Description

Technical Field

[0001] The present invention relates to the technical field of cutting fluid filtration for machine tool processing, and specifically refers to a cutting fluid filtration device for machine tools. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces, and it can be recycled under the condition of sufficient filtration.

[0003] Existing cutting fluid filtration devices for machine tools generally include a transfer container and a filter disposed within the transfer container. After the filter effectively filters out the chips in the cutting fluid, the cutting fluid is recycled. Since oil stains existing in machining are often mixed in during the recycling process of the cutting fluid, affecting the normal use of the cutting fluid, an overflow mechanism is generally additionally provided in the existing transfer container to overflow and discharge the oil stains floating on the surface of the cutting fluid, thereby achieving the removal of oil stains. Such a cutting fluid filtration device for machine tools has the following defects in actual use: 1) The controllability of oil stain removal is insufficient, and there are often situations where the oil stains are not removed completely or the cutting fluid is discharged as oil stains; 2) When the filter is blocked by chips, it is necessary to stop the machine and then manually reach into the cutting fluid to clean and discharge the filter in a timely manner. Not only is the cleaning and discharging difficult, but the chips during the cleaning and discharging process are likely to fall into the transfer container, which is very troublesome.

[0004] Therefore, the research objective of the present invention is to design a cutting fluid filtration device for machine tools that can effectively and significantly improve the controllability of oil stain removal, thereby efficiently removing the oil stains floating on the surface of the cutting fluid; and can conveniently and efficiently clean and discharge the chips blocked on the filter. Summary of the Invention

[0005] In view of the above technical problems existing in the prior art, the present invention provides a cutting fluid filtration device for machine tools, which can effectively solve the above technical problems existing in the prior art.

[0006] The technical solution of the present invention is as follows: A cutting fluid filtration device for machine tools includes a cutting fluid diversion channel for diverting the cutting fluid generated by machine tool processing, and a filter disposed on the cutting fluid diversion channel for filtering chips in the flowing cutting fluid; the cutting fluid filtration device further includes an oil stain removal assembly, and the oil stain removal assembly includes: The oil removal motor is fixedly installed on the upper part of one side of the discharge end of the cutting fluid diversion channel. The output shaft end of the oil removal motor is drivingly connected with a group of transmission discs whose bottom sides penetrate and extend into the cutting fluid diversion channel. The group of transmission discs is made of elastic plates, and an oil absorption material layer is fixedly connected to the outer side surfaces of the group of transmission discs in a V shape; The lifting float body can be lifted and lowered under the guidance of a corresponding limiting mechanism on the lower side of the bottom end of the transmission disc. A transmission wheel corresponding to the bottom end of the transmission disc is rotatably installed on the lifting float body. The lifting float body floats on the top of the cutting fluid to drive the transmission wheel to fixedly abut against the bottom ends of the group of transmission discs and form an upward driving force on the bottom ends of the transmission discs. The bottom ends of the group of transmission discs are bent outwards under the drive of the transmission wheel and are located on the top of the cutting fluid.

[0007] A cover for isolating the group of transmission discs is arranged on one side of the oil removal motor. A scraping plate for scraping the oil adsorbed by the oil absorption material layer is arranged on the cover, and a material guiding groove for discharging the scraped oil into a corresponding oil storage box body is also arranged on the cover.

[0008] The limiting mechanism adopts a group of fixed columns, and a fixed hanging ring sleeved on the fixed columns is fixedly connected to the lifting float body.

[0009] A plurality of longitudinal filtering chambers are arranged in the cutting fluid diversion channel. The longitudinal filtering chambers are divided into a circulation area and a filtering area from front to back. The filter comprises a filter plate detachably inserted between the circulation area and the filtering area. A plurality of filtering holes are arranged in the middle of the filter plate; the circulation area of the longitudinal filtering chamber on one side of the feed end of the cutting fluid diversion channel is connected to the discharge end of a corresponding cutting fluid collection tank. Between two adjacent longitudinal filtering chambers, the filtering area of the previous longitudinal filtering chamber is connected to the circulation area of the next longitudinal filtering chamber. The filtering area of the longitudinal filtering chamber on one side of the discharge end of the cutting fluid diversion channel is connected to the feed end of a corresponding oil outlet chamber. The oil outlet chamber is pumped to the feed end of the machine tool cutting fluid feeding mechanism, and the oil removal assembly is fixedly installed on the upper part of the oil outlet chamber.

