Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a CNC machining center with a table cleaning function. Background Art

[0002] CNC machining center usually refers to precision machining using computer numerical control technology, including CNC lathes, CNC milling machines and CNC boring machines.

[0003] Compared with traditional machining machines, CNC machine tools use automatic control and do not rely on the operator's experience, making the processed parts more precise. However, CNC machining centers also have certain limitations during use. Due to the low level of human involvement and the inability to perform real-time cleaning, the debris generated during the machining process may accumulate on the table, which will affect the positioning machining accuracy to a certain extent.

[0004] In addition, when performing CNC machining, it is generally necessary to use liquid to cool the tool and workpiece to prevent the temperature from being too high, which will affect the machining accuracy and cause some debris to adhere to the table surface through the liquid, making cleaning inconvenient. Summary of the invention

[0005] The object of the present invention is to provide a CNC machining center with a table cleaning function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: The CNC machining center includes a machine tool, a drive device, a chip removal device and a collecting device. The drive device is connected to the machine tool, the drive device is connected to the chip removal device through transmission, the chip removal device is connected to the machine tool, the chip removal device and the collecting device are connected through pipelines, the collecting device and the machine tool are firmly connected, and the chip removal device sprays arc-shaped liquid to sweep away the chips.

[0007] The machine tool is used to provide an installation base and processing space. It is controlled by a computer numerical control system to perform high-precision and high-efficiency processing. The drive device is the main power source, used to provide power for various processing techniques. The debris generated by the processing is collected by the chip removal device to achieve the effect of automatic cleaning of the table. The debris is separated by the collection device to facilitate the recycling of the liquid. During CNC processing, the liquid is sprayed outward through the chip removal device to form an arc surface, thereby attenuating the speed of the centrifugal debris during the processing to prevent the debris from splashing.

[0008] Furthermore, the machine tool includes a bed, a cross module and a lifter, the bed is provided with a cross module, the cross module is spatially arranged, the upper module output end of the cross module is provided with a carrier, the lifter is tightly connected to the bed, the lift output end is provided with a machine base, and the machine base is connected to a chip removal device; The chip removal device includes a guide seat, which includes a diverter ring and a base ring. The base ring is tightly connected to the machine base. The base ring is provided with an annular groove. The upper end of the diverter ring is inserted into the annular groove. The diverter ring is provided with a plurality of centrifugal grooves. The centrifugal grooves are spirally arranged. The spiral diameter of the centrifugal grooves gradually decreases from top to bottom. The outlets of the plurality of centrifugal grooves are combined to form a whole circle. The inlet of the centrifugal groove is connected to the liquid containing debris.

[0009] The bed adopts a vertical design. By setting a cross module, the carrier is driven to move horizontally in the processing space of the bed. The cross module adopts a conventional module design and is used to output linear displacement. Through the two crossed directions, it is convenient to drive the carrier to move, thereby driving the workpiece to move, and facilitating the processing of various positions of the workpiece. By setting a lift, the lift can be in the form of a screw nut, or a chain transmission structure, so that its output end drives the machine base to move vertically. The flow is diverted by the guide seat, and the base ring is fixed on the machine base and can move with the machine base. An annular groove is arranged on the base ring to install the diverter ring. A number of spirally arranged centrifugal grooves are arranged on the diverter ring. The centrifugal groove inlet is connected to the liquid containing debris. When the impure liquid spirals downward along the centrifugal groove, due to the large density of the impurity particles, it flows along the outer layer of the centrifugal groove under the action of centrifugal force, and the liquid flows along the inner layer of the centrifugal groove. The spiral diameter is arranged to decrease from top to bottom, so that the centrifugal force on the impurity particles during the downward process of the centrifugal groove gradually increases, and finally sprays out along the end of the circle to form a water curtain. The formed water curtain is arranged along the circumference of the driving device. The debris generated in the processing process is tilted to the circumference by the centrifugal force. The water body in the inner layer impacts the debris through the water curtain, so that the debris speed is attenuated. The density of the impurity water body in the outer layer is relatively high, so that the debris after the speed is attenuated cannot break through the outer layer of the water curtain, and is carried downward by the water curtain to clean the table.

