Patent

CA 2304918

An operating unit with an automatic tool changing device comprises a tool holding device having a clutch element for the mandrel. An expanding ring driven by a slider provides latching and unlatching operations for the tool holder with respect to the mandrel. With respect to prior operating units, the inventive operating unit provides the advantage of a less size, the mechanical strength of the tool holders being the same. Moreover, the use of a single mandrel, which is common to all of the tool holder devices, provides an operating unit which is much more simple and unexpensive than prior operating units.
