A gripping assembly for a robot includes a body and a pair of jaw supports supported for slidable movement on the body toward and away from each. Each jaw support has a pair of spaced apart apertures for receiving spaced apart securing posts of a jaw. Each jaw support includes a support body and a pair of locking slides. Each locking slide has a first end configured to engage a securing post when the securing post is disposed in a corresponding aperture. At least one actuator is configured to drive the locking slides away from each other to engage the securing posts. A jaw support actuator is configured to drive the jaw supports toward and away from each other.
A vise assembly includes a base and a pair of side walls extending from the base having guideways. A jaw is configured for guided movement by the guideways. A friction holding stop is secured to the jaw configured to selectively and frictionally engage a surface of the base and inhibit sliding movement of the jaw on the guideways. The friction holding stop includes a support secured to the jaw including a cavity opening toward the surface of the base. A member is disposed within the cavity and movable toward and away from the surface, the member having a portion engageable with the surface of the base. A spring is configured to urge the member toward the surface of the base. An actuator is coupled to the member and the support, the actuator configured to selectively move the member away from the surface against a spring force from the spring.
A vise assembly has a base and a pair of side walls extending from the base and providing guideways. A jaw is configured for guided movement by the guideways. An actuator is coupled to the jaw to cause movement of the jaw. A support supports at least a portion of the actuator. A biasing element is configured to urge the actuator to engage the support.
A jaw nut of a vise has a threaded bore with at least one opening on an end face. The jaw nut includes an inner annular groove concentric with a centerline of the threaded bore. The inner annular groove has a radius larger than a radius of the at least one opening from the centerline so as to provide at least a portion of an annular flange about the at least one opening having an inner annular surface facing in a direction opposite the end face. A threaded screw supported for rotation on the vise body threadably engages the threaded bore of the jaw nut. A brush seal is disposed in the inner annular groove with an outwardly facing annular surface engaging the inner annular surface of the inner annular groove.
A vise includes a vise body having a base with spaced apart rails joined to the base, each rail including a flange with a surface having a slot. A movable jaw assembly is slidable on the surfaces is driven by an actuator supported by the vise. A stationary jaw has a key configured to engage the slots and has a surface facing the movable jaw assembly. Fasteners secure the stationary jaw to the vise body, where all of the fasteners extend through the surfaces of the vise body between the slots and the surface of the stationary jaw facing the movable jaw assembly.
A main machine vise has a second auxiliary vise having independently movable clamping jaws attached to it with the auxiliary vise set to one side of the main machine vise and above a supporting surface of a machine tool table on which the main machine vise is mounted. The auxiliary vise has a movable jaw that moves in a plane generally perpendicular to the tool table on which it is mounted, while the main machine vise has a movable jaw that moves in a plane parallel to the tool table or surface on which it is mounted. The auxiliary vise is mounted on a bracket that offsets the clamping jaws of the auxiliary vise from the main machine vise so that work pieces can be independently clamped in each of the vises. The auxiliary vise includes a vibration reducing stabilizer for attaching to the tool table or support.

A vise assembly has a pair of moveable jaws mounted on guideways for movement toward and away from each other. The moveable jaws are driven by a vise screw on the vise body through head members of a pair of jaw nuts. The head members fit into cavities on the underside of the moveable jaws and have projections on first ends that have surfaces engaging mating recessed surfaces formed on one end of the cavities. Adjustable plungers are mounted on the head members and are extendable outwardly from a second end of the head members to engage and drive against surfaces of the cavities in a second direction. The adjustable plungers are adjustable in length so they can be retracted into mounting bores in the head members so the moveable jaws can be mounted on and removed from the head members, and extended so driving surfaces of projections on the head members and of the plungers are both in engagement with surfaces of the cavities.
A master jaw assembly used in a vise including a locking jaw, a detachable jaw and a clamping device disposed in the locking jaw, securely clamping the detachable jaw to the locking jaw. The locking jaw has a groove extending along an inner surface of the locking jaw defined by a first and second edge. The second edge is tapered inward and downward toward the base. The detachable jaw has a dovetail protrusion along one side surface thereof. The clamping device includes a plurality of specially-shaped clamp-nuts having a downwardly tapered edge, said clamp-nuts designed to receive one end of a double-ended threaded stud. The detachable jaw becomes fixed to the locking jaw by inserting the protrusion into the groove and torquing the studs to tighten the clamp-nuts downward against the protrusion such that the protrusion is clamped between the taper of the second edge and the clamp-nuts.
A five axis vise includes two separated vise body portions that are supported on a machine tool table or other support that fixes the vise body portions in position. The vise body portions have jaws spaced up from the machine tool table sufficiently to permit machining five surfaces of a work piece held in the jaws. A vise screw is rotatably mounted in one of the vise body portions, and extends to the other vise body portion to actuate a movable jaw on the other vise body portion. The vise screw is threaded into a jaw nut that has a drive surface that engages and drives a driven surface on the movable jaw, with the drive and driven surfaces being inclined relative to the axis of force application to provide a downward force component on the movable jaw as it is tightened. The vise screw is an assembly of a threaded shank or shaft and a hub that is rotatably mounted in one of the body portions, with the threaded shank or shaft being locked in position in the hub.
A controller (8, 30) provides adjustable power levels to heat a cooking device (20). A power flow controller (16, 36) can be used to adjust levels of power received from a power source (10).

Two station vise for manual or hydraulic operation with a quick-change stationary that can be carvable, hard or reversible. the stationary jaw having two precision through holes is placed on expanding pins, located on the top longitudinal rails of the vise body, that precisely position and tighten the stationary block in place. Two movable jaws connected by a tubular drive form an axially adjustable floating assembly. A manually turned tubular drive has an external threaded screw to move simultaneously the first jaw/nut and an internal thread that moves the second jaw/nut, on the opposite side of the stationary. Hydraulically parts are clamped at the two stations with a piston located in the second jaw/nut and connected axially with the first jaw/nut by the tubular drive. A setup-block located at the front jaw/nut keeps both jaws at proper position for loading and unloading of parts. The setup-block also allows for pre-clamping or retention of the part in the rear station before clamping.
