Claim 0:
1. A tool gripper assembly arrangement for holding a tool accurately in a holder plate, comprising:
an elongated gripper bore opening within the holder plate, for receipt of an elongated tool within that gripper bore opening, the elongated gripper bore having a longitudinal axis;
a pair of thin, flexible, curvilinear gripper wings having a generally semicircular contour extending partially around the gripper bore opening, the pair of gripper wings are bisected by the longitudinal axis and a gap extends between end surfaces of the gripper wings, the gripper wings are arranged between a wedge receiving channel and the gripper bore opening;
an elongated wedge receiving channel within the holder plate is disposed radially outwardly of the gripper wings which are adjacent the gripper bore opening;
an elongated gripper-wing-pressing-truncated wedge arranged within the elongated gripper wedge receiving channel;
a side-positioned adjustment bolt receiving bore arranged in a side edge of the holder plate; and
an adjustment bolt arranged within the side positioned adjustment bolt receiving bore is configured to bias both the truncated wedge and the pair of gripper wings radially inwardly toward the longitudinal axis of the gripper bore opening and close the gap between the pair of wings to change the contour of the bore to a perfect tool gripping-circle and centrically locate the tool within the elongated gripper bore.
