Description

Technical Field

[0001] The present application relates to the field of cleaning systems, and in particular to an automatic cleaning system for cutting fluid of CNC machine tools. Background Art

[0002] When machining workpieces, CNC machine tools need to continuously spray cutting fluid on the tool and workpiece to cool the workpiece and tool and reduce damage to the tool and 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 around. Most of them will fall into the liquid tank at the bottom of the machine tool, and 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 can easily cause the workbench to rust, affecting the overall processing accuracy of the machine tool. Therefore, after the CNC machine tool is used, it is usually necessary to clean the cutting fluid remaining on the surface of the workbench in time. At present, the cleaning of the residual cutting fluid on the surface of the workbench is usually done by hand-held air gun flushing.

[0004] Regarding the above-mentioned related technologies, on the one hand, the method of manually flushing and cleaning residual cutting fluid with a handheld air gun has low operating efficiency and is inconvenient to operate. On the other hand, during the flushing and cleaning process with the air gun, the cutting fluid is easily splashed onto the exposed skin of the operator, which can easily 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 worktable inside the machine tool, the present application provides an automatic cleaning system for the cutting fluid of a CNC machine tool.

[0006] The present application provides an automatic cleaning system for cutting fluid of a CNC machine tool, which adopts the following technical solution: An automatic cleaning system for cutting fluid of a numerically controlled machine tool, comprising a machine tool body, a cleaning mechanism and a collecting mechanism; A discharge groove is formed at the bottom of the machine tool body; The cleaning mechanism comprises a cleaning air knife and a sliding drive member, wherein the cleaning air knife is located above the working table of the machine tool body, and the air outlet of the cleaning air knife is arranged vertically downward; the sliding drive member is drivingly connected to the cleaning air knife, and is used to drive the cleaning air knife to slide in the horizontal direction; The collecting mechanism includes a liquid trough, which is located on one side of the machine tool body. A filter box is provided on the top of the liquid trough corresponding to the discharge trough. A filtrate plate is provided at the bottom of the filter box, and a plurality of filtrate holes are evenly distributed on the filtrate plate. A discharge pipe is connected to one end of the discharge trough, and the discharge pipe extends into the filter box.

[0007] By adopting the above technical solution, after the CNC machine tool processing is completed, the cleaning air knife is started and driven to move back and forth in the horizontal direction by the sliding drive. The cleaning air knife sprays compressed air to blow the cutting fluid and chips remaining on the worktable surface into the discharge trough at the bottom of the machine tool body, thereby realizing automatic cleaning of the cutting fluid and chips remaining on the worktable surface. After the cutting fluid and chips falling into the discharge trough flow into the filter box through the discharge pipe, the cutting fluid enters the liquid tank through the filter hole on the filter plate at the bottom of the filter box, and the chips are filtered out on the surface of the filter plate, thereby realizing the separation of the cutting fluid and chips. On the one hand, it is convenient to clean the cutting fluid remaining on the worktable surface inside the machine tool body, and on the other hand, it reduces the cutting fluid from splashing onto the exposed skin of the human body during manual cleaning, causing skin allergies and other symptoms.

[0008] Preferably, the discharge trough is arranged to extend obliquely downward, and the discharge pipe is located at the oblique lower end of the discharge trough.

[0009] By adopting the above technical solution, the discharge trough is tilted and extended downward, so that the cutting fluid and chips that subsequently fall into the discharge trough can slide into the discharge pipe by their own gravity, and be discharged into the filter box through the discharge pipe, which is helpful to reduce the accumulation of cutting fluid and chips in the discharge trough.

[0010] Preferably, the inner cavity of the machine tool body is also provided with an auxiliary discharge assembly, which is located at the inclined upper end of the discharge trough. The auxiliary discharge assembly includes an air supply pipe and a plurality of air blowing nozzles. The air blowing nozzles are connected to the air supply pipe, and the plurality of air blowing nozzles are extended obliquely downward toward the discharge trough.

[0011] By adopting the above technical solution and setting up an auxiliary discharge component, compressed gas is subsequently pumped into the air supply pipe and the compressed air is ejected through a number of blowing nozzles on the air supply pipe. A number of blowing nozzles are used to continuously blow compressed air into the discharge trough to assist in blowing the chips and cutting fluid that have fallen and accumulated in the discharge trough into the discharge pipe and discharge them through the discharge pipe, thereby reducing the situation in which a large amount of chips accumulate in the discharge trough, affecting the flow of the cutting fluid in the discharge trough.

[0012] Preferably, a pushing assembly is provided on the top of the machine tool body corresponding to the filter box, and the pushing assembly includes a pushing plate and a pushing driving member, the pushing plate is located in the filter box, and the bottom of the pushing plate abuts against the filtrate plate; the pushing driving member is drivingly connected to the pushing plate, and is used to drive the pushing plate to slide in a direction close to or away from the machine tool body.

