Description

Technical Field

[0001] This utility model belongs to the field of iron filings filtration technology, and relates to a centralized chip removal filtration device with a spiral flow guiding structure. Background Technology

[0002] Machine tool cutting is a core process in mechanical manufacturing. It removes material by means of the relative movement between the cutting tool and the workpiece to form the required shape and size. It is widely used in the automotive industry, aerospace mold manufacturing and other fields.

[0003] For example, patent (CN217728034U) discloses a chip removal and cleaning device for CNC machine tools, which describes that it "includes: a base, a main body fixedly installed on the top of the base, an inclined groove opened on the top of the main body, a filter screen fixedly installed inside the main body and on one side of the inclined groove, and an inclined block fixedly installed inside the main body and on one side of the filter screen. The chip removal and cleaning device for CNC machine tools provided by this utility model, due to the slope of the inclined groove, both the cutting fluid and iron chips move downwards to the filter screen. The filter screen blocks the iron chips, while the cutting fluid falls through the filter screen into the first collection box below. The collected cutting fluid can be reused. When the scraper contacts the inclined groove, due to the continued rotation of the shaft, the telescopic rod moves into the telescopic sleeve. At this time, the second spring is compressed, and the scraper contacts the filter screen, effectively scraping the iron chips on the surface of the filter screen into the second collection box, collecting the iron chips for centralized processing."

[0004] When using the above technology, the following technical problems were found in the prior art: During the process of tilting and processing iron chips, larger iron chips can be blocked by the filter screen during the cutting process, but some small amount of powdery iron chips will enter the collection box along with the cutting fluid. These powdery iron chips will not only pollute the cutting fluid, but may also cause blockage of the cutting fluid pipeline when the cutting fluid is recycled, resulting in a reduction in the cutting efficiency of the machine tool. Utility Model Content

[0005] The technical problem to be solved by this utility model is that during the process of tilting and processing iron chips, larger iron chips can be blocked by the filter screen during the cutting process, but some small amount of powdery iron chips will enter the collection box along with the cutting fluid. These powdery iron chips will not only pollute the cutting fluid, but may also cause blockage of the cutting fluid pipeline when the cutting fluid is recycled, resulting in a reduction in the cutting efficiency of the machine tool.

[0006] The present invention discloses a centralized chip removal and filtration device with a spiral flow guiding structure, comprising a storage tank; a separation pipe fixedly connected to one side of the outer side of the storage tank; a special-shaped filter screen fixedly connected to the top of the inner side of the storage tank; the special-shaped filter screen and the separation pipe being interconnected; and a spiral flow guiding component located inside the separation pipe.

[0007] The filter assembly is located at the bottom inside the storage tank; the filter assembly includes a quick-release filter element mechanism and a rotating mechanism.

[0008] The spiral guide assembly includes a servo motor; the servo motor is located on the outside of the separation pipe; a spiral guide roller is fixed to the output end of the servo motor; the spiral guide roller rotates inside the separation pipe; filter holes are formed on the inner side of the separation pipe; and a liquid guiding groove is formed on the inner wall of the separation pipe.

[0009] The filter assembly includes an isolation block; a drain outlet is located on the outside of the storage tank near the isolation block; a fixed water outlet cylinder is fixedly connected to the inside of the storage tank near the isolation block; a rotating water outlet cylinder is rotatably connected inside the fixed water outlet cylinder; a return spring is fixedly connected to the outside of the rotating water outlet cylinder; a blocking plate is fixedly connected to one end of the return spring; the blocking plate is slidably connected inside the rotating water outlet cylinder; a guide angle is provided on the outside of the blocking plate; and a high-density filter cartridge is slidably connected inside the rotating water outlet cylinder.

[0010] The rotating mechanism includes a sliding groove inside; the sliding groove is located inside the rotating water outlet cylinder; multiple sets of limiting blocks are fixed to the outside of the high-density filter cylinder; the limiting blocks slide inside the sliding groove.

[0011] The quick-release mechanism for the filter element includes a limiting groove; the limiting groove is located on the outside of the storage box; a release port is provided on the outside of the connecting rod; one end of the reset spring is fixedly connected to the connecting rod; the connecting rod slides inside the limiting groove.

[0012] A striking block is fixed to one end of the outer side of the spiral guide roller; the striking block is located outside the separation pipe.

