Description

Technical Field

[0001] This invention relates to the field of cutting fluid circulation technology, specifically to a diversion-type cutting fluid filtration system and circulation method for a turning and grinding integrated machine tool. Background Technology

[0002] A turning and grinding integrated machine tool typically clamps the workpiece once and then performs turning and grinding operations on it. This avoids the errors caused by double clamping during the transition between turning and grinding operations, thus improving accuracy and saving labor costs.

[0003] CN116571008B discloses a cutting fluid circulation filtration system. The background technology addresses the following problem: An oil suction plate uses its special material and structure to adsorb floating oil onto its surface. When a scraper removes the floating oil from the surface of the oil suction plate, friction occurs between the scraper and the surface, damaging the oil suction plate and reducing its adsorption capacity for floating oil, resulting in low oil removal efficiency. This system utilizes a pushing component to move the scraper, which scrapes the floating oil to the oil outlet groove. The floating oil is then discharged through an oil guide plate, thus achieving separation of the floating oil from the cutting fluid. This results in high scraping efficiency and a long service life for the scraper.

[0004] Based on existing technologies, the following problems exist:

[0005] Existing cutting fluid circulation devices typically use a scraper to remove floating oil, achieving separation. However, during scraping, the oil easily adheres to the scraper's surface and flows to the bottom, reducing the scraping effect. Furthermore, the floating oil remains suspended on the cutting fluid surface and contacts the inner wall of the storage tank, hindering thorough removal. Existing devices can only scrape floating oil at a designated height. Once the cutting fluid enters the tank and reaches a certain height, the floating oil floats on the surface. The inability to adjust the scraping height further reduces oil removal efficiency. To address these issues, a diversion-type cutting fluid filtration system and circulation method for an integrated machine tool are proposed. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a split-flow cutting fluid filtration system and recycling method for a turning and grinding integrated machine tool. The system uses gas to scrape the floating oil on the surface of the cutting fluid without contacting the floating oil, thus improving the scraping effect. It also facilitates the scraping of the contact area between the floating oil and the cutting fluid storage tank, ensuring thorough scraping and improving the oil removal efficiency, which is convenient for subsequent recycling.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a diversion-type cutting fluid filtration system for a turning and grinding integrated machine tool, comprising an oil removal tank, a filter tank, and a collection hopper, further comprising a movable component disposed outside the oil removal tank, a U-shaped frame disposed on top of the movable component, and a lifting component disposed on top of the U-shaped frame, wherein an oil removal mechanism is disposed at the bottom of the lifting component, and a drain component is disposed on one side of the outer side of the oil removal tank, the oil removal mechanism comprising:

[0008] A mounting plate is located at the bottom of the lifting assembly. Fixing members are fixed to both sides of the bottom of the mounting plate. Mounting rods are fixed to the side walls of the fixing members. Horizontally arranged oil-removing components are provided on the side walls of the mounting rods for scraping oil stains from the liquid surface using gas. Auxiliary components for scraping residual oil stains on the inner wall of the oil removal tank are provided at both ends of the mounting rods. The oil-removing components include:

[0009] The spring is horizontally arranged and fixed on the side wall of the mounting rod. A mounting sleeve is fixed on the side of the spring away from the mounting rod, and the inner wall of the mounting sleeve is fitted onto the side wall of the mounting rod. A nozzle is fixed on the bottom of the outer wall of the mounting sleeve.

[0010] Furthermore, the degreasing assembly also includes:

[0011] The rotating plate has a fixed top of the outer wall with a mounting sleeve, and a stop rod is fixed on the side wall of the rotating plate. The stop rod contacts and presses against the inner wall of the oil removal tank, thereby driving the rotating plate, the mounting sleeve and the nozzle to rotate, so as to adjust the angle of the nozzle.

[0012] Furthermore, the auxiliary component includes:

[0013] Limit blocks are fixedly installed at both ends of the mounting rod;

[0014] The limiting seat is fitted onto the side wall of the limiting block and the mounting rod. A scraper for cleaning oil stains is fixedly provided at the bottom of the outer wall of the limiting seat. The lower and upper outer ends of the scraper are respectively provided with an inclined surface and a vertical surface. The scraper enters the oil removal tank through the inclined surface so that the vertical surface contacts the inner wall of the oil removal tank.