[0013] By adopting the above technical solution and setting up the pusher assembly, the pusher plate is subsequently driven to slide in a direction away from the machine tool body by the pusher driving member at regular intervals, and the chips accumulated at the bottom of the discharge pipe are pushed to the end of the filter box away from the machine tool body by the pusher plate, thereby reducing the chips discharged from the discharge pipe from being concentrated at the bottom of the discharge pipe, which would cause the filtrate holes on the filtrate plate to be clogged, thereby affecting the normal passage of the cutting fluid through the filtrate plate, and facilitating the cutting fluid to enter the liquid tank smoothly through the filtrate holes.

[0014] Preferably, the filter box is also provided with a drying component, which is located at one end of the filter box away from the machine tool body. The drying component includes a plurality of drying fans, which are arranged at the top opening of the filter box and are arranged toward the filter box.

[0015] By adopting the above technical solution, a drying fan is used to continuously blow air toward 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 conducive to better separation of the cutting fluid and the chips.

[0016] Preferably, the top of the push plate is bent and connected to a baffle plate, and the baffle plate extends from one end of the discharge pipe to the bottom of the machine tool body; the baffle plate is arranged in abutment with the bottom of the discharge pipe.

[0017] By adopting the above technical solution, through the setting of the baffle plate, in the process of the subsequent push drive driving the push plate to slide in the direction away from the machine tool body, the baffle plate located at the top of the push plate can be temporarily covered to cover the filter plate, so as to limit the chips discharged by the discharge pipe from falling directly onto the filter plate, and avoid the process of the subsequent push drive driving the push plate to slide and reset in the direction close to the machine tool body, the push plate pushes the chips on the filter plate to the end of the filter box close to the machine tool body, which is conducive to the pusher assembly to push the chips to the 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 off the chips. By making the baffle plate abut against the top of the discharge pipe, in the process of the subsequent push drive driving the push plate to slide and reset in the direction close to the machine tool body, the discharge pipe can be cooperated to push the chips and cutting fluid that fall on the baffle plate onto the filter plate, so as to limit the chips and cutting fluid from remaining on the baffle plate and being driven to the bottom of the machine tool.

[0018] Preferably, a discharge air knife is arranged at the top of the inner cavity of the discharge pipe, and the discharge air knife extends obliquely downward toward the pipe opening at one end of the discharge pipe away from the discharge trough.

[0019] By adopting the above technical solution and setting the discharge air knife, the compressed air flow is continuously blown into the discharge pipe through the discharge air knife to assist the cutting fluid flowing through the discharge pipe and accelerate the discharge of the cutting fluid out of the discharge pipe. At the same time, it is helpful to reduce the chips on the baffle plate entering and accumulating at the mouth of the discharge pipe when the subsequent pushing drive drives the pushing plate to drive the baffle plate to slide and reset in the direction close to the machine tool body.

[0020] Preferably, a mounting opening is provided on the top of the liquid tank corresponding to the filter box, an annular support plate is installed at the mounting opening, and the bottom of the filter box is overlapped on the annular support plate.

[0021] By adopting the above technical solution, by overlapping the bottom of the filter box on the annular support plate, the filter box can be stably supported above the liquid tank. When cleaning the chips filtered out of the filter box later, the filter box can be removed from the liquid tank to facilitate the cleaning of the chips filtered out of the filter box.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When cleaning the cutting fluid remaining on the worktable inside the machine tool body, the cleaning air knife is driven to reciprocate in the horizontal direction by the sliding drive of the cleaning mechanism, and the compressed air flow blown by the cleaning air knife is used to blow the cutting fluid and chips remaining on the surface of the worktable to the discharge trough, and discharged into the filter box through the discharge pipe at the end of the discharge trough. 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, so that the cutting fluid and chips are effectively separated while the residual cutting fluid on the worktable inside the machine tool is automatically cleaned.

[0023] 2. By arranging an auxiliary discharge component at the inclined upper end of the discharge trough, the compressed air is continuously blown toward the discharge trough through the air supply pipe of the auxiliary discharge component in conjunction with a number of blowing nozzles to accelerate the discharge of the cutting fluid and chips in the discharge trough through the discharge pipe to the outside of the discharge trough, thereby reducing the accumulation of chips in the discharge trough, which affects the normal flow of the cutting fluid.

