Description

Technical Field

[0001] This utility model relates to the field of CNC machining coolant production technology, and in particular to a filter structure for CNC machining coolant production. Background Technology

[0002] CNC machining coolant, also known as cutting fluid, is an industrial liquid used in metal cutting, grinding, and other machining processes to cool and lubricate cutting tools and workpieces, while also serving a cleaning and rust-preventing function. It is often referred to as the "blood" of machining, crucial for ensuring machining quality, improving machining efficiency, and extending tool life. CNC machining coolant has four core functions: first, cooling, which removes cutting heat to prevent overheating and deformation of the workpiece and tool; second, lubrication, which reduces friction between the tool and chips to lower power consumption and wear; third, cleaning, which washes away fine chips and abrasive particles to prevent scratching the workpiece surface; and fourth, rust prevention, which prevents the workpiece, machine tool, and cutting tool from rusting in the machining environment. In addition, modern cutting fluids often contain functional additives such as bactericides. Choosing a suitable cutting fluid requires comprehensive consideration of factors such as the machining materials, process type, machining requirements, and cost. Furthermore, its environmental treatment after use is receiving increasing attention.

[0003] Existing CNC machining coolant requires a certain amount of raw materials during production, which limits the amount that can be added. As the amount of raw materials increases, incomplete reaction and material precipitation inevitably occur. The precipitated material is discharged along with the finished cutting fluid, thus reducing the quality of the produced cutting fluid. To address this, a filtration structure for CNC machining coolant production is proposed. Utility Model Content

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] For this embodiment, please refer to Figures 1-4 The present invention relates to a filtration structure for producing coolant for CNC machining, comprising a storage tank 1, a filter assembly, and a cleaning assembly. The filter assembly is located in the middle of the inner side of the storage tank 1, and the cleaning assembly is installed inside the filter assembly. A boss 2 is provided in the middle of the bottom surface of the inner side of the storage tank 1. The filter assembly includes a fixed filter cylinder 3 and a movable filter cylinder 4. The fixed filter cylinder 3 is fixedly located on the top surface of the boss 2, and the movable filter cylinder 4 is rotatably located in the middle of the inner side of the fixed filter cylinder 3. The cleaning assembly includes a movable brush 5 and a fixed brush 6. The movable brush 5 is fixed on both sides of the outer circular surface of the movable filter cylinder 4, and the end of the movable brush 5 away from the movable filter cylinder 4 is in contact with the inner circular surface of the fixed filter cylinder 3. The fixed brush 6 is fixedly located at both ends of the inner circular surface of the movable filter cylinder 4, and the fixed brush 6 is in contact with the inner circular surface of the movable filter cylinder 4. A drive motor 7 is provided inside the boss 2, and the output rod of the drive motor 7 rotates synchronously with the bottom surface of the movable filter cylinder 4. Specifically, when the coolant enters the storage tank 1 through the pouring funnel 14, the precipitates in the coolant caused by insufficient reaction will directly contact the movable filter cylinder 4, thereby filtering out the larger precipitates through the movable filter cylinder 4, while the smaller precipitates will contact the fixed filter cylinder 3 along with the coolant, thus achieving a second filtration effect. When the fixed filter cartridge 3 and the movable filter cartridge 4 become clogged, the drive motor 7 can be turned on. The drive motor 7 drives the movable filter cartridge 4 to rotate. While rotating, the movable brushes 5 at both ends drive the movable brushes 5 to clean the sediment attached to the fixed filter cartridge 3. The inner side of the rotating movable filter cartridge 4 will come into contact with the fixed brushes 6, and the cleaning effect will be carried out simultaneously. It should be noted that the filter holes on both the fixed filter cylinder 3 and the movable filter cylinder 4 are circular, but they can also be square or hexagonal, etc. No specific limitation is made here. The attached drawings are only for illustration and are not intended to limit the actual structure and pore size of the filter holes on the fixed filter cylinder 3 and the movable filter cylinder 4. Those skilled in the art should be able to make reasonable selections and designs according to the actual situation, as long as the fixed filter cylinder 3 and the movable filter cylinder 4 can effectively block the sediment.

