Welding device in pipe rack processing assembly

Abstract

The invention discloses a welding tool in pipe rack processing assembly. The welding tool comprises a bottom plate, supporting columns and a transverse shaft, wherein the two sides of the top of the bottom plate are separately equipped with the supporting columns; the bottom ends of the two supporting columns are welded and fixed on the top surface of the bottom plate; the transverse shaft is arranged at the top-end position between the two supporting columns; a box body is arranged on the bottom plate between the two supporting columns; the output end of a second motor drives a drive gear torotate; the drive gear drives a transmission gear to rotate through a chain; the transmission gear drives a lead screw to rotate; the lead screw is in threaded connection to a nut base, so that a movable block moves along the lead screw, and therefore, longitudinal movement of a welding head is realized; and finally, a hydraulic cylinder controls a piston pushing rod to lift, so that movement, ina vertical direction, of the welding head is realized, and the welding head is in contact with a welding point; and the output end of a third motor drives a rotary shaft to rotate, so that a pipe clamp rotates, and therefore, integral welding work of the pipe is accomplished, manual welding is not needed, manual errors are avoided, and welding precision is improved.

Description

technical field [0001] The invention relates to the field of pipe material processing equipment, in particular to a welding device in pipe frame processing and assembly. Background technique [0002] The welding process is related to the welding method and other factors. The operation needs to be determined according to the material, grade, chemical composition of the workpiece to be welded, the structure type of the weldment, and the welding performance requirements. First, the welding method must be determined, such as manual arc welding, submerged arc welding, There are many types of welding methods, such as argon tungsten arc welding, gas metal arc welding, etc., which can only be selected according to specific conditions. After the welding method is determined, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode type (or grade), diameter, current, voltage, type o...

Problems solved by technology

[0004] The purpose of the present invention is to provide a welding device in pipe frame processing and assembly to solve the problem that in traditional welding methods, manual spot welding is often used for pipe assembly welding, especially multi-point welding, and the production efficiency is low. Moreover, errors are prone to occur during the manual welding process, resulting in flat welding surfaces and affecting the overall quality.
