Power-actuated vise apparatus for use with e.g. robot, has force coupler unit taking torque force from torque transmitting member for resulting in generation of angular force and linear force

摘要

The apparatus has a carrier placed to support a jaw (23), where the carrier is driven by angular force to move the jaw along a guideway between engaged and disengaged positions in an initial course. The carrier is pressed by linear force along the guideway in a subsequent course to supply the jaw into a tightened engagement with a workpiece from a preliminary engagement to tighten the workpiece against another jaw (22). A servo control mechanism is arranged to deliver torque force. A torque transmitting member (50) is placed to be driven by the mechanism to transmit the torque force. A force coupler unit couples the torque transmitting member to the carrier, and takes the torque force from the torque transmitting member for resulting in generation of the angular force and the linear force.