[0015] Furthermore, the auxiliary component also includes:

[0016] A limiting groove is formed on the inner wall of the limiting seat and is used to fit on the side wall of the mounting rod and the limiting block. The diameter of the side wall of the limiting block is larger than the diameter of the side wall of the mounting rod. The limiting block is used to limit the mounting rod. A spring is fitted on the side wall of the mounting rod inside the limiting groove, and the spring is located on the side of the limiting block closer to the mounting rod.

[0017] Furthermore, the sewage discharge assembly includes:

[0018] A sealing plate is fitted onto the inner wall of the oil removal tank. A drain channel is provided on one side of the outer side of the oil removal tank. The side wall of the sealing plate fits against the inner wall of the oil removal tank to block the drain channel. An inclined guide plate is fixed on the outer side of the sealing plate, and the top of the guide plate is concave. The side wall of the guide plate is fitted onto the inner wall of the drain channel.

[0019] The first electric push rod is fixedly installed on the outer side of the oil tank. The telescopic shaft of the first electric push rod is fixedly equipped with a connecting plate. The side wall of the connecting plate is fixedly connected to the inner side of the sealing plate and the guide plate, so as to drive the sealing plate and the guide plate to move vertically.

[0020] Furthermore, the moving component includes:

[0021] L-shaped plates are fixedly installed on both sides of the outer side of the oil tank. The top of each L-shaped plate is provided with a groove, and a slider is placed inside the groove. The top of the slider is fixedly connected to the bottom of the U-shaped frame.

[0022] The threaded rod is rotatably mounted on the side wall of the L-shaped plate and extends into the slide groove. The side wall of the threaded rod located in the slide groove is threadedly connected to the slider, and the two threaded rods are connected in a transmission to drive the oil removal mechanism to move.

[0023] The servo motor is fixedly mounted on the outside of the oil tank, and the output shaft of the servo motor is fixedly connected to one of the threaded rods through a coupling.

[0024] Furthermore, the lifting assembly includes:

[0025] The second electric push rod is fixedly installed on the top of the U-shaped frame, and the telescopic shaft of the second electric push rod extends to the inside of the U-shaped frame. The telescopic shaft of the second electric push rod is fixedly connected to the top of the mounting plate to drive the oil removal mechanism to rise and fall.

[0026] The guide rod is fixed on both sides of the top of the mounting plate, and the top of the guide rod extends to the top of the U-shaped frame. Linear bearings are fixed on both sides of the top of the U-shaped frame, and the side wall of the guide rod is sleeved on the inner wall of the inner ring of the linear bearing, so that when the guide rod moves vertically with the mounting plate, it drives the guide rod to move along the inner wall of the inner ring of the linear bearing, thereby limiting the movement of the mounting plate.

[0027] Furthermore, a multi-port pipe is fixedly provided at the drain end of the liquid collecting hopper, and a first conduit is fixedly provided at the drain end of the multi-port pipe. The drain end of the first conduit extends into the filter box and is located at the upper end of the filter box. The filter box is detachably equipped with a first filter structure and a second filter structure. A second conduit extending into the oil removal tank is fixedly provided at the drain end of the filter box, and the drain end of the second conduit is located at the lower end of the oil removal tank. The inlet end of the second conduit is located at the bottom of the first filter structure and the second filter structure. A water pump is provided on the side wall of the second conduit. Valves are provided on the outer walls of both the second conduit and the multi-port pipe.

[0028] A drain pipe is fixedly installed on the outside of the oil removal tank.

[0029] A method for recycling the diversion-type cutting fluid filtration system of a turning-grinding integrated machine tool, using the aforementioned diversion-type cutting fluid filtration system, includes the following steps:

[0030] S1: The opening or closing of the multi-port pipe is controlled by the valve, so that the cutting fluid used for machining and grinding enters the filter box through the collection hopper after use, and is filtered through the first filter structure and the second filter structure.

[0031] S2: The filtered cutting fluid enters the degreasing tank and is degreased by the degreasing mechanism. The oil on the surface of the cutting fluid is discharged from the degreasing tank through the drain assembly. The degreased cutting fluid is then recycled through the drain pipe.

[0032] Furthermore, the first and second filter structures are used to filter the cutting fluid used in grinding and turning processes, respectively.

[0033] This invention provides a diversion-type cutting fluid filtration system and a recycling method for an integrated turning and grinding machine tool.

