Full-automatic welding robot

Abstract

The invention belongs to the technical field of robots and provides a full-automatic welding robot. The full-automatic welding robot comprises a track, and a mounting mechanism is arranged on the left side of the track. A sliding block is sliably connected to the track. A servo motor is arranged on the lower portion of the sliding block. A control box is arranged on the upper portion of the sliding block. A digital control system is arranged in the control box. An executing mechanism is arranged on the left side of the control box and provided with a charge coupled device (CCD). A welding gun clamp is arranged at the left end of the executing mechanism. According to the full-automatic welding robot, two sets of welding robot moving mechanisms carry out welding at the opposite positions of the box-type steel structure section in the same rotation direction, symmetry welding is achieved, and welding stress is reduced. The technical requirements for welding of different positions in a V-shaped groove and a Y-shaped groove are met through four-degree-of-freedom movement of the executing mechanism, so that the penetration and molding quality are ensured, the full-automatic welding robot also adapts to the influence of the angle of a welding gun on stability of the welding process during welding in different positions, and the weld penetration and molding quality are ensured.

Problems solved by technology

[0002] 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. However, for box-shaped steel structures The welding at the installation site is still mainly based on traditional manual welding, so the stability of the welding quality is difficult to meet the manufacturing requirements, and in the steel structure installation site involving offshore oil engineering equipment, steel structure houses, steel structure bridges and other fields When welding, it is often necessary to carry out high-altitude operations, and the welding conditions are harsh, which even threatens the safety of welding workers

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

In addition, due to the harsh working environment during field construction, this traditional operation method is labor-intensive and technically difficult, which has caused problems such as difficulties in welder training and serious loss

The automatic welding equipment used in China needs the welder to adjust the centering weld in real time during welding, and it is difficult to weld the girth weld of the spherical tank except the equator. Therefore, there is still an urgent need to solve the problem of adaptive control of all-position automatic tracking of welds of different forms and parameters
