CLAMPING CELL WITH FORCED OPEN FUNCTION

摘要

A clamping apparatus is provided employing a forced open function to achieve accurate frictionless adjustment. In an embodiment, a shaft (60) is held by the inventive clamping cell (40) which comprises a clamping block (302) and a screw (304) with two different thread sizes. Nuts (306, 308) with different threads are respectively backed in and out as the screw (304) is turned. The shaft position is thus adjusted to within a required tolerance without causing any friction forces on the shaft (60).