[0034] Compared with existing technologies, it has the following advantages:

[0035] 1. This invention utilizes an oil removal component in its oil removal mechanism to blow away oil stains adhering to the surface of the cutting fluid using gas blowing, replacing the traditional method of scraping oil stains with a scraper. This avoids the oil stains adhering to the surface of the scraper during the traditional scraping process, thereby improving the oil removal effect. It also facilitates the scraping of oil stains at the contact points between the cutting fluid surface and the inner wall of the oil removal tank, further enhancing the cleaning and oil removal effect. The lifting component and the drain component work together to allow the oil stains on the surface of the cutting fluid to be blown and scraped at different heights, improving the oil removal efficiency. This also facilitates the filtration of the cutting fluid used for machining and grinding after diversion, thus enabling its recycling.

[0036] 2. This invention uses an oil removal component to scrape oil stains on the surface of the cutting fluid by spraying gas through a nozzle. This avoids direct contact with the oil stains, preventing the oil from adhering to the surface of the traditional scraper. First, the push rod contacts and presses against the inner wall of the oil removal tank, causing the push rod to drive the rotating plate and mounting sleeve to compress the spring, thus directing the nozzle towards the inner wall of the oil removal tank for more thorough oil removal. Then, a moving component moves the nozzle closer to the drain component. At this point, the push rod disengages from the inner wall of the oil removal tank, and under the reverse action of the spring, the nozzle returns to its original position, facing the drain component, so that the oil stains on the surface of the cutting fluid are blown out through the drain component.

[0037] 3. This invention uses a scraper from an auxiliary component to clean the oil stains at the contact point between the cutting fluid surface and the oil removal tank. Under the action of a spring, the scraper remains in close contact with the inner wall of the oil removal tank, ensuring a good cleaning effect. This also avoids the problem of installing a nozzle at the end of the mounting rod, which could cause gas to come into contact with the inner wall of the oil removal tank and flow back, affecting the cleaning effect on the middle section of the oil removal tank. As the scraper descends, its inclined surface first contacts the inner wall of the oil removal tank, thus preventing the scraper from failing to enter the oil removal tank under the action of the spring. As the lifting component drives the oil removal mechanism to descend continuously, the vertical surface of the cover plate is located at the contact point between the cutting fluid and the oil removal tank for cleaning.

[0038] 4. This invention, through the cooperation of a lifting mechanism and a drain assembly, facilitates the adjustment of the height of the nozzle and the sealing plate, ensuring that the height of the sealing plate matches the height of the cutting fluid in the degreasing tank. This facilitates the discharge of oil while simultaneously removing oil from the cutting fluid at different heights. Furthermore, since the second conduit is located at the lower end of the degreasing tank, oil continuously floats on the surface of the cutting fluid as it is continuously drained into the tank. During the draining process, and after the cutting fluid has reached a certain height, the height of the nozzle can be adjusted via the lifting assembly to remove oil, thereby improving efficiency.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The split-flow cutting fluid filtration system of the turning and grinding integrated machine tool includes an oil removal tank 1, a filter box 9 and a liquid collection hopper 7, as well as a moving component 2 set outside the oil removal tank 1, a U-shaped frame 14 set on the top of the moving component 2 and a lifting component 3 set on the top of the U-shaped frame 14. An oil removal mechanism 4 is set at the bottom of the lifting component 3, and a sewage discharge component 10 is set on one side of the outer side of the oil removal tank 1.

[0060] A multi-port pipe 8 is fixedly provided at the drain end of the liquid collecting hopper 7. A first conduit 6 is fixedly provided at the drain end of the multi-port pipe 8. The drain end of the first conduit 6 extends into the filter box 9 and is located at the upper end of the filter box 9. A first filter structure 12 and a second filter structure 13 are detachably installed inside the filter box 9. A second conduit 5 is fixedly provided at the drain end of the filter box 9 and extends into the oil removal tank 1. The drain end of the second conduit 5 is located at the lower end of the oil removal tank 1. The inlet end of the second conduit 5 is located at the bottom of the first filter structure 12 and the second filter structure 13. A water pump is provided on the side wall of the second conduit 5. Valves are provided on the outer walls of both the second conduit 5 and the multi-port pipe 8.

[0061] A drain pipe 11 is fixedly installed on the outside of the oil tank 1.

