[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings. They are also core equipment in the field of machining, widely used in cutting, drilling, milling and other machining processes of various parts. During the machining process, cutting fluid is usually used for cooling and lubrication, and a large amount of metal chips are generated.

[0003] However, existing CNC machine tools still have the following technical problems in actual use: the mixing and discharge of cutting fluid and chips is a common method, but existing machine tools lack efficient separation and collection structures; after chips and cutting fluid are mixed, it not only increases the difficulty of subsequent processing, but also reduces the recycling rate of cutting fluid; although some machine tools are equipped with filtration devices, the structure is simple, the separation effect is not ideal, and cleaning and maintenance are inconvenient; in addition, after machining, it is difficult to thoroughly clean the chips and cutting fluid remaining inside the machine tool, especially in the machining area; traditional manual cleaning methods are inefficient and labor-intensive, while existing automatic cleaning devices mostly use fixed nozzles, which have a limited cleaning range and cleaning dead corners, affecting the cleaning effect of the machine tool and the accuracy of subsequent machining. Summary of the Invention

[0004] The purpose of this invention is to provide a CNC machine tool for machining, which adopts a two-stage filtration structure to effectively intercept metal chips of different sizes; at the same time, it can flexibly adjust the spray position and angle according to the residue in the machining area, significantly expanding the cleaning coverage, effectively eliminating cleaning blind spots inside the machine tool, and improving automated cleaning capabilities, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CNC machine tool for machining, comprising a CNC machine tool body:

[0006] The surface of the CNC machine tool body is provided with a shielding component for preventing splashing. The bottom of the inner cavity of the CNC machine tool body is provided with an installation groove. The inside of the installation groove is provided with a collection mechanism for separation and collection. The collection mechanism includes a support component disposed inside the installation groove and an outward discharge component connected to the bottom of the support component. The inside of the support component is provided with a first separation component and a second separation component connected to the bottom of the first separation component.

[0007] The top of the back of the CNC machine tool body is provided with a cleaning mechanism for rinsing and cleaning. The cleaning mechanism includes a connecting component located on the back of the CNC machine tool body and a push-pull component connected to the connecting component. One end of the push-pull component is provided with a rotating component and a water spraying component connected to the rotating component.

[0008] For example, the shielding assembly includes a guide rail fixedly installed on the top and surface of the CNC machine tool body, and a shielding cover and a visible transparent glass plate fixedly installed on the surface of the shielding cover are slidably connected inside the guide rail.

[0009] For example, the support component includes a mounting frame fixedly installed on the inner sidewall of the mounting groove, and a connecting ring is fixedly installed on the inner sidewall of the mounting frame.

[0010] For example, the external drainage component includes a liquid collection hopper fixedly installed at the bottom of the mounting frame and a drainage pipe communicating with the bottom of the liquid collection hopper, the drainage end of the drainage pipe extending to the outside of the CNC machine tool body.

[0011] For example, the first separation component includes a filter frame placed on top of the connecting ring, and a pressure plate and screws threaded to both ends of the top of the pressure plate are mounted on the top of the mounting frame.

[0012] For example, the second separation component includes vertical plates fixedly installed at both ends of the bottom of the filter frame, and a filter plate is fixedly installed at the bottom of the vertical plates.

[0013] For example, the connection component includes a mounting box fixedly installed on the back of the internal cavity of the CNC machine tool body, and a water supply pipe is fixedly installed at one end of the mounting box.

[0014] For example, the push-pull assembly includes an electric push rod fixedly installed on one side of the mounting box cavity, and a telescopic rod fixedly installed on the other side of the mounting box cavity.

[0015] For example, the rotating assembly includes a motor fixedly mounted on the output end of the electric push rod and a connecting block fixed to one side of the motor, the connecting block being fixed to the extension end of the telescopic rod.

