Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically a CNC machining center with a table cleaning function. Background Technology

[0002] CNC machining centers typically refer to precision machining using computer numerical control technology, including CNC lathes, CNC milling machines, and CNC boring machines.

[0003] Compared to traditional machine tools, CNC machine tools, through automatic control, do not rely on the operator's experience, resulting in higher precision in the machined parts. However, CNC machining centers also have certain limitations in use. Due to the low level of human intervention, real-time cleaning is not possible, which can cause debris generated during machining to accumulate on the table, affecting the positioning and machining accuracy to some extent.

[0004] In addition, during CNC machining, liquid is generally used to cool the cutting tools and workpieces to prevent the temperature from getting too high and affecting the machining accuracy. This also causes some debris to adhere to the table surface through the liquid, making cleaning inconvenient. Summary of the Invention

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

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A CNC machining center includes a machine tool, a drive unit, a chip removal device, and a collection device. The drive unit is connected to the machine tool, the drive unit and the chip removal device are connected by a transmission, the chip removal device is connected to the machine tool, the chip removal device and the collection device are connected by pipes, the collection device and the machine tool are fastened together, and the chip removal device sprays an arc-shaped liquid to blow away the chips.

[0008] The machine tool provides the installation foundation and processing space. It is controlled by a computer numerical control system to perform high-precision and high-efficiency machining. The drive unit serves as the main power source, providing power for various machining processes. The chip removal device collects the chips generated during machining, achieving automatic cleaning of the worktable. The chip collection device separates the chips, facilitating the recycling of the liquid. During CNC machining, the chip removal device sprays liquid outward to form an arc-shaped surface, thereby attenuating the speed of centrifugal chips during machining and preventing chip splashing.

[0009] Furthermore, the machine tool includes a bed, a cross module, and a lift. The cross module is provided on the bed and is arranged in a spatial manner. The upper module output end of the cross module is provided with a platform. The lift and the bed are fastened together. The output end of the lift is provided with a machine base and is connected to a chip removal device.

[0010] The chip removal device includes a flow guide seat, which includes a flow divider ring and a base ring. The base ring is fastened to the machine base. The base ring has an annular groove. The upper end of the flow divider ring is inserted into the annular groove. The flow divider ring has several centrifugal channels arranged in a spiral. The diameter of the centrifugal channels gradually decreases from top to bottom. The outlets of several centrifugal channels form a complete circle. The inlet of the centrifugal channels is connected to the liquid containing debris.

[0011] The machine bed adopts a vertical design. By setting up a cross module, the table can be moved horizontally within the machining space of the machine bed. The cross module adopts a conventional module design for outputting linear displacement. The two intersecting directions facilitate the movement of the table, thereby moving the workpiece and facilitating the machining of various parts of the workpiece. By setting up a lifting mechanism, which can be in the form of a lead screw and nut or a chain drive structure, its output end can drive the machine base to move vertically. The flow is diverted by a guide seat, and the base ring is fixed on the machine base and can move with the machine base. A ring groove is provided on the base ring for installing the diverting ring. Several spirally arranged centrifugal tanks are set on the diverting ring. The inlet of the centrifugal tank is connected to a liquid containing debris. As this impurity-laden liquid spirals downwards along the centrifugal tank, due to the higher density of the impurity particles, it flows along the outer layer of the centrifugal tank under the action of centrifugal force. The liquid flows along the inner layer of the centrifugal tank. The spiral diameter decreases from top to bottom, causing the centrifugal force on the impurity particles to gradually increase as they move downwards. Finally, they are ejected along the end of the spiral, forming a water curtain. The water curtain is set circumferentially along the drive device. The debris generated during processing is tilted and thrown circumferentially under the action of centrifugal force. The water curtain causes the inner layer of water to impact the debris, causing the debris velocity to decrease. The outer layer of impurity-laden water has a higher density, preventing the degraded debris from breaking through the outer layer of the water curtain. Instead, the debris is carried downwards by the water curtain for table cleaning.

