A gripper includes a body and an actuator coupled to the body. The gripper further includes a first hub rotatably mounted to the body where the first hub is drivingly engaged with the actuator. A second hub is selectively drivingly engaged with the actuator. The second hub rotates in a direction opposite to the first hub. A first arm is coupled to the first hub and a second arm is coupled to the second hub. The first and second arms are articulable from open position to closed positions.
A powered clamp includes a pair of moveable members which engage one another to maintain, at least temporarily, a locking position of an arm when actuating fluid pressures have been decreased or lost. In another aspect of the present invention, the apparatus is simplified by engaging a slide rod with a rotatable hub. Furthermore, the overall packaging envelope required by the clamp is reduced by aligning the transverse axis of the rotatable hub with a longitudinal axis of an actuator.
A gripper includes a body, an actuator movably supported by the body and a first hub rotatably supported by the body where the first hub rotates about a transverse axis. The gripper also includes a drive arm having a camming surface. The drive arm is coupled to the first hub so as to be rotatable about the transverse axis. A member drivingly interconnects the camming surface and the actuator such that an arm coupled to the first hub operably moves in response to the actuator.