[0010] Furthermore, the chip removal device also includes a separation component and a booster pump. Drainage grooves are respectively provided on both sides of the bed, and a screening chamber is provided at the end of the drainage groove. The separation component is placed in the screening chamber. The separation component includes a lifting pump and a lifting seat. The lifting pump inlet is connected to the drainage groove. The lifting seat is provided with a guide slope. The guide slope is close to one end of the lifting pump as a low end. The output end of the lifting pump faces the guide slope. A number of material dropping grooves are provided on the lower side of the guide slope. A accommodating groove is provided at the end of the guide slope. The inlet of the booster pump is connected to the accommodating groove, the outlet of the booster pump is connected to the annular groove, and the centrifugal groove is set to open on one side of the annular groove.

[0011] The water after the water curtain impacts the debris is collected through the drainage grooves on both sides and introduced into the lifting pump. The water is pressurized by the lifting pump to accelerate the flow rate of the ejected water and spray it along the diversion slope. When the water flows upward along the diversion slope, this flow path is defined as the screening stroke. The blanking trough is located in the second half of the screening stroke. When the water flows along the diversion slope, the friction between the impurities with larger mass and the diversion slope is greater than the friction between the water, the small particle impurities and the diversion slope, so that the large particle impurities fall into the blanking trough under the action of gravity when flowing to the blanking trough, and most of the water and the small particle impurities will cross the inlet of the blanking trough under the action of inertia, enter the subsequent stroke, and finally enter the containing tank to form a liquid containing impurities. The liquid containing impurities is pumped into the annular groove by the booster pump and flows to the centrifugal groove, which is convenient for forming a water curtain, preventing large particle impurities from entering the stage of forming the water curtain, and reducing the erosion and wear of the table surface.

[0012] Furthermore, the driving device includes a driving motor and a tool. A driving cavity is provided on the machine base. The driving motor is placed in the driving cavity. The output end of the driving motor is firmly connected to the tool.

[0013] The drive motor is fixed through the drive cavity on the machine base. The drive motor serves as the main drive source to drive the tool to rotate. The lower end of the drive cavity is opened so that the output end of the drive motor can extend out of the drive cavity to facilitate tool changing.

[0014] Furthermore, the driving device also includes a gear ring, and the guide seat also includes a middle gear. The diverter ring is provided with a knife groove, and a tooth groove is provided along the wall of the knife groove. The gear ring is tightly connected to the output end of the driving motor, and a middle axis bracket is provided at the upper end of the middle gear. The middle gear is connected to the base ring through the middle axis bracket, and the gear ring is meshed with the tooth surface of the tooth groove through the middle gear, and the diverter ring and the ring groove are rotatably connected.

[0015] A gear ring is arranged at the output end of the driving motor. When the workpiece is processed by the tool, the gear ring is driven to rotate at the same time. The middle gear is installed on the base ring through the middle shaft bracket. The middle gear and the middle shaft bracket are rotatably connected. When the gear ring and the middle gear are meshed, the meshing transmission of the middle gear and the tooth groove drives the diverter ring to rotate. The speed of the diverter ring is reduced through the two-stage transmission. During the rotation of the diverter ring, the impurity liquid in the centrifugal tank is driven to be discharged and centrifuged outward at an angle, so as to form a cone-like water curtain and improve the cleaning effect of the processing debris.

[0016] Furthermore, the spiral direction of the centrifugal groove is the same as the rotation direction of the diverter ring.

[0017] By rotating in the same direction, the impurity-containing liquid is centrifuged outward when flowing out of the centrifugal groove, thereby expanding the range of the water curtain and avoiding impact on the workpiece and affecting the cleaning quality.

[0018] As an optimization, the collection device includes a collection box, which is tightly connected to the bed, and a collection trough is provided on the collection box. The separation assembly also includes a chip discharge pipe, the inlet of the chip discharge pipe is connected to the material dropping trough, and the outlet of the chip discharge pipe faces the collection trough. By setting the collection box, when the water body passes over the material dropping trough, part of the water body enters the chip discharge pipe from the material dropping trough along with the large particles of debris, and is sent to the collection trough through the chip discharge pipe, which is convenient for collection.

[0019] As an optimization, a water collection tank is provided on the collection box, the upper end of the water collection tank is connected to the collection tank, and a screen is provided at the connection between the water collection tank and the collection tank. Through the double-cavity setting of the collection box, after the water containing large particles of debris enters the water collection tank, the water falls into the water collection tank through the screen under the action of gravity, and the large particles of debris cannot pass through the screen, thereby automatically separating the large particles of debris.

