ABSTRACT:
A workpiece holding system includes a connector for mounting a workpiece-holding pallet or upper plate to a workstation with the high degree of accuracy that is necessary for workpiece machining operations. The upper plate connects to the workstation via a pair oppositely directed, extendable/retractable connectors aligned along an axis of connection, with a total of four connectors and two spaced axes of connection, though three such connectors may also be used. At least one of the connectors includes a pin, an actuating knob and a wrap spring, thereby to permit extension and retraction along the respective axis by rotation of the actuating knob. The wrap spring interconnects the actuating knob to the pin in a slippable manner. The wrap spring acts as a torque limiting device during rotation of the knob to extend the pin into engagement with the upper plate, and it acts as a clutch during rotation of the knob to retract the pin from engagement with the pallet. The wrap spring provides advantage in automating work-holding operations. Additional versatility in work-holding operations may be achieved by mounting a plurality of the connectors to a like number of pillars which are selectively positionable to a work table, thereby to hold a workpiece in three dimensional space.
