Description

Technical Field

[0001] The present invention relates to the technical field of industrial processing, and more specifically, to a liquid and chip separation device and method for a numerical control machining center of new energy core components. Background Art

[0002] Metal processing refers to the production activities of humans to process materials composed of metal elements or mainly composed of metal elements with metallic properties. Specifically, metal processing, abbreviated as metalworking, is a process technology that processes metal materials into articles, parts, and components, including large parts such as bridges and ships, and even delicate components such as engines, jewelry, and watches. It is widely used in different fields such as science, industry, and artworks.

[0003] When the existing lathes are in processing, coolant is required for cooling. However, the collected coolant contains iron chips. Traditionally, filter plates or filter meshes are used for filtration. However, when filtering through filter plates and filter meshes, very fine iron chips in the liquid cannot be filtered out, resulting in the influence on the machining accuracy and the service life of the machining tool during the recycling of the coolant, as well as causing failures of the coolant suction pump.

[0016] Preferably, the usage method of the liquid-chip separation device of the new energy core component numerical control machining center includes the following steps:

Detailed implementation manners

[0038] Hereinafter, the technical solutions of the present invention will be described in detail by way of examples with reference to the accompanying drawings. It should be noted here that the description of these example embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0039] As used herein, the term "and / or" merely describes the associated relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, B exists alone, and both A and B exist simultaneously. The term " / and" as used herein describes another associated object relationship, indicating that there can be two relationships. For example, A / and B can represent two situations: A exists alone, and both A and B exist. Additionally, the character " / " as used herein generally indicates that the associated objects before and after are in an "or" relationship.

[0040] According to Figures 1-8 As shown, a liquid and chip separation device and method for a new energy core component numerical control machining center include a cutting fluid self-filtering and collecting member and a cutting fluid fine-filtering and collecting member. The cutting fluid self-filtering and collecting member is disposed on the ground, and the cutting fluid fine-filtering and collecting member is connected to the cutting fluid self-filtering and collecting member. The cutting fluid self-filtering and collecting member includes an iron chip self-filtering member and an iron chip collecting member, and the iron chip collecting member is disposed on the iron chip self-filtering member. The iron chip self-filtering member includes an iron chip filtering box 1, an iron chip filter screen 2, and an iron chip collecting pipe 3. The iron chip filtering box 1 is in a rectangular box shape and is horizontally disposed on the ground, and the horizontal height of the iron chip filtering box 1 is less than the horizontal height of the machining table of the numerical control machining center. The iron chip filter screen 2 is disposed on one port of the iron chip filtering box 1 to prevent small-diameter iron chips from passing through the iron chip filter screen 2 and entering the cutting fluid fine-filtering and collecting member. The iron chip filter screen 2 is used to filter iron chips with a diameter equal to or larger than a small diameter in the cutting fluid. Limited by the mesh size of the iron chip filter screen 2, it is unable to filter tiny particle iron chips in the cutting fluid. The iron chip collecting pipe 3 is in a reduced-diameter tubular shape, and the small end of the iron chip collecting pipe 3 is vertically and penetratingly connected to the iron chip filtering box 1. The horizontal height of the large end of the iron chip collecting pipe 3 is less than the horizontal height of the machining table of the numerical control machining center, so that the cut iron chips can enter from the large end of the iron chip collecting pipe 3. The cutting fluid entering the iron chip collecting pipe 3 will flow along the iron chip collecting pipe 3 into the iron chip filtering box 1 and be blocked by the iron chip filter screen 2 and temporarily stored in the iron chip filtering box 1. As the cutting fluid flowing into the iron chip collecting pipe 3 increases, the cutting fluid will also accumulate in the iron chip collecting pipe 3. The iron chip collecting member is used to control the collection height of the cutting fluid in the iron chip collecting pipe 3, and the iron chips in the iron chip collecting pipe 3 and the iron chip filtering box 1 are used to filter the subsequent entering cutting fluid. The collection efficiency of the cutting fluid is improved, the collection cost of the cutting fluid is reduced, the wear of the iron chip filter screen 2 is reduced, and the economic benefit of cutting fluid collection is improved.