[0020] As an optimization, the driving device also includes a tool changer, and the tool changer is firmly connected to the bed. By setting the tool changer, the tool changer can be driven by a motor to rotate the required tool to the bottom, which is convenient for automatic tool change.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the inlet of the centrifugal groove is connected to the liquid containing debris. When the impurity-containing liquid spirals downward along the centrifugal groove, due to the large density of the impurity particles, it flows along the outer layer of the centrifugal groove under the action of centrifugal force, and the liquid flows along the inner layer of the centrifugal groove. The spiral diameter is arranged to decrease from top to bottom, so that the centrifugal force to which the impurity particles are subjected during the downward process of the centrifugal groove gradually increases, and finally they are ejected along the end that forms a full circle to form a water curtain. The formed water curtain is arranged along the circumference of the driving device, and the debris generated in the processing process is tilted and scattered in the circumferential direction under the action of the centrifugal force. Through the water curtain, the water body in the inner layer impacts the debris, so that the speed of the debris is attenuated. The density of the impurity-containing water body in the outer layer is relatively high, so that the debris after the speed is attenuated cannot break through the outer layer of the water curtain. , and is carried downward by the water curtain to clean the table surface; when the water body flows upward along the diversion slope, this flow path is defined as the screening stroke, and the blanking trough is located in the second half of the screening stroke. When the water body flows along the diversion slope, the friction between the impurities with larger mass and the diversion slope is greater than the friction between the water body, the small particle impurities and the diversion slope, so that when the large particle impurities flow to the blanking trough, they fall into the blanking trough under the action of gravity, while most of the water body and the small particle impurities will cross the blanking trough inlet under the action of inertia, enter the subsequent stroke, and finally enter the containing tank to form a liquid containing impurities. The liquid containing impurities is pumped into the annular groove by the booster pump and flows to the centrifugal groove, which is convenient for forming a water curtain, preventing large particle impurities from entering the stage of forming the water curtain, and reducing the erosion and wear of the table surface.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example: Figure 1-Figure 7 As shown, the present invention provides a technical solution for a CNC machining center with a table cleaning function.

[0026] The CNC machining center includes a machine tool 1, a drive device 2, a chip removal device 3 and a collecting device 4. The drive device 2 is connected to the machine tool 1, the drive device 2 and the chip removal device 3 are transmission-connected, the chip removal device 3 is connected to the machine tool 1, the chip removal device 3 and the collecting device 4 are connected by pipeline, the collecting device 4 and the machine tool 1 are firmly connected, and the chip removal device 3 sprays arc-shaped liquid to sweep away debris.

[0027] The machine tool 1 is used to provide an installation foundation and processing space. It is controlled by a computer numerical control system to perform high-precision and high-efficiency processing. The drive device 2 is used as the main power source to provide power for various processing techniques. The chip removal device 3 collects the chips generated by the processing to achieve the effect of automatic cleaning of the table. The chip collection device 4 separates the chips to facilitate the recycling of the liquid. When performing CNC processing, the liquid is sprayed outwardly through the chip removal device 3 to form an arc surface, thereby attenuating the speed of the centrifugal chips during the processing to prevent the chips from splashing.

[0028] Furthermore, the machine tool 1 includes a bed 11, a cross module 12 and a lift 14. The bed 11 is provided with a cross module 12, the cross module 12 is spatially arranged, the upper module output end of the cross module 12 is provided with a carrier 13, the lift 14 is tightly connected to the bed 11, the output end of the lift 14 is provided with a machine base 15, and the machine base 15 is connected to the chip removal device 3; The chip removal device 3 includes a guide seat 33, which includes a diverter ring 331 and a base ring 332. The base ring 332 is tightly connected to the machine base 15. The base ring 332 is provided with an annular groove 3321. The upper end of the diverter ring 331 is inserted into the annular groove 3321. The diverter ring 331 is provided with a plurality of centrifugal grooves 3311. The centrifugal grooves 3311 are spirally arranged. The spiral diameter of the centrifugal grooves 3311 gradually decreases from top to bottom. The outlets of the plurality of centrifugal grooves 3311 are combined to form a whole circle. The inlet of the centrifugal groove 3311 is connected to the liquid containing debris.

