[0041] Reference Figure 1 According to an embodiment of the present application, the tool magazine includes: a tool disc 100, a protective cover 200 and a shielding assembly 300.

[0042] Reference Figure 8 The cutter head 100 is provided with a plurality of cutter-setting structures 110 along the circumferential direction, and the cutter-setting structures 110 are used to clamp the cutter 700;

[0043] Reference Figure 1 、 Figure 2 and Figure 7 The protective cover 200 is located on the inner side of the cutter head 100. The protective cover 200 is formed with a receiving groove 210 extending in the circumferential direction. Part of the blade-holding structure 110 is at least partially located in the receiving groove 210. The receiving groove 210 is used to accommodate the handle 710 of the cutter 700. The protective cover 200 is formed with a notch 220. The notch 220 is connected to the receiving groove 210. One of the blade-holding structures 110 corresponds to the notch 220. The cutter head 100 can rotate relative to the protective cover 200 to allow the blade-holding structure 110 to move in the receiving groove 210, and different blade-holding structures 110 can be moved to the notch 220.

[0044] Reference Figure 1 、 Figure 2 and Figure 4 The shielding component 300 is arranged on the blade disc 100, and a plurality of shielding components 300 are provided. The shielding components 300 correspond one to one with the blade placement structure 110; the shielding component 300 is located on the side of the blade placement structure 110 away from the accommodating groove 210, and the shielding component 300 is formed with a blade removal port 312 that can be opened and closed.

[0045] It is understandable that, referring to Figure 6 The tool placement structure 110 can hold the tool 700, and the tool handle 710 of the tool 700 will be located in the receiving groove 210 of the protective cover 200. Therefore, during the processing of the processing equipment, the tool handle 710 can be protected by the protective cover 200 to prevent debris from splashing onto the tool handle 710, thereby ensuring the assembly accuracy of the main shaft of the processing equipment and the tool 700, and ensuring the processing quality of the processing equipment on the parts. It can also be understood that, with reference to Figure 2 and Figure 3 The knife-setting structure 110 at the notch 220 can be unloaded, that is, no knife 700 is placed on the knife-setting structure 110 at the notch 220, so there is no problem of debris adhering to the knife 700.

[0046] It is understood that when the spindle needs to replace the tool 700, the tool 700 that the spindle needs to replace is defined as the target tool 700. It should be understood that at this time, referring to Figure 2 and Figure 3The tool placement structure 110 at the notch 220 is unloaded, the tool removal opening 312 of the shielding assembly 300 at the notch 220 is opened, and the spindle can place the tool 700 installed on the spindle on the tool placement structure 110 at the notch 220 . Subsequently, the cutter disc 100 can rotate relative to the protective cover 200. Since the tool placement structure 110 is distributed in the circumferential direction and the accommodating groove 210 extends in the circumferential direction, the tool placement structure 110 and the tool handle 710 of the tool 700 on the tool placement structure 110 can move in the circumferential direction within the accommodating groove 210, so that the tool placement structure 110 originally located at the notch 220 can be transferred into the accommodating groove 210, and the tool placement structure 110 equipped with the target tool 700 can be moved from the accommodating groove 210 to the notch 220. The tool handle 710 of the tool 700 located at the notch 220 will be located outside the accommodating groove 210, and the spindle can grab the tool 700 on the tool placement structure 110 located at the notch 220, thereby realizing tool change.

[0047] It is understood that the shielding assembly 300 is located on the side of the knife-holding structure 110 away from the receiving groove 210. The shielding assembly 300 cooperates with the protective cover 200 to further protect the handle 710 of the knife 700 and further reduce the possibility of debris splashing onto the handle 710. Specifically, the knife-taking opening 312 of the shielding assembly 300 is opened to enable the knife 700 to be inserted into the knife-holding structure 110. It should be understood that, referring to Figure 6 At this time, the blade head 720 of the tool 700 protrudes from the tool placement structure 110 through the blade removal opening 312, and the blade head 720 faces away from the protective cover 200. The tool 700 will block the shielding assembly 300 from closing the blade removal opening 312. However, the tool 700 itself can block the blade removal opening 312, thereby preventing debris from splashing into the receiving groove 210 through the blade removal opening 312. Figure 4 When the knife-setting structure 110 rotates to the notch 220 and the knife 700 on the knife-setting structure 110 is removed, the shielding component 300 can shield its knife-taking edge 312, thereby shielding the knife-taking edge 312 and preventing debris from splashing into the accommodating groove 210 through the knife-taking edge 312.

[0048] Reference Figure 3 and Figure 7 According to some embodiments of the present application, the accommodating groove 210 passes through the protective cover 200 to form two opposite openings 230 on the protective cover 200, the notch 220 is located between the two openings 230, and the accommodating groove 210 is connected to the notch 220 through the opening 230.

[0049] It can be understood that when the cutter disc 100 rotates relative to the protective cover 200, the knife-setting structure 110 located at the notch 220 can be rotated into the accommodating groove 210 through one of the openings 230, and the knife-setting structure 110 located in the accommodating groove 210 can be rotated to the notch 220 through the other opening 230, so that all the knife-setting structures 110 can be rotated to the notch 220 to ensure that the knife 700 on each knife-setting structure 110 can be grasped.

