[0026] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort also belong to the protection scope of the present application.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0028] The machine tool of the related art generally only provides a single-layer filtering structure to filter the cutting fluid, and the filtering effect of this solution is poor. Moreover, since no cooling mechanism is provided in the machine tool, the cutting fluid will be heated during the operation of the machine tool, and the cutting fluid circulating through the filtering mechanism has a high temperature, which causes the filtering material in the filtering structure to be deformed or damaged due to the heating, and affects the filtering effect of the filtering structure, the cutting fluid is not filtered clean, and the internal pipeline of the machine tool is easily blocked, which damages the oil pump, the tool and other related devices.

[0029] For a better understanding of the present application, reference will be made by way of example to the accompanying drawings in which: Figures 1 to 4 The machine tool 100 provided by the present application includes a first cutting fluid filtering part 111, a secondary oil tank 12, a main oil tank 13, a filter 14 and a cooling assembly 15. The secondary oil tank 12 is provided with a second cutting fluid filtering part 121, which is adapted to filter the cutting fluid filtered by the first cutting fluid filtering part 111. The main oil tank 13 is connected to the secondary oil tank 12 and the filter 14, and the filter 14 is adapted to filter the cutting fluid filtered by the second cutting fluid filtering part 121. The cooling assembly 15 is assembled in the main oil tank 13, and the cooling assembly 15 is adapted to cool the cutting fluid in the main oil tank 13.

[0030] In this way, the cutting fluid in the machine tool 100 can be subjected to multiple filtering through the first cutting fluid filtering part 111, the second cutting fluid filtering part 121 and the filter 14, which helps to improve the filtering effect of the cutting fluid, improve the cleanliness of the cutting fluid, reduce the blocking inside the machine tool 100, and prolong the service life of the devices in the machine tool 100 such as the oil pump, the tool, the spindle and the like. Moreover, the cooling assembly 15 can cool the cutting fluid, which helps to ensure that the cooling fluid is in a suitable temperature environment, so that the machine tool 100 can meet the demand for high-precision machining, and improve the reliability and stability of the machine tool 100. The filtering precision of the machine tool 100 can be 20 microns or more, which can be set according to actual conditions.

[0031] The machine tool 100 can have a machining part 40 connected to the main oil tank 13 and the secondary oil tank 12, and the cutting fluid can circulate in the machining part 40, the secondary oil tank 12 and the main oil tank 13. The machining part 40 and the secondary oil tank 12 can be connected by a chip removal member 11, for example, the chip removal member 11 can be a chip removal pipe, and the first cutting fluid filtering part 111 can be provided on the chip removal member 11 and face the second cutting fluid filtering part 121. The machining part 40 can be provided with one or more chip removal screws to push the mixture of the machined iron filings and the cutting fluid outwardly toward the chip removal member 11.

[0032] When the machine tool 100 works, the cutting fluid flows through the machining part 40 and carries away the chips generated during the machining of the workpiece. When the cutting fluid flows through the chip removal part 11, the first cutting fluid filtering part 111 can perform primary filtering on the cutting fluid, so that the cutting fluid is separated from most of the iron filings and waste residues. The filtered cutting fluid flows to the auxiliary oil tank 12 and is subjected to secondary filtering under the action of the second cutting fluid filtering part 121. The twice-filtered cutting fluid flows to the main oil tank 13 after being subjected to tertiary filtering under the action of the filter 14, so as to realize multiple filtering of the cutting fluid and improve the cleanliness of the cutting fluid.

[0033] The cooling assembly 15 can cool the cutting fluid, so that the cutting fluid flowing through the machining part 40 can be in a suitable temperature environment. Since the cutting fluid is heated when flowing through the machining part 40 due to absorbing a large amount of heat, the cutting fluid cooled by the cooling assembly 15 can offset a part of the heat absorbed by the cutting fluid, which helps to avoid the cutting fluid being too hot after flowing through the machining part 40, helps to reduce the poor lubrication effect of the high-temperature cutting fluid, and helps to reduce the increase of friction between the parts of the machine tool 100.

