Description

Technical Field

[0001] This utility model relates to the field of disc tool magazine technology for machining centers, and in particular to a disc tool magazine for five-axis machining centers with a dust removal mechanism. Background Technology

[0002] When changing tools in a machining center, cutting fluid adheres to the surface of the tools. After the tools are replaced and placed in the tool magazine, dust easily adheres to their surfaces. Once the cutting fluid dries, it can cause dirt to accumulate on the tool holder. Since tool positioning mainly relies on the tapered part of the tool holder, dirt can affect the positioning of subsequent tools. Dirt can also stick to the tool tip and the tool holder's positioning and clamping positions, contaminating the tool tip. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a disc-type tool magazine for a five-axis machining center with a dust removal mechanism.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a disc-type tool magazine for a five-axis machining center with a dust removal mechanism, comprising a support plate and a rotating tool disc rotatably disposed above the support plate, and further comprising a dust removal mechanism, wherein the dust removal mechanism includes:

[0005] The cleaning component is arc-shaped and positioned on at least one side of the tool movement trajectory on the rotating cutter head. It is coaxial with the rotation axis of the rotating cutter head and has internal flow channels. Multiple nozzles communicating with the flow channels are spaced apart on the side near the movement trajectory.

[0006] The control valve is connected to the air source at one end and to the cleaning component at the other end; it is configured to work in conjunction with the rotating cutter disc and to alternate between a closed state and an open state when the rotating cutter disc rotates.

[0007] Furthermore, the cleaning component comprises two parts, with the nozzles on the two cleaning components arranged alternately.

[0008] Furthermore, it also includes a top plate spaced apart from the support plate, and the cleaning component is detachably disposed on the lower surface of the top plate.

[0009] Furthermore, the cleaning component includes an upper surface that seals with the lower surface of the top plate, and the upper surface is provided with an arc-shaped groove, the nozzle being connected to the arc-shaped groove.

[0010] Furthermore, the control valve is connected to the support plate, and the rotating cutter head is connected to a trigger. The trigger has multiple protrusions evenly spaced around the axis of the rotating cutter head.

[0011] Furthermore, the control valve is a mechanical valve, with a swing arm rotatably mounted at one end of the mechanical valve near the trigger element. A rolling element is provided at the end of the swing arm, and the middle area of ​​the swing arm corresponds to the valve stem of the mechanical valve.

[0012] Furthermore, it also includes a distribution valve, the air inlet of which is connected to a mechanical valve, and the cleaning component is connected to the distribution valve.

[0013] Furthermore, a rotating component is rotatably mounted on the support plate, the rotating cutter head is mounted on the rotating component, and the triggering component is an annular component that is detachably mounted on the rotating component.

[0014] This utility model discloses a disc-type tool magazine for a five-axis machining center with a dust removal mechanism, which has the following advantages compared with the prior art: When the rotating tool disc is not rotating, the control valve is in a closed state, and gas cannot pass through the control valve at this time. When changing tools, as the rotating tool disc rotates, the control valve is opened once for each tool position. When the control valve is opened, compressed gas is delivered to the cleaning component through the control valve and flows out from the nozzle on the cleaning component. The airflow sprays and cleans the tools that are clamped on the rotating tool disc. On the one hand, it can clean the dust attached to the tools. On the other hand, when the newly replaced tools pass through the nozzle, the airflow can also clean the cutting fluid on the surface of the newly replaced tools, thereby improving the cleanliness of the tools and reducing the probability of tool contamination, thus reducing problems caused by contamination.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please refer to Figures 1-6 This utility model provides a disc-type tool magazine for a five-axis machining center with a dust removal mechanism, including a support plate 10 and a rotating tool disc 13 rotatably disposed above the support plate 10, and also includes a dust removal mechanism, which includes:

[0028] The cleaning component is arc-shaped and positioned on at least one side of the tool movement trajectory on the rotating cutter head 13. It is coaxial with the rotation axis of the rotating cutter head 13 and has a flow channel inside. Multiple nozzles 33 communicating with the flow channel are spaced apart on the side near the movement trajectory.

