Description

Technical Field

[0001] The invention relates to the technical field of cutting fluid filtration for machine tool processing, in particular 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. It can be recycled under fully filtered conditions.

[0003] Existing cutting fluid filtering devices for machine tools generally include a transfer container and a filter arranged in the transfer container. After the chips in the cutting fluid are effectively filtered out by the filter, the cutting fluid is recycled. Since the oil stains existing in machining are often mixed into the cutting fluid during recycling, thus affecting the normal use of the cutting fluid, an overflow mechanism is generally added to the existing transfer container to overflow and discharge the oil stains floating on the surface of the cutting fluid, thereby achieving the removal of the oil stains. Such cutting fluid filtering devices for machine tools have the following defects during actual use: 1) The controllability of oil stain removal is insufficient. It is often the case that the oil stains are not removed properly or the cutting fluid is treated as oil stains and removed; 2) When the filter is clogged with chips, it is necessary to stop the machine and then manually reach into the cutting fluid to clean the filter in time. Not only is cleaning difficult, but the chips during the cleaning process are also likely to fall into the transfer container, which is very troublesome.

[0004] Therefore, the research purpose of this invention is to design a cutting fluid filter device for machine tools that can effectively and significantly improve the controllability of oil removal, thereby efficiently removing oil floating on the surface of the cutting fluid; and can conveniently and efficiently clear the chips blocked on the filter.

[0018] A corresponding closed top plate is installed on the top of the cutting fluid guide channel.

[0019] Advantages of the present invention:

[0020] 1) The oil removal assembly of the present invention includes an oil removal motor, the output shaft end of which is in driving connection with a group of drive discs extending from the bottom side into the cutting fluid guide channel. The group of drive discs is made of elastic sheet material, and the outer side surfaces of the group of drive discs are V-shaped and fixedly connected to an oil adsorption material layer. The present invention further includes a lifting float on which a drive wheel is rotatably mounted, the position of which corresponds to the bottom end of the drive disc. When the lifting float floats on top of the cutting fluid, it can drive the drive wheel to abut against the bottom end of the group of drive discs, generating an upward driving force on the bottom end of the drive discs, causing the bottom end of the group of drive discs rotating past the drive wheel to bend outward, thereby positioning a large area of ​​the oil adsorption material layer on top of the cutting fluid, thereby increasing the contact rate between the oil adsorption material layer and the oil floating on the cutting fluid surface, thereby effectively and significantly improving the controllability of oil removal and efficiently removing the oil floating on the cutting fluid surface.

[0021] 2) After the oil adsorption material layer of the present invention adsorbs the oil, it can continue to pass through the scraper plate as the transmission disc rotates. Under the action of the scraper plate, the oil is effectively scraped off to ensure that the oil adsorption material layer can continue to adsorb and remove the oil floating on the surface of the cutting fluid, thereby effectively ensuring the practical effect of the present invention.

[0022] 3) The cutting fluid guide channel of the present invention is provided with a number of longitudinal filter cavities, which are divided into a circulation area and a filtration area from front to back. The filter includes a filter plate that is detachably inserted between the circulation area and the filtration area. The two sides and the bottom of the filter plate are respectively folded forward to provide corresponding baffles. The front end of the baffle is T-shaped and fixed forward to a corresponding U-shaped card. The tops of the filter plate, baffle and U-shaped card are fixed with corresponding cover plates, and the filter can be pulled out of the longitudinal filter cavity as a whole through the cover plate to facilitate the cleaning of the chips blocked on the filter plate. The setting of the U-shaped card not only facilitates the fixed insertion of the filter as a whole, but also connects with the filter plate and baffle to form a storage space, which can collect the fallen chips, thereby preventing a large amount of chips from falling into the longitudinal filter cavity when the filter is pulled out as a whole, and thus can conveniently and efficiently clear the chips blocked on the filter.

