ABSTRACT:
A gripper mechanism having at least one pair of opposing and co-acting gripper fingers that can be actuated to move from a non-gripping to a gripping position and vice versa upon application of a control signal to the gripper and the subsequent motion of the gripper actuator being applied to move the gripper fingers. The gripper provides an assembly to adjust the spacing between each of the pairs of opposing and co-acting gripper fingers, thus providing an adjustability feature to the gripper permitting thereby the ability of the gripper to grip parts of different sizes and of irregular geometries. One or more grippers as previously described may be incorporated with a material-handling apparatus having controls, power sources, platforms and other features appropriate to handle, orient, operate on, move and otherwise process parts in any fashion, where the gripper provides the apparatus with the adjustability to grip, hold, handle, orient and move parts of different sizes.
