Description

[0001] This utility model relates to the technical field of machining equipment, and in particular to a cutting fluid tank chip removal integrated machine and a CNC machining center. Background Technology

[0002] In the current field of CNC machining of automotive aluminum alloy parts, CNC cutting fluid tanks are widely used. However, with the continuous improvement of the precision of machined parts, traditional CNC cutting fluid tanks can no longer meet the requirements of high-precision machining scenarios. In actual production, especially in batch production lines, cutting chips accumulate inside the machine tool along with the cutting fluid, contaminating the product clamping, tool changer, and spindle tool mounting environment, seriously affecting machining accuracy and part output, and even causing delivery risks.

[0003] In addition, some cutting tools used in the machining process, such as titanium alloy tools, are quite sensitive to temperature. Cutting fluid temperatures that are too high or too low will affect the tools. Furthermore, the temperature of the cutting fluid fluctuates greatly with changes in ambient temperature, making it impossible to ensure that the tools are always in good working condition. This results in the final workpiece failing to meet the accuracy requirements and affecting the machining quality. Utility Model Content

Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] like Figures 1 to 4 As shown, the cutting fluid tank and chip removal integrated machine according to the first aspect embodiment of this utility model includes a primary water tank 100, a secondary water tank 200, a drum chip removal module 300, a vortex separation module 400, a linear filtration module 500, and a constant temperature module 600. The primary water tank 100 is located below the secondary water tank 200, and both have independent liquid storage chambers. Since the primary water tank 100 serves as a pre-treatment tank for the secondary water tank 200, its processing capacity is significantly higher than that of the secondary water tank 200. Therefore, the volume of the primary water tank 100 is larger than that of the secondary water tank 200, and its floor space is also larger. When the secondary water tank 200 is stacked on top of the primary water tank 100, because the floor space of the primary water tank 100 is also larger than that of the secondary water tank 200, sufficient space is reserved on the surface of the primary water tank 100 to accommodate other devices.

[0034] Specifically, the drum chip removal module 300 consists of components such as a filter drum, scraper, chip removal plate, liquid inlet 310, liquid outlet, and backwash pump. The filter drum is a rotating cylinder covered with filter material, such as a filter screen. The scraper is installed on one side of the filter drum and contacts its surface. The chip removal plate is located below the filter drum to collect the scraped-off solid impurities. The backwash pump provides backwash pressure.

[0035] During operation, cutting chips enter the sludge tank along with the cutting fluid. Larger chips fall into the waste collection box, while smaller solid impurities (including cutting chips) mix into the cutting fluid. The cutting fluid enters through inlet 310 and is filtered by a rotating filter drum. Solid impurities clog the filter screen. As the filter drum rotates continuously, scrapers constantly contact the outer wall of the drum, scraping off the solid impurities adhering to its surface and causing them to fall onto the chip conveyor plate. Simultaneously, the backflushing pump starts, flushing the filter drum with cutting fluid at a certain pressure from the opposite direction, washing the fine particles clogging the filter screen onto the chip conveyor plate. Driven by a chain conveyor belt, the chip conveyor plate discharges the solid impurities to the chip discharge port 320. A receiving trolley is installed below the chip discharge port 320 to collect the waste.

[0036] Furthermore, the drum chip removal module 300 has a filter chamber inside the primary water tank 100. The filter chamber is connected to the primary water tank 100 through a liquid outlet, so that all the liquid in the filter chamber is discharged to the primary water tank 100 after filtration. In addition, there are multiple liquid outlets. If no liquid enters at the liquid inlet 310, the liquid in the primary water tank 100 will flow back into the filter chamber for further filtration under the rotation of the filter drum.

[0037] Specifically, the vortex separator module 400 consists of components such as a vortex separator, a collection box, and a return pipe 430. The vortex separator has an inflow pipe 410 and a discharge pipe 420. The inflow pipe 410 is connected to the booster pump 700 located in the primary water tank 100, and the discharge pipe 420 is connected to the linear filter module 500. The collection box is located at the bottom of the vortex separator and is connected to the primary water tank 100 through the return pipe 430.

