Description

Technical Field

[0001] This application relates to the field of cleaning systems, and in particular to an automatic cutting fluid cleaning system for a numerically controlled machine tool. Background Technique

[0002] During the process of machining workpieces by a numerically controlled machine tool, it is necessary to continuously spray cutting fluid towards the tool and the workpiece to cool the workpiece and the tool, and reduce the damage of the tool and the workpiece caused by excessive cutting temperature.

[0003] After the cutting fluid contacts the rotating tool and the workpiece, it will carry a large amount of metal chips and splash in all directions. Most of them will fall into the liquid tank at the bottom of the machine tool, and at the same time, a considerable part will remain on the surface of the workbench inside the machine tool. Since the main components of the cutting fluid are usually water, mineral oil and other additives, long-term contact with the workbench is likely to cause the workbench to rust, affecting the overall machining accuracy of the machine tool. Therefore, after the numerically controlled machine tool is used, it is usually necessary to promptly clean the cutting fluid remaining on the surface of the workbench. At present, the cleaning of the cutting fluid remaining on the surface of the workbench is usually completed by manually holding an air gun to flush.

[0004] In view of the above related technologies, on the one hand, the method of manually holding an air gun to flush and clean the remaining cutting fluid has low operating efficiency and is relatively inconvenient to operate. On the other hand, during the process of flushing and cleaning with an air gun, the cutting fluid is easily splashed onto the exposed skin of the operator, which is extremely likely to cause skin allergies and other phenomena; therefore, there is room for improvement. Summary of the Invention

[0005] In order to facilitate the cleaning of the cutting fluid remaining on the surface of the workbench inside the machine tool, this application provides an automatic cutting fluid cleaning system for a numerically controlled machine tool.

[0006] An automatic cutting fluid cleaning system for a numerically controlled machine tool provided by this application adopts the following technical solutions:

[0007] An automatic cutting fluid cleaning system for a numerically controlled machine tool includes a machine tool body, a cleaning mechanism and a collection mechanism;

[0008] A discharge groove is formed at the bottom of the machine tool body;

[0009] The cleaning mechanism includes a cleaning air knife and a sliding driving member. The cleaning air knife is located above the workbench of the machine tool body, and the air outlet of the cleaning air knife is vertically downward; the sliding driving member is drivingly connected to the cleaning air knife and is used to drive the cleaning air knife to slide horizontally;

[0010] The collection mechanism includes a liquid tank located on one side of the machine tool body. A filter box is supported corresponding to the discharge chute at the top of the liquid tank. A filtrate plate is arranged at the bottom of the filter box, and a number of filtrate holes are evenly distributed on the filtrate plate. One end of the discharge chute is connected to a discharge pipe, and the discharge pipe extends into the filter box.

[0011] By adopting the above technical solution, after the numerical control machine tool finishes processing, the cleaning air knife is started and driven by the sliding driving part to reciprocate horizontally. The compressed air ejected by the cleaning air knife is used to blow the cutting fluid remaining on the surface of the workbench together with the chips and the like onto the discharge chute located at the bottom of the machine tool body, so as to realize the automatic cleaning of the cutting fluid and chips remaining on the surface of the workbench. After the cutting fluid and chips falling into the discharge chute flow into the filter box through the discharge pipe, the cutting fluid enters the liquid tank through the filtrate holes on the filtrate plate at the bottom of the filter box, and the chips are filtered out on the surface of the filtrate plate, realizing the separation of the cutting fluid and the chips. On the one hand, it is convenient to clean the cutting fluid remaining on the surface of the workbench inside the machine tool body. On the other hand, when manually cleaning, the cutting fluid is easily splashed onto the exposed skin of the human body, resulting in skin allergies and other symptoms.

[0012] Preferably, the discharge chute extends obliquely downward, and the discharge pipe is located at the inclined lower end of the discharge chute.

[0013] By adopting the above technical solution, by making the discharge chute extend obliquely downward, the cutting fluid and chips falling into the discharge chute subsequently can slide down to the discharge pipe by their own gravity and be discharged to the filter box through the discharge pipe, which is beneficial to reducing the accumulation of cutting fluid and chips in the discharge chute.

[0014] Preferably, an auxiliary discharge assembly is further arranged in the inner cavity of the machine tool body. The auxiliary discharge assembly is located at the inclined upper end of the discharge chute. The auxiliary discharge assembly includes an air supply pipe and a number of air blowing nozzles. The air blowing nozzles are communicated with the air supply pipe, and a number of air blowing nozzles extend obliquely downward towards the discharge chute.

