Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a cooling system for machine tool processing, including a mounting plate 1, a support column 2, a water supply mechanism 3, a control mechanism 4, a spraying mechanism 5 and an adjustment mechanism 6. The support column 2 is installed on the top surface of the mounting plate 1, the water supply mechanism 3 is installed at the upper end of the support column 2, the control mechanism 4 is installed on the surface of the water supply mechanism 3, the spraying mechanism 5 is installed at the front end of the water supply mechanism 3, the adjustment mechanism 6 is installed in the middle of the water supply mechanism 3. The spraying mechanism 5 includes a spraying unit and an adjustment unit. The spraying unit is installed at the front end of the water supply mechanism 3, and the adjustment unit is installed in the middle of the spraying unit.

[0029] The water supply mechanism 3 includes a booster pump 301, a water supply hose 302 and a water supply copper pipe 303. The booster pump 301 is fixedly installed on the top surface of the mounting plate 1, the water supply copper pipe 303 is fixedly installed at the top end of the support column 2, the bottom end of the water supply hose 302 is fixedly installed at the output end of the booster pump 301, and the top end of the water supply hose 302 is fixedly installed at the rear end of the water supply copper pipe 303.

[0030] The control mechanism 4 includes a fixed ring 401, a telescopic rod 402, a magnet 403, and a handle 404. The fixed ring 401 is fixedly installed on the surface of the water supply copper pipe 303. The telescopic rod 402 is slidably installed in the middle of the fixed ring 401. The magnet 403 is fixedly installed at the right end of the telescopic rod 402. The handle 404 is fixedly installed at the left end of the telescopic rod 402.

[0031] The spraying unit includes a connecting pipe 501, a spray head 502, a connecting rod 503, and a fixed disk 504. The connecting pipe 501 is fixedly installed at the front end of the water supply copper pipe 303. The spray head 502 is fixedly installed at the bottom end of the connecting pipe 501. The top end of the connecting rod 503 is fixedly installed on the bottom surface of the spray head 502. The fixed disk 504 is fixedly installed at the bottom end of the connecting rod 503. By installing the spraying unit in the spraying mechanism 5, after the booster pump supplies water through the water supply copper pipe 303 into the middle of the spray head 502, the water flow hits the fixed disk 504 and then can form a downward scattering shape, thus achieving the purpose of increasing the cooling area.

[0032] The adjusting unit includes a positioning ring 505, a first spring 506, a valve core 507, a flat spray ring 509, and a scattering ring 510. The positioning ring 505 is fixedly installed on the inner wall of the spray head 502. The valve core 507 is slidably installed on the inner wall of the spray head 502. The bottom end of the first spring 506 is fixedly installed on the top surface of the positioning ring 505, and the top end of the first spring 506 is fixedly installed on the bottom surface of the valve core 507. A diversion port 508 is opened in the middle of the valve core 507, and a through hole is opened in the center of the valve core 507, so that the water supplied in the middle of the water supply copper pipe 303 can be sprayed out through the bottom end of the spray head 502. By installing the valve core 507 in the spraying mechanism 5, there are three changes in the pressure in the middle of the water supply copper pipe 303. Under the first layer of pressure, the valve core 507 will not move. Under the second layer of pressure, the valve core 507 will squeeze and contract the first spring 506 by half, and then the diversion port 508 will communicate with the scattering ring 510. Under the third layer of pressure, the valve core 507 can completely squeeze and contract the first spring 506. While the diversion channel of the diversion port 508 communicates with the scattering ring 510, the valve core 507 stops blocking the flat spray ring 509, thus achieving the purpose of adjusting the position of the valve core 507 through pressure. The flat spray ring 509 is fixedly installed on the surface of the connecting pipe 501, and the pipeline of the flat spray ring 509 communicates with the inside of the spray head 502. The scattering ring 510 is fixedly installed on the surface of the spray head 502, and the pipeline of the scattering ring 510 communicates with the inside of the spray head 502. By installing the adjusting unit in the spraying mechanism 5, after the pressure inside the water supply copper pipe 303 changes, the valve core 507 can move downward in the spray head 502 to squeeze the first spring 506, so that the first spring 506 communicates with the scattering ring 510, thus achieving different spraying effects.

