摘要

The device (1) for the exchangeable attachment of a power-operated chuck (11) to the spindle (3) of a machine tool consists of a flange (31) which accommodates the power-operated chuck (11), is attached to the spindle (3) and is in the form of a centring and clamping part which has as holding members two or more head bolts (33) which are arranged so as to be distributed over the periphery, project at the end face and can be inserted in recesses (21) made in the body (12) of the chuck (11) and can be restrained with this chuck body (12). This design enables the power-operated chuck (11) to be attached to and removed from the spindle (3) in a short time with simple manipulation. Operationally safe mounting of the power-operated chuck (11) is always guaranteed. IMAGE
