ABSTRACT:
A rotary indexing device for use in a group of treatment stations, includes at least one respective tensioning device for exchangeable tool holders disposed in a treatment zone. The rotary indexing machine has a rotary indexing unit with a lift-and-turn device on which support elements for tool holders are disposed. The lift-and-turn device of the rotary indexing unit is provided with a piston rod on which a first coupling element is mounted in a rotationally fixed manner. The first coupling element can be engaged with a further coupling element disposed above it by the lift stroke of the piston rod. The coupling element encloses the piston rod and is driven by a motor. The piston rod is rotationally fixed during the lift stroke.
