Intersecting line welding seam welding equipment and method

Abstract

The invention discloses intersecting line welding seam welding equipment, comprising a main pipe and a branch pipe. The end of the branch pipe is in lap joint with the side wall of the main pipe. The intersecting line welding seam welding equipment further comprises a clamping table; the main pipe is fixed through the clamping table; the middle of the outer side wall of the branch pipe is sleeved with a fixed rotating mechanism; the outer side wall of the fixed rotating mechanism is fixedly connected with the upper portion of the clamping table; and the inner wall of the branch pipe is fixedly connected with an inner rotation measuring mechanism. By arranging a first distance measuring assembly and a second distance measuring assembly, intersecting line data with small errors can be obtained through calculation; when the measuring, cutting and welding procedures are carried out, a fixed rotating mechanism does not need to be disassembled and assembled, intersecting line data measuring, branch pipe cutting and welding are all completed on the same equipment, a welding starting point does not need to be manually positioned, and the relative position of the fixing sleeve of the fixed swing mechanism and the branch pipe is always unchanged, so that the running track of cutting and welding can completely coincide with intersecting line data, and the precision after welding is improved.

Description

technical field [0001] The invention relates to the technical field of intersecting line welding. Specifically, it is an intersecting line welding seam welding equipment and method. Background technique [0002] In welding, the welding of intersecting lines is very common, among which two pipes intersect welding is the majority. In the existing technology center, the intersecting pipes are generally cut by CNC machine tools or manually scribed. Although CNC machine tools The precision is high, but the equipment is expensive, and requires a certain factory installation, and the flexibility of use is not high, and the accuracy of manual scribing and cutting is poor, especially when the diameter of the pipe is large, it needs repeated corrections many times, which is inefficient; and in the intersecting line When welding, there are still many inconveniences. The intersecting line is a complex three-dimensional curve. When welding by a welding robot, it is necessary to locate t...

[0002] In welding, the welding of intersecting lines is very common, among which two pipes intersect welding is the majority. In the existing technology center, the intersecting pipes are generally cut by CNC machine tools or manually scribed. Although CNC machine tools The precision is high, but the equipment is expensive, and requires a certain factory installation, and the flexibility of use is not high, and the accuracy of manual scribing and cutting is poor, especially when the diameter of the pipe is large, it needs repeated corrections many times, which is inefficient; and in the intersecting line When welding, there are still many inconveniences. The intersecting line is a complex three-dimensional curve. When welding by a welding robot, it is necessary to locate the welding point, and the weld bead is prone to deviation, and the weld bead correction is difficult, resulting in a decrease in welding quality.
