DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-6 , the present invention provides a base for a numerical control machine tool, including a bottom plate 1 and a support base 2. The support base 2 is fixed to the top surface of the bottom plate 1, and further includes:

[0029] Ventilation holes 4. A plurality of ventilation holes 4 are provided and evenly opened on the top surface of the support base 2. There is a connection between the bottom plate 1 and the support base 2. A reciprocating lead screw 12 is rotatably connected to the inner wall of the support base 2. A first drive motor 3 coaxially connected to the reciprocating lead screw 12 is fixedly installed on the outer surface of the support base 2. A movable seat 14 is sleeved on the outer surface of the reciprocating lead screw 12 by a thread. An installation frame 19 is provided at the upper end of the movable seat 14. A second drive motor 15 is fixedly installed inside the installation frame 19. A fan blade 16 is fixed to the output end of the second drive motor 15. A bottom block 22 is fixed to the bottom surface of the installation frame 19. Shafts 20 are fixed to both sides of the bottom block 22. Fixed blocks 21 are fixedly installed on both sides of the top surface of the movable seat 14. The mutually remote ends of the two shafts 20 are respectively rotatably connected to the surfaces of the fixed blocks 21. An angle adjustment mechanism is provided on the outer surface of the installation frame 19;

[0030] A slider 13. The slider 13 is fixed to the bottom surface of the movable seat 14. A fixed rod 11 is fixed to the inner wall of the support base 2. The fixed rod 11 movably penetrates through the slider 13. A filter plate 5 is inserted into one side of the support base 2. Support rods 28 are fixedly installed on both sides of the movable seat 14. Vibration dust removal mechanisms cooperating with the filter plate 5 are provided at the mutually remote ends of the two support rods 28.

[0031] It is worth noting that when the first drive motor 3 drives the reciprocating lead screw 12 to rotate, the slider 13 is limited by the fixed rod 11, so as to keep the movable seat 14 moving horizontally back and forth under the rotation of the reciprocating lead screw 12.

[0032] Furthermore, as shown in Figure 3 、 Figure 4 and Figure 5 , it is worth specifically stating that the angle adjustment mechanism includes:

[0033] The connecting block 23 is fixed to the outer surface of the mounting bracket 19. A movable rod 24 is fixed to one side of the connecting block 23. A rectangular ring 25 is movably sleeved on the outer surface of the movable rod 24. A moving rod 26 is fixed to one side of the rectangular ring 25. A U-shaped mounting block 17 is fixed to the end of the moving rod 26. A roller 18 is rotatably connected to the inner side of the U-shaped mounting block 17. A fixing plate 8 is fixed to the inner wall of the support base 2. An arc-shaped convex block 9 that cooperates with the roller 18 is fixed to one side of the fixing plate 8;

[0034] The limiting rod 10 is fixed to the inner wall of the support base 2. A movable hole 27 is formed in one side of the moving rod 26. The limiting rod 10 movably penetrates through the movable hole 27.

[0035] It should be noted that the moving rod 26 is limited by the cooperation of the limiting rod 10 and the movable hole 27, so as to maintain the stability of the roller 18 during rolling. The setting of the movable hole 27 provides a moving space for the horizontal movement of the moving rod 26.

[0036] Furthermore, as Figure 4 and Figure 6 shown, specifically, the vibration dust removal mechanism includes:

[0037] There are two pressing plates 33, which are respectively fixed to the ends of the two support rods 28. Fixed frames 29 are fixed to both sides of the inner wall of the support base 2. A support rod 30 is fixed to the inner side of the fixed frame 29. A movable block 34 is movably sleeved on the outer surface of the support rod 30. A spring 31 is movably sleeved on the outer surface of the support rod 30. The top end of the spring 31 is fixed to the bottom surface of the movable block 34. The bottom end of the spring 31 is fixed to the surface of the fixed frame 29. A push rod 35 is fixed to the bottom surface of the movable block 34. A clapper 36 is fixed to the bottom end of the push rod 35. A runner 32 is rotatably connected to one side of the movable block 34;

[0038] There are multiple arc-shaped grooves, which are respectively and evenly formed on the bottom surface of the pressing plate 33. The runner 32 cooperates with the arc-shaped grooves.

