Tail stock

摘要

A tail stock for compensating for the tapering of a workpiece comprises a center sleeve slidably and rotatably mounted in a housing and provided with a bore with a predetermined eccentricity for holding a center. An arm is secured at one end thereof to the center sleeve. A cylindrical member is mounted in the housing, being slidable in a direction perpendicular to the sliding direction of the center sleeve, and abuttingly engaging one side surface of the other end of the arm. A feed screw shaft is rotatably mounted on the housing and threadedly engages the cylindrical member. A supporting member is slidably mounted in the housing in an opposite relation with the cylindrical member for supporting the other side surface of the other end of the arm and a spring member is provided to urge the supporting member toward the other end of the arm.
