[0002] Most of the automotive parts processing requires the use of lathes. During the operation of the lathe, the tool and the parts to be processed will generate a lot of heat, which requires a cooling system to cool them. Currently, most of the tools and parts are cooled by spraying cutting fluid. The cutting fluid will absorb some heat during the circulation process. Since the filtered cutting fluid is not cooled during the circulation system, the cutting fluid will heat up when it is circulated for a long time, and the cooling effect of the cutting fluid is reduced, thereby affecting the use effect of the entire cooling circulation system.

[0014] The present invention has the following advantages: the present invention uses the centrifugal force generated by the rotation of the separating ring and the connecting plate to throw the cutting fluid flowing out from the lower part of the through groove toward the inner wall of the cooling cylinder. The cutting fluid contacts the inner wall of the cooling cylinder and is quickly cooled by the low-temperature cylinder wall of the cooling cylinder, thereby achieving the purpose of rapid cooling. This solves the problem in the prior art that the filtered cutting fluid is not cooled during the circulation system process, the cutting fluid will heat up when circulated for a long time, and the cooling effect of the cutting fluid is reduced.

[0015] The setting of the liquid outlet pipe will cause the cutting fluid to be thrown out in the form of strands. When the cutting fluid contacts the inner wall of the cooling cylinder, the flake-shaped cutting fluid has a large flow rate. Therefore, the flake-shaped cutting fluid will quickly flow downward from the inner wall of the cooling cylinder, while the strand-shaped cutting fluid has a small flow rate and can flow more slowly along the inner wall of the cooling cylinder, thereby increasing the contact time between the cutting fluid and the inner wall of the cooling cylinder and achieving a better cooling effect.

[0016] The present invention transports the cutting fluid upward after the lower part thereof has been initially cooled by the wall of the cooling cylinder through the blades. After the cutting fluid passes over the upper surface of the inner cylinder, it flows downward along the outer wall of the inner cylinder. In this way, after the cutting fluid has been initially cooled by the wall of the cooling cylinder, it is subjected to secondary cooling by the outer wall of the inner cylinder, thereby increasing the cooling speed of the cutting fluid while achieving a better cooling effect.

[0017] The present invention transports the cutting fluid in the upper part downward through the blades, so that in the lower cavity of the cooling cylinder, the upper layer of the cutting fluid can flow downward in the inner cylinder, and then flow out from the lower part of the inner cylinder to the area between the outer cylinder wall of the inner cylinder and the inner wall of the cooling cylinder, and then flow upward along the area between the outer cylinder wall of the inner cylinder and the inner wall of the cooling cylinder to the upper part of the blades, and then be transported downward by the blades. In this way, the upper and lower layers of the cutting fluid in the lower cavity of the cooling cylinder continue to flow and contact with the cooling gas in the cooling cylinder, so that the cutting fluid increases the cooling speed while achieving a better cooling effect.

[0018] The space in the upper cavity of the cooling cylinder gradually increases, while the space in the lower cavity of the cooling cylinder is gradually compressed, so that the gas in the lower cavity of the cooling cylinder is quickly ejected upward through the liquid outlet pipe and the liquid outlet hole, and the upwardly ejected gas flushes the debris on the filter mesh upward, so that it falls on the upper surface of the ring; with the rotation of the connecting plate, the separating ring and the ring, the centrifugal force generated will throw the debris on the upper surface of the ring toward the chip discharge groove and into the sealing ring, and then control the external pump to quickly extract the cutting chips through the chip discharge pipe.

[0019] After the air valve is closed, the solenoid valve provided at the connection between the liquid infusion pipe and the cooling cylinder is closed. Since the air pressure inside the high-pressure liquid spray pipe is in a high-pressure state, while the liquid infusion pipe is in a normal pressure state, the high-pressure gas in the high-pressure liquid spray pipe will be affected by the pressure difference and the diaphragm provided at the connection between the liquid infusion pipe and the high-pressure liquid spray pipe will be flushed open, so that a small amount of cutting fluid in the high-pressure liquid spray pipe will enter the liquid infusion pipe for temporary storage; when cooling is needed again and the air valve is opened, the cutting fluid in the liquid infusion pipe will leak out and be quickly sprayed out from the nozzle of the high-pressure liquid spray pipe. In this way, even if the connection between the air valve and the high-pressure liquid spray pipe is not tight, there will be no leakage of cutting fluid. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. Example 1

