[0033] Working principle:

[0034] Initial definition:

[0035] Before use, the user needs to install a motor at one end of the rotating shaft 42 away from the driving box 41, so that the motor serves as the driving source of the rotating shaft 42, and install the cooling liquid spraying device on the outer surface of the double-head numerical control machine tool body 1.

[0036] As Figures 1 to 6As shown, the user installs the axle U-shaped bolt on the machining table 3 by operating the machining table 3, then turns on the power supply of the double-head numerical control machine tool body 1 and the power supply of the cooling liquid spraying device, uses the double-head numerical control machine tool body 1 to thread process the double heads of the axle U-shaped bolt, and sprays cooling liquid through the cooling liquid spraying device during the processing, thereby cooling the axle U-shaped bolt during the processing of the double heads of the axle U-shaped bolt. At this time, the cooling liquid and the debris generated during the processing of the axle U-shaped bolt are mixed together, then introduced into the inside of the workbench 2, and guided to the inside of the introduction pipe 49 through the inclined inner wall in the inside of the workbench 2. The mixture is introduced into the inside of the treatment box 48 from the inside of the introduction pipe 49, so that the mixture is solid-liquid separated by the treatment box 411 and the separation frame 46 in the inside of the treatment box 48, thereby completing the separation and treatment of the cooling liquid during the synchronous processing of the double threads of the U-shaped bolt, thereby avoiding that the debris is soaked in the cooling liquid for a long time, thereby ensuring the performance and stability of the secondary use of the cooling liquid, and by setting the hole diameter of the treatment hole one on the treatment box 411 to be smaller than the hole diameter of the treatment hole two, and the hole diameter of the separation hole is the same as the hole diameter of the treatment hole one, the debris is effectively collected into the inside of the treatment box 411, thereby facilitating the user to collect the debris, thereby speeding up the processing speed of the user to the cooling liquid. The treated cooling liquid is guided out of the inside of the treatment box 48 through the export pipe 410.

[0037] When the user needs to replace the treatment box 411 or the user finds that the flow of the cooling liquid guided out of the export pipe 410 is small, the user needs to turn on the power supply of the motor, and the motor starts to work. The output shaft of the motor drives the rotating shaft 42 to rotate counterclockwise. The rotating shaft 42 drives the transmission gear 43 to rotate counterclockwise when rotating counterclockwise. Since the transmission rack 44 is engaged with the transmission gear 43, the transmission gear 43 drives the two transmission racks 44 to move oppositely when rotating counterclockwise. The two transmission racks 44 drive the two transmission frames 45 to move oppositely when moving oppositely. The two transmission frames 45 drive the two separation frames 46 to move oppositely when moving oppositely. The two separation frames 46 drive the two treatment boxes 411 to move oppositely when moving oppositely, thereby completing the replacement of the two treatment boxes 411, thereby avoiding stopping the separation of the cooling liquid during the replacement of the treatment box 411, thereby improving the separation efficiency of the cooling liquid, and automatically moving the treatment box 411 that has collected the debris out of the inside of the treatment box 48 during the replacement process, which is beneficial to cleaning the debris in time, preventing the performance of the cooling liquid from being reduced, reducing the waste of resources caused by the failure of the cooling liquid, and thereby reducing the probability of waste liquid.

[0038] After one of the processing boxes 411 is removed from the processing container 48, the user manually moves the processing box 411 away from the separator 46. As the processing box 411 moves away from the separator 46, the insertion block 412 moves away from the separator 46. As the insertion block 412 moves away from the separator 46, the positioning block 413 moves away from the separator 46. As the positioning block 413 moves away from the separator 46, it is squeezed by the inner wall of the separator 46, causing the positioning block 413 to be squeezed into the control groove on the insertion block 412. When the positioning block 413 is squeezed into the control groove, it presses the elastic column 414, causing the elastic column 414 to deform. When the insertion block 412 is completely removed from the separator 46, the positioning block 413 pops out by the rebound force of the elastic column 414, which makes it easy for the user to disassemble and install the processing box 411. When the user needs to reinstall the processing box 411, he only needs to repeat the above steps in reverse direction, but the principle is the same.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