[0016] For example, the water spray assembly includes a hollow rotor keyed to the output shaft of a motor and a water spray hole opened on the outside of the hollow rotor. A rotary joint and a hose connected to the top of the rotary joint are connected at the center of the top of the hollow rotor. The water inlet end of the hose is connected to the drain end of the water supply pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention utilizes a collection mechanism installed in the mounting groove at the bottom of the CNC machine tool body, and employs a two-stage filtration structure consisting of a first separation component and a second separation component to effectively intercept metal chips of different sizes. The cutting fluid, after being filtered sequentially through a filter frame and filter plate, is then centrally discharged or recycled via a collection hopper and drain pipe, achieving efficient separation of chips and cutting fluid. This structure not only improves the recycling rate of cutting fluid but also significantly reduces the difficulty and cost of subsequent waste fluid treatment. The cleaning mechanism uses a push-pull assembly consisting of an electric push rod and a telescopic rod, combined with a motor-driven hollow rotary wheel and water spray holes, to achieve reciprocating movement and rotating spraying of the water spray assembly in the horizontal direction.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, the present invention provides a CNC machine tool for machining, including a CNC machine tool body 1:

[0029] The surface of the CNC machine tool body 1 is provided with a shielding component 2 for preventing splashing. The bottom of the inner cavity of the CNC machine tool body 1 is provided with an installation groove 5. The inside of the installation groove 5 is provided with a collection mechanism 4 for separation and collection. The collection mechanism 4 includes a support component disposed inside the installation groove 5 and an outward discharge component connected to the bottom of the support component. The inside of the support component is provided with a first separation component and a second separation component connected to the bottom of the first separation component.

[0030] A cleaning mechanism 3 for rinsing and cleaning is provided on the top of the back of the CNC machine tool body 1. The cleaning mechanism 3 includes a connecting component provided on the back of the CNC machine tool body 1 and a push-pull component connected to the connecting component. One end of the push-pull component is provided with a rotating component and a water spraying component connected to the rotating component.

[0031] Preferably, the shielding component 2 includes a guide rail 21 fixedly installed on the top and surface of the CNC machine tool body 1. A shielding cover 22 and a transparent glass plate 23 fixedly installed on the surface of the shielding cover 22 are slidably connected inside the guide rail 21. The guide rail 21 is used to support and guide the sliding of the shielding cover 22. At the same time, the shielding cover 22 can shield and protect the operation. The transparent glass plate 23 is used to allow the internal processing to be viewed when the shielding cover 22 is shielded and protected.

[0032] It is worth noting that the support assembly includes a mounting frame 41 fixedly installed on the inner wall of the mounting groove 5. A connecting ring 44 is fixedly installed on the inner wall of the mounting frame 41. The mounting frame 41 and the connecting ring 44 on the inner wall facilitate the installation of the first separation assembly.

[0033] Furthermore, the external discharge assembly includes a liquid collection hopper 48 fixedly installed at the bottom of the mounting frame 41 and a discharge pipe 49 communicating with the bottom of the liquid collection hopper 48. The discharge end of the discharge pipe 49 extends to the outside of the CNC machine tool body 1. The liquid collection hopper 48 is used to collect the filtered liquid above and can discharge it to external containers and pipes through the discharge pipe 49.

[0034] Furthermore, the first separation component includes a filter frame 45 placed on top of the connecting ring 44. A pressure plate 42 and a screw 43 threadedly connected to both ends of the top of the pressure plate 42 are installed on the top of the mounting frame 41. The filter frame 45 is used for preliminary filtration. The pressure plate 42 is tightened by the screw 43 to secure the filter frame 45. Threaded holes are provided on the top of the pressure plate 42 and the corresponding positions of the screw 43 to facilitate threaded connection.

[0035] In addition, the second separation component includes vertical plates 46 fixedly installed at both ends of the bottom of the filter frame 45. A filter plate 47 is fixedly installed at the bottom of the vertical plates 46. The vertical plates 46 can support the filter plate 47, and the filter plate 47 can perform secondary filtration and separation, thereby improving the solid-liquid separation effect and facilitating the separation and treatment of waste chips and waste liquid.