[0038] During operation, the booster pump 700 pressurizes and delivers the liquid in the primary water tank 100 to the inlet pipe 410 of the vortex separator. The vortex separator uses pressure to inject the cutting fluid containing particulate impurities into the cone at high speed along the tangential direction through the rectangular inlet, causing it to spiral downwards and generate an external vortex within the cone. Solid impurities in the liquid are thrown towards the inner wall of the cone by centrifugal force and, under the influence of gravity and the liquid, flow along the inner wall into the collection box. The collection box contains a non-woven fabric filter bag, where solid impurities are trapped on the surface of the filter bag. The liquid flowing with the solid impurities passes through the filter bag and returns to the primary water tank 100 through the return pipe 430. Under the action of the vortex force, the discharge pipe 420 is under negative pressure relative to the inlet pipe 410, allowing the separated liquid to be discharged through the central sleeve from the discharge pipe 420 at the top of the cone.

[0039] Specifically, the linear filtration module 500 has a filter housing, which contains a high-precision filter element or membrane with very small pores, capable of filtering even smaller solid impurities. The filter housing protects the filter element or membrane and provides an inlet pipe 510 and an outlet pipe 520 for installation and connection.

[0040] During operation, the cutting fluid filtered by the vortex separator module 400 enters the linear filter module 500 through the inlet pipe 510. Under pressure, the cutting fluid passes through a high-precision filter element or membrane. Due to the extremely small pore size of the filter element or membrane, solid impurities larger than 20µm are intercepted on the surface of the filter element or membrane, while substances smaller than 20µm can pass smoothly through the outlet pipe 520 into the secondary water tank 200, thereby achieving further filtration of the cutting fluid and ensuring its purity.

[0041] In summary, after the cutting fluid passes through the three-stage filtration process of the drum chip removal module 300, the vortex separation module 400, and the linear filtration module 500, the filtration accuracy of the cutting fluid is significantly improved with each filtration, ultimately reaching a filtration accuracy of 20µm. At this filtration accuracy, secondary contamination of the machining and clamping environment by cutting chips can be avoided.

[0042] In addition, to meet the requirements of high-precision machining, a temperature control module 600 is installed on the secondary water tank 200. The temperature control module 600 can be selected as a combined cooling and heating type, meaning it can both raise and lower the water temperature in the secondary water tank 200. The temperature control module 600 specifically includes a controller, a variable frequency compressor, a variable frequency fan, a condenser, an electronic expansion valve, and a circulation pump. The controller determines whether to perform cooling or heating based on the temperature feedback signal. The variable frequency compressor compresses the refrigerant, and the variable frequency fan accelerates airflow to improve cooling or heating efficiency. The condenser is coiled within the temperature control zone for heat exchange with the cutting fluid, transferring heat to or absorbing heat from the cutting fluid. The electronic expansion valve regulates the refrigerant flow rate, and the circulation pump circulates the refrigerant.

[0043] During operation, the constant temperature module 600 heats or cools the cutting fluid based on its temperature. A temperature sensor monitors the cutting fluid temperature in real time and transmits the signal to the controller. When the controller determines that heating is needed, it starts the variable frequency compressor, variable frequency fan, electronic expansion valve, and circulation pump. The variable frequency compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous state and sends it to the condenser for cooling by the variable frequency fan. After cooling, it becomes a medium-temperature, high-pressure liquid refrigerant, which then enters the dryer filter for filtration and dehumidification. The medium-temperature liquid refrigerant is throttled and depressurized by the electronic expansion valve, becoming a low-temperature, low-pressure gas-liquid mixture. This mixture then absorbs heat from the cutting fluid in the condenser and vaporizes, returning to a gaseous state before returning to the compressor. This cycle repeats to achieve heating. When the controller determines that cooling is needed, it similarly starts the relevant components, but the refrigerant flow and state change are reversed compared to the heating process. The condenser cools the cutting fluid, achieving constant temperature control of the cutting fluid.

[0044] The 600 constant temperature module can cope with production environments with large temperature differences and high-precision machining conditions, effectively reducing the wear and tear of machining tools and ensuring the machining accuracy of the workpieces.

