Abstract

The invention concerns a work carrier changeover device for machine tools, with a work carrier transfer device for moving the work carrier (16) between a machining station (15) and a tooling station (21). The work carrier transfer device has a coupling element (25) rotatable around a vertical axis and two opposing coupling points (26, 27) for the coupling of work carriers (16). The coupling element (25) is pivotably mounted at free end section of a swivel arm (24) capable of swivelling around a vertical axis.
