[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 8As shown, this utility model embodiment provides a tool magazine, which includes: a body, including a housing 11 and a tool holder 12, the housing 11 having a receiving cavity 110, the tool holder 12 being rotatably disposed within the receiving cavity 110, the tool holder 12 being used to hold tools 13; a first blowing mechanism 20, disposed on the housing 11, the first blowing mechanism 20 having a first air inlet 201 and a first air outlet 202, the first air inlet 201 being connected to an air source, the first air outlet 202 being located within the receiving cavity 110 and correspondingly disposed with respect to the tool 13, for blowing away the tool 13; and a second blowing mechanism 30, disposed on the housing 11, the second blowing mechanism 30 having a second air inlet 301 and a second air outlet 302, the second air inlet 301 being connected to an air source, the second air outlet 302 being located outside the receiving cavity 110 and correspondingly disposed with respect to the top surface of the housing 11, for blowing away impurities on the surface of the housing 11.

[0033] Applying the technical solution of this utility model, the tool magazine includes a first blowing mechanism 20 and a second blowing mechanism 30. The first blowing mechanism 20 can blow the outer surface of the housing 11 before the tool magazine starts working, thereby blowing away debris or impurities on the outer surface of the housing 11 and preventing debris and other impurities from accumulating on the outer surface of the housing 11 or on the components on the outer surface, thus affecting the normal operation of the components. The second blowing mechanism 30 can blow away the tools 13 inside the housing 11 before the tool magazine starts working, thereby blowing away impurities on the tools 13 and preventing impurities on the surface of the tools 13 from entering between the tools 13 and the tool holder 12 or other mating components and causing jamming, thus affecting subsequent tool changing operations. The above settings can reduce the accumulation or jamming of components due to debris and other impurities during the operation of the tool magazine, ensuring the stability of the tool magazine operation.

[0034] Furthermore, the housing 11 has a first opening that communicates with the receiving cavity 110. The first opening extends from the top of the housing 11 to the side wall of the housing 11. The body also includes a first rotating door 14, which is correspondingly arranged with the first opening. The first rotating door 14 can rotate relative to the housing 11 to open or close the first opening. The first air outlet 202 faces the portion of the first opening located on the side wall of the housing 11 to blow away the blade 13 located at the first opening. When the first rotating door 14 is opened, impurities are likely to fall from the first opening onto the blade 13. Therefore, the first air outlet 202 is arranged facing the first opening to specifically clean the blade 13, which is prone to accumulating debris. The second air outlet 302 faces the surface of the top of the housing 11 near the first opening to blow away impurities on the surface of the top of the housing. This can prevent debris from accumulating between the top surface of the housing 11 and the first rotating door 14, thereby preventing the first rotating door from easily getting stuck when opened due to debris accumulation near the first opening at the top of the housing 11. The above configuration allows the first blowing mechanism 20 and the second blowing mechanism 30 to accurately blow the surfaces of the blade 13 and the top of the housing 11, enhancing the targeting and efficiency of the cleaning.

[0035] like Figure 2 As shown, the first blowing mechanism 20 includes a first blowing section 21 and a first connecting pipe 22. The first blowing section 21 is located within the receiving cavity 110 and is correspondingly arranged with the cutting tool 13. The first blowing section 21 has a first air outlet 202 on the side near the cutting tool 13 and a first connecting port 210 connected to the first air outlet 202. One end of the first connecting pipe 22 is connected to the first connecting port 210, and the end of the first connecting pipe 22 away from the first blowing section 21 has a first air inlet 201. The first connecting pipe 22, as a carrier for airflow transmission, guides high-pressure gas to the first blowing section 21, which then acts directly on the surface of the cutting tool through the first air outlet 202, achieving precise blowing, improving the accuracy and efficiency of cutting tool cleaning, and ensuring processing quality.

[0036] In this embodiment, the first connecting pipe 22 is a flexible hose, which makes it convenient to extend, wind around, fix, and adjust according to different structures at different locations of the tool magazine, thus improving the flexibility of the pipeline layout.

