Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. When CNC machine tools process parts, the high-speed rotation of the cutting tool generates a large amount of heat due to friction with the workpiece. Therefore, a cooling system is needed to cool the cutting tool and workpiece surface. Existing cooling systems can only filter out larger debris in the coolant, which still contains fine impurities. Using coolant containing impurities to cool the cutting tool and workpiece surface can affect the machining accuracy, and prolonged use can even damage the cutting tool.

[0003] For example, patent application number 201922375339.0 discloses a CNC machine tool cooling device. This utility model discloses a CNC machine tool cooling device, including a machine tool. The device is characterized by having a box one on the top of the machine tool, a filter screen fixed at the bottom of the box one, a box two inside the machine tool, and a magnetic block one on one side inside the box two. The coolant is initially filtered through the filter screen, and then the magnetic block one and magnetic block two adsorb metal debris in the coolant. Finally, the coolant flows through baffle one and baffle two and settles, settling non-metallic debris in the coolant at the bottom of the box three, thus obtaining clean coolant. It has the advantage of good coolant filtration effect. However, when using the settling box to filter the coolant, fine debris remaining inside the coolant will adhere to the inside of the settling box. If it is not cleaned in time, the debris will accumulate inside the settling box, affecting the normal use of the settling box.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a cooling device for CNC machine tools. Utility Model Content

[0022] like Figures 1-3 As shown, a CNC machine tool cooling device includes a CNC machine tool body 1. A heat dissipation spray assembly 101 is installed on the upper surface of the CNC machine tool body 1, and a conveying pipe 102 is provided on the rear surface of the heat dissipation spray assembly 101. A drain pipe 103 is provided on the left side surface of the CNC machine tool body 1, and a sedimentation tank 2 is provided on the lower surface of the drain pipe 103. The advantage of this arrangement is that, through the arrangement of the heat dissipation spray assembly 101, the machine tool cutting tool can be cooled by spraying water from above the CNC machine tool body 1.

[0023] Furthermore, a drive motor 201 is installed in the middle of the upper surface of the sedimentation tank 2, and a drive rod 202 is installed at the output end of the drive motor 201. A connecting sleeve 204 is provided on the outer surface of the drive rod 202, and a support plate 205 is provided on the outer surface of the connecting sleeve 204. The advantage of this arrangement is that the scraper 206 can be supported by the support plate 205, ensuring the stability of the scraper 206 in use.

[0024] Furthermore, a scraper 206 is provided at the end of the support plate 205, and the scraper 206 is connected to the inner surface of the settling tank 2 by friction. The advantage of this setting is that, by setting the scraper 206, the debris and residue remaining on the inner surface of the settling tank 2 can be scraped off by periodically rubbing against it, so as to avoid the debris residue affecting the sedimentation of the coolant, reduce damage to the settling tank 2, and improve its service life.

[0025] Furthermore, a connecting plate 203 is provided on the lower surface of the drive rod 202, and the connecting plate 203 is fixedly connected to the inner surface of the sedimentation tank 2. The advantage of this arrangement is that the drive rod 202 can be supported by the connecting plate 203.

[0026] Furthermore, a filter 3 is provided on the left side of the upper surface of the settling tank 2, and a water pump 301 is provided on the rear surface of the filter 3. The end of the delivery pipe 102 is connected to the output end of the water pump 301. The advantage of this arrangement is that the coolant inside the settling tank 2 can be filtered by the filter 3, so as to avoid impurities from causing wear on the cutting tool.

[0027] like Figure 4 As shown, the lower outer surface of the sedimentation tank 2 is provided with a threaded groove 4, and a rotating sleeve 401 is spirally installed on the outer surface of the threaded groove 4. The advantage of this setting is that the sedimentation tank 2 and the placement seat 405 can be fixed together by means of threaded connection through the rotating sleeve 401, so as to avoid loosening and leakage.

[0028] Furthermore, a positioning ring 402 is slidably installed on the lower inner surface of the sedimentation tank 2, and a placement seat 405 is provided on the lower surface of the positioning ring 402. The advantage of this setting is that, through the setting of the positioning ring 402, the sedimentation tank 2 can be connected and installed by sliding positioning, so as to avoid the sedimentation tank 2 from shifting during installation and affecting the normal use of the sedimentation tank 2.

[0029] Furthermore, the outer surface of the placement seat 405 is provided with a threaded groove 406, and the placement seat 405 is fixedly connected to the sedimentation tank 2 by a rotating sleeve 401.

[0030] Furthermore, the outer surface of the positioning ring 402 is provided with an installation groove 403, and a sealing gasket 404 is installed on the inner surface of the installation groove 403. The advantage of this setting is that the sealing ability of the sedimentation tank 2 can be improved by setting the sealing gasket 404, thus preventing coolant leakage.

[0031] Working Principle: When using this CNC machine tool cooling device, firstly, when the CNC machine tool body 1 is in use, the water pump 301 starts to draw coolant from the inside of the settling tank 2. After being filtered by the filter 3, it is sent into the interior of the heat dissipation spray assembly 101 through the delivery pipe 102. The spray nozzles of the heat dissipation spray assembly 101 spray the cutting tool inside the CNC machine tool body 1 to cool it down. The cooled coolant is then filtered through the filter screen below the CNC machine tool body 1 and sent into the settling tank 2 through the drain pipe 103 for settling and recycling. To prevent impurities inside the coolant from adhering to the inner wall of the settling tank 2, cleaning is required. The drive motor 201 drives the drive rod 202 to rotate on the upper surface of the connecting plate 203, thereby causing the scraper 206 mounted on the outer surface of the connecting sleeve 204 to rub and scrape off debris on the inner surface of the sedimentation tank 2, ensuring that the inside of the sedimentation tank 2 is clean. When it is necessary to thoroughly remove the impurities and debris settled inside the placement seat 405, the sleeve 401 can be rotated in reverse to move it upward along the threaded groove 4 to disconnect the placement seat 405 and the sedimentation tank 2. Then, the sedimentation tank 2 can be lifted upward to slide it along the positioning ring 402 to complete the separation. After that, the debris and impurities at the bottom of the placement seat 405 can be cleaned. This is the working principle of the cooling device of this CNC machine tool.