[0030] A high-pressure cooling device for automobile parts production, such as Figures 1-8 As shown, it includes a mounting plate 1, a cooling cylinder 2, a screw rod 3, a nut 4 and a power assembly; the mounting plate 1 is bolted to the cooling cylinder 2; the wall of the cooling cylinder 2 is set as a hollow double-layer structure; the cooling cylinder 2 is rotatably connected to the screw rod 3; the screw rod 3 is transmission-connected to the nut 4; the mounting plate 1 is provided with a power assembly, and the power assembly is connected to the screw rod 3;

[0031] It also includes a connecting disk 7, a separating ring 8, a circular ring 11, a telescopic plate 12, a connecting plate 13, a multi-section telescopic rod 14 and a connecting rod 15; the nut 4 is rotatably connected to the connecting disk 7; the connecting disk 7 is fixedly connected to the separating ring 8; the separating ring 8 is provided with a plurality of liquid outlet holes 8a; the separating ring 8 is fixedly connected to the circular ring 11, and the circular ring 11 is slidingly connected to the cooling cylinder 2; the connecting disk 7 is set to a conical structure with a larger bottom and a smaller top, and the inner ring surface of the circular ring 11 is set to a conical structure with a larger bottom and a smaller top, and a through groove is provided between the connecting disk 7 and the circular ring 11; the connecting disk 7 and the circular ring 11 divide the cooling cylinder 2 into two upper and lower cavities; the circular ring 11 is bolted to the telescopic plate 12, and the telescopic plate 12 is adaptively telescopic as the circular ring 11 moves up and down; the telescopic part of the telescopic plate 12 is fixedly connected to the connecting plate 13, and the connecting plate 13 is fixedly connected to the upper part of the screw rod 3 ; At least two multi-section telescopic rods 14 are installed at the inner lower part of the cooling cylinder 2; the telescopic part of each multi-section telescopic rod 14 is fixedly connected to a connecting rod 15, and all the connecting rods 15 are fixedly connected to the lower part of the nut 4. The multi-section telescopic rod 14 will adaptively extend and retract as the nut 4 rises or falls; the connecting plate 13, telescopic plate 12, ring 11, separator ring 8 and connecting disk 7 are driven to rotate by the screw rod 3. At the same time, the nut 4 drives the connecting disk 7 and its connecting parts to move upward, compressing the air in the upper cavity, so that the cutting fluid in the upper cavity is subjected to the pressure of the gas and flows rapidly to the lower cavity through the through groove between the connecting disk 7 and the ring 11, and the centrifugal force generated by the rotation of the separator ring 8 and the connecting disk 7 throws the cutting fluid flowing out from the lower part of the through groove to the inner wall of the cooling cylinder 2, thereby achieving the cooling purpose.

[0032] The power assembly includes a mounting frame 5 and a motor 6; the mounting plate 1 is bolted to the mounting frame 5; the mounting frame 5 is mounted with the motor 6, and the output shaft of the motor 6 is fixedly connected to the screw rod 3.

[0033] It also includes a liquid outlet pipe 9; the connecting plate 7, the separating ring 8 and the circular ring 11 are jointly provided with a plurality of liquid outlet pipes 9 distributed in a circular array, and the number of the liquid outlet pipes 9 matches the liquid outlet hole 8a, and the liquid outlet pipe 9 is connected to the liquid outlet hole 8a. The through groove between the connecting plate 7 and the circular ring 11 will cause the cutting fluid to be thrown out in the form of sheets, and the liquid outlet pipe 9 will cause the cutting fluid to be thrown out in the form of strands, which has better contact with the inner wall of the cooling cylinder 2.

[0034] A filter is provided between the connecting disc 7 and the separating ring 8; the filter filters and intercepts cutting debris in the cutting fluid.

[0035] The scraper 10 is also included; the scraper 10 is fixed to the nut 4, and the lower surface of the scraper 10 is in contact with the filter screen, and the debris on the filter screen is scraped by the scraper 10.

[0036] The cooling process of the cutting fluid of the present invention is as follows:

[0037] A cold air conveying device is installed on the upper and lower parts of the cooling cylinder 2. Cold air is injected into the internal cavity of the cooling cylinder 2 and the hollow double-layer structure of the cooling cylinder 2 through the cold air conveying device, so that the interior of the cooling cylinder 2 and the cylinder wall of the cooling cylinder 2 are kept at a low temperature.

