Clamping device and method for handling a workpiece

A combination, comprising:

• a machine tool, comprising:
• a tool spindle, and
• a spindle adapter having a counter coupler, wherein the spindle adapter is adapted to be held by the tool spindle;
• and
• a clamping device for clamping a workpiece holder on the machine tool, comprising:
• a base having a support surface for receiving the workpiece holder, and
• an operating device arranged on the base, the operating device comprises at least one slider,
• wherein the base comprises an operating element, which is moveable between a first position and a second position along a path about a height axis, the path being a circular path or a circular arc path, and where the height axis intersects and is orientated orthogonal to the support surface,
• wherein the operating element is an operating ring comprising a coupler, which is configured to be releasably coupled with the counter coupler of the spindle adapter,
• wherein the clamping device is in a release condition releasing the workpiece holder, if when the operating element is in the first position, and the clamping device is in a clamping condition clamping the workpiece holder when the operating element is in the second position, and
• when the tool spindle holds the spindle adapter and the counter coupler of the spindle adapter is brought into engagement with the coupler of the operating element, rotation of the spindle adapter about the height axis results in the operating element being rotated about the support surface and along the path about the height axis such that the operating element is moved between the first position and the second position.