[0036] It is worth noting that the connecting components include a mounting box 31 fixedly installed on the back of the inner cavity of the CNC machine tool body 1. A water supply pipe 310 is fixedly installed at one end of the mounting box 31. The mounting box 31 is used to support the internal structure, while the water supply pipe 310 can be connected to an external water supply device to supply water to the inside of the water supply pipe 310.

[0037] The push-pull assembly includes an electric push rod 32 fixedly installed on one side of the inner cavity of the mounting box 31, and a telescopic rod 33 fixedly installed on the other side of the inner cavity of the mounting box 31. The electric push rod 32 can drive the motor 34 to extend and adjust its required position, while the telescopic rod 33 will be indirectly driven to stretch, playing an auxiliary support role to ensure the stability during the push-pull process.

[0038] In addition, the rotating assembly includes a motor 34 fixedly installed at the output end of the electric push rod 32 and a connecting block 35 fixed to one side of the motor 34. The connecting block 35 is fixed to the extension end of the telescopic rod 33. The motor 34 is used to adjust the water spray direction of the top hollow wheel 36 to improve the uniformity and effect of rinsing. The connecting block 35 facilitates the extension and retraction of the telescopic rod 33 when the motor 34 moves.

[0039] Finally, the water spray assembly includes a hollow rotor 36 keyed to the output shaft of the motor 34 and a water spray hole 37 opened on the outside of the hollow rotor 36. A rotary joint 38 and a hose 39 connected to the top of the rotary joint 38 are connected at the center of the top of the hollow rotor 36. The water inlet end of the hose 39 is connected to the drain end of the water supply pipe 310.

[0040] The hose 39 can deliver the liquid from the water supply pipe 310 to the hollow rotary wheel 36. During the delivery process, it will pass through the rotary joint 38. Based on the setting of the rotary joint 38, the hollow rotary wheel 36 can be rotated without the hose 39 getting tangled during rotation, and the liquid delivery can also be guaranteed. When the hollow rotary wheel 36 is driven to rotate, it will spray the delivered liquid onto the inner wall of the CNC machine tool body 1 through the water spray hole 37, thereby realizing the flushing and cleaning operation.

[0041] First, before processing, the workpiece needs to be placed inside the CNC machine tool body 1, and then the CNC machine tool body 1 is controlled to perform processing operations.

[0042] During the processing, the operator moves the sliding cover 22 along the guide rail 21 to achieve closed protection of the processing area and prevent cutting fluid and chips from splashing; the visible transparent glass plate 23 allows for real-time observation of the internal processing status.

[0043] Meanwhile, during the machining process, the cutting fluid and chips fall naturally into the mounting tank 5, where the collection mechanism 4 automatically completes the solid-liquid separation. First, the fluid undergoes preliminary filtration through the filter screen frame 45 to intercept larger chip particles. Then, the liquid continues to fall and undergoes secondary fine filtration through the filter screen plate 47 to further improve the solid-liquid separation effect. The filtered cutting fluid flows into the collection hopper 48 and is finally discharged outside the machine tool through the drain pipe 49 for easy recycling or centralized treatment. The mounting frame 41 and the connecting ring 44 are used to fix the separation components, and the pressure plate 42 and the screw 43 are used for clamping and positioning.

[0044] When pressing, the filter screen frame 45 and filter screen plate 47 are placed. At this time, the pressure plate 42 needs to be pressed on the top center of the filter screen frame 45. Then, the screw 43 is taken out and threadedly connected to it. The screw continues to extend downward, causing the pressure plate 42 to press downward and fix it, thereby achieving the pressing and fixing.

[0045] By setting a two-stage filtration structure in the installation tank 5, efficient separation of chips and cutting fluid is achieved; the separated cutting fluid can be recycled and reused, reducing cutting fluid consumption and waste discharge, and lowering production costs and environmental burden.

