Workholding apparatus

摘要

A device for holding a workpiece, the device comprising a base, a first jaw member, a movable jaw member, and features which allow the movable jaw member to be moved in large increments relative to the first jaw member in addition to features which allow the movable jaw member to be moved in smaller increments. The device can include a drive member operably engaged with the base and the movable jaw member such that the operation of the drive member can move the movable jaw member in small increments. The movable jaw member can include a connection member, or claw, which can operatively engage the movable jaw member with the drive member. The connection member can be moved between first and second positions to disengage the movable jaw member from the drive member such that the movable jaw member can be slid relative to the first jaw member in large increments.

主权项

1. A workholding apparatus comprising:
a base; a longitudinal member comprising an array of engagement portions; a drive member operably engaged with said longitudinal member; a first jaw member; a second jaw member slidably engaged with and supported by said base, said second jaw member comprising a link movable between a disengaged position in which said link is operatively disengaged from said longitudinal member and an engaged position in which said link is engaged with said longitudinal member; a selectively operable motor, wherein said motor is configured to move said drive member and said second jaw member relative to said first jaw member when said link is engaged with said longitudinal member, and wherein said second jaw member is movable relative to said first jaw member and said drive member when said link is disengaged from said longitudinal member; and a socket, wherein said motor comprises a rotatable shaft, and wherein said socket rotatably couples said rotatable shaft to said drive member.
