The machine tool 10 is provided with a machine base 11 and a column 12 arranged on the machine base 11. The column 12 is provided with at least one spindle 13. A working area 14 for processing workpieces is provided between the machine base 11 and the spindle 13. A workbench 15 is provided in the working area 14. The spindle 13 is provided with a tool changing position 16 at a corresponding position of the working area 14, and the spindle 13 can slide toward or away from the tool changing position 16. The barrel-type tool magazine mechanism includes: A knife storage device 20 is mounted above the working area 14 in front of the spindle 13. In other feasible embodiments, if the column 12 is a gantry column, the knife storage device 20 can be arranged on the other side of the column 12 relative to the spindle 13. The knife storage device 20 includes at least a first knife storage area 21 and a second knife storage area 22. The first knife storage area 21 and the second knife storage area 22 are arranged side by side, and the first knife storage area 21 is closer to the spindle 13 than the second knife storage area 22 (e.g. Figure 7 As shown in FIG. 1 , the first knife storage area 21 and the second knife storage area 22 can be used to stack and accommodate a plurality of knife racks 30. The lower end of the first knife storage area 21 is open and forms a knife rack return position 211, and the lower end of the second knife storage area 22 is open and forms a knife rack removal position 221.

[0032] Furthermore, the upper ends of the first knife storage area 21 and the second knife storage area 22 are connected, and a knife storage translation device 23 is provided, and the knife storage translation device 23 can drive the knife holder 30 to move at the upper ends of the first knife storage area 21 and the second knife storage area 22. In a feasible embodiment, the knife storage translation device 23 includes a translation cylinder 231, and the translation cylinder 231 is connected to a lever 232, and the lever 232 can drive the knife holder 30 to move at the upper end of the first knife storage area 21 and the second knife storage area 22.

[0033] Furthermore, the knife storage device 20 further includes a frame 24, which is arranged and covered at the outer periphery of the first knife storage area 21 and the second knife storage area 22, and the frame 24 is provided with at least one first clearance groove 241 and at least one second clearance groove 242 on the sides of the first knife storage area 21 and the second knife storage area 22.

[0034] The tool holder 30 includes a base body 31 disposed on both sides, and a plurality of tool clamps 32 disposed between the base bodies 31. The tool clamps 32 can be used to movably fix a processing tool 90 thereon. An engaging protrusion 311, at least one locking hole 312 and at least one toggle block 313 are disposed on the outer side of the base body 31. In a preferred embodiment, the engaging protrusion 311 is disposed horizontally and protrudes outward near the middle section of the outer side of the base body 31, wherein the engaging protrusion 311 is further provided with at least one protrusion locking hole 3111 and at least one fixing hole 3112. There are two toggle blocks 313, which are disposed at the upper end of the outer side of the base body 31 and protrude outward, and the locking hole 312 is located between the two toggle blocks 313. Furthermore, the frame 24 is provided with a stopping edge 243 (such as Figure 7 As shown), so that the toggle block 313 of the tool holder 30 located at the tool holder removal position 221 can be hooked and fixed, and a support block 244 (as shown) is provided. Figure 7 As shown), it is used for supporting and limiting the position when the tool holder 30 is replaced.

[0035] At least one tool storage lifting device 40 is disposed on the side of the tool storage device 20, and can drive the tool holders 30 in the first tool storage area 21 and the second tool storage area 22 to generate lifting displacement, so as to transport the tool holder 30 from the tool return position 211 to the first tool storage area 21, and transport the tool holder 30 from the second tool storage area 22 to the tool pick-up position 221, so as to provide a tool exchange device 50 to transport and displace the tool holder 30 between the tool change position 16, the tool return position 211 and the tool pick-up position 221. The tool storage lifting device 40 includes at least one drive cylinder 41 disposed on the side of the frame 24, and a lifting seat 42 that can be driven to lift by the drive cylinder 41, and the lifting seat 42 is disposed adjacent to the first clearance groove 241 and the second clearance groove 242. The lifting seat 42 is provided with an extension block 421 corresponding to the first clearance groove 241 . The extension block 421 can extend from the first clearance groove 241 into the first knife storage area 21 to movably abut against the shifting block 313 of the knife holder 30 .

