Abstract
The invention concerns a centring device for centring a chuck on a securing portion in particular of a rotating spindle of a machine, wherein a tapered portion corresponding to a mating tapered portion on the chuck side is provided on the securing portion in such a way that the tapered portion and/or the mating tapered portion is/are formed so as to yield elastically in the axial direction such that, after the tapered portion comes into contact with the mating tapered portion, the chuck can be moved further in the axial direction, at least to a limited extent, as a result of an axial pulling-in force until the chuck comes to lie against a stop on the securing portion side. The invention likewise concerns an associated locking device.
