Rotational power servo toolpost

A rotational power toolpost, comprising:

• a turret base including a protruding joint pan and a bearing sleeved on the protruding joint part;
• a turret pivotally connected with the turret base through a pivot shaft that is pivotally connected with the protruding joint part of the turret base and eccentric to the bearing, and comprising a turret main body having a plurality of mounting holes on a side surface thereof;
• and a retaining ring having a plurality of driven gears corresponding to the mounting holes pivotally connected to a rim of the retaining ring;
• wherein the other ends of the driven gears are pivotally mounted into the mounting holes respectively;
• at least one tool holder inserted into the mounting hole, wherein each tool holder has at least one tool and a connection set engaged with the driven gear;
• and
• a tool-bolder-rotating device mounted on the turret base and comprising a servomotor, a transmission pole, a transmission gear connected with the transmission pole, and a ring gear engaged with the transmission gear, the bearing of the turret base fitted into the ring gear;
• wherein the transmission pole connects with the servomotor and is inserted into the turret;
• and the eccentrically disposed ring gear engages with and drives one of the driven gear;
• the driven gear drives the connection set in the tool holder, thereby rotating the
