[0037] The sprayed cooling liquid falls on the machining table of the machine tool 1 and flows back to the receiving groove 11 formed on the rotating drum 10 from the liquid return port 7, so that the elastic filter plate 14 installed in the receiving groove 11 filters the iron filings and impurities in the cooling liquid. The filtered cooling liquid flows into the liquid return pipe 8 through the liquid receiving port formed on the liquid return pipe 8 and flows back to the liquid collecting tank 5 through the liquid return pipe 8, so as to be reused. After the cooling liquid is filtered by the elastic filter plate 14 for a certain period of time, the driving gear 31 is driven to rotate by the stepping motor 30, so that the driving gear 31 drives the fixed pipe 9 to rotate through the driven gear 27 engaged with the driving gear 31, and the fixed pipe 9 drives the rotating drum 10 to rotate as a whole by 180°, so that the iron filings and impurities filtered out of the elastic filter plate 14 can fall into the receiving tank 28, avoiding the accumulation of iron filings and impurities on the surface of the elastic filter plate 14, which affects the filtering effect of the elastic filter plate 14 on the cooling liquid. At the same time, the elastic filter plate 14 cleaned in the last time is turned over to continue the continuous filtering operation of the cooling liquid at the liquid return port 7. When the rotating drum 10 drives the elastic filter plate 14 used for filtering to rotate, the first guide column 16 installed at the back of the elastic filter plate 14 will slide from the first force storage groove 171 to the first rebound groove 172, so that the first guide column 16 releases the restriction on the elastic filter plate 14, and the elastic filter plate 14 is bounced outwards under the action of its own elasticity, so that the elastic filter plate 14 can bounce off the impurities adhered to its surface.

[0038] In the embodiment, a material bouncing mechanism is installed between the top plate 12 and the end of the rotating drum 10. The material bouncing mechanism includes a spring rod 18 fixedly installed on the outer surface of the rotating drum 10, and the top plate 12 is movably installed at the extension end of the spring rod 18. The outer surface of the top plate 12 is also fixedly installed with a second guide column 21, and a guide disc 22 is installed between the second guide column 21 and the inner wall of the machine tool 1. The outer surface of the guide disc 22 is provided with a second guide groove corresponding to the first guide groove, and the second guide column 21 is slidably installed with the inner wall of the second guide groove. The second guide column 21 is installed with a shaking mechanism on the outer surface, and the second guide groove is composed of a second force storage groove 221, a second rebound groove 222, a second displacement groove 223 and a second reset groove 224.

[0039] At the same time that the first guide column 16 moves to the first rebound groove 172, the second guide column 21 installed on the top plate 12 will also slide from the second force storage groove 221 to the second rebound groove 222, so that the second guide column 21 contacts the limit of the top plate 12, so that the top plate 12 can drive the elastic filter plate 14 to bounce downwards synchronously and quickly under the action of the elasticity of the spring rod 18, so as to increase the outward elasticity of the elastic filter plate 14, so as to better shake off the impurities adhered to the surface of the elastic filter plate 14.

[0040] In the embodiment, the shaking mechanism comprises an eccentric wheel 23 rotatably installed on the outer surface of the second guide column 21, a force storage disc spring 24 fixedly installed between the eccentric wheel 23 and the second guide column 21, one end of the force storage disc spring 24 fixedly installed on the outer surface of the eccentric wheel 23, the other end of the force storage disc spring 24 fixedly installed on the outer surface of the second guide column 21, a transmission assembly installed between the eccentric wheel 23 and the rotating drum 10, a connecting plate 19 fixedly installed on the outer surface of the top plate 12 and penetrating the end of the rotating drum 10, a limiting column 20 fixedly installed on the extension end of the spring rod 18 and penetrating and slidably installed on the outer surface of the connecting plate 19, and the transmission assembly comprises a transmission rack 32 fixedly installed on the end of the rotating drum 10 and a transmission gear 25 sleeved on the outer surface of the second guide column 21 and engaged with the transmission rack 32.

[0041] When the top plate 12 and the second guide column 21 move downward as a whole, the transmission gear 25 rolls on the transmission rack 32, the transmission gear 25 drives the eccentric wheel 23 to rotate through the one-way bearing 26, the force storage disc spring 24 is installed between the eccentric wheel 23 and the second guide column 21, so that the force storage disc spring 24 can store force when the eccentric wheel 23 rotates, after the transmission gear 25 and the transmission rack 32 are separated, the limitation of the eccentric wheel 23 is released, so that the force storage disc spring 24 can release energy to drive the eccentric wheel 23 to rotate, the connecting plate 19 and the limiting column 20 are movably installed between the top plate 12 and the extension end of the spring rod 18, so that the eccentric wheel 23 can drive the elastic filter plate 14 to shake up and down through the second guide column 21 and the top plate 12 when the eccentric wheel 23 rotates, so as to shake off the impurities adhered to the surface of the elastic filter plate 14 more completely, and further improve the cleaning effect on the surface of the elastic filter plate 14.

