Referring to FIG. 22 , the operation of separating the tool T from the tool port 80 is performed at the standby point Y of the tool port 80 .

This is to allow the tool (T) mounted on the main shaft to be exchanged with the tool (T) coupled to the tool port (80) while the tool port exchange unit (50) rotates 180 degrees.

Looking at the operation method, when hydraulic pressure is supplied to the release cylinder 250 , the tool port pusher 240 in which the pusher groove 241 is formed pushes the center beam 87 of the tool port 80 .

Accordingly, the beam extension portion 87a formed at the front end of the center beam 87 is pushed outward of the tool coupling portion 83, and the second detachable portion T2 of the tool T is connected to the tool coupling portion ( 83) is pushed outward.

And at the same time, as the beam extension portion 87a moves outward, the tool port ball 83b moves adjacent to the inside of the center port 85 , that is, the center beam 87 . In this operation, the fixing of the first detachable part T1 of the tool T is released, and thereafter, the first, second, and third detachable parts T1, T2, T3 of the tool T are connected to the tool port ( 80) is in a state that can be gently separated from the tool coupling portion (83).

Thereafter, the tool port exchange unit 50 is rotated 180 degrees to exchange the tool (T).

When the tool (T) replacement by the tool port exchange unit (50) is completed, the center beam (87) can be returned to its original position by the tool port spring (86).

On the other hand, FIG. 13 is a perspective view showing a state in which the toolport clamping unit 200 clamps the toolport 80 in the present invention, and FIG. 14 is the toolport clamping unit 200 in the present invention. It is a plan view showing a clamped state, and FIG. 15 is a plan view showing a state for fixing the tool port 80 by the gripper 220 in the invention disclosed in FIG. 14 .

16 is an operation state diagram showing a state of transporting or conveying the toolport 80 between the magazine origin (X), the third origin (Z), and the toolport standby point (Y), and FIG. 17 is the toolport transport in the present invention. The unit 300 is a side cross-sectional view showing a state in which the tool port 80 is fixed.

When explaining the operation method of the present invention according to the above-described structure, first referring to FIG. 13 , it can be seen that a heavy tool is mounted on the magazine 20 in the tool port 80 . The heavy-duty tool shape is expressed as an example, and may have a different shape.

Referring to FIG. 16 , the position of the toll port mounted on the magazine 20 may be defined as the magazine origin (X).

The tool port clamping unit 200 firmly fixes the tool port 80 in order to call the required heavy-duty tool to the magazine origin (X) position, and to transfer the heavy-weight tool to the tool port exchange unit 50 . 14 and 15 , while a pair of gripper arms 221 are inserted into the first tool port groove of the tool port 80 , both sides of the tool port 80 are held and fixed.

And the toolport clamping unit 200 is coupled to the toolport transfer unit 300 at the third origin (Z) while moving along the first linear guide (426). At this time, the gripper 220 fixing the tool port 80 is inserted into the receiving portion 370 of the tool port transfer unit 300 .

Referring to FIG. 16 , after the toolport 80 fixed by the gripper 220 is transferred from the magazine origin X to the third origin Z, the state of moving to the inside of the receiving part 370 is confirmed. can

The tool port 80 inserted into the accommodating part 370 is a tool while the clamping pin 350 is inserted into the second tool port groove 82 of the tool port 80 according to the extension of the rod end of the first cylinder 330 . The port 80 is firmly fixed on three sides. In this way, it is possible to stably transport a heavy tool by firmly supporting it through three-sided fixing.

And as the rod end of the second cylinder 340 rises for the movement of the toolport transfer unit 300 , the positioning pin 380 is separated from the insertion groove 425b of the fixing block 425 . Accordingly, the toolport transfer unit 300 can move along the second linear guide 427 .

Thereafter, the ball screw 421 is rotated by the drive of the servo motor 424, and the tool port clamping unit 200 and the tool port transfer unit 300 are together at the tool port waiting point Y along the first and second linear guides. ) will be moved to

After moving to the tool port standby point (Y), the rod of the first cylinder 330 is raised again to release the clamping pin 350 from the second tool port groove 82 of the tool port 80 .

Then, by extending the rod of the second cylinder 340, the position fixing pin 380 is inserted into the insertion groove 425b of the fixing block 425 so that the tool port transfer unit 300 is fixed.

Thereafter, as described above, by operating the release cylinder 250, the tool port pusher 240 pushes the center beam 87 of the tool port 80 to perform the operation described in FIGS. 21 and 22 , so that the tool (T) is in a state that can be separated from the tool port (80).

Next, when the rotary motor 55 is driven, the rotary body 51 rotates at intervals of 90 degrees around the drive shaft 55a, and the tool port 80 of the main shaft 60 and the accommodating part of the tool port transfer unit 300 Replace toolport (80) at (370).

According to the present invention, through the structure and operation method as described above, in particular, the tool port 80 is fixed on both sides of the tool port 80 through the gripper 220 and the upper side of the tool port 80 is fixed through the clamping pin 350 . ), through the shortest transport structure between the magazine origin (X) and the tool port standby point (Y) through the first and second linear guides (426, 427), the tool port exchange unit (50) even for heavy tools stably can be moved to the corresponding position. This can expand the tool weight range of the main shaft 60, enabling more diverse machining operations.

The above is merely showing a specific embodiment of a machine tool having a tool port transfer device capable of applying a heavy tool.

Therefore, within the limits that do not depart from the spirit of the present invention described in the following claims, the present invention can be substituted and modified in various forms, so that those of ordinary skill in the art can easily grasp that do.
