Description

Technical Field

[0001] This invention relates to the field of vertical machining center technology, specifically to a dual-coolant circulation purification device for vertical machining centers. Background Technology

[0002] A vertical machining center is a machining center in which the spindle axis is set perpendicular to the worktable. It is one of the common intelligent manufacturing equipment and is used to process helical parts. During the machining process of parts in a vertical machining center, coolant is required to ensure that the machining head does not overheat and affect the machining quality. The coolant in the vertical machining center has the functions of continuously removing machining heat, optimizing lubrication and cleaning chips, while also ensuring machining accuracy, extending tool life and equipment stability.

[0003] In the operation of traditional machine tools, the main function of coolant is to cool the cutting head and lubricate the contact surface between the cutting head and the product. Therefore, the lubricant carries a lot of heat when it is circulated. In order to ensure that the lubricant can be continuously circulated and to avoid excessive waste, while ensuring the normal machining quality of the vertical machining center, the high-temperature lubricant must be cooled, filtered and purified before reuse. However, traditional lubricant cooling systems not only have poor cooling effect, but also cannot effectively guarantee the quality of filtration and purification. They often require frequent shutdowns for cleaning due to excessive impurities accumulated in the filter structure. This defect seriously reduces the performance of the vertical machining center and also affects the overall efficiency when multiple components are processed together.

[0004] To address the aforementioned issues, we propose a dual-coolant circulation purification device for vertical machining centers. Summary of the Invention

[0039] The purification and cooling component 11 includes a partition vertical plate 1101 fixedly installed on the inner wall of the purification chamber 9. A cooling port 1102 is provided on the bottom surface of the supporting base shell 2 below the partition vertical plate 1101. A cooling structure 14 is provided on the upper side of the inner wall of the cooling port 1102. The cooling structure 14 includes a sealing aluminum plate 1401, and the surface of the sealing aluminum plate 1401 is fixedly connected to the upper side of the inner wall of the cooling port 1102. Several S-shaped heat dissipation aluminum fins 1402 are fixedly installed on the top surface of the sealing aluminum plate 1401. The top surface of the aluminum sheet 1402 is fixedly connected to the bottom surface of the partition vertical plate 1101. Several semiconductor cooling chips 1403 are fixedly installed on the bottom surface of the sealing aluminum plate 1401. The surface of the partition vertical plate 1101 and the side of the inner wall of the purification chamber 9 near the partition inclined plate 5 are filled with filter cotton for filtration. The input end of the liquid pump 10 extends through to the bottom of the inner wall of the purification chamber 9, while the output end of the liquid pump 10 is connected to the surface of the processing machine body 1, and the input end of the liquid pump 10 is located below the left side of the partition vertical plate 1101.

[0040] The working principle of the above embodiments is as follows:

[0041] When the device is in use, the processing body 1 can function as a vertical machining center as a whole, and the product fixture 4 ensures its normal use. This application highlights the innovative structure and does not elaborate on existing mature technologies, such as the processing body 1 and the product fixture 4.

[0042] Before processing, lubricating fluid is added to the purification chamber 9. The purification chamber 9 of this application has the function of adding fluid, which can ensure the initial use effect of lubrication. Before processing, the lubricating fluid in the purification chamber 9 needs to be delivered to the processing head position of the processing machine body 1 by the liquid pump 10, so that the lubricating fluid is introduced to the processing head position of the processing machine body 1 to ensure basic use function. When the processing machine body 1 is processing, the generated debris and lubricating fluid will first be guided by the flow platform 3. The first conical partition bar 302 of the flow platform 3 can ensure that when the liquid flows in the V-shaped inclined groove 301, large debris particles will be separated and intercepted by the first conical partition bar 302, ensuring the initial debris filtration effect. The lubricating fluid will then enter the conical drop cylinder 7 through the drop port 6. The lubricating fluid in the conical drop cylinder 7 will then enter the filter screen cylinder 801.

[0043] The filter cylinder 801 rotates under the output force of the output motor 804, in conjunction with the transmission of the second transmission gear 805 and the first transmission gear 803. This causes the lubricating fluid to undergo centrifugal filtration within the filter cylinder 801 and initial cooling through the force of the ejection. The filtered lubricating fluid then flows into the purification chamber 9 through the liquid inlet 12, guided by the inclined plate 5. There, it undergoes further filtration by the filter cotton. The filtered liquid flows below the vertical partition plate 1101. Because the liquid pump 10 has a pumping effect, it ensures the smooth flow of liquid within the purification chamber 9. When the purified liquid passes under the vertical partition plate 1101, it comes into contact with the S-shaped heat sink 1402 and is cooled again by the semiconductor cooling chip 1403, thus ensuring a dual cooling effect. Finally, the liquid is pumped out by the liquid pump 10 for recycling.

[0044] Furthermore, under the output of the output motor 804, and in conjunction with the transmission of the first conversion gear 806 and the second conversion gear 807, the rotation effect of the fixed vertical column 808 can be guaranteed. The rotation of the fixed vertical column 808 can drive the gap gear 1312 to rotate. When the teeth of the gap gear 1312 mesh with the starting gear 1309, the starting gear 1309 will drive the suction cylinder 1301 to rotate. In this way, the dust suction scraper 1308 on the suction cylinder 1301 will rotate around the inner wall of the filter cylinder 801. And when the starting gear 1309 rotates, it will drive the arc-shaped extrusion plate 1310 to press the self-reset button switch 1311, thereby ensuring the starting and suction effect of the waterproof suction fan 1305. In this way, the dust suction scraper 1308 can process the dust adhering to the filter cylinder 801. The filter cylinder 801 adsorbs impurities from its inner wall, ensuring its continued effectiveness. The gear 1312 drives the starting gear 1309 at a fixed rotation angle, ensuring the arc-shaped extrusion plate 1310 always stops at the same position on one side of the self-reset button switch 1311. Since the self-reset button switches 1311 are equidistantly arranged around the suction cylinder 1301, the device can adsorb and collect impurities during the scraping process of the suction scraper 1308, ensuring the quality of the filtered lubricating fluid impurities. Furthermore, the circulating cooling and purification device is an auxiliary device for better operation of the vertical machining center, and is also a part, component, or accessory of the machine tool.

[0045] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