[0012] Furthermore, the chip removal device also includes a separation component and a booster pump. A flow channel is provided on both sides of the bed, with a screening chamber at the end of each channel. The separation component is placed inside the screening chamber. The separation component includes a lifting pump and a lifting seat. The inlet of the lifting pump is connected to the flow channel. A guide slope is provided on the lifting seat, with the end of the guide slope near the lifting pump being the lower end. The output end of the lifting pump faces the guide slope. Several material drop troughs are provided on the lower side of the guide slope. A receiving trough is provided at the end of the guide slope. The inlet of the booster pump is connected to the receiving trough, and the outlet of the booster pump is connected to the annular groove. The centrifugal trough is opened towards the annular groove.

[0013] Water collected from the impact debris by the water curtain is channeled through diversion channels on both sides and directed into a booster pump. The booster pump pressurizes the water, increasing its velocity and directing it along the guide slope. As the water flows upward along the guide slope, this flow path is defined as the screening stroke. The discharge chute is located in the latter half of the screening stroke. When the water flows along the guide slope, the friction between larger impurities and the guide slope is greater than the friction between the water, smaller impurities, and the guide slope. This causes larger impurities to fall into the discharge chute under gravity, while most of the water and smaller impurities will pass the discharge chute inlet due to inertia and enter the subsequent stroke, eventually entering the receiving tank to form a mixed liquid. The booster pump pumps this mixed liquid into the annular tank and then into the centrifugal tank, facilitating the formation of a water curtain and preventing larger impurities from entering the water curtain formation stage, thus reducing erosion and wear on the platform.

[0014] Furthermore, the drive device includes a drive motor and a cutting tool. The machine base is provided with a drive cavity, the drive motor is placed inside the drive cavity, and the output end of the drive motor is fastened to the cutting tool.

[0015] The drive motor is fixed in 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 open so that the output end of the drive motor can extend out of the drive cavity, which facilitates tool changing.

[0016] Furthermore, the drive unit also includes a gear ring, the guide seat also includes a middle gear, the flow divider ring is provided with a through groove, and a tooth groove is provided along the wall of the through groove. The gear ring and the output end of the drive motor are fastened together. The upper end of the middle gear is provided with a central shaft support. The middle gear is connected to the base ring through the central shaft support. The gear ring meshes with the tooth surface of the tooth groove through the middle gear. The flow divider ring and the ring groove are rotatably connected.

[0017] A gear ring is installed at the output end of the drive motor. When the workpiece is processed by the tool, the gear ring is driven to rotate. The middle gear is mounted on the base ring through the central shaft bracket. The middle gear and the central shaft bracket are rotatably connected. When the gear ring and the middle gear mesh, the middle gear and the tooth groove mesh to drive the flow divider ring to rotate. Through the two-stage transmission, the speed of the flow divider ring is reduced. During the rotation of the flow divider ring, when the liquid containing impurities in the centrifugal tank is driven outward at an angle, it is centrifuged to form a cone-shaped water curtain, which improves the cleaning effect of processing debris.

[0018] Furthermore, the spiral direction of the centrifugal tank is the same as the rotation direction of the diversion ring.

[0019] By rotating in the same direction, the liquid containing impurities flows outwards from the centrifuge tank, expanding the range of the water curtain and preventing it from impacting the workpiece and affecting the cleaning quality.

[0020] As an optimization, the collection device includes a collection box, which is securely connected to the bed. The collection box is equipped with a collection trough. The separation component also includes a chip removal pipe, the inlet of which is connected to the discharge chute, and the outlet of which faces the collection trough. By setting up the collection box, when water passes over the discharge chute, some of the water, along with large particles of debris, enters the chip removal pipe from the discharge chute and is then sent into the collection trough through the chip removal pipe for easy collection.

[0021] As an optimization, the collection tank is equipped with a water collection trough, the upper end of which is connected to the collection tank. A screen is installed at the connection between the water collection trough and the collection tank. With the dual-chamber design of the collection tank, water containing large particles of debris enters the water collection trough. Under the action of gravity, the water falls through the screen into the collection tank, while the large particles of debris cannot pass through the screen, thus automatically separating the large particles of debris.

