Claims

[Scope of utility model registration request]

A tool holder is attached to the spindle at a fixed position substantially symmetrical to the center of the spindle and has a shape substantially symmetrical to the center of the spindle, and the tool holder is slidably inserted into a through hole at the center of the spindle, and the tool holder side end a drawbar having a protrusion or groove inclined with respect to the axial direction of the spindle in the center of a side surface of the drawbar; a mechanism for pulling the drawbar toward the side opposite to the tool holder along the axial direction of the spindle; A wedge block having an inclined groove part or an inclined convex part combined with the groove part and whose end face on the tool holder side is inclined with respect to the axial direction of the main spindle, and which moves in a direction perpendicular to the axial direction of the main spindle by the tensile movement of the drawbar. , a member that restricts the movement of the wedge block toward the side opposite to the tool holder, and a member that is interposed between the wedge block and the tool holder, and has an inclined surface that makes sliding contact with the inclined end surface of the wedge block, and has a member that restricts the movement of the wedge block toward the opposite side of the tool holder. A push block that pushes out and elastically deforms the part of the tool holder immediately below the back of the tool along the axial direction of the spindle through the movement of the wedge block, and restricts the movement of this push block in a direction perpendicular to the axial direction of the spindle. A tool axial position correction device comprising: a member for correcting a tool axis direction;
