る。Since the round piece chip holder according to claim 1 of the present invention has the above-mentioned structure, when the round piece chip is held, the chip pressing portion of the clamper becomes the component force generating portion on the round piece chip side. When abutting force is applied to the round piece chip side by abutting, the chip holding force is divided by the component force generating part into the pushing force in the chip mounting part direction and the pushing force in the chip receiving part direction. It is pressed against the chip mounting part by the pressing force in the part direction and firmly held.

Even if foreign matter such as chips is sandwiched between the chip pressing portion of the clamper and the component force generating portion of the spacer, cracking or chipping of the round piece chip can be prevented, and the invention can be achieved according to claim 3 of the present invention. In the related round piece chip holder, the clamper reliably holds the chips without delaying the outflow of chips during processing.

る。Furthermore, since the round piece chip holder according to claim 4 of the present invention has the above-mentioned structure, the number of parts can be reduced and it is necessary to provide a center hole in the round piece chip as in the conventional case. Since it does not exist, the small-diameter round piece chip can be held without any trouble, and as a result, it contributes to the realization of the small-diameter round piece chip. In addition, like the round piece chip holder according to claim 1, Since the round piece chip is pressed against the chip receiving portion of the holder body by the pressing force in the direction of the chip receiving portion, the positioning accuracy of the cutting edge before and after the rotation of the round piece chip is determined only by the roundness of the round piece chip. As a result, more stable dimensional accuracy than the conventional one can be obtained, and the round piece chip holder according to claim 5 of the present invention is similar to the round piece chip holder according to claim 3 during processing. Without hindering the outflow of kicking chips, so that the pinching by the clamper is reliably performed.

ととなる。Furthermore, since the round piece chip holder according to claim 6 of the present invention is configured as described above, the contact area between the chip pressing slope portion of the clamper and the hemispherical component force generating portion is small. As a result, the possibility that foreign matter such as chips will be caught when holding the round piece chip becomes extremely small, and the round piece chip holder according to claim 7 of the present invention has an obstacle to the outflow of chips during processing. The holding by the clamper will be carried out more reliably without bringing it.

ととなる。In this round piece chip holder 1, when the round piece chip 3 is held, the chip pressing slope 5a of the clamper 5 is placed on the part closer to the work W than the shaft center of the hemispherical component force generating portion 7A of the spacer 7. Abut and clamp bolt 4
When the chip holding force F is applied to the round piece chip 3 side by rotating in the direction of tightening, the chip holding force F is pushed by the hemispherical component force generating unit 7A to the chip mounting unit direction pressing force Fa and the chip receiving unit direction pressing force. It is divided into pressure Fb, and at this time, the spacer 7
Since the round piece chip 3 and the round piece chip 3 are in surface contact with each other, the pressing force Fa in the chip mounting portion direction is transmitted to the round piece chip 3 as a distributed load, and the round piece chip 3 is mounted by the pressing force Fa in the chip mounting portion direction. It is pressed against the placing portion 2a and firmly held.

れることとなる。Also in the round piece tip holder 11 of this embodiment, the tip pressing protrusion 15a of the clamper 15 is brought into contact with the conical surface of the spacer 17 on the workpiece W side with respect to the shaft center of the truncated cone-shaped component force generating portion 17A. Then, when the clamp bolt 4 is rotated in the tightening direction, as shown in FIG. 2 (c), the tip holding force F is applied to the tip mounting portion direction pressing force Fa and the tip receiving force Fa by the truncated cone-shaped component force generating portion 17A. It is divided into the pressing force Fb in the part direction. At this time, since the spacer 17 and the round piece chip 3 are in surface contact with each other, the round piece chip 3 is pressed by the chip mounting part direction pushing force Fa transmitted as a distributed load.
It is pressed against the chip mounting part 2a and firmly held, and at this time, the contact area between the chip pressing protrusion 15a of the clamper 15 and the conical surface of the truncated cone-shaped component force generating part 17A is extremely small. It is extremely unlikely that foreign matter such as chips will be caught in the chip. Even if chips are sandwiched between the chip pressing projection 15a of the clamper 15 and the truncated cone-shaped component force generating section 17A of the spacer 17, even if chips are caught in the chip mounting direction. Pressing force F
Since a is not concentrated on one point of the round piece chip 3, the round piece chip 3 is held without being cracked or chipped.