[0022] As an optimization, the drive unit also includes a tool changer, which is securely connected to the bed. By incorporating the tool changer, which can be driven by a motor, the required tool can be rotated downwards for automatic tool changing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The centrifuge tank inlet is connected to a liquid containing debris. As this impurity-laden liquid spirals downwards along the centrifuge tank, due to the higher density of the impurity particles, it flows along the outer layer of the centrifuge tank under the action of centrifugal force, while the liquid flows along the inner layer of the centrifuge tank. By setting the spiral diameter to decrease from top to bottom, the centrifugal force on the impurity particles gradually increases as the centrifuge tank spirals downwards, and finally, it is sprayed out along the end of the spiral, forming a water curtain. The water curtain is set around the circumference of the driving device. The debris generated during the processing is tilted and thrown around the circumference under the action of centrifugal force. The water in the inner layer impacts the debris, causing the debris velocity to decrease. The outer layer of impurity-laden water has a higher density, so the debris, after its velocity decreases, cannot break through the outer layer of the water curtain. The water is swept downwards by the water curtain to clean the platform. When the water flows upwards along the guide slope, this flow path is defined as the screening stroke. The discharge chute is located in the latter half of the screening stroke. When the water flows along the guide slope, the friction between the larger impurities and the guide slope is greater than the friction between the water, small particles, and the guide slope. This causes the large particles to fall into the discharge chute under gravity when they flow to it. Most of the water and small particles will pass the discharge chute inlet under inertia and enter the subsequent stroke, eventually entering the receiving tank to form a liquid containing impurities. The liquid containing impurities is pumped into the annular tank by the booster pump and flows to the centrifugal tank to facilitate the formation of a water curtain. This prevents large particles from entering the water curtain formation stage and reduces erosion and wear on the platform. Attached Figure Description

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.

[0033] Example: Figures 1-7 As shown, the present invention provides a CNC machining center technical solution with a table cleaning function.

[0034] The CNC machining center includes a machine tool 1, a drive unit 2, a chip removal device 3, and a collection device 4. The drive unit 2 is connected to the machine tool 1, the drive unit 2 and the chip removal device 3 are connected by a transmission, the chip removal device 3 is connected to the machine tool 1, the chip removal device 3 and the collection device 4 are connected by a pipeline, the collection device 4 and the machine tool 1 are fastened together, and the chip removal device 3 sprays arc-shaped liquid to blow away the chips.

[0035] Machine tool 1 provides the installation foundation and processing space. It is controlled by a computer numerical control system to perform high-precision and high-efficiency machining. Drive device 2 serves as the main power source to provide power for various machining processes. Chip removal device 3 collects the chips generated during machining to achieve automatic cleaning of the table. Chip collection device 4 separates the chips to facilitate liquid recycling. During CNC machining, liquid is sprayed outward through chip removal device 3 to form an arc-shaped surface, thereby attenuating the speed of centrifugal chips during machining and preventing chip splashing.

[0036] Furthermore, the machine tool 1 includes a bed 11, a cross module 12, and a lift 14. The cross module 12 is provided on the bed 11 and is arranged in a spatial manner. The upper module output end of the cross module 12 is provided with a platform 13. The lift 14 is fastened to the bed 11. The output end of the lift 14 is provided with a base 15 and is connected to the chip removal device 3.

[0037] The chip removal device 3 includes a flow guide seat 33, which includes a flow divider ring 331 and a base ring 332. The base ring 332 is fastened to the base 15. The base ring 332 is provided with an annular groove 3321. The upper end of the flow divider ring 331 is inserted into the annular groove 3321. The flow divider ring 331 is provided with a plurality of centrifugal channels 3311. The centrifugal channels 3311 are spirally arranged, and the spiral diameter of the centrifugal channels 3311 gradually decreases from top to bottom. The outlets of the plurality of centrifugal channels 3311 are enclosed to form a complete circle, and the inlet of the centrifugal channels 3311 is connected to the liquid containing debris.

