Description

Technical Field

[0001] This invention relates to the field of cutting fluid filtration technology, and more particularly to a cutting fluid filter for machine tools. Background Technology

[0002] Machine tool cutting fluid filters are purifiers for CNC lathes, milling machines, grinding machines, and other equipment. They continuously extract emulsions or synthetic fluids mixed with iron filings, abrasive particles, and oil, and purify them through multiple stages of sedimentation, magnetic separation, paper tape filtration, or centrifugal separation. This removes micron-sized impurities and floating oil, keeping the liquid clear, odorless, and unspoiled. The purified cutting fluid is directly returned to the machine tool's fluid tank for reuse, reducing the frequency of fluid changes and waste discharge. The equipment is equipped with automatic slag discharge, full paper alarm, and liquid level maintenance functions. No dedicated personnel are required for operation. Users only need to connect the inlet and outlet ports, set the filtration accuracy, and start the machine with a single button for long-term automatic operation. This significantly extends tool life, improves the quality of machined surfaces, improves the workshop environment, and reduces production costs.

[0003] Existing machine tool cutting fluid filters generally use a direct extraction method with inserted tubes. Operators need to bend over to open the fluid tank, insert a rigid tube or corrugated tube into the bottom of the storage box, and then adjust the insertion depth based on experience. Moreover, when the cutting fluid is almost completely extracted, the extraction tube needs to be moved frequently to ensure that the cutting fluid and waste are completely extracted. Furthermore, when it is necessary to switch to suction of floating oil, the tube must be pulled out again, the height adjusted, and the operation repeatedly bent over. This is labor-intensive and inefficient.

[0004] Therefore, a cutting fluid filter for machine tools is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] In practical use, it was found that existing machine tool cutting fluid filters generally adopt the method of direct extraction by inserting a tube. Operators need to bend over to open the liquid tank, insert a rigid tube or corrugated tube into the bottom of the storage box 3, and then adjust the insertion depth based on experience. Moreover, when the cutting fluid is almost completely extracted, it is necessary to frequently move the extraction tube to ensure that the cutting fluid and waste residue are completely extracted. In order to solve the above problems, the following structure was invented.

[0031] like Figures 1-9 The machine tool cutting fluid filter shown includes a filter 1, a storage box 3 installed on the machine tool for storing cutting fluid, and a pump assembly 2 installed on the filter 1 for pumping out the cutting fluid. When the filter 1 processes the pumped cutting fluid, the cutting fluid containing waste residue is sent to a vertical filter cylinder by the pump assembly 2. The cylinder is equipped with a wedge-shaped filter screen. The cutting fluid filtered through the filter screen is discharged, while the waste residue remains in the filter screen and can be cleaned after filtration. At the same time, the filter 1 has a floating oil filtration and separation function. The floating oil layer is drawn into an independent chamber, where it is separated by coalescence through an oleophilic and hydrophobic filter element. The clean oil is discharged into a waste oil tank, and the residual trace oil droplets are returned to the machine tool after two-stage filtration by activated carbon and ultrafiltration membrane, completing the floating oil recovery and fine filtration.

[0032] The pump set 2 is driven by a variable frequency motor and equipped with three-way valves at the inlet and outlet. When started, the pump set 2 draws liquid from the machine tool storage box 3 and sends it tangentially to the bottom of the filter cylinder of the filter 1 through the valve, forming an upward swirling flow, which is conducive to the separation of impurities. After filtration, the clear liquid gathers at the top of the cylinder. When the valve is switched, the pump set 2 reverses or bypasses and directly connects, pushing the clean liquid back to the storage box 3 along the return liquid pipeline to complete the circulation. The frequency converter automatically adjusts the speed according to the liquid level signal to realize fully automatic switching of "liquid suction-filtration delivery-return", without the need for manual start and stop.

