[0039] According to the above structural features of the application, the embodiments of the application are further described:

[0040] Referring to Figures 1-2 , the embodiment provides a numerical control machine tool cooling system, comprising a spraying module 2 connected with a head 1 and a support platform 4 installed below a clamping tool 3. The clamping tool 3 is used for clamping and fixing a workpiece 5, the head 1 is connected with a milling cutter, the head 1 can drive the milling cutter to rotate and move, thereby realizing the processing of the workpiece 5. The spraying module 2 is used for spraying cooling cutting fluid to the contact position of the milling cutter and the workpiece 5, thereby cooling the milling cutter and the workpiece 5, and avoiding the problem that the milling cutter and the workpiece 5 are damaged due to high temperature.

[0041] Referring to Figure 1 With Figure 2 , the spraying module 2 comprises an extended fin 21 and a nozzle 22 capable of spraying cooling cutting fluid; the extended fin 21 is annular and is sleeved and installed at the position of the outer wall of the head 1, and the nozzle 22 is connected with the extended fin 21. The outer wall of the head 1 is fixedly connected with the extended fin 21 through bolts, and the nozzle 22 is fixedly connected with the extended fin 21 through bolts.

[0042] Referring to Figure 2 , the nozzle 22 is vertically arranged, the opening of the nozzle 22 is located at the bottom end position, and the bottom end of the nozzle 22 is inwardly inclined and points to the bottom end of the milling cutter, thereby ensuring that the cooling cutting fluid can be sprayed to the contact position of the milling cutter and the workpiece 5.

[0043] Referring to Figure 1 With Figure 3The support platform 4 is equipped with a receiving cavity for receiving cooling cutting fluid, which includes a first cavity 401 and a second cavity 402. The bottom surface of the first cavity 401 is inclined, allowing the cooling cutting fluid to flow along the bottom surface of the first cavity 401 and eventually converge at the lowest position. This also allows milling debris particles mixed in with the cooling cutting fluid to accumulate at the lowest position of the first cavity 401, thus avoiding the problem of milling debris particles accumulating in a flat manner on the bottom surface of the first cavity 401 and being difficult to clean. Vibration is unavoidable during milling; this vibration can push the milling debris particles gradually downwards along the bottom surface of the first cavity 401, further preventing the accumulation of milling debris particles.

[0044] Reference Figure 3 and Figure 5 The second cavity 402 is located at the lowest point of the bottom surface of the first cavity 401, and the bottom end of the first cavity 401 and the top end of the second cavity 402 are connected; then the cooling cutting fluid and the milling debris particles in the cooling cutting fluid can flow into the filter screen 4033 in the second cavity 402 under the action of their own weight.

[0045] Reference Figure 3 and Figure 5 A removable filter assembly 403 is installed inside the support platform 4. The lower part of the filter assembly 403 is adapted to be inserted into the second cavity 402, and the upper middle part is adapted to be attached to the inner side wall of the first cavity 401, that is, the filter assembly 403 can be stably installed inside the support platform 4.

[0046] Reference Figure 3 A riser 404 is installed inside the support platform 4. The top end of the riser 404 is connected to and communicates with the second cavity 402, and the bottom end is connected to and communicates with the storage tank 405. The storage tank 405 is connected to the nozzle 22 via a hose and a liquid pump. The storage tank 405 is placed below the support platform 4, and the bottom end of the riser 404 is inserted into the opening of the storage tank 405. The hose includes a first hose 4052 and a second hose. One end of the first hose 4052 is connected to the top of the side wall of the storage tank 405 and communicates with the inner cavity of the storage tank 405, and the other end is connected to and communicates with the liquid pump. One end of the second hose is connected to and communicates with the liquid pump, and the other end is connected to and communicates with the nozzle 22. Cooling cutting fluid is discharged into the storage tank 405 through the riser 404. The liquid pump can pump the cooling cutting fluid in the storage tank 405 into the nozzle 22. The cooling cutting fluid sprayed out by the nozzle 22 flows along the surface of the workpiece 5 and the surface of the support top plate 41 and then drips into the first cavity 401 to achieve circulation.

[0047] Reference Figure 3The support platform 4 includes a support top plate 41, a support column 42, a support base 43, and a surrounding plate 44. The support column 42 is upright, with its top end fixedly connected to the support top plate 41 (e.g., by bolts) and its bottom end fixedly connected to the support base 43 (e.g., by bolts). The surrounding plate 44 is upright and fixedly installed on the outer edge of the top surface of the support base 43 (e.g., through a sealing strip and bolts for a sealed connection). The inner wall of the surrounding plate 44 and the top surface of the support base 43 form a first cavity 401, and the bottom surface of the first cavity 401 is the inclined top surface of the support base 43. A second cavity 402 is formed at the bottom end of the inclined top surface of the support base 43, and the second cavity 402 has a concave structure.

[0048] Reference Figure 3 The bottom surface of the support column 42 is inclined and fits the inclined top surface of the support base 43, thereby improving the installation stability of the support column 42.

[0049] Reference Figure 3 and Figure 4 The support columns 42 are arranged in a matrix. Gaps are provided between adjacent support columns 42 to allow the coolant to flow. This allows the coolant to pass through the gaps between adjacent support columns 42, achieving the technical effect of flowing along the bottom surface of the first cavity 401.

[0050] Reference Figure 3 and Figure 5 The filter assembly 403 includes a support plate 4031, a hook portion 4032, and a filter screen 4033. The top end of the hook portion 4032 is fixedly connected to the top end of the support plate (e.g., by bolts), and the filter screen 4033 is fixedly connected to the bottom end of the support plate 4031 (e.g., by bolts). The hook portion 4032 and the filter screen 4033 are respectively located on the left and right sides of the support plate 4031. The hook portion 4032 points outward and can be fastened to the top end of the enclosure plate 44, and the filter screen 4033 points inward and can be inserted into the second cavity 402.