[0038] The machine bed 11 adopts a vertical design. By setting a cross module 12, the table 13 is driven to move horizontally within the machining space of the machine bed 11. The cross module 12 adopts a conventional module design and is used to output linear displacement. By crossing two directions, it is easy to drive the table 13 to move, thereby driving the workpiece to move and facilitating the machining of various positions of the workpiece. By setting a lifting mechanism 14, which can be in the form of a lead screw and nut or a chain drive structure, its output end drives the machine base 15 to move vertically. The flow is diverted by the guide seat 33. The base ring 332 is fixed on the base 15 and can move with the base 15. A ring groove 3321 is provided on the base ring 3321 for mounting the diverting ring 331. Several spirally arranged centrifugal channels 3311 are provided on the diverting ring 331. The inlet of the centrifugal channel 3311 is connected to the liquid containing debris. As this impurity-laden liquid spirals downwards along the centrifugal channel 3311, due to the higher density of the impurity particles, it flows along the outer layer of the centrifugal channel 3311 under the action of centrifugal force, while the liquid flows along the inner layer of the centrifugal channel 3311. The liquid then flows through the spiral diameter from... The centrifugal force on impurity particles gradually increases as they move downwards in the centrifugal tank 3311, eventually being ejected along the end of the enclosed circle to form a water curtain. The water curtain is set along the circumference of the drive device 2. The debris generated during the processing is tilted and thrown circumferentially by the centrifugal force. The water curtain causes the inner layer of water to impact the debris, causing the debris velocity to decrease. The outer layer of water containing impurities has a higher density, so the debris with decreased velocity cannot break through the outer layer of the water curtain and is carried downwards by the water curtain for table cleaning.

[0039] Furthermore, the chip removal device 3 also includes a separation component 31 and a booster pump 32. The bed body 11 is provided with a flow channel 111 on both sides. The end of the flow channel 111 is provided with a screening chamber 112. 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 flow channel 111. The lifting seat 312 is provided with a guide slope 3121. The end of the guide slope 3121 near the lifting pump 311 is the low end. The output end of the lifting pump 311 faces the guide slope 3121. Several material drop troughs 3122 are provided on the lower side of the guide slope 3121. The end of the guide slope 3121 is provided with a receiving groove 3123. The inlet of the booster pump 32 is connected to the receiving groove 3123. The outlet of the booster pump 32 is connected to the annular groove 3321. The centrifugal groove 3311 is opened on the side facing the annular groove 3321.

[0040] The water after the water curtain impact debris is collected by the diversion channels 111 on both sides and guided into the lift pump 311. The lift pump 311 pressurizes the water, increasing the flow velocity of the sprayed water and spraying it along the guide slope 3121. When the water flows upward along the guide slope 3121, this flow path is defined as the screening stroke. The discharge chute 3122 is located in the latter half of the screening stroke. When the water flows along the guide slope 3121, the friction between larger impurities and the guide slope 3121 is greater than that between the water and small particles. The friction between particulate impurities and the guide slope 3121 causes large particulate impurities to fall into the discharge trough 3122 under the action of gravity when they flow to the discharge trough 3122. Most of the water and small particulate impurities will pass the inlet of the discharge trough 3122 under the action of inertia and enter the subsequent process, and eventually enter the receiving tank 3123 to form a liquid containing impurities. The liquid containing impurities is pumped into the annular tank 3321 by the booster pump 32 and flows to the centrifugal tank 3311 to facilitate the formation of a water curtain, prevent large particulate impurities from entering the stage of forming the water curtain, and reduce the erosion and wear on the platform.

[0041] Furthermore, the drive device 2 includes a drive motor 21 and a cutting tool 22. The base 15 is provided with a drive cavity, the drive motor 21 is placed in the drive cavity, and the output end of the drive motor 21 is fastened to the cutting tool 22.

[0042] The drive motor 21 is fixed by the drive cavity on the base 15. The drive motor 21 serves as the main drive source to drive the tool 22 to rotate. The lower end of the drive cavity is open so that the output end of the drive motor 21 can extend out of the drive cavity, which facilitates tool changing.

[0043] Furthermore, the drive device 2 also includes a gear ring 24, the guide seat 33 also includes a middle gear 333, the flow divider ring 331 is provided with a through groove 3312, and a tooth groove 3313 is provided along the wall of the through groove 3312. The gear ring 24 is fastened to the output end of the drive motor 21. The upper end of the middle gear 333 is provided with a central shaft support. The middle gear 333 is connected to the base ring 332 through the central shaft support. The gear ring 24 meshes with the tooth surfaces of the middle gear 333 and the tooth groove 3313. The flow divider ring 331 and the ring groove 3321 are rotatably connected.