[0013] An inclined plate is provided at the bottom of the inner side of the storage box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By using the spiral guide assembly and the filter assembly, the iron chips generated during the machine tool cutting process are centrally processed and then discharged. The cutting fluid and iron chips are first filtered and separated by a special-shaped filter screen. The inclined separation pipe, combined with the use of filter holes and liquid guide tanks, allows for secondary filtration and separation during the chip discharge process. Finally, the cutting fluid is recycled, resulting in a third filtration. Through the three separations of cutting fluid and iron chips, the occurrence of pollution caused by residual powdery iron chips in the cutting fluid is reduced. Furthermore, the blockage of the cutting fluid delivery pipe by fine iron chips is reduced, further increasing the practicality of the device.

[0015] By coating the surface of the striking block with a hard rubber layer, the vibration generated when it is repeatedly struck inside the storage tank reduces noise and minimizes damage to the inner wall of the device from frequent impacts. The vibration generated by the continuous striking increases the filtration effect of the cutting fluid. At the same time, the use of the inclined plate, combined with the vibration generated by the striking block, may cause powdery iron filings falling into the storage tank to flow into the high-density filter cartridge, reducing the possibility of fine iron filings accumulating inside the storage tank and increasing the cleanliness of the storage tank.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] like Figures 1-7 As shown, a centralized chip removal and filtration device with a spiral flow guiding structure includes a storage tank 1; a separation pipe 101 is fixedly connected to one side of the outer side of the storage tank 1; a special-shaped filter screen 102 is fixedly connected to the top of the inner side of the storage tank 1; the special-shaped filter screen 102 is interconnected with the separation pipe 101; and a spiral flow guiding assembly is located inside the separation pipe 101.

[0031] A filter assembly is located at the bottom inside the storage tank 1. The filter assembly includes a quick-release filter element mechanism and a rotating mechanism. A servo motor 2 is located inside the spiral guide assembly. The servo motor 2 is located on the outside of the separation pipe 101. A spiral guide roller 201 is fixedly connected to the output end of the servo motor 2. The spiral guide roller 201 rotates inside the separation pipe 101. Filter holes 202 are formed on the inner side of the separation pipe 101. A liquid guiding groove 203 is formed on the inner wall of the separation pipe 101. The filter assembly includes an isolation block 3. A drain outlet 301 is formed on the outside of the storage tank 1 near the isolation block 3. A fixed water outlet cylinder 302 is fixedly connected to the inside of the storage tank 1 near the isolation block 3. A rotating water outlet cylinder 303 is rotatably connected inside the fixed water outlet cylinder 302. The rotating water outlet cylinder 303 is... A return spring 305 is fixedly connected to the side; a blocking plate 306 is fixedly connected to one end of the return spring 305; the blocking plate 306 is slidably connected inside the rotating water outlet cylinder 303; a guide angle 307 is provided on the outer side of the blocking plate 306; a high-density filter cartridge 304 is slidably connected inside the rotating water outlet cylinder 303; the following mechanism includes a sliding groove 4; the sliding groove 4 is located inside the rotating water outlet cylinder 303; multiple sets of limiting blocks 401 are fixedly connected to the outer side of the high-density filter cartridge 304; the limiting blocks 401 slide inside the sliding groove 4; the filter element quick-release mechanism includes a limiting groove 5; the limiting groove 5 is located on one side outside the storage box 1; a release port 502 is provided on the outer side of the connecting rod 501; a connecting rod 501 is fixedly connected to one end of the return spring 305; the connecting rod 501 slides inside the limiting groove 5.

[0032] During operation, the storage tank 1 is connected to the chip discharge port on the machine tool. When the iron filings and cutting fluid generated during the operation of the machine tool enter the storage tank 1, they first fall into the shaped filter screen 102. Because the shaped filter screen 102 is funnel-shaped and has drainage holes inside, when the iron filings fall into the shaped filter screen 102, the larger iron filings will enter the shaped filter screen 102 through the bottom of the shaped filter screen 102. The cutting fluid that mixes with the iron filings during the cutting process will enter the storage tank 1 through the drainage holes inside the shaped filter screen 102.

