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.

Abstract: A steady rest having cams for adjusting both vertical and the horizontal position of the centerline of a cylindrical workpiece.

Abstract: This invention is related to a steady rest, which employs a pair of parallel, sliding, linear moving clamping bars for moving wear pads or rollers toward a workpiece.

Abstract: A centering and supporting apparatus is disclosed for use as a true centering steady rest for rotatably supporting a cylindrical workpiece during a machining or grinding operation. The apparatus has an internal centerline adjustment mechanism for adjusting the steady rest so as to support the workpiece at its dynamic working centerline. At least one, or a pair of support arms are slidably mounted on an operator body in a housing. Said one or pair of support arms each carries a side workpiece contact member, and the operator body carries a center workpiece contact member, and each workpiece contact member is engagable with the perimeter of the workpiece. The operator body is moved by a stroking means to urge the center workpiece to support a workpiece.

Abstract: An automatic true centering steady rest apparatus for a rotating cylindrical workpiece during a machining or grinding operation on the workpiece. The apparatus has an integrally mounted gaging device, for continuously gaging the diameter of a workpiece during a machining or grinding operation. A pair of gripper arms are slidably mounted on an operator body in a housing. Each gripper arm and the operator body carries a workpiece contact member engageable with the perimeter of the workpiece. The gripper arms are urged to grip a workpiece by the action of a pair of rollers and two sets of fixed guide pins which are operatively engageable with camming contours contained on opposing inner surfaces of the apparatus housing. The improved efficiency of the apparatus, as a result of the roller and guide pin action allows for placing the gaging device remotely from the workpiece, without any loss in the precision of its measurement.

Abstract: An automatic centering and gripping apparatus which includes a housing in which is slidably mounted a longitudinally movable operator body. A pair of gripper arms are slidably mounted on the operator body. Each gripper arm carries a gripper member engageable with a workpiece. The gripper members are moved longitudinally and laterally into gripping engagement with a workpiece when the operator body is moved in one longitudinal direction, and they are correspondingly disengaged from the workpiece when the operator body is moved in the other longitudinal direction.

Abstract: A gripping apparatus which includes a housing in which is slidably mounted a longitudinally movable gripper operator. A pair of gripper arms are rollably mounted on the gripper operator. Each gripper arm carries a gripper jaw engageable with a workpiece. The gripper jaws are moved along straight line travel paths into gripping engagement with a workpiece when the gripper operator is moved in one longitudinal direction, and they are disengaged correspondingly from the workpiece when the gripper operator is moved in the other longitudinal direction.