[0010] Corresponding baffles are respectively turned forward on both sides and the bottom of the filter plate. The front end parts of the baffles are fixedly connected with corresponding U-shaped clamping plates in a T shape. Corresponding cover plates are fixedly connected to the tops of the filter plate, the baffles and the U-shaped clamping plates; corresponding slots are respectively arranged obliquely between the circulation area and the filtering area of the longitudinal filtering chamber. The filter plate is inserted between the circulation area and the filtering area of the longitudinal filtering chamber through the cooperation of both sides of the U-shaped clamping plate and the corresponding slots, and the bottom of the U-shaped clamping plate is closed and abutted against the bottom surface of the longitudinal filtering chamber.

[0011] On both sides of the U-shaped clamping plate, corresponding guide seats are movably installed between the U-shaped clamping plate and the corresponding filter plates. A corresponding connecting plate is fixedly connected between the tops of the guide seats. Between the middles of the guide seats, a magnet bar arranged in an axial shape is rotatably installed. On the upper side of the connecting plate, a corresponding airbag is fixedly connected. The airbag is connected to an external air compressor through a corresponding air charging pipe and an air charging valve. A pressure relief valve is installed in a bypass manner beside the air charging pipe. After the airbag is inflated, under the action of buoyancy, the guide seats and the magnet bar are driven to be located at the top of the cutting fluid. After the airbag is depressurized, under the action of gravity, the guide seats and the magnet bar move downward to adsorb and remove the chips blocked on the filter holes of the filter plates, and carry the chips to the bottom side of the filter plates.

[0012] Anti-slip patterns are arranged on the surface of the magnet bar. On one side of the magnet bar, a corresponding driving gear is fixedly connected. On the filter plate, a fixed rack adapted to the driving gear is fixedly connected. During the movement of the magnet bar, the driving gear meshes with the fixed rack to drive the magnet bar to rotate.

[0013] On the baffle at the bottom of the filter plate, a pulling spring for pulling the guide seat is fixedly connected.

[0014] Liquid level sensors are respectively installed in the flow area and the filtering area of the longitudinal filtering cavity. When the liquid level sensor first detects that the liquid level height of the cutting fluid in the flow area is higher than the liquid level height of the cutting fluid in the corresponding filtering area by a set value L1, the pressure relief valve is opened, and the guide seats and the magnet bar move downward to adsorb and remove the chips blocked on the filter holes of the filter plates. When the liquid level sensor secondarily detects that the liquid level height of the cutting fluid in the flow area is higher than the liquid level height of the cutting fluid in the corresponding filtering area by the set value L1, the machine is stopped to manually clean the filter plates and the chips on the magnet bar.

[0015] A corresponding closed top plate is installed at the top of the cutting fluid diversion channel.

[0016] Advantages of the present invention: 1) The oil stain removal component of the present invention includes an oil stain removal motor, and a set of transmission discs whose output shaft ends are drivingly connected and extend through the bottom side into the cutting fluid diversion channel. The set of transmission discs is made of elastic plates, and an oil stain adsorption material layer is fixedly connected to the outer side surface of the set of transmission discs in a V shape. Further, the present invention is also provided with a lifting float body, and a transmission wheel whose position corresponds to the bottom end of the transmission disc is rotatably installed on the lifting float body. When the lifting float body floats on the top of the cutting fluid, it can drive the transmission wheel to fixedly abut against the bottom end of the set of transmission discs and form an upward driving force on the bottom end of the transmission discs, so that the bottom ends of the set of transmission discs passing through the transmission wheel are bent outwards, thereby making the oil stain adsorption material layer largely located on the top of the cutting fluid, so as to expand the contact rate between the oil stain adsorption material layer and the oil stains floating on the surface of the cutting fluid, thereby effectively and greatly improving the controllability of oil stain removal, so as to efficiently remove the oil stains floating on the surface of the cutting fluid.