[0062] In specific implementation, the liquid collection hopper 7 is installed inside the integrated turning and grinding machine and is located at the bottom of the turning and grinding processing position, so as to collect and guide the liquid after use. The shape of the liquid collection hopper 7 is determined according to the integrated turning and grinding machine and is not limited here. The above is the prior art and will not be elaborated here.

[0063] Please see Figure 5 , Figure 6 and Figure 7 The oil removal mechanism 4 includes:

[0064] Mounting plate 42 is set at the bottom of lifting assembly 3. Fixing members 45 are fixed on both sides of the bottom of mounting plate 42. Mounting rod 43 is fixed on the side wall of fixing member 45. Oil removal assembly 44 is horizontally arranged on the side wall of mounting rod 43 for scraping oil stains on the liquid surface by gas. Auxiliary assembly 41 is set at both ends of mounting rod 43 for scraping oil stains remaining on the inner wall of oil removal tank 1.

[0065] Please see Figure 8 The degreasing component 44 includes:

[0066] The spring 444 is horizontally arranged and fixed on the side wall of the mounting rod 43. The side of the spring 444 away from the mounting rod 43 is fixedly provided with the mounting sleeve 443, and the inner wall of the mounting sleeve 443 is fitted onto the side wall of the mounting rod 43. The bottom of the outer wall of the mounting sleeve 443 is fixedly provided with the nozzle 445.

[0067] The degreasing assembly 44 also includes:

[0068] The rotating plate 442 has a fixed top of the outer wall of the mounting sleeve 443. The side wall of the rotating plate 442 is fixed with a push rod 441. The push rod 441 contacts and presses against the inner wall of the oil removal tank 1, thereby driving the rotating plate 442, the mounting sleeve 443 and the nozzle 445 to rotate, so as to adjust the angle of the nozzle 445.

[0069] In practice, the lifting assembly 3 lowers the oil removal assembly 44 to a specified height from the cutting fluid. Then, the moving assembly 2 moves it away from the drain assembly 10, so that the push rod 441 contacts and presses against the inner wall of the oil removal tank 1. This causes the push rod 441 to drive the rotating plate 442 and the mounting sleeve 443 to compress the spring 444, thereby adjusting the angle of the nozzle 445 so that the nozzle 445 faces the inner wall of the oil removal tank 1, making it easier to scrape the oil stains more thoroughly. Then, the moving assembly 2 moves the nozzle 445 closer to the drain assembly 10. At this time, the push rod 441 disengages from the inner wall of the oil removal tank 1. Under the reverse action of the spring 444, the nozzle 445 resets and faces the drain assembly 10, so that the oil stains on the surface of the cutting fluid can be blown out by the drain assembly 10.

[0070] The nozzle 445 is connected to an external blower and compressor via a conduit so that gas can be ejected through the nozzle 445. The conduit needs to be reserved with the length to move with the moving component 2 for practical use.

[0071] Nozzle 445 can be strip-shaped or fan-shaped, which is convenient for actual blowing use. The spacing between nozzles 445 should not leave any dead corners to ensure sufficient blowing and scraping.

[0072] Please see Figure 9 Auxiliary component 41 includes:

[0073] Limiting blocks 413 are fixedly installed at both ends of the mounting rod 43;

[0074] The limiting seat 412 is sleeved on the side wall of the limiting block 413 and the mounting rod 43. The bottom of the outer wall of the limiting seat 412 is fixedly provided with a scraper 411 for cleaning oil stains. The lower outer end and the upper outer end of the scraper 411 are respectively provided with an inclined surface 416 and a vertical surface 415. The scraper 411 enters the oil removal tank 1 through the inclined surface 416 so that the vertical surface 415 contacts the inner wall of the oil removal tank 1.

[0075] Auxiliary component 41 also includes:

[0076] A limiting groove 414 is formed on the inner wall of the limiting seat 412 and is used to fit on the side wall of the mounting rod 43 and the limiting block 413. The side wall diameter of the limiting block 413 is larger than the side wall diameter of the mounting rod 43. The limiting block 413 is used to limit the mounting rod 43. A spring is fitted on the side wall of the mounting rod 43 within the limiting groove 414 and is located on the side of the limiting block 413 closer to the mounting rod 43.

