During the processing of CNC machine tools, a cooling device is required to cool the workpiece.

[0003] According to the cooling device of CNC machine tools and CNC machine tools disclosed in Chinese patent announcement No. CN212330493U, the patent can filter larger impurities by setting a filter net, and can also adsorb fine metal waste under the action of a magnet. Finally, after filtering through a filter cloth, it can enter the interior of a heat exchanger for heat dissipation, thereby realizing the recycling of cooling water, which is very practical. However, the patent still has certain shortcomings in actual use. Since the magnet is fixed on the inside of the filter tank, when the metal waste on the magnet needs to be processed, it is necessary to operate inside the narrow filter tank.

In this regard, the present application provides a cooling device of CNC machine tools to solve the above problems. Utility Model Content

[0027] It should be noted that a handle 216 is fixedly installed on the top of the magnet plate 209 and the filter cloth body 215, and the handle 216 is used to facilitate the removal of the corresponding structure. The filter cloth body 215 includes a frame and a square rod fixedly connected to the inside of the frame, and the bottom handle 216 is fixed to the top of the square rod.

[0032] In this embodiment, the heat exchange component 500 is a structure used to assist cooling water in dissipating heat so as to achieve a recycling effect.

[0033] like Figure 1 and Figure 2 As shown, the heat exchange component 500 includes a fixed frame 501 fixedly connected to the inner side of the installation groove 3, a heat exchange tube 502 is fixedly installed on the inner side of the fixed frame 501, one end of the heat exchange tube 502 passes through the right side of the fixed frame 501 and is fixedly installed with a water pump 503, the output end of the water pump 503 is fixedly connected to a return pipe 504, a water tank 505 is fixedly connected to the inner side of the installation groove 3, a water outlet pipe 506 is passed through and fixedly connected to the top of the water tank 505, a booster pump 507 is fixedly installed on the outer side of the water outlet pipe 506, the top end of the water outlet pipe 506 passes through the top of the main block 1 and is fixedly installed with a spray head 508, the front side of the main block 1 is hinged with a first box door 509 located on the front side of the installation groove 3 through a hinge, and the front side of the main block 1 is hinged with a second box door 510 located on the front side of the installation groove 3 through a hinge.

[0034] It should be noted that the top end of the heat exchange tube 502 passes through the interior of the main block 1 and is connected to the interior of the filter tank 201. The inner side of the filter tank 201 is inclined toward the side close to the heat exchange tube 502, so that the cooling water inside the filter tank 201 can enter the interior of the heat exchange tube 502. The outer side of the heat exchange tube 502 is fixedly connected with evenly distributed heat dissipation fins, which can play a role in auxiliary heat dissipation. The right end of the return pipe 504 passes through the left side of the water tank 505, so that the water inside the return pipe 504 can flow back to the interior of the water tank 505. The bottom of the water pump 503 is fixedly connected to the bottom of the installation groove 3, so that the water pump 503 can work stably.

[0035] In addition, the back of the water tank 505 is fixedly connected to a main water pipe that runs through the back of the main block 1. Cooling water can be added to the interior of the water tank 505 through the main water pipe. The bottom end of the water outlet pipe 506 extends to the interior of the water tank 505, so that the cooling water inside the water tank 505 can be discharged through the water outlet pipe 506.

[0036] At the same time, the installation groove 3 is located between the back of the first box door 509 and the second box door 510, a door bolt is fixedly installed between the front of the first box door 509 and the front of the main block 1, and a lock is fixedly installed between the front of the second box door 510 and the front of the main block 1, which is convenient for closing or opening. The front of the first box door 509 is provided with heat dissipation holes for the heat from the heat exchange tube 502 to dissipate, and the heat dissipated by the heat exchange tube 502 can flow to the outside through the heat dissipation holes.

[0037] The working principle of the above embodiment is:

[0038] (1) When the CNC machine tool is machining and the workpiece is cooled synchronously, the workpiece is located on the top of the working panel 403 for machining, and the booster pump 507 is started to extract the cooling water in the water tank 505 through the outlet pipe 506 and then spray it out through the spray head 508 to achieve the cooling of the workpiece. After cooling the workpiece, the cooling water will flow into the inside of the working tank 401 and then enter the inside of the filter box 203 for preliminary filtration, so that the larger waste residues remain in the inside of the filter box 203. The filtered cooling water continues to flow downward, and under the action of the two magnet plates 209 arranged in an opposite direction, the small metal waste chips carried in the cooling water can be adsorbed to achieve the effect of secondary filtration. Finally, the third filtration is performed through the filter cloth body 215. The filtered cooling water enters the inside of the heat exchange tube 502 for heat dissipation. Finally, under the action of the pump 503, the cooling water after heat dissipation is transported back to the inside of the water tank 505 through the return pipe 504, completing the recycling of cooling water.

[0039] (2) When it is necessary to process the waste residue, hold the cylindrical rod 204 and move it upward so that the positioning block 206 is disengaged from the inner side of the corresponding positioning groove 207, and the filter box 203 can be moved to the outside world, which is convenient for processing the waste residue inside. Loosen the hand screw 213, hold the corresponding handle 216 and move it upward so that the fixing block 210 moves to the top of the corresponding limiting cavity 212, and continues to move to the side away from the inner wall of the filter tank 201, so that the net fixing block 210 and the limiting block 211 are disengaged from the inner side of the corresponding limiting cavity 212, and the magnet plate 209 can be taken out, which is convenient for processing the metal waste residue adsorbed on the surface. Hold the corresponding handle 216 and move the filter cloth body 215 upward so that the filter cloth body 215 passes through the inner side of the first annular frame 202 and moves to the outside world, so that the filter cloth body 215 can be cleaned, thereby facilitating the efficient processing of the waste residue.

[0040] Compared with the prior art, the cooling device of the CNC machine tool, through the coordinated use of the filter residue assembly 200 inside the main block 1 and the heat exchange assembly 500, can effectively collect the filtered waste chips and conveniently move them to the outside for cleaning treatment, so that the staff does not need to carry out waste residue treatment work in a narrow trough, which is convenient for the efficient waste residue treatment work and saves the staff's time and energy. It is very convenient, thereby further improving the practicability of the cooling device of the CNC machine tool and solving the problem that the cooling device of the existing CNC machine tool is inconvenient to treat the collected metal waste chips.

[0041] The electrical components appearing in the article are all electrically connected to the main controller and the power supply.
