Description

Technical Field

[0001] This utility model relates to the field of cutting fluid purification technology, and in particular to a CNC machine tool cutting fluid circulation purification module. Background Technology

[0002] CNC machine tool cutting fluid is an industrial liquid used in CNC machine tool machining processes. It is mainly used for cooling, lubrication, cleaning, and rust prevention to improve machining efficiency, ensure machining quality, and extend tool life. The circulation and purification module is a device used to recycle and purify CNC machine tool cutting fluid. The cutting fluid output by the pump is delivered to various cutting parts of the machine tool through the inlet pipe, while the return pipe is responsible for collecting the used cutting fluid from the cutting area of ​​the machine tool and sending it back to the cutting fluid tank or purification device to complete the circulation. During this process, the filter and separation devices effectively remove small particles, improve the cleanliness of the cutting fluid, and separate oil from the cutting fluid to prevent oil from affecting the performance of the cutting fluid.

[0003] Existing purification modules typically employ a fixed structure. As usage time increases, the filter element may gradually become clogged with impurities, leading to decreased filtration efficiency and reduced cutting fluid flow. Furthermore, if impurities such as metal chips, abrasive particles, and oil cannot be effectively intercepted in the cutting fluid, these impurities will enter the machining area with the cutting fluid, accelerating tool wear, reducing the quality of the machined surface, and potentially even causing workpiece scrap. If it is inconvenient to replace the filter element, it may cause insufficient cutting fluid supply, affecting the normal operation of the machining process.

[0004] Therefore, the filter element in the existing purification module may be clogged by impurities, resulting in decreased filtration efficiency and reduced cutting fluid flow. Unfiltered impurities enter the machining area with the cutting fluid, which will reduce the quality of the machined surface. If it is inconvenient to replace the filter element, it will affect the machining process. A CNC machine tool cutting fluid circulation purification module can be designed, which uses a detachable and replaceable filter component to maintain the normal operation of the machining process. Utility Model Content

[0005] To overcome the problems that existing purification modules may have their filter elements clogged by impurities, leading to decreased filtration efficiency and reduced cutting fluid flow, while unfiltered impurities enter the machining area with the cutting fluid, reducing the quality of the machined surface, and the inconvenience of replacing the filter element will affect the machining process.

[0006] The technical solution of this utility model is as follows: a CNC machine tool cutting fluid circulation and purification module, including a round cover and a tank; a tank for purifying cutting fluid is provided below the round cover, a connecting hole is opened in the middle of the round cover, an oil-water separator is provided below the round cover, and multiple sets of snap-fit ​​holes are opened around the bottom of the round cover, located around the connecting hole. An installation ring plate is installed on the upper end of the oil-water separator, and snap-fit ​​posts are installed at the upper edge of the installation ring plate corresponding to the snap-fit ​​holes. The snap-fit ​​posts drive the installation ring plate to be positioned and snapped with the round cover through the snap-fit ​​holes. Multiple sets of arc-shaped snap-fit ​​grooves are opened around the inner wall of the tank. From top to bottom, a large-pore filter plate, a small-pore filter plate and a filter membrane are arranged on the inner side of the tank. A fixing ring plate is installed on the outside of the large-pore filter plate, the small-pore filter plate and the filter membrane. Multiple sets of arc-shaped snap-fit ​​plates fixedly connected to the fixing ring plate are arranged around the outside of the large-pore filter plate, the small-pore filter plate and the filter membrane.

[0007] Furthermore, two sets of handles are longitudinally installed on the upper end of the round cover, and a connecting tube is provided between the two sets of handles. Multiple sets of insertion holes are opened around the top of the round cover, located around the connecting holes.

[0008] Furthermore, an installation ring is fitted around the end of the connecting tube near the round cover. A plug-in post is installed at the lower edge of the installation ring, corresponding to the plug-in hole. The plug-in post drives the installation ring to be positioned and connected to the round cover through the plug-in hole.

[0009] Furthermore, a circulation pump is installed outside the connecting pipe, and an annular sealing ring is installed at the lower edge of the round cover. The annular sealing ring drives the round cover to fit and connect with the inner wall of the tank.

[0010] Furthermore, the arc-shaped snap-fit ​​plate drives the fixing ring plate to engage with the tank body along the arc-shaped snap-fit ​​groove.

[0011] Furthermore, a liquid outlet pipe is installed at the lower end of the tank.

[0012] Furthermore, a telescopic valve is installed at the connection between the liquid outlet pipe and the tank body, and an electromagnetic control valve is installed on the outer side of the telescopic valve.