[0034] The cooled cutting fluid can be supplied to the spindle of the machine tool 100 for cooling, or supplied to the machining part 40 for machining and cooling of the tool tip and the workpiece, or supplied to the high-pressure center of the spindle for oil / water discharge, or supplied to other parts for flushing and cleaning, which can be set according to actual conditions.

[0035] The machine tool 100 can further include a chip carrier 30. One end of the chip removal part 11 is connected to the machining part 40, and the other end of the chip removal part 11 faces the chip carrier 30. The first cutting fluid filtering part 111 is located between the machining part 40 and the chip carrier 30 and faces the second cutting fluid filtering part 121. When the cutting fluid flows through the chip removal part 11, the first cutting fluid filtering part 111 can filter the cutting fluid. The filtered cutting fluid flows to the auxiliary oil tank 12, and the filtered waste residues flow to the chip carrier 30, so that the chip carrier 30 can concentrate the waste residues to ensure the cleanliness of the working environment of the machine tool 100.

[0036] Please refer to Figures 4 to 6 In some embodiments, the main oil tank 13 is provided with an oil cavity 131, and the filter 14 is located outside the oil cavity 131. The machine tool 100 further includes a first pipeline 16 and a second pipeline 17. The first pipeline 16 penetrates the main oil tank 13. The first pipeline 16 is connected between the outlet end of the auxiliary oil tank 12 and the inlet end of the filter 14. The inlet end of the second pipeline 17 is connected to the outlet end of the filter 14, and the outlet end of the second pipeline 17 is located in the oil cavity 131. The first pipeline 16 can be connected between the outlet end of the oil pump of the auxiliary oil tank 12 and the inlet end of the filter 14, which can be set according to actual conditions.

[0037] Thus, the filter 14 occupies less volume of the oil cavity 131, the effective capacity of the oil cavity 131 is increased, and the filter 14 is convenient to clean and maintain. The first pipeline 16 passes through the main oil tank 13 and is connected to the auxiliary oil tank 12 and the filter 14, which reduces the exposure of the first pipeline 16 to the main oil tank 13 and improves the compactness of the structure of the first pipeline 16 and the main oil tank 13.

[0038] The top of the main oil tank 13 can be provided with an oil injection hole 133, which communicates with the oil cavity 131, so that the machine tool 100 can inject cutting fluid into the oil cavity 131 through the oil injection hole 133. The oil injection hole 133 can be closed by a cover plate, which is opened to open the oil injection hole 133 during use and closed to close the oil injection hole 133 after use.

[0039] Referring to Figure 3 and Figure 4 In some embodiments, the first cutting fluid filter part 111 includes a plurality of filter mesh holes 1111, and the diameter of the plurality of filter mesh holes 1111 is 0.5mm to 20mm.

[0040] Thus, the plurality of filter mesh holes 1111 increases the filtering area of the first cutting fluid filter part 111, improves the filtering effect of the first cutting fluid filter part 111 on the cutting fluid, ensures the appropriate diameter of the filter mesh holes 1111, ensures the filtering effect of the filter mesh holes 1111 on the cutting fluid, ensures the normal flow of the cutting fluid, reduces the possibility of the filter mesh holes 1111 being too large to allow impurities such as iron filings and waste residues to pass through the filter mesh holes 1111, and reduces the possibility of the filter mesh holes 1111 being too small to hinder the flow of the cutting fluid.

[0041] For example, the diameter of the filter mesh holes 1111 can be 0.5mm, 1mm, 1.5mm, 2.5mm, 4mm, 5.8mm, 8mm, 12mm, 15mm, 16.5mm, 18mm, 20mm, or any value between any two adjacent values, which can be set according to actual conditions.

[0042] Thus, the filter mesh holes 1111 can have an appropriate diameter, which ensures the filtering effect of the filter mesh holes 1111 on the cutting fluid and ensures the normal flow of the cutting fluid.

[0043] The second cutting fluid filter part 121 can be provided with a filter sponge and a plurality of filter holes, which can perform secondary filtering on the cutting fluid filtered by the first cutting fluid filter part 111, which can be set according to actual conditions.

[0044] In some embodiments, the filter 14 can be internally provided with a filter bag, for example, the filtering precision of the filter bag can be 20 microns or other values, which can be set according to actual conditions. When the cutting fluid enters the filter 14, the filter bag can filter the cutting fluid again, thereby improving the cleanliness of the cutting fluid.