[0041] The iron filings collection member includes an iron filings baffle 4 and an iron filings extraction member. The size of the iron filings baffle 4 is not greater than the size of the inner wall of the iron filings filter box 1. One end of the iron filings baffle 4 is vertically installed in a guiding tube 5 on the side wall of the top surface of the iron filings filter box 1. The guiding tube 5 is in the shape of a rectangular tube, and the inner diameter length of the guiding tube 5 is the same as the inner diameter of the iron filings filter box 1. The guiding tube 5 is used for the iron filings baffle 4 to vertically slide into the iron filings filter box 1 along the guiding tube 5, and can prevent the iron filings in the iron filings filter box 1 from squeezing towards the iron filings filter net 2, so as to separate the iron filings in the iron filings filter box 1 from the iron filings filter net 2 and further reduce the wear of the iron filings filter net 2. Further, a first slider is provided on the iron filings baffle 4. After the iron filings baffle 4 completely enters the iron filings filter box 1 vertically, the first slider cooperates with a first sliding groove on the inner wall of the iron filings filter box 1. The longitudinal line of the first sliding groove is parallel to the longitudinal line of the iron filings filter box 1, so as to facilitate the iron filings baffle 4 to be adsorbed by the iron filings extraction member and slide towards the other end of the iron filings filter box 1. It should be noted that after the iron filings baffle 4 that is sucked towards the other end of the iron filings filter box 1 moves a certain distance, one iron filings baffle 4 will automatically slide into the iron filings filter box 1 from the guiding tube 5 under the action of gravity. A one-way through hole is provided on the iron filings baffle 4, and a one-way valve is provided on the one-way through hole. The one-way valve can allow the cutting fluid in the cutting fluid to pass through the one-way through hole unidirectionally. Specifically, the top end of the one-way valve is hinged to the top end of the one-way through hole, and the one-way valve closes one end of the one-way through hole by gravity. When the water pressure at the other end of the one-way through hole is greater than a predetermined value, the one-way valve will be pushed open and flow towards the iron filings filter net 2. Eighty-one one-way through holes are provided, and the eighty-one one-way through holes are distributed in a matrix on the iron filings baffle 4. It should be noted that when the iron filings baffle 4 is attracted by the iron filings collection member and slides to a predetermined distance towards the other end of the iron filings collection box, the two ends of the iron filings collection box will be sealed and separated to prevent the cutting fluid in the other end of the iron filings collection box from entering one end of the iron filings collection box through the iron filings baffle 4 from the other end of the iron filings collection box, so as to facilitate the staff to take out the iron filings from one end of the iron filings collection box. Further, a sealing ring 6 is fixedly provided at a predetermined position in the middle of the iron filings collection box. The sealing ring 6 can separate and seal the two ends of the iron filings collection box by cooperating with the four sides of the iron filings baffle 4, and the sealing ring 6 can also play a role in limiting the iron filings baffle 4 to prevent the iron filings baffle 4 from moving excessively.

