[0024] The second filter frame 11 is located directly below the first filter frame 10 , and the diameter of the filter holes of the second filter frame 11 is smaller than the diameter of the filter holes of the first filter frame 10 .

[0025] A liquid injection port 8 is provided on the top outer wall of the storage tank 2 for injecting new cutting fluid into the collection box 1 .

[0026] The disassembly and assembly mechanism includes a limiting cylinder 14 fixedly connected to the outer wall of one side of the collecting box 1, a movable block 15 is slidably connected to the inner wall of the limiting cylinder 14, and a clamping block 16 is fixedly connected to the outer wall of the movable block 15 facing the collecting box 1.

[0027] The disassembly and assembly mechanism also includes a pull rod 17 fixedly connected to the outer wall of the movable block 15 away from the collecting box 1. One end of the pull rod 17 away from the movable block 15 passes through the limiting cylinder 14. A spring 18 is installed on the outer wall of the pull rod 17 located inside the limiting cylinder 14.

[0028] The recovery pipe 3 is used to connect the outlet of the machine tool cutting fluid, and the discharge pipe 4 is used to connect the inlet of the machine tool cutting fluid.

[0029] The implementation principle of a mechanical cutting fluid maintenance and fluid replacement device in the embodiment of the present application is as follows: in actual application, the collection box 1 is used to collect the cutting fluid in the process of using the machine tool, and the collection box 1 is provided with a liquid inlet and a liquid outlet, the liquid inlet is connected to the machine tool cutting fluid outlet through a recovery pipe 3, and the liquid outlet is connected to the storage tank 2 through a liquid discharge pump 6 and a connecting pipe 5;

[0030] When the old cutting fluid in the machine tool is introduced into the collection box 1 through the recovery pipe 3, it will be filtered by the filter assembly to remove impurities. The filter assembly includes a first filter frame 10 and a second filter frame 11. The first filter frame 10 is used to remove larger particles of impurities, and the second filter frame 11 is used to remove smaller particles of impurities. The filtered cutting fluid is pumped into the connecting pipe 5 through the drainage pump 6 and introduced into the storage tank 2 through the connecting pipe 5;

[0031] When the filter assembly is clogged after a long period of filtration, the pull rod 17 is pulled outward through the disassembly mechanism, and the pull rod 17 drives the movable block 15 to slide outward in the limiting cylinder 14, and then the movable block 15 drives the clamping block 16 to disengage from the inside of the clamping slot 13 (such as Figure 4 When the filter presses the filter element 10 and the filter presses the filter element 11, the filter presses the filter element 12 and the filter presses the filter element 13. When the filter presses the filter element 10 and the filter presses the filter element 13, the filter presses the filter element 13 and the filter presses the filter element 13. When the filter presses the filter element 10 and the filter presses the filter element 13, the filter presses the filter element 13 and the filter presses the filter element 13. When the filter presses the filter element 10 and the filter presses the filter element 13, the filter presses the filter element 13 and the filter presses the filter element 13.

[0032] When the filtered cutting fluid enters the storage tank 2, the storage tank 2 is used to store the filtered cutting fluid. The storage tank 2 is provided with a liquid inlet and a liquid outlet. The liquid inlet is connected to the collection box 1 through a connecting pipe 5, and the liquid outlet is connected to the cutting fluid inlet of the machine tool through a cutting fluid pump 7 and a drain pipe 4. The storage tank 2 is also provided with a liquid level sensor 9 for real-time monitoring of the cutting fluid level. When the liquid level is lower than the set value, the control system will automatically start the liquid replacement program. It is worth noting that new cutting fluid can be added to the storage tank 2 through the injection port 8;

[0033] When the liquid replacement program is started, the operation of the entire device is controlled by the control module 12. The control module 12 receives the signal of the liquid level sensor 9. When the liquid level is lower than the set value, the control module 12 will start the cutting fluid pump 7 to pump the cutting fluid in the storage tank 2 into the machine tool, and start the drainage pump 6 at the same time to pump the old cutting fluid in the machine tool into the collection box 1 through the recovery pipe 3, and filter it through the filter component. When the liquid level reaches the set value, the control module 12 will stop the operation of the drainage pump 6 and the cutting fluid pump 7 to complete the liquid replacement process. The liquid replacement process does not require manual intervention, avoiding safety hazards in the manual operation process, such as splashing and leakage of cutting fluid, etc., and has high safety.
