Description

Technical Field

[0001] This utility model relates to the field of CNC milling machine cutting fluid filtration technology, and in particular to a cutting fluid filtration device for CNC milling machines. Background Technology

[0002] CNC milling machine cutting fluid filtration is a device or method used to filter impurities and particles in CNC milling machine cutting fluid. In order to keep the cutting fluid clean, reduce the frequency of replacement, and thus reduce costs, it is necessary to filter the cutting fluid. Therefore, a CNC milling machine cutting fluid filtration device is used.

[0003] To address this, patent CN213555570U discloses a cutting fluid filtration device for CNC milling machines, comprising a first semi-cylinder, a second semi-cylinder, and a connecting ring. Annular grooves are respectively formed on the inner walls of the first and second semi-cylinders on opposite sides. The connecting ring is engaged within the annular grooves on the first and second semi-cylinders. A double-layer filter screen is fixed to the inner wall of the connecting ring. Positioning rings are respectively fixed to the outer walls of the first and second semi-cylinders on opposite sides, and the two positioning rings are fixed by bolts and nuts. Threaded joints are respectively fixed at the midpoint of the opposite sides of the first and second semi-cylinders. Through holes are respectively formed at the midpoint of the opposite sides of the first and second semi-cylinders, corresponding to the threaded joints. This invention has the advantages of filtering out particulate impurities from the cutting fluid and is easy to install and disassemble.

[0004] Although the above-mentioned CNC milling machine cutting fluid filtration device can be replaced by separating the first and second semi-cylinders and removing the connecting ring and filter screen, it is difficult to separate them during use. This makes it difficult to separate larger impurities and iron filings, and it is prone to clogging, resulting in low applicability during use. Utility Model Content

[0005] The purpose of this invention is to provide a cutting fluid filtration device for CNC milling machines, which solves the problem of inconvenient separation in existing cutting fluid filtration devices for CNC milling machines.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cutting fluid filtration device for CNC milling machines, comprising a base plate and a filter box;

[0007] Fixed casters are evenly fixed on both sides of the bottom end of the base plate, a filter box is fixed on one side of the top end of the base plate, and a push handle is fixed on the other side of the top end of the base plate.

[0008] The top of the filter box is provided with a separation structure, the inside of the filter box is fixed with a support frame, and the top of the support frame is provided with a filter structure.

[0009] A drain pipe is fixed to one side of the bottom of the filter box.

[0010] When using this device, the separation structure facilitates its separation, thereby improving its applicability in use; the filtration structure facilitates its filtration, thus enhancing its ease of use.

[0011] Preferably, the bottom of the filter box is designed to be inclined, and a drain valve is installed on the outside of the drain pipe. The inclined design of the bottom of the filter box facilitates draining.

[0012] Preferably, the separation structure includes a separation frame, magnets, a first filter screen, a channel, a sliding plate, and a handle. The separation frame is located on the top of the base plate. Magnets are fixed to both sides inside the separation frame. A channel runs through the bottom of the separation frame, and a first filter screen is located at the top of the channel. Handles are fixed to both sides of the top of the separation frame, and sliding plates are evenly fixed to the outer side of the bottom of the separation frame. By moving the separation frame to the top of the filter box using the handles and pressing the separation frame, the separation frame moves the sliding plate into the channel. Cutting fluid is poured into the interior of the separation frame, and under the action of the first filter screen, larger impurities are retained at the top of the first filter screen.

[0013] Preferably, the filter box on one side of the slide plate has a sliding groove inside, and the slide plate and the filter box form a sliding structure through the sliding groove. Under the action of the magnet, larger iron filings can be attracted, and the separated cutting fluid falls into the interior of the fixed frame through the channel, thereby reducing the chance of clogging. By pulling the handle, the separation frame and the filter box are separated from each other, making it convenient to clean the impurities and iron filings inside the separation frame.

