Abstract:
1. A twin disk type tool turret mechanism of a machine, comprising: an internal tool turret for holding a plurality of tools thereon; an external tool turret for holding a plurality of tools thereon; an external toothed ring securely connected to the internal tool turret; the external toothed ring having a gear fitted thereto; a central shaft securely connected to the external tool turret; the central shaft having a gear fitted thereto; a power switching member capable of providing power to the internal and the external tool turrets through the external toothed ring and the central shaft respectively; the power switching member including; (1) a power source, which is either a servomotor or a stepper motor, and which has a bevel gear secured on an power output shaft thereof; (2) a rotary sleeve engaging the bevel gear of the power source at a bevel gear thereof; the rotary sleeve having a plurality of engaging teeth on a middle section thereof; (3) a transmission shaft passed into the rotary sleeve and capable of being disengageably engaged with the engaging teeth of the rotary sleeve at engaging teeth thereof for power to be passed on to the transmission shaft through the rotary sleeve; the transmission shaft having a pinion fitted to one end thereof engaged with the gear of the external toothed ring such that the internal tool turret will be made to rotate for allowing a tool choosing action by the power source when the transmission shaft is engaged with the rotary sleeve; and (4) a transmission sleeve passed into the rotary sleeve and capable of being disengageably engaged with the engaging teeth of the rotary sleeve at engaging teeth thereof for power to be passed on to the transmission sleeve through the rotary sleeve; the transmission sleeve having a gear fitted to one end thereof engaged with the gear of the central shaft such that the external tool turret will be made to rotate for allowing a tool choosing action by the power source when the transmission sleeve is engaged with the rotary sleeve; the transmission shaft having a transmission shaft piston secured thereon, which is actuated and displaced by means of power provided thereto through passage conduits, such that the transmission shaft and the transmission sleeve will be displaced to change between the respective engaging positions and the respective disengaging positions thereof when the transmission shaft piston is displaced with power provided thereto through the passage conduits.
