<Embodiment> Hereinafter, an embodiment of the turret device according to the present invention will be described in detail with reference to FIGS. 1 to 3.

In this turret device, as shown in FIG. 1, an octagonal turret 2 is placed on a front surface 1a of a table 1, and a cylindrical rotary shaft 3 for a table is formed on the table 1 so as to penetrate the front and back surfaces thereof. The rotating shaft 3 is attached to the table 1
Is configured to be indexed and rotated.

On the other hand, the turret 2 is opening 4 in the indexing rotation center O ₁ part
The inner wall of the opening 4 is provided with an inner flange 5, and such a turret 2 is provided with four bolt through holes 6, 6,... Provided in the inner flange 5 (see FIG. 2). , And are detachably attached to the surface of the table 1 via bolts 7, 7,....

A tool spindle 8 is rotatably disposed on the inner peripheral surface side of the table rotation shaft 3.
Faces the opening 4 and has a drive gear 9 attached thereto.

By the way, the turret 2 is attached to the table 1 as described above. Next, a portion for finely adjusting the attachment position of the turret 2 will be described.

An eccentric storage hole 10 is formed in the surface 1 a of the table 1. The eccentric ring 11 of the eccentric pin 11 is formed in the eccentric storage hole 10.
a is stored in a rotatable manner, while the turret 2
A main shaft insertion hole 12 having a long hole shape is formed (see FIG. 2). The main shaft insertion hole 12 is formed through the front and back surfaces of the turret 2 and the main shaft 11b of the eccentric pin 11 is inserted. It is configured to be.

As shown in FIG.
Number of the tool attachment hole 13, 13 is provided, along with being drilled toward the indexing rotation center O ₁ of the turret 2 from the outer peripheral surface of the respective tool mounting holes 13, 13 are turret 2, The openings 4 are formed to have the same dimensions and communicate with the opening 4.

A fixed tool such as a tool or a shaver, or a rotary tool such as a drill is attached to each of the tool mounting holes 13, 13... For example, the attachment structure of the tool is attached to one end of a holder 15 that supports the tool 14. A shaft portion 16 is provided, the shaft portion 16 is formed so as to be insertable into the tool mounting hole 13, and after the shaft portion 16 is inserted into the tool mounting hole 13, it is configured to be fixed with a screw 17. .

On the other hand, as shown in FIG.
The rotating shaft exterior part 18 of 18 is formed so as to be insertable into the tool mounting hole 13, and is configured to be fitted with the screw 20 after the rotating shaft exterior part 19 is inserted into the tool mounting hole 13. .

By the way, the drill 18 is mounted as described above. At this time, the driven gear 22 attached to the rotation shaft 21 of the drill 18 is used.
Are engaged with the drive gear 9, whereby the rotary shaft 21 and the tool spindle 8 are engaged with each other and are interlocked with each other.

The positioning pins 23 are used for positioning the indexing rotating table.

Next, the operation of the turret configured as described above will be described with reference to FIGS.

According to this turret device, the turret 2 is removed from the surface of the table 1 by inserting a tool through the opening 4 of the turret 2 and loosening and removing the bolt 7 (see FIG. 3).

On the other hand, when attaching the turret 2 removed as described above to the surface of the table 1, the spindle 11 b of the eccentric pin 11 is inserted into the spindle insertion hole 12, and the turret 2 is placed on the surface of the table 1. Insert a tool into the turning hole 11c from 12 and turn the main shaft 11b.

As a result, the eccentric wheel 10a rotates with the eccentric wheel storage hole 10 as a reference. As a result, the main shaft 11b moves right and left in an arc, and the turret 2 turns by pressing the inside of the main shaft insertion hole 12. After finely adjusting the mounting position of the turret 2 in this way, the turret 2 is fixed to the surface of the table 1 with the bolt 7.

The tool 14 or the drill 18 is replaced while the turret 2 is removed as described above. The tool 14 is replaced by loosening the screw 17 and removing the screw 17, thereby removing the shaft 16 together. Replace with a new one.

The turret in which the cutting tool or the drill is exchanged as described above is set using a dial gauge or the like before being attached to the table.

Therefore, according to the above embodiment, when the turret is mounted on the table surface, if the eccentric pin of the eccentric pin is turned with reference to the eccentric ring storage hole, the main axis of the eccentric pin turns left and right in an arc, and the main shaft is inserted. Since the turret pivots by pressing the hole, the mounting position of the turret can be finely adjusted.

In this embodiment, since eight tool mounting holes are formed in the same size, the mounting position of the fixed tool can be arbitrarily selected.

Moreover, in this embodiment, the above-mentioned tool mounting holes communicate with the opening, and the rotary shaft for the tool faces the opening. Can be arbitrarily selected.

In addition, according to the above embodiment, since the inner flange formed on the inner wall of the opening and the table surface are fixed with bolts, it is easy to insert a tool into the opening, loosen the bolt and remove it. The turret can be removed from the table.

<Effect of the Invention> As described above, the turret device of the machine tool according to the present invention has the eccentric ring storage hole formed in the table surface and the spindle insertion hole formed in the turret. By rotating the eccentric ring of the eccentric pin with reference to the eccentric ring storage hole, the main shaft of the eccentric pin turns left and right in an arc, and presses the main shaft insertion hole to turn the turret. Can be finely adjusted, and the mounting workability is improved.

In the invention according to the second aspect, since the plurality of tool mounting holes are formed to have the same size, the mounting position of the tool can be arbitrarily selected, and the usability is good.

In the device according to the third aspect, each of the tool mounting holes communicates with the opening, and one end of the rotary shaft for the tool faces. Therefore, when the rotary tool is attached, not to mention the fixed tool as described above. However, the mounting position of the rotary tool can be arbitrarily selected, which is very convenient.
