[0016] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1As shown, the dual-tool magazine tool changing assembly of this utility model includes a machine base 1 and a spindle 11. The machine base 1 is provided with two bases 2, and the two bases 2 are respectively provided with a rotatable first tool disc 21 and a second tool disc 22. A tool changing device is provided between the first tool disc 21 and the second tool disc 22. The first tool disc 21 and the second tool disc 22 are each provided with a number of tool positions for storing tools 23. The spindle 11 can clamp the tools 23 on the first tool disc 21. One of the tool positions on the first tool disc 21 is in an empty state.

[0018] It is understood that the machine tool 1 is also equipped with a multi-axis machining head, and the spindle 11 cooperates with the multi-axis machining head to perform metal processing. During the processing, the spindle 11 needs to use different cutting tools 23 for cutting. Various cutting tools 23 are stored in several tool positions on the first tool turret 21. Among them, one tool position on the first tool turret 21 corresponds to a tool change point. The spindle 11 can move to the tool change point to pick up the cutting tool 23 in the tool position. Of course, the first tool turret 21 can rotate on the base 2 to switch different tool positions and send the cutting tool 23 to the tool change point. Furthermore, the first tool turret 21 has an empty position. If the tool 23 on the second tool turret 22 is needed, the second tool turret 22 will rotate the tool 23 in the corresponding tool position to the side of the empty tool position. Correspondingly, the first tool turret 21 needs to rotate so that the tool position in the control state is close to the second turntable 22. The tool changing device transfers the tool 23 to the empty tool position on the first tool turret 21, and then the first tool turret 21 rotates the tool 23 to the tool changing point and provides it to the spindle.

[0019] Both the first cutter head 21 and the second cutter head 22 are equipped with a plurality of tool holders 24. These tool holders 24 are equidistant from the rotation center of either the first cutter head 21 or the second cutter head 22, and tool positions are located on the tool holders 24. The tool holders 24 are standard modules, each with slots to form tool positions. The tool holders 24 are mounted on the first cutter head 21 and the second cutter head 22 to form a plurality of tool positions around them, used to store various cutting tools. The first cutter head 21 and the second cutter head 22 are rotatable. When the first cutter head 21 rotates, any tool position can be moved to a tool change point. Specifically, the first cutter head 21 has a tool position in a specific control state, used to allow the tool 23 from the second cutter head 22 to be transferred to the first cutter head 21. After machining, the spindle 11 first places the tool 23 on the first cutter head 21, and then moves the tool 23 to the second cutter head 22 for return to its original position via a tool changer.

[0020] Both the first cutter head 21 and the second cutter head 22 are circular. The two bases 2 are spaced apart on the machine base 1, so that the first cutter head 21 and the second cutter head 22 are adjacent to each other. The first cutter head 21 and the second cutter head 22 can rotate independently. Specifically, a rotary motor 25 is provided on the base 2. The rotary motor 25 is connected to the first cutter head 21 or the second cutter head 22 through a gearbox. The rotary motor 25 is a stepper motor. The rotary motor 25 drives the first cutter head 21 to rotate, so that the corresponding tool position moves to the tool change point, or so that the tool position in the control state moves closer to the second cutter head 22. In conjunction with the tool changer, the corresponding tool 23 on the second cutter head 22 is transferred to the first cutter head 21 for later use.

[0021] The tool changing device includes a suspension frame 3 and a tool changing fixture 31. The suspension frame 3 is mounted on the machine base 1 via a lifting device (not shown in the attached diagram). A translational track 32 is provided on the suspension frame 3, with both ends extending to the first tool disc 21 and the second tool disc 22. A tool changing driver 33, which can slide along the translational track 32, is provided on the translational track 32, and the tool changing fixture 31 is mounted on the tool changing driver 33. The tool changing fixture 31 can move between the first tool disc 21 and the second tool disc 22 via the tool changing driver 33, thereby exchanging the tool 23 between the two tool discs to meet machining requirements. The paired arrangement of the two tool discs can shorten the rotation path during tool changing, shorten the tool changing sequence, and improve tool changing efficiency.

[0022] This utility model also includes a controller, which is connected to the rotary motor 25 and the tool changer 33 via wiring. The controller is equipped with a counter. The controller can record the positional relationship between the tool 23 and the tool position through the counter. When idle, the controller controls the tool changer, the first tool disc 21 and the second device to return the tool 23 to its original position.

[0023] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
