Butt welding tooling for flat workpieces

Abstract

The invention provides a butt-joint tool of a flat workpiece, which solves the problems of difficulty in guaranteeing the consistency of butt-joint area positions of different workpieces and inconvenience in operation when butt joint is performed on the flat workpiece by adopting an existing butt-joint tool. The butt-joint tool comprises an index plate, a support plate, a middle plate and a bottom plate, wherein the index plate, the support plate, the middle plate and the bottom plate are arranged in sequence from top to bottom; an electrode is vertically installed in an electrode installation groove, the upper end of the electrode passes through the support plate, a vertical shaft hole is formed in the middle of the support plate, a bushing is in interference installation in the vertical shaft hole, a lower shaft body of a rotating shaft passes through the bushing, the lower shaft body is in clearance fit with the bushing, an annular convex block which is coaxial with the index plate is integrally formed on the bottom surface of the index plate, and the upper end of the rotating shaft is rotatably connected with the annular convex block by virtue of a rolling bearing; a reset spring sleeves the outer side of the annular convex block; and a rotary pin bracket is vertically installed on the upper end of the support plate, and a rotary pin passes through the rotary pin bracket so as to position the index plate.

Description

technical field [0001] The invention relates to the technical field of butt welding equipment, in particular to a flat workpiece butt welding equipment. Background technique [0002] Butt welding is to use the high-temperature arc generated when the positive and negative poles are short-circuited instantly to melt the two materials to be welded, and apply pressure to squeeze them to achieve the purpose of combining them. When performing butt welding on a flat workpiece, it is necessary to perform multiple butt welding on the edge of the workpiece along the circumference of the workpiece. However, in the process of butt welding the flat workpiece with the existing butt welding tool, the workpiece remains still and needs to be rotated two times. The position of the electrode is not only difficult to ensure the consistency of the welding position between different workpieces, but also inconvenient to operate.