[0036] Among them, the frame 24 is provided with at least one locking device 43 at the side of the first knife storage area 21, and the locking device 43 is movably engaged with the locking hole 312 of one of the knife holders 30 in the first knife storage area 21. The locking device 43 is an elastically contractible wedge block device, and the end of the wedge block device is a wedge-shaped inclined surface shape with a longer upper part and a shorter lower part, and the wedge block device has an elastic force that normally pushes against the first yielding groove 241, so that when the knife holder 30 in the first knife storage area 21 moves from bottom to top, the wedge-shaped inclined surface of the locking device 43 can automatically and elastically retract after being stressed, so that the knife holder 30 can pass smoothly. On the contrary, when the knife holder 30 in the first knife storage area 21 moves from top to bottom, the locking device 43 can be fixed in the locking hole 312 of the knife holder 30 to prevent the knife holder 30 from moving downward, thereby forming an effect that the knife holder 30 can only move upward in the first knife storage area 21.

[0037] The lifting seat 42 is provided with a power locking device 44 corresponding to the second clearance groove 242. The power locking device 44 is a power cylinder having an axial end 441 that can extend into the second clearance groove 242 and movably engage with a locking hole 312 of one of the tool holders 30 in the second tool storage area 22.

[0038] In addition, the tool exchange device 50 includes a sliding seat 51, and the sliding seat 51 includes at least a slide rail 52 and a driving device 53 to drive the sliding seat 51 to move on the slide rail 52. A fitting frame 54 is provided on both sides of the sliding seat 51, and the fitting frame 54 can be movably fitted in the fitting protrusion 311 of the tool holder 30. Among them, the fitting frame 54 is provided with at least one clamping device 541 and a locking hole cylinder 542, and the shaft of the locking hole cylinder 542 can be movably extended into the protrusion locking hole 3111 provided on the fitting protrusion 311 to ensure that the fitting protrusion 311 and the fitting frame 54 are firmly combined. The locking device 541 can be a spring top ball. When the locking frame 54 is engaged with the locking protrusion 311 of the tool holder 30 and the locking hole cylinder 542 is not locked in the locking hole 3111 of the locking protrusion 311, the locking device 541 can be elastically locked in the locking hole 3112 to provide a locking force to prevent the tool holder 30 from disengaging. The locking device 541 can also be a magnetic device to provide a locking force by magnetically attracting the locking protrusion 311.

[0039] In other feasible embodiments, a lateral displacement device 55 is further provided between the sliding seat 51 and the slide rail 52, and the lateral displacement device 55 includes a lateral slide rail 551 and a lateral driving device 552, so that the tool exchange device 50 can drive the tool holder 30 to lateral displacement. Thereby, when the tool exchange device 50 carries the tool holder 30 to move to the tool changing position 16, the lateral displacement device 55 can be lateral displacement to switch different tool holders 32 to align with the spindle 13, so as to facilitate the spindle 13 to take out or return the processing tool 90 from different tool holders 32. Furthermore, in other feasible implementation cases, a loading and unloading device (not shown) can be installed on the tool exchange device 50 for taking out and replacing the workpiece, or a chip blowing device (not shown) can be installed to clean the workbench or the fixtures thereon, etc., so as to increase the functionality of the present invention.

[0040] After understanding the detailed structure of the present invention, the following describes the working principle of the present invention in detail: like Figure 4 And refer to Figures 1 to 3 As shown in the content, in a preferred embodiment, the tool changing position 16, the tool holder return position 211 and the tool holder removal position 221 are in the same horizontal plane. When the tool exchange device 50 carries the tool holder 30 to the tool changing position 16, the spindle 13 can slide toward or away from the tool changing position 16 and cooperate with the action of the tool exchange device 50 to remove or return the machining tool 90.