[0015] By adopting the above technical solution, through the setting of the auxiliary discharge assembly, compressed gas is subsequently pumped into the air supply pipe and the compressed air is ejected through a number of air blowing nozzles on the air supply pipe. A number of air blowing nozzles are used to continuously blow compressed air into the discharge chute to assist in blowing the chips and cutting fluid that fall and accumulate in the discharge chute to the discharge pipe and be discharged through the discharge pipe, reducing the situation that the flow of the cutting fluid in the discharge chute is affected due to a large amount of chips accumulating in the discharge chute.

[0016] Preferably, a material pushing assembly is provided at the top of the machine tool body corresponding to the filter box. The material pushing assembly includes a material pushing plate and a material pushing driving member. The material pushing plate is located inside the filter box, and the bottom of the material pushing plate abuts against the filtrate plate. The material pushing driving member is drivingly connected to the material pushing plate and is used to drive the material pushing plate to slide in a direction close to or away from the machine tool body.

[0017] By adopting the above technical solution, through the arrangement of the material pushing assembly, the material pushing driving member is subsequently used to drive the material pushing plate to slide in a direction away from the machine tool body at regular intervals. The material pushing plate is used to push the chips accumulated at the bottom of the discharge pipe to one end of the filter box away from the machine tool body, reducing the concentration of chips discharged from the discharge pipe at the bottom of the discharge pipe, resulting in the blockage of the filtrate holes on the filtrate plate and affecting the normal passage of the cutting fluid through the filtrate plate. This is beneficial to the smooth passage of the cutting fluid through the filtrate holes into the liquid tank.

[0018] Preferably, a drying assembly is further provided in the filter box. The drying assembly is located at one end of the filter box away from the machine tool body. The drying assembly includes a plurality of drying fans. The drying fans are arranged at the top opening of the filter box, and the drying fans are arranged facing the filter box.

[0019] By adopting the above technical solution, the drying fans are used to continuously blow air towards the chips accumulated at one end of the filter box away from the machine tool body, so as to blow the cutting fluid remaining on the surface of the chips away from the chips, which is beneficial to the better separation of the cutting fluid from the chips.

[0020] Preferably, a baffle plate is bent and connected to the top of the material pushing plate. One end of the baffle plate away from the discharge pipe extends to the bottom of the machine tool body. The baffle plate is arranged in contact with the bottom of the discharge pipe.

[0021] By adopting the above technical solution, through the arrangement of the baffle plate, during the process of the material pushing driving member driving the material pushing plate to slide in a direction away from the machine tool body subsequently, the filtrate plate can be temporarily blocked and covered by the baffle plate located at the top of the material pushing plate to prevent the chips discharged from the discharge pipe from directly falling onto the filtrate plate at this time. This avoids the situation that during the process of the material pushing driving member driving the material pushing plate to slide in a direction close to the machine tool body and reset, the material pushing plate pushes the chips on the filter plate to one end of the filter box close to the machine tool body. This is beneficial to the material pushing assembly to centrally push the chips to one end of the filter box away from the machine tool body, so that the drying fan at the drying assembly can blow the cutting fluid remaining on the chips away from the chips. By making the baffle plate abut against the top of the discharge pipe, during the process of the material pushing driving member driving the material pushing plate to slide in a direction close to the machine tool body and reset, the chips and cutting fluid falling onto the baffle plate can be pushed onto the filtrate plate in cooperation with the discharge pipe, restricting the chips and cutting fluid from remaining on the baffle plate and being driven to the bottom of the machine tool.

[0022] Preferably, a discharge air knife is further arranged at the top of the inner cavity of the discharge pipe, and the discharge air knife extends obliquely downward towards the pipe orifice at the end of the discharge pipe away from the discharge groove.

[0023] By adopting the above technical solution, through the arrangement of the discharge air knife, subsequently, compressed air is continuously blown into the discharge pipe through the discharge air knife to assist the cutting fluid flowing through the discharge pipe to accelerate the discharge of the cutting fluid out of the discharge pipe. At the same time, it is beneficial to reduce the chips on the baffle entering and accumulating at the pipe orifice of the discharge pipe when the subsequent pushing driving part drives the push plate to drive the baffle to slide and reset towards the direction close to the machine tool body.