[0033] Side strips 4 are fixedly connected to both sides of the inner wall of the storage box 3. A transverse frame 5 is provided on the storage box 3. L-shaped frames 7 are fixedly connected to both ends of the side wall of the transverse frame 5. Electric drive wheels 6 are provided on the opposite side of the L-shaped frames 7. The electric drive wheels 6 are composed of a hub motor, a reducer, an encoder and a driver. The controller outputs current according to the path command, the motor generates torque, and after the speed is reduced and the torque is increased by the reducer, it directly drives the wheel rim to rotate. The encoder provides real-time feedback of the speed, realizing differential steering and automatic walking. The L-shaped frame 7 is provided with a clamping mechanism for clamping the electric drive wheels 6 on the storage box 3. An L-shaped plate 8 is slidably connected to the inner side of the transverse frame 5. A main pipe 9 is slidably connected through the L-shaped plate 8. A hose 10 is fixedly connected through the middle of the side wall of the main pipe 9. The other end of the hose 10 is fixedly connected to the extraction end of the pumping unit 2. A transverse mechanism is provided on the transverse frame 5 for driving the L-shaped plate 8 to move laterally. Four upper openings 11 are provided through the outer wall of the main pipe 9. An adjustment mechanism for adjusting the water pumping direction of the main pipe 9 is also provided.

[0034] Four lower openings 12 are provided through the bottom of the outer wall of the main pipe 9. The lower openings 12 ensure that the cutting fluid can be drawn out when the main pipe 9 is in contact with the bottom of the storage box 3. The four upper openings 11 are located above the connection between the hose 10 and the main pipe 9.

[0035] The transverse movement mechanism includes a transverse movement motor 13, which is fixedly connected to the side wall of the transverse movement frame 5. A threaded rod 14 is rotatably connected to the inside of the transverse movement frame 5. The threaded rod 14 is threaded through and connected to the inner side wall of the L-shaped plate 8. The output end of the transverse movement motor 13 passes through the inside of the transverse movement frame 5 and is fixedly connected to the threaded rod 14.

[0036] The clamping mechanism includes bolts 15, and there is a pair of bolts 15. Both bolts 15 are threaded and connected to the top of the L-shaped frame 7. A movable plate 16 is longitudinally slidably connected to the inner side of the L-shaped frame 7. The bottom ends of the bolts 15 are rotatably connected to the top of the movable plate 16. Both sides of the bottom end of the movable plate 16 are fixedly connected to the pressing plate 17. The side walls of the pressing plate 17 are inclined. The side walls of the L-shaped frame 7 are transversely slidably connected to the sliding block 18. The side walls of the sliding block 18 are fixedly connected to the housing of the electric drive wheel 6.

[0037] A return spring 19 is fixedly connected between the side wall of the sliding block 18 and the inner side of the L-shaped frame 7. A groove 20 is opened at the top of the side wall of the sliding block 18. The inclined surface of the groove 20 is in contact with the inclined surface of the extrusion plate 17. A top platform 24 is fixedly connected to the inner side of the storage box 3 and the side close to the electric drive wheel 6. The height of the top platform 24 is set lower than the bottom position of the electric drive wheel 6. It should be noted that the liquid level of the cutting fluid in the storage box 3 cannot exceed the top of the top platform 24. Thus, by setting the top platform 24, the normal movement of the L-shaped frame 7 can be avoided, ensuring that all cutting fluid and waste residue in the storage box 3 can be extracted.

[0038] When extracting cutting fluid from the machine tool, first place the transverse frame 5 on the storage box 3, then rotate the two bolts 15 one by one to move them downwards. This will push the moving plate 16 to slide downwards, thereby driving the two extrusion plates 17 to move downwards. At this time, the inclined surface of the extrusion plate 17 will extrude the inclined groove 20. Since the sliding block 18 can only slide laterally, under the extrusion of the inclined surface of the extrusion plate 17, the sliding block 18 will be pushed to slide outwards. At the same time, the return spring 19 is stretched, and the electric drive wheel 6 will slide to both sides, so that the electric drive wheel 6 is inserted into the side bar 4, and the traveling wheel of the electric drive wheel 6 contacts the side wall of the side bar 4. At this time, the transverse frame 5 is quickly installed on the storage box 3, and the pump group 2 can be started to extract the cutting fluid from the storage box 3.