[0038] The initial positions of the nut 4, connecting plate 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 are located in the middle and lower part of the cooling cylinder 2. At this time, the space of the upper cavity of the cooling cylinder 2 is larger than the space of the lower cavity;

[0039] Subsequently, the cutting fluid is injected into the upper cavity of the cooling cylinder 2 through the liquid inlet 2a, so that it is transported to the upper surfaces of the connecting disk 7, the separation ring 8 and the ring 11;

[0040] At the same time, the motor 6 drives the screw 3 to rotate forward, so that the screw 3 drives the connecting plate 13, the telescopic plate 12, the ring 11, the separating ring 8 and the connecting plate 7 to rotate; and the rotation of the screw 3 causes the nut 4 to drive the connecting plate 7, the ring 11 and its connecting parts to move upward, compressing the air in the upper cavity of the cooling cylinder 2, so that the pressure of the upper cavity of the cooling cylinder 2 increases, while the pressure of the lower cavity of the cooling cylinder 2 decreases, so that the cutting fluid in the upper cavity of the cooling cylinder 2 is affected by the air pressure difference, thereby increasing the flow rate of the cutting fluid, and the cutting fluid passes through the outlet in turn. The through groove between the hole 8a, the connecting plate 7 and the ring 11 flows rapidly to the lower cavity, and the cutting fluid flowing out from the lower part of the through groove is thrown to the inner wall of the cooling cylinder 2 by the centrifugal force generated by the rotation of the separating ring 8 and the connecting plate 7. The cutting fluid contacts the inner wall of the cooling cylinder 2 and is quickly cooled by the low-temperature cylinder wall of the cooling cylinder 2, thereby achieving the purpose of rapid cooling. This solves the problem in the prior art that the filtered cutting fluid is not cooled during the circulation system process, the cutting fluid will heat up when circulated for a long time, and the cooling effect of the cutting fluid is reduced.

[0041] Before the cutting fluid enters the fluid outlet 8a, the cutting debris contained in the cutting fluid is intercepted by the filter.

[0042] It should be noted that when the connecting plate 7 and the separating ring 8 rotate, the filter screen will be driven to rotate synchronously, while the nut 4 and the scraper 10 remain unchanged, so that the upper part of the rotating filter screen is continuously scraped by the scraper 10. The scraper 10 can promptly scrape away the cutting debris that is blocked in the mesh of the filter screen to prevent the cutting debris from clogging the mesh of the filter screen.

[0043] It should be noted that the through groove between the connecting plate 7 and the ring 11 will cause the cutting fluid to be thrown out in the form of sheets, and the setting of the liquid outlet pipe 9 will cause the cutting fluid to be thrown out in the form of strands. When the cutting fluid contacts the inner wall of the cooling cylinder 2, the sheet-like cutting fluid has a large flow rate. Therefore, the sheet-like cutting fluid will flow downward from the inner wall of the cooling cylinder 2 quickly, while the strand-like cutting fluid has a small flow rate and can flow more slowly along the inner wall of the cooling cylinder 2, thereby increasing the contact time of the cutting fluid with the inner wall of the cooling cylinder 2, thereby achieving a better cooling effect.

[0044] After completing the cooling work of a batch of cutting fluid, it is necessary to control the nut 4, connecting plate 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 to return to their initial positions. At this time, let the output shaft of the motor 6 drive the screw 3 to reverse, so that the nut 4 drives the connecting plate 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 to move downward and return to their initial positions.

[0045] After the cutting fluid completes the cooling work, the external conveying equipment is controlled to convey the cutting fluid in the lower cavity of the cooling cylinder 2 to the cooling system so as to cool the tool and parts. Example 2

[0046] On the basis of Example 1, Figure 3 As shown, blades 102 are also included; blades 102 are provided at the lower part of the screw rod 3, and the cutting fluid in the lower cavity of the cooling cylinder 2 is stirred by the blades 102.

[0047] The inner lower portion of the cooling cylinder 2 is bolted to the inner cylinder 101 , and a gap exists between the lower surface of the inner cylinder 101 and the inner bottom surface of the cooling cylinder 2 , and the inner wall of the inner cylinder 101 fits the outer side surface of the blade 102 .

[0048] The secondary cooling process of the present invention is as follows:

[0049] Even though the cutting fluid flows downward along the wall of the cooling cylinder 2 and achieves a certain cooling effect, the cooling speed is still too slow;

[0050] When the screw 3 rotates forward, causing the nut 4, connecting disc 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 to move upward, the screw 3 will drive the blade 102 to rotate counterclockwise from a top-down perspective, so that the blade 102 will transport the cutting fluid after its lower part has been initially cooled by the wall of the cooling cylinder 2 upward. After the cutting fluid passes through the upper surface of the inner cylinder 101, it will flow downward along the outer wall of the inner cylinder 101. In this way, after the cutting fluid is initially cooled by the wall of the cooling cylinder 2, it will be cooled for the second time by the outer wall of the inner cylinder 101, so that the cutting fluid can achieve a better cooling effect while increasing the cooling speed.

