[0004] During the use of this cutting fluid filtering device, first, the iron filings in the cutting fluid are filtered out by the filtering frame in the purification box. The filtered iron filings will accumulate inside the filtering frame. When the iron filings accumulate too much, it is easy to block the filter holes, thereby affecting the flow rate of the liquid and reducing the filtering efficiency. Therefore, a filtering device for the cutting fluid of a double-channel and double-spindle numerical control machine tool is proposed. Content of the Utility Model

Springs are sleeved on the outside of the sliding rods and located at the top and bottom of the slider. First clamping grooves are formed on the left and right sides of the filtering box. The first clamping block is clamped inside the first clamping groove.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , a filter device for cutting fluid of a double-channel and double-spindle numerical control machine tool in this embodiment, includes a first box body 1, a support rod 5 and a second box body 8. The support rod 5 is fixedly connected between the second box body 8 and the first box body 1, and a shaking structure is installed inside the first box body 1.

[0023] The shaking structure includes a sliding rod 10 and a filter box 2. The number of sliding rods 10 is two. Installation grooves are opened on the left and right inner side walls of the first box body 1. The sliding rod 10 is fixedly installed inside the installation grooves. A slider 16 is slidably connected to the outside of the sliding rod 10. A first clamping block 4 is fixedly connected to the side of the slider 16 away from the first box body 1. Springs 21 are sleeved on the outside of the sliding rod 10 at the top and bottom of the slider 16. First clamping grooves 15 are opened on both the left and right sides of the filter box 2. The first clamping block 4 is clamped inside the first clamping groove 15. A filter screen is fixedly embedded at the bottom of the filter box 2. The filter box 2 matches the inner wall of the first box body 1.

[0024] It can be understood that by setting the jitter structure, when the cutting fluid flows into the first box body 1 through the liquid inlet pipe 3, it will be filtered by the filter box 2. The impact force of the water flow will push the filter box 2 downward, so that the slider 16 slides on the slide bar 10 and squeezes the spring 21 to expand and contract, enabling the filter box 2 to jitter up and down, thus preventing the iron filings filtered in the filter box 2 from accumulating together and blocking the filter holes, which affects the liquid flow rate.

[0025] Among them, open the second sealing door 20, remove the filter box 2 from the first box body 1, and separate the first clamping block 4 from the first clamping groove 15 to take out the filter box 2, thus facilitating the cleaning of the filtered iron filings.

[0026] A filter assembly for further filtering impurities in the cutting fluid is installed inside the second box body 8. The filter assembly includes a placement box 13. Activated carbon particles 12 are placed inside the placement box 13. A plurality of liquid outlet holes 11 are opened at the bottom of the placement box 13. Second clamping grooves 18 are opened on both the left and right sides of the placement box 13. Second clamping blocks 17 are fixedly connected to the inner side walls on both the left and right sides of the second box body 8. The second clamping grooves 18 are clamped inside the second clamping blocks 17. A first sealing door 19 is hinged to the front surface of the second box body 8. A drain pipe 9 is fixedly penetrated through the right side of the second box body 8. A flow guide plate is fixedly installed on the inner bottom wall of the second box body 8.

[0027] It should be noted that when it is necessary to replace the activated carbon particles 12, open the first sealing door 19 and remove the placement box 13 from the second box body 8, which is convenient for replacing the activated carbon particles 12.

[0028] In this embodiment, a liquid inlet pipe 3 is fixedly penetrated through the top of the first box body 1. A second sealing door 20 is hinged to the front surface of the first box body 1. A connecting pipe 6 is fixedly penetrated through the bottom of the first box body 1. The bottom of the connecting pipe 6 is fixedly connected to a shunt box 7. A plurality of liquid outlet pipes 14 are fixedly penetrated through the bottom of the shunt box 7. The bottoms of the liquid outlet pipes 14 penetrate through the top of the second box body 8 and extend to the inside.

[0029] It should be noted that by setting the shunt box 7 and the liquid outlet pipes 14, the effect of shunting the liquid is achieved, so that the cutting fluid flows down evenly and is filtered by the activated carbon particles 12 to adsorb the impurities therein.

[0030] The working principle of the above embodiment is as follows: When in use, the cutting fluid flows into the first box body 1 through the liquid inlet pipe 3 and will be filtered by the filter frame 2. The impact force of the water flow will push the filter frame 2 downward, so that the slider 16 slides on the slide bar 10 and compresses the spring 21 to make it expand and contract. Through the elasticity of the spring 21 itself, the filter frame 2 can be jolted up and down, so as to prevent the iron filings filtered in the filter frame 2 from accumulating together and blocking the filter holes, which affects the liquid flow rate. The preliminarily filtered cutting fluid then flows into the shunt box 7 through the connecting pipe 6, is shunted, and then flows into the second box body 8 from multiple liquid outlet pipes 14, and is further filtered and adsorbed by the activated carbon particles 12 in the placement box 13 to remove impurities in the cutting fluid, and then is discharged from the drain pipe 9.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
