CUTTING AND WELDING ROBOT DEVICE

摘要

PURPOSE:To prevent the occurrence of the defective cutting by abutting an interval maintenance member provided to the torch tip on an object and pushing in a torch by a prescribed stroke against an unidirectional energization means to perform the cutting and maintaining an interval between the torch tip and the object to a prescribed value. CONSTITUTION:The interval maintenance member 8 is formed cylindrically and its tip side is formed in a tapered shape and an opening part 8a is formed on its end face part. Said interval maintenance member 8 is abutted on the object 10 of the cutting work and the size of the interval maintenance member 8 is set so that a gap G between the torch 2 tip and the object 10 is formed to the prescribed value. Then, the torch 2 is supported slidably and energized on the object 10 side by the unidirectional energization means 7 and the interval maintenance member 8 is abutted on the object 10. The cutting is performed in a state with the torch 2 pushed-in by the prescribed stroke against the unidirectional energization means 7. In this way, the gap between the torch tip and the object is accurately maintained to the prescribed value to prevent the occurrence of the defective cutting.
