The welding robot is an industrial robot engaged in welding (including cutting and spraying). The International Organization for Standardization (ISO) industrial robot is defined as a standard welding robot, which is a multi-purpose, repeatable, programmable, automatic control manipulator with three or more programmable axes for industrial automation. To accommodate different uses, the mechanical interface of the last shaft of the robot, usually a connecting flange, can be attached to a different tool or end effector. the welding robot is a welding tongs or a welding (cutting) gun at the end shaft flange of an industrial robot, So that it can be welded, cut, or thermally sprayed.
With the development of electronic technology, computer technology, numerical control and robot technology, automatic welding robot has been used in production since 1960's, its technology has become more and more mature, mainly has the following advantages:
1) stabilizing and improving the welding quality, which can reflect the welding quality in the form of numerical value;
2) improve labor productivity;
3) The labor intensity of the workers can be improved, and work can be carried out under the harmful environment;
4) reduce the requirement of workers' operating skills;
5) shorten the preparation period of product transformation and reduce the corresponding equipment investment.
Therefore, in a variety of industries have been widely used.
The welding robot is also an important part of the robot family. In the rapid development of the industrial robot, the robot is applied to all walks of life and has a very good performance, and the machine-changing is no longer a dream. At the same time, the rapid development of the robot industry can not be separated from the support of the surrounding industry, and we innovate the original cross roller bearing, which is more suitable for the use of the robot and the welding robot, and has good performance.
