UNILOCK Modular Workholding System Vol. 3

OVERVIEW

HOW IT WORKS UNILOCK utilizes spring pressure to drive multiple clamping pins against a tapered clamping knob. Air pressure is used to compress the springs to back the clamping pins off of the clamping knob. This clamping process is achieved by bleeding the air pressure out of the chuck. To facilitate palletization, the clamping knob is attached to a base plate, fixture or directly to a workpiece. The result is quick and repeatable clamping. A hand locking version (no air required) is also available.

FEATURES • Clamping mechanism: heavy-duty die springs • Chuck opening: air pressure to compress springs • Clamping stability: low profile with matching taper wedges • Positional accuracy: adaptable to workpiece conformation • Unlocking air pressure: 75 PSI • Turbo assist clamping

SINGLE CHUCK APPLICATIONS The UNILOCK clamping knob mates with the central taper in the chuck to establish the centerline location (XY reference in a cartesian coordinate system). A timing pin or key locates in a notch or bushing to orient the coordinate system relative to XY and to restrict rotation. The Z reference in this same coordinate system is established by the bottom of the fixture or workpiece contacting the top ground surfaces of the chuck. These same mating surfaces (bottom of the fixture and top of the chuck) will control axial alignment. The clamping knob can be used for locking down a workpiece without influencing location if external features are used for positioning.
