するターンブローチ。[Claims for Utility Model Registration] (1) A turn broach in which a plurality of segments 1 are screwed to the outer periphery of a main body 2 of the broach tool with a tightening bolt 4 via a presser piece 3. The segment 1 is provided with an elongated hole 5 or an open slot 10 for attachment and detachment, and the presser piece 3 has a mounting hole 6 with a counterbore portion 6a and a locking portion 7 for the segment 1 connected to each other. It has a long strip shape and is positioned so as to be pushed up by the spring 8 with respect to the long hole 5 or open slot 10 of the segment 1, and is The locking portion 7 secures the attachment/detachment position with respect to the segment 1, and the tightening bolt 4 is inserted through the attachment hole 6 provided with the spring 8 so that its head is located in the counterbore hole 6a of the presser piece 3. A turn broach characterized by being fitted and screwed toward a screw hole 9 of a main body 2 of the tool. (2) In a turn broach in which adjacent segments 1 are simultaneously clamped by tightening bolts 4 via presser pieces 3 on the outer circumference of the main body 2 of the broach tool, on both sides of the segments 1: , a notch step 11 for attachment and detachment is provided, and the presser foot 3 is provided with a mounting hole 6 having a counterbore portion 6a, and locking portions 7 for the notch step 11 in the direction of both ends. The springs 8 are positioned between adjacent segments 1 so that the presser foot 3 is pushed up, and the short side portions can pass through by 90° conversion. The tightening bolt 4 is inserted into the threaded hole 9 of the main body 2 of the tool so that its head is located in the counterbore hole 6a of the presser piece 3, and the spring 8 is wound around it.
A turn broach characterized by being screwed toward.
