[0002] To address issues such as difficult chip removal, chip accumulation scratching the hole surface, easy tool wear, and drill bit chipping during drilling, the cooling method of the machine tool during machining is changed from external cooling to hollow internal cooling. This significantly improves machining results, increases hole machining efficiency, and extends drill bit life. To achieve this, in addition to requiring a hollow water-cooled spindle, internally cooled tools and tool holders, a dedicated filtration system for the hollow water-cooled spindle is also needed. The cutting fluid pressurization device included in this system is a key functional component for achieving high-pressure water output, meeting the machine tool's requirements for high-pressure, clean cutting fluid.

[0003] The existing technology has the following problems: 1) The existing booster device has too limited functionality and poor filtration capacity. It can only meet the filtration requirements of one high-pressure pump and cannot achieve multi-channel cutting fluid filtration. 2) The existing booster device uses a single filter medium and has low filtration accuracy, which cannot meet the different filtration accuracy requirements of multiple cutting fluids; 3) The existing booster unit is not equipped with a backup filter. When the filter medium is replaced, the machine needs to be stopped, which affects the machine tool processing cycle. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional cutting fluid circulation and pressurization device that integrates the ordinary cutting fluid filtration and circulation function with the cutting fluid pressurization function. It can provide machine tools with clean external cooling and low-pressure cutting fluid, as well as high-precision hollow internal cooling and high-pressure cutting fluid. The backup structure can ensure that the cutting fluid supply is not affected when replacing the filter bag or filter element of the filtration system, thereby ensuring the continuous processing of the machine tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional cutting fluid circulation and pressurization device includes a clean fluid tank 1. A bag filter 2, a supply pump 3, a cooling pump 4, a flushing pump 5, a dual-filter assembly 6, a single-filter bottle 7, a high-pressure pump 8, a level sensor 9, and an electrical control box 10 are simultaneously installed on the cover of the clean fluid tank 1.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] This utility model discloses a multifunctional cutting fluid circulation and pressurization device, such as Figure 1 As shown, the system includes a clean liquid tank 1; a bag filter 2, a supply pump 3, a cooling pump 4, a flushing pump 5, a dual filter bottle assembly 6, a high-pressure pump 8, a liquid level sensor 9, and an electrical control box 10 are simultaneously installed on the cover of the clean liquid tank 1; a single filter bottle 7 is installed on the cover of the clean liquid tank 1 via a filter bottle mounting bracket 24 and screws; the bag filter 2 is connected to the single filter bottle 7 via a rubber tube and a manual three-way ball valve 15, and the outlet of the single filter bottle 7 is connected to the clean liquid tank 1 via a rubber tube and a pipe fitting; the dual filter bottle assembly 6 is installed on the cover of the clean liquid tank 1 via a support sheet metal 23 and screws; the supply pump 3 is connected to the inlet of the dual filter bottle assembly 6 via a rubber tube and a pipe fitting, and the outlet of the dual filter bottle assembly 6 is connected to the inlet of the high-pressure pump 8 via a rubber tube and a pipe fitting.

[0022] like Figure 2 As shown, the dual filter bottle assembly 6 includes a differential pressure sensor 12, a check valve 16, a manual three-way ball valve 15, a 20-inch filter bottle 20, a filter element 19, an adjustable sheet metal 21, a differential pressure gauge mounting bracket 22, and a supporting sheet metal 23. The two 20-inch filter bottles 20 are mounted on the supporting sheet metal 23 via the adjustable sheet metal 21 and screws. The two 20-inch filter bottles 20 are connected in parallel. The manual three-way ball valve 15 is installed at the inlet end of the parallel pipeline main line connecting the 20-inch filter bottles 20 via a pipe fitting. Two 20-inch filter bottles 20 are each equipped with a check valve 16 at their branch outlet ends. A differential pressure sensor 12 is connected between the inlet and outlet ends of the parallel pipeline of the 20-inch filter bottles 20. Filter element 19 is installed inside the 20-inch filter bottle 20. A single filter bottle 7 is mounted on the filter bottle mounting bracket 24 with screws. Filter element 29 is installed inside the single filter bottle 7. Pressure gauges 17 are installed at the inlet and outlet of the single filter bottle 7. A pressure sensor 13 is connected to the outlet end of the high-pressure pump 8 through a pipe fitting.