[0029] The bed 11 adopts a vertical design. By setting a cross module 12, the carrier 13 is driven to move horizontally in the processing space of the bed 11. The cross module 12 adopts a conventional module design and is used to output linear displacement. It is convenient to drive the carrier 13 to move in two intersecting directions, thereby driving the workpiece to move, which is convenient for processing various positions of the workpiece. By setting a lift 14, the lift 14 can be in the form of a screw nut, or a chain transmission structure, so that its output end drives the base 15 to move vertically. The flow is diverted by the guide seat 33. The base ring 332 is fixed on the machine base 15 and can move with the machine base 15. The ring groove 3321 is provided on the base ring 332. The diverter ring 331 is installed. The diverter ring 331 is provided with a plurality of spirally arranged centrifugal grooves 3311. The inlet of the centrifugal groove 3311 is connected to the liquid containing debris. When the impurity-containing liquid spirals downward along the centrifugal groove 3311, due to the large density of impurity particles, the liquid flows along the outer layer of the centrifugal groove 3311 under the action of centrifugal force. The liquid flows along the inner layer of the centrifugal groove 3311 and passes through the spiral diameter from The decreasing arrangement from top to bottom makes the centrifugal force on the impurity particles gradually increase as the centrifugal groove 3311 moves downward, and finally they are ejected along the end of the circle to form a water curtain. The formed water curtain is arranged along the circumference of the driving device 2. The debris generated in the processing process is tilted and scattered circumferentially due to the centrifugal force. The water in the inner layer impacts the debris through the water curtain, causing the speed of the debris to decay. The density of the impurity-containing water in the outer layer is higher, making it impossible for the debris after the speed decays to break through the outer layer of the water curtain, and the debris is moved downward by the water curtain to clean the table.

[0030] Furthermore, the chip removal device 3 also includes a separation component 31 and a booster pump 32. Drainage grooves 111 are respectively provided on both sides of the bed 11. A screening chamber 112 is provided at the end of the drainage groove 111. The separation component 31 is placed in the screening chamber 112. The separation component 31 includes a lifting pump 311 and a lifting seat 312. The inlet of the lifting pump 311 is connected to the drainage groove 111. A guide slope 3121 is provided on the lifting seat 312. The guide slope 3121 is close to the end of the lifting pump 311 as a low end. The output end of the lifting pump 311 faces the guide slope 3121. A plurality of blanking grooves 3122 are provided on the lower side of the guide slope 3121. A accommodating groove 3123 is provided at the end of the guide slope 3121. The inlet of the booster pump 32 is connected to the accommodating groove 3123, the outlet of the booster pump 32 is connected to the annular groove 3321, and the centrifugal groove 3311 is set to open on one side of the annular groove 3321.

[0031] The water body after the water curtain impacts the debris is collected through the drainage grooves 111 on both sides, and is introduced into the lifting pump 311. The lifting pump 311 is used to pressurize the water body, so that the flow rate of the ejected water body is accelerated, and it is ejected along the diversion slope 3121. When the water body flows upward along the diversion slope 3121, this flow path is defined as the screening stroke. The drop trough 3122 is located in the second half of the screening stroke. When the water body flows along the diversion slope 3121, the friction between the impurities with larger mass and the diversion slope 3121 is greater than that of the water body and small particles. The friction between the granular impurities and the guide slope 3121 causes the large granular impurities to fall into the chute 3122 under the action of gravity when flowing to the chute 3122, while most of the water and small granular impurities will pass over the inlet of the chute 3122 under the action of inertia, enter the subsequent stroke, and finally enter the containing groove 3123 to form a liquid containing impurities. The liquid containing impurities is pumped into the annular groove 3321 by the booster pump 32 and flows to the centrifugal groove 3311, so as to form a water curtain, prevent large granular impurities from entering the stage of forming the water curtain, and reduce the erosion and wear on the table surface.

[0032] Furthermore, the driving device 2 includes a driving motor 21 and a tool 22 . A driving cavity is provided on the machine base 15 . The driving motor 21 is placed in the driving cavity. The output end of the driving motor 21 and the tool 22 are firmly connected.

[0033] The drive motor 21 is fixed by the drive cavity on the machine base 15. The drive motor 21 serves as the main drive source for driving the tool 22 to rotate. The lower end of the drive cavity is opened so that the output end of the drive motor 21 can extend out of the drive cavity for easy tool change.

[0034] Furthermore, the driving device 2 also includes a gear ring 24, and the guide seat 33 also includes a middle gear 333. A knife groove 3312 is provided on the diverter ring 331, and a tooth groove 3313 is provided along the wall of the knife groove 3312. The gear ring 24 is tightly connected to the output end of the driving motor 21, and a middle axis bracket is provided at the upper end of the middle gear 333. The middle gear 333 is connected to the base ring 332 through the middle axis bracket. The gear ring 24 is meshed with the tooth surface of the tooth groove 3313 through the middle gear 333, and the diverter ring 331 is rotatably connected to the annular groove 3321.