[0045] In some embodiments, the filter 14 can include a pressure measuring piece 141 and a pressure switch 142, and the filter 14 is provided with a mounting cavity 143, the pressure measuring piece 141 and the pressure switch 142 are both located outside the mounting cavity 143, and the pressure measuring piece 141 and the pressure switch 142 are spaced apart. Wherein, the pressure measuring piece 141 can be a pressure gauge.

[0046] In this way, the pressure measuring piece 141 can detect the pressure inside the filter 14 in real time, facilitate the monitoring of the pressure inside the filter 14, and help to ensure that the filter 14 has a suitable pressure. The pressure switch 142 can warn of abnormal pressure inside the filter to ensure normal operation of the machine tool 100.

[0047] For example, when the filter 14 is blocked, for example, the filter bag is blocked to cause the pressure to rise to a set value, the pressure switch 142 can alarm to prompt the user of the abnormality inside the filter 14, facilitate the user to check and maintain the filter 14 in time, for example, replace a new filter bag, so that the cutting fluid can re-enter the filter 14 for filtering, thereby ensuring the normal operation of the machine tool 100.

[0048] Please refer to Figures 5 to 8 In some embodiments, the cooling assembly 15 includes a cooling piece 151 and a stirring piece 152, and the cooling piece 151 and the stirring piece 152 are both located in the oil cavity 131, and the cooling piece 151 surrounds the outer periphery of the stirring piece 152. Wherein, the cooling piece 151 and the stirring piece 152 can be immersed in the cutting fluid. Wherein, the cooling piece 151 can be a cooling coil.

[0049] Since the heat conduction of the cutting fluid itself is slow, but the oil pumping speed of the oil pump in the machine tool 100 is fast, and the external circulation flow is large, the stirring piece 152 can be rotated to make the cooling piece 151 fully contact with the cutting fluid, which helps to increase the contact area of the cooling piece 151 and the stirring piece 152 with the cutting fluid, improve the cooling efficiency of the cutting fluid, and make the cutting fluid be cooled efficiently and quickly. The cooled cutting fluid can be supplied to the operation of the devices in the machine tool 100, which also helps to reduce the damage of the devices in the machine tool 100 caused by overheating of the cutting fluid, and also helps to reduce the situation that the overheating of the cutting fluid affects the filtering effect of the first cutting fluid filtering part 111, the second cutting fluid filtering part 121 and the filter 14, helps to ensure the filtering effect of the cutting fluid, and also helps to avoid local overheating and overcooling of the cutting fluid, helps to ensure the uniformity of the cutting fluid temperature, and helps to ensure the stability and continuity of the cutting fluid.

[0050] In addition, the cooling piece 151 and the stirring piece 152 are both immersed in the cutting fluid, which also helps to reduce the loss of cold energy, improve the utilization rate of the cold energy of the cooling piece 151, and improve the energy efficiency of the cooling assembly 15.

[0051] In some embodiments, the stirring piece 152 includes a driving body 1521, a driving rod 1522 and a plurality of vanes 1523, the driving rod 1522 is connected to the driving body 1521 and the vanes 1523, and the plurality of vanes 1523 are distributed along the axial direction of the driving rod 1522. The cooling piece 151 is arranged around the outer periphery of the plurality of vanes 1523, and the driving body 1521 is adapted to drive the driving rod 1522 to rotate to drive the plurality of vanes 1523 to rotate synchronously. The driving body 1521 can be a motor, an electric motor or the like.

[0052] In this way, the stirring range of the stirring piece 152 can be increased, the cooling piece 151 can be more fully contacted with the cutting fluid, the uniformity of the cutting fluid temperature can be better ensured, and the cooling efficiency of the cutting fluid can be better improved, so that the cutting fluid can be cooled more efficiently and quickly.

[0053] The plurality of vanes 1523 means two or more, for example, the stirring piece 152 can include two, three, four, five or other number of vanes 1523, which can be set according to actual conditions.

