[0022] A schematic grinder cooling device, referring to Figures 1 to 4 A grinder cooling device according to a preferred embodiment of the present application comprises a base 10, a clamping module 20, a grinding module 30, and a cooling mechanism 40.

[0023] It is noted that, as Figure 1 and Figure 2As shown, the clamping module 20, the grinding module 30 and the cooling mechanism 40 are all mounted on the machine base 10, the workpiece is clamped rotatably by the clamping module 20, and the workpiece is ground by the grinding module 30; in addition, the cooling mechanism 40 comprises a spray gun 401, a liquid-particle separation mechanism 402 and a liquid storage tank 403, the spray gun 401 is arranged on the grinding module 30, the liquid inlet of the liquid storage tank 403 is communicated with the liquid-particle separation mechanism 402, the liquid outlet of the liquid storage tank 403 is communicated with the spray gun 401, the machine base 10 has a material dropping port 101, the material dropping port 101 is arranged between the clamping module 20 and the grinding module 30, the liquid-particle separation mechanism 402 is located below the material dropping port 101, and the liquid-particle separation mechanism 402 comprises four sieve plates 4021, and each sieve plate 4021 is provided with a first filter screen 40211.

[0024] It should be noted that when the grinding module 30 cuts the workpiece, the spray gun 401 sprays the cooling liquid and carries away the metal particles, and passes through the material dropping port 101 together and falls on a sieve plate 4021 below, by arranging the first filter screen 40211 on the sieve plate 4021, the cooling liquid passes through the first filter screen 40211 and finally returns to the liquid storage tank 403, and the metal particles in the cooling liquid are retained in the first filter screen 40211, so that the freshly ground surface is not scratched when the cooling liquid contacts the workpiece again.

[0025] However, after long-term filtering, the first filter screen 40211 on the sieve plate 4021 retains too many metal particles, and it is difficult for the cooling liquid to pass through the first filter screen 40211, in the prior art, one first filter screen 40211 is arranged and needs to be replaced in time, but in high-intensity continuous processing, if the first filter screen 40211 is blocked during processing, on-site replacement of the first filter screen 40211 will affect production efficiency. In the embodiment of the application, four sieve plates 4021 are arranged, when one sieve plate 4021 is blocked, the sieve plate 4021 is rotated by a predetermined angle, and another new sieve plate 4021 is directed towards the material dropping port 101, so that the first filter screen 40211 is switched in time during processing; however: when the new sieve plate 4021 is directed towards the material dropping port 101, the metal particles on the original sieve plate 4021 that carries the metal particles or residual cooling liquid residue, if the metal particles are directly poured, the residual cooling liquid will be collected.

[0026] In view of this, to realize the first filter screen 40211 on the screening disc 4021 can make the screening disc 4021 rotate when it is blocked, and the residual cooling liquid in the metal particles can be separated out and then collected uniformly, as shown in Figures 1 to 3 The liquid-particle separation mechanism 402 also includes a first rotating shaft 4022, a draining baffle 4023 and a collection box 4024. The four screening discs 4021 are arranged in a ring array around and connected to the first rotating shaft 4022. When the metal particles accumulate and make it difficult for the cooling liquid to pass through, the first rotating shaft 4022 rotates by a predetermined angle, and the residual cooling liquid in the metal particles is drained through the draining baffle 4023 located on one side of the liquid-particle separation mechanism 402, and after the first rotating shaft 4022 rotates by a predetermined angle again, the drained metal particles fall into the collection box 4024.

