節装置。[Claims for Utility Model Registration] A cutting tool that is attached to a boring bar attached to the main shaft of a machine tool so as to be movable along its radial direction and has a locking piece that projects in the axial direction; a freely provided eccentric cam; a clamping block positioned between the eccentric cam and the cutting tool, which presses the cutting tool and fixes the cutting tool in position by being pushed by the rotation of the eccentric cam; a reciprocating table that moves back and forth; a fitting member that is placed on the reciprocating cable and that fits into the eccentric cam when the table approaches the eccentric cam; a rotating motor that rotates the fitting member; and an engaging member of the cutting tool. A moving block that engages with the stop piece, a feeding unit that moves the moving block along the radial direction of the boring bar, a feeding motor that drives this feeding unit, a proximity switch that detects the position of the tip of the cutting tool, and the aforementioned An automatic boring diameter adjustment device, comprising: a control unit that receives a detection signal from a proximity switch and controls a forward/backward table, a rotation motor, and a feed motor.
