Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid purification devices, specifically a cutting fluid purification device for CNC machine tools. Background Technology

[0002] In the machining of large and medium-sized CNC machine tools, the purification of cutting fluid is becoming increasingly important. This utility model proposes a cutting fluid purification device, which solves the problem of cutting fluid purification in the machining of large and medium-sized CNC machine tools.

[0003] Existing machine tool cutting fluids are generally filtered through a perforated screen, then settled, and finally pressurized and reused by a pump. This method results in poor cooling performance due to the high amount of impurities in the cutting fluid, failing to achieve high machining accuracy. Furthermore, oil often contaminates the cutting fluid, causing it to deteriorate, produce an unpleasant odor, and have a very short service life. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a CNC machine tool cutting fluid purification device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a CNC machine tool cutting fluid purification device, comprising a water tank, an inlet installed at one end of the upper surface of the water tank, a coarse filter screen installed at the bottom of the inlet, a paper tape filter installed on the upper surface of the water tank near the inlet, the outlet pipe of the paper tape filter being inserted into the water tank, the water tank being divided into chamber I, chamber II, chamber III and chamber IV by partition plates, two partition plates being provided, each with a partition wall opening, a magnetic rod filter installed in chamber II near the partition wall opening, and an external cooling pump and an internal cooling pump installed on the outer wall of the water tank in chamber IV.

[0006] Preferably, a level gauge is installed inside the III cavity.

[0007] Preferably, a pipe filter is installed on the outer wall of the water tank near the internal cooling pump, and the pipe filter is connected to the internal cooling pump via pipes.

[0008] Preferably, an oil separator is provided on the outer wall of the water tank within cavity I.

[0009] Preferably, a slag box is fixedly installed on the outer wall of the water tank near the paper tape filter.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Large impurities in the cutting fluid are coarsely filtered through a coarse filter screen, then filtered a second time using the filter paper of a paper belt filter, and finally filtered a third time by adsorbing extremely fine iron filings onto the magnetic rods using a magnetic rod filter. Compared with the existing method of filtering and settling only through a porous screen, this method can more effectively remove impurities of different sizes, improve the purity of the cutting fluid, and thus improve the cooling effect and machining accuracy.

[0012] 2. The oil separator output end is equipped with an oil-absorbing film that extends deep into the top of the I chamber. This film can absorb floating oil, scrape off surface oil, prevent the cutting fluid from deteriorating due to oil mixing, prevent the generation of unpleasant odors, and extend the service life of the cutting fluid.

[0013] 3. An internal cooling pump and an external cooling pump are installed in the IV cavity. A pipeline filter is added to the internal cooling pump pipeline to achieve a purification level of more than 10μm, which greatly improves the filtration accuracy of the cutting fluid. This lays a good foundation for the machine tool to produce parts with good surface finish and high precision, and extends the service life of the cutting tools and cutting fluid.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-2 As shown, this utility model provides a CNC machine tool cutting fluid purification device, including a water tank 1. An inlet 16 is installed at one end of the upper surface of the water tank 1. Used cutting fluid flows into the water tank 1 through the inlet. A coarse filter screen 10 is installed at the bottom of the inlet 16. A paper tape filter 3 is installed on the upper surface of the water tank 1 near the inlet 16. The paper tape filter 3 is automatically paper-changing. When impurities in the cutting fluid accumulate and clog the filter screen, the cutting fluid forms a small pool and floats the float on the filter paper. A sensor switch activates the filter belt to move. The filter paper is replaced automatically until the small pool disappears, the float returns to its original position, and the mesh belt stops moving. This cycle achieves automatic filter paper replacement. The liquid outlet pipe of the paper belt filter 3 is inserted into the water tank 1. The water tank 1 is divided into chamber I 11, chamber II 12, chamber III 13 and chamber IV 14 by partition plates 15. There are two partition plates 15, each with a partition wall opening. A magnetic rod filter 8 is installed in chamber II 12 near the partition wall opening. An external cooling pump 4 and an internal cooling pump 6 are installed on the outer wall of the water tank 1 in chamber IV 14.

[0020] A level gauge 7 is installed in the III cavity 13. The level gauge 7 monitors the amount of cutting fluid entering the III cavity 13 from the I cavity 11 and the II cavity, and monitors it in a timely manner to estimate the subsequent discharge volume.

[0021] A pipeline filter 5 is installed on the outer wall of the water tank 1 near the internal cooling pump 6. The pipeline filter 5 is connected to the internal cooling pump 6 via pipelines. The pipeline filter is added to the pipeline of the internal cooling pump 6 to achieve a purification degree of more than 10μm. In order to facilitate the direct spraying of the cutting fluid through the pipe hole in the machine tool cutting machine, the external cooling pump 4 can directly extract the cutting fluid that enters the IV chamber 14 and then spray it directly onto the workpiece being cut through the output pipe.

[0022] An oil remover 2 is installed on the outer wall of the water tank 1 inside cavity I 11. An oil-absorbing film is installed at the output end of the oil remover 2, and the output end extends into the top of cavity I 11 to absorb the floating oil, thereby scraping off the floating oil on its surface.

[0023] A slag box 9 is fixedly installed on the outer wall of the water tank 1 near the paper tape filter 3. The slag box 9 is mainly used to collect the used filter paper in the paper tape filter 3.

[0024] Working principle: During use, the cutting fluid flowing from the machine tool is introduced into the inlet 16 through the pipe. First, it passes through the coarse filter screen 10 set at the bottom of the inlet 16. The coarse filter screen 10 mainly retains large impurities in the cutting fluid on the screen for coarse filtration. Then, the cutting fluid flows to the filter paper of the paper belt filter 3 for filtration. The filter paper in the paper belt filter 3 will filter the cutting fluid through the filter paper by gravity, thus performing secondary filtration of the cutting fluid.

[0025] Subsequently, after filtration, it enters cavity I 11 and flows through the partition wall opening set on the partition plate 15 to cavity II 12. There is a magnetic rod filter 8 at the partition wall opening in cavity II 12. The purpose of the magnetic rod filter 8 is to adsorb extremely fine iron filings onto the magnetic rod for three filtrations. In cavity I 11, the output end of the oil remover 2 is equipped with an oil suction film. The output end extends into the top of cavity I 11 to adsorb floating oil, thereby scraping off the floating oil on its surface and making the cutting fluid cleaner.

[0026] The cutting fluid then flows into cavity III 13 through the partition wall opening on partition plate 15. After sedimentation in cavity III 13, it enters cavity IV 14 to obtain pure cutting fluid. Cavity IV 14 is equipped with internal cooling pump 6 and external cooling pump 4. The internal cooling pump 6 has a pipeline filter added to achieve a purification degree of more than 10μm, so that it can be directly sprayed out through the pipe hole in the machine tool for subsequent cutting. The external cooling pump 4 can directly extract the cutting fluid entering cavity IV 14 and then spray it directly onto the workpiece being cut through the output pipe.

[0027] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