[0027] More specifically, to realize that the cooling liquid can flow into the liquid storage tank 403 after passing through the first filter screen 40211, and to realize the separation of metal debris and the residual cooling liquid therein after the screening disc 4021 rotates by a predetermined angle, as shown in Figure 1 and Figure 3 The first rotating shaft 4022 has four first channels 4025 arranged in a ring array. The first channels 4025 communicate with the liquid inlet of the liquid storage tank 403. The first rotating shaft 4022 is rotatably installed on the machine base 10. The collection box 4024 is located at one end of the screening disc 4021 away from the material drop opening 101. The disc opening of one of the screening discs 4021 faces the material drop opening 101. The disc opening of another of the screening discs 4021 opposite to the one faces the collection box 4024. The draining baffle 4023 is provided on one side of one of the screening discs 4021 between the two screening discs 4021. The draining baffle 4023 is vertically arranged and covers the disc opening of the screening disc 4021. The draining baffle 4023 is provided with a second filter screen 40231.

[0028] In addition, as shown in Figure 1 and Figure 3As shown, each of the screening discs 4021 has a concave arc cavity 40212, and both ends of the concave arc cavity 40212 have convex arc profiling baffles 40213 arranged vertically, the water draining baffles 4023 are circular arc-shaped, and the inner arc surface of the water draining baffles 4023 is equal to the radius size from the outer edge of the convex arc profiling baffles 40213 to the central axis of the first rotating shaft 4022. In addition, the four screening discs 4021 are arranged in a ring array and fixedly connected in sequence between the end and the end, the spacing between the two end portions of each of the screening discs 4021 to the central axis of the first rotating shaft 4022 is equal to the radius size of the inner arc surface of the water draining baffles 4023 to the central axis of the first rotating shaft 4022, and the adjacent two screening discs 4021 have arc surfaces 40214 at the connection, and the arc surfaces 40214 are in contact or separated from the inner arc surface of the water draining baffles 4023 when the screening discs 4021 rotate.

[0029] It should be noted that when the cooling liquid falls into the concave arc cavity 40212, it passes through the first filter screen 40211 and flows into the corresponding first channel 4025 on the first rotating shaft 4022 below, and flows into the liquid storage tank 403 along the first channel 4025; when the first filter screen 40211 on the screening disc 4021 is blocked, the first rotating shaft 4022 is rotated by 90°, at this time the screening disc 4021 collecting metal particles is covered by the draining baffle 4023, and since the screening disc 4021 and the draining baffle 4023 are vertically arranged, the metal particles on the screening disc 4021 are stacked at one end of the concave arc cavity 40212 under the action of gravity, and when the first rotating shaft 4022 is rotated by 90°, the other screening disc 4021 without collecting metal particles or with a small amount of collecting metal particles is directed towards the material falling port 101, realizing screening out metal particles in the cooling liquid within a period of time, and in this period of time, the residual cooling liquid in the metal particles on the vertically arranged screening disc 4021 passes through the second filter screen 40231, realizing draining out of the residual cooling liquid in the metal particles, realizing separation of the cooling liquid and the metal particles, when the first filter screen 40211 on the newly switched screening disc 4021 is also blocked, the first rotating shaft 4022 is rotated by 90° again, and the newly switched screening disc 4021 repeats the water draining process, and the screening disc 4021 that has been drained of water and contains metal particles is directed towards the collecting tank 4024 after the rotating shaft is rotated by 90° again, and there is no obstruction between the concave arc cavity 40212 and the collecting tank 4024, so that the metal particles drained of water fall into the collecting tank 4024 under the action of gravity, when the metal particles in the collecting tank 4024 are collected to a predetermined degree, they can be taken out and pressed into iron cakes by an external pressure mechanism and recycled, and by arranging the draining baffle 4023, the metal particles collected into the collecting tank 4024 are prevented from having a high liquid content. It can be seen that compared with the prior art, the present application has the advantages of being able to filter metal particles in the cooling liquid, being able to switch in time when the metal particles block the filter screen, and being able to collect metal particles.