[0041] When the machining tool 90 of the tool holder 30 is used up and the tool exchange device 50 and the spindle 13 complete the tool return operation, the locking cylinder 542 will release the tool holder 30 (hereinafter referred to as the ready tool holder 30A) carrying the machining tool 90 to be replaced. At this time, the ready tool holder 30A is elastically fixed by the fixing device 541.

[0042] At the same time as the above-mentioned action, the lifting seat 42 of the tool storage lifting device 40 descends to the lower end of the tool storage device 20. At this time, the extension block 421 on the lifting seat 42 and the tool holder 30 (hereinafter referred to as the raw tool holder 30B) locked by the power locking device 44 and carrying the new processing tool 90 are also brought to the lower end of the tool storage device 20.

[0043] Then, the shaft end 441 of the power locking device 44 retracts and disengages from the locking hole 312 of the raw knife holder 30B, so that the shifting block 313 of the raw knife holder 30B is abutted by the blocking edge 243 .

[0044] When the above two actions are completed, the tool exchange device 50 returns the cooked tool holder 30A to the tool holder return position 211 and continues to move toward the tool holder removal position 221. During this process, the cooked tool holder 30A is supported by the raw tool holder 30B, and the raw tool holder 30B is supported by the positioning block 244, so that the cooked tool holder 30A slides out of the engaging frame 54 and stays at the tool holder return position 211 and is abutted by the extension block 421. As the tool exchange device 50 moves toward the tool holder removal position 221, its engaging frame 54 slides and engages with the engaging protrusion 311 of the raw tool holder 30B again.

[0045] Then, if Figure 5 As shown, the locking cylinder 542 of the engaging frame 54 rises to lock the raw knife holder 30B, and the driving cylinder 41 drives the lifting seat 42 to move upward. Before that, the extension block 421 of the lifting seat 42 is in contact with the shifting block 313 of the prepared knife holder 30A, so the prepared knife holder 30A is driven by the lifting seat 42 from the return knife holder position 211 to the first knife storage area 21, and the raw knife holder 30B is retained at the removal knife holder position 221 because it is engaged with the engaging frame 54 of the tool exchange device 50.

[0046] like Figure 6As shown, when the knife storage lifting device 40 drives the cooked knife rack 30A to rise, the locking hole 312 of another knife rack 30 above it is automatically disengaged from the locking device 43 due to the forward movement. Since the height of each rise of the knife storage lifting device 40 is slightly equal to the height of one knife rack 30, the locking hole 312 of the cooked knife rack 30A will be re-locked by the locking device 43 and stay in the first knife storage area 21, and block the knife rack 30 in the first knife storage area 21 from moving downward. At the same time, the power locking device 44 of the lifting seat 42 will align with the locking hole 312 of the knife rack 30 on the raw knife rack 30B after rising, and the shaft end 441 of the power locking device 44 will be driven to extend into the locking hole 312 (such as Figure 8 As shown in FIG. 1 , the tool rest 30 is kept at a height. The tool rest 30B at the tool rest position 221 is in a free state and can be driven by the tool exchange device 50 to move to the tool exchange position 16 to provide a new machining tool 90 for the spindle 13 to exchange.

[0047] like Figure 7 As shown, after the tool holder 30 in the first tool storage area 21 rises, it will be one tool holder 30 higher than the second tool storage area 22 next to it. At this time, the lever 232 of the tool storage translation device 23 will contact the top tool holder 30 in the first tool storage area 21. When the translation cylinder 231 drives the lever 232 to move toward the second tool storage area 22, the lever 232 can drive the top tool holder 30 to move from the first tool storage area 21 to the second tool storage area 22. Then, as shown in FIG. Figure 8 As shown, since the shaft end 441 of the power locking device 44 is now clamped in the locking hole 312 of the bottom tool holder 30 of the second tool storage area 22, when the lifting seat 42 descends again, the bottom tool holder 30 of the second tool storage area 22 can be sent to the tool holder retrieval position 221 to wait for the next tool holder retrieval operation of the tool exchange device 50.