[0029] The control valve is connected to the air source at one end and to the cleaning component at the other end; it is configured to work in conjunction with the rotating cutter disc 13 and to alternate between a closed state and an open state when the rotating cutter disc 13 rotates.

[0030] For details, please refer to Figures 1-6The central disc-type tool magazine includes a support plate 10. A support housing 12 is provided on the upper surface 321 of the support plate 10. A drive motor (not shown in the figure) is installed inside the support housing 12. A rotating component 15 is rotatably mounted on the top of the support housing 12 about a vertical axis. The rotating component 15 is driven and connected to the drive motor. A bearing is provided on the top of the rotating component 15. A bearing seat 14 is fitted around the bearing. The bearing seat 14 is detachably and fixedly connected to the top plate 11. The bearing seat 14 is coaxially arranged with the through hole 110 on the top plate 11. A fixing plate 120 is also detachably and fixedly mounted on the top of the support housing 12. A control valve is mounted on the fixing plate 120. This application includes a cleaning component, which is connected to the control valve through an air pipe. The air inlet of the control valve is connected to the air... When the source is connected and the cutting head 13 is not rotating during operation, the control valve is in a closed state, and gas cannot pass through the control valve at this time. When changing tools, as the cutting head 13 rotates, the control valve is opened once for each tool position. When the control valve is opened, compressed gas is delivered to the cleaning component through the control valve and flows out from the nozzle 33 on the cleaning component. The airflow sprays and cleans the tool that is clamped on the cutting head 13. On the one hand, it can clean the dust attached to the tool. On the other hand, when the tool that has just been replaced passes through the nozzle 33, the airflow can also clean the cutting fluid on the surface of the tool that has just been replaced, thereby improving the cleanliness of the tool and reducing the probability of tool contamination, thus reducing problems caused by contamination.

[0031] Furthermore, as a preferred embodiment, refer to Figures 2-5 The cleaning component includes two parts, and the nozzles 33 on the two cleaning components are arranged alternately.

[0032] Specifically, as a preferred embodiment, the cleaning components include two components disposed on both sides of the tool movement trajectory on the rotating cutter head 13, namely a first cleaning component 31 and a second cleaning component 32. Both the first cleaning component 31 and the second cleaning component 32 are provided with nozzles 33. With this arrangement, airflow can be sprayed to clean the tool in both directions, thereby improving the cleaning effect.

[0033] Preferred, Reference Figure 5 , Figure 6 The nozzle 33 has a flat nozzle at the spray end, and the length of the flat nozzle is set in the vertical direction. This setting can increase the outflow speed of the airflow and ensure the vertical cleaning area, thereby improving the cleaning effect.

[0034] Furthermore, as a specific implementation method, refer to Figures 1-6 It also includes a top plate 11 spaced apart from the support plate 10, and the cleaning component is detachably disposed on the lower surface of the top plate 11.

[0035] As a preferred embodiment, the cleaning component is an arc-shaped rigid component, which can be made of materials such as aluminum alloy or plastic. A threaded hole 322 is provided on the upper surface 321 of the cleaning component, and a through hole 110 corresponding to the threaded hole 322 is provided on the top plate 11. A screw is used to pass through the through hole 110 and connect to the threaded hole 322 to achieve the purpose of fixing the cleaning component. With this setting, the original top plate 11 of the tool magazine can be used to fix the cleaning component, and the internal space of the tool magazine can be used in a reasonable way. The whole layout is simple and reasonable.

[0036] Furthermore, as a preferred embodiment, refer to Figure 6 The cleaning component includes an upper surface 321 that seals with the lower surface of the top plate 11. The upper surface 321 has an arc-shaped groove 323, and the nozzle 33 communicates with the arc-shaped groove 323. Specifically, the upper surface 321 of the cleaning component is flush with the plane, and the arc-shaped groove 323 is formed on the upper surface 321. Threaded holes 322 are provided at both ends and on both sides of the arc-shaped groove 323. When connected to the top plate 11, the upper surface 321 abuts and seals with the lower surface of the top plate 11 when the cleaning component is fixed with screws. This forms a flow channel between the arc-shaped groove 323 and the area corresponding to the lower surface of the top plate 11 and the arc-shaped groove 323. This design simplifies the processing difficulty of the flow channel, making the cleaning component easier to manufacture.

