The tool-less vise jaw system comprises a stop block and two jaw plates. The jaw plates couple to the jaws of a vise that is used in conjunction with an industrial machine or tool. One jaw plate comprises a plurality of holes into which pins projecting from the stop block may be inserted. One pin extends through the jaw plate into the space between the vise jaws. The pin is used as a reference point during edge finding. Later, when switching from one job to another, the stop block may be moved to a different position in the plurality of holes and a digital readout may be programmed to change an X-axis offset by an amount corresponding to the distance that the pin was moved, thus eliminating the need to edge find again.

A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

A dual-cam device is described configured to be engaged with a rail and a stopper for clamping at least one object. The dual cam device comprises a jaw; a body; a member connecting the jaw and the body wherein the member has a member-base configured to associate with and slide on the rail; and a lever pivotally connected to the member, wherein the lever has a first cam and a second cam and wherein the lever is configured to be tilted from an open position to a clamp position and vice versa. During tilting the lever from an open position to a clamp position in which the object is clamped, the first cam causes the dual cam device to secure emplacement position of the dual cam device to the rail and then the second cam causes the dual cam device to press and clamp the object by the jaw against the stopper. It is further described a clamping apparatus that comprises at least one dual cam device; at least one rail having a channel; and at least one stopper.

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 by means of mounting pins and openings in the floating jaw plates for adjustable movement of the floating jaw plates along the longitudinal axis of the vise assembly and for articulated movement of the floating jaw plates 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 as the at least one movable jaw moves toward the fixed jaw, along with the intermediary at least one floating jaw plate, when clamping a workpiece. The floating jaw plates can be bisected longitudinally so that each bisected jaw plate can move independently of the bisected jaw plate and allow for even greater adjustable and articulated movement of each bisected floating jaw plate. The floating jaw assembly can be added as an accessory to a conventional vise assembly.