[0051] When the screw rod 3 is reversed, causing the nut 4, connecting plate 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 to move downward, the screw rod 3 will drive the blade 102 to rotate clockwise from the top to the bottom, so that the blade 102 transports the cutting fluid on its upper part downward, so that in the lower cavity of the cooling cylinder 2, the upper layer of cutting fluid can flow downward in the inner cylinder 101, and then flow out from the lower part of the inner cylinder 101 to the area between the outer cylinder wall of the inner cylinder 101 and the inner wall of the cooling cylinder 2, and then flow upward along the area between the outer cylinder wall of the inner cylinder 101 and the inner wall of the cooling cylinder 2 to the upper part of the blade 102, and then be transported downward by the blade 102. In this way, the upper and lower layers of cutting fluid in the lower cavity of the cooling cylinder 2 continue to flow and come into contact with the cooling gas in the cooling cylinder 2, so that the cutting fluid increases the cooling speed while achieving a better cooling effect. Example 3

[0052] On the basis of Example 2, Figure 2-4 As shown, a sealing ring 201 is also included; the sealing ring 201 is fixedly connected to the inner upper part of the cooling cylinder 2, and the lower part of the sealing ring 201 is rotatably connected to the ring 11; the sealing ring 201 is set as a retractable structure, and the sealing ring 201 will be compressed or stretched as the ring 11 moves up and down, and the joint between the cooling cylinder 2 and the ring 11 and the upper cavity of the cooling cylinder 2 are isolated by the sealing ring 201.

[0053] The middle portion of the upper surface of the connecting disk 7 and the circular ring 11 is configured as a downwardly concave structure, and the cutting fluid is guided through the concave portions of the upper surface of the connecting disk 7 and the circular ring 11 .

[0054] The sealing ring 201 is configured as a hollow structure; the sealing ring 201 is provided with a chip removal groove 201a, and the chip removal groove 201a is communicated with the upper cavity of the cooling cylinder 2; the cooling cylinder 2 is provided with a chip removal pipe 201b, and the chip removal pipe 201b is snap-connected and communicated with the sealing ring 201, and a sealing piece is provided at the connection between the chip removal pipe 201b and the sealing ring 201, and the chip removal pipe 201b is communicated with the outside world. The debris intercepted on the filter screen is thrown toward the chip removal groove 201a with the centrifugal force generated by the rotation of the connecting plate 7, the separating ring 8 and the circular ring 11, and enters the sealing ring 201, and is then extracted by the chip removal pipe 201b.

[0055] The sealing and isolation work of the present invention is specifically as follows:

[0056] First, connect the external pump to the chip discharge pipe 201b. Since the ring 11 and the inner wall of the cooling cylinder 2 are in sliding connection, after a long period of cooling work, the connection between the ring 11 and the wall of the cooling cylinder 2 is bound to be worn, thereby forming a gap. When the cutting fluid enters the upper cavity of the cooling cylinder 2 from the liquid inlet 2a, the cutting fluid and the cutting debris it carries will flow directly downward along the gap to the lower cavity of the cooling cylinder 2, resulting in a large amount of cutting debris in the lower cavity of the cooling cylinder 2. When the cutting fluid in the lower cavity of the cooling cylinder 2 is used again, this part of the debris will have a serious impact on the normal cutting work.

[0057] To this end, the sealing ring 201 is used to isolate the joint between the cooling cylinder 2 and the circular ring 11 and the upper cavity of the cooling cylinder 2 to prevent the cutting fluid and the cutting debris it carries from flowing directly downward along the above-mentioned gap into the lower cavity of the cooling cylinder 2, so that there are a large amount of cutting debris in the lower cavity of the cooling cylinder 2. When the cutting fluid in the lower cavity of the cooling cylinder 2 is used again, this part of the debris will have a serious impact on the normal cutting work.

[0058] In addition, the cutting fluid is guided by the depressions on the upper surface of the connecting plate 7 and the ring 11, so that the cutting fluid entering the upper cavity of the cooling cylinder 2 from the liquid inlet 2a will only enter the inner ring area of ​​the ring 11 and flow downward quickly, preventing the cutting fluid from entering the sealing ring 201 from the chip groove 201a.

