A clamping assembly is provided. The clamping assembly includes a base member having a base portion and an extension portion. The clamping assembly further includes a piston that is adapted to move first and second cam fingers toward the base portion to induce first and second pins, respectively, to move first and second wedge members, respectively, in first and second directions, respectively, on the extension portion to lift a wedge coupling member relative to the extension portion. The clamping assembly further includes a shaft coupled to the wedge coupling member that is further coupled to a clamping arm. |

1. A clamping assembly, comprising:
a base member having a base portion and an extension portion extending from the base portion, the base member having an aperture extending through both the base portion and the extension portion along a longitudinal axis, the extension portion having first, second, third, and fourth side surfaces and an end surface, the end surface defining first and second guiding grooves that extend substantially parallel to one another and into the extension portion, the extension portion further having a first side groove extending from the first side surface into the extension portion, the extension portion further having a second side groove extending from the second side surface into the extension portion; a first wedge member being slidably disposed in the first guiding groove on the end surface of the extension portion; a first pin coupled to the first wedge member that extends outwardly from a side surface of the first wedge member in a direction substantially perpendicular to the first side surface of the extension portion; a second wedge member being slidably disposed in the second guiding groove on the end surface of the extension portion; a second pin coupled to the second wedge member that extends outwardly from a side surface of the second wedge member in a direction substantially perpendicular to the second side surface of the extension portion; a wedge coupling member disposed on the first wedge member and the second wedge member, the wedge coupling member slidably engaging the first and second wedge members such that the wedge coupling member moves along the longitudinal axis away from the end surface when the first wedge member moves in the first groove in a first direction, and the second wedge member moves in the second groove in a second direction, the second direction being in an opposite direction relative to the first direction; a first cam finger having a first elongated aperture extending therethrough, the first pin being disposed in the first elongated aperture; a third pin coupled to the first cam finger proximate to an end of the first cam finger, the third pin extending into the first side groove of the extension portion such that the third pin is slidably received in the first side groove; a second cam finger having a second elongated aperture extending therethrough, the second pin being disposed in the second elongated aperture; a fourth pin coupled to the second cam finger proximate to an end of the second cam finger, the fourth pin extending into the second side groove of the extension portion such that the fourth pin is slidably received in the second side groove; a piston pivotally coupled to another end of the first cam finger and another end of the second cam finger, the piston being adapted to move the first and second cam fingers toward the base portion to induce the first and second pins, respectively, to move the first and second wedge members, respectively, in the first and second directions, respectively; and a shaft coupled to the wedge coupling member and extending through the aperture of the base member, the shaft further coupled to a clamping arm. |