[0037] Furthermore, as a specific implementation method, refer to Figures 1-3 A distribution valve 2 is also provided on the support plate 10. When there are two cleaning components, the first cleaning component 31 is provided with a first connector 310, which is connected to the distribution valve 2 through a first pipe 21. The second cleaning component 32 is provided with a second connector 320, which is connected to the distribution valve 2 through a second pipe 22. The air inlet of the distribution valve 2 is connected to the control valve through a third pipe 23.

[0038] Furthermore, as a specific implementation method, refer to Figures 4-10 The control valve is connected to the support plate 10, and the rotating cutter head 13 is connected to a trigger 34. The trigger 34 has a plurality of protrusions 340 evenly spaced around the axis of the rotating cutter head 13.

[0039] Specifically, a support housing 12 is provided above the support plate 10. A fixing plate 120 is detachably fixed to the upper end of the support housing 12. A rotating component 15 is rotatably disposed at the upper end of the support housing 12. A drive motor is disposed inside the support housing 12 and connected to the rotating component 15 to drive the rotating component 15. The rotating cutter head 13 is horizontally disposed and detachably fixed to the rotating component 15 to drive the rotating cutter head 13. In this application, from top to bottom, the rotating component 15 includes two steps. The rotating cutter head 13 is connected to the upper step. The trigger component 34 is an annular plate structure that cooperates with the support surface 150 of the lower step and is locked by screws. The protrusion 340 is disposed on the outer circumferential surface of the annular plate and includes a cam surface. When the rotating cutter head 13 rotates, it drives the trigger component 34 to rotate synchronously. The cam surface alternately presses the control valve, thereby realizing the alternating opening of the control valve.

[0040] Furthermore, as a specific implementation method, refer to Figures 8-10 The control valve is a mechanical valve 35. A swing arm 350 is rotatably provided at one end of the mechanical valve 35 near the trigger 34. A rolling element 351 is provided at the end of the swing arm 350. The middle area of ​​the swing arm 350 corresponds to the valve stem 355 of the mechanical valve 35.

[0041] Specifically, the control valve includes a mechanical valve body 35, which has a valve stem 355. The mechanical valve 35 uses a valve body commonly used in existing technology and is normally in a closed state. A base plate 356 is detachably connected to the bottom of the valve body, and the base plate 356 is connected to the fixed plate 120. One end of the valve stem 355 on the valve body is located near the trigger 34, and a swing arm 350 is rotatably mounted at the end. A rolling element 351 is provided at the end of the swing arm 350. When the rotating tool disc 13 of the tool magazine stops rotating, the rolling element... 351 corresponds to the two adjacent protrusions 340. At this time, the mechanical valve 35 is in the closed state. When the rotating cutter head 13 rotates, the protrusions 340 can push the swing arm 350 to swing when they squeeze the rolling element 351, and squeeze the valve stem 355 to open the mechanical valve 35. The mechanical valve 35 includes a third air inlet 352 and a fourth air inlet 353. The third air inlet 352 is connected to the third pipe 23, and the fourth air inlet 353 is connected to the fourth pipe 24. The other end of the fourth pipe 24 is connected to the air source.

[0042] Furthermore, as a specific implementation, it also includes a distribution valve 2, the air inlet end of which is connected to the mechanical valve 35, and the cleaning component is connected to the distribution valve 2.

[0043] Furthermore, as a specific implementation, a rotating member 15 is rotatably disposed on the support plate 10, the rotating cutter head 13 is disposed on the rotating member 15, and the trigger member 34 is an annular member that is detachably disposed on the rotating member 15.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