[0023] 4) The present invention features guides movably mounted between the two sides of the U-shaped clamping plate and the corresponding filter plates. A corresponding connecting plate is fixedly attached to the top of the guides, and a shaft-shaped magnet is rotatably mounted in the middle of the guides. A corresponding airbag is fixedly attached to the upper side of the connecting plate. When the airbag is inflated, the buoyancy of the airbag drives the guides and magnet to the top of the cutting fluid. After the airbag is depressurized, gravity forces the guides and magnet downward to remove chips clogged in the filter plate's pores and carry them to the bottom of the filter plate. The magnet replaces manual cleaning of chips clogged in the filter plate, extending the manual cleaning interval and reducing the frequency of manual work.

[0024] 5) The magnet bar of this invention features anti-slip grooves on its surface, and a drive gear is affixed to one side of the magnet bar. A fixed rack compatible with the drive gear is affixed to the filter plate. During the movement of the magnet bar, the drive gear and the fixed rack mesh, driving the magnet bar's rotation. This is because some chips are long, spiral strips that cannot be removed by suction alone. This improvement allows the chips to be entangled during the suction and fixation process, effectively ensuring the removal of these long, spiral chips.

[0025] 6) A pulling spring is fixed to the baffle at the bottom of the filter plate of the present invention to pull the guide seat, so as to ensure that the guide seat and the magnet bar can move downward smoothly when the airbag is depressurized. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] An oil removal motor 301 is fixedly mounted on the upper portion of the discharge end of the cutting fluid guide channel 1.

The drive discs 302 are made of elastic plates. The outer side surfaces of the drive discs 302 are V-shaped and fixedly connected to an oil adsorption material layer 303.

The lifting float 304 floats on the top of the cutting fluid to drive the transmission wheel 305 to be fixedly abutted against the bottom end of a group of the transmission discs 302 and to form an upward driving force on the bottom end of the transmission disc 302. The bottom end of a group of the transmission discs 302 is bent outward under the drive of the transmission wheel 305 and is located on the top of the cutting fluid.

[0040] The oil removal assembly 3 of the present invention includes an oil removal motor 301, the output shaft end of which is connected to a group of transmission discs 302 whose bottom side extends through the cutting fluid guide channel 1. The group of transmission discs 302 are made of elastic plates, and the outer side surfaces of the group of transmission discs 302 are V-shaped and are fixedly connected to an oil adsorption material layer 303. The present invention is further provided with a lifting float 304, on which a transmission wheel 305 is rotatably installed, the position of which corresponds to the bottom end of the transmission disc 302. When the lifting float 304 floats on the top of the cutting fluid, it can drive the transmission wheel 305 to be fixedly abut against the bottom end of a group 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 group of transmission discs 302 rotating through the transmission wheel 305 is bent outward, so that the oil adsorption material layer 303 is located on the top of the cutting fluid with a large area, so as to expand the contact rate between the oil adsorption material layer 303 and the oil floating on the surface of the cutting fluid, thereby effectively and significantly improving the controllability of oil removal, so as to efficiently remove the oil floating on the surface of the cutting fluid.

[0041] A cover 4 is provided on one side of the oil removal motor 301 for isolating a group of the drive discs 302. The cover 4 is provided with a scraper plate 5 for scraping off the oil adsorbed by the oil adsorption material layer 303.

[0042] After the oil adsorption material layer 303 adsorbs the oil, it can continue to pass through the scraper plate 5 as the transmission disc 302 rotates. Under the action of the scraper plate 5, the oil is effectively scraped off to ensure that the oil adsorption material layer 303 can continue to adsorb and remove the oil floating on the surface of the cutting fluid, thereby effectively ensuring the practical effect of the present invention.

[0043] The limiting mechanism adopts a group of fixed columns 8, and the lifting float 304 is fixedly connected with a fixed hanging ring 9 sleeved on the fixed columns 8.