[0023] like Figure 3As shown, a pressure gauge sensor 11 and a manual three-way ball valve 15 are installed at the inlet end of the bag filter 2 via a pipe joint; a filter bag 18 is installed inside the bag filter 2.

[0024] like Figure 4 As shown, an overflow port 25 is welded to the side of the clean liquid tank 1; an electrical control box 10 is installed on the clean liquid tank 1, and a wiring trough sheet metal 26 is arranged on the clean liquid tank 1. The wiring names of each component are printed on the electrical control box 10; a drain port 27 is designed on the clean liquid tank 1, and a plug 30 is screwed into the drain port 27, with a sealing ring between the two; universal casters 28 are installed at the bottom of the clean liquid tank 1 by screws; the outlet of the cooling pump 4 is connected to a flow piping, and a flow sensor 14 is installed on the flow piping.

[0025] The method of using this utility model is as follows: Cutting fluid containing waste chips enters the filter bag 18 inside the bag filter 2 through the inlet of the bag filter 2. The filter bag 18 intercepts and filters the waste chip particles in the cutting fluid, and the cutting fluid enters the clean fluid tank 1 through the filter bag by permeation. When the cooling pump 4 receives a command to start, the cooling pump 4 draws cutting fluid from the clean fluid tank 1 to supply the machine tool. At the same time, the flow sensor 14 on the cooling pump 4 will display the flow data in the pipeline in real time, and will alarm in time when the flow rate does not reach the set value. When the flushing pump 5 receives a command to start, the flushing pump 5 draws cutting fluid from the clean fluid tank 1 to supply the machine tool. When the high-pressure pump 8 receives a command to start, the liquid supply pump 3 draws cutting fluid from the clean fluid tank 1 to supply the double filter bottle assembly 6. After further filtration by the double filter bottle assembly, the cutting fluid enters the high-pressure pump 8, and the high-pressure pump 8 pressurizes the cutting fluid before supplying it to the machine tool.

[0026] The bag filter 2 is equipped with a pressure gauge sensor 11. When the filter bag 18 is clogged and needs cleaning, the pressure gauge sensor 11 will provide an alarm. When the filter bag 18 needs cleaning, the cutting fluid flow direction can be adjusted to the direction of the single filter bottle 7 via the manual three-way ball valve 15. The single filter bottle 7 temporarily replaces the bag filter 2 to perform the filtering function. At this time, cleaning and maintaining the bag filter 2 and the filter bag 18 will not affect the normal supply of cutting fluid. When the dual filter bottle assembly 6 is in use, only one 20-inch filter bottle 20 is in use, and the other is on standby. When the differential pressure sensor 12 detects an abnormal differential pressure value, an alarm will be triggered, indicating that the filter element 19 of the 20-inch filter bottle 20 needs to be replaced. Before replacing the filter element, the cutting fluid flow direction can be adjusted to the direction of the standby 20-inch filter bottle 20 via the manual three-way ball valve 15. At this time, replacing the filter element of the original filter bottle will not affect the normal supply of cutting fluid.

[0027] The liquid level sensor 9 installed on the clean liquid tank 1 can monitor the liquid level in the clean liquid tank 1 in real time. When the liquid level is lower than the set minimum liquid level value, an alarm will be triggered to prompt the addition of liquid. An overflow port 25 is provided on the side of the clean liquid tank 1. When the liquid level in the clean liquid tank 1 is higher than the designed maximum liquid level, it will flow back to the main water tank through the overflow port 25, which plays a foolproof role. A drain port 27 is designed at the bottom of the clean liquid tank 1. When it is necessary to clean the liquid tank or replace the cutting fluid, the liquid can be quickly discharged from the drain port 27.

[0028] This device allows for the selection of filter bags 18 and filter cartridges 19 of different precision according to filtration requirements, thus achieving filtration of varying precision.

[0029] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
