[0031] The exemplary embodiments of the present application are described in detail below with reference to the accompanying drawings, and the technical principles of the present application are not intended to be limited to the specific disclosed embodiments, but the scope of the present application is limited only by the patent claims, covering alternatives, modifications and equivalents.

[0032] Various modifications and further improvements to the technical features described herein and any other applications of the principles of the present application can be made by those skilled in the relevant art. Such modifications and applications should be considered within the scope of the present application. In addition, some parts of the constituent parts are omitted in some of the drawings for the sake of readability, or are depicted using phantom lines and the like.

[0033] Referring to Figures 1 to 10 Fig. 1, a machining tool magazine system 100 of the present application is shown, which is provided in a machining tool 1 having a worktable 2 and a spindle 3. The machining tool 1 can be a single-spindle machining tool or a multi-spindle machining tool, and if it is a multi-spindle machining tool, it has a plurality of spindles 3. The worktable 2 is provided on a machine base 4 of the machining tool 1, and the machine base 4 is provided with a column 5, and the spindle 3 is provided in the column 5 and is movable along the Z axis. The machining tool 1 is provided with a frame 6 on the opposite side of the column 5. The machining tool magazine system 100 includes a tool storage device 7 and a tool exchange device 8.

[0034] The tool storage device 7 is located on the front side of the spindle 3 and above the machine base 4 and the worktable 2. The tool storage device 7 has a plurality of tool carrying units 10 arranged side by side along the Y axis, and each tool carrying unit 10 has a lifting bracket 11 and a clamp seat 12 positioned in the lifting bracket 11. The lifting bracket 11 is capable of lifting and displacing along the Z axis and switching between a tool storage position P1 (as shown in Figure 2 ) and a tool exchange preparation position P2 (as shown in Figure 6 ). Figures 1 to 5

[0035] As shown in Figure 1 and Figure 3 ​As shown, in this embodiment of the invention, the tool storage device 7 further includes a fixed base 20, a drive unit 30, and multiple Z-axis lifting units 40. The fixed base 20 is disposed on the top of the column 5 of the machining machine 1 and extends towards the front of the machining machine 1. The drive unit 30 has a drive source 31 and a connected drive shaft 32. The drive source 31 is a motor, and the drive shaft 32 is connected to the motor and mounted on the fixed base 20. The multiple Z-axis lifting units 40 are disposed at the tool storage position P1 and are respectively connected to the drive shaft 32 and each lifting frame 11, that is, the Z-axis lifting units 40 and the drive shaft 32 are disposed on the fixed base 20.

[0036] Each Z-axis lifting unit 40 has a drive gear 41, a clutch 42, and a rack 43. The drive gear 41 and the clutch 42 are coaxially connected to the drive shaft 32. The drive gear 41 meshes with the rack 43, which extends through the fixed base 20 and is connected to the lifting frame 11. The clutch 42 can be controlled to engage or disengage with the drive gear 41. When the clutch 42 is disengaged from the drive gear 41, the drive gear 41 is not driven by the drive shaft 32. When the clutch 42 is engaged with the drive gear 41, the drive gear 41 can be driven to rotate by the drive shaft 32. Thus, when the clutch 42 is connected to the drive gear 41 and can be driven by the drive shaft 32, the drive gear 41 drives the rack 43 to move along the Z-axis, causing the lifting frame 11 and the tool holder 12 to move to... Figure 6 The tool change preparation position is P2.

[0037] like Figure 3 and Figure 4 and cooperate Figure 2 and Figure 6 As shown, the fixed base 20 has a limiting unit 21 on one side of each Z-axis lifting unit 40 to selectively limit the height of the rack 43, so that the lifting frame 11 is held in the tool storage position P1 or in the tool change preparation position P2. The limiting unit 21 has a limiting rod 211 and a pneumatic cylinder 212 for driving the limiting rod 211. The rack 43 has multiple limiting holes 431 on one side, which are arranged longitudinally on the rack 43. There are three limiting holes 431 to allow the corresponding limiting rods 211 to be inserted to limit the height position of the rack 43. For example, when the limit rod 211 is inserted into the limit hole 431 at the highest position, it means that the lifting frame 11 is in the tool changing preparation position P2; when the limit rod 211 is inserted into the limit hole 431 at the lowest position, it means that the lifting frame 11 is in the tool storage position P1; when the limit rod 211 is inserted into the limit hole 431 at the middle position, the lifting frame 11 is in the maintenance position for inspection and maintenance.

