Description

Technical Field

[0001] The present invention relates to the technical field of CNC machining, and particularly relates to a CNC machining device for industrial production. Background Art

[0002] CNC machining is computer numerical control precision machining, which controls the feed speed of the machining tool and the spindle speed, as well as functions such as tool changers and coolants. CNC machining can produce parts with complex shapes that cannot be completed by manual machining.

[0003] Currently, when machining large workpieces with deep cavities, the continuous machining of the tool in the deep cavity will simultaneously use cutting fluid for flushing. The cutting fluid contains mineral oil and various chemical substances, which have adverse effects on the human skin, respiratory system, eyes and nervous system. The cutting fluid is subjected to the excitation impact of the fixed and rotating units in the machine tool system during machining, and will be atomized in large quantities. The atomized cutting fluid will remain in the deep cavity of the large workpiece, making it difficult for the atomized cutting fluid in the deep cavity of the workpiece to disperse quickly after machining, and it is difficult to shorten the usage time of the workshop equipment. There are certain safety hazards for operators. Moreover, when the workpiece is machined to the edge position, due to the clamping and limiting of the workpiece edge, the internal stress generated by cutting cannot be released, and local micro stress deformation is likely to occur after machining, affecting the machining size of the mold. Therefore, a CNC machining device for industrial production is proposed. Summary of the Invention

[0035] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example, refer to Figures 1 to 11 , a CNC machining device for industrial production, including an outer cover 1 and a material feeding seat 2 for placing a to-be-machined blank 3. A plurality of right-angle fixing seats 5 are fixedly connected to the top end of the material feeding seat 2. Two threaded holes with opposite spiral directions are provided on the vertical side wall of the right-angle fixing seat 5. The inner side walls of the two threaded holes are both threadedly connected with threaded push rods 9. A regulating tooth assembly is arranged on the outer side wall of one end of the threaded push rod 9. The other end of the threaded push rod 9 is connected with a plurality of energy-absorbing buffer telescopic rods 11 through a limiting pressure plate 10, and the end of the energy-absorbing buffer telescopic rod 11 is connected with a contact pressure plate 12;

[0037] Furthermore, an installation seat 4 is fixedly connected to the bottom end of the material feeding seat 2, the top end of the installation seat 4 is fixedly connected to the bottom end of the outer cover 1, the other end of the threaded push rod 9 is rotatably connected to the outer side surface of the limiting pressure plate 10, the inner side surface of the limiting pressure plate 10 is fixedly connected to the end of the contact pressure plate 12 through the energy-absorbing buffer telescopic rod 11. The regulating tooth assembly is composed of a driving gear 7 and two driven tooth rings 8. An installation groove is provided on the vertical side wall of the right-angle fixing seat 5, a regulating motor 6 is fixedly connected to the inner side wall of the installation groove, the output end of the regulating motor 6 is fixedly connected to the end of the driving gear 7 through a rotating shaft, the driving gear 7 is respectively engaged with the driven tooth rings 8 on both sides, the inner side wall of the driven tooth ring 8 is connected to the outer side wall of one end of the threaded push rod 9 through a keyway structure, and the driven tooth ring 8 is rotatably connected to the vertical side wall of the right-angle fixing seat 5 through a fixing ring;

[0038] It should be noted that: the blank plate 3 to be processed is placed between multiple right-angle fixing seats 5. Subsequently, the regulating motor 6 on the right-angle fixing seat 5 is started. The regulating motor 6 drives the driving gear 7 to rotate forward through the rotating shaft. The rotation of the driving gear 7 will drive the driven tooth rings 8 engaged on both sides to rotate synchronously. Furthermore, the driven tooth rings 8 drive the threaded push rods 9 to rotate and move in the threaded holes. Since the internal thread directions of the two threaded holes are opposite, the two threaded push rods 9 rotating in opposite directions push the limit pressing plate 10 synchronously, so that multiple contact pressing plates 12 are pressed against the edge of the blank plate 3 to achieve fixed limit, as Figure 7 shown. In the pressed state at this time, the contact pressing plate 12 abuts against the fixed end of the energy-absorbing buffer telescopic rod 11 to achieve rigid pressing of the blank plate 3 and ensure stable clamping of the blank plate 3. Subsequently, the feeding of the material feeding seat 2 and the cutting mechanism 14 is synchronously controlled by the compiled programming information. The compiled processing programming information will also control the regulating motors 6 on each part during the processing. This is the prior art and will not be elaborated here. When the part to be cut is at the edge position on one side of the blank plate 3, the regulating motor 6 at this edge position is controlled by the processing program to drive the driving gear 7 to rotate reversely by a small angle. Then the reverse rotation of the driving gear 7 will drive the two threaded push rods 9 through the two driven tooth rings 8 to rotate, thereby driving the limit pressing plate 10 to move outward, increasing the distance between the limit pressing plate 10 and the edge of the blank plate 3. Under the action of the energy-absorbing buffer telescopic rod 11, the contact pressing plate 12 still presses against the edge position of the blank plate 3;