[0013] The beneficial effects of this invention are as follows: The cutting fluid continuously circulates within a specially designed tank system. Its purification process is meticulously designed to ensure the cutting fluid remains in optimal condition. Through an oil-water separator cleverly installed beneath the round cover and carefully arranged filter plates inside the tank, impurities and oil stains in the cutting fluid are effectively separated and filtered. After a period of continuous use, to maintain the system's purification efficiency, the round cover of the tank must be opened periodically. Following a predetermined sequence, the oil-water separator must be removed first, followed by the filter plates. These components must be carefully cleaned to thoroughly remove all adhering impurities and deposits, preventing contamination. Accumulation of impurities leads to a decrease in separation and filtration efficiency. This method ensures that the cutting fluid undergoes stable and efficient purification during circulation, guaranteeing its cleanliness. This not only provides an extremely stable cutting environment for CNC machine tool processing but also effectively prevents impurity particles from entering the machining area with the cutting fluid. This avoids potential scratches, wear, and other defects on the workpiece surface caused by these particles. As a result, the machining accuracy and surface quality of the workpiece are significantly improved, and the machine tool can operate continuously and stably. The utilization rate of the equipment is greatly increased, providing a solid guarantee for production efficiency and product quality. Attached Figure Description

[0021] Example 1

[0022] like Figures 1-5 As shown, the CNC machine tool cutting fluid circulation and purification module includes a round cover 1 and a tank 2. The tank 2 for purifying the cutting fluid is located below the round cover 1. A connection hole 103 is provided in the center of the round cover 1. An oil-water separator 109 is located below the round cover 1. Multiple sets of snap-fit ​​holes 112 are arranged around the bottom of the round cover 1, surrounding the connection hole 103. An installation ring plate 110 is installed on the upper end of the oil-water separator 109. Snap-fit ​​posts 111 are installed at the upper edge of the installation ring plate 110, corresponding to the snap-fit ​​holes 112. The snap-fit ​​posts 111 drive the installation ring plate 110 through... The cover 1 is positioned and engaged with the snap-fit ​​hole 112. Multiple sets of arc-shaped snap-fit ​​grooves 201 are formed around the inner wall of the tank body 2. From top to bottom, the inner side of the tank body 2 is provided with a large pore filter plate 202, a small pore filter plate 203 and a filter membrane 204. The large pore filter plate 202, the small pore filter plate 203 and the filter membrane 204 are all equipped with fixing ring plates 205. Multiple sets of arc-shaped snap-fit ​​plates 206 are fixedly connected to the fixing ring plates 205 around the large pore filter plate 202, the small pore filter plate 203 and the filter membrane 204.

[0023] Two sets of handles 101 are longitudinally installed on the upper end of the round cover 1, and a connecting tube 102 is provided between the two sets of handles 101. Multiple sets of insertion holes 104 located around the connecting holes 103 are opened around the top of the round cover 1.

[0024] An installation ring 105 is fitted around one end of the connecting tube 102 near the round cover 1. A plug post 106 is installed at the lower edge of the installation ring 105 corresponding to the plug hole 104. The plug post 106 drives the installation ring 105 to be positioned and connected to the round cover 1 through the plug hole 104.

[0025] A circulation pump 107 is installed on the outside of the connecting pipe 102, and an annular sealing ring 108 is installed at the lower edge of the round cover 1. The annular sealing ring 108 drives the round cover 1 to fit and connect with it along the inner wall of the tank body 2.

[0026] The arc-shaped snap-fit ​​plate 206 drives the fixed ring plate 205 to be positioned and snapped with the tank body 2 along the arc-shaped snap-fit ​​groove 201.

[0027] A liquid outlet pipe 207 is installed at the lower end of the tank body 2. Under the control of the electromagnetic control valve 209, the telescopic valve 208 is gradually opened, so that clean cutting fluid flows through the liquid outlet pipe 207 to the machining position.

[0028] A telescopic valve 208 is provided at the connection between the liquid outlet pipe 207 and the tank body 2. An electromagnetic control valve 209 is installed on the outside of the telescopic valve 208. During the liquid outflow process, the telescopic valve 208 can control the liquid flow rate.

[0029] Driven by the circulating pump 107, the used cutting fluid enters the tank 2 through the connecting pipe 102. It first undergoes preliminary oil-water separation through the oil-water separator 109, then passes through the large-pore filter plate 202 to remove larger impurities, then through the small-pore filter plate 203 to remove smaller impurities, and finally through the filter membrane 204 to remove minute impurities, thus obtaining clean cutting fluid. Then, under the control of the electromagnetic control valve 209, the telescopic valve 208 is gradually opened, allowing the clean cutting fluid to flow to the machining position through the outlet pipe 207. During this process, the telescopic valve 208 can control the liquid flow rate.

[0030] After a period of repeated use, the round cover 1 can be opened, and the oil-water separator 109 and filter plate can be disassembled in sequence for cleaning to maintain their separation and filtration performance. After cleaning, the snap-fit ​​column 111 drives the mounting ring plate 110 to be positioned and snapped into the round cover 1 through the snap-fit ​​hole 112, thus assembling the oil-water separator 109. Then, the arc-shaped snap-fit ​​plate 206 drives the fixing ring plate 205 to be positioned and snapped into the tank 2 along the arc-shaped snap-fit ​​groove 201, completing the assembly of the filter plate. Alternatively, the connecting pipe 102 can be disassembled for maintenance. After maintenance, the connecting pipe 102 passes through the connecting hole 103 and is positioned and connected to the round cover 1. At the same time, the insertion column 106 drives the mounting ring 105 to be positioned and connected to the round cover 1 through the insertion hole 104. Finally, the handle 101 is lifted, and the annular sealing ring 108 drives the round cover 1 to fit against the inner wall of the tank 2, allowing it to continue to be used.
