Indexing table for bringing workpiece and/or workpiece support to different processing positions, has clock ring rotatable around rotational axis and locked relative to base part via clock ring-side coupling unit in working position

摘要

The table (1) has a clock ring (9) rotatably around a central rotational axis (D) relative to a base part (3). A base part-side controllable clock drive (13) is designed as a pneumatic drive for rotation of the ring between working positions. A clock ring-side coupling unit is movable between a rotational position and a locking position, so that the drive is coupled to the ring for rotation via the coupling unit in the rotational position. The ring is decoupled from the drive in the locking position and locked relative to the base part via the coupling unit in the working position.