[0042] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: in use, the metal workpiece subjected to cutting machining is placed on the machining table of the machine tool 1, the workpiece is clamped and fixed by the clamping part, after the workpiece is fixed, the three-axis motion platform 2 drives the electric cutting knife 3 to move, so that the electric cutting knife 3 performs cutting work on the workpiece; at the same time of cutting work, the cooling liquid in the liquid collecting tank 5 is pumped out by the liquid pump 6 to the cooling liquid spray head 4, so that the cooling liquid spray head 4 lubricates and cools the cutting position of the electric cutting knife 3.

[0043] The sprayed cooling liquid falls on the machining table of the machine tool 1 and flows back to the material receiving groove 11 formed in the rotating drum 10 through the liquid return port 7, so that the elastic filter plate 14 installed in the material receiving groove 11 filters the iron filings and impurities in the cooling liquid, the filtered cooling liquid flows into the liquid return pipe 8 through the liquid inlet formed in the liquid return pipe 8, and flows back to the liquid collecting tank 5 through the liquid return pipe 8, so as to be reused.

[0044] After the cooling liquid is filtered by the elastic filter plate 14 for a certain period of time, the driving gear 31 is driven to rotate by the stepping motor 30, the driving gear 31 drives the fixed tube 9 to rotate through the driven gear 27 engaged with the driving gear 31, and the fixed tube 9 drives the whole rotating drum 10 to rotate 180°, so that the iron filings and other impurities filtered out on the elastic filter plate 14 can be poured into the receiving box 28, avoiding the accumulation of iron filings and other impurities on the surface of the elastic filter plate 14, which affects the filtering effect of the elastic filter plate 14 on the cooling liquid; at the same time, the elastic filter plate 14 cleaned in the last time is turned over to the liquid return port 7 to continue the continuous filtering operation of the cooling liquid;

[0045] When the rotating drum 10 drives the elastic filter plate 14 used for filtering to rotate, the first guide column 16 installed on the back of the elastic filter plate 14 will slide from the first force storage groove 171 to the first rebound groove 172, so that the first guide column 16 releases the restriction on the elastic filter plate 14, and the elastic filter plate 14 is bounced outwards under the action of its own elastic force, so that the elastic filter plate 14 can bounce off the impurities adhered to its surface;

[0046] At the same time that the first guide column 16 moves to the first rebound groove 172, the second guide column 21 installed on the top plate 12 will also slide from the second force storage groove 221 to the second rebound groove 222, so that the second guide column 21 contacts the limit of the top plate 12, and the top plate 12 can drive the elastic filter plate 14 to bounce downwards synchronously and quickly under the action of the elastic force of the spring rod 18, so as to increase the elastic force of the elastic filter plate 14 to the outside, so as to better shake off the impurities adhered to the surface of the elastic filter plate 14;

[0047] At the same time that the top plate 12 and the second guide column 21 move downwards as a whole, the transmission gear 25 will roll on the transmission rack 32, so that the transmission gear 25 drives the eccentric wheel 23 to rotate through the one-way bearing 26, and since the force storage disc spring 24 is installed between the eccentric wheel 23 and the second guide column 21, the eccentric wheel 23 can store force for the force storage disc spring 24 when rotating, and after the transmission gear 25 and the transmission rack 32 are separated, the restriction of the eccentric wheel 23 is released, so that the force storage disc spring 24 can release energy to drive the eccentric wheel 23 to rotate, and since the top plate 12 and the extension end of the spring rod 18 are movably installed through the connecting plate 19 and the limiting column 20, the eccentric wheel 23 can drive the elastic filter plate 14 to shake up and down through the second guide column 21 and the top plate 12 when rotating, so as to more thoroughly shake off the impurities adhered to the surface of the elastic filter plate 14, and further improve the cleaning effect on the surface of the elastic filter plate 14;

[0048] When switching the elastic filter plate 14, the first guide column 16 and the second guide column 21 will slide into the first reset groove 174, the first force storage groove 171 and the second reset groove 224, the second force storage groove 221, respectively and sequentially from the first position slot 173 and the second position slot 223, to complete the re-storing effect of the elastic filter plate 14 and the top plate 12.
