Description

Technical Field

[0001] The present invention belongs to the field of operation and maintenance of numerical control machine tools, and particularly relates to a cutting fluid recovery device for operation and maintenance of numerical control machine tools. Background Art

[0002] Cutting fluid plays a crucial role in the machining process. It can not only cool the cutting tool, but also lubricate and clean the workpiece, thereby improving production efficiency and workpiece accuracy. However, during use, cutting fluid will be contaminated by metal particles and track oil, resulting in deterioration and waste treatment.

[0003] However, cutting fluid contains impurities such as metal debris (such as aluminum powder, iron filings) and bacterial clumps. When using a conventional filter screen (mesh number ≤ 200), the pressure difference of the filter element can reach 0.5 MPa after continuous operation for 8 hours, and it is necessary to frequently stop the machine for replacement. The functions of the cutting fluid recovery device are few. After the cutting fluid treated by the cutting fluid recovery device removes metal chips, other sundries are still mixed in the cutting fluid, resulting in that the cutting fluid treated by the existing cutting fluid recovery device cannot be directly used for machining parts on the machining machine tool. At the same time, a part of the impurities precipitate inside the device and need to be manually maintained regularly. Summary of the Invention

[0004] The purpose of the present invention is to provide a cutting fluid recovery device for operation and maintenance of numerical control machine tools.

[0005] A cutting fluid recovery device for operation and maintenance of numerical control machine tools includes a cleaning housing, an overflow box, a stepping motor, and a circulation pump. The bottom end of the cleaning housing is connected through a liquid discharge end. An overflow box is arranged on one side of the cleaning housing. Disassembly mechanisms are arranged on both sides of the cleaning housing. The disassembly mechanisms disassemble and replace the hardware arranged outside the separation mechanism according to the usage requirements. A stepping motor is connected to one side of the cleaning housing;

[0006] An oil removal mechanism is arranged on the other side of the cleaning housing. The oil removal mechanism separates and removes the oil inside the cutting fluid, thereby reducing the oil content in the cutting fluid. A slag receiving tray is arranged below the other side of the cleaning housing;

[0007] A separation mechanism is arranged inside the cleaning housing. The separation mechanism adsorbs metal powder or metal wire in the cutting fluid, and at the same time reduces the flow rate of the cutting fluid to remove impurities from the cutting fluid. A cleaning mechanism is arranged inside the oil removal mechanism. The cleaning mechanism reciprocates inside the oil removal mechanism to clean the sediment in the oil removal mechanism, reducing the difficulty of sewage discharge and maintenance. A circulation pump is arranged outside the oil removal mechanism;

The guide rail boxes are symmetrically arranged on both sides of the cleaning housing. Corresponding chutes are opened at the installation corresponding positions of the cleaning housing and the guide rail box.

[0009] Preferably, the bushing is connected to the outside of the guide rail box through the slider connected to the outside.

[0010] Preferably, the degreasing mechanism includes a treatment tank, a transmission box body, a centrifugal cylinder, a servo motor, a driving sprocket, a driven sprocket, a pawl, and a transmission shaft. The transmission box bodies are symmetrically arranged inside the treatment tank. The outside of the transmission box body is connected through the transmission shaft. The outside of the transmission shaft is connected with a centrifugal cylinder. The servo motor is installed outside the treatment tank. The output end of the servo motor is connected with the transmission shaft. The outside of the transmission shaft is connected with a driving sprocket. A driven sprocket is arranged on the other side of the driving sprocket. Multiple groups of pawls are annularly connected to the outside of the driving sprocket.

[0011] Preferably, the transmission box body is connected to one end of the centrifugal cylinder through the driven sprocket arranged inside. The rotation speed range of the 2 groups of centrifugal cylinders is 2000 - 8000 rpm.

[0012] Preferably, the separation mechanism includes a stainless steel filter screen, positioning rods, flow - blocking vanes, electromagnet sheets, guide grooves, positioning holes, and rollers. The stainless steel filter screen is wound around the outside of the 2 groups of rollers. The rollers are installed outside the cleaning housing. Guide grooves are opened on both sides of the cleaning housing. Multiple groups of positioning rods are connected to the outside of the guide grooves. Multiple groups of flow - blocking vanes are arranged at the bottom ends of the positioning rods. Electromagnet sheets are adhesively arranged directly above the positioning rods. Positioning holes are equidistantly opened on the outside of the positioning rods. The other end of the cleaning housing is communicated with the position directly above the slag - receiving tray body through a funnel. A soft brush roller is arranged on the other side of the stainless steel filter screen.

[0013] Preferably, the cleaning mechanism includes a brush holder, side brush rods, card slots, flexible brush strips, ball screws, guide rods, and ratchets. The brush holder is arranged inside the treatment tank. The side brush rods are symmetrically clamped on both sides of the brush holder. Card slots are symmetrically opened on the outside of the brush holder. Flexible brush strips are adhesively connected to the outside of the card slots. Ball screws are connected through the outside of the brush holder. Guide rods are symmetrically opened on the outside of the brush holder. Both sides of the guide rods are connected to the outside of the transmission box body.