[0033] The adjusting mechanism 6 includes a hollow retaining ring one 601, a hollow retaining ring two 602, a hollow retaining ring three 603, a stop block one 604, a stop block two 605 and a spring two 607. The hollow retaining ring one 601 is fixedly installed on the inner wall of the water supply copper pipe 303. The hollow retaining ring two 602 is fixedly installed on the inner wall of the water supply copper pipe 303 and is installed on the right side of the hollow retaining ring one 601. The hollow retaining ring three 603 is fixedly installed on the inner wall of the water supply copper pipe 303 and is installed on the right side of the hollow retaining ring two 602. The through holes in the hollow retaining ring one 601, the hollow retaining ring two 602 and the hollow retaining ring three 603 are equal, and the through hole in the middle is larger than the through slot in the middle of the stop block two 605. The stop block one 604 is movably installed in the middle of the hollow retaining ring one 601 and the hollow retaining ring two 602. The stop block two 605 is installed in the middle of the hollow retaining ring two 602 and the hollow retaining ring three 603. Through slots 606 are provided in the middle of both the stop block one 604 and the stop block two 605. Both the stop block one 604 and the stop block two 605 are in two semi-circular shapes. When the two stop block ones 604 or the two stop block twos 605 are butted, they form a complete ring. Spring slots are provided in the middle of both the stop block one 604 and the stop block two 605, and the through slot 606 in the middle of the stop block one 604 is smaller than the through slot 606 in the middle of the stop block two 605. The spring two 607 is fixedly installed in the middle between the stop block one 604 and the inner wall of the water supply copper pipe 303. By installing the control mechanism 4 and the adjusting mechanism 6, the water pressure inside the water supply copper pipe 303 can be adjusted. Furthermore, the valve core 507 can be moved in the middle of the spray head 502, so that the spraying form can be adjusted, achieving the purpose of adjusting the spraying form.

[0034] In the use of the present invention, first, the booster pump 301 is turned on, and water is supplied into the interior of the water supply copper pipe 303 through the water supply hose 302. The water flow flows through the water supply copper pipe 303 to the connecting pipe 501 and the spray head 502, and then the water flow flows to the surface of the fixed disk 504 to form a diffused flow, thereby cooling the numerical control machine tool. Push the handle 404 to make the telescopic rod 402 drive the magnet block 403 to move to the right. When the magnet block 403 passes outside the first stop block 604, the first stop block 604 is attracted outward by the magnet block 403 to open the two first stop blocks 604. At this time, the second spring 607 is compressed. Since the through groove 606 in the middle of the second stop block 605 is larger than the through groove 606 in the middle of the first stop block 604, the water flow through amount increases, increasing the water pressure inside the spray head 502. While the water pressure inside the spray head 502 increases, the valve core 507 moves downward to squeeze and contract the first spring 506 until the diversion port 508 is aligned with the scattering ring 510, and the internal water flow is released, so that the water pressure inside the spray head 502 reaches equilibrium. After the water flow enters the scattering ring 510, the water flow forms an umbrella shape and sprays outward. If the expected cooling effect has not been achieved, the magnet block 403 is continuously pushed to the right through the handle 404 and the telescopic rod 402, so that the magnet block 403 stays outside the second stop block 605. Then, the second stop block 605 and the first stop block 604 are also attracted and opened by the magnet block 403, and the two second stop blocks 605 move outward at the same time, completely opening the middle part. After the second stop block 605 is opened, the water pressure inside the spray head 502 increases. At this time, the discharge capacity of the bottom end of the spray head 502 and the scattering ring 510 can no longer meet the release of the water pressure. At this time, the water flow in the middle of the spray head 502 and the valve core 507 further pushes the valve core 507 downward to compress the first spring 506. At this time, the valve core 507 moves downward, and the branch flow of the diversion port 508 communicates with the scattering ring 510, and the valve core 507 stops blocking the flat spray ring 509. Thus, the bottom of the spray head 502, the scattering ring 510, and the flat spray ring 509 release the water flow at the same time, achieving direct spraying, flat spraying, and scattering simultaneously, thereby meeting the cooling requirements. If it is necessary to restore the spraying state, just pull the handle 404 backward to reset the magnet block 403. Then, the first stop block 604 and the second stop block 605 stop being magnetically bound, and the second spring 607 pushes the first stop block 604 and the second stop block 605 to reset to the middle. During the reset, the water flow is blocked, thereby reducing the water pressure inside the spray head 502. Further, the first spring 506 pushes the valve core 507 to move upward to reset, so that the spraying state can be restored.
