The invention relates first to a device for applying a pressing force, comprising two pressing jaws (25, 26) which can be moved linearly relative to each other via a hydraulic piston-cylinder assembly (8). Additionally, an actuation cone (13) is provided for an expanding device (36), said cone carrying out a forward and rearward movement depending on an actuation of the hydraulic piston-cylinder assembly (8). In order to advantageously develop the device, the actuation cone (13) is connected to the hydraulic piston (9) of the hydraulic piston-cylinder assembly (8) for the forward and rearward movement. The invention further relates to a device for applying a pressing force, comprising two pressing jaws which can be moved linearly relative to each other and which can be held in receiving areas and to a pair of pressing jaws.

An improved floating jaw assembly to a machinist vise assembly capable of holding a plurality of individual workpieces, the vise assembly generally including a base with a way or ways, a fixed jaw mounted on the ways, at least one movable jaw slidably mounted on the ways to move toward and away from the fixed jaw on a longitudinal axis in such a manner that at least one workpiece can be securely held between the fixed jaw and the at least one movable jaw, and a mechanism for moving the movable jaw toward and away from the fixed jaw to clamp and unclamp workpieces. The floating jaw assembly includes at least one floating jaw plate attached to the vise assembly with means for adjustable movement of the floating jaw plate(s) along the longitudinal axis of the vise assembly and for articulated movement of the floating jaw plate(s) in a plane substantially parallel to the base of the vise assembly and about an axis perpendicular to the longitudinal axis of the vise assembly so that the floating jaw plates can, in cooperation with adjoining jaws or plates, adjust to and securely hold workpieces. In addition, the floating jaw assembly includes a means of forcing the at least one floating jaw plate downward and securely against the ways of the vise assembly.

Embodiments described herein relate to a vise, for example, for holding material to be cut with a saw, for example, power saw. In one embodiment the disclosed vise includes a base member, a pair of fixed jaws attached to a first side of the base member, the pair of fixed jaws being substantially aligned and spaced apart defining a first gap therebetween, a handle attached to a second side of the base opposite the first side, and a pair of moveable jaws adjustably connected to the pair of fixed jaws, the pair of moveable jaws being spaced apart defining a second gap therebetween, wherein a center of the second gap is substantially aligned with a center of the first gap.

A clamping apparatus includes a spindle body and a nut element to be screwed together for decreasing a spacing between first and second clamping elements to clamp an object disposed therebetween. The nut element has roller bodies with a defined roller engagement structure axially rotatably secured on a receiving body of the nut element and distributed in circumferential direction. A plurality of engagement regions distributed and/or spaced apart on the spindle body each have one spindle body engagement structure. The roller engagement structures of the roller bodies engage or can engage the spindle body engagement structures of the spindle body. The nut element can be screwed to the spindle body by the mutually engaged engagement structures of the spindle body and of the roller bodies, in particular with rolling of the roller bodies on the spindle body. An apparatus and a vise having the clamping apparatus are also provided.
