Description

Technical Field

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

[0002] The CNC machine tool cutting fluid supply system is a core auxiliary system used for the precise supply and circulation management of cutting fluid during CNC machine tool machining. Its core function is to deliver the cutting fluid (a mixture of coolant, lubricant, rust inhibitor, etc.) from the storage device to the machining area, such as the tool-workpiece contact point and the chip washing area, and maintain the performance of the cutting fluid through circulation and purification, ultimately achieving the four major goals of "cooling, lubrication, rust prevention, and cleaning", ensuring machining accuracy, tool life, and workpiece surface quality.

[0003] However, existing CNC machine tool cutting fluid supply systems deliver cutting fluid, but the cutting fluid contains a large amount of metal chips, such as hard spots generated during titanium alloy machining, as well as oil and microorganisms. Existing CNC machine tool cutting fluid supply systems use single-stage paper filter elements, which have low filter precision and cannot intercept particles smaller than 5μm, leading to pipe and nozzle blockage, and the metal chips can easily scratch the workpiece. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a CNC machine tool cutting fluid supply system.

[0005] The purpose of this utility model is achieved as follows: A CNC machine tool cutting fluid supply system includes: a main water tank, on the outside of which a three-stage filtration mechanism and a modular mechanism are provided; the three-stage filtration mechanism includes a first pipe connected to the inside of the main water tank; one end of the first pipe away from the main water tank is connected to a second pipe through a filter element body; the second pipe is connected to one end of a first oil pump; the other end of the first oil pump is connected to the inside of a water storage tank; a third pipe is connected inside the water storage tank; the other end of the third pipe is connected to a second oil pump; the other end of the second oil pump is connected to a central water outlet cutting tool through a water supply pipe; a filter assembly is provided inside the filter element body; the filter assembly consists of a permanent magnet separator, a sintered metal filter element, and a PVDF hollow fiber membrane; the permanent magnet separator, the sintered metal filter element, and the PVDF hollow fiber membrane are fixedly connected by a fixing rod.

[0006] Preferably, the second pipe is provided with a compressed air backflush port, which is connected to the compressed air inlet pipe. The compressed air backflush port is internally connected to a backflush pipe, which faces the filter element body.

[0007] Preferably, a sludge tank is provided at the bottom of the first pipe.

[0008] Preferably, the permanent magnet separator, sintered metal filter element, and PVDF hollow fiber membrane are installed inside the filter element body by bolts.

[0009] Preferably, the modular mechanism includes a first flange, which is fixedly connected to both sides of the filter element body. A second flange is fixedly connected to the outer wall of the first pipe and the second pipe. The first flange and the second flange are mated together. A first semi-ring plate and a second semi-ring plate are clamped on the outside of the first flange and the second flange. Protrusions provided on the inner walls of the first semi-ring plate and the second semi-ring plate are clamped inside the first flange and the second flange. A first mounting seat is fixedly connected to the upper end of the first semi-ring plate. A second mounting seat is fixedly connected to the upper end of the second semi-ring plate.

[0010] Preferably, the outer walls of the first flange and the second flange are provided with sealing rings, and the inner walls of the first semi-ring plate and the second semi-ring plate are provided with sealing rings.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes a combination of a first pipe, a second pipe, a first oil pump, a water storage tank, a third pipe, a second oil pump, a filter element body, a permanent magnet separator, a sintered metal filter element, and a PVDF hollow fiber membrane. Upon starting the first oil pump, cutting fluid is drawn from the main water tank and introduced into the water storage tank through the first and second pipes. Simultaneously, the second oil pump is started, drawing cutting fluid from the water storage tank to the central water outlet cutter through the third pipe. During this process, as the cutting fluid passes through the filter element body, it sequentially passes through the permanent magnet separator, the sintered metal filter element, and the PVDF hollow fiber membrane. The system uses a metal filter element and a PVDF hollow fiber membrane for filtration. The permanent magnet separator has a magnetic field strength of 1.2T, which adsorbs large iron filings and metal powder. The sintered metal filter element has a pore size of μm, which intercepts tiny chips and oil particles. The PVDF hollow fiber membrane can remove bacteria and colloidal substances, thus improving the overall filtration effect and achieving meter-level purification of the cutting fluid. This CNC machine tool cutting fluid supply system uses a gradient three-stage filtration to purify the cutting fluid at the meter level. Combined with compressed air backwashing, it can avoid pipeline blockage and improve the practicality and functionality of the device.

[0012] 2. This utility model modularizes the filter element body through the cooperation of a first flange, a second flange, a first semi-ring plate, a second semi-ring plate, a first mounting base, a second mounting base, and locking bolts. This modularity allows the filter element to be assembled onto the first and second pipes. The first and second flanges are then connected, with the external first and second semi-ring plates secured to them by protrusions. Simultaneously, the first and second mounting bases are connected, and the locking bolts are then installed into the first and second mounting bases, completing the convenient assembly and disassembly / replacement process. This CNC machine tool cutting fluid supply system modularizes the filter unit, facilitating overall disassembly, maintenance, and replacement, thus improving the practicality and convenience of the device.
