MACHINE FOR LASER WORKING OF TUBES AND PROFILED SECTIONS WITH A SCANNING SYSTEM FOR SCANNING THE TUBE OR PROFILED SECTION TO BE WORKED

摘要

The machine comprises: a working head (12) with a focussing device (18) arranged to focus a laser beam on the surface of the tube or profiled section (T) to be worked, a carriage (26) on which the working head (12) is mounted and a scanning system (20) arranged to scan at least a portion of the outline of the cross-section of the tube or profiled section (T). The carriage (26) is able to translate with respect to the tube or profiled section (T) both in a longitudinal direction (x) coinciding with the longitudinal axis of the tube or profiled section (T) and in a transverse direction (y). The scanning system (20) comprises at least one laser scanning module (20) comprising a laser emitter (22) arranged to emit a light blade (L) with which to illuminate a portion of the tube or profiled section (T) and a camera (24) arranged to acquire an image of the portion of tube or profiled section (T) illuminated by the light blade (L). The working head (12) and the at least one laser scanning module (20) are mounted on the carriage (26) so as to be drivingly connected for translation with said carriage (26) both in the longitudinal direction (x) and in the transverse direction (y).