[0054] In some embodiments, the cooling assembly 15 can further include a condenser 153, a compressor 154 and a heat sink 155, all of which are located outside the oil cavity 131, the compressor 154 is connected between the condenser 153 and the cooling member 151, the refrigerant circulates between the compressor 154, the condenser 153 and the cooling member 151, and the heat sink 155 is arranged on the side of the condenser 153 away from the cooling member 151 and is adapted to dissipate heat from the condenser 153.

[0055] In this way, the condenser 153, the compressor 154 and the heat sink 155 occupy less volume of the oil cavity 131, which helps to increase the effective capacity of the oil cavity 131, and facilitates the cleaning and maintenance of the condenser 153, the compressor 154 and the heat sink 155. In addition, the heat sink 155 can dissipate heat from the condenser 153, which helps to ensure that the condenser 153 is in a suitable temperature environment, and the condenser 153 can condense and release heat to exchange heat with the refrigerant, and the cooling member 151 can evaporate and absorb heat to exchange heat with the refrigerant, which helps to ensure the normal operation of the cooling assembly 15.

[0056] In this way, the condenser 153, the compressor 154 and the heat sink 155 occupy less volume of the oil cavity 131, which helps to increase the effective capacity of the oil cavity 131, and facilitates the cleaning and maintenance of the condenser 153, the compressor 154 and the heat sink 155. In addition, the heat sink 155 can dissipate heat from the condenser 153, which helps to ensure that the condenser 153 is in a suitable temperature environment, and the condenser 153 can condense and release heat to exchange heat with the refrigerant, and the cooling member 151 can evaporate and absorb heat to exchange heat with the refrigerant, which helps to ensure the normal operation of the cooling assembly 15.

[0057] The working principle of the cooling assembly 15 is as follows: a target value and a high point value are set in the system, for example, the target value is set to 26℃ and the high point value is set to 29℃, after the machine tool 100 is processed, the temperature of the cutting fluid gradually rises, when the temperature of the cutting fluid reaches 29℃, the compressor 154 starts to cool, the cooling member 151 cools to cool the cutting fluid, and the stirring member 152 rotates to improve the cooling speed of the cutting fluid, at this time the temperature of the cutting fluid begins to drop; when the temperature of the cutting fluid reaches 26℃, the compressor 154, the cooling member 151 and the stirring member 152 stop working to avoid the temperature of the cutting fluid being too low; when the temperature of the cutting fluid rises again, the compressor 154, the cooling member 151 and the stirring member 152 restart to work, and the temperature of the cutting fluid is controlled in this way.

[0058] In some embodiments, the auxiliary oil tank 12 can be provided with a third cutting fluid filter part 122, a fourth cutting fluid filter part 123 and a fifth cutting fluid filter part 124, the first cutting fluid filter part 111, the third cutting fluid filter part 122, the fourth cutting fluid filter part 123, the second cutting fluid filter part 121 and the fifth cutting fluid filter part 124 are sequentially connected, and the filter 14 is adapted to filter the cutting fluid filtered through the fifth cutting fluid filter part 124.

[0059] In this way, the cutting fluid can be filtered through the first cutting fluid filter part 111 and then enter the auxiliary oil tank 12, and then be filtered through the third cutting fluid filter part 122, the fourth cutting fluid filter part 123, the second cutting fluid filter part 121 and the fifth cutting fluid filter part 124 in sequence, which helps to improve the filtering effect of the cutting fluid in the auxiliary oil tank 12, improve the filtering effect of the cutting fluid in the auxiliary oil tank 12, improve the cleanliness of the cutting fluid in the auxiliary oil tank 12, and reduce the plugging inside the auxiliary oil tank 12.

[0060] The third cutting fluid filter part 122 can include a plurality of magnets, which can adsorb iron filings in the cutting fluid filtered by the first cutting fluid filter part 111, and the plurality of magnets can be arranged at intervals. The fourth cutting fluid filter part 123 can be provided with a filter sponge and a plurality of oil filter holes, which can filter the cutting fluid filtered by the third cutting fluid filter part 122 again. The fifth cutting fluid filter part can be a handheld filter screen box provided with a silk screen to filter the cutting fluid filtered by the second cutting fluid filter part 121 again, thereby improving the cleanliness of the cutting fluid.

