Abstract: A tool for precisely positioning a workpiece upon a related component part that includes a housing having reciprocally mounted therein a piston and an associated piston. Connected to and mounted for relative movement therewith is a nozzle which is arranged to attach to a workpiece when a negative pressure is imparted to the nozzle. Circumferentially spaced about the housing are at least two pairs of complementary fingers that are sequentially actuated to effect the sequential positioning of the workpiece held on the end of the nozzle along a first and second axis relative to the nozzle. The arrangement is such that the precise positioning of the workpiece on the end of the nozzle is effected in translating the workpiece from its pick-up position to its deposit position where the workpiece is precisely positioned upon its receiving component part.
