Description

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. When a CNC machine tool is machining a workpiece, the temperature of both the tool and the workpiece will increase. Therefore, a cooling circulation structure is required. The cooling circulation structure can spray coolant onto the tool and the workpiece to achieve cooling. The coolant not only has the effect of cooling, but also has the functions of extending the service life of the tool, improving the machining accuracy of the workpiece, and removing metal chips. The existing cooling circulation structure was found to lack the function of filtering and removing metal shavings from the coolant. This caused metal shavings to enter the circulation pump when it was drawing coolant, which led to pump damage. In addition, the existing cooling circulation structure does not have the function of cooling the coolant. As a result, the temperature of the coolant will increase as it circulates and the cooling effect will become worse. Therefore, improvements are needed.

To achieve the purpose of support, the device adopts the following technical solution: support legs 58 are fixedly connected to the front and rear sides of the housing 3 and the front and rear sides of the storage box 1. The support legs 58 can support the device, and the design of the support legs 58 also allows the device to be installed on a CNC machine tool using bolts.

[0019] The usage process of this invention is as follows: Since the cover plate 8 is connected to the filter box 2 by bolts, the cover plate 8, pipe 2 9, receiving shell 10, three filter plates 14, rotating shaft 11, prism 12, and other components can be removed from the filter box 2. Then, the device is placed on a CNC machine tool, and the cover plate 8 and other components are inserted back into the filter box 2 through the slots on the CNC machine tool surface. When inserting, align the prism 12 with the slot and insert it. Then, use bolts to tighten the cover plate 8 to the filter box 2. Then, move the metal hose 6 to align the nozzle 7 with the processing position of the workpiece. Figure 10 As shown; When the CNC machine tool needs to cool down the workpiece during processing, the switch valve 25 is opened, and then enough coolant is added to the storage tank 1 through the feed pipe 24. Then, the circulation pump 4 is controlled to work through the pipe 5 and the metal hose 6, so that the coolant can be sprayed out from the nozzle 7. This sprays onto the workpiece and the tool, thereby achieving cooling. At the same time, it can also wash away the metal chips generated during processing. The metal chips and coolant will fall into the receiving shell 10, and then enter the filter box 2 through the two pipes 9. Finally, it returns to the storage tank 1 through the two pipes 23. During this time, the circulation pump 4 continues to work, so as to realize the reuse of coolant and achieve circulating cooling. When the coolant enters the filter box 2, it passes through three filter plates 14, each equipped with a filter screen 15. This allows the coolant to filter out metal shavings as it flows through the filter box 2, thus enabling the device to remove metal shavings from the coolant. This prevents metal shavings from entering the circulation pump 4 and causing damage. Furthermore, the mesh size of the three filter screens 15 gradually decreases, ensuring effective filtration of metal shavings. When the coolant is sprayed onto the workpiece and cutting tool, it absorbs heat, causing the coolant temperature to rise. At this point, the cooling element 32 is activated to cool the coolant in the storage tank 1, preventing the coolant temperature from rising further and ensuring effective cooling of the cutting tool and workpiece. While the circulating pump 4 and the cooling plate 32 are working, the motor 26 is controlled to work. The motor 26 drives the reciprocating screw 27 to rotate, which in turn drives the chain 30 to rotate. The chain 30 drives the rotating shaft 20 to rotate, which in turn drives the bevel gear 21 to rotate. The bevel gear 21 drives the bevel gear 22 to rotate, which in turn drives the rotating shaft 11 to rotate. Since the prism 12 is embedded in the groove, the rotation of the rotating shaft 11 can cause the prism 12 to rotate, which in turn causes the rotating shaft 11 and the three cleaning brushes 17 to rotate. This can clean the metal shavings on the filter screen 15, thereby preventing the metal shavings from accumulating in one state for a long time and causing the coolant to not flow. The reciprocating screw 27 rotates, causing the sliding seat 28 and the gear plate 41 to move back and forth continuously. This, in turn, causes the first gear ring 40 and the rotating plate 39 to rotate back and forth continuously, which in turn drives the rotating shaft 33 and the fixed plate 42 to rotate back and forth. The rotating shaft 33 rotates back and forth, causing the first and second levers 34 and 55 to rotate back and forth continuously. This agitates the coolant, ensuring uniform cooling and preventing the coolant temperature in the lower half from being higher than that in the upper half. When the first lever 34 rotates back and forth, the fan blades 36 also rotate back and forth. This rotation of the fan blades 36 agitates the coolant, further agitating it. When the fixed plate 42 rotates back and forth, it also causes the rotating shaft 43, the turntable 44, and the bevel gear 49 to rotate back and forth. Since the bevel gear 49 meshes with the arc-shaped bevel gear ring 50, its rotation... This allows the rotating shaft 43 to rotate back and forth, thereby driving the turntable 44 to rotate back and forth. Since the pull rod 47 can slide with the connecting rod 45 and connecting rod 46 through the bearing connection, when the turntable 44 rotates back and forth, it can continuously pull the moving rod 37 to move left and right back and forth under the action of the pull rod 47 and the spring 48. The moving rod 37 moves left and right back and forth, driving the two connecting rods 56 to move. Since the connecting rod 56 is embedded in the through groove 3, when the connecting rod 56 moves left and right back and forth, it can make the rotating rod 54 swing left and right back and forth about the fixed rod 53 as the rotation axis, thereby driving the second lever 55 to swing left and right back and forth. This can realize that the second lever 55 can rotate back and forth while swinging left and right back and forth, thus increasing the turbulence effect of the coolant. Since the slider 38, which is fixedly connected to the rotating shaft 33, is slidably embedded in the groove on the moving rod 37, it can not only make the moving rod 37 move left and right stably, but also make the moving rod 37 rotate back and forth with the rotating shaft 33.
