It should be noted that, when each first slot 32 is engaged with a first tool holder 33, each first tool holder 33 must be disposed adjacent to a first slot 32, and the opening 331 and the first slot The holes 32 cooperate to accommodate the in and out of the cutter 242; similarly, each outer ring holder 34 is disposed adjacent the outer edge 312 such that the opening 341 is unobstructed underneath and can accommodate the ingress and egress of the cutter 242.

The above is an overview of the shape of each component of the bucket type tool magazine and the machining center machine for multi-processing head synchronous tool change according to the present invention; then, the action of the present invention and the expected effect can be stated as follows: When the user wants to perform the tool changing operation using the present invention, the two sets of processing heads 241 are first moved along the X axis to a position above the bucket type magazine 3, so that one of the processing heads 241 is just aligned with the disk shaped body 31. An outer ring holder 34 located in the X-axis direction, and the other processing head 241 is just aligned with a first tool holder 33 located on the other side of the disc-shaped body 31, so that when the two sets of processing heads 241 are lowered in height, The opening 331 of the first tool holder 33 cooperates with the first slot 32 to accommodate the in and out of the cutter 242, and the bottom of the opening 341 of the outer ring holder 34 is unobstructed, so that the two sets of processing heads 241 are in the outer ring. The tool holder 242 is simultaneously replaced by the tool holder 34 and the first tool holder 33, thereby achieving the effect of synchronous tool change. When the next synchronous tool change is to be performed, as long as the rotary shaft 301 is rotated by an angle until the next designated outer ring tool holder 34 comes to the X-axis direction, the two sets of machining heads 241 can perform the next synchronous tool change.

In summary, the bucket cutter magazine and the machining center machine of the present invention are suitable for the multi-machining head synchronous tool change and the machining center machine thereof are mainly for solving the problem of the tool change of the machining center machine 10 having a plurality of sets of processing heads, and the technical means adopted by the same. The plurality of first slots 32 are opened in the cutter head 30, and the cutters 30 are circumferentially arranged in a plurality of outer ring holders 34 and the first holders 33, and the outer ring holders 34 and the first holders are arranged. The tool 242 is placed in the 33, and when the plurality of machining heads 241 are moved to the cutter head 30, the tool change point is located at the position of the outer ring holder 34 and the first tool holder 33, and the opening of the first tool holder 33 The 331 cooperates with the first slot 32 to accommodate the ingress and egress of the cutter 242, and the underside of the opening 341 of the outer ring holder 34 is unobstructed; thus, the plurality of processing heads 241 can perform the tool change operation simultaneously, thereby improving the tool change efficiency. .

Referring to Figures 6-8, a second preferred embodiment of the bucket magazine for multi-processing head synchronous tool change is described, which is mounted on a machining center machine; the machine unit 20 of the machining center machine has only one slip The Z-axis head block 24 disposed on the lateral slide rail 231 has three processing heads 241 movable up and down in the Z-axis direction on the Z-axis headstock 24, and the present invention is applicable to the bucket cutter of the multi-machining head synchronous tool changer. The main difference between the second preferred embodiment of the library and the first preferred embodiment is that the cutter head 30 has a second slot 35 which is disposed on the disk-shaped body 31 at a plurality of intervals and equidistant from the rotating shaft 301. And a plurality of second tool holders 36 of the disk-shaped body 301, wherein each of the second slots 35 is fitted with a second tool holder 36, and the number of the second slots 35 is the same as the number of the first slots 34. And each of the first tool holders 33 corresponds to a second tool holder 36 in the radial direction. Each outer ring holder 34 has an opening 341 for a tool 242 to enter and exit away from the axis of rotation 301. Each of the first holders 33 has an opening 331 for a tool 242 to enter and exit away from the axis of rotation 301, each The second tool holder 36 has an opening 361 for a cutter 242 to enter and exit in a direction away from the rotation shaft 301. This configuration allows the three sets of machining heads 241 to perform synchronous tool change operations.

The opening 341 of the outer ring holder 34, the opening 331 of the first holder 33, and the opening 361 of the second holder 36 of the embodiment are all openings away from the rotation axis 301, that is, the three-knife opening on the same diameter. All of them are oriented in the same direction, and such a design is more suitable for a short distance between the plurality of processing heads 241. For example, three processing heads 241 that can move up and down in the Z-axis direction are disposed on a Z-axis headstock 24. In contrast, in the first preferred embodiment, the opening 341 of the outer ring holder 34 is oriented away from the rotating shaft 301, but the opening 331 of the first holder 33 is directed toward the rotating shaft 301, which is more suitable. A design for a long distance between the plurality of processing heads 241, for example, two processing heads 241 movable up and down in the Z-axis direction are respectively disposed on the two Z-axis head holders 24.

It should be noted that the above description is only a suitable situation, but is not limited.

Referring to FIG. 8, when the user wants to use the present invention to perform a tool change operation, first, the three sets of processing heads 241 are moved along the X axis to a position above the bucket magazine 3, so that one of the processing heads 241 is just aligned on the disk. The outer body 31 is located on an outer ring holder 34 in the X-axis direction, and the other processing head 241 is just aligned with a first tool holder 33 located on the same side of the disk-shaped body 31, and the other processing head 241 is just aligned on the disk. a second tool holder 36 on the same side of the body 31, when the three sets of processing heads 241 are lowered in height, the opening 331 of the first tool holder 33 cooperates with the first slot 32 to accommodate the in and out of the cutter 242. The opening 361 of the second tool holder 36 cooperates with the second slot 35 to accommodate the in and out of the cutter 242, and the bottom of the opening 341 of the outer ring holder 34 is unobstructed, so that the three sets of processing heads 241 can be placed on the outer ring holder. 34. The first tool holder 33 and the second tool holder 36 simultaneously perform the work of replacing the tool 242, thereby achieving the effect of synchronous tool change. When the next synchronous tool change is to be performed, as long as the rotary shaft 301 is rotated by an angle until the next designated outer ring tool holder 34 comes to the X-axis direction, the three sets of machining heads 241 can perform the next synchronous tool change.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change and modification according to the scope of the present invention and the description of the invention.