[0039] During the extraction process, the transverse motor 13 can be started to drive the threaded rod 14 to rotate, which in turn drives the threaded L-shaped plate 8 to slide, thereby driving the main pipe 9 to move and extract all the cutting fluid and waste residue at the bottom of the storage box 3. When the L-shaped plate 8 moves to the end of the threaded rod 14, the electric drive wheel 6 can be controlled to walk on the side bar 4, thereby driving the transverse frame 5 to move, and at the same time driving the main pipe 9 to move. By adjusting the extraction position, the transverse motor 13 can be reversed to drive the main pipe 9 to move laterally. This process is repeated to achieve the extraction of all the waste residue at the bottom of the storage box 3.

[0040] In summary, with the above structural design, simply placing the transverse frame 5 on the machine tool's cutting fluid storage box 3 and locking the position of the electric drive wheel 6 through the clamping mechanism will automatically drive the main pipe 9 to move at the bottom of the storage box 3, thereby achieving automatic extraction of cutting fluid and waste residue. This eliminates the need for workers to manually extract the fluid, improving the flexibility of the device.

[0041] Based on the above embodiments, it was found during use that the above structure can only extract the cutting fluid and waste residue from the bottom of the storage box 3. However, during the use of the cutting fluid, only a thin oil film appears on the surface, while the middle layer remains clear and odorless. When the performance can be restored simply by removing the floating oil, workers still need to hold the oil extraction tube to extract the floating oil on the surface. This is labor-intensive and inefficient. To solve the above problems, the above structure has been further improved.

[0042] Side blocks 23 are fixedly connected to both sides of the inner wall of the storage box 3. The top of the side blocks 23 is inclined. Three floats 38 are fixedly connected at equal intervals to the outer wall of the main pipe 9. The side blocks 23 can block the bottom sides of the storage box 3. Due to the floats 38, the main pipe 9 cannot suck up the waste residue on both sides of the storage box 3. Therefore, the side blocks 23 are set to block the waste residue. The waste residue falling on the side blocks 23 will slide down the inclined surface at the top of the side blocks 23 under its own gravity. Moreover, the side blocks 23 are located above the floats 38, so the complete extraction of waste residue can be ensured without hindering the movement of the floats 38.

[0043] The adjustment mechanism includes an electric telescopic cylinder 21, a top plate 22 fixedly connected to the top of the L-shaped plate 8, an electric telescopic cylinder 21 fixedly connected to the top of the top plate 22, a pull rod 25 slidably connected through the top of the main pipe 9, an upper circular hole frame 26 and a lower circular hole frame 27 fixedly connected to the inner side of the main pipe 9 respectively, the upper circular hole frame 26 and the lower circular hole frame 27 are respectively located on the upper and lower sides of the connection between the hose 10 and the main pipe 9, a sealing block 28 is provided between the upper circular hole frame 26 and the lower circular hole frame 27, the bottom end of the pull rod 25 is fixedly connected to the top of the sealing block 28, an upper block 29 is fixedly connected to the top of the side wall of the main pipe 9, a pull rope 30 is fixedly connected to the bottom of the upper block 29, a guide 31 is fixedly connected to the top of the L-shaped plate 8, a pull block 32 is slidably connected to the top of the L-shaped plate 8, and the other end of the pull rope 30 passes through the guide roller of the guide 31 and is fixedly connected to the side wall of the pull block 32.