[0033] At this time, the drive servo motor 2 drives the spiral guide roller 201 inside the separation pipe 101 to rotate, which spirally transports the iron filings falling into the separation pipe 101 and discharges them to the outside of the separation pipe 101. At the same time, the separation pipe 101 is tilted upward at an angle of 15 degrees, so that during the process of transporting the iron filings by the spiral guide roller 201, some of the cutting fluid that has entered the separation pipe 101 will flow along the separation pipe 101 into the storage tank 1. Meanwhile, the filter holes 202 opened on the inner side of the separation pipe 101... With the liquid guide tank 203, the spiral guide roller 201 stably discharges iron chips while continuously agitating them, allowing the residual cutting fluid inside the iron chips to be further separated and recycled. By designing the separation pipe 101 in an inclined manner, and in conjunction with the use of the liquid guide tank 203 and filter holes 202, the iron chips are filtered again during the chip discharge process, further reducing the waste of cutting fluid carried to the external environment with the iron chips, saving resources and reducing the pollution of the external environment by cutting fluid.

[0034] When the cutting fluid enters the storage tank 1, some powdery iron filings carried inside will also enter the storage tank 1. When the drain port 301 is connected to the cutting fluid spraying device of the machine tool, the cutting fluid will first enter the fixed water outlet 302 before flowing out of the drain port 301. Then, through the through-slot opened on the outer wall, it will gradually enter the rotating water outlet 303 and the high-density filter cartridge 304. Due to the characteristics of the storage tank 1 itself, the high-density filter cartridge 304 will filter out the powdery iron filings remaining in the cutting fluid. Then, the filtered cutting fluid will flow into the isolation block 3 through the rotating water outlet 303 and the fixed water outlet 302, and finally flow into the machine tool through the drain port 301. By filtering the powdery iron filings inside the cutting fluid, the blockage of the pipes by the powdery iron filings during the recycling of the cutting fluid is reduced.

[0035] When the filtration effect inside the return spring 305 is poor after prolonged use, press and rotate the water outlet cylinder 303 to start it rotating. At this time, the sliding groove 4 inside the rotating water outlet cylinder 303 cooperates with the limiting block 401 on the outside of the high-density filter cylinder 304, causing the high-density filter cylinder 304 to rotate as well. Then, the connecting rod 501 slides inside the limiting groove 5. When the connecting rod 501 is aligned with the release port 502, the connecting rod 501 can be pulled to pull out the high-density filter cylinder 304. At the same time, during the rotation of the rotating water outlet cylinder 303, the blockages pressed inside the rotating water outlet cylinder 303 are removed. When plate 306 rotates and approaches the groove on the side of fixed water outlet cylinder 302, it will be popped out by return spring 305. At this time, the guide angle 307 on the outer side of the blocking plate 306 will block the fixed water outlet cylinder 302. The shape of the guide angle 307 can provide a certain degree of sealing while guiding the force when rotating again, so that the blocking plate 306 can be pressed into the rotating water outlet cylinder 303 by the fixed water outlet cylinder 302 again. This facilitates the disassembly of the high-density filter cartridge 304 and reduces the occurrence of cutting fluid leakage during the disassembly process.

[0036] By using the spiral guide assembly and the filter assembly, the iron chips generated during the machine tool cutting process are centrally processed and then discharged. The cutting fluid and iron chips are first filtered and separated by the special-shaped filter screen 102. The inclined separation pipe 101, in conjunction with the use of filter holes 202 and liquid guide tank 203, allows for secondary filtration and separation during the chip discharge process. Finally, the cutting fluid is recycled, resulting in a third filtration. Through the three separations of cutting fluid and iron chips, the occurrence of residual powdery iron chips in the cutting fluid and the resulting pollution are reduced. Furthermore, the blockage of the cutting fluid delivery pipe by fine iron chips is reduced, further increasing the practicality of the device.

[0037] Example 2

[0038] like Figure 3 , Figure 5 As shown, a striking block 6 is fixed to one end of the outer side of the spiral guide roller 201; the striking block 6 is located outside the separation pipe 101, and an inclined plate 7 is provided at the bottom of the inner side of the storage box 1.

[0039] During operation, as the spiral guide roller 201 continuously rotates to transport iron filings, it drives the striking block 6 to rotate continuously. The surface of the striking block 6 is coated with a hard rubber coating, which reduces noise generation while continuously striking the inside of the storage bin 1, thus reducing damage to the inner wall of the device from frequent impacts. The vibration generated by the continuous striking increases the filtration effect of the cutting fluid. At the same time, the use of the inclined plate 7, combined with the vibration generated by the striking block 6, may cause the powdery iron filings falling into the storage bin 1 to flow into the high-density filter cartridge 304, reducing the possibility of fine iron filings accumulating inside the storage bin 1 and increasing the cleanliness inside the storage bin 1.
