Joint-type arc welding robot

Abstract

The invention provides a joint-type arc welding robot. A single chip microcomputer open-loop control technology is adopted for control and cooperates with an arc welding power supply, and variable-station automatic welding and automatic pipeline weld joint welding are achieved. The joint-type arc welding robot consists of a welding tool, joint-type arms, an automatic feeding hopper, a walking mechanism, a robot controller and a control power supply. Mutual matching and coordinated exercises of the welding tool, the joint-type arms, the automatic feeding hopper, the walking mechanism, the robot controller and the control power supply are controlled by welding control software fixed in the robot controller to perform automatic welding.

Description

technical field [0001] The invention relates to a mechatronics product, specifically, an automatic welding equipment for arc welding. Background technique [0002] At present, the equipment for automatic welding of pipe girth welds mainly includes the "all-position automatic welding machine" described in "Welding Handbook Volume One Welding Methods and Equipment" and the article "Application of Microcomputer in Welding" "Fixed pipeline automatic TIG welding machine". Its structure is composed of welding head, walking circular guide rail and control system. The control of the position of the welding torch is realized by the position signal of the welding torch, the logic control template, the rotary template of the welding torch, the wire feeding control template, the arc voltage control template, the magnetic control arc swing template, the mechanical arc swing template, etc. The control system includes a microcomputer and a control cabinet. The microcomputer is composed o...

Problems solved by technology

[0009] 1. It is not convenient to carry automatic welding equipment, and frequently move automatic welding equipment at the welding production site;

[0010] 2. It is impossible or inconvenient to fill argon gas, and it is not convenient to carry argon gas cylinder;

[0011] 3. New purchase of argon gas and round-trip transportation costs increase the cost of welding production;

[0012] 4. The welding production efficiency is low, prolonging the construction period of the pipeline system installation project

Using manual arc welding, not only the welding production conditions are poor, but the labor intensity of the workers is high, and the welding quality fluctuates greatly, which is easily affected by the workers' technical conditions and psychological emotions.