[0044] A gear ring 24 is provided at the output end of the drive motor 21. When the workpiece is processed by the tool 22, the gear ring 24 is driven to rotate. The intermediate gear 333 is mounted on the base ring 332 through the intermediate shaft bracket. The intermediate gear 333 and the intermediate shaft bracket are rotatably connected. When the gear ring 24 and the intermediate gear 333 mesh, the intermediate gear 333 and the tooth groove 3313 mesh and drive the flow divider ring 331 to rotate. Through the two-stage transmission, the speed of the flow divider ring 331 is reduced. During the rotation of the flow divider ring 331, when the liquid containing impurities in the centrifugal tank 3311 is driven outward at an incline, which facilitates the formation of a cone-shaped water curtain and improves the cleaning effect of processing debris.

[0045] Furthermore, the spiral direction of the centrifugal tank 3311 is the same as the rotation direction of the diversion ring 331.

[0046] By rotating in the same direction, the liquid containing impurities flows outwards from the centrifugal tank 3311, expanding the range of the water curtain and preventing it from impacting the workpiece and affecting the cleaning quality.

[0047] As an optimization, the collection device 4 includes a collection box 41, which is fastened to the bed 11. The collection box 41 is provided with a collection trough 411. The separation component 31 also includes a chip removal pipe 313, the inlet of which is connected to the discharge chute 3122, and the outlet of which faces the collection trough 411. By setting up the collection box 41, when water passes over the discharge chute 3122, some of the water, along with large particles of debris, enters the chip removal pipe 313 from the discharge chute 3122 and is then sent into the collection trough 411 through the chip removal pipe 313, facilitating collection.

[0048] As an optimization, the collection tank 41 is equipped with a water collection trough 412, the upper end of which is connected to the collection tank 411. A screen 42 is provided at the connection between the water collection trough 412 and the collection tank 411. With the dual-chamber configuration of the collection tank 41, water containing large particles enters the water collection trough 412. Under the action of gravity, the water falls into the water collection trough 412 through the screen 42, and the large particles cannot pass through the screen 42, thus automatically separating the large particles.

[0049] As an optimization, the drive unit 2 also includes a tool changer 23, which is securely connected to the bed 11. By setting the tool changer 23, it can be driven by a motor to rotate the required tool downwards, facilitating automatic tool changing.

[0050] The working principle of this invention: The inlet of the centrifuge tank 3311 is connected to a liquid containing debris. As this impurity-laden liquid spirals downwards along the centrifuge tank 3311, due to the higher density of the impurity particles, it flows along the outer layer of the centrifuge tank 3311 under the action of centrifugal force, while the liquid flows along the inner layer of the centrifuge tank 3311. The spiral diameter decreases from top to bottom, causing the centrifugal force on the impurity particles to gradually increase as the centrifuge tank 3311 descends. Finally, the impurity particles are ejected along the end of the spiral, forming a water curtain. This water curtain is arranged circumferentially around the drive device 2. The debris generated during processing is thrown circumferentially by centrifugal force. The water curtain causes the inner layer of water to impact the debris, reducing its velocity. The outer layer of impurity-laden water has a higher density, preventing the degraded debris from breaking through the outer layer of the water curtain. Instead, the debris is carried downwards by the water curtain, forming a platform. Cleaning; When the water flows upward along the guide slope 3121, this flow path is defined as the screening stroke. The discharge chute 3122 is located in the latter half of the screening stroke. When the water flows along the guide slope 3121, the friction between the larger impurities and the guide slope 3121 is greater than the friction between the water, small particles and the guide slope 3121. This causes the large particles to fall into the discharge chute 3122 under the action of gravity when they flow to the discharge chute 3122. Most of the water and small particles will pass the inlet of the discharge chute 3122 under the action of inertia and enter the subsequent stroke, and finally enter the receiving tank 3123, forming a liquid containing impurities. The liquid containing impurities is pumped into the ring tank 3321 by the booster pump 32 and flows to the centrifugal tank 3311 to facilitate the formation of a water curtain, prevent large particles from entering the stage of forming the water curtain, and reduce the erosion and wear on the platform.
