As shown in FIGS. 6 to 13 , the steps and processes of performing tool changing operations according to the present invention are explained. As shown in FIG. 6 , the first moving base 22 of the first pick-and-place device 20 is displaced along the Y-axis to the cutter head 11 and corresponds to the position above the tool clamping base 40 . Among them, for the convenience of explanation and viewing of the diagram, only two tool clamping seats 40 are drawn in FIG. 6 , which will be described first.

As shown in FIG. 7 , the Z-axis drive unit 26 drives the first fixed plate 211 to move downward along the Z-axis, and pushes the clamping member 212 against the tool clamping seat 40 to cause the actuating rod 41 to slide relative to the cutterhead 11 . The clamping groove 412 of the actuating rod 41 is dislocated with the latch member 72 so that the outer circumferential surface 411 corresponds to the latch member 72 (the latch member 72 is retracted and retracted), thereby urging the actuating rod 41 of the tool clamping base 40 to face each other. The cutterhead 11 moves downward.

As shown in FIG. 8 , when the tool clamp base 40 is lowered, the preparation tool handle A also drops a certain distance. At this time, the second pick-and-place device 30 moves along the Y-axis and connects the second pick-and-place part 31 to the preparation tool handle A. . When the second pick-and-place part 31 is connected to the preparation tool handle A, the first pick-and-place part 21 is locked on the tool clamping base 40 by the locking groove 212a of the fastener 212 after the displacement of the X-axis and the Y-axis. The rod 41 (the end away from the preparation tool handle A), then the first pick-and-place part 21 pulls the tool clamping base 40 along the Z axis, so that the tool clamping base 40 releases the preparation tool handle A, and releases the tool clamping base 40 after the preparation tool handle A Then it is reset to the original position of the cutter head 11.

As shown in FIG. 9 , when the second pick-and-place part 31 is connected to the preliminary knife handles A, there is at least one vacant knife edge 312 between every two preliminary knife handles A.

As shown in FIG. 10 , when the second pick-and-place part 31 is completely connected to the preparation tool handle A, and then moves along the Y-axis and toward the spindle 3 direction, the vacant knife edge 312 shown in FIG. 9 is connected to the spindle 3 The processing tool handle B.

As shown in FIG. 11 , after the processing tool holder B on the spindle 3 is connected to the second pick-and-place part 31 , the spindle 3 moves along the Z-axis and separates from the processing tool holder B.

As shown in FIG. 12 , following the aforementioned action, the second pick-and-place part 31 moves through the X-axis, so that the second pick-and-place part 31 moves below the spindle 3 so that the spindle 3 can be lowered to connect the preparation tool handle A.

As shown in FIG. 13 , after the aforementioned tool change operation is completed, the spindle 3 returns to its original position, and the second pick-and-place unit 31 returns the processing tool handle B to the cutter head 11. Thus, through the aforementioned operation, the prepared tool handle A originally on the cutter head 11 and the processing tool handle B on the spindle 3 are exchanged. It should be noted that after the second pick-and-place unit 31 carries the processing tool handle B of the spindle 3, it can be returned to the lower part of the cutter head 11, and the vacant tool clamping seat 40 is lowered to connect to the processing tool handle B, so as to send the processing tool handle B to the cutter head 11 for temporary storage, thereby completing the entire tool handle exchange procedure.

According to the aforementioned action description and mechanism principle, the present invention can also be applied to single-axis processing machines to achieve high-efficiency tool changing operations.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, according to the technical solution of the present invention and its Equivalent substitutions or changes of the inventive concept shall be included in the protection scope of the present invention.
