Rail type all-position welding robot for box-type steel structures

Abstract

The invention relates to a rail type all-position welding robot for box-type steel structures. The rail type all-position welding robot comprises a rail, a mounting mechanism is arranged on the left of the rail, a slider is slidably connected on the rail, a servo motor is arranged on the lower portion of the slider, a control box is arranged on the upper portion of the slider, a digital control system is arranged in the control box, an actuating mechanism is arranged on the left of the control box, a CCD (charge coupled device) and a laser generator are arranged on the actuating mechanism, a welding gun fixture is arranged at the left end of the actuating mechanism, and a welding gun is arranged on the welding gun fixture. The rail type all-position welding robot has the advantages that symmetric welding is realized, and welding stress is reduced; the rail type all-position welding robot adapts to influences of welding gun angles on welding process stability during welding of different positions, and weld penetration and forming quality are guaranteed; and welding parameter stability is guaranteed, and further, welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a box-shaped steel structure track-type all-position welding robot. Background technique [0002] The box-shaped steel structure has many advantages such as light weight, good plasticity and toughness, isotropy, simple manufacture, short construction and installation period, good sealing and heat resistance, etc. application is becoming more and more widespread. With the continuous development of the manufacturing industry, more and more welding robot systems have been put into use, and the development level of welding automation has also been greatly improved, especially in the fields of automobile production and construction machinery. On-site welding is mainly based on traditional manual welding, so the stability of welding quality is difficult to meet the manufacturing requirements, and in the field of steel structure installation involving offshore oil engineering equipment,...

Problems solved by technology

With the continuous development of the manufacturing industry, more and more welding robot systems have been put into use, and the development level of welding automation has also been greatly improved, especially in the fields of automobile production and construction machinery. On-site welding is mainly based on traditional manual welding, so the stability of welding quality is difficult to meet the manufacturing requirements, and in the field of steel structure installation involving offshore oil engineering equipment, steel structure houses, steel structure bridges When welding, high-altitude operations are often required, and the welding conditions are harsh, which even threatens the lives of welders

At the same time, the welding defects produced by manual welding have seriously affected the service life of some steel structure buildings, and buried hidden dangers for the occurrence of some accidents.

[0003] The main disadvantages of traditional manual welding are: two welders are required to carry out symmetrical welding, and the welding voltage and current, welding speed and number of welding layers of the two welders should be consistent during welding, which requires high coordination of welding workers; and On-site welding conditions are harsh, and there are many factors affecting welding quality, so manual welding is difficult to guarantee welding quality