[0050] Reference Figure 1 and Figure 3 According to some embodiments of the present application, a dustproof component 400 is also included. The dustproof component 400 includes a dustproof plate 410 and a dustproof driver 420. The dustproof driver 420 drives the dustproof plate 410 to cover or open the opening 230.

[0051] It is understood that when the spindle needs to replace the tool 700, the dustproof driver 420 drives the dustproof plate 410 away from the opening 230 and opens the opening 230, allowing the receiving groove 210 to communicate with the notch 220 through the opening 230. This allows the tool placement structure 110 at the notch 220 to enter the receiving groove 210 through the opening 230, and allows the tool placement structure 110 in the receiving groove 210 to pass through the opening 230 to reach the notch 220. When the spindle is processing, the dustproof driver 420 drives the dustproof plate 410 to cover the opening 230, thereby preventing debris from entering the receiving groove 210 through the opening 230.

[0052] Specifically, two dustproof components 400 are provided, corresponding to the two openings 230 respectively.

[0053] Reference Figure 4 and Figure 5 According to some embodiments of the present application, the shielding assembly 300 includes a fixed part 310, a shielding part 320 and an elastic part 330. The fixed part 310 and the shielding part 320 are movably connected. A knife-taking edge 312 is formed on the fixed part 310. The shielding part 320 is provided with a first connecting structure 321, and the fixed part 310 is provided with a second connecting structure 311. The two ends of the elastic part 330 are respectively connected to the first connecting structure 321 and the second connecting structure 311. The elastic part 330 is used to drive the shielding part 320 to shield the knife-taking edge 312.

[0054] It will be understood that the fixed portion 310 is fixed to the blade disc 100, and when the blade disc 100 rotates, the fixed portion 310 rotates with it. The shielding portion 320 is movable relative to the fixed portion 310, and the shielding actuator 500 can drive the shielding portion 320 to open the blade removal opening 312, thereby facilitating the insertion of the blade 700 into the blade receiving structure 110 or the removal of the blade 700 from the blade receiving structure 110. The elastic portion 330 is connected at both ends to the first connecting structure 321 and the second connecting structure 311, respectively. The elastic portion 330 pulls on the shielding portion 320, causing it to tend to cover the blade removal opening 312. Therefore, when the blade removal opening 312 is not occupied by the blade 700, the shielding portion 320 can automatically return to its original position under the action of the elastic portion 330, so that the shielding portion 320 continues to cover the blade removal opening 312. Moreover, when the tool 700 is stuck in the tool placement structure 110, the shielding portion 320 will be pulled against the outside of the tool 700 by the elastic portion 330, so that the shielding portion 320 is close to the outside of the tool 700, preventing debris from flying into the accommodating groove 210 from the gap between the shielding portion 320 and the tool 700.

[0055] Specifically, there are multiple second connection structures 311 and multiple elastic parts 330 . The second connection structures 311 and the elastic parts 330 correspond one to one, and multiple second connection structures 311 correspond to one first connection structure 321 .

[0056] Specifically, in this embodiment, referring to Figure 4 and Figure 5 The fixing portion 310 and the shielding portion 320 slide relative to each other, and the shielding portion 320 slides to cover or open the knife-taking opening 312. In other embodiments, the shielding portion 320 and the fixing portion 310 can be hinged, and the shielding portion 320 can be rotated to cover or open the knife-taking opening 312.

[0057] According to some embodiments of the present application, the first connection structure 321 is a first protrusion or a first groove provided on the shielding portion 320 , and the second connection structure 311 is a second protrusion or a second groove provided on the fixing portion 310 .

[0058] It is understood that in some embodiments, reference Figure 4 and Figure 5 The first connecting structure 321 is a first protrusion, and the second connecting structure 311 is a second protrusion, which can facilitate the connection of the elastic portion 330 with the first connecting structure 321 and the second connecting structure 311. In some other embodiments, the first connecting structure 321 is a first groove, and the second connecting structure 311 is a second groove, and the two ends of the elastic portion 330 are snapped into or embedded in the first groove and the second groove, reducing production costs.

[0059] Regarding how to make the shielding portion 320 open the knife-taking opening 312, in some embodiments, refer to Figure 1 and Figure 2 , and also includes a shielding driver 500, which drives the connected shielding part 320 to drive the shielding part 320 to open the knife-taking edge 312.

[0060] It is understood that when the shielding actuator 500 is not driving the shielding portion 320, the elastic portion 330 pulls the shielding portion 320, causing the shielding portion 320 to have a tendency to cover the opening 230. When the shielding actuator 500 drives the shielding portion 320 to open the blade removal opening 312, the elastic portion 330 is stretched and has a tendency to contract. When the shielding actuator 500 stops driving the shielding portion 320, the elastic portion 330 pulls the shielding portion 320 to cover the opening 230.

