<p>According to the invention, the two-axes-compensation and anticollision device comprises a structure (11, 12, 14, 14', 15, 15.1, 16) for connection between a horizontal plate (Bl) fixed to a manipulator arm (B) and a horizontal, plate (B2) for attachment of the operating tool (P) having a variable-geometry articulated parallelogram configuration, under the action of forces a component of which is directed along a cartesian axis in the horizontal plane (X, Y), and controlled translational sliding mobility, under the action of forces a component of which is directed according to the other cartesian axis in the horizontal plane (Y, X), so as to exceed, by means of variation of geometrical configuration and/or by means of controlled mobility, a physical barrier with respect to which said tool operatively interferes, if the order of the interference between said parts falls within a range of predetermined dimensional tolerances with respect to the cartesian axes (X, Y) in the horizontal plane. Spring means (15.2, 17, 17.1, 17.2, 18, 19; 16, 16.1, 16.2, 21, 22) for compensation of said variation of geometrical configuration and/or of said controlled mobility, after said physical barrier has been exceeded, automatically restore the initial geometry and arrangement of said structure.</p> |