[0045] The two sides and the bottom of the filter plate 201 are respectively folded forward to provide corresponding baffles 202, the front end of the baffle 202 is T-shaped and fixed forward to a corresponding U-shaped card plate 203, and the tops of the filter plate 201, the baffle 202 and the U-shaped card plate 203 are fixed with corresponding cover plates 204; corresponding slots 13 are respectively obliquely provided between the flow area 1001 and the filtration area 1002 of the longitudinal filter cavity 10, and the filter plate 201 is inserted between the flow area 1001 and the filtration area 1002 of the longitudinal filter cavity 10 by cooperating with the corresponding slots 13 on both sides of the U-shaped card plate 203, and the bottom of the U-shaped card plate 203 is closed and abuts against the bottom surface of the longitudinal filter cavity 10.

[0046] The tops of the filter plate 201, baffle 202 and U-shaped card plate 203 of the present invention are fixedly connected with corresponding cover plates 204, and the filter 2 can be pulled out of the longitudinal filter cavity 10 as a whole through the cover plate 204, so as to facilitate the cleaning of the chips blocked on the filter plate 201; and the setting of the U-shaped card plate 203 not only facilitates the fixed insertion of the filter 2 as a whole, but also can be connected with the filter plate 201 and the baffle 202 to form a accommodating space, which can collect the fallen chips, thereby preventing a large amount of chips from falling into the longitudinal filter cavity 10 when the filter 2 is pulled out as a whole, and thus can conveniently and efficiently clear the chips blocked on the filter 2.

[0047] A corresponding closed top plate 25 is installed on the top of the cutting fluid guide channel 1 .

[0048] Example 2:

[0049] refer to Figure 7-8, the difference between this embodiment and the first embodiment is that: corresponding guide seats 14 are movably installed between the two sides of the U-shaped clamping plate 203 and the corresponding filter plate 201, and corresponding connecting plates 15 are fixed between the tops of the guide seats 14, and a magnet rod 16 arranged in an axial shape is rotatably installed between the middle parts of the guide seats 14, and a corresponding air bag 17 is fixed to the upper side of the connecting plate 15. The air bag 17 is connected to the external air compressor through a corresponding inflation pipe 18 and an inflation valve 19, and a pressure relief valve 20 is installed in the bypass of the inflation pipe 18; after the air bag 17 is inflated, the guide seat 14 and the magnet rod 16 are driven to the top of the cutting fluid under the action of buoyancy. After the air bag 17 is depressurized, the guide seat 14 and the magnet rod 16 move downward under the action of gravity 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. The intervention of the magnet bar 16 can replace manual labor to clear the chips blocked on the filter plate 201, thereby extending the manual cleaning time interval and reducing the frequency of human operations.

[0050] The surface of the magnet bar 16 is provided with anti-slip grooves, and a corresponding drive gear 21 is fixed to one side of the magnet bar 16. A fixed rack 22 adapted to the drive gear 21 is fixed to the filter plate 201. During the movement of the magnet bar 16, the drive gear 21 meshes with the fixed rack 22 to drive the magnet bar 16 to rotate. This is because some chips are in the form of spiral strips, which cannot be removed by suction alone. With this improvement, the chips are simultaneously wrapped during the suction and fixation process, effectively ensuring the removal of spiral chips.

[0051] A pulling spring 23 is fixedly connected to the baffle 202 at the bottom of the filter plate 201 to pull the guide seat 14, so as to ensure that the guide seat 14 and the magnet bar 16 can move downward smoothly when the air bag 17 is depressurized.

[0052] Corresponding liquid level sensors 24 are respectively installed in the circulation area 1001 and the filtration area 1002 of the longitudinal filter chamber 10. When the liquid level sensor 24 detects for the first time that the liquid level of the cutting fluid in the circulation area 1001 is higher than the liquid level of the cutting fluid in the corresponding filtration area 1002 and reaches the set value L1, it can be determined that the filter holes of the filter plate 201 are excessively blocked. At this time, the pressure relief valve 20 can be controlled to open, so that the guide seat 14 and the magnet rod 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 of the cutting fluid in the circulation area 1001 is higher than the liquid level of the cutting fluid in the corresponding filtration area 1002 and reaches the set value L1, the machine is stopped and the chips on the filter plate 201 and the magnet rod 16 are manually cleaned.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
