ROBOT GRIPPER FOR FIXTURING A THREE-DIMENSIONAL OBJECT

摘要

A robotic gripper for fixturing and manipulating a sheet of substantially rigid material e.g. a sheet metal part has three fingers with circumferential grooves thereon. The sheet metal part has at least one opening of a size suited to accommodate one of the fingers. The other fingers can engage the edges of other openings in the sheet metal part or the outside edge of the part. The fingers can be moved away from each other or towards each other respectively depending on the positioning of the fingers, whereby the sheet metal part is fixtured by means of the grooves of the fingers.