[0059] It should be noted that after completing the cooling work of a batch of cutting fluid, during the process of the nut 4, connecting plate 7, separating ring 8, liquid outlet pipe 9, scraper 10 and ring 11 returning to their initial positions, the space in the upper cavity of the cooling cylinder 2 gradually increases, while the space in the lower cavity of the cooling cylinder 2 is gradually compressed, so that the gas in the lower cavity of the cooling cylinder 2 is quickly ejected upward through the liquid outlet pipe 9 and the liquid outlet hole 8a, and the upwardly ejected gas flushes the debris on the mesh of the filter upward, so that it falls on the upper surface of the ring 11;

[0060] As the connecting plate 7, the separating ring 8 and the circular ring 11 rotate, the centrifugal force generated will throw the debris on the upper surface of the circular ring 11 toward the chip discharge groove 201a and into the sealing ring 201; whenever the sealing ring 201 rises to connect with the chip discharge pipe 201b, the external pump is controlled to quickly extract the cutting debris through the chip discharge pipe 201b. Example 4

[0061] On the basis of Example 3, Figure 1-2 and Figure 8 As shown, it also includes an anti-leakage component, which includes a liquid storage cylinder 301, a high-pressure liquid spray pipe 302 and a liquid infusion pipe 303; the mounting plate 1 is bolted to the liquid storage cylinder 301, and the liquid storage cylinder 301 is communicated with the lower cavity of the cooling cylinder 2; the liquid storage cylinder 301 is provided with a retractable high-pressure liquid spray pipe 302; the high-pressure liquid spray pipe 302 is provided with an air valve 302a; the high-pressure liquid spray pipe 302 is provided with and connected to two liquid infusion pipes 303, and the liquid infusion pipe 303 is communicated with the lower cavity of the cooling cylinder 2, and a diaphragm is provided at the connection between the liquid infusion pipe 303 and the high-pressure liquid spray pipe 302; an electromagnetic valve is provided at the connection between the liquid infusion pipe 303 and the cooling cylinder 2.

[0062] The anti-leakage work of the present invention is specifically as follows:

[0063] After the cutting fluid in the lower cavity of the cooling cylinder 2 is cooled, the cutting fluid in the lower cavity of the cooling cylinder 2 is pumped into the liquid storage cylinder 301 by the pump built into the liquid storage cylinder 301 for storage;

[0064] When the tool and parts need to be cooled, the air valve 302a is opened first, and then the cutting fluid is sprayed toward the tool and parts through the high-pressure spray pipe 302 to perform cooling work;

[0065] When cooling stops, the air valve 302a is closed, and a small amount of cutting fluid that has not been sprayed out from the high-pressure liquid spray pipe 302 will remain in the high-pressure liquid spray pipe 302. After a long period of operation, the connection between the air valve 302a and the high-pressure liquid spray pipe 302 will inevitably become loose. Since the high-pressure liquid spray pipe 302 is in a high-pressure state, the high pressure will force the cutting fluid in the high-pressure liquid spray pipe 302 to be squeezed out from the connection between the air valve 302a and the high-pressure liquid spray pipe 302, thereby causing cutting fluid leakage.

[0066] After the air valve 302a is closed, the electromagnetic valve provided at the connection between the liquid delivery pipe 303 and the cooling cylinder 2 is controlled to be closed. Since the internal air pressure of the high-pressure liquid spray pipe 302 is at high pressure, while the liquid delivery pipe 303 is at normal pressure, the high-pressure gas in the high-pressure liquid spray pipe 302 will open the diaphragm provided at the connection between the liquid delivery pipe 303 and the high-pressure liquid spray pipe 302 due to the pressure difference, so that a small amount of cutting fluid in the high-pressure liquid spray pipe 302 will enter the liquid delivery pipe 303 for temporary storage.

[0067] When cooling is required again and the air valve 302a is opened, the cutting fluid in the liquid delivery tube 303 will leak out and be quickly sprayed out from the nozzle of the high-pressure liquid spraying tube 302. In this way, even if the connection between the air valve 302a and the high-pressure liquid spraying tube 302 is not tight, the cutting fluid will not leak.

[0068] When the cutting work is completed, after the air valve 302a is closed, the solenoid valve set at the connection between the control infusion pipe 303 and the cooling cylinder 2 is opened, and the cutting fluid remaining in the high-pressure spray pipe 302 will enter the infusion pipe 303 and then enter the cooling cylinder 2 for storage.

[0069] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
