A clamp tool for clamping and fixing an indexable tip with a hole to a chip seat having a recessed side wall provided at the tip of a tool holder is already known from Japanese Patent Laid-Open No. 47-40379.

The publication states that a compression spring is pressed from the side against a suppression shaft that is pulled by a connector through a screw, and a strip ring that fixes the chip shim is also restrained from rapid movement, thereby securing the chip securely. Let it rest,
A method is described in which the chip is pressed against the side wall by pulling the connector with the conical part of the towing bolt and tilting the suppression shaft.

The shaft body 3 is inserted through the through hole 2 of the tip 1, the through hole 23 of the pad 22, the through hole 20 of the connector 4, and the through hole 24 provided through the tool holder 7. A nut 34 having a spherical bottom surface 27 and a lock nut 26 are screwed to the end of the shaft body 3 to open the through hole 2 of the pad 22.
The pad 22, the connector 4, and the tool holder 7 are joined together by pressing together with the collar 28 of the shaft body 3 in the shaft body 3.

The crank bit of the present invention has the above-mentioned configuration, and when the traction bolt 5, which has oppositely threaded portions at both ends, is rotated clockwise, the wedge-shaped nut 31 descends along the slope 12 of the connector. The connector 4 is forced toward the shank B side under the resistance of the compression spring 19, and the front circumferential surface 32 of the through hole 20 of the connector is threaded in opposite directions at both ends of the shaft body 3. By pressing in the direction of the traction bolt 5 and tilting the shaft 3, the tip 1 is pressed against the side wall 29 of the cutting tool holder 7 by its head 30 as shown in FIG. 1 and fixed.

In this state, there are many contact areas between the connector 4 and the wedge-shaped nut 31 due to the slope, so the tightening part does not loosen due to resistance or impact during cutting, and the shaft body does not move due to the impact action of the compression spring when tightening. It is possible to always perform reliable tightening without causing any impact.

In addition, since a compression spring is applied to the back of the rising part of the connector, the empty space for accommodating the spring is given an upper position relative to the tool holder, and a hole is drilled deep inside the tool holder to accommodate the spring. Because I have nothing to do,
It does not reduce the rigidity of the tool holder, making it easy to replace the tip, and also fixes the tip while suppressing sudden traction force from being applied to the shaft due to the resistance of the compression spring when tightening the double screw. , which provides a reliable tightening effect.