[0024] Preferably, an installation opening is formed at the top of the liquid tank corresponding to the filter box, and an annular support plate is installed at the installation opening, and the bottom of the filter box is lapped on the annular support plate.

[0025] By adopting the above technical solution, by lapping the bottom of the filter box on the annular support plate, while the filter box is stably supported above the liquid tank, when cleaning the chips filtered in the filter box subsequently, the filter box can be removed from the liquid tank, so as to facilitate the cleaning of the chips filtered in the filter box.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When cleaning the residual cutting fluid on the workbench inside the machine tool body, the cleaning air knife is driven by the sliding driving part of the cleaning mechanism to reciprocate horizontally, and the compressed air blown out by the cleaning air knife is used to blow the residual cutting fluid and chips on the surface of the workbench into the discharge groove, and then discharged into the filter box through the discharge pipe at the end of the discharge groove. The cutting fluid entering the filter box enters the liquid tank through the filter holes on the filter plate, and the chips are filtered out on the filter plate, realizing the automatic cleaning of the residual cutting fluid on the workbench inside the machine tool and the effective separation of the cutting fluid and chips at the same time.

[0028] 2. By arranging the auxiliary discharge assembly at the inclined upper end of the discharge groove, subsequently, the air supply pipe of the auxiliary discharge assembly cooperates with a plurality of air blowing nozzles to continuously blow compressed air towards the discharge groove, so as to accelerate the discharge of the cutting fluid and chips in the discharge groove out of the discharge pipe to the outside of the discharge groove, and reduce the situation that chips accumulate concentratedly in the discharge groove and affect the normal flow of the cutting fluid.

[0029] 3. By arranging a chip pushing component at the bottom of the machine tool and arranging a drying component at one end of the filter box away from the machine tool body, the chip pushing driving part can be used to drive the chip pushing plate to move in the direction away from the machine tool body regularly, so as to use the chip pushing plate to push the chips accumulated at the bottom of the discharge pipe to one end of the filter box away from the machine tool body, reducing the situation that the normal flow of the cutting fluid is affected due to a large amount of chips accumulated at the bottom of the discharge pipe; at the same time, after the chips are pushed to one end of the filter box away from the machine tool body by the chip pushing plate, the drying component can blow air on them continuously, so that the cutting fluid remaining on the chips can be separated from the chips and fall into the liquid tank, which is beneficial to further realizing the effective separation of the cutting fluid and the chips.

[0038] The following is a further detailed description of the present application in conjunction with the attached Figures 1-6 drawings.

[0039] An embodiment of the present application discloses an automatic cleaning system for cutting fluid of a numerical control machine tool. Refer to Figure 1 and Figure 2 , which includes a machine tool body 1, a cleaning mechanism 2, and a collection mechanism 3; two discharge grooves 11 are formed at the bottom of the machine tool body 1; the cleaning mechanism 2 is located inside the machine tool body 1; the cleaning mechanism 2 includes a cleaning air knife 21 and a sliding driving member; the cleaning air knife 21 is communicated with a gas source, the cleaning air knife 21 is located above the workbench 10 and the air outlet of the cleaning air knife 21 is vertically downward; the collection mechanism 3 includes a liquid tank 31; two filter boxes 32 are supported above the liquid tank 31 corresponding to the two discharge grooves 11; one end of each discharge groove 11 is communicated with a discharge pipe 111, and the end of the discharge pipe 111 away from the discharge groove 11 extends into the corresponding filter box 32 and is located at one end of the corresponding filter box 32 close to the machine tool body 1; the bottom of the filter box 32 is open, and a filtrate plate 321 for filtering chips is covered at the open bottom of the filter box 32, and a number of filtrate holes are evenly opened on the filtrate plate 321.

[0040] After the machine tool body 1 is used up, the sliding driving member is used to drive the cleaning air knife 21 to reciprocate horizontally, and the compressed air flow blown by the cleaning air knife 21 is used to blow the cutting fluid and chips remaining on the surface of the workbench 10 into the discharge groove 11, so as to realize the automatic cleaning of the cutting fluid and chips remaining on the workbench 10 of the machine tool body 1; the cutting fluid and part of the chips falling into the discharge groove 11 are discharged into the filter box 32 through the discharge pipe 111, the chips wrapped in the cutting fluid are filtered by the filtrate plate 321, and the remaining cutting fluid flows into the liquid tank 31 through the filtrate holes on the filtrate plate 321, so as to realize the effective separation of the cutting fluid and chips.