[0077] In specific implementation, when the lifting assembly 3 drives the oil removal mechanism 4 to move downward, the inclined surface 416 of the scraper 411 first contacts the inner wall of the oil removal tank 1, thereby preventing the scraper 411 from failing to enter the oil removal tank 1 under the action of the spring. As the lifting assembly 3 drives the oil removal mechanism 4 to continuously descend, the vertical surface 415 of the cover plate is located at the contact position between the cutting fluid and the oil removal tank 1. Subsequently, as the moving assembly 2 moves, the scraper 411 cleans the oil stains at the contact position between the cutting fluid surface and the oil removal tank 1. Under the action of the spring, the scraper 411 is always in close contact with the inner wall of the oil removal tank 1, ensuring the cleaning effect and avoiding the installation of the nozzle 445 at the end of the mounting rod 43, which would cause the gas to come into contact with the inner wall of the oil removal tank 1 and flow back, affecting the blowing and cleaning effect on the middle section of the oil removal tank 1.

[0078] Please see Figure 10 The mobile component 2 includes:

[0079] L-shaped plates 24 are fixedly installed on both sides of the outer side of the oil tank 1. The top of each L-shaped plate 24 is provided with a groove 23, and a slider is placed inside each groove 23. The top of the slider is fixedly connected to the bottom of the U-shaped frame 14.

[0080] The threaded rod 22 is rotatably mounted on the side wall of the L-shaped plate 24 and extends into the slide groove 23. The side wall of the threaded rod 22 located in the slide groove 23 is threadedly connected to the slider, and the two threaded rods 22 are connected in a transmission manner to drive the oil removal mechanism 4 to move.

[0081] The servo motor 21 is fixedly installed on the outside of the oil tank 1, and the output shaft of the servo motor 21 is fixedly connected to one of the threaded rods 22 through a coupling.

[0082] In practical implementation, the servo motor 21 is started. The output shaft of the servo motor 21 drives one of the threaded rods 22 to rotate through the coupling. Since the two threaded rods 22 are connected by transmission, the two threaded rods 22 rotate synchronously. During the rotation of the threaded rods 22, the slider moves along the slide groove 23, thereby driving the U-shaped frame 14 and the oil removal mechanism 4 to move, so as to discharge the blown oil stains to the outside of the oil removal tank 1 through the sewage discharge component 10.

[0083] The transmission mechanism for the two threaded rods 22 can be a gear and chain transmission method, which is existing technology and will not be described in detail here.

[0084] Example 2, please refer to Figure 11 and Figure 12 The technical difference between this embodiment and embodiment one is that the sewage discharge component 10 includes:

[0085] A sealing plate 101 is fitted onto the inner wall of the oil removal tank 1. A drain channel is provided on one side of the outer side of the oil removal tank 1. The side wall of the sealing plate 101 is fitted against the inner wall of the oil removal tank 1 to block the drain channel. An inclined guide plate 102 is fixed on the outer side of the sealing plate 101. The top of the guide plate 102 is concave. The side wall of the guide plate 102 is fitted onto the inner wall of the drain channel.

[0086] The first electric push rod 103 is fixedly installed on the outer side of the oil tank 1. The telescopic shaft of the first electric push rod 103 is fixedly provided with a connecting plate 104. The side wall of the connecting plate 104 is fixedly connected to the inner side of the sealing plate 101 and the guide plate 102, so as to drive the sealing plate 101 and the guide plate 102 to move vertically.

[0087] In practice, the moving component 2 drives the degreasing component 44 to blow the oil on the surface of the cutting fluid toward the drain channel of the drain component 10, so that the oil is discharged to the outside of the degreasing tank 1 through the drain channel, and then flows to the designated position through the concave part of the guide plate 102 for degreasing.

[0088] By setting the first electric push rod 103, the height of the sealing plate 101 can be easily adjusted so that the height of the sealing plate 101 is consistent with the height of the cutting fluid in the degreasing tank 1. This facilitates the discharge of oil stains and the removal of oil from the cutting fluid in the degreasing tank 1 at different heights. Since the second conduit 5 is located at the lower end of the degreasing tank 1, the oil stains will continuously float on the surface of the cutting fluid as it is continuously discharged into the degreasing tank 1. This allows for oil removal during the discharge of the cutting fluid and after the cutting fluid has been discharged to a certain height, thus improving the performance.

[0089] Please see Figure 6 The lifting assembly 3 includes:

[0090] The second electric push rod 31 is fixedly mounted on the top of the U-shaped frame 14, and the telescopic shaft of the second electric push rod 31 extends to the inner side of the U-shaped frame 14. The telescopic shaft of the second electric push rod 31 is fixedly connected to the top of the mounting plate 42 to drive the oil removal mechanism 4 to rise and fall.