[0042] The iron filings extraction member includes an extraction plate 7, a first magnet attachment 8, and a pulling extraction member. The extraction plate 7 is in the shape of a rectangular plate and is installed in the iron filings collection box, separating and sealing both ends of the iron filings collection box to prevent the cutting fluid entering from the iron filings collection pipe 3 from passing through the extraction plate 7 and entering the other end of the iron filings collection box. The four sides of the extraction plate 7 cooperate with the sealing ring 6 to separate and seal both ends of the iron filings collection box. The first magnet attachment 8 includes an iron core and a first magnetic coil. One end of the iron core is horizontally and fixedly arranged on one end face of the extraction plate 7, and the first magnetic coil is sleeved on the iron core to increase the magnetic adsorption force of the first magnet attachment 8. Further, there are sixteen first magnet attachments 8, and the sixteen first magnet attachments 8 are distributed in a matrix on the extraction plate 7 to increase the magnetic adsorption force of the first magnet attachments 8 on the iron filings inside one end of the magnet filtration box through the extraction plate 7. The pulling extraction member includes a transmission rod 9, a pulling pipe 10, and a second magnetic coil 11. One end of the transmission rod 9 is horizontally and perpendicularly fixedly arranged on one end face of the extraction plate 7. The pulling pipe 10 is fixedly arranged inside the other end pipe of the iron filings filtration box 1 through a pulling fixing frame 12, and the pulling pipe 10 is sleeved on the other end of the transmission rod 9. The second magnetic coil 11 is fixedly installed inside the pulling pipe 10 and is sleeved on the other end of the transmission rod 9. When a positive direct current is passed through the second magnetic coil 11, it will pull the other end of the transmission rod 9 towards the other end of the iron filings filtration box 1. The transmission rod 9 pulls the extraction plate 7 towards the other end of the iron filings filtration box 1. The extraction plate 7 pulls the iron filings inside one end of the iron filings filtration box 1 towards the other end of the iron filings filtration box 1 through the first magnet attachments 8. After the iron filings are pulled to a predetermined position inside the iron filings filtration box 1, they are taken out through the collection door 13 on the side wall of the other end of the iron filings filtration box 1. Then, a reverse direct current is passed through the second magnetic coil 11 to generate a magnetic field to push the extraction plate 7 towards one end of the iron filings filtration box 1 to a predetermined position to complete the reset of the extraction plate 7. It should be noted that the iron filings in the iron filings collection pipe 3 will automatically enter the iron filings filtration box 1 under the action of gravity, so as to facilitate the iron filings collection pipe 3 to continue collecting iron filings and improve the efficiency of iron filings self-filtration.

[0043] The cutting fluid fine filtration and collection component includes a relay pipe, a self-weight spiral adsorption component, an iron chip particle scraping component, and an iron chip particle collection component. The relay pipe is arranged on the iron chip filtration box 1. The automatic spiral adsorption component is connected to the relay pipe. Both the iron chip particle scraping component and the iron chip particle collection component are arranged on the self-weight spiral adsorption component. The relay pipe includes a reduced-diameter relay pipe 14 and a relay flow-through pipe 15. The reduced-diameter relay pipe 14 is a pipe with a round top and a square bottom. The large end of the reduced-diameter relay pipe 14 is connected through and to one port of the iron chip filtration box 1, and is used to divert the cutting fluid with tiny particle iron chips after being filtered by the iron chip filter screen 2 to the self-weight spiral adsorption component through the relay pipe. One end of the relay flow-through pipe 15 is connected through and to the small end of the reduced-diameter relay pipe 14. The self-weight spiral adsorption component includes a spiral adsorption barrel 16 and a spiral adsorption sheet 17. The diameter of the spiral adsorption barrel 16 is larger than the diameter of the relay flow-through pipe 15. Magnet steel sheets are fixedly attached to the inner wall of the spiral adsorption barrel 16 to increase the magnetic adsorption force on the inner wall of the spiral adsorption barrel 16. The spiral adsorption barrel 16 is vertically installed in a pit dug on the ground, and the top surface of the spiral adsorption barrel 16 is connected through and to the other end of the relay flow-through pipe 15. The height of the top of the spiral adsorption barrel 16 is less than the height of the iron chip filtration box 1, so that the cutting fluid can flow into the spiral adsorption barrel 16 by its own weight. The spiral adsorption sheet 17 is in a spiral sheet shape. The spiral adsorption sheet 17 has magnetism. The inner diameter of the spiral adsorption sheet 17 is the same as the inner diameter of the spiral adsorption barrel 16. The length of the spiral adsorption sheet 17 is less than the length of the spiral adsorption barrel 16. The spiral adsorption sheet 17 is fixedly embedded in the spiral adsorption barrel 16, so that a predetermined length is left between both ends of the spiral adsorption sheet 17 and the two end surfaces of the spiral adsorption barrel 16 respectively. The spiral adsorption sheet 17 and the inner wall of the spiral adsorption barrel 16 together form a spiral channel in the spiral adsorption barrel 16. The cutting fluid that enters the spiral adsorption barrel 16 through the relay flow-through pipe 15 flows from one end of the spiral adsorption barrel 16 into the spiral channel and then to the other end of the spiral adsorption barrel 16. The tiny particle iron chips that spiral-flow with the cutting fluid in the spiral channel are pushed and adsorbed on the spiral adsorption sheet 17 and the inner wall of the spiral adsorption barrel 16 under the action of gravity and centrifugal force. A cutting fluid reuse pipe 18 is connected through and to the bottom side wall of the spiral adsorption barrel 16. The free end of the cutting fluid reuse pipe 18 is connected to a pump, and is used to pump the cutting fluid filtered by the cutting fluid self-filtration collection component and the cutting fluid fine filtration and collection component to the machining center for reuse. Further, when the cutting fluid reuse pipe 18 discharges liquid, the power screw 20 is in a non-forward rotation state to prevent the tiny particle iron chips adsorbed on the inner wall of the spiral adsorption barrel 16 and the spiral adsorption sheet 17 from falling off and being sucked into the cutting fluid reuse pipe 18.