[0046] After processing, external water supply enters the hose 39 through the water supply pipe 310, and then is sent into the hollow wheel 36 through the rotary joint 38; the electric push rod 32 drives the motor 34 and the hollow wheel 36 to move horizontally, and the telescopic rod 33 provides auxiliary support and maintains stability; at the same time, the motor 34 drives the hollow wheel 36 to rotate, and the water spray hole 37 sprays high-pressure water onto the inner wall of the machine tool and the processing area to achieve thorough cleaning; the mounting box 31 is used to accommodate the push-pull and rotating components;

[0047] By controlling the extension and retraction of the electric push rod 32 and the rotation angle of the motor 34, the inside of the machine tool is thoroughly cleaned; the wastewater after cleaning falls back into the collection mechanism 4 for filtration and discharge.

[0048] By utilizing the combined push-pull and rotation motion of the cleaning mechanism 3, a comprehensive automatic cleaning of the internal processing area of ​​the machine tool is achieved, avoiding blind spots and labor intensity associated with manual cleaning. At the same time, the filter frame 45 and filter plate 47 adopt a detachable structure, allowing users to quickly remove and clean them, significantly improving daily maintenance efficiency.

[0049] The liquid collection hopper 48 adopts a conical structure that is wider at the top and narrower at the bottom, which facilitates the downward flow of the filtered cutting fluid and reduces liquid residue; the outlet of the drain pipe 49 can be connected to an external waste liquid collection tank or a cutting fluid recycling system as needed.

[0050] The pressure plate 42 presses down on the filter screen frame 45 to prevent it from shifting or jumping under the impact of the cutting fluid;

[0051] The height design of the vertical plate 46 creates a certain liquid storage gap between the filter plate 47 and the filter frame 45, preventing liquid from directly impacting the filter plate 47 and causing blockage. Through two-stage filtration, the removal rate of solids in the cutting fluid is significantly improved, which is beneficial for the recycling and reuse of the cutting fluid.

[0052] In actual maintenance, the operator can first unscrew the screw 43, remove the pressure plate 42, and then lift the filter screen frame 45, vertical plate 46 and filter screen plate 47 in sequence to clean or replace the filter screen; the operation is simple and the maintenance efficiency is high; the operator can open the cover 22 regularly according to the type of processed material and the amount of chips generated, take out the filter screen frame 45 and filter screen plate 47 to clean the chips and avoid clogging;

[0053] The rotary joint 38 adopts a high-pressure resistant and wear-resistant mechanical seal structure, which can ensure that the hose 39 does not get tangled when the hollow wheel 36 rotates continuously, and the water supply is stable.

[0054] After cleaning, the electric push rod 32 retracts completely, pulling the hollow rotary wheel 36 back into the mounting box 31 to avoid affecting the next processing. The operator can observe the cleaning effect through the visible transparent glass plate 23 and restart the cleaning program if necessary.

[0055] The two-stage filtration structure, consisting of a first separation component and a second separation component, can effectively intercept metal chips of different sizes. After the cutting fluid is filtered sequentially through the filter frame 45 and the filter plate 47, it is discharged or recycled through the collection hopper 48 and the drain pipe 49, achieving efficient separation of chips and cutting fluid. This structure not only improves the recycling rate of cutting fluid, but also significantly reduces the difficulty and cost of subsequent waste liquid treatment.

[0056] The push-pull assembly, consisting of an electric push rod 32 and a telescopic rod 33, along with a hollow rotating wheel 36 driven by a motor 34 and a water spray hole 37, enables the water spray assembly to reciprocate and rotate in the horizontal direction. Compared with the existing fixed nozzle structure, it can flexibly adjust the spray position and angle according to the residue in the processing area, significantly expand the cleaning coverage, effectively eliminate cleaning blind spots inside the machine tool, improve automated cleaning capabilities, and reduce the frequency of manual intervention.
