Vertical machining center lathe bed

The invention discloses a vertical machining center lathe bed and belongs to the field of machining center lathe beds, the vertical machining center lathe bed comprises a supporting seat and an anchor bolt, a mounting groove used for mounting and fixing the anchor bolt is formed in the outer surface of the supporting seat in an embedded mode, the upper end of the anchor bolt penetrates to the inner side of the mounting groove, and a locking sleeve is in threaded connection with the outer surface of the anchor bolt. A limiting assembly is arranged on the inner side of the anchor bolt and used for clamping and limiting the locking sleeve and the anchor rod, and the upper side of the locking sleeve is in contact with a pressing sleeve in an attached mode. When the pressing sleeve and the locking sleeve are loosened, the pressing sleeve is extruded through the pressing rod, so that the friction force between the pressing sleeve and the locking sleeve is increased, the connection between the locking sleeve and the
