Abstract
A clamp includes a body, a lead pin moveable relative to the body and an actuator supported by the body. The actuator is axially moveable between an extended position and a retracted position. The actuator includes a camshaft drivingly coupled to the lead pin. Axial movement of the camshaft causes the lead pin to rotate between a first positioned aligned with a first longitudinal axis and a second position aligned with a second longitudinal axis laterally offset from the first longitudinal axis.
Claims28
A clamp comprising:
- a body;
- a lead pin axially and rotatably moveable relative to the body;
- and
- an actuator supported by the body, the actuator being axially moveable between an extended position and a retracted position as well as including a camshaft drivingly coupled to the lead pin, wherein axial movement of the camshaft causes the lead pin to rotate between a first positioned aligned with a first longitudinal axis and a second position aligned with a second longitudinal axis laterally offset from the first longitudinal axis.
A clamp comprising:
- a body;
- an actuator moveably supported by the body, the actuator including a pair of rollers, each roller being positioned within one of two grooves formed on an axially and rotatably moveable camshaft, each groove including a plurality of detents;
- and
- a clamping member drivingly coupled to the actuator, wherein the clamping member axially translates and rotates between an extended position and retracted position in response to movement of the actuator, the rollers being positionable in engagement with the detents to restrict movement of the clamping member in the absence of force being provided by the actuator.
A method of operating a clamp having a body with an actuator moveably supported by the body, the actuator having a camshaft in driving engagement with rollers, the actuator being drivingly coupled to a pin having a body and a head, the method comprising:
- linearly translating the actuator;
- engaging the rollers with slots formed in the camshaft to rotate the camshaft as it translates;
- and
- rotating the head of the pin along an axis offset from the longitudinal axis of the pin to cause the head of the pin to partially overhang the pin body during clamping.
