Automatic welding system for header welding

Abstract

The invention discloses an automatic welding system for header welding. The automatic welding device for header welding comprises a supporting assembly, wherein the top of the supporting assembly is fixedly connected with connecting rods, and the tops of the connecting rods are fixedly connected with mounting plates. Through cooperative use of stepping motors, a transverse plate, mounting frames, welding guns, servo motors, the mounting plates, screw rods, a left clamping assembly, hydraulic cylinders, a main sleeve, branch sleeves, a right clamping assembly, a vertical plate, a driving motor, rotating discs, a positioning plate, an angle sensor, a convex block, distance measuring sensors, thread blocks, screw rods and screw blocks, the automatic welding system for header welding has the beneficial effects of being stable in clamping, capable of rotating to adjust the angle and wide in application range, and the problems that when an existing automatic welding system meets the requirement for stable clamping, angle adjusting operation cannot be conducted, lower-level pipes at different positions cannot be welded, the requirement for welding installation of the lower-level pipes of different specifications cannot be met, the application range is common, and the machining requirement of a user cannot be met are solved.

Description

technical field [0001] The invention relates to the technical field of header processing, in particular to an automatic welding system for header welding. Background technique [0002] In order to improve the efficiency of the boiler, the drum boiler has gradually developed into a tube boiler to increase the heat transfer area. The boiler water flows from the drum through the downcomer into the box below, and is distributed to the tube bundles by the box. The water in these tube bundles is continuously Absorb heat energy, collect it into the upper box and then flow back into the drum. The upper and lower boxes are called header or header. The header (also known as header) is an important part of the boiler and is divided into upper and lower boxes. Header and lower header. The header is a pipe fitting for mixing the working fluid of the boiler and ensuring uniform heating of the working fluid. The header allows the working fluid in each tube to converge here and then distrib...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic welding system for header welding, which has the advantages of stable clamping, rotation angle adjustment and wide application range, and solves the problem that the existing automatic welding system cannot meet the requirements of stable clamping. The angle adjustment operation cannot be used to weld the lower pipes in different positions, and it cannot meet the welding installation of lower pipes of different specifications. The scope of application is general and the processing needs of users cannot be met.
