Description

Technical Field

[0001] This utility model relates to the field of machine tool coolant supply technology, and in particular to a constant high pressure intelligent fluid control system for machine tools. Background Technology

[0002] During metal cutting, the intense friction between the cutting tool and the workpiece generates a large amount of heat, causing the temperatures of both the workpiece and the cutting tool to rise rapidly. For example, in high-speed milling of steel, the temperature in the cutting zone can instantly reach several hundred degrees Celsius. By providing appropriate coolant to control the machining temperature and lubricate the cutting tool and workpiece surface, machining accuracy can be improved, tool life extended, and surface quality enhanced.

[0003] Currently, in the operation of existing machine tool fluid supply systems, various factors such as fluctuations in the output pressure of the delivery pump during the fluid transportation process can cause the coolant to fail to adequately cool the machining area. This can lead to excessively high local temperatures on the workpiece, causing thermal expansion and affecting machining quality. Therefore, this application provides a constant high pressure intelligent fluid control system for machine tools to meet this requirement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a constant high pressure intelligent fluid control system for machine tools to solve the problem of unstable fluid pressure during the use of existing machine tool fluid supply systems.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] A constant high pressure intelligent fluid control system for machine tools includes: a base plate; a liquid storage tank disposed on the base plate; a delivery pump disposed on the base plate, the output end of the delivery pump being connected to the liquid storage tank; a connecting pipe disposed above the base plate; a delivery pipe having one end connected to the delivery end of the delivery pump and the other end connected to the connecting pipe; a main voltage stabilizer disposed on the delivery pipe and located at the center of the delivery pipe; and two auxiliary voltage stabilizers disposed on the delivery pipe, one near the delivery pump and the other near the connecting pipe; the main voltage stabilizer and the two auxiliary voltage stabilizers are identical.

[0007] It also includes: a variable frequency speed controller, which is installed on the delivery pump and electrically connected to the delivery pump; and a pressure sensor, which is installed on the delivery pipe.

[0008] It also includes: a support member, which is disposed on the base plate and connected to the connecting pipe for supporting the connecting pipe; and a nozzle, which is detachably disposed on the connecting pipe.

[0009] The main pressure stabilizing component includes: a pressure stabilizing tank, which is disposed above the base plate; and a channel pipe, one end of which is connected to the pressure stabilizing tank and the other end of which is connected to the conveying pipe.

[0010] It also includes: a control valve, which is installed on the channel pipe.

[0011] It also includes: two membranes disposed inside the pressure stabilizing tank, arranged vertically; an inlet cavity is formed between the two membranes; and gas is filled between the membranes and the inner cavity of the pressure stabilizing tank.

[0012] It also includes: a cover, which is detachably mounted on the top of the liquid storage tank; and a first filter screen, which is detachably mounted on the cover.

[0013] It also includes: a second filter screen, which is detachably mounted on the cover and located inside the first filter screen; the pore size of the first filter screen is smaller than that of the second filter screen.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects.

[0015] In the above scheme, by setting a main pressure stabilizer and two auxiliary pressure stabilizers, the liquid pressure during the transportation process can be adjusted and stabilized in multiple directions. When the liquid pressure changes during transportation due to factors such as fluctuations in the output pressure of the delivery pump or changes in pipeline resistance, the auxiliary pressure stabilizer near the delivery pump can initially buffer the sudden pressure change, the main pressure stabilizer performs the main pressure adjustment in the center position, and the auxiliary pressure stabilizer near the connecting pipe can further stabilize the pressure, ensuring that the liquid delivered to the nozzle can maintain a relatively stable high pressure state, thereby effectively avoiding the adverse effects of pressure fluctuations on the processing quality.

[0016] By installing a pressure sensor, the pressure of the liquid in the delivery pipe can be monitored in real time. When pressure fluctuations occur, the speed of the delivery pump can be adjusted by a frequency converter to maintain the stability of the liquid pressure in the delivery pipe and ensure that the liquid pressure is always within a suitable range during the processing.

[0024] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0025] The present invention provides a machine tool constant high pressure intelligent fluid control system with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art can also use other alternative methods to implement the system; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0026] like Figure 1 - Figure 5 As shown, an embodiment of this utility model provides a machine tool constant high pressure intelligent fluid control system, including: a base plate 1; a liquid storage tank 2, disposed on the base plate 1; a delivery pump 9, disposed on the base plate 1, with the output end of the delivery pump 9 connected to the liquid storage tank 2; a connecting pipe 6, disposed above the base plate 1; a delivery pipe 4, one end connected to the delivery end of the delivery pump 9, and the other end connected to the connecting pipe 6; a main pressure stabilizer 11, disposed on the delivery pipe 4 and located at the center of the delivery pipe 4; and two auxiliary pressure stabilizers 10, respectively disposed on the delivery pipe 4, one near the delivery pump 9 and the other near the connecting pipe 6; the main pressure stabilizer 11 and the two auxiliary pressure stabilizers 10 are identical.

[0027] The base plate 1 is equipped with casters at all four corners to enhance the mobility of the device and meet the needs of various scenarios. In addition, the casters are made of metal, which is intended to increase the pressure brought by the base plate 1 while reducing the wear and tear on the casters and reducing maintenance costs.