[0039] Based on the above advantages: in this way, the energy-absorbing buffer telescopic rod 11 can absorb the vibration during the cutting process of the edge of the blank plate 3, so that the stress of the edge processing of the blank plate 3 can be released to a certain extent, preventing the deformation or cracking of the workpiece caused by the stress during the processing of the thin-walled part at the edge, and ensuring the accuracy of the processing size and the processing safety of the workpiece;

[0040] It should be especially noted that: during the edge cutting process, the adjustable energy-absorbing buffer telescopic rod 11 only absorbs the vibration during the edge cutting process of the blank plate 3, and the energy-absorbing buffer telescopic rods 11 at other edge positions are still in the fully pressed state to ensure the stable clamping of the blank plate 3.

[0041] The inner end face of the outer cover 1 is connected with a cutting mechanism 14 through a feeding hydraulic cylinder 13. Two receiving half-rings 15 are arranged on the outer side wall above the cutting mechanism 14. One end of the outer side wall of the receiving half-ring 15 is connected with a docking column 17 through a limit collar 16. A limit ring groove is opened on the end face of the limit collar 16, and a limiting component for limiting the docking column 17 is connected to the inner side wall of the limit ring groove. The other end of the outer side wall of the receiving half-ring 15 is fixedly connected with a docking stepped sleeve 20 through a fixing plate, and a plurality of pressure-limiting components are connected to the inner side wall of the docking stepped sleeve 20;

[0042] Furthermore, a plurality of rubber arc pressing plates 24 are fixedly connected to the inner side wall of the receiving semi-ring 15. One end of the outer side wall of the receiving semi-ring 15 is fixedly connected to the end of the limiting sleeve 16. The inner side wall of the limiting sleeve 16 is slidably connected to the outer side wall of the docking column 17. The limiting component consists of a rotating plate 18 and two limiting push columns 19. The end of the rotating plate 18 is rotatably connected to one end of the docking column 17. The end of the rotating plate 18 is fixedly connected to the ends of the two limiting push columns 19. Two through holes adapted to the limiting push columns 19 are formed in the limiting ring groove of the limiting sleeve 16. The pressing and limiting component consists of a plurality of limiting telescopic rods 21 and a plurality of limiting beads 22. A plurality of limiting grooves adapted to the limiting beads 22 are formed in the outer side wall of the other end of the docking column 17. Transition sliding grooves from deep to shallow are formed in the side walls of the limiting grooves. The inner side wall of the docking stepped sleeve 20 is fixedly connected to the end of the limiting telescopic rod 21. An energy storage spring member 23 is fixedly connected to the inner end surface of the docking stepped sleeve 20;

[0043] It should be noted that: before cutting processing, the docking column 17 on one receiving semi-ring 15 is docked with the docking stepped sleeve 20 on the other receiving semi-ring 15. After the docking column 17 is inserted into the docking stepped sleeve 20, it will press the limiting beads 22 on the limiting telescopic rod 21, causing the limiting telescopic rod 21 to contract. After the limiting beads 22 are docked with the limiting grooves on the outer side wall of the docking column 17, the limiting of the docking column 17 is achieved. At the same time, the limiting push columns 19 on the rotating plate 18 will also be pressed tightly on the limiting ring groove of the limiting sleeve 16. At this time, the two receiving semi-rings 15 are docked. A plurality of rubber arc pressing plates 24 are used to press tightly on the upper annular outer side wall of the cutting mechanism 14. When it is necessary to replace and clean the receiving semi-ring 15, the rotating plate 18 is rotated to drive the limiting push column 19 to the position of the through hole, and then the rotating plate 18 is continuously pressed to make the limiting push column 19 enter the through hole. The docking column 17 will also be inserted and pressed tightly on the energy storage spring member 23, and the limiting beads 22 will slide out through the transition sliding grooves from deep to shallow on the side walls of the limiting grooves. At this time, the pressing force on the rotating plate 18 is removed, so that the docking column 17 instantly pops out under the elastic force of the energy storage spring member 23, realizing the disassembly and separation of the two receiving semi-rings 15;

