Pipeline intersecting line welding system

Abstract

The invention provides a pipeline intersecting line welding system, and belongs to the technical field of pipeline welding. The pipeline intersecting line welding system is characterized by comprisinga parallel robot (A1), an electric sliding rail assembly (B1) and a door-type bracket, the electric sliding rail assembly (B1) is arranged on the upper part of the door-type bracket, the upper part of the parallel robot (A1) is installed on the door-type bracket through the electric sliding rail assembly (B1), and a welding gun (5) is installed at the lower part output end of the parallel robot (A1); the parallel robot (A1) comprises a fixed platform (1), motion branched chains (2), center telescopic branched chains (3) and a motion working table (4), and the multiple groups of motion branched chains (2) and the center telescopic branched chains (3) are arranged between the fixed platform (1) and the motion working table (4). According to the pipeline intersecting line welding system, themotion branched chains and the center telescopic branched chains are adopted, and the motion effect of driving the welding gun to integrally move three times and rotate once is achieved. The workingspace of a mechanism is increased, and meanwhile, the problems of self locking and redundant constraint caused by asymmetric branched chains existing in a parallel mechanism are solved.

Description

technical field [0001] A pipeline intersecting line welding system belongs to the technical field of pipeline welding. Background technique [0002] The welding process of mechanical products is currently the most commonly used in two ways: manual welding and robotic welding. During the welding process, on the one hand, the heat and light released are dazzling, and on the other hand, the harmful substances released will endanger human health. Although manual welding is flexible in operation and widely applicable, the uniformity of welding quality cannot be guaranteed, and the welding efficiency is extremely low, the working environment is poor, the requirements for workers' welding skills are extremely high, and the labor intensity is high, especially not suitable for welding aluminum and titanium. And other active metals, and low melting point metals and insoluble metals. However, manipulator welding is expensive and requires a large one-time investment. Because it involv...