[0024] 3. By arranging a pusher assembly at the bottom of the machine tool and arranging a drying assembly at the end of the filter box away from the machine tool body, the pusher plate can be driven to move in a direction away from the machine tool body by the pusher drive member at regular intervals, so that the chips accumulated at the bottom of the discharge pipe can be pushed to the end of the filter box away from the machine tool body by the pusher plate, thereby reducing the situation in which the normal flow of the cutting fluid is affected by the accumulation of a large amount of chips at the bottom of the discharge pipe; at the same time, after the chips are pushed to the end of the filter box away from the machine tool body by the pusher plate, they can be continuously blown by the drying assembly, so that the cutting fluid remaining on the chips can be separated from the chips and fall into the liquid tank, which is conducive to further realizing the effective separation of the cutting fluid and the chips.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] The present application embodiment discloses an automatic cleaning system for cutting fluid of a CNC machine tool, referring to Figure 1 and Figure 2, including a machine tool body 1, a cleaning mechanism 2 and a collecting mechanism 3; two discharge grooves 11 are formed at the bottom of the machine tool body 1; the cleaning mechanism 2 is located in the inner cavity of the machine tool body 1; the cleaning mechanism 2 includes a cleaning air knife 21 and a sliding drive member; the cleaning air knife 21 is connected to the air source, the cleaning air knife 21 is located above the workbench 10 and the air outlet of the cleaning air knife 21 is vertically arranged downward; the collecting 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 the discharge groove 11 is connected to 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 the end of the corresponding filter box 32 close to the machine tool body 1; the bottom of the filter box 32 is opened, and the bottom opening of the filter box 32 is covered with a filter plate 321 for filtering out chips, and a plurality of filter holes are evenly opened on the filter plate 321.

[0034] After the machine tool body 1 is used, the cleaning air knife 21 is driven to reciprocate in the horizontal direction by the sliding drive part, 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 trough 11, thereby realizing 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 trough 11 are discharged into the filter box 32 through the discharge pipe 111, and the chips entrained in the cutting fluid are filtered out through the filter plate 321, and the remaining cutting fluid flows into the liquid tank 31 through the filter holes on the filter plate 321, thereby realizing effective separation of the cutting fluid and the chips.

[0035] The two discharge grooves 11 extend downwardly from the direction away from the liquid groove 31 to the direction close to the liquid groove 31, and the discharge pipes 111 are located at the inclined lower ends of the corresponding discharge grooves 11. Through the above arrangement, it is convenient for the cutting fluid and chips that fall into the discharge groove 11 to slide to the inclined lower ends of the discharge groove 11 by their own gravity and be discharged through the discharge pipes 111.

[0036] Reference Figure 1 and Figure 3Two auxiliary discharge assemblies 12 are arranged in the inner cavity of the machine tool body 1 corresponding to the two discharge grooves 11; the auxiliary discharge assembly 12 is located at the inclined upper end of the corresponding discharge groove 11; the auxiliary discharge assembly 12 includes 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; the air supply pipe 121 is evenly installed with a plurality of blowing nozzles 122 along its own extension direction, and the blowing nozzles 122 are all arranged obliquely downward toward the corresponding discharge groove 11; one end of the air supply pipe 121 is connected to the air source, and during the subsequent use of the machine tool body 1, compressed air can be continuously introduced into the air supply pipe 121 through the air source, and the compressed air entering the air supply pipe 121 is blown out through the plurality of blowing nozzles 122 on the air supply pipe 121, and the plurality of compressed air blown out by the plurality of blowing nozzles 122 accelerates the chips and cutting fluid in the discharge groove 11 to be discharged from the discharge pipe 111, which is beneficial to reduce the accumulation of cutting fluid and chips in the discharge groove 11.

[0037] Reference Figure 1 and Figure 2 The sliding drive component includes two horizontally arranged rodless cylinders 22, and the two rodless cylinders 22 are respectively installed on the cavity walls at both ends of the inner cavity of the machine tool body 1; a connecting frame 211 is installed on the top of the cleaning air knife 21, and the two ends of the connecting frame 211 are respectively connected to the slides of the two rodless cylinders 22, so that the sliding drive component is driven and connected to the cleaning air knife 21.

[0038] Reference Figure 4 and Figure 5 , a mounting notch is provided 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 mounting notch. Two pusher assemblies 13 are provided at the bottom of the machine tool corresponding to the two filter boxes 32. The pusher assembly 13 includes a pusher plate 131 and a pusher drive member. The pusher plate 131 is located in the filter box 32 and between the discharge pipe 111 and the filtrate plate 321; the bottom of the pusher plate 131 is arranged in contact with the filtrate plate 321 and the two ends of the pusher plate 131 extend to the opposite sides of the inner cavity of the filter box 32 respectively. The pusher drive member is drivingly connected to the pusher plate 131, and is used to drive the pusher plate 131 to move toward or away from the machine tool frame. Specifically, the push drive member includes two horizontally arranged push cylinders 132 , which are mounted on the bottom of the machine tool body 1 through a mounting frame 134 , and the piston rod ends of the two push cylinders 132 are vertically connected to the push plates 131 .