[0037] like Figure 2As shown, the first blowing unit 21 includes a first connecting block 211 and a plurality of first air outlet pipes 212. The first connecting block 211 is disposed on and detachably connected to the housing 11. The first connecting block 211 has a plurality of first air outlet holes 213, and a first connecting opening 210 is disposed on the side wall of the first connecting block 211 and communicates with the plurality of first air outlet holes 213. The plurality of first air outlet pipes 212 are spaced apart on the first connecting block 211, and each of the plurality of first air outlet pipes 212 corresponds to one of the plurality of first air outlet holes 213. The end of each first air outlet pipe 212 away from the first connecting block 211 has a first air outlet 202. The first connecting block 211 achieves both dispersion and centralized control of the airflow, improving the coverage area and cleaning effect of the first blowing unit 21.

[0038] Specifically, the first air outlet 212 is a bamboo joint tube, which can adjust the degree of bending of the tube section and the orientation of the first air outlet 202, thereby improving the flexibility of the first blowing part 21 in blowing air.

[0039] In this embodiment, the first purging unit 21 includes three first air outlet pipes 212, which are respectively disposed corresponding to the three cutting tools 13.

[0040] The first connecting block 211 is fixed to the inner side wall of the sheet metal on the top of the housing 11 by fasteners.

[0041] like Figures 5 to 6 As shown, the tool magazine also includes a second connecting block 40, which is disposed on the top of the housing 11. The second connecting block 40 has interconnected air inlets 401 and multiple second air outlets 402. The air inlets 401 and the second air outlets 402 are respectively disposed on the side walls of the second connecting block 40. The air inlets 401 are connected to an air source, and at least two of the second air outlets 402 are connected to the first air inlet 201 and the second air inlet 301 respectively. The design of the second connecting block unifies the air source interfaces of the first purging mechanism 20 and the second purging mechanism 30, simplifies the air path connection, optimizes the air path design, eliminates the need for multiple air sources to supply air separately, reduces the complexity and cost of the air path system, and facilitates maintenance and management, thereby improving the reliability and stability of the system.

[0042] In other embodiments, the number of pores in the second connecting block 40 can be increased and the pore diameter can be adjusted to accommodate tools of different sizes and types, thus solving the problem that a single pore design cannot meet diverse needs.

[0043] Furthermore, multiple second air outlets 402 are respectively arranged at intervals on both sides of the air inlet 401 along the extension direction of the air inlet 401. This increases the connection options between the second connecting block 40 and the first purging mechanism 20 and the second purging mechanism 30. The second air outlets 402 at different positions can be connected according to the purging position requirements, further improving the purging flexibility. The inner sidewalls of the air inlet 401 and the inner sidewalls of the second air outlet 402 are both threaded. The second air inlet 301 is threaded to the threaded section through the air outlet connector 41. The threaded connection provides reliable sealing performance, which makes the connection between the second air inlet and the connecting block more firm and stable, and avoids air leakage.

[0044] Specifically, the second connecting block 40 is fixed to the outer side wall of the sheet metal on the top of the housing 11 by fasteners.

[0045] like Figure 1 As shown, the tool magazine also includes an air inlet pipe 50, which is connected to the second connecting block 40. The air inlet pipe 50 also includes a flow control valve 51 to regulate the air inlet flow rate.

[0046] like Figure 1 , Figure 7 and Figure 8 As shown, the second purging mechanism 30 includes a second purging section 31 and a second connecting pipe 34. The second purging section 31 includes a support 32 and a second air outlet pipe 33. The support 32 is fixed to the housing 11. One end of the second air outlet pipe 33 is fixed to the support 32, and the end of the second air outlet pipe 33 away from the support 32 faces the housing 11 and has a first air outlet 202. One end of the second connecting pipe 34 is connected to the second air outlet pipe 33, and the other end of the second connecting pipe 34 has a second air inlet 301. The design of the second purging section enables directional purging of the surface of the housing 11, improving cleaning efficiency, effectively removing debris from the surface of the housing 11, preventing debris from entering the tool magazine, and ensuring the normal operation of the tool magazine.

