Title: CONTOUR FOLLOWING TOOL AND METHOD
Abstract:
A contour following tool (14) for engaging the surface (46) of a workpiece (13) is disclosed. The tool has axially shiftable pins (32) that are biased toward a position in which they are fully extended from a housing. As the contoured surface (46) of the workpiece (13) is accommodated by allowing the pins (32) to shit back from their fully extended position against the biasing force. The pins may be biased by a fluid under pressure or by springs (62). The tool may be used with a wiping cloth (48) or end caps (70) that may apply a cleaning fluid that is applied either externally or internally through the tool through a bore (80) formed in one or more of the pins. An alternative embodiment is disclosed for gauging the contour of a surface. Another alternative embodiment is disclosed for an assembly tool (190). A clamping block (150) utilizing the invention is also disclosed. A method of cleaning a contoured workpiece is also disclosed.
