In the existing machine tool, the automatic tool change system mainly drives a driven roller group by a hobbing cam in a cam box to drive a tool change arm to generate rotation, and drives the two groups of hobbing cams. The rod group is capable of moving the tool change arm up and down, and when the tool change arm is rotated below a spindle, the action of the cutter or the knife on the spindle is determined by the sensor. When the position of the arm is determined, when the tool change arm reaches the positioning position, the sensor sends a confirmation signal, and the hydraulic cylinder or the air cylinder on the main shaft is actuated, and the hydraulic cylinder or the pneumatic cylinder is touched by a knife.

As for the first operation mode of the present invention, the same operation mode is performed by the synchronous movement, which is an implementation state of the tool changer 14 after the spindle 21 is first loosened. Referring to the first, second, and eighth, 9 is shown, via the control of the main controller 31 of the servo control unit 30, when the servo driver 32 activates the first servo motor 12 to drive the tool change arm 14, the tool change arm 14 will be from FIG. (9a) starting in the counterclockwise direction toward the (9b) direction, the servo actuator 33 simultaneously activates the second servo motor 25 to drive the hitting before the rotating tool change arm 14 approaches the position of the tool 100 on the spindle 21. The cutter unit 20 starts to perform the retraction of the main shaft 21. As shown in (8c) of Fig. 8, when the Cycle time of the motor reaches 41 degrees, the cutter 100 on the main shaft 21 is in a loose state, and the retraction is started slowly.

When the tool change arm 14 has been rotated onto the tool 100 on the spindle 21 and the tool 100 is fastened (see Fig. 2), the servo driver 33 is simultaneously Starting the second servo motor 25 to drive the cutter unit 20 to start the spindle 21 retracting. As shown in (10c) of FIG. 10, when the Cycle time of the motor reaches 60 degrees, the cutter 100 on the spindle 21 starts to retreat. After the knife is retracted (Cycle time is at 100 degrees), as shown in Fig. 10 (10b) and Fig. 9 (9c), the cam box 11 drives the tool change arm 14 downward. Displacement 114mm (Cycle time at 102 degrees), and come to the next starting point (such as 9d in Figure 9; and Cycle time at 158 degrees), continue, as in Figure 9 (9d) and Figure 10 (10a) ) It is shown that the tool change arm 14 is rotated by 180 degrees in the counterclockwise direction and then displaced upward by 114 mm to return to the upper starting point (see 9e in Fig. 9; and the Cycle time is at 277 degrees), at the same time the tool has been completed. Homework, finally, the tool change arm 14 is after the loose knife (the cutter distance is 12 mm), and the angle is rotated clockwise by 65 degrees (as shown in Fig. 9), so that the tool change arm 14 is activated. The spindle 21 is used for the purpose of the simultaneous movement of the loose knife.

As shown in (8b), (8c), 10 (10b), (10c) and 9 (9c), (9e) of Fig. 8, the tool change arm 14 performs a downward displacement of 114 mm. After the upward displacement of 114 mm, there is an angle of 2 degrees of the tooling time (Cycle time), that is, before the upward displacement, the tool change arm 14 first buckles the tool 100 on the main shaft 21, and after the downward displacement, the The tool change arm 14 releases the tool 100 again to prevent the collision.

Next, in Fig. 9, the angle of rotation of the cutter arm 14 and the cutter is an angle of 65 degrees. In practice, it is allowed to be set at an angle of 60 to 90 degrees.