[0047] Preferably, the second connecting pipe 34 is a flexible hose, which makes it convenient to extend, wind around, fix, and adjust according to different structures at different positions of the tool magazine, improving the flexibility of the pipeline layout. The flexible hose can be fixed to the housing 11 by fasteners such as snap-fit ​​structures to reduce the vibration generated when gas flows inside the hose.

[0048] The support 32 includes a first section 321 and a second section 322 connected sequentially. The first section 321 is detachably connected to the housing 11, and the extension direction of the second section 322 forms an angle with the first section 321. The second section 322 has an oblong hole 323. The second purging part 31 also includes a connecting member, the two ends of which are connected to the second air outlet pipe 33 and the second connecting pipe 34, respectively. The connecting member passes through the oblong hole 323, and its position within the oblong hole 323 is adjustable. The oblong hole 323 allows the connecting member to move within a certain range, flexibly adapting to different tool magazine structures and working conditions, thus improving the versatility and adaptability of the device. Simultaneously, adjusting the angle and position of the second air outlet pipe 33 ensures that the airflow accurately covers the target area, achieving fine-tuning of the position of the second air outlet pipe 33 relative to the housing 11 and improving the purging accuracy.

[0049] Specifically, the second vent pipe 33 is inclined downward from the waist-shaped hole 323, that is, inclined toward the surface of the housing 11, so as to ensure that the gas is blown onto the surface of the housing 11.

[0050] In this embodiment, the waist-shaped hole 323 extends vertically to adjust the height of the connecting member.

[0051] In other embodiments, the waist-shaped hole 323 may extend in other directions as needed for purging.

[0052] like Figure 7 As shown, the connecting component includes an air inlet connector 35 and a nut 36. The air inlet connector 35 has a snap-fit ​​section and a threaded section connected in sequence. The threaded section passes through a waist-shaped hole 323, and its end communicates with the second air outlet pipe 33. The snap-fit ​​section is located on the side of the second section 322 away from the threaded section and abuts against the second section 322. Its end communicates with the second connecting pipe 34. One end of the nut 36 is threadedly connected to the threaded section and abuts against the second section 322. The nut 36 and the snap-fit ​​section cooperate to fix the position of the air inlet connector 35 within the waist-shaped hole 323. The other end of the nut 36 is threadedly connected to the second air outlet pipe 33. By designing the air inlet connector 35 and the nut 36, a stable connection between the second air outlet pipe 33 and the second connecting pipe 34 is achieved, while providing the convenience of fine-tuning the position. Loosening the nut 36 can adjust the position of the air inlet connector 35 in the oblong hole 323. Tightening the nut 36 and the threaded section makes the nut 36 and the snap-fit ​​section abut and clamp with the second section, thus fixing the position of the connecting part.

[0053] In this embodiment, the first segment 321 is also provided with a strip hole, which can be adjusted and fixed to the housing 11 by fasteners.

[0054] Furthermore, the tool magazine includes multiple second purging mechanisms 30, and the second air inlets 301 of the multiple second purging mechanisms 30 are respectively connected to multiple second air outlets 402.

[0055] In this embodiment, the tool magazine also includes a second opening and a second rotating door 15. The second opening is disposed on the housing 11 and extends from the top of the housing 11 to the side wall. The second rotating door 15 can rotate relative to the housing 11 to open or close the second opening.

[0056] In this embodiment, the tool magazine includes four second purging mechanisms 30. Two of these mechanisms are used to purge the outer surface of the top of the housing 11 near the first opening, and the height of the second vent pipe 33 is higher than the height of the first rotating door to avoid interference between the first rotating door and the second vent pipe 33 when the door rotates. The other two mechanisms are used to purge the outer surface of the top of the housing 11 near the second opening. Each of the four second purging mechanisms 30 is connected to one of the four second vent holes 402. The remaining second vent holes 402 are sealed with plugs 42 to prevent air leakage.
