A clamping plate for receiving at least one workpiece clamping device or a workpiece, the clamping plate including: a support surface for the at least one workpiece clamping device or the workpiece, the support surface is penetrated by a plurality of openings for receiving clamping bolts of the at least one workpiece clamping device, clamping slides being arranged in the clamping plate, the clamping slides each project with one end into one of the plurality of openings in a clamping position and are located outside the one of the plurality of openings in a release position, —a clamping wedge, which is movably arranged in the clamping plate and is operatively connected to the clamping slides via at least one of a body formed resiliently yielding in several directions, a hollow body, an annular body, and a hollow cylinder.

Clamping device and workpiece holding device with a clamping device

A clamping device and a method for handling a workpiece or a unit comprising a workpiece and a workpiece holder. An automatic workpiece exchange is enabled by using a tool spindle. For this a spindle adapter is present that can be releasably connected with the workpiece holder. By means of the spindle adapter, the unit comprising the workpiece and the workpiece holder can be transported. The clamping device can be switched between a release condition and a clamping condition by means of a movement of an operating element. This movement can be carried out by means of the tool spindle, in that the tool spindle engages the operating element directly or indirectly by means of the spindle adapter or an operating tool.

Clamping device and method for handling a workpiece

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.

Workpiece clamping device

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.

Workpiece clamping device with coupling body between clamping body and threaded spindle

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.

Device and method for clamping workpieces

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. More particularly, four clamping bodies can be present, each with a longitudinal axis, wherein four intersection points are formed, in each of which two of the available longitudinal axes intersect.

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.
