A welding robot arm for industrial parts and its working method

Abstract

The invention discloses an industrial part welding mechanical arm and a working manner thereof. The industrial part welding mechanical arm comprises a part conveying belt and a welding gun. A mechanical arm base is mounted at the center position of the part conveying belt. One end of a first extending arm is mounted above the mechanical arm base. One end of a second extending arm is mounted at theother end of the first extending arm. The welding gun is mounted at the other end of the second extending arm. The first extending arm and the mechanical arm base are fixedly connected. The first extending arm and the second extending arm are connected through a gear structure. The second extending arm and the welding gun are connected through a rotary motor. According to the industrial part welding mechanical arm, through the matched motion function to the mechanical arm and a welding conveying belt, horizontal rotation of the mechanical arm and the angular speed of the annular part conveying belt are the same, part conveying does not need to be stopped in the welding function, the angle difference between welding of the rotary motor and rotating of the mechanical arm base around the part conveying belt is reduced through PLC control, the part welding speed is increased, and the quality and efficiency of part welding are improved.

Description

technical field [0001] The invention relates to the technical field of industrial manipulators, in particular to an industrial parts welding manipulator and its working method. Background technique [0002] Manipulators have become very popular as a substitute for manual labor in industrial applications. Manipulators can move in the entire space by adjusting the degree of freedom. However, in some industrial production occasions, it is not necessary to use such complex and expensive manipulators. Through The control of the program and the effective operation of the motor can achieve the purpose of work. [0003] At present, welding manipulators have been widely used in the field of automobile manufacturing. This kind of welding is mainly spot welding. Usually, multi-point welding is performed on irregular welding bodies. In the welding of industrial parts, the welding position is relatively fixed, and only four free A manipulator with a high degree of precision can complete...

[0003] At present, welding manipulators have been widely used in the field of automobile manufacturing. This kind of welding is mainly spot welding. Usually, multi-point welding is performed on irregular welding bodies. In the welding of industrial parts, the welding position is relatively fixed, and only four free The welding action can be completed by a high-speed manipulator. The welding of cylindrical parts is more complicated. Usually, only a six-axis manipulator can complete the welding action of the center of the circle, or multiple welding manipulators cooperate to complete it. In the existing technology, welding usually needs to be stopped. Conveyor belt transmission and fixed-point welding, this method can no longer meet the production needs of batch industrial parts
