US Patent 12109633 Integrated toolless clamp

A toolless clamp, toolless clamping system, and methods of use comprising a torque-limited rotation system operatively coupled to a ball-lock pin. The rotational system may be manually tightened without use of a tool to advance a spring-actuated spindle of the ball-lock system to engage lock balls. The clamp shank has a D-shaped cross-section corresponding to a D-shaped bushing in the fixture to inhibit rotational movement of the clamp during tightening. The clamp and D-shaped bushing may be used with a receiver bushing in the subplate to receive and retain the lock balls when deployed from the ball-lock pin.