[0045] Of course, in order to circulate the cutting fluid in the secondary water tank 200 to the cutting fluid circulation system of the CNC machining center, the secondary water tank 200 is equipped with a second fluid delivery pump 210. Since some CNC machining centers have multiple machining stations, there are multiple second fluid delivery pumps 210, and each second fluid delivery pump 210 can be controlled independently. The second fluid delivery pump 210 is preferably a high-power water pump, which is equipped with a large-diameter water pipe. The high-flow-rate, high-head high-pressure water pump can ensure that the CNC machining center has sufficient spraying effect during the spraying process.

[0046] In addition, for washing machine bed operations where high precision is not required, the cutting fluid in the secondary water tank 200 is not needed; the cutting fluid in the primary water tank 100 is sufficient. Therefore, the primary water tank 100 is equipped with a first delivery pump 110. Since some CNC machining centers have multiple washing stations, multiple first delivery pumps 110 are used, each of which can be independently controlled. The first delivery pump 110 is preferably a high-power water pump equipped with a large-diameter water pipe; the high-flow-rate, high-head high-pressure water pump ensures that the CNC machining center receives a sufficient washing effect.

[0047] In general, the inlet 310 serves as the inlet terminal of the primary water tank 100, the first infusion pump 110 serves as the outlet terminal of the primary water tank 100, the outlet pipe 520 serves as the inlet terminal of the secondary water tank 200, and the second infusion pump 210 serves as the outlet terminal of the secondary water tank 200.

[0048] In some embodiments of this invention, two linear filter modules 500 are provided, and the inlet pipes 510 of both linear filter modules 500 are connected to the outlet pipe 420. Valves are installed on each pipeline to allow the two linear filter modules 500 to operate alternately. Two linear filter modules 500 are used because the effective operating time of each linear filter module 500 is shorter than that of the vortex separator module 400; therefore, to achieve continuous operation, the two linear filter modules 500 must be used alternately.

[0049] In some embodiments of this utility model, the primary water tank 100 is equipped with a first level gauge 120, and the secondary water tank 200 is equipped with a second level gauge 220. The first level gauge 120 is used to detect the liquid level in the primary water tank 100, and the second level gauge 220 is used to detect the liquid level in the secondary water tank 200, so as to prevent the lack of cutting fluid in the tank due to abnormal conditions, thereby causing dry drilling in the CNC machining center. When any level gauge detects that the liquid level in the tank is lower than the warning value, the system will issue an alarm and stop the machining process.

[0050] In some embodiments of this invention, the primary water tank 100 is equipped with an oil-water separator 130, which can separate oil from cutting fluid and collect the oil. Even if the oil-water separator 130 cannot completely separate all oil from the cutting fluid, because oil and cutting fluid have different densities, the oil will eventually flow back to the primary water tank 100 in the vortex separation module 400 and will not enter the secondary water tank 200.

[0051] In some embodiments of this utility model, the bottom surface of the primary water tank 100 is provided with a roller bracket 140, which includes a roller and a support foot. When it is necessary to fix the position of the primary water tank 100, the screw of the support foot is turned to make the support foot closer to the ground relative to the roller, at which time the roller is supported by the support foot. When it is necessary to move the position of the primary water tank 100, the screw of the support foot is turned to make the support foot farther away from the ground relative to the roller, at which time the roller contacts the bottom surface.

[0052] According to a second aspect of the present invention, a CNC machining center includes a cutting fluid tank and chip removal integrated machine according to the first aspect of the present invention, and further includes a cutting fluid circulation system. The cutting fluid circulation system is connected to the inlet 310, the first pump 110 and the second pump 210. The cutting fluid circulation system is equipped with a temperature sensor (not shown in the figure), and the temperature sensor is electrically connected to the constant temperature module 600.

[0053] The temperature sensor is set synchronously with the machining tool. When the cutting fluid comes into contact with the machining tool, its temperature can be detected by the temperature sensor. The controller compares the actual temperature with the preset temperature and then adjusts the power of the constant temperature module 600 to keep the temperature of the cutting fluid within the control value, thus providing good working conditions for the machining tool.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