[0017] 2) After the oil stain adsorption material layer of the present invention adsorbs the oil stains, it can continuously pass through the scraping plate with the rotation of the transmission disc. Under the action of the scraping plate, the oil stains can be effectively scraped off, so as to ensure that the oil stain adsorption material layer can continuously adsorb and remove the oil stains floating on the surface of the cutting fluid, thereby effectively ensuring the practical effect of the present invention.

[0018] 3) A number of longitudinal filtering chambers are arranged in the cutting fluid diversion channel of the present invention. The longitudinal filtering chambers are divided into a circulation area and a filtering area from front to back. The filter includes a filter plate detachably inserted between the circulation area and the filtering area. Corresponding baffles are respectively folded forward on both sides and the bottom of the filter plate, and corresponding U-shaped clamping plates are fixedly connected to the front ends of the baffles in a T shape. Corresponding covers are fixedly connected to the tops of the filter plate, the baffles and the U-shaped clamping plates. The filter can be integrally pulled out of the longitudinal filtering chamber through the cover, so as to facilitate the cleaning of the chips blocked on the filter plate; and the setting of the U-shaped clamping plate can not only facilitate the fixed insertion of the whole filter, but also form an accommodating space in connection with the filter plate and the baffles to collect the dropped chips, so as to prevent a large amount of chips from falling into the longitudinal filtering chamber when the whole filter is pulled out, and thus the chips blocked on the filter can be conveniently and efficiently and fully discharged.

[0019] 4) On both sides of the U-shaped clamping plate of the present invention, corresponding guide seats are movably installed between the U-shaped clamping plate and the corresponding filter plates. A corresponding connecting plate is fixedly connected between the tops of the guide seats, and a magnet bar arranged in a shaft shape is rotatably installed between the middles of the guide seats. A corresponding airbag is fixedly connected to the upper side of the connecting plate. After the airbag is inflated, under the action of buoyancy, the guide seats and the magnet bar are driven to be located on the top of the cutting fluid. After the airbag is deflated, under the action of gravity, the guide seats and the magnet bar move downward to adsorb and remove the chips blocked on the filter holes of the filter plates and carry the chips to the bottom side of the filter plates. Through the intervention of the magnet bar, manual cleaning can be replaced to remove the chips blocked on the filter plates once, thereby prolonging the interval of manual cleaning and reducing the frequency of personnel operations.

[0020] 5) Anti-slip grooves are arranged on the surface of the magnet bar of the present invention, and a driving gear is fixedly connected to one side of the magnet bar. A fixed rack adapted to the driving gear is fixedly connected to the filter plate. During the movement of the magnet bar, the driving gear meshes with the fixed rack to drive the magnet bar to rotate. This is because some chips are in a spiral long strip shape, so they cannot be removed completely only by the adsorption force. Through the above improvement, the chips can be wound during the adsorption and fixation process, thereby effectively ensuring the removal effect of the spiral long strip-shaped chips.

[0021] 6) A pulling spring for pulling the guide seat is fixedly connected to the baffle at the bottom of the filter plate of the present invention to ensure that the guide seats and the magnet bar can move downward smoothly when the airbag is deflated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings: Embodiment 1: refer to Figures 1-6 A cutting fluid filter device for a machine tool comprises a cutting fluid guide channel 1 for guiding the cutting fluid generated by the machine tool, and a filter 2 arranged on the cutting fluid guide channel 1 for filtering the chips in the circulating cutting fluid; the cutting fluid filter device also comprises an oil removal component 3, and the oil removal component 3 comprises: The oil removal motor 301 is fixedly mounted on the upper part of the discharge end of the cutting fluid guide channel 1. The output shaft end of the oil removal motor 301 is drivingly connected to a group of driving discs 302 extending from the bottom side to the cutting fluid guide channel 1. The group of driving discs 302 is made of elastic plates, and the outer side surface of the group of driving discs 302 is V-shaped and fixed with an oil adsorption material layer 303. The lifting float 304 can be raised and lowered on the lower side of the bottom end of the transmission disc 302 under the guidance of the corresponding limiting mechanism. A transmission wheel 305 corresponding to the bottom end of the transmission disc 302 can be rotatably installed on the lifting float 304. The lifting float 304 floats on the top of the cutting fluid to drive the transmission wheel 305 to be fixedly abutted against a group of bottom ends of the transmission disc 302 and to form an upward driving force on the bottom ends of the transmission disc 302. The bottom ends of a group of the transmission discs 302 are bent outward under the drive of the transmission wheel 305 and are located on the top of the cutting fluid.

