を調整するように構成されていた。 In this type of stub holder, a tool stopper for adjusting the position of the tip of a tool such as a drill fixed by a chuck is installed in the tool stopper interior hole of the holder body. In conventional tool stoppers, a guide pin is press-fitted into a diametrical through hole provided in the stopper body, and a pair of axial slits into which both ends of the guide pin loosely fit are provided in the holder body. A screw body for receiving the inner end of the stopper body is screwed into a through screw hole of the holder body, and the receiving position of the stopper body is adjusted by changing the position of the screw body. was configured to do so.

の円滑な移動を妨げる原因となる。 On the other hand, the tool stopper may be provided with a tool holding slit in the tool inner end receiving part of the stopper body. There may be cases where the slit sizes do not match. In such cases, it is desirable to be able to easily replace the stopper body with another stopper body equipped with a suitable tool holding slit, but in the conventional tool stopper configuration as described above, the guide pin press-fitted into the stopper body is Since the holder cannot be easily removed, the holder body must be replaced together with the tool stopper, resulting in very high replacement costs. Moreover, the axial slit provided in the holder body allows foreign matter to enter the holder body, which may hinder smooth position adjustment of the adjustment screw body and smooth movement of the stopper body.

can be used in the following manner for a rotating main shaft 1 provided with a keyway 18 as shown in FIG. That is, the key 16 is fitted into the key fitting recess 17 of the stopper main body 8, and the holder main stopper 4 with the pin 19 fitted into the pin hole 20 of the presser board 12 is inserted into the holder main body. The stop portion 7 and the locked portion 21 of the holder main body 6 are engaged with each other as described above, and the stub holder 3 with the tool attachment chuck 5 and the tool stopper 29 removed is attached to the pin. 19 and key 1
6 is inserted into the shaft hole 2 of the rotating main shaft 1 in a state where it fits into the keyway 18. Then, with the flange portion 22 of the holder main body 6 in contact with the end surface 1a of the rotating main shaft 1 and the rotation stopper locking piece 23 fitted into the end of the keyway 18 opening on the rotating main shaft end surface 1a, the holder main body 6 Using the internal hole 30 of the tool stopper and its bottom through hole 38, insert a bolt operation tool such as a hex wrench or screwdriver with a shaft foot of the required length into the holder main body stopper 4, and insert the tool into the holder body retainer 4. The tool rotates the bolt 13 in the tightening direction while the bolt 13 is fitted into a square hole or the like provided in the head 13a of the bolt 13.

The outer end slit 34 of No. 1 is engaged with the outer end slit 34 of No. 1. At this time, the bolt 33 of the tool stopper 29 is inserted into the through hole 38 of the tool stopper internal hole bottom 30a so that the amount of protrusion of the tool 41 is a predetermined dimension. The stopper main body 31, which is prevented from rotating by the engagement between the inner end of the fixing screw 36 and the keyway 35, is moved in and out of the bolt 33 by rotating it using a hexagonal hole etc. provided in the head 33a of the bolt 33. I can do it. When the amount of protrusion of the tool 41 has been adjusted, the fixing screw 36 is further tightened to fix the stopper body 31 to the holder body 6, and the tightening nut 40 of the chuck 5 is tightened to attach the tool 41 to the holder body 6. Fixed to.

Insert so as to fit into the locking part 7 of the stopper 4. At this time, the locking piece 2
3 is located at a position offset in the circumferential direction with respect to the open end of the keyway 18, and in a state where it is retracted together with the operating ring 25 against the spring 28, the rotating main shaft end surface 1a
is in contact with. Next, the holder main body 6 is rotated using the operating ring 25 in a set direction in which the inner end locked portion 21 engages with the locking portion 7 of the retainer 4. As a result, the locked portion 21 of the holder main body 6 and the locking portion 7 of the retainer 4 are completely engaged, and the rotation locking piece 23 is opposed to the end of the keyway 18, and the spring 28 The locking piece 23, which moves forward with the restoring force, automatically fits into the end of the keyway 18, and the holder main body 6 is locked.

ルク伝達系を経由しても回転力を伝達される。 The tool 41 attached to the rotating main shaft 1 via the stub holder 3 as described above is driven in a predetermined direction by the rotation of the rotating main shaft 1. The holder body 6 is rotated in the reset direction relative to the holder body 6. The rotational force of the rotating main shaft 1 is as follows: rotating main shaft 1→key 16→
Stopper body 8 → locking part 7 → locked part 21 → holder body 6 → chuck 5 → torque transmission system leading to tool 41, rotation main shaft 1 → rotation stopper locking piece 23
The torque is transmitted to the tool 41 via a torque transmission system that extends from → holder body 6 → chuck 5 → tool 41.
The rotational force is also transmitted from the holder body 6 to the tool 41 via a torque transmission system from the holder body 6 to the tool stopper fixing screw 36 to the stopper body 31 to the slit 34 to the tool 41.

は甚大である。 According to the stub holder of the present invention, the tool stopper can be easily pulled out from the tool stopper internal hole of the holder body by simply loosening the fixing screw and pulling it out from the keyway of the stopper body. Therefore, it is possible to easily replace the tool stopper with a stopper body that is adapted to a tool that uses only the stopper body, while leaving the holder body as it is, in other words, it can be easily replaced with a stopper body that is equipped with a tool holding slit of a different size, and this has a tremendous economical effect. It is.

The smooth movement of the adjusting screw shaft and the stopper body is not hindered by foreign matter that has entered.