[0044] The output end of the electric telescopic cylinder 21 is fixedly connected to the bottom end of the top plate 22 with an L-shaped rod 33. The side wall of the L-shaped rod 33 is fixedly connected to a right-angle plate 34 with an inclined surface. The side wall of the pull block 32 is fixedly connected to a round rod 35. The top end of the pull rod 25 is fixedly connected to a push plate 36. The bottom end of the upper round hole frame 26 is fixedly connected to the outer wall of the sealing block 28 with a compression spring 37.

[0045] When the transverse frame 5 is installed on the storage box 3 to extract the cutting fluid at the bottom, the suction of the pump group 2 will be transmitted through the hose 10. Since the sealing block 28 is blocked in the upper round hole frame 26 at this time, the suction will be transmitted through the lower round hole frame 27 to the bottom of the main pipe 9, and the cutting fluid will be drawn from the lower opening 12.

[0046] When it is necessary to extract the floating oil on the surface of the cutting fluid, first, control the electric telescopic cylinder 21 to start and drive the L-shaped rod 33 and the right-angle plate 34 to slide downward. As the L-shaped rod 33 moves downward, the pushing force on the push plate 36 will be gradually released, and then the compression on the pull rod 25 and the sealing block 28 will be gradually released. Subsequently, under the elastic force of the compression spring 37, the sealing block 28 will be pushed to slide downward. At the same time, the downward movement of the right-angle plate 34 will gradually release the compression on the round rod 35. If the float 38 is below the liquid level line at this time, the main pipe 9 will move upward under the buoyancy of the float 38, and at the same time pull the pull rope 30 to move upward and pull the pull block 32 to slide on the L-shaped plate 8. Then the L-shaped rod 33 moves away from under the push plate 36, completely releasing the pushing force on the pull rod 25. At this time, the compression spring 37 Under the elastic force, the sealing block 28 is pushed to seal in the lower round hole frame 27, and the right angle plate 34 is removed from the round rod 35, which will not restrict the up and down movement of the float 38. Thus, under the action of the float 38, the upper opening 11 will be moved to the upper surface of the cutting fluid (at this time, the main pipe 9 will slide freely up and down on the L-shaped plate 8. It should be noted that since the upper opening 11 is attached to the floating oil layer, it will automatically drop with the liquid level and stop when it is lower than the set height. Retaining the middle layer of clear liquid can maintain the original cooling and lubrication performance of the cutting fluid, avoid pump dry running, concentration imbalance and re-mixing. The control logic is also set to stop pumping in advance, so there is no need and no need to pump out all the cutting fluid in the storage box 3. Therefore, the bottom of the main pipe 9 will not obstruct the normal extraction of floating oil). Then, the pumping pump group 2 is started, and the floating oil on the upper surface of the cutting fluid can be sucked from the upper opening 11.

[0047] When adjustment is needed for bottom extraction of the main pipe 9, the electric telescopic cylinder 21 is activated to pull back the L-shaped rod 33 and the right-angle plate 34. At this time, the L-shaped rod 33 will abut against the push plate 36, restricting the push plate 36 from moving upward. Then, the inclined surface of the right-angle plate 34 will squeeze the round rod 35, driving the pull block 32 and the pull rope 30 to slide. Under the guidance of the guide 31, the pull rope 30 can pull the upper block 29 and the main pipe 9 downward, causing the main pipe 9 to move downward. At this time, the upper round hole frame 26 will be pulled onto the sealing block 28, thereby bringing the bottom of the main pipe 9 into contact with the bottom of the storage box 3 and sealing the upper round hole frame 26, so that the waste residue and cutting fluid at the bottom of the storage box 3 can be completely extracted.

[0048] In summary, the above-described structure not only enables the main pipe 9 to move independently at the bottom of the storage box 3, but also allows for rapid conversion to a floating oil extraction mode to extract and filter the floating oil on the surface of the cutting fluid, improving the flexibility of the device and eliminating the need for workers to continuously extract the floating oil by hand.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0050] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