[0061] In some embodiments, during the spindle tool change process, the shielding plate can be pushed open by the tool 700 to allow the tool 700 to be inserted into the tool placement structure 110 .

[0062] Regarding the arrangement of the shielding driver 500, in this embodiment, refer to Figure 1 and Figure 2 , only one shielding driver 500 is provided, and the shielding driver 500 is provided corresponding to the notch 220, and a through groove 511 is formed on the driving end 510 of the shielding driver 500; the first connecting structure 321 on the shielding portion 320 corresponding to the notch 220 is located in the through groove 511, and the first connecting structure 321 can enter and exit the through groove 511 when the cutter disc 100 rotates. When the shielding driver 500 drives the shielding portion 320, the inner wall of the through groove 511 can abut against the first connecting structure 321 located in the through groove 511.

[0063] It can be understood that when the blade disc 100 drives the blade setting structure 110 to rotate, the rotation path of the first connecting structure 321 passes through the through groove 511. Therefore, when the blade setting structure 110 rotates to the notch 220, the shielding part 320 corresponding to the blade setting structure 110 also moves to correspond to the notch 220, and the first connecting structure 321 on the shielding part 320 will move into the through groove 511. The shielding driver 500 drives its driving end 510 to extend and retract, and the inner wall of the through groove 511 is against the first connecting structure 321, and the shielding part 320 is driven to translate relative to the fixed part 310 through the first connecting structure 321, so that the shielding part 320 opens the blade removal opening 312.

[0064] In some other embodiments, a plurality of shielding drivers 500 may be provided, and correspond one-to-one to the shielding components 300 . The shielding drivers 500 are provided on the cutter disc 100 and can rotate relatively with the cutter disc 100 .

[0065] It can also be understood that by connecting the elastic part 330 through the first connecting structure 321 and cooperating with the shielding driver 500 to drive the shielding part 320, the first connecting structure 321 can cooperate with the elastic part 330 to close the knife-taking edge 312 and cooperate with the shielding driver 500 to open the knife-taking edge 312, thereby improving the utilization of the structural space.

[0066] Reference Figure 2 According to some embodiments of the present application, it also includes a shell 600 and a connecting rod 610. The cutter disc 100 is arranged on the inner side of the shell 600 and is located between the shell 600 and the protective cover 200. The cutter disc 100 can rotate relative to the shell 600. One end of the connecting rod 610 is rotatably connected to the shell 600, and the other end of the connecting rod 610 is connected to the shielding driver 500.

[0067] It is understood that the housing 600 can be positioned over one side of the cutterhead 100 to protect it, and the blade-receiving structure 110 is positioned between the housing 600 and the protective cover 200. The housing 600 and the protective cover 200 can further enhance the chip protection of the blade handle 710. Furthermore, the cutterhead 100 can rotate relative to the housing 600, allowing the blade-receiving structure 110 to rotate between the housing 600 and the protective cover 200.

[0068] It is also understood that the shield driver 500 is connected to the housing 600 via the connecting rod 610, and the cutter head 100 can rotate relative to the shield driver 500, so that different blade placement structures 110 move to positions corresponding to the shield driver 500. Furthermore, because the connecting rod is rotatably connected to the housing 600, the position of the shield driver 500 relative to the notch 220 can be adjusted to ensure the accuracy of the driving position of the shield driver 500 relative to the first connecting structure 321.

[0069] Reference Figure 6 and Figure 7 According to some embodiments of the present application, the protective cover 200 includes an outer baffle 240, an inner baffle 250 and a connecting plate 260. The outer baffle 240 is located on the side of the blade structure 110 away from the outer shell 600, and the inner baffle 250 is located on the side of the blade structure 110 close to the outer shell 600. The connecting plate 260 respectively connects the ends of the outer baffle 240 and the inner baffle 250 away from the blade structure 110.

[0070] It is understood that the receiving groove 210 is formed between the outer baffle 240, the inner baffle 250, and the connecting plate 260, and cooperates with the shield assembly 300 to surround the handle 710 of the cutting tool 700. Specifically, the outer baffle 240 and the inner baffle 250 are arranged at an angle relative to each other and approach each other in a direction away from the shield assembly 300 to adapt to the outer shape of the handle 710, thereby reducing the space occupied by the protective cover 200.

[0071] Reference Figure 4 According to some embodiments of the present application, the cutting edge 312 passes through one side of the fixing portion 310 along the insertion direction of the knife 700 on the knife placement structure 110, so that a cutting edge 313 is formed on one side of the fixing portion 310.

[0072] It is understood that the cutting tool 700 is inserted into the cutting groove 111 of the cutting tool receiving structure 110 along the side of the cutting tool receiving structure 110. By providing the cutting tool entry opening 313 on the fixing portion 310, the cutting tool 700 can enter the cutting tool removal opening 312 through the cutting tool entry opening 313 during the process of inserting the cutting tool 700 into the cutting tool receiving structure 110 from the side. Similarly, when it is necessary to remove the cutting tool 700 from the cutting tool receiving structure 110, the cutting tool 700 can exit the cutting tool removal opening 312 through the cutting tool entry opening 313.

[0073] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
