ABSTRACT:
The invention concerns a parallel pneumatic gripper which includes a gripper body (11) forming a chamber (15), an alternate pneumatic piston (12) movable in the chamber, and two jaws (13, 14) controlled by the piston and movable in opposite directions. A first jaw (13) is rigidly attached to the piston (12) to follow its movements, whereas the second jaw (14) is connected to the piston (12) by an oscillating transmission element or lever (22, 22′) comprising an intermediate larger dimensioned cross section portion (23, 30) having a transversal bore to house the oscillating central fulcrum and two terminal heads with rolling surfaces (25, 25′; 31, 31′) designed to couple with corresponding seats provided respectively on the bottom of a flaring shaped in one side of the piston (12) and in the second jaw (14).
