This project is mainly used for automated welding of frame structural components. The incoming material is the assembly parts that are manually assembled and assembled, which are loaded and welded in two steps. The material is manually lifted and loaded by a crane, and the tooling is automatically clamped.

This robot welding workstation adopts a single workstation operation mode. Each workstation is composed of one welding robot, one three-axis robot inverted gantry, one head and tail frame dual drive displacement machine with tail frame automatic movement, welding system, point laser positioning system, and smoke and dust treatment system. The total number of axes is 11 and can be linked together.

The displacement machine uses a two axis H-type displacement machine. The H-series two axis displacement machine is an intelligent standardized product of Aoguan. In order to adapt to the welding of various welds in the * * position of the workpiece to the maximum range, this two axis H-type displacement machine is specially equipped. The H-type displacement machine has the widest adaptability and angle range, and can meet the welding of most welds in the * * position of the arm frame. The displacement machine and the head and tail frames are both driven by servo motors from the robot manufacturer, directly controlled by the robot controller, and used as external axes for linkage with the robot. The tailstock is adjustable and compatible with a certain range of workpiece lengths.

This welding uses multi-layer and multi pass functions. Multi layer and multi pass welding has a special effect on improving welding performance. It not only improves the performance of welded joints due to low welding line energy, but also reheats the previous weld and its heat affected zone, causing phase transformation and recrystallization of the microstructure and properties in the heating zone, forming fine equiaxed crystals, and improving plasticity and toughness.