[0039] Furthermore, as Figure 1 shown, specifically, a clamping block 6 is rotatably connected to the outer surface of the support base 2. The clamping block 6 is clamped with the side edge of the filter plate 5. The filter plate 5 in the support base 2 can be limited by the clamping block 6 to maintain the stability of the filter plate 5. At the same time, it provides convenience for the disassembly and assembly of the filter plate 5; A holding rod 7 is fixed to the outer surface of the filter plate 5. The holding rod 7 is convenient for holding the filter plate 5; Two one-way exhaust valves are fixedly installed on the outer surface of the support base 2. The air flow in the support base 2 is maintained through the one-way exhaust valves.

[0040] Furthermore, as Figure 2As shown in the figure, it is worth specifically explaining that the support base 2 is connected to the bottom plate 1. Guide plates are fixed on both sides of the inner wall of the support base 2, which facilitates the falling of dust and impurities, and reduces the accumulation of dust and impurities at the edge of the inner wall of the support base 2 after they fall.

[0041] This solution has the following working process: The CNC machine tool is placed on the ground more stably through the base. During the machining process of the machine tool, more heat is easily generated inside, and the heat is not easily dissipated. As a result, more heat will accumulate after the machine tool works for a long time, which will affect the service life of the machine tool. The second driving motor 15 drives the fan blade 16 to rotate, and the rotating fan blade 16 accelerates the air flow at the bottom of the CNC machine tool, thereby dissipating heat from the bottom of the machine tool. Then, the first driving motor 3 drives the reciprocating lead screw 12 to rotate, thereby driving the movable seat 14 to reciprocate horizontally in the support base 2, increasing the heat dissipation area of the fan blade 16. When the movable seat 14 moves horizontally, it drives the movable rod 26 to move horizontally through the connecting block 23 and the movable rod 24, and the movable rod 26 is limited by the limiting rod 10, thereby driving the roller 18 to roll on the surfaces of the fixed plate 8 and the arc-shaped convex block 9. When the roller 18 rolls, the movable rod 26 is pushed and pulled, so that the rectangular ring 25 pulls the movable rod 24, thereby pulling the mounting frame 19 to swing left and right, and further making the fan blade 16 swing left and right when moving horizontally, further increasing the heat dissipation area of the fan blade 16 and improving the heat dissipation efficiency of the fan blade 16.

[0042] The air entering the support base 2 is filtered by the filter plate 5, reducing the dust and impurities from falling onto the surface of the fan blade 16 and maintaining the rotation efficiency of the fan blade 16. When the movable seat 14 reciprocates horizontally, the pressing plate 33 is driven to reciprocate horizontally through the support rod 28. When the pressing plate 33 passes through the runner 32, the pressing plate 33 presses the runner 32. When the runner 32 is pressed, the push rod 35 is pushed downward through the movable block 34, causing the clapper 36 to move downward and flap the filter plate 5. When the runner 32 is located in the arc-shaped groove, the clapper 36 resets under the elastic force of the spring 31. Thus, when the pressing plate 33 passes through the runner 32, the clapper 36 continuously flaps the filter plate 5, thereby flapping off the dust and impurities attached to the bottom surface of the filter plate 5 and achieving the effect of dust removal.

[0043] According to the above working process, it can be seen that through the mutual cooperation of the first driving motor 3, the fan blade 16, the second driving motor 15, the reciprocating lead screw 12 and the angle adjustment mechanism, a fan blade 16 realizes multi-angle heat dissipation for the bottom of the machine tool, improves the heat dissipation effect of the machine tool, and reduces the accumulation of heat in the machine tool. The air entering the support base 2 is filtered by the filter plate 5, reducing the dust and impurities from falling onto the surface of the fan blade 16 and maintaining the rotation efficiency of the fan blade 16. Through the setting of the vibration dust removal mechanism, the movable seat 14 drives the pressing plate 33 to move horizontally, and then through the cooperation of the arc-shaped groove and the runner 32, the clapper 36 continuously flaps the filter plate 5, achieving the effect of removing impurities from the filter plate 5.

[0044] The first drive motor 3 and the second drive motor 15 can be purchased on the market. The first drive motor 3 and the second drive motor 15 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the specification.

[0045] As described above, it is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claimed rights.

[0046] Finally: The above description is only the preferred embodiment of the present utility model and is not used to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
