The positioning pin has a pin body and a biasing element. The pin body defines a slit through which at least a portion of the biasing element is able to extend through. The pin body can be configured to be at least partially inserted into a working surface hole and help position an object. The biasing element has an engagement element that is able to bias the working object in a direction of the slit.

A clamping device includes a clamping chuck and a clamping element, which can be clamped thereto. The clamping chuck has a receiving opening for the clamping element and clamping members for clamping the clamping element in the receiving opening. The clamping element is elongated, while the clamping chuck is provided with an elongated receiving opening for the clamping element. A resiliently flexible centering element, which aligns the clamping element in response to the insertion into the receiving opening at right angles to the longitudinal axis of the receiving opening, is arranged on the clamping chuck in the insertion area of the receiving opening. Such a clamping device is suitable in clamping systems by means of which large to very large workpiece carriers can be clamped in the work area of a machine tool in a repeatably accurate manner.

A work holding clamp system for securing a workpiece to a work surface having a work surface T-slot arranged along an ‘X’ axis, comprised of a base plate secured to the work surface and having a plurality of T-slots, each of the plurality of T-slots are aligned with one of a plurality of axis including at least the ‘X’ axis and a ‘Y’ axis that is transverse to the ‘X’ axis. The work holding clamp system includes a workholding element selected from the group consisting of wedge clamps, pivot clamps and workstops, that may be secured within a T-slot of the plurality of T-slots provided in the base plate.

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 workpiece clamping device able to perform a set-up changing operation for clamping members depending on the kind of a workpiece to be processed, at a low cost, by a simple method. The workpiece clamping device includes a bracket, a movable part which is movable with respect to the bracket, a clamping member to be attached to and detached from the bracket or the movable part, to clamp a workpiece, and a detachable device for detachably coupling the bracket or the movable part to the clamping member.

Automated fixture layout is approached in two distinct stages. First, the spatial locations of clamping points on the work piece are determined to ensure immobility of the fixtured part under any infinitesimal perturbation. Second, spatial locations are matched against a user-specified library of reconfigurable clamps to synthesize a valid fixture layout or configuration that includes clamps that are accessible and collision free. The spatial locations matching during the second stage can be the same spatial locations chosen in the first stage to ensure immobility, or a different set of spatial locations.

An angle element for a welding and clamping table system includes an L-shaped profile, a base plate releasably fastened at one end of the L-shaped profile and provided with a system borehole of the welding and clamping table system, and a member releasably fastened at another end of the L-shaped profile and selected from the group consisting of a further such base plate and a clamping plate which is provided with several threaded boreholes to accommodate various hole patterns of quick-change clamps.

The invention refers to a chuck pallet (1.3) with solid groove-sidewalls (2.3) for clamping chucks (1.1), whereby the x-y-references (2.5) of the chuck pallet (1.3) are allocated in the same plane (2.1) as the z-references (2.1) and the x-y-references (2.5) are also allocated at the solid groove-sidewalls (2.3). The solid groove-sidewalls (2.3) have thereby a tapered profile.

A clamp to retain a block of material on a machining table including a body having a first face, a first front face oriented toward the machining table and the block of material when in use, a nose projecting relative to the first front face having a second front face parallel to the first front face, first and second edges connecting the first and second front faces, and at least one internally threaded hole opening at least partly at the level of the second front face with an axis forming a non-zero angle with the first face and the second front face, at least one grub screw screwed into the internally threaded hole having a pointed free end configured to penetrate into the block of material when in use when screwing in the grub screw, and a connecting system to demountably connect the clamp to the machining table.

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.