[0041] Both of the two discharge grooves 11 extend obliquely downward from the direction away from the liquid tank 31 towards the direction close to the liquid tank 31, and the discharge pipes 111 are all located at the inclined lower ends of the corresponding discharge grooves 11. Through the above settings, it is convenient for the cutting fluid and chips falling into the discharge groove 11 subsequently to slide to the inclined lower ends of the discharge groove 11 by their own gravity and be discharged through the discharge pipes 111.

[0042] Refer to Figure 1 and Figure 3, there are two auxiliary chip discharging components 12 arranged in the inner cavity of the machine tool body 1 corresponding to two chip discharging grooves 11; the auxiliary chip discharging components 12 are located at the inclined upper ends of the corresponding chip discharging grooves 11; the auxiliary chip discharging components 12 include an air supply pipe 121, and the air supply pipe 121 is installed on the inner wall of the machine tool body 1 through a bracket; a plurality of air blowing nozzles 122 are evenly installed along the extending direction of the air supply pipe 121 and the air blowing nozzles 122 are all arranged obliquely downward towards the corresponding chip discharging grooves 11; one end of the air supply pipe 121 is communicated with a gas source. Subsequently, during the use of the machine tool body 1, compressed air can be continuously introduced into the air supply pipe 121 through the gas source, and the compressed air entering the air supply pipe 121 is blown out through a plurality of air blowing nozzles 122 on the air supply pipe 121. The chips and cutting fluid in the chip discharging groove 11 are accelerated to be discharged from the discharge pipe 111 by the compressed air blown out by the plurality of air blowing nozzles 122, which is beneficial to reducing the accumulation of cutting fluid and chips in the chip discharging groove 11.

[0043] Refer to Figure 1 and Figure 2 , the sliding driving member includes two horizontally arranged rodless cylinders 22, and the two rodless cylinders 22 are respectively installed on the two end cavity walls of the inner cavity of the machine tool body 1; a connecting frame 211 is installed at the top of the cleaning air knife 21, and both ends of the connecting frame 211 are respectively connected to the sliders of the two rodless cylinders 22, so that the sliding driving member drives the cleaning air knife 21 to be connected.

[0044] Refer to Figure 4 and Figure 5 , an installation notch is opened at one end of the filter box 32 close to the machine tool body 1, and the discharge pipe 111 extends into the filter box 32 through the installation notch. Two pushing components 13 are arranged at the bottom of the machine tool corresponding to the two filter boxes 32. The pushing component 13 includes a pushing plate 131 and a pushing driving member. The pushing plate 131 is located in the filter box 32 and the pushing plate 131 is located between the discharge pipe 111 and the filtrate plate 321; the bottom of the pushing plate 131 is in contact with the filtrate plate 321 and both ends of the pushing plate 131 respectively extend to the opposite sides of the inner cavity of the filter box 32. The pushing driving member is drivingly connected to the pushing plate 131 and is used to drive the pushing plate 131 to move towards or away from the machine tool frame. Specifically, the pushing driving member includes two horizontally arranged pushing cylinders 132, and the two pushing cylinders 132 are installed at the bottom of the machine tool body 1 through an installation frame 134, and the piston rod ends of the two pushing cylinders 132 are respectively vertically connected to the pushing plate 131.

[0045] With the arrangement of the pushing component 13, subsequently, the pushing plate 131 can be periodically driven by the two pushing cylinders 132 to slide away from the machine tool frame, so as to use the pushing plate 131 to push the chips accumulated on the filtrate plate 321 at the bottom of the filter box 32 towards the end of the filter box 32 away from the machine tool body 1. Reduce the situation that a large amount of chips discharged from the discharge pipe 111 to the filtrate plate 321 accumulate at the bottom of the pipe orifice of the discharge pipe 111, resulting in the influence on the flow of cutting fluid.

[0046] Referring to Figure 4 and Figure 6 , a drying component is further provided at one end of the filter box 32 away from the machine tool body 1. The drying component includes a mounting plate, the mounting plate is supported on the top of the filter box 32, and a plurality of drying fans 322 are mounted on the mounting plate. The drying fans 322 are all arranged towards the inner cavity of the filter box 32. Subsequently, after the pusher driving member drives the pusher plate 131 to push the chips on the filter plate 321 to one end of the filter box 32 away from the machine tool body 1, the drying fans 322 on the mounting plate can continuously blow air towards the stacked chips, so as to blow the cutting fluid adhering to the surface of the chips from the chips, which is beneficial to reducing the residue of the cutting fluid on the surface of the chips and facilitating the better separation of the chips from the cutting fluid.