[0028] It also includes: a variable frequency drive 5, which is installed on and electrically connected to the delivery pump 9; and a pressure sensor 12, which is installed on the delivery pipe 4. By installing the variable frequency drive 5 and electrically connecting it to the pressure sensor 12, when the pressure sensor 12 detects that the pressure is too high, the variable frequency drive 5 will reduce the speed of the delivery pump 9, reduce the liquid flow rate, and thus reduce the pressure; conversely, when the pressure is too low, the speed of the delivery pump 9 will be increased, the liquid flow rate will be increased, and the pressure will rise again, thereby maintaining the stability of the liquid pressure in the delivery pipe 4.

[0029] It also includes: a support member 8, which is mounted on the base plate 1 and connected to the connecting pipe 6, for supporting the connecting pipe 6; and a nozzle 7, which is detachably mounted on the connecting pipe 6. By setting the support member 8, a cylinder or electric telescopic rod can be used to enable it to lift and lower, thereby adjusting the height of the nozzle 7. At the same time, the delivery pipe 4 uses a flexible hose and is not affected by changes in its height. By setting the nozzle 7, it can be installed with the connecting pipe 6 by quick plugging, and the connection can be made stable by setting magnetic or snap-fit ​​components on the nozzle 7 and the connecting pipe 6.

[0030] The main pressure stabilizer 11 includes: a pressure stabilizing tank 111, disposed above the base plate 1; and a channel pipe 112, one end of which is connected to the pressure stabilizing tank 111, and the other end of which is connected to the delivery pipe 4. The pressure stabilizing tank 111 in the main pressure stabilizer 11 is larger than the main pressure stabilizer 11 in the auxiliary pressure stabilizer 10, which can hold more liquid, thereby enhancing its pressure stabilizing effect and playing a core stabilizing and supporting role.

[0031] It also includes a control valve 113, which is installed on the channel pipe 112. By setting the control valve 113, when the pressure in the delivery pipe 4 is too high, the liquid enters the channel pipe 112 under the action of the pressure difference. When the pressure in the delivery pipe 4 is too low, the liquid is squeezed by the gas 115 in the pressure stabilizing tank 111, causing the liquid to flow into the channel pipe 112.

[0032] It also includes: two membranes 116, arranged vertically within the pressure stabilizing tank 111; an inlet cavity 114 formed between the two membranes 116; and a gas 115 filling the space between the membranes 116 and the inner cavity of the pressure stabilizing tank 111. By setting up the membranes 116, the liquid and gas 115 within the pressure stabilizing tank 111 are separated, serving an isolation function and preventing gas 115 from mixing into the liquid and forming bubbles. Nitrogen gas can be used as the gas 115, as it is chemically stable and does not readily react with other substances. The inlet cavity 114 serves as a temporary storage space after the liquid from the delivery pipe 4 enters the pressure stabilizing tank 111.

[0033] It also includes: a cover 3, which is detachably mounted on the top of the liquid storage tank 2; and a first filter screen 13, which is detachably mounted on the cover 3. The liquid storage tank 2 is provided with an inlet, and the used coolant can be collected and poured into the liquid storage tank 2 through the inlet. The filter screen can filter the recovered coolant, thereby realizing its reuse. The cover 3 can be installed on the liquid storage tank 2 by means of snap-fit, clip, or bolt. When it is necessary to clean or replace the filter screen, the cover 3 can be removed to replace or clean the filter screen.

[0034] It also includes a second filter screen 14, which is detachably mounted on the cover 3 and located inside the first filter screen 13; the pore size of the first filter screen 13 is smaller than that of the second filter screen 14. By setting the first filter screen 13 and the second filter screen 14, a two-stage filtration mechanism is formed. When the liquid enters the storage tank 2, it first passes through the second filter screen 14 to intercept larger impurities, and then passes through the first filter screen 13 to further filter out finer impurities. It can be installed by means of clips, bolts, or snap-fits.

[0035] The technical solution provided by this utility model involves the operation of a delivery pump 9, which draws coolant from the storage tank 2, delivers it through a delivery pipe 4 to a connecting pipe 6, and then from the connecting pipe 6 to a nozzle 7. The nozzle 7 sprays the coolant onto the cutting area. A pressure sensor 12 monitors the pressure of the coolant in the delivery pipe 4 in real time. If the pressure deviates, a frequency converter 5 automatically adjusts the speed of the delivery pump 9 to quickly correct the pressure deviation. When the coolant pressure in the delivery pipe 4 is too high, the coolant flows through the channel pipe 112 into the pressure stabilizing tank 111. The inlet chamber 114 is filled with coolant. As the coolant flows in, the pressure inside the inlet chamber 114 increases. The upper and lower membranes 116 are squeezed to both sides by the coolant, thereby squeezing the surrounding gas 115. The gas 115 is compressed and its volume decreases. When the coolant pressure in the delivery pipe 4 is too low, the coolant in the inlet chamber 114 flows back to the delivery pipe 4 through the channel pipe 112 under the pressure of the gas 115. At this time, the gas 115 expands and pushes the membranes 116 to move towards the middle, squeezing the coolant back into the delivery pipe 4.

[0036] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
