Abstract: A workpiece clamping device having a first base body on which a first clamping body is slidably supported in a clamping direction, as well as a second base body on which a second clamping body is slidably supported in the clamping direction. The two clamping bodies are in engagement with a threaded spindle. A contact surface is provided on each base body on the side that faces the other base body respectively. The contact surfaces are arranged with base body distance in the clamping direction. A centering body of the threaded spindle has centering surfaces that abut at one assigned contact surface respectively in order to position the threaded spindle in clamping direction without clearance as far as possible.

Abstract: A workpiece clamping device having at least one base body. A first clamping body and a second clamping body are movably supported on the at least one base body in a clamping direction. A threaded spindle extends along a spindle longitudinal axis. The spindle longitudinal axis is orientated in clamping direction. It has a first thread section for the first clamping body and a second thread section for the second clamping body. A first coupling body has a first counter thread portion and a second coupling body has a second counter thread portion. In a coupling position the counter thread portions are in engagement with the assigned thread section respectively. In a decoupling position the counter thread portion is disengaged from the assigned thread section. In this decoupling position a movement of the clamping bodies is possible without rotation of the threaded spindle.

Abstract: A method for clamping a workpiece that is first provided with depressions, wherein these depressions are, arranged in one row or a field having a grid distance of 3 mm. The grid distance is thereby the center distance of the depressions, the depth of which is preferably less than the length of the depressions measured in direction of the row of the depressions. The distances between the depressions preferably correspond approximately to the length of the depressions. The grid distance of 2.5 mm to 3 mm has proven to be an optimum for a wide range of usable workpieces and materials.

Abstract: An embossing device that serves for preparation of a combined form-fit and friction-fit clamping of a workpiece in a respective clamping chuck. The embossing device includes jaws having embossing teeth that are formed on insertion bodies. The insertion bodies include a penetration edge respectively with which they penetrate into the workpiece surface in order to create a depression with defined dimensions. For this a workpiece contact surface is formed on the insertion body, preferably in the proximity to the bar-like projection that stops the penetration process of the bar-like projection as soon as the workpiece contact surface gets in contact with the workpiece surface during the execution of the embossing process. Then the force required for movement of the jaw increases considerably from which a control device generates a switch-off signal for the operation device.

Abstract: The invention relates to a clamping device and is designed for releasably clamping a supporting body on which a workpiece can be arranged. The clamping device has a main body with receiving bores each for receiving a clamping bolt of the supporting body. Each clamping body can be moved linearly along the longitudinal axis thereof between a clamping position and a release position. The movement from the release position into the clamping position and/or conversely from the clamping position into the release position can be effected by means of an actuation device. Each clamping body has a clamping end which protrudes into an associated receiving bore in the clamping position. The longitudinal axes of the clamping bodies form a plurality of intersection points in a common projection plane parallel to which the longitudinal axes extend. In a preferred embodiment, at least three or four intersection points are formed.

Abstract: A clamping means system including a bearing device and clamping vices, which fit into the bearing device and respectively have on their base area machine coupling system and on their side faces and flanks a bearing receiving contour and a gripping receiving contour. The bearing receiving contour has the greatest play; the fit between the gripper and the gripper receiving contour is of moderate precision, while the precision of the machine coupling system is the greatest. The clear functional separation between the machine coupling system and the bearing receiving contour or gripper receiving contour allows a reliable low-cost system to be constructed. Furthermore, in the case of mixed partly automated systems, in which parts of the handling tasks are performed by the operator and other parts are performed by gripping robots, the handling is possible in an easy and intuitive way.

Abstract: A linear mechanical quick release fastener is operated by three movements with self-centering chucks and for mounting all types of compatible clamping devices for machining workpieces, especially on automatic precision machine tools. A bottom part has raised locking elements formed integrally in one piece one after another on a plane along a direction at right angles to a clamping direction and base jaws formed integrally in one piece, with a threaded hole for a clamping bolt and a screw element. A top part has recesses, one after another along a direction at right angles to the clamping direction, designed as a counterpiece of the locking elements. One recess is connected at an open front side to a mounting area recessed continuously, which is accessible from the top, and another recess is open on a front side. The top part can receive an upper plane of any compatible clamping device.

Abstract: A self-centering chuck is provided for accurately fixing the position of workpieces on tables. The chuck has a basic body with guide grooves, a threaded spindle with right-handed and left-handed external threads and a centrally arranged groove, two slides screwed onto an external thread each with a clamping jaw each in the head area and with sliding blocks in the foot area. The slides are guided axially in the guide grooves and on the threaded spindle. The threaded spindle is centered in a central piece and can be fixed and locked on the basic body and on the central piece by fastening means guided in the groove. The clamping jaws arranged on the head side on the slides have clamping surfaces on both sides and can be used on both sides. The slides can be screwed on both sides onto left-handed and right-handed external threads of the threaded spindle.