[0047] Referring to Figure 4 and Figure 5 , a baffle plate 133 is also vertically connected above the pusher plate 131. One end of the baffle plate 133 away from the pusher plate 131 extends to the bottom of the machine tool body 1, and the baffle plate 133 is arranged in contact with the bottom of the discharge pipe 111. Through the arrangement of the baffle plate 133, when the pusher driving member drives the baffle plate 133 to move towards the direction away from the machine tool body 1 to push the chips to one end of the filter box 32 away from the machine tool body 1, the baffle plate 133 can temporarily cover and block the filter plate 321 to limit the chips discharged from the discharge pipe 111 at this time from falling onto the surface of the filter plate 321; on the one hand, it is beneficial to limit the situation that when the pusher driving member drives the pusher plate 131 to move back towards the frame, the pusher plate 131 pushes the chips to one end of the liquid tank 31 close to the machine tool body 1 and slides out of the filter box 32 through the installation notch; on the other hand, it is beneficial for the pusher plate 131 to centrally push the chips to one end of the filter box 32 away from the machine tool body 1, so that the plurality of drying fans 322 at the drying component can better dry the chips. By making the baffle plate 133 be in contact with the bottom of the discharge pipe 111, when the pusher driving member drives the pusher plate 131 to move back towards the machine tool body 1, the chips and cutting fluid accumulated on the baffle plate 133 can be scraped into the filter box 32 in cooperation with the nozzle of the discharge pipe 111, reducing the cutting fluid and chips being carried out of the filter box 32 by the baffle plate 133.

[0048] At the top of the inner cavity of the discharge pipe 111, a discharge air knife 112 is installed. The discharge air knife 112 is communicated with a gas source, and the discharge air knife 112 is arranged obliquely downward towards the pipe orifice of the discharge pipe 111 away from the discharge chute 11. Through the arrangement of the discharge air knife 112, on the one hand, compressed air can be continuously blown into the inner cavity of the discharge air knife 112 through the discharge air knife 112 to assist in accelerating the discharge of the chips and cutting fluid flowing through the discharge pipe 111 from the discharge pipe 111; on the other hand, when the subsequent pusher driving part drives the pusher plate 131 to slide back to its original position, resulting in some chips on the baffle 133 at the top of the pusher plate 131 entering the pipe orifice of the discharge pipe 111, the discharge air knife 112 can blow off this part of the chips from the discharge pipe 111.

[0049] At the top of the liquid tank 31, two installation openings are provided corresponding to the two filter boxes 32. Circular support plates 311 are welded around the installation openings. The bottom of the filter box 32 is lapped on the circular support plates 311, which on the one hand realizes the stable support of the filter box 32 on the liquid tank 31, and on the other hand, facilitates the subsequent lifting of the filter box 32 from the liquid tank 31 to clean the chips filtered in the filter box 32. Handles 323 are installed on both opposite sides of the filter box 32, which is convenient for subsequent lifting of the filter box 32 from the liquid tank 31 through the handles 323. A number of universal wheels 310 are installed at the bottom of the liquid tank 31, which is convenient for subsequent sliding of the liquid tank 31 to drive the filter box 32 away from the discharge pipe 111.

[0050] The implementation principle of the embodiment of this application is as follows: After the numerical control machine tool is used, the cleaning air knife 21 is driven by the sliding driving part in the machine tool body 1 to reciprocate horizontally. The compressed air blown by the cleaning air knife 21 is used to blow the cutting fluid and chips remaining on the surface of the workbench 10 inside the machine tool to the two discharge chutes 11 at the bottom of the machine tool body 1; the cutting fluid and chips falling into the discharge chutes 11 are discharged into the filter box 32 through the discharge pipe 111. The chips are filtered by the filter plate 321, and the cutting fluid falls into the liquid tank 31 through the filter holes on the filter plate 321; it is convenient for the effective cleaning of the cutting fluid remaining on the surface of the workbench 10 and is beneficial to better improving the cleaning efficiency of the cutting fluid on the surface of the workbench 10.

[0051] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
