When using such a holder, if a chip becomes damaged and needs to be replaced with a new one, the undamaged chip must be installed and replaced with a different holder. This type of chip exchange method is
Requires considerable space to store the holder. In addition, replacing each holder does not take advantage of the advantages of a throw-away type chip that requires use of multiple corners. Furthermore, replacing each holder has the disadvantage that the rigidity of the holder itself is unstable.

[Summary of the Invention] A lever housed in the holder is swung by the forward and reverse rotation of the drive screw to seat the tip in the recess in a manner that allows it to be tightened and loosened freely, and the tip is pushed out of the recess by a pressing body provided in the recess. This makes it easy to remove chips after one use by biasing them in the direction of separation, and further supplies unused chips onto the pressing body via a guide.

It is pushed upward by al. Then, the air cylinder 67) is activated to advance the push rod c31 in the direction of the arrow by a distance approximately equal to the length of the -side of the chip (6). At this time, since unused chips (6) are loaded in a row in the guide body, one
unused chips (6) are extruded. As a result, the unused chips (6) are pressed by the pressing bodies ■, c! Drop the used chip (6) supported by 1 in the direction of arrow (c),
Instead of this used chip (6), an unused chip (6) is positioned on the pressing body (21). At this time, the operating axis t41 is advanced in the direction of the arrow (to), and the dropped chip The used chips (6) are stored in a collection box. After collecting this used tip (6), the operating shaft @0 is moved back in the direction of arrow 0Q. However, the elevator axis (43 is the arrow (goods))
The lower surface of the unused chip (6) supported by the pressing member (21) is pressed against the seating surface of the security deposit C19 by the contact member (2).At this time, the nut runner (5) also Since it is fitted into the hexagonal hole (C), rotate this nut runner (5) in the opposite direction to the previous direction and raise the drive screw α, thereby swinging the lever αe in the direction of the arrow (C). , insert the unused tip (6) into the recess (14)
Press against the side wall surface of the holder (43) and tighten the holder (with force). When this tightening work is completed, raise the elevating shaft (43) to the original position. Also, move the push rod C31 in the direction of the arrow (toward) to the original position. Then, the unused tip (6) loaded in the tool cartridge (30) is released by the compression spring
)..., the uppermost one is newly replenished to fill the hole of the tip (6) pushed out into the guide body and fastened to the holder (7)K. Thus, when the tip replacement work is completed, the holder (7) to which the unused tip is fastened is
It is positioned at the turning position and the turning operation is resumed.

In this manner, the lathe of this embodiment can quickly and reliably perform automatic tip replacement. Therefore, it is possible to contribute to the promotion of automation and unmanned turning operations, and the operating rate of the device is significantly improved. Furthermore, since it is sufficient to secure enough space to accommodate the chip to be replaced, the space is significantly saved compared to the case where the entire holder is replaced. moreover,
Since there is no need to attach and detach the holder, the rigidity can be increased, and as a result, it is possible to contribute to improvement in processing accuracy.

In the above embodiment, the holder may be provided with a compressed air outlet to remove dust, chips, etc. attached to the tip seating surface.Furthermore, a touch sensor may be provided to detect the position of the cutting edge after tip replacement. A special touch sensor may be provided, and the detection signal from this touch sensor may be fed back to the touch control section. Furthermore, by aligning the unused corners of the used chips once collected and reloading them into the tool cartridge, xa-Away (Throw-Ava
y) All corners of the shape can be used. Furthermore, the attachment and detachment of the tool cartridge may be automated using a robot hand. Furthermore, the shape and number of the pressing body (2) and the compression spring (L!J) may be set arbitrarily.

The lathe of the present invention can quickly and reliably replace the chips on its own. Therefore, it is possible to contribute to the promotion of automation and unmanned turning operations, and the operating rate of the device is significantly improved. Moreover, since it is sufficient to secure a space to accommodate the chip to be replaced, the space is significantly saved compared to the case where the entire holder is replaced. Furthermore, since there is no need to attach and detach the holder, rigidity can be increased, and as a result, processing accuracy is improved.

[Claims] A lathe characterized by having the following configuration. (a) Workpiece holding section that holds and rotates the workpiece. (b) A holder having a through hole at its tip and a recess for holding a tip for cutting the workpiece, a tool rest from which the holder protrudes, and one end of the holder at the recess forming part. protrudes into one end of which the chip is inserted through the through hole, and further includes a lever that is swingably installed in the holder and a locking portion to which the other end of the lever is locked. a drive screw which is screwed onto the holder and which allows the tip to be seated in the recess in a manner that allows it to be tightened and loosened by swinging a lever that is locked in the locking portion by rotating the drive screw forward and backward; and a pressing body that is elastically supported at the bottom of the recess and urges the chip seated in the recess in a direction to leave the recess, and is provided so as to be freely positionable to the chip exchange position of the holder. tool holder. (c) a guide body that accommodates the chip to be seated in the recess and guides it onto the press body positioned at the chip exchange position; and an extrusion mechanism that pushes out the chip in the guide body toward the press body. and a chip supply body that supplies the chips to the guide body, and a chip supply body that is provided so as to be able to move forward and backward with respect to the holder positioned at the chip exchange position, and that presses the chips, which are urged by the pressing body, into the recess. A tip exchange unit comprising a pressurizing body attached to the tip and a tip attachment/detachment mechanism having a nut runner that rotationally drives the drive screw.
