Claims

[Scope of Claim for Utility Model Registration] A device for installing machine tools, etc. on the foundation via anchor bolts, consisting of a spherical seat 3 set on the foundation, a hollow cylindrical spherical leveling bolt, and a hollow cylindrical preload member. The spherical seat 3 has a concave spherical portion 3a coaxially formed on the upper surface thereof,
A convex spherical surface portion 2a corresponding to the concave spherical surface portion 3a is coaxially formed on the bottom of the spherical leveling bolt 2, and is fitted into the concave spherical surface portion 3a of the spherical seat 3 in a spherical insertion state. The spherical leveling bolt 2 has a male threaded portion 2b on the outer circumferential surface of the intermediate portion that engages with a female thread formed on a pedestal M of a machine tool, etc., and is screwed into the pedestal M. The protruding top outer peripheral portion of the spherical leveling bolt 2 has an integrally formed rotated means 2d, and has an inner diameter larger than the respective outer diameters of the protruding portion and the rotated means 2d formed at the top thereof. A hollow cylindrical preload member 1 having a hanging wall 1b that is larger than the axial length of the entire portion is seated on the upper part of the pedestal M at the lower edge 1c of the hanging wall, and The inner surface includes the protrusion of the leveling bolt 2 and the rotated means 2d concentrically and without contact, and includes the center through hole 3b of the spherical seat 3, the axial through hole 2c of the spherical leveling bolt, and the preload. The through hole 1a provided at the center of the top plate of the member 1 is extended in this order, and the protruding extension end of the top plate through hole 1a of the preload member 1 of the anchor bolt 4 fixed to the foundation is screwed in the same top plate surface. Installation equipment for machine tools.
