Claims

[Scope of Claim for Utility Model Registration] (1) In a tailstock device that is used by arranging a tailstock on a lathe bed and fixing the tailstock on the lathe bed at any position from the end face of the lathe main shaft. , an upper surface of the lathe bed protrudes to form a bed portion, a lower surface of the frame of the tailstock protrudes to form a convex portion, and a side surface of the bed portion and a side surface of the convex portion are provided. A space is formed, a side surface of the convex part is formed into a tapered surface, and a tapered gib having a tapered surface that presses against the tapered surface is slidably attached to the space, and the bed portion is attached to the bed through the tapered gib. The tailstock device is characterized in that the tailstock is fixed on the lathe bed by fixing the convex portion in a press-contact state. (2) In a tailstock device that is used by arranging a tailstock on a lathe bed and fixing the tailstock on the lathe bed at an arbitrary position from the end face of the lathe main shaft, the upper surface of the lathe bed protrudes. The lower surface of the frame of the tailstock is projected to form a convex portion so as to be inserted between the inner surfaces of the respective bed portions, and the convex portion facing the inner surface is formed so as to form a convex portion. Both side end surfaces of the section are formed into tapered surfaces, and tapered gibs are slidably attached to two spaces formed by the inner surface and the side end surface, and the convexity is formed on the inner surface through each of the tapered gibs. A tailstock device, characterized in that the tailstock is fixed on the lathe bed by fixing the parts in a press-contact state. (3) The tailstock device according to claim 2, wherein the side end surface of the convex portion, the taper gib, and the inner surface of the bed portion are configured symmetrically with respect to a vertical plane passing through the center of the lathe main shaft. . (4) Fine sliding adjustment of the taper gib relative to the convex portion within the space is achieved by a notch formed in the taper gib that is screwed into a female thread formed on a side end surface of the convex portion facing the taper gib. 3. Tailstock device according to claim 2, which is achieved by an adjustment screw engaging the tailstock.