[0032] The oil stain removal component 3 of the present invention includes an oil stain removal motor 301, and a set of transmission discs 302 whose output shaft end is drivingly connected and extends through the bottom side into the cutting fluid diversion channel 1. The set of transmission discs 302 is made of elastic plates, and an oil stain adsorption material layer 303 is fixedly connected to the outer side surface of the set of transmission discs 302 in a V shape. Further, the present invention is further provided with a lifting float 304, and a transmission wheel 305 whose position corresponds to the bottom end of the transmission disc 302 is rotatably installed on the lifting float 304. When the lifting float 304 floats on the top of the cutting fluid, it can drive the transmission wheel 305 to fixedly abut against the bottom end of the set of transmission discs 302 and form an upward driving force on the bottom end of the transmission disc 302, so that the bottom end of the set of transmission discs 302 passing through the transmission wheel 305 bends outwards, thereby making the oil stain adsorption material layer 303 largely located on the top of the cutting fluid, so as to expand the contact rate between the oil stain adsorption material layer 303 and the oil stains floating on the surface of the cutting fluid, thereby effectively and greatly improving the controllability of oil stain removal, so as to efficiently remove the oil stains floating on the surface of the cutting fluid.

[0033] A cover 4 for isolating the set of transmission discs 302 is arranged on one side of the oil stain removal motor 301. A scraping plate 5 for scraping the oil stains adsorbed by the oil stain adsorption material layer 303 is arranged on the cover 4, and a material guiding groove 7 for discharging the scraped oil stains into a corresponding oil storage box body 6 is further arranged on the cover 4.

[0034] After the oil stain adsorption material layer 303 adsorbs the oil stains, it can continuously pass through the scraping plate 5 along with the rotation of the transmission disc 302. Under the action of the scraping plate 5, the oil stains are effectively scraped off, so as to ensure that the oil stain adsorption material layer 303 can continuously adsorb and remove the oil stains floating on the surface of the cutting fluid, thereby effectively ensuring the practical effect of the present invention.

[0035] The limiting mechanism adopts a set of fixed columns 8, and a fixed hanging ring 9 sleeved on the fixed columns 8 is fixedly connected to the lifting float 304.

[0036] A plurality of longitudinal filtering chambers 10 are provided in the cutting fluid diversion channel 1. The longitudinal filtering chambers 10 are divided into a circulation area 1001 and a filtering area 1002 from front to back. The filter 2 includes a filter plate 201 detachably inserted between the circulation area 1001 and the filtering area 1002. A plurality of filtering holes are provided in the middle of the filter plate 201. The circulation area 1001 of the longitudinal filtering chamber 10 on one side of the feed end of the cutting fluid diversion channel 1 is connected to the discharge end of the corresponding cutting fluid collection tank 11. Between two adjacent longitudinal filtering chambers 10, the filtering area 1002 of the previous longitudinal filtering chamber 10 is connected to the circulation area 1001 of the next longitudinal filtering chamber 10. The filtering area 1002 of the longitudinal filtering chamber 10 on one side of the discharge end of the cutting fluid diversion channel 1 is connected to the feed end of the corresponding oil outlet chamber 12. The oil outlet chamber 12 is pumped to the feed end of the machine tool cutting fluid feeding mechanism. The oil stain removing assembly 3 is fixedly installed on the upper part of the oil outlet chamber 12.

[0037] Corresponding baffles 202 are respectively turned forward and folded on both sides and the bottom of the filter plate 201. The front end of the baffle 202 is fixedly connected with a corresponding U-shaped clamping plate 203 in a T shape forward. A corresponding cover plate 204 is fixedly connected to the tops of the filter plate 201, the baffle 202 and the U-shaped clamping plate 203. Corresponding slots 13 are respectively inclined between the circulation area 1001 and the filtering area 1002 of the longitudinal filtering chamber 10. The filter plate 201 is inserted between the circulation area 1001 and the filtering area 1002 of the longitudinal filtering chamber 10 by the cooperation of both sides of the U-shaped clamping plate 203 and the corresponding slots 13. The bottom of the U-shaped clamping plate 203 is closed and abuts against the bottom surface of the longitudinal filtering chamber 10.

