Claims

[Scope of Claim for Utility Model Registration] (1) A type of tailstock in which the center is not located on the same axis as the ram for advancing and retracting the center, but is eccentrically attached to the ram, and is spaced apart from the ram. A support shaft supported movably in the axial direction on the tailstock with parallel axes is connected to the ram by a connecting member, and the support shaft is directly connected to the connecting member so as to sandwich the ram and be located on the opposite side of the support shaft. , or a tailstock with a center attached indirectly. (2) The tailstock according to claim 1 of the utility model registration claim, wherein the support shaft is supported by being clamped by outer rings of upper and lower bearings in the tailstock. (3) The tailstock according to claim 2 of the utility model registration claim, wherein the outer circumferential surface of the outer ring of the bearing is hourglass-shaped with a concave radius of curvature larger than the radius of curvature of the outer circumferential surface of the supporting shaft supported on the outer circumferential surface. . (4) The tailstock according to claim 2 or 3 of the utility model registration claim, in which the upper and lower bearings can be vertically adjusted. (5) The tailstock according to claims 1 to 4, wherein the center is attached to the connecting member via a center holder. (6) Utility model registration claim No. 5 in which the center holder is attached to the connecting member in a position adjustable manner.
Tailstock as described in section.
