Abstract: A fixture assembly may include a housing, a clamp assembly, and a drive mechanism. The clamp assembly may be movably mounted to the housing and may include a first clamp member and a second clamp member. The first and second clamp members may be linearly movable relative to the housing toward and away from each other. The drive mechanism may be coupled to the clamp assembly and the housing and may drive the clamp assembly relative to the housing such that the first clamp member moves linearly toward the second clamp member at a first speed in a first direction and the second clamp member moves linearly toward the first clamp member at a second speed in a second direction that is opposite the first direction. The first speed may be different than the second speed.

Abstract: A fixture mechanism may include first and second outer plates, a central plate and first and second guide members. The second outer plate includes a first face facing the first outer plate. The second outer plate may include first and second guide channels and a guide-member recess. The guide channels may be fixed relative to the first outer plate. The central plate is movably disposed between the first and second outer plates. The central plate may slidably engage first and second gripping arms that are movable relative to the outer plates between a clamped position and a retracted position. The guide members may be received in the guide-member recess and may be movable relative to the second outer plate and relative to each other within the guide-member recess to adjust a position at which the workpiece will be clamped when the gripping arms are in the clamped position.

Abstract: An adjustable fixture mechanism may include a first housing, an adjustment control plate, an adjustment member, and an adjustment control member. The first housing includes an adjustment aperture. The adjustment control plate is supported by the first housing and include an adjustment control aperture. The adjustment member may be disposed within the adjustment aperture and include a proximal end, a distal end and a first central axis extending through the proximal and distal ends. The adjustment control member may be disposed within the adjustment control aperture and include a proximal end and a distal end. The adjustment control member may be rotatable within the adjustment control aperture about a second central axis that is offset from the first central axis. The distal end of the adjustment control member may include a ramped surface extending about the second central axis and in contact with the proximal end of the adjustment member.