[0044] The iron filings particle scraping member includes a scraping power member and an iron filings scraping member. The scraping power member is arranged on the spiral adsorption barrel 16, and the iron filings scraping member is arranged on the scraping power member. The scraping power member includes a power fixing pipe 19, a power screw 20, a power nut 21, a power motor 22, a transmission shaft, a worm 24 and a worm gear 25. Both end faces of the power fixing pipe 19 are closed. The power fixing pipe 19 is fixedly embedded in the inner ring of the spiral adsorption sheet 17. A spiral groove 26 is arranged on the side wall of the power fixing pipe 19. There are two spiral grooves 26, and the two spiral grooves 26 are vertically spaced apart, and the vertical distance between the two spiral grooves 26 is less than the pitch of the spiral adsorption sheet 17, so that both of the two spiral grooves 26 are located in the spiral channel. The diameter of the power screw 20 is smaller than the inner diameter of the power fixing pipe 19. Both ends of the power screw 20 are respectively arranged on both end faces of the power fixing pipe 19, and the axis of the power screw 20 coincides with the axis of the power fixing pipe 19. At the same time, the power screw 20 can rotate circumferentially on the power fixing pipe 19. The power nut 21 is fitted and sleeved on the power screw 20. When the power screw 20 rotates, it will drive the power nut 21 to move up and down axially. The power motor 22 is fixedly arranged on the spiral adsorption barrel 16. One end of the transmission shaft penetrates through the spiral adsorption barrel 16 and is fixedly connected to the rotating shaft of the power motor 22. The worm 24 is fixedly arranged on the other end of the transmission shaft. The worm gear 25 is fixedly sleeved on the bottom end of the power screw 20, and the worm gear 25 meshes with the worm 24. Thus, the power motor 22 drives the power screw 20 to rotate in the power fixing pipe 19 through the transmission shaft, the worm 24 and the worm gear 25. It should be noted that since both end faces of the power fixing pipe 19 are closed, and the spiral grooves 26 distributed in a spiral shape are all in the spiral channel, and at the same time, the cutting fluid in a spiral flow state is affected by the centrifugal force, so that the water pressure at the position with a larger radius from the power fixing pipe 19 is higher, while the water pressure near the power fixing pipe 19 is lower, so that the cutting fluid in the spiral channel will not flow from one end of the spiral adsorption barrel 16 to the other end of the spiral adsorption barrel 16 through the diameter of the spiral groove 26 during the spiral downward flow process.

[0045] The iron filings scraping member includes a scraping drive rod 27, a scraping drive tube, a scraping plate, and a torsion spring.

After the iron filings collection box 36 is full, the staff can pull out the iron filings collection box 36 from the well dug from the ground to complete the collection of the tiny iron filings particles. Then, another iron filings collection box 36 is put into the well dug from the ground, and the iron filings adsorption port is aligned with the other end of the iron filings collection relay pipe 35.