[0051] Reference Figure 3 and Figure 5 The upright support plate 4031 is in the shape of a straight plate and can be adapted and fitted to the inner side wall of the surrounding plate 44, thereby avoiding the problem of the upright support plate 4031 occupying too much internal space of the first cavity 401.

[0052] Reference Figure 5The vertical section of the hook portion 4032 is in the shape of the letter "7", and the hook portion 4032 can be fitted and clamped with the top end of the coaming 44. The height of the hook portion 4032 is higher than that of the filter screen 4033 and is hung on the top end of the coaming 44, so the surface of the hook portion 4032 will not adhere to the cooling cutting fluid, and the user can conveniently lift the entire filter assembly 403 by grabbing the hook portion 4032, or conveniently install the filter assembly 403 in the support platform 4, and avoid the user's fingers from being contaminated by the cooling cutting fluid.

[0053] With reference to Figure 5 The hook portion 4032 is provided with a hooking portion 40321 and a hooking portion 40322. The hooking portion 40321 is provided with a plurality of hooking holes 403211, and the hooking portion 40322 is provided with a plurality of hooking holes 403222. The hooking holes 403211 and the hooking holes 403222 are arranged in a staggered manner. Figure 6 The filter screen 4033 includes an edge frame 40331 and a screen body 40332. The edges of the screen body 40332 are fixedly connected to the edge frame 40331 (for example, by a pressing strip and a bolt). The edge frame 40331 is in the shape of a U and can be fitted and clamped with the inner wall of the second cavity 402, so as to fix the bottom end of the filter assembly 403, thereby avoiding the problem that the filter assembly 403 is bounced out due to vibration (which is inevitable during the milling process).

[0054] With reference to Figure 5 The edge frame 40331 is provided with a limiting protrusion 40333 at the end away from the vertical support plate 4031, and the inner side wall of the second cavity 402 is provided with a limiting groove capable of fitting and clamping the limiting protrusion 40333. Figure 7 The limiting protrusion 40333 is fixedly connected to the edge frame 40331 (for example, by integral fixing or by bolt fixing). After the limiting protrusion 40333 is clamped with the limiting groove, the installation stability of the bottom end of the filter assembly 403 can be further improved, thereby avoiding the problem that the filter screen 4033 is detached from the second cavity 402, and further avoiding the problem of filter failure.

[0055] With reference to Figure 1 The clamping tool 3 is arranged at the top surface position of the support top plate 41, and the clamping tool 3 and the support top plate 41 are detachably connected by a bolt. Figure 3 The clamping tool 3 is a conventional prior art in the industry, and the specific structure will not be described again.

[0056] With reference to Figure 3 During the process that the cooling cutting fluid flows into the vertical pipe 404 through the second cavity 402, the filter assembly 403 can filter out large-diameter milling chip particles in the cooling cutting fluid, and the user can conveniently take out the filter assembly 403 and clean the inside of the milling chip particles.

[0057] With reference to Figure 8The storage box 405 is provided with a vertical partition plate 4051, the vertical partition plate 4051 divides the inner cavity of the storage box 405 into a first containing cavity 40501 and a second containing cavity 40502, the first containing cavity 40501 and the second containing cavity 40502 are only communicated at the bottom; the vertical pipe 404 is communicated with the first containing cavity 40501, and the first hose 4052 is communicated with the second containing cavity 40502. The cooling cutting fluid is injected into the storage box 405 through the vertical pipe 404, then flows downward along the first containing cavity 40501 to the bottom of the storage box 405, and further flows upward along the second containing cavity 40502 to the position of the first hose 4052. The base 6 and the liquid pump are placed on the workbench. The top surface of the base 6 is provided with a permanent magnet 61 fixed by bolts. During the upward flow of the cooling cutting fluid, the small particle size milling debris particles mixed in the cooling cutting fluid are deposited at the bottom of the storage box 405 under the action of gravity and magnetic force, so as to avoid the problem that the small particle size milling debris particles enter the liquid pump and damage the liquid pump. The permanent magnet 61 is made of a permanent magnet material (for example, an aluminum-nickel-cobalt permanent magnet alloy, an iron-chromium-cobalt permanent magnet alloy, a permanent magnet ferrite, etc.). The user can conveniently pour out the milling debris particles and residual cooling cutting fluid in the storage box 405 after lifting the storage box 405 from the permanent magnet 61, so as to realize the recycling of the milling debris particles. The storage box 405 is made of a non-magnetic plastic material (for example, PP plastic, ABS plastic, etc.).

[0058] The support platform 4 is placed on the pedestal, the pedestal supports the support platform 4 at a fixed height, and the storage box 405 is placed on one side of the pedestal, so that the problem that the support platform 4 presses the storage box 405 can be avoided, and the problem that the storage box 405 is pressed and damaged can be avoided. The pedestal is fixedly connected to the workbench by bolts. The workbench is fixedly provided with a support frame, and the support frame is connected with the machine head 1 through a mechanical arm or an xyz three-axis driving structure, so as to realize the movement of the machine head 1 and realize milling.

[0059] The utility model discloses simple structure, reliable function, and the support platform 4 is provided with the containing cavity for receiving cooling cutting fluid, and the bottom surface of the first cavity 401 is inclined, so that the cooling cutting fluid can flow along the bottom surface of the first cavity 401 and finally gather at the lowest position, and the milling debris particles mixed in the cooling cutting fluid can gather at the lowest position of the first cavity 401, thereby avoiding the problem that the milling debris particles accumulate in the form of flat laying on the bottom surface of the first cavity 401 and are difficult to clean.
