Abstract


In this paper, the current domestic Shipyard cubicle structure of the production process, low productivity, poor quality of welding, poor status of the production environment, as well as human factors, the production of high labor intensity, deformation, proposed the use of complex issues such as welding robots ideas, and made a gantry robot welding systems and robot welding system driving two kinds gondola general idea of ​​the reality through the two programs and the advantages and disadvantages compared to determine the choice of the latter as the main object of study. According to the cubicle structure robotic welding system with the requirements of the desired robot welding systems, welding power source, wire feed systems and other equipment for a reasonable choice to determine the welding system equipment required and described in detail. According to the construction site at the request of driving basket robot welding system was streamlined layout design, three layouts are compared and analyzed to determine the layout of the program selected and the basket under the program completed the manufacture and installation of equipment . In this paper, Kuka Sim Pro software to build traffic gondola robot system model, robotic welding system to carry out simulation studies to verify the reachability of the gun as well as the feasibility of robotic workstation. Kuka Sim Pro-based programming techniques used in the robot kinematics simulation system controls the welding robot, the robot welding draw the best path. And use the results of the simulation of the robot internal software settings to be modified to achieve the soft limit, to obtain a safe working environment. This paper studies the T-joint robot welding process, the welding parameters through research, based on optimization of the welding process requirements developed robot boxer welding, vertical fillet welding on weldment surface paint and clearance process parameters under different circumstances. Based on the structure of robot teaching cubicle verified cubicle inside the robot reachability, according to the ship welding process, developed a welding sequence. Completed a cubicle pieces welded structure simulation to verify the structure of the robot workstation used cubicle actual production feasibility. Using robotic welding process compared with the original manual welding, weld appearance, stable welding quality, increased productivity, with greater social and economic benefits.
