the welding process of track-type trolley, trolley tracks need to be laid frequently, and the welding position cannot be corrected in real time, which may easily cause the center of the joint seam and the center of the welding wire molten pool to be inconsistent.