[0048] It is worth mentioning that, since the number of tool holders 32 of the tool rest 30 can be designed to be a multiple of the number of spindles 13, the number of tools carried by the tool rest 30 can be increased. At the same time, through the setting of the lateral displacement device 55, different tool holders 32 can be switched to align with the spindle 13 as needed. Only one tool rest 30 needs to be taken from the tool storage device 20 for multiple tool changes for the spindle 13, which is more conducive to saving tool change time. Furthermore, since the tool rest position 211 is usually in an idle (no tool rest 30) state, the tool rest position 211 can be used as a buffer zone, so that the tool 90 on the tool rest 30 carried by the tool exchange device 50 can be moved to the tool rest position 211 before it is used up to avoid affecting the processing of the spindle 13. At the same time, since there is no need to set an additional evasive buffer zone between the tool rest position 211 and the tool change position 16, the stroke length of the tool change device 50 can be shortened, which is more conducive to shortening the tool change time and stroke.

[0049] In addition, if Fig. 9As shown, in a possible embodiment, the engaging frame 54 of the tool exchange device 50 can also be directly set on the workbench 15, and driven by the workbench 15 to move between various positions to achieve the purpose of exchanging tools.

[0050] like Fig.10 , 11 As shown, a rotary drive device 543 can be added to the interlocking frame 54 to rotate the tool holder 30 to achieve the function of multi-angle tool change. In this way, the tool holder 32 and the tool 90 on the tool holder 30 can be placed according to the machine structure design, and are not restricted by the vertical direction. Only by using the rotary drive device 543 to drive the tool holder 30 on the tool exchange device 50 to rotate, the tool change direction of the spindle 13 can be matched, making the present invention more flexible and applicable to more machine structure designs of the machine tool 10.

[0051] In addition, the first tool storage area 21 and the second tool storage area 22 of the present invention can also be designed to exchange positions so that the second tool storage area 22 is closer to the spindle 13 than the first tool storage area 21. Only by changing the moving trajectory of the tool exchange device 50, the same purpose and effect can be achieved.

[0052] With the above structure, the advantages of the present invention are as follows: 1. The tool storage method of stacking tool holders 30 in the first tool storage area 21 and the second tool storage area 22, and the tool storage lifting device 40, the lifting seat 42, the locking device 43 and the power locking device 44 are used to control the switching of the tool holders 30 in the tool storage device 20, providing a simple and reliable tool storage method without the need for a complex or precision control structure, thereby reducing the setting cost of the tool magazine.

[0053] 2. By means of the parallel return tool holder position 211 and the take-out tool holder position 221, the tool exchange device 50 can quickly complete the exchange operation of the raw and cooked tool holders, thereby reducing the tool change time.

[0054] 3. The knife storage translation device 23 can switch the knife holder 30 between the first knife storage area 21 and the second knife storage area 22 through the upper ends connected to each other, so that the knife holder 30 for pre-storing raw knives in the first knife storage area 21 can be exchanged one by one to the second knife storage area 22 during the knife exchange process. In this way, the present invention can increase the knife storage capacity of the knife holder 30. In addition, the present invention can also stagger the upper and lower knife holders 30 to reduce the height of the knife storage device 20 and increase the knife storage capacity.

[0055] 4. By adding a rotary drive device 543 to the interlocking frame 54 of the tool exchange device 50, tool exchange at multiple angles can be achieved, thereby increasing the versatility and flexibility of the present invention.

[0056] 5. The tool holder 30 can be installed with tool holders 32 of the same or different specifications according to different requirements to fix processing tools 90 of the same or different specifications.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
