A workpiece holder device for a machine tool has a holder, which has a support part and a holder part. The support part supports the holder on a support device, preferably so that the holder can rotate about an axis of rotation. The holder part is set up to hold a workpiece directly or indirectly. To avoid, or at least minimize deviations from a desired alignment of the holder part based on elastic deformation of the holder due to the weight force of the workpiece, the holder has at least one mechanical or hydraulic pretensioning device arranged on or in it. The pretensioning device can be used to pretension the material of the holder, so that the pretensioning device applies a tensile stress or a compressive stress to at least one part of the holder. This can counteract a deviation of position due to an elastic deformation of the holder.

An adaptable assembly line work-piece processor for use at a work station includes, but is not limited to, a work-piece supporter. The adaptable assembly line work-piece processor further includes, but is not limited to, a reconfigurable interface assembly attached to the work-piece supporter. The adaptable assembly line work-piece processor still further includes, but is not limited to, a work-piece manipulator attached to the reconfigurable interface assembly. The work-piece supporter, the reconfigurable interface assembly, and the work-piece manipulator are configured to cooperate to sequentially support and manipulate a plurality of differently configured work-pieces.

A machining fixture configured to secure a blank part having part inner and outer circumferential surfaces, a part first axial face opposing a part second axial face, and at least two threaded part openings extending inwardly from the part second axial face and toward the first axial face. The machining fixture includes an annular body sized to be disposable upon a pallet of a machine table and has an upper surface including a substantially flat annular surface section, opposing lower surface and at least two through-holes extending between the upper and lower surfaces. At least two fasteners are disposed at least partially within a separate one of the at least two through-holes such that the at least two fasteners project upwardly from the upper surface, and the at least two fasteners are configured to threadedly engage a separate one of the at least two part openings to removably clamp the part second face against the body flat surface section.

A clamping jaw for the clamping of a workpiece, with a body and several clamping inserts arranged in mounting openings of the body made of a sintered material. The clamping inserts are designed in the form of cylindrical pins projecting relative to an end surface of the body and inclined relative to a lower base surface of the body with a clamping edge for forcing the clamping inserts into the workpiece.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

The present invention is provided with: a first processing position (A1) and a second processing position (A2) at which rough processing is performed on a workpiece (W); a third processing position (B1) at which final finishing processing is performed on the workpiece (W) that was processed at the second processing position (A2); flexible vices (7) provided to the first processing position (A1) and the second processing position (A2), the flexible vices (7) securing the workpiece (W) by clamping the same; and a quick clamping device (20) provided to the third processing position (B1), the quick clamping device (20) securing the workpiece (W) by means of a pin. The present invention is also provided with a control unit that controls a rough processing tool for performing rough processing and a final finishing processing tool for performing final finishing processing.

A vise jaw combination used with a milling machine vise to hold a work-piece having either parallel edges or non-parallel edges. Wherein, the milling machine vise in this application disposes at least one movable member having threaded holes cooperating with fasteners to join the movable member and the vise jaw combination comprising a vertical axis tool post and a rotatable vise jaw. Wherein, the vertical axis tool post comprises a detachable wall disposing correlative thru holes for cooperating with the threaded holes and fasteners disposed at the movable member, whereby the vertical axis tool post is joined to the movable member disposed at the milling machine vise. Wherein, the rotatable vise jaw consists of a one-piece structure disposing a thru hole for receiving a vertical shaft disposed at the vertical axis tool post, whereby the rotatable vise jaw is joined to the vertical axis tool post.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

The present invention relates to a clamping mechanism that is configured to securely hold a workpiece in a machine tool, such as, but not limited to a vertical machining center, or a horizontal machining center, etc. More specifically, the clamping mechanism is configured as a modular soft jaw. A multiplicity of clamping mechanisms can be used to cooperatively secure large workpieces. Furthermore, a multiplicity of clamping mechanisms can be incorporated into a job set-up so a multiplicity of workpieces can be processed concurrently. The present invention's clamping mechanism can be secured in orientations such as, but not limited to a machine tool table bed, a fixture plate, a tombstone, etc. The present invention's modular, soft jaw clamping mechanism can be used in conjunction with other work holding equipment, such as, but not limited to jigs, fixtures, tools, vises, clamps, etc.

A workholding apparatus for components having complex geometries or surfaces, which components are difficult constrain for the purpose of inspection, addresses the problem of adequately constraining such components in a convenient and cost-effective manner so that they do not move during inspection, while also making all or most critical features accessible to the inspection instruments being used. A method teaches how to eliminate setup changes between different components through the use of inexpensive modular attachments. These attachments are in the form of a single piece thermoplastic part which is affixed to each component having also reference features that can be interlocked into a common base fixture for more efficient inspection operations.