[0038] In the present invention, a corresponding cover plate 204 is fixedly connected to the tops of the filter plate 201, the baffle 202 and the U-shaped clamping plate 203. The filter 2 can be integrally pulled out of the longitudinal filtering chamber 10 through the cover plate 204, so as to facilitate the cleaning of the chips clogged on the filter plate 201. The setting of the U-shaped clamping plate 203 can not only facilitate the fixed insertion of the whole filter 2, but also form an accommodating space in connection with the filter plate 201 and the baffle 202 to collect the dropped chips, thereby preventing a large amount of chips from falling into the longitudinal filtering chamber 10 when the whole filter 2 is pulled out, and further enabling the chips clogged on the filter 2 to be fully discharged conveniently and efficiently.

[0039] A corresponding closed top plate 25 is installed on the top of the cutting fluid diversion channel 1.

[0040] Embodiment Two: Reference Figures 7-8, the difference between this embodiment and the first embodiment is that: corresponding guide seats 14 are respectively movably installed between the two sides of the U-shaped clamping plate 203 and the corresponding filter plates 201. A corresponding connecting plate 15 is fixedly connected between the tops of the guide seats 14. And a magnet bar 16 arranged in an axial shape is rotatably installed between the middle parts of the guide seats 14. A corresponding airbag 17 is fixedly connected to the upper side of the connecting plate 15. The airbag 17 is connected to an external air compressor through a corresponding air charging pipe 18 and an air charging valve 19. A pressure relief valve 20 is installed in parallel to the air charging pipe 18. After the airbag 17 is inflated, it drives the guide seats 14 and the magnet bar 16 to be located at the top of the cutting fluid under the action of buoyancy. After the airbag 17 is depressurized, under the action of gravity, the guide seats 14 and the magnet bar 16 move downward to adsorb and remove the chips blocked on the filter holes of the filter plate 201 and carry the chips to the bottom side of the filter plate 201. Through the intervention of the magnet bar 16, it can replace manual work to clean the chips blocked on the filter plate 201 once, thereby prolonging the interval of manual cleaning and reducing the frequency of personnel operation.

[0041] Anti-slip patterns are provided on the surface of the magnet bar 16, and a corresponding driving gear 21 is fixedly connected to one side of the magnet bar 16. A fixed rack 22 adapted to the driving gear 21 is fixedly connected to the filter plate 201. During the movement of the magnet bar 16, the driving gear 21 meshes with the fixed rack 22 to drive the magnet bar 16 to rotate. This is because some chips are in the shape of spiral strips, so the adsorption force alone cannot remove them in place. Through the above improvement, the chips can be wound during the adsorption and fixation process, thereby effectively ensuring the cleaning effect on the spiral strip-shaped chips.

[0042] A pulling spring 23 that pulls the guide seat 14 is fixedly connected to the baffle 202 at the bottom of the filter plate 201 to ensure that the guide seats 14 and the magnet bar 16 can move downward smoothly when the airbag 17 is depressurized.

[0043] Liquid level sensors 24 are respectively installed in the flow area 1001 and the filtering area 1002 of the longitudinal filtering chamber 10. When the liquid level sensor 24 first detects that the liquid level height of the cutting fluid in the flow area 1001 is higher than the liquid level height of the cutting fluid in the corresponding filtering area 1002 by a set value L1, it can be determined that the filter holes of the filter plate 201 are overly blocked. At this time, the pressure relief valve 20 can be controlled to open, so that the guide seats 14 and the magnet bar 16 move downward to adsorb and remove the chips blocked on the filter holes of the filter plate 201. When the liquid level sensor 24 detects for the second time that the liquid level height of the cutting fluid in the flow area 1001 is higher than the liquid level height of the cutting fluid in the corresponding filtering area 1002 by the set value L1, the machine is stopped to manually clean the chips on the filter plate 201 and the magnet bar 16.

[0044] It should be noted that the implementation principle and the technical effects generated by this embodiment are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding content in the first embodiment.

[0045] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
