Abstract:
1. Manipulator at low inertia for laser cutting machines for flat sheet metals, comprising a longitudinal movement axis X and a transversal movement axis Y perpendicular to said longitudinal axis and parallel to the plane of the sheet metal, and a supporting equipment ( 15 ) for a laser cutting head ( 14 ) which is displeaceable along said axes, characterized in that said supporting equipment ( 15 ) comprises two sliding blocks ( 5 , 6 ) driven by respective independent actuators ( 7 , 8 ) to move along the axis Y at a variable mutual distance, and two rods ( 9 , 10 ) arranged as a V for the articulated connection of said sliding blocks ( 5 , 6 ) to said laser cutting head ( 14 ), a first rod ( 9 ) having a first end hinged on a first sliding block ( 5 ) so as to be rotatable around a first axis ( 11 ) perpendicular to the plane of the sheet metal and a second end integrally fixed to said head ( 14 ) and a second rod ( 10 ) having a first end hinged on a second sliding block ( 6 ) so as to be rotatable around a second axis ( 12 ) perpendicular to the plane of the sheet metal and a second end hinged on said second end of the first rod ( 9 ) so as to be rotatable around a third axis ( 13 ) perpendicular to the plane of the sheet metal.