[0035] A gear ring 24 is provided at the output end of the driving motor 21. When the workpiece is processed by the tool 22, the gear ring 24 is driven to rotate at the same time. The middle gear 333 is installed on the base ring 332 through the middle axis bracket. The middle gear 333 and the middle axis bracket are rotatably connected. When the gear ring 24 and the middle gear 333 are meshed, the meshing transmission of the middle gear 333 and the tooth groove 3313 is driven to rotate the diverter ring 331. The rotation speed of the diverter ring 331 is reduced through the two-stage transmission. During the rotation of the diverter ring 331, the impurity liquid in the centrifugal groove 3311 is driven to be discharged, and it is centrifuged outward at an angle, so as to form a cone-like water curtain, thereby improving the cleaning effect of the processing debris.

[0036] Furthermore, the spiral direction of the centrifugal groove 3311 is the same as the rotation direction of the diverter ring 331 .

[0037] By rotating in the same direction, the impurity-containing liquid is centrifuged outward when flowing out of the centrifugal groove 3311, thereby expanding the range of the water curtain and avoiding impact on the workpiece to affect the cleaning quality.

[0038] As an optimization, the collecting device 4 includes a collecting box 41, which is fastened to the bed 11, and a collecting trough 411 is provided on the collecting box 41. The separation assembly 31 also includes a chip discharge pipe 313, the inlet of the chip discharge pipe 313 is connected to the material dropping trough 3122, and the outlet of the chip discharge pipe 313 faces the collecting trough 411. By providing the collecting box 41, when the water body passes over the material dropping trough 3122, part of the water body enters the chip discharge pipe 313 from the material dropping trough 3122 along with the large particles of debris, and is sent into the collecting trough 411 through the chip discharge pipe 313, so as to facilitate collection.

[0039] As an optimization, a water collecting tank 41 is provided on the collection box 41, and the upper end of the water collecting tank 412 is connected to the collection tank 411, and a screen 42 is provided at the connection between the water collecting tank 412 and the collection tank 411. Through the double-cavity setting of the collection box 41, after the water containing large particles of debris enters the water collecting tank 412, the water falls into the water collecting tank 412 through the screen 42 under the action of gravity, and the large particles of debris cannot pass through the screen 42, thereby automatically separating the large particles of debris.

[0040] As an optimization, the drive device 2 further includes a tool changer 23, and the tool changer 23 is firmly connected to the bed 11. By providing the tool changer 23, the tool changer 23 can be driven by a motor to rotate the required tool to the bottom, so as to facilitate automatic tool change.

[0041] Working principle of the present invention: the inlet of the centrifugal groove 3311 is connected to the liquid containing debris. When the impurity-containing liquid spirals downward along the centrifugal groove 3311, due to the large density of the impurity particles, it flows along the outer layer of the centrifugal groove 3311 under the action of centrifugal force, and the liquid flows along the inner layer of the centrifugal groove 3311. The spiral diameter is arranged to decrease from top to bottom, so that the centrifugal force exerted on the impurity particles during the downward process of the centrifugal groove 3311 gradually increases, and finally sprays out along the end that forms a whole circle to form a water curtain. The formed water curtain is arranged along the circumference of the driving device 2. The debris generated in the processing process is tilted and sprinkled circumferentially under the action of the centrifugal force. The water body in the inner layer impacts the debris through the water curtain, so that the speed of the debris is attenuated. The density of the impurity-containing water body in the outer layer is relatively high, so that the debris after the speed is attenuated cannot break through the outer layer of the water curtain, and is moved downward by the water curtain to perform tabletop operation. Cleaning; when the water flows upward along the guide slope 3121, this flow path is defined as the screening stroke, and the chute 3122 is located in the second half of the screening stroke. When the water flows along the guide slope 3121, the friction between the impurities with larger mass and the guide slope 3121 is greater than the friction between the water, the small particle impurities and the guide slope 3121, so that the large particle impurities fall into the chute 3122 under the action of gravity when flowing to the chute 3122, while most of the water and the small particle impurities will pass over the inlet of the chute 3122 under the action of inertia, enter the subsequent stroke, and finally enter the containing groove 3123 to form a liquid containing impurities. The liquid containing impurities is pumped into the annular groove 3321 by the booster pump 32 and flows to the centrifugal groove 3311, so as to form a water curtain, prevent large particle impurities from entering the stage of forming the water curtain, and reduce the erosion and wear of the table surface.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
