A workpiece holder device for workpieces to be machined on multiple sides, wherein the workpiece can be held axially and radially relative to the first axis between a first workpiece holder, operatively connected to at least one support spindle of the workpiece holder device and rotatable about the first axis, and at least one second workpiece holder, operatively connected to at least one drive spindle of the workpiece holder device and rotatable about the first axis, by force locking by means of a clamping force which can be built up in the manner of a vice between the first workpiece holder and the second workpiece holder in the axial direction of the first axis and acting on the opposite sides of the workpiece.

An embodiment of a vise may include a clamping structure having a first clamping jaw, a second clamping jaw positioned relative to the first clamping jaw, and a quick adjust jaw guide to maintain the first clamping jaw relative to the second clamping jaw. The quick adjust jaw guide may include a driving element to apply a force to move the first clamping jaw relative to the second clamping jaw, wherein the driving element comprises a release structure to release the applied force to facilitate rapid adjustment of the first clamping jaw relative to the second clamping jaw.

A vise with a sliding head which slides on an elongate body. A diagonal clamping screw passes through a hole in the sliding head and is threaded into a pin inserted in an internal sliding block. The internal sliding block has a toothed pattern which is able to interlock with a toothed pattern fixed to the body underneath the vise slides. The diagonal clamping screw provides force to lock the tooth patterns together and pull the head forward when tightened. A spring provides force to disengage the internal sliding block teeth and fixed teeth on the body when the diagonal clamping screw is loosened.

The present invention relates to a novel vise that operates in both a threaded and unthreaded mode. The vise includes a fixed block, a movable head, a rod, a ratchet mechanism, a threaded mechanism and a toggle mechanism. In the threaded mode, the movable head may only be moved by rotating the rod. In the unthreaded mode, the movable head may only be moved by applying force to the movable head in the desired direction of movement.

A band saw vice assembly for securing a substrate for cutting includes a base that has a first plate coupled to and extending vertically from a first side. A first bar, which is hollow, is coupled to and extends perpendicularly from the first plate. A second plate is coupled to and extends perpendicularly from a sleeve that is positioned around the first bar. A first slot and a second slot, which are aligned and perpendicular to the base, are positioned in the first plate and the second plate, respectively. An actuator, which is operationally coupled to the sleeve, is coupled to and positioned in the first bar. The actuator is positioned to motivate the second plate toward the first plate to frictionally couple to a substrate to fixedly position the substrate. The first and second slots are configured to insert a blade of a band saw to cut the substrate.

A clamping device (1) for holding a workpiece (10), in particular a cutting tool, during machining in a grinding machine, wherein peripheral grinding of the workpiece (10) is performed by means of a particularly approximately cup-shaped grinding wheel, wherein the clamping device (1) comprises a support unit (40) provided to be mounted on the grinding machine, a clamping unit (20) comprising a clamping anvil (12) supported in a clamping anvil holding element (22) and translationally drivable to apply a clamping force parallel to a clamping axis (16), and a drive unit (30) comprising a drive anvil (14) supported in a drive axis (18) and rotationally drivable for rotary orientating the workpiece (10) by means of the drive axis (18). The clamping unit (20) and the drive unit (30) are provided as individual components, which are releasably or slidably attached to the support unit (40) to form a workpiece spindle headstock of the grinding machine.

A vice including two clamping gaps (10, 20). A first body (1) includes a first jaw (11) and a second body (2) includes a second jaw (21), between which is formed a first clamping gap (10). A third body (3) is connected by an axis (9) to the first body (1), wherein the third body (3) includes a third jaw (31), which is adapted to rotate around the axis (9). The first body (1) includes a fourth jaw (41) opposite the third jaw (31), wherein between the third jaw (31) and the fourth jaw (41) is formed a second clamping gap (20).

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.
