ABSTRACT:
This invention relates to multi-spindle machine tools of the kind comprising a plurality of tool-carrying spindle heads stored in at least one magazine, said spindle heads being exchangeable as desired for the purpose of performing a tool change, a selected spindle head in the magazine being substituted for the one currently secured to the spindle head carrier, this latter spindle head being released from the carrier and conveyed to its predetermined storage space in the magazine, whereas the other spindle head selected in each case is withdrawn from the magazine and secured to the spindle head carrier.
According to this invention, the spindle head carrier is constructed as a turret rotatable around a longitudinal axis and is provided with spindle head holders distributed along its outer periphery. Each magazine laterally co-ordinated with the turret has storage spaces for the spindle heads which are to be stored, the holders and the storage spaces being located at identical radial distances from the longitudinal axis. For the purpose of reciprocal transfer of spindle heads the holders are placeable in alignment by rotation of the turret, and each holder of the turret is turnable to an operating position in which the spindle head present in the holder in question is couplable to a spindle drive system stationarily arranged on the magazine.