[0014] Preferably, the ball screw is connected to the outside of the ratchet pawl through a ratchet wheel connected to one side of the shaft.

[0015] Preferably, the brush holder is connected to the inside of the treatment tank through a ball screw connected to the outside, and the flexible brush strip connected to the outside of the brush holder is attached to the outside of the centrifuge cylinder.

[0016] The advantages of the present invention are as follows:

[0017] 1. The cleaning structure, ratchet pawl and ratchet wheel provided in the present invention constitute a one-way motion control structure. When the gear rotates forward, the ratchet pawl slides on the tooth surface of the ratchet wheel and cannot effectively engage with the ratchet wheel, so the ratchet wheel cannot be driven to rotate; when the gear rotates in reverse, the ratchet pawl is embedded in the tooth groove of the ratchet wheel, and the two engage, so that the ratchet wheel can be driven to rotate. The combination of the ratchet pawl and ratchet wheel can accurately achieve one-way transmission, and only drives the ratchet wheel and the lead screw when the gear rotates in reverse, which can effectively avoid the interference of ineffective actions during forward rotation, ensure that the cleaning brush works at a specific time period according to the set requirements, and make the trigger and operation logic of the entire cleaning action clear and accurate.

[0018] 2. The driving sprocket uses a chain and a driven sprocket for rotation. The combination of the driving sprocket and the driven sprocket can achieve efficient power transmission. When the sprocket rotates, the driven sprocket is driven by the chain, and the power can be stably and quickly transmitted to the centrifuge cylinder, ensuring that the centrifuge cylinder can obtain sufficient power for rotational separation operation. The sprocket drive structure is relatively compact, occupies less space, and is beneficial to the miniaturization of the overall equipment and the optimization of the space layout.

[0019] 3. By slowing down the flow rate of the cutting fluid through the flow blocking plate, the cutting fluid has a more sufficient residence time at the filter screen, and impurities such as metal wires can come into contact with the electromagnet more fully and be adsorbed and separated, improving the separation accuracy of the metal wires and the cutting fluid. At the same time, the flow blocking plate enables the metal wires to be effectively adsorbed by the electromagnet, avoiding the metal wires from winding around the surface of the filter screen and causing blockage, ensuring the smooth flow of the cutting fluid, maintaining the stable operation of the equipment, improving the separation accuracy of the metal wires and the cutting fluid, and reducing the metal wire impurities remaining in the cutting fluid.

The outside of the guide rail box 401 is connected through the push rod 402. The tail end of the push rod 402 is threadedly connected to the nut 406. The outside of the push rod 402 is connected to the bushing 404. The bushing 404 is symmetrically arranged on both sides of the roller 807. The outside of the push rod 402 is connected through the return spring 405. One side of the return spring 405 is adhesively connected to the guide rail box 401. The outside of the guide rail box 401 is symmetrically connected to the slider 403. The guide rail box 401 is symmetrically arranged on both sides of the cleaning housing 1. Corresponding chutes are opened at the installation corresponding positions of the cleaning housing 1 and the guide rail box 401; the bushing 404 is connected to the outside of the guide rail box 401 through the slider 403 connected to the outside.

[0040] The oil removal mechanism 6 includes a treatment tank 601, a transmission box body 602, a centrifugal cylinder 603, a servo motor 604, a driving sprocket 605, a driven sprocket 606, a pawl 607 and a transmission shaft 608.

Multiple groups of pawls 607 are annularly connected to the outside of the driving sprocket 605; the transmission box body 602 is connected to one end of the centrifugal cylinder 603 through the driven sprocket 606 provided inside. The rotational speed range of the 2 groups of centrifugal cylinders 603 is 2000 - 8000 rpm. The purification of the cutting fluid by the centrifugal cylinder 603 is mainly achieved through the centrifugal force separation principle. Its core is to use the centrifugal force generated by high-speed rotation to separate the impurities in the cutting fluid from the liquid, thereby achieving the purification purpose;

[0041] The separation mechanism 8 includes a stainless-steel filter screen 801, positioning rods 802, flow-blocking vanes 803, electromagnet sheets 804, guide grooves 805, positioning holes 806, and rotating rollers 807. The stainless-steel filter screen 801 is wound around the outside of two groups of rotating rollers 807. The rotating rollers 807 are installed on the outside of the cleaning housing 1. Guide grooves 805 are provided on both sides of the cleaning housing 1. A plurality of groups of positioning rods 802 are connected to the outside of the guide grooves 805.

Positioning holes 806 are provided at equal intervals on the outside of the positioning rods 802.

The centrifugal force generated by rotation can accelerate the movement of impurities towards the outside of the filter screen, improving the filtration efficiency, especially having a more significant effect on cutting fluid with a high concentration of impurities. The impurities attached to the surface of the filter screen are carried to a specific area (such as the top or side) by rotation, and the surface of the stainless-steel filter screen 801 is scrubbed by the soft brush roller 11 and then falls onto the surface of the slag receiving tray body 7.

[0042] The cleaning mechanism 9 includes a brush holder 901, side brush rods 902, card slots 903, flexible brush strips 904, ball screws 905, guide rods 906, and ratchets 907.