[0030] Further, in order to realize that when the first filter screen 40211 is blocked, the first rotating shaft 4022 is rotated by 90°, Figure 1 and Figure 4As shown, the first rotating shaft 4022 rotates circumferentially, the liquid-particle separation mechanism 402 further comprises a plurality of second rotating shafts 4026, a displacement sensor 4027 and a first rotary drive device 4028, each of the first channels 4025 is rotatably installed with a second rotating shaft 4026, the second rotating shaft 4026 is provided with a plurality of rotating leaves 40261, one end of the second rotating shaft 4026 is provided with a cam portion 40262, and the lower side of the cam portion 40262 is provided with the displacement sensor 4027, the lead wire of the displacement sensor 4027 passes through the center of the first rotating shaft 4022 and is electrically connected with the controller of the grinding machine, and the output shaft of the first rotary drive device 4028 is fixedly connected with the first rotating shaft 4022.

[0031] It should be noted that when the grinding machine is running and processing workpieces, the spray gun 401 always sprays cooling liquid, so when the first filter screen 40211 is not blocked, the cooling liquid always passes through the first filter screen 40211 and flows into the first channel 4025, and impacts the rotating leaf 40261, and makes the second rotating shaft 4026 rotate circumferentially, and drives the cam portion 40262 to rotate circumferentially, and makes the displacement sensor 4027 obtain a periodically changing distance parameter and continuously transmit to the controller of the grinding machine, and when the first filter screen 40211 is blocked, it is difficult for the cooling liquid to pass through the first filter screen 40211 and flow into the first channel 4025 and impact the rotating leaf 40261, so at this time the second rotating shaft 4026 does not rotate circumferentially, and at this time the displacement sensor 4027 is difficult to continuously transmit an electrical signal to the controller of the grinding machine, so at this time the controller of the grinding machine sends an electrical signal to the first rotary drive device 4028, and makes the first rotating shaft 4022 rotate circumferentially and rotate by 90°, so that when the first filter screen 40211 is blocked, the first rotating shaft 4022 rotates circumferentially.

[0032] Further, in order to realize the recovery of the residual cooling liquid, as shown in the drawings, Figure 3 As shown, the liquid-particle separation mechanism 402 further comprises a second channel 4029, one end of the second channel 4029 is directed to the second filter screen 40231, and the other end is in communication with the liquid storage tank 403.

[0033] Further, since the width dimension of the first rotating shaft 4022 is smaller than the width dimension of the screening disc 4021, in order to increase the area of the first filter screen 40211, so that the cooling liquid passing through the first filter screen 40211 can completely flow into the first channel 4025, as shown in the drawings, Figure 3 As shown, each of the screening discs 4021 is provided with a first water guide slope 40215 on the side close to the first rotating shaft 4022. In the embodiment of the present application, each of the screening discs is provided with two symmetrically arranged first water guide slopes 40215.

[0034] Further, to realize that the first rotating shaft 4022 rotates, the corresponding first channel 4025 can flow into the liquid storage tank 403, as shown in the figure, each first channel 4025 has a second water guide slope 40251 near one end of the liquid storage tank 403, and the liquid inlet of the liquid storage tank 403 is provided with a third water guide slope 4031, and the third water guide slope 4031 is spaced apart from the second water guide slope 40251 by a predetermined distance in the height direction.

Figure 1 It should be noted that by allowing the bottom of the clamping module 20 and the blanking port 101 to be nearly unobstructed, the cooling liquid is more easily dropped into the screening disc 4021, and the clamping module 20 is more suitable for clamping small workpieces; in addition, when installing the workpiece, the two centers are used to support the two ends of the workpiece.

[0036] Further, to facilitate the cooling liquid to fall into the screening disc 4021, as shown in the figure, the base 1022 also has two inclined surfaces 105, and the two inclined surfaces 105 are located on both sides of the blanking port 101.

[0037] Figure 2 Further, as shown in the figure, the grinding module 30 in this application also includes a grinding wheel 301 and a moving seat 302, the moving seat 302 is slidingly arranged in the width direction of the base 102, the grinding wheel 301 is rotatably installed on the moving seat 302, the spray gun 401 is arranged on the moving seat 302, and the muzzle of the spray gun 401 faces the grinding wheel 301.
