Robot-based automatic welding apparatus especially for steel grating plate and working method thereof

Abstract

Disclosed in the invention is a robot-based automatic welding apparatus especially for a steel grating plate. The robot-based automatic welding apparatus comprises a fixed seat, a horizontal shaft, a first joint shaft, a second joint shaft, a welding gun, and a control device. The fixed seat is fixed on the ground by foundation bolts; the horizontal shaft is fixed on the fixed seat by a positioning pin; and the horizontal shaft, the first joint shaft, the second joint shaft, and the welding gun are connected with the control unit by a circuit. According to the automatic welding apparatus, a position sensor is installed on an arm of a robot and is controlled by an automatic control system to localize a welding point accurately and thus cooperation with the welding gun is realized, thereby substantially improving the welding accuracy of the welding device, effectively guaranteeing the stability and consistency of the welding quality, effectively avoiding insufficient welding and solder skips and thus realizing precise welding. In addition, the invention also relates to a working method of the automatic welding apparatus.

Description

technical field

[0001] The invention relates to a welding device, in particular to a special robot automatic welding device for welding steel grid plates and a working method thereof. Background technique

[0002] Steel grating carbon dioxide gas is mainly used for edge sealing of steel grating. Most welding companies still use manual welding for welding. The workload is very heavy. At the same time, due to the large number of people in the welding process Most of them are welded with the naked eye, and the quality of the welding is not stable enough. Due to the poor controllability of people, it is difficult to keep the quality of the welding consistent. Because the welding points are relatively dense, the technical requirements for welding workers are high. The matching of position and parameters is not easy to maintain the best. During the welding process, problems of false welding and missing welding often occur, and the gas generated during the welding process will ...