Ball screws 905 penetrate and connect to the outside of the brush holder 901. Guide rods 906 are symmetrically provided on the outside of the brush holder 901. Both sides of the guide rods 906 are connected to the outside of the transmission housing 602; the ball screws 905 are connected to the outside of the ratchet pawl 607 through ratchets 907 connected to one side of the shaft; the brush holder 901 is connected to the inside of the treatment tank 601 through the ball screws 905 connected to the outside thereof, and the flexible brush strips 904 connected to the outside of the brush holder 901 are in contact with the outside of the centrifugal cylinder 603.

[0043] Working principle:

[0044] Impurity removal steps: The operator first directly injects the cutting fluid into the interior of the cleaning housing 1. The stepping motor 5 provided on the outside drives the roller 807 to rotate, and the roller 807 drives the stainless steel filter screen 801 connected to the outside to rotate around the axis. The cutting fluid flows in from the outside or inside of the filter screen. At the same time, by pulling the positioning rod 802, multiple groups of positioning rods 802 are displaced outside the guide groove 805, so that multiple groups of positioning rods 802 and multiple groups of flow-blocking vanes 803 are displaced. The flow-blocking vanes 803 slow down the flow rate of the cutting fluid, so that the cutting fluid has a more sufficient residence time at the filter screen. The overflow box body 3 discharges the overflowed cutting fluid through a flange on one side, and it can be introduced into the interior of the treatment tank 601;

[0045] The operator turns on the electromagnet sheet 804, and the electromagnet sheet 804 provides magnetic force for the positioning rod 802 and the flow-blocking vane 803. Impurities such as metal wires can come into contact with the electromagnet more fully and be adsorbed and separated. After being separated, the cutting liquid directly precipitates at the bottom of the cleaning housing 1. Then, after the precipitated cutting fluid is preliminarily filtered through the drain end 2, it is introduced into the interior of the treatment tank 601;

[0046] The operator turns on the servo motor 604, and the servo motor 604 drives the driving sprocket 605 to rotate. The driving sprocket 605 drives the driven sprocket 606 provided on the other side through the chain on the outside for transmission processing. The driving sprocket 605 and the driven sprocket 606 rotate, and the centrifugal cylinder 603 is driven to rotate by the transmission shaft 608 provided outside the driving sprocket 605 and the driven sprocket 606. The cutting fluid containing impurities is pumped into the interior of the centrifugal cylinder 603 through the inlet. The centrifugal cylinder 603 rotates at a high speed of 2000 - 6000 rpm (up to more than 10000 rpm for some industrial-grade equipment), forming a strong centrifugal field. The impurities move towards the inner wall of the centrifugal cylinder 603 due to the centrifugal force and adhere to the inner wall or are intercepted by the filter screen; the cleaning fluid converges towards the center;

[0047] Disassembly and maintenance steps: By rotating the nut 406, the nut 406 is disassembled from the tail end of the ejector rod 402 and one side of the guide rail box 401. Subsequently, by pulling one of the rollers 807 connected to both sides of the bushing 404 for displacement, the distance between the two rollers 807 is adjusted, and the limit on the stainless steel filter screen 801 is released, facilitating the disassembly of the connection part of the stainless steel filter screen 801, so that the stainless steel filter screen 801 is taken out from the interior of the cleaning housing 1. When the roller 807 is released, the bushing 404 is pushed by the return spring 405 provided on the outside, so that the rollers 807 connected to both sides of the bushing 404 are reset;

[0048] An alkaline water-based cleaning agent, a solvent-based cleaning agent, and an acidic cleaning agent are injected into the interior of the treatment tank 601 in batches. The operator turns on the servo motor 604 and uses the servo motor 604 to drive the driving sprocket 605 to rotate in the reverse direction. When the driving sprocket 605 rotates in reverse, one of the multiple sets of pawls 607 annularly distributed on the outer side of the driving sprocket 605 is inserted into the tooth groove of the ratchet wheel 907, and the two are engaged, so as to drive the ratchet wheel 907 to rotate. The ratchet wheel 907 is used to drive the ball screw 905 to rotate, and the ball screw 905 is used to drive the brush holder 901 to displace;

[0049] The guide rod 906 penetrating through the outer side of the brush holder 901 is used for lateral guiding treatment. The flexible brush strip 904 arranged on the outer side of the brush holder 901 is used to repeatedly brush the surface of the centrifuge cylinder 603. At the same time, the driving sprocket 605 is used to drive the centrifuge cylinder 603 to rotate in the reverse direction, thereby accelerating the reaction efficiency of the cleaning agent. The circulating pump 10 is used to directly extract the sewage after cleaning, and then directly inject another cleaning agent into the interior of the treatment tank 601. At the same time, the clamping grooves 903 on both sides of the brush holder 901 are used to displace the side brush rods 902. The soft hairs at the bottom ends of the side brush rods 902 are used to brush the bottom end of the treatment tank 601, and the precipitated part of the treatment tank 601 is brushed.

Therefore, the above-disclosed embodiments are illustrative in all aspects and are not exclusive.