[0014] The temporary storage tank 1 has an installation port 8 in the middle of its top surface. The installation port 8 communicates with the inside of the temporary storage tank 1. The lower end of the side wall of the installation port 8 is provided with a misaligned sliding groove 9. The two ends of the top surface of the installation port 8 are provided with installation slots 10 that communicate with the misaligned sliding groove 9. The installation port 8 is provided with a detachable positioning installation ring 11. The bottom surface of the positioning installation ring 11 abuts against the top surface of the fixed filter cylinder 3. The two ends of the positioning installation ring 11 are provided with installation blocks 12 that match the installation slots 10 near the misaligned sliding groove 9. Specifically, during installation, after the fixed filter cylinder 3 and the movable filter cylinder 4 are placed into the temporary storage tank 1, the positioning installation ring 11 is inserted into the installation slot 10, and then the positioning installation ring 11 is rotated to drive the installation block 12 into the misaligned sliding groove 9 for locking. It should be noted that the rotation direction of the drive motor 7 is the same as the rotation direction of the mounting block 12 when it rotates into the misaligned slide groove 9. This is to prevent the fixed plate 15 from driving the positioning mounting ring 11 to rotate due to the friction generated when the fixed brush 6 and the movable filter cylinder 4 rotate, which would cause the mounting block 12 to come out of the misaligned slide groove 9.

[0015] The positioning mounting ring 11 has positioning slots 13 at both ends of its middle section. The positioning mounting ring 11 has a pouring funnel 14 in its middle section. The lower end of the pouring funnel 14 has a fixing plate 15 that matches the middle section of the positioning mounting ring 11. The two ends of the fixing plate 15 have fixing protrusions 16 that match the positioning slots 13 near their respective positions. The bottom surface of the pouring funnel 14 is connected to the inner side of the temporary storage bucket 1. The bottom surface of the fixing plate 15 has a connecting rod 17 near the fixing brush 6. The connecting rod 17 is fixedly connected to the fixing brush 6. Specifically, during installation, the fixing plate 15 is driven by the connecting rod 17 to insert the fixing brush 6 into the movable filter cylinder 4, and at the same time, the fixing protrusion 16 is inserted into the positioning slot 13 to achieve positioning installation.

[0016] The top edge of the boss 2 is provided with an annular groove 18. An upper spring 19 is fixedly installed in the annular groove 18. The top surface of the upper spring 19 is provided with an ejector plate 20. The top surface of the ejector plate 20 abuts against the bottom surface of the fixed filter cylinder 3. The inner bottom surface of the fixed filter cylinder 3 is provided with a rotating platform 21. Positioning blocks 22 are provided at each of the four points on the top surface of the rotating platform 21. The bottom surface of the movable filter cylinder 4 is provided with a notch 23 that matches the positioning block 22 near the positioning block 22. Specifically, during disassembly, after the mounting block 12 comes out of the misaligned slide groove 9, the upper spring 19 loses the limiting effect of the positioning mounting ring 11, the upper spring 19 resets, and the fixed filter cylinder 3, the movable filter cylinder 4 and the rotating table 21 are moved upward, making it convenient for staff to directly remove and replace them without having to put their bodies into the temporary storage bucket 1.

[0017] The rotating platform 21 has an upper connecting protrusion 24 at the center of its bottom surface, which is connected to the drive motor 7. The output shaft of the drive motor 7 has a lower connecting protrusion 25 that complements the upper connecting protrusion 24. The upper connecting protrusion 24 passes through the fixed filter cylinder 3 and the boss 2 and is detachably engaged with the lower connecting protrusion 25. Specifically, during installation, the upper protrusion 24 will cooperate with the lower protrusion 25 to transmit the driving force of the drive motor 7, thereby enabling the rotating table 21 and the movable filter cylinder 4 to rotate.

[0018] The lower end of the outer side of the temporary storage bucket 1 is provided with an outlet 26 near the lower end of the boss 2, and the outlet 26 is connected to the inner side of the temporary storage bucket 1.