[0038] In addition, the Z-axis lifting unit 40 has guide rods 44 on both sides of the drive gear 41. The guide rods 44 slide through the fixed base 20 and are connected to the opposite lifting frame 11 to ensure the stability of the lifting frame 11 when it is raised or lowered.

[0039] As shown in Figure 5 The two sides of the bracket 11 are each provided with a side rod 111 having a transverse groove 112. The clamp seat 12 has a positioning block 122 corresponding to the side rod 111, and a portion of the positioning block 122 is capable of being in relative sliding with the transverse groove 112 along the Y axis. In the embodiment of the present application, the positioning block 122 and the side rod 111 have a positioning member 113 therebetween, and the positioning member 113 is capable of moving relative to the Z axis to make the positioning block 122 and the side rod 111 have a positioning relationship. The positioning member 113 is arranged on the side rod 111, and the end of the positioning member 113 has an elastically expandable bead 1131, which is capable of protruding or not protruding into the transverse groove 112, and the top of the positioning block 122 is provided with a recess 1221 corresponding to the bead 1131. When the positioning block 122 is arranged in the transverse groove 112, the bead 1131 protrudes into the transverse groove 112 and is positioned in the recess 1221, so that the positioning block 122 and the side rod 111 form a positioning state. In addition, the bottom of the positioning block 122 has a linking hole 1222.

[0040] The tool exchange device 8 is capable of making the clamp seat 12 disengage from the bracket 11 at the tool changing preparation position P2 and return, so as to drive the clamp seat 12 to move along the Y axis to the tool changing position P3, so that the spindle 3 is taken off or put back on the tool handle A.

[0041] As shown in Figure 5 and Figure 6 The tool exchange device 8 includes a sliding seat 50, a pushing member 60, a Y axis driving unit 70 and an X axis driving unit 80. The pushing member 60 is arranged on the sliding seat 50, the Y axis driving unit 70 is arranged between the column 5 and the frame 6, and is used to drive the sliding seat 50 to move along the Y axis, and the X axis driving unit 80 is arranged between the sliding seat 50 and the pushing member 60, and is used to drive the pushing member 60 to move along the X axis relative to the sliding seat 50. The two sides of the pushing member 60 correspond to the linking holes 1222 of the positioning blocks 122 of the clamp seat 12, and have linking columns 61, which are used to make the linking holes 1222 and the linking columns 61 engage with each other when the bracket 11 moves to the tool changing preparation position P2. The Y axis driving unit 70 includes sliding rails, sliding blocks, a motor and a rack, the rack is arranged between the frame 6 and the column 5, the motor is engaged with the rack through a gear, and the sliding seat 50 is driven by the motor to move along the Y axis through the cooperation of the sliding rails and the sliding blocks. The X axis driving unit 80 includes sliding rails, sliding blocks, a motor and a screw rod, and the sliding rails and the sliding blocks of the X axis driving unit 80 are arranged between the pushing member 60 and the sliding seat 50. The motor is used to drive the screw rod to move, so that the pushing member 60 can move along the X axis relative to the sliding seat 50.

[0042] The above description is about the spindle 3 moving only along the Z axis. If the spindle 3 is capable of moving along the X axis and the Z axis, the X axis driving unit 80 is not needed.

[0043] Please refer to the following: Figures 6 to 10 The diagram illustrates the steps and process of performing the tool loading operation according to the present invention. Figure 6 As shown, one of the tool-carrying units 10 is driven by a corresponding Z-axis lifting unit 40, which in turn causes the lifting frame 11 to lower the tool holder 12 along the Z-axis to the tool change preparation position P2. At this time, the pushing member 60 is moved by the slide 50 to below the lifting frame 11, and the connecting post 61 is aligned with the connecting hole 1222. After the tool holder 12 lowers along the Z-axis to the tool change preparation position P2, the connecting hole 1222 and the connecting post 61 engage and position each other, thereby fixing the tool holder 12 onto the pushing member 60.

[0044] like Figure 7 As shown and in conjunction with Figure 5 As the slide 50 moves along the Y-axis toward the spindle 3, the pusher 60 drives the tool holder 12 to move toward the spindle 3. At this time, the ball 1131 is subjected to force and elastically contracts, causing it to detach from the recess 1221, and causing the lifting frame 11 of the tool carrying unit 10 to disengage from the positioning block 122 of the tool holder 12.

