Example systems and methods of a system for mounting a grinder/polisher sample holder are provided. The system includes a platform having one or more fasteners, upon which one or more mounting fixtures are arranged and mounted. The one or more mounting fixtures are configured to secure a sample holder in place for testing of the samples, such as a hardness test. One or more of the mounting fixtures may include mounting brackets to support the sample holder, and to fix an orientation and/or position of the sample holder. In examples, the mounting fixtures have interfaces to contact and support the sample holder when the sample holder is arranged within the system.

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.

The invention relates to a clamping arrangement with a clamping device (1) which is able to be fastened on a clamping base, and with a clamping element (26) able to be tightened thereon. The clamping device (1) has a clamping module (2), provided with clamping members (15), which is able to be fixed by means of a fixing element (3) on the clamping base, wherein the fixing element (3) is configured such that the clamping module (2) is thus fixed in the X-Y plane in a floating manner on the clamping base. The clamping module (2) is displaceable in the fixed state of the fixing element (3) with respect to the fixing element (3) in the X-Y plane, but is non-displaceable in Z-direction, wherein the fixing element (3) is provided with Z-support surfaces (24) for the clamping element (26). Such a clamping arrangement is suitable in a particularly advantageous manner as a module for constructing a large clamping system, with which thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with high repeat accuracy, without the clamping system being overconstrained geometrically/mechanically in the X-Y plane.

A precision locating fastening device for securing a part. The device includes a drive screw, a base member, and a stop member. The drive screw has a gripping surface. The base member houses the drive screw and has a precision locating surface. The part is retained and located adjacent the precision locating surface relative to a fixture plate. The drive screw has one or more keyed ends. The stop member is replaceable to maintain precision and accuracy while locating and retaining the part. The device is incorporated in a system where a first keyed end of a first fastening device, a second key of the first fastening device, or the keyed end of a drive screw of a second fastening device is adjusted from either the first side of the fixture plate, the second side of fixture plate, or both to retain and locate the part on the fixture plate.

The tilt prevention structure for a test seat contains a track element having at least a notch configured on a top side of the track element, a base member having a trough on a bottom side for detachably accommodating the track element and at least a fastening hole on a front side connecting the trough, and at least a limiting element plugged into the fastening hole. The track element is fixedly configured on a test apparatus. The base member is then joined to the track element by embedding the track element in the trough. The limiting elements are plugged into the fastening holes so as to prevent the base member from tilting. The base member can be moved along the track element so as to align the adjustment member against an object to be tested.

The application is related to adjustable supports for holding objects in one or more desired fixed orientations, including but not necessarily limited to objects that lack uniformity as to size and/or shape and/or weight.

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.

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.

The invention provides an adapter for a dental milling block holder with a dental milling block (52 and 54) or dental grinding block, which is attached to a dental milling block holder, in particular glued on, wherein the dental milling block holder is provided with a round shank which is mounted in the adapter (40). It is characterized in that the adapter (40) is provided with at least one internal thread (92) for the mounting of a fastening screw (31) which acts on the shank, to which fastening screw (31) inside the shank mount of the adapter (40) of the fastening screw (31) positioned opposite of it, at least one in particular elevated, in particular at least two elevated clamping surfaces (74 and 76) are formed against which the shank abuts.

A wedge drive designed to redirect a vertical pressing force into a horizontal, linear working motion, comprising a sliding element and a sliding element holder which are two guide elements on which a guide device with a sliding plate assembly which has two side sliding plates and the central guide is arranged, which sliding plates are distanced from each other in the transverse direction perpendicular to the sliding direction. The central guide is arranged between the two sliding plates and is fastened to the sliding element. Each sliding plate lies against the sliding element holder by at least the following contact surfaces wherein one contact surface lies on a first plane and extends in the transverse direction and a second contact surface lies on a second plane at a distance from the first plane and also extends in the transverse direction and a third contact surface extends perpendicularly thereto.
