Integrated toolless clamp

A toolless machine tooling clamp comprising:

• a hand-operable torque-limited rotation system operably coupled to a ball-lock pin assembly having a generally D-shaped cross-section and comprising an outer clutch handle element operably coupled to an inner clutch handle element disposed within said outer clutch handle element, said outer clutch handle element being generally in the configuration of a hollow cylinder having an outer surface and an opposing inner surface, said outer surface sized and shaped for gripping and rotation by a human hand, and said inner surface comprises a groove, said groove comprising a first side disposed in the configuration of a radial plane relative to a major axis of said outer clutch handle element and an opposing, second side having a sloped configuration;
• wherein said inner clutch handle element is generally in the configuration of a cylinder having an axial bore defining an inner surface and extending from a first end of said inner clutch handle element to a terminus within said inner clutch handle element;
• wherein said inner clutch handle element further comprises:
• an outer surface having a radius about the same as a radius of said inner surface of said outer clutch handle element and at least a portion of said inner surface of said inner clutch handle element is threaded;
• a radial bore extending from said outer surface of said inner clutch handle element to a terminus disposed within said inner clutch handle element, said radial bore disposed at a position on said outer surface corresponding to said groove such that when said outer clutch handle element is rotated around said inner clutch handle element, said groove passes over said radial bore;
• a clutch plunger generally in the configuration of a hollow cylinder having a first closed end and an opposing open end, said clutch plunger slidingly disposed within said radial bore with said first open end proximal said terminus;
• and
• a clutch spring disposed within said clutch plunger, said clutch spring having a first end and an opposing second end, said first end extending through said open end of said clutch plunger and braced against said terminus, and said second end braced against an interior surface of said closed end of said clutch plunger, said clutch spring applying radially outward force to said clutch plunger to tend to cause said clutch plunger to retreat radially outward.
