Claims

[Claims for Utility Model Registration] (1) A tool holder for taper hole machining that is detachably attached to the main spindle of a machine tool, a rotating shaft that is inserted into the main spindle and transmits the rotation of the main spindle, and this rotating shaft. a housing that rotatably supports the machine tool and is fixed to a fixed part of the machine tool with a detent; a screw shaft that is freely movable and has a threaded portion at one end; a rotating body that is threadedly engaged with the screw shaft and is rotatable around the screw shaft axis and whose movement in the screw shaft axial direction is restricted; a rotation transmitting means for relatively rotationally transmitting the rotation of the rotary shaft to the rotating body; a rotation transmitting means supported by the housing so as to be rotatable on an axis concentric with the screw shaft, and transmitting the rotation of the rotary shaft and transmitting the rotation; A guide member is provided with a guide hole in a direction inclined at a predetermined angle from the shaft, and the guide member is movable forward and backward along the guide hole of the guide member, and rotates together with the guide member by engaging the screw shaft with a slider. A taper machine comprising a tool shaft equipped with a tool, which is rotated by the rotation of the rotary shaft and is fed in a guide direction inclined at a predetermined angle from the rotary shaft to machine a tapered hole. Tool holder for hole machining. (2) The tool holder for tapered hole machining according to claim 1, wherein the tool shaft and the guide member are provided so as to be replaceable.