[0014] Preferably, the filter structure includes a fixed frame, a second filter screen, a magnetic material layer, a mixed fiber layer, a limiting groove, and a limiting post. The fixed frame is disposed at the top of the supporting frame. The magnetic material layer is fixed inside the fixed frame. The second filter screen is fixed inside the fixed frame at the top of the magnetic material layer. The mixed fiber layer is fixed inside the fixed frame at the bottom of the magnetic material layer. Limiting grooves are evenly provided at the bottom of the fixed frame, and limiting posts are provided inside each limiting groove.

[0015] Preferably, handles are fixed on both sides of the top of the fixed frame, and the limiting post and the fixed frame form a sliding structure through the limiting groove. By moving the fixed frame into the filter box through the handles, the limiting post moves into the limiting groove, thereby limiting the fixed frame to the top of the support frame, preventing displacement of the fixed frame during filtration. Under the action of the second filter screen, larger impurities can be filtered out.

[0016] Preferably, the bottom end of the limiting post extends to the outside of the fixing frame and is fixedly connected to the top end of the supporting frame, and the limiting posts are evenly distributed at the top end of the supporting frame. Under the action of the magnetic material layer, metal particles in the cutting fluid can be adsorbed, and under the action of the mixed fiber layer, tiny impurity particles are further filtered, improving the quality of the recovered cutting fluid.

[0017] The present invention provides a cutting fluid filtration device for CNC milling machines, the advantages of which are:

[0018] By incorporating a separation structure, the separation frame can be moved to the top of the filter box using the handle. Pressing the separation frame causes it to move the sliding plate into the chute, allowing the cutting fluid to be poured into the separation frame. Under the action of the first filter screen, larger impurities remain at the top of the screen. Under the action of the magnet, larger iron filings can be adsorbed. The separated cutting fluid falls into the fixed frame through the channel, thus reducing the chance of clogging. Pulling the separation frame with the handle separates it from the filter box, facilitating the cleaning of impurities and iron filings inside the separation frame. This device achieves the function of easy separation, thereby improving the applicability of the cutting fluid filtration device for CNC milling machines.

[0019] By incorporating a filtration structure, the fixed frame can be moved into the filter box via a handle, causing the limiting post to move into the limiting groove. This limits the fixed frame to the top of the supporting frame, preventing displacement during filtration. The second filter screen removes larger impurities, while the magnetic material layer adsorbs metal particles from the cutting fluid. The mixed fiber layer further filters out smaller impurities, improving the quality of the recovered cutting fluid. This design facilitates filtration and enhances the ease of use of the CNC milling machine cutting fluid filtration device. Attached Figure Description

[0028] Reference Figure 3 and Figure 5 As shown, by moving the separation frame 301 to the top of the filter box 2 using the handle 306, and pressing the separation frame 301, the separation frame 301 moves the sliding plate 305 into the inside of the slide groove. The cutting fluid is poured into the inside of the separation frame 301. Under the action of the first filter screen 303, larger impurities are kept at the top of the first filter screen 303. Under the action of the magnet 302, larger iron filings can be adsorbed. The separated cutting fluid falls into the inside of the fixed frame 801 through the through groove 304, thereby reducing the chance of clogging.

The fixed frame 801 is located at the top of the support frame 7. A magnetic material layer 803 is fixed inside the fixed frame 801. The second filter screen 802 is fixed inside the fixed frame 801 at the top of the magnetic material layer 803. The bottom of the magnetic material layer 803 is fixed... The fixed frame 801 has a mixed fiber layer 804 fixed inside. The bottom end of the fixed frame 801 is evenly provided with limiting grooves 805. Each limiting groove 805 is provided with a limiting post 806. Both sides of the top of the fixed frame 801 are fixed with handles.

[0030] Reference Figure 3 and Figure 4 As shown, by moving the fixed frame 801 into the filter box 2 through the handle, the limiting post 806 is moved into the limiting groove 805, thereby limiting the fixed frame 801 to the top of the supporting frame 7, preventing the fixed frame 801 from shifting during filtration. Under the action of the second filter screen 802, larger impurities can be filtered out. Under the action of the magnetic material layer 803, metal particles in the cutting fluid can be adsorbed. Under the action of the mixed fiber layer 804, smaller impurity particles are further filtered out, improving the quality of the recovered cutting fluid.