[0091] The guide rod 32 is fixedly mounted on both sides of the top of the mounting plate 42, and the top of the guide rod 32 extends to the top of the U-shaped frame 14. The top two sides of the U-shaped frame 14 are fixedly mounted with linear bearings 33, and the side wall of the guide rod 32 is sleeved on the inner wall of the inner ring of the linear bearing 33, so that when the guide rod 32 moves vertically with the mounting plate 42, it drives the guide rod 32 to move along the inner wall of the inner ring of the linear bearing 33, thereby limiting the movement of the mounting plate 42.

[0092] In practical implementation, the oil storage mechanism is raised and lowered by the telescopic shaft of the second electric push rod 31, which makes it easy to adjust the height of the oil storage mechanism and make it easy to place the nozzle 445 at a specified height to blow away the oil on the surface of the cutting fluid. It is also suitable for cutting fluids of different heights.

[0093] By setting guide rod 32 and linear bearing 33, the vertically moving mounting plate 42 is limited, thereby limiting the nozzle 445 and other components, and improving the stability of lifting.

[0094] The servo motor 21 and the first electric push rod 103 of the present invention are all connected to an external controller and power supply through wires for actual control and use. This is prior art and will not be described in detail here.

[0095] This invention also provides a method for recycling a split-flow cutting fluid filtration system for an integrated turning and grinding machine tool. The method, employing a split-flow cutting fluid filtration system for an integrated turning and grinding machine tool, includes the following steps:

[0096] S1: The opening or closing of the multi-port pipe 8 is controlled by the valve on the outer wall of the multi-port pipe 8, so that the cutting fluid used for machining and grinding can enter the filter box 9 through the collection hopper 7 and the first conduit 6 after use, and be filtered through the first filter structure 12 and the second filter structure 13.

[0097] S2: The filtered cutting fluid enters the degreasing tank 1 through the water pump and the second conduit 5. It is degreased by the degreasing mechanism 4, so that the oil on the surface of the cutting fluid is discharged from the degreasing tank 1 through the drain assembly 10. The degreased cutting fluid is discharged through the drain pipe 11, and the drain end of the drain pipe is connected to the cutting fluid storage tank for recycling.

[0098] When specifically cleaning oil stains from the cutting fluid, a blower and compressor are connected to the nozzle 445 to spray gas through the nozzle 445. This gas blowing method cleans the oil stains on the cutting fluid surface, avoiding the problem of oil stains adhering to the surface of the traditional scraper 411, which affects the cleaning effect. It also facilitates cleaning the contact area between the fluid surface and the inner wall of the oil removal tank 1, improving the oil removal effect. In practice, the moving component 2 positions the oil removal mechanism 4 on the side of the oil removal tank 1 away from the drain component 10. Then, the lifting component 3 lowers the oil removal mechanism 4 into the oil removal tank 1, to a specified height above the fluid surface. Since gas blowing is used for cleaning, it does not need to contact the liquid surface. During this process, the auxiliary component 41 is in contact with the inner wall of the oil removal tank 1, which can clean the oil stains at the contact position between the cutting fluid surface and the oil removal tank 1. Then, the moving component 2 continues to drive the oil removal mechanism 4 to move away from the drain component 10, so that the push rod 441 of the oil removal component 44 contacts and presses against the inner wall of the oil removal tank 1, causing the nozzle 445 to rotate, which facilitates the cleaning and oil removal at the contact position between the liquid surface and the inner wall of the oil removal tank 1. Then, the moving component 2 drives the oil removal mechanism 4 to move closer to the drain component 10, thereby discharging the oil stains from the cutting fluid surface.

[0099] The lifting assembly 3 and the drain assembly 10 allow the height of the oil scraping to be determined according to the height of the cutting fluid in the oil removal tank 1, thus improving applicability.

[0100] The first filter structure 12 and the second filter structure 13 are used to filter the cutting fluid used in grinding and turning respectively. Since the cutting fluids used in turning and grinding are different, for example, the chips produced in turning are larger in volume, while the chips produced in grinding are smaller in volume. Therefore, the filter structures used to filter the cutting fluid after the cutting fluid processing is completed are different, and different filter structures are required for filtration. The first filter structure 12 and the second filter structure 13 are existing technologies and will not be described in detail here.

[0101] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