[0061] The area of the second cutting fluid filter part 121 is greater than the area of the fourth cutting fluid filter part 123, which helps to ensure that the cutting fluid filtered by the fourth cutting fluid filter part 123 can flow into the second cutting fluid filter part 121. The pore diameters of the oil filter holes of the second cutting fluid filter part 121 and the fourth cutting fluid filter part 123 can be equal or unequal, which can be adaptively set according to actual conditions.

[0062] Referring to Figure 5 and Figure 6 In some embodiments, the main oil tank 13 is provided with a sixth cutting fluid filter part 132, which is located in the main oil tank 13 and is adapted to filter the cutting fluid filtered by the filter 14. The sixth cutting fluid filter part 132 can be a filter cartridge.

[0063] In this way, the cutting fluid can be filtered by the filter 14 and then enter the main tank 13, and the sixth cutting fluid filtering part 132 can filter the cutting fluid in the main tank 13, which helps to improve the filtering effect of the cutting fluid in the main tank 13, helps to improve the cleanliness of the cutting fluid in the main tank 13, and helps to reduce the blocking inside the main tank 13.

[0064] The main tank 13 can be provided with a dismounting opening 134 to facilitate manual dismounting of the sixth cutting fluid filtering part 132 through the dismounting opening 134. The dismounting opening 134 can be closed by a cover plate, and the cover plate is opened to open the dismounting opening 134 during use, and the cover plate is opened to close the dismounting opening 134 after use.

[0065] Referring back to Figure 2 and Figure 6 In some embodiments, the machine tool 100 further comprises a first liquid level sensor 18 and a second liquid level sensor 19, the first liquid level sensor 18 is mounted on the auxiliary tank 12, and the second liquid level sensor 19 is mounted on the main tank 13.

[0066] In this way, the first liquid level sensor 18 can detect the liquid level in the auxiliary tank 12, and the second liquid level sensor 19 can detect the liquid level in the main tank 13, which helps to reduce the overflow of the cutting fluid in the auxiliary tank 12 and the main tank 13 due to the high liquid level, and also helps to reduce the damage to the devices in the machine tool 100 due to the low liquid level of the cutting fluid in the auxiliary tank 12 and the main tank 13. The first liquid level sensor 18 can be a float switch, and the first liquid level sensor 18 can also be in other forms, the second liquid level sensor 19 can be a float switch, and the second liquid level sensor 19 can also be in other forms, which can be set according to actual conditions.

[0067] In some embodiments, the machine tool 100 can further comprise a first oil pump 21 mounted in the main tank 13, and the first oil pump 21 can pump the cutting fluid in the main tank 13 to the components in the machine tool 100 that need to use the cutting fluid to ensure the normal operation of the machine tool 100. The sixth cutting fluid filtering part 132 is located at the inlet of the first oil pump 21, so that the sixth cutting fluid filtering part 132 can filter the cutting fluid entering the first oil pump 21 again, which helps to ensure the cleanliness of the cutting fluid entering the first oil pump 21.

[0068] Exemplarily, the first oil pump 21 can be a horizontal high-pressure pump, which can be connected to the main shaft of the machine tool through a pipeline. The first oil pump 21 can pump the cutting fluid in the main oil tank 13 to the main shaft of the machine tool 100 for cooling, thereby ensuring the normal operation of the machine tool 100. In other embodiments, the first oil pump 21 can also be other forms of oil pumps, for example, it can be a vertical pump. The number of first oil pumps 21 can be multiple, for example, the machine tool 100 can include two, three, four or other number of first oil pumps 21, which can be set according to actual conditions to meet the cooling of the main shaft of the machine tool 100, the machining and cutting cooling of the tool tip workpiece, the high-pressure center oil / water outlet of the main shaft, the flushing and cleaning of components at other positions, etc.

[0069] In the embodiment, the oil inlet of the first oil pump 21 can be provided with a switch, for example, a manual ball valve switch or other various forms of automatic switch. In this way, when the first oil pump 21 needs to be repaired or replaced due to failure, the switch can be closed for maintenance and detection, which is convenient to operate.

[0070] In the embodiment, as shown in Figure 6 The main oil tank 13 can be divided into upper and lower two layers.
