Technical Indicators Of Welding Workstation

The dual-robot welding workstation consists of a dual-axis positioner system, TIG welding power supply, 3 welding robots, 1 handling robot, safety protection system, video monitoring system and accessories such as gas cylinders, which can realize spot welding or TIG welding respectively. The opening stroke of the spot welding clamp is not less than 300mm, the motor pressure is not less than 3500N, the rated capacity is 85KVA, and the frequency is 1800Hz. The fixture is strong enough, the positioning is accurate, the operation is convenient, the structure is reasonable, and the reliability is high. The hardness of the positioning surface material reaches HRC40~45; Technical requirements for welding robots: (1) The welding robot adopts ABB, which can ensure the motion accuracy and repeated positioning accuracy, and selects a dual-axis positioner system that matches the robot to achieve linkage; (2) The robot body is a six-axis rotary joint design; (3) The effective working diameter of the robot arm (excluding the welding gun) is ≥2655mm or 1400mm (arc welding), load: not less than 160kg or 5kg (handling) and 5kg (arc welding); (4) *Machine Point-to-point repeat positioning accuracy: 0～±0.05mm; (5) * The robot can realize the integrated control of welding power supply, wire feeding system and turntable; the turntable can be controlled by digital interface to realize linkage with the robot. Its main technical indicators are as follows: (1) Maximum load and drive weight is not less than 300kg; (2) Repeat positioning accuracy is not less than ±0.2mm; (3) Maximum rotation speed: 55°/s; (4) Maximum tilting speed: 50°/s; (5) Rotation angle: ±1.