[0039] With the arrangement of the push assembly 13, the push plate 131 can be driven to slide away from the machine tool frame periodically through two push cylinders 132, so as to use the push plate 131 to push the chips accumulated on the filter plate 321 at the bottom of the filter box 32 to the end of the filter box 32 away from the machine tool body 1. This reduces the situation where a large amount of chips discharged from the discharge pipe 111 to the filter plate 321 are accumulated at the bottom of the discharge pipe 111, which affects the flow of the cutting fluid.

[0040] Reference Figure 4 and Figure 6 A drying component is also provided at one end of the filter box 32 away from the machine tool body 1, and the drying component includes a mounting plate, which is supported on the top of the filter box 32, and a plurality of drying fans 322 are installed on the mounting plate, and the drying fans 322 are all arranged toward the inner cavity of the filter box 32. Subsequently, after the pushing plate 131 is driven by the pushing driving member to push the chips on the filtrate plate 321 to the end of the filter box 32 away from the machine tool body 1, the drying fan 322 on the mounting plate can continuously blow air toward the accumulated chips to blow away the cutting fluid adhering to the surface of the chips from the chips, which is beneficial to reduce the residual cutting fluid on the surface of the chips and facilitates better separation of the chips and the cutting fluid.

[0041] Reference Figure 4 and Figure 5 A baffle plate 133 is vertically connected above the push plate 131 , and one end of the baffle plate 133 away from the push plate 131 extends to the bottom of the machine tool body 1 , and the baffle plate 133 is disposed in contact with the bottom of the discharge pipe 111 . By setting the baffle plate 133, when the subsequent pushing drive member drives the baffle plate 133 to move in a direction close to and away from the machine tool body 1 to push the chips to the end of the filter box 32 away from the machine tool body 1, the baffle plate 133 can be used to temporarily cover 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 in which the pusher plate 131 pushes the chips to the 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 during the subsequent pushing drive member drives the pusher plate 131 to move in a direction close to the frame and reset; on the other hand, it is beneficial for the pusher plate 131 to concentrate the chips to the end of the filter box 32 away from the machine tool body 1, so that the multiple drying fans 322 at the drying component can better dry the chips. By making the baffle plate 133 abut against the bottom of the discharge pipe 111, when the subsequent pushing drive component drives the pushing plate 131 to move towards the direction close to the machine tool body 1 to reset, the discharge pipe 111 can cooperate with the pipe mouth to scrape the chips and cutting fluid accumulated on the baffle plate 133 into the filter box 32, thereby reducing the cutting fluid and chips being carried out of the filter box 32 by the baffle plate 133.

[0042] A discharge air knife 112 is installed at the top of the inner cavity of the discharge pipe 111. The discharge air knife 112 is connected to the air source and is arranged downwardly and obliquely toward the end of the discharge pipe 111 away from the discharge trough 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 push drive member drives the push plate 131 to slide and reset, causing part of the chips on the top baffle plate 133 of the push plate 131 to enter the tube mouth of the discharge pipe 111, the part of the chips can be blown off from the discharge pipe 111 through the discharge air knife 112.

[0043] Two installation openings are provided at the top of the liquid tank 31 corresponding to the two filter boxes 32. The installation openings are surrounded by an annular support plate 311 welded therearound. The bottom of the filter box 32 is overlapped on the annular support plate 311. On the one hand, the filter box 32 is stably supported on the liquid tank 31. On the other hand, it is convenient to lift the filter box 32 from the liquid tank 31 to clean the chips filtered out of the filter box 32. Handles 323 are installed on the opposite sides of the filter box 32 to facilitate the subsequent lifting of the filter box 32 from the liquid tank 31 by the handles 323. A number of universal wheels 310 are installed at the bottom of the liquid tank 31 to facilitate the subsequent sliding of the liquid tank 31 to drive the filter box 32 to separate from the discharge pipe 111.

[0044] The implementation principle of the embodiment of the present application is: after the CNC machine tool is used, the cleaning air knife 21 is driven to reciprocate in the horizontal direction by the sliding drive member in the machine tool body 1, and 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 worktable 10 inside the machine tool into the two discharge grooves 11 at the bottom of the machine tool body 1; the cutting fluid and chips falling into the discharge groove 11 are discharged into the filter box 32 through the discharge pipe 111, the chips are filtered out 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 to effectively clean the cutting fluid remaining on the surface of the worktable 10, which is conducive to better improving the cleaning efficiency of the cutting fluid on the surface of the worktable 10.
