Method of manufacturing a modular clamping device for rotationally symmetrical bodies and clamping device manufactured therewith

A method of manufacturing a modular clamping device for clamping a rotationally symmetrical body on a spindle head of a motor spindle to drive the rotationally symmetrical body to rotate about a longitudinal axis of the clamping device, the modular clamping device comprising a clamping element configured to establish a clamping connection with the rotationally symmetrical body and a first intermediate piece,

• the method comprising the steps of:
• providing a first intermediate piece assortment comprising a plurality of prefabricated, standardized first standard intermediate pieces, each of said first standard intermediate pieces having a proximal end and a distal end, wherein each of said first standard intermediate pieces provides at its proximal end an interface to a base unit arranged on the spindle head, and wherein each of the first standard intermediate pieces provides at its distal an interface end for a second intermediate piece;
• selecting a desired first intermediate piece from the first intermediate piece assortment;
• manufacturing the clamping element;
• providing a base unit assortment comprising a plurality of prefabricated standardized base units, each of the standard base units having a proximal end and a distal end, wherein each of the standard base units provides an interface to the spindle head at its proximal end, and wherein each of the standard base units provides an interface to a first standard intermediate piece from the first intermediate piece assortment at its distal end;
• selecting a desired base unit from the base unit assortment;
• arranging the first intermediate piece relative to the clamping element in such a way that the first intermediate piece is arranged in axial direction with respect to the longitudinal axis between the spindle head and the clamping element when the clamping device is mounted to the spindle head;
• arranging the selected base unit relative to the first intermediate piece such that the base unit is arranged in axial direction between the spindle head and the first intermediate piece when the clamping device is mounted to the spindle head,
• wherein the clamping device comprises a support element for axially supporting the rotationally symmetrical body when the rotationally symmetrical body is clamped on the clamping device,
• wherein the clamping device comprises a pneumatic seat checking device comprising at least one measurement nozzle arranged in the support element,
• wherein the first intermediate piece has a decentrally extending conduit bore for guiding a measurement fluid for the measurement nozzle,
• wherein the first intermediate piece comprises a continuous central bore along the longitudinal axis,
• wherein the conduit bore opens into the central bore of the first intermediate piece at an opening, so that the measurement fluid can be guided through the central bore of the first intermediate piece to the measurement nozzle,
• wherein the clamping device comprises at least one connection conduit for the measurement fluid, wherein the at least one connection conduit is configured to guide measurement fluid that has been guided into the central bore of the first intermediate piece to the measurement nozzle,
• wherein the clamping device comprises an actuating element for actuating the clamping element, and
• wherein the actuating element is arranged in the central bore of the first intermediate piece and is axially movable along the central longitudinal axis in the central bore.