[0045] like Figure 8 As shown, continuing Figure 7 When the lifting frame 11 disengages from the positioning block 122, the lifting frame 11 can rise along the Z-axis back to its original position, while the tool holder 12 moves towards the spindle 3 to the tool changing position P3 below the spindle 3.

[0046] like Figure 9 As shown, the spindle 3 moves down along the Z-axis so that the spindle hole is connected to the corresponding tool holder A on the tool holder 12 and the tool gripping action is completed. Then it moves up to the original position so that the spindle 3 can remove the tool holder A from the tool holder 12 for subsequent machining operations.

[0047] like Figure 10 As shown, after the aforementioned tool loading action is completed, the slide 50 drives the tool holder 12 to the aforementioned position. Figure 6 The tool change preparation position P2 is reset to await the next tool change requirement. Accordingly, when the tool holder A of the spindle 3 needs to be replaced again, the tool holder 12 moves to the tool change position P3 according to the aforementioned action, with the empty tool holder 121 (without tool holder A installed), so that the old tool holder A on the spindle 3 can be placed in the tool holder 121. Then, in conjunction with the X-axis displacement of the aforementioned pusher 60 and the up-and-down displacement of the spindle 3 along the Z-axis, the spindle 3 can connect to and remove the other tool holder A from the tool holder 12, thus completing the tool change operation. When all tool holders A on the tool holder 12 have been used or replaced, the operation can be reversed according to the aforementioned action description, and the tool carrying unit 10 can send the tool holder 12 back to the previous position. Figure 2 The tool storage position P1 is then replaced with another set of new tool carrier unit 10 tool holder 12. Thus, through the aforementioned structural principle, this invention achieves the purpose of tool loading and tool changing.

[0048] It is worth mentioning that in some embodiments, the processing machine 1 is a gantry type, and the column 5 has a through space, so that the tool storage device 7 is located behind the column 5 and moves from the rear to the front to perform operations when changing tools.

[0049] In some embodiments, when the number of the aforementioned tool holders 12 is small, the Z-axis lifting unit 40 can be controlled by a cylinder to control the up and down displacement.

[0050] like Figure 11 As shown, another embodiment of the present invention is provided, in which the difference from the previous embodiment is that the tool exchange device 8 can be mounted on one side of the work platform 2, and the work platform 2 has the ability to move along the X-axis and Y-axis, thus eliminating the need for the aforementioned Y-axis drive unit 70 and X-axis drive unit 80 and other components.

[0051] In other possible embodiments, in addition to the positioning of the positioning block 122 and the side rod 111 by the elastically telescopic ball 1131 of the positioning member 113, a permanent magnet / electromagnet can also be used to replace the positioning member 113, so that the positioning block 122 and the side rod 111 are fixed to each other by magnetic attraction. Besides being applicable to vertical machining centers as described above, this invention can also be applied to horizontal machining centers. Simply change the direction of the tool storage and tool holder of the tool holder 12 to the horizontal direction in the horizontal spindle direction of the horizontal machining center, and the tool changing action can be smoothly performed in conjunction with this invention when the spindle moves horizontally.

[0052] Based on the above description, the present invention has the following advantages:

[0053] 1. The tool changing action of the present invention is as follows: after the tool holder 12 moves from the tool storage position P1 to the tool changing preparation position P2, it is then driven by the slide 50 of the tool changing device 8 to move down to the tool changing position P3 to perform the tool changing operation. This makes the tool holder 12 only move in the Z-axis and Y-axis directions before the tool changing position P3. This simplifies the action required to change the tool holder 12, greatly shortens the time to change the tool holder 12, and thus improves the efficiency of tool changing and machining.

[0054] 2. The tool storage device 7 of the present invention is located in front of the spindle 3 and above the work platform 2, which can reduce the space occupied on the machine tool.

[0055] 3. The multiple tool carrying units 10 of the tool storage device 7 of the present invention can simultaneously store multiple sets of tool holders A for applications requiring multiple tools, and can expand the applicability of tool changing to meet diverse processing needs.

[0056] The present invention has been described above with reference to several embodiments. Those skilled in the art can make various modifications without departing from the spirit and scope of the present invention.
