なしたことを特徴とする自動偏心装置。 A first eccentric plate having an eccentric hole fixed to the tip of the main spindle in an eccentric device that is provided at the end of the main spindle of a lathe equipped with a main spindle fixed position stopping device and grips the workpiece by aligning the eccentric portion of the workpiece with the axis of the spindle. and the first
a plate that is fitted into an eccentric hole of an eccentric plate and is capable of turning and moving in the axial direction; and an eccentric boss portion fixed to the plate and having the same eccentricity as the first eccentric plate on the tip surface, and a turning gear on the outer periphery. a second eccentric plate having a large diameter portion carved in the center hole, a power chuck fixed to the second eccentric plate, and a collar portion fitted into the large diameter portion of the center hole of the second eccentric plate. a clamper that moves the plate in the axial direction by fluid pressure drive, a pair of kerbic gears that are fixed to the plate and the first eccentric plate, respectively, and perform index positioning and clamping by the movement of the clamper, and the swing gear. and an index drive gear member that engages with the drive gear when necessary to perform an index drive, and indexes the maximum eccentric points of the first and second eccentric plates so that they are at 180 degrees to each other, and aligns the center of the gripping claw between the main shaft and the power chuck. An automatic eccentric device characterized in that it performs normal turning processing with the second eccentric plate coaxial, rotates and indexes the second eccentric plate, and shifts the maximum eccentric point to enable machining of eccentric parts.