[0044] The benefits based on the above are as follows: The insertion and separation between the docking column 17 and the docking stepped sleeve 20 can be used to quickly combine and split the two receiving semi-rings 15 in the narrow space of the outer cover 1, resulting in high cleaning and replacement efficiency, and also avoiding affecting the perpendicularity of the cutting mechanism 14 through a strong fastening method;

[0045] A receiving cavity is formed in the receiving semi-ring 15. A plurality of suction holes communicating with the receiving cavity are formed at the bottom end of the receiving semi-ring 15. The bottom end of the suction hole is fixedly connected with a suction component, and the top end of the suction hole is connected with an anti-overflow inverted hopper 27;

[0046] Further, a protective mounting cover 25 is fixedly connected to the outer side wall of the receiving semi-ring 15. A micro air pump 26 is installed in the protective mounting cover 25. The micro air pump 26 is in communication with the receiving cavity of the receiving semi-ring 15. The suction assembly is composed of a suction inclined pipe 28 and a suction hopper 29. The bottom of the receiving semi-ring 15 is fixedly connected to the top end of the suction inclined pipe 28. The bottom end of the suction inclined pipe 28 is fixedly connected to the upper end of the suction hopper 29. The suction inclined pipe 28 communicates with the bottom end of the anti-overflow inverted hopper 27 through a suction hole in the receiving semi-ring 15. There is a gap between the top end of the anti-overflow inverted hopper 27 and the inner end face above the receiving cavity of the receiving semi-ring 15. A valve port is provided on the end face of the receiving semi-ring 15;

[0047] It should be noted that during cutting processing, the cutting fluid continuously flushes the processing part. When the cutting fluid atomizes during the impact process of deep cavity cutting processing, due to the air extraction by the micro air pump 26 in the protective mounting cover 25 in advance, the receiving cavity in the receiving semi-ring 15 is continuously in a negative pressure state. Then the suction hopper 29 will pass the atomized cutting fluid into the anti-overflow inverted hopper 27 through the suction inclined pipe 28. When the gas with atomized cutting fluid passes through the top end of the anti-overflow inverted hopper 27, the through hole becomes narrower and the gas flow rate increases, making the gas inhaled into the receiving semi-ring 15 tend to cool down and then gradually liquefy, facilitating the gradually storage of the inhaled atomized cutting fluid in a liquid form. During the interval between each cutting processing, the micro air pump 26 is used to keep the receiving cavity in the receiving semi-ring 15 in a continuous negative pressure to suck the atomized cutting fluid remaining in the deep cavity of the workpiece;

[0048] Based on the above advantages: The negative pressure state of the receiving cavity in the receiving semi-ring 15 can be used to suck the atomized cutting fluid in the deep cavity of the workpiece, so that the atomized cutting fluid after workpiece processing dissipates faster, shortening the interval downtime of the workshop equipment and ensuring the safety of the operator's working environment;

[0049] When the present invention is in use, the blank 3 to be processed is placed between a plurality of right-angle fixing seats 5. Subsequently, the regulating motor 6 on the right-angle fixing seat 5 is started. The regulating motor 6 drives the driving gear 7 to rotate forward through the rotating shaft. The rotation of the driving gear 7 will drive the driven tooth rings 8 engaged on both sides to rotate synchronously. Then the driven tooth rings 8 drive the threaded push rods 9 to rotate and move in the threaded holes. Since the internal thread directions of the two threaded holes are opposite, the two threaded push rods 9 rotating in the opposite direction push the limit pressing plate 10 synchronously, so that a plurality of contact pressing plates 12 are pressed tightly on the edge of the blank 3 to achieve fixed limit, as Figure 7As shown, in the pressing state at this time, the contact pressing plate 12 abuts against the fixed end of the energy-absorbing buffer telescopic rod 11 to achieve rigid pressing of the blank plate 3, ensuring stable clamping of the blank plate 3. Subsequently, the feeding of the material feeding seat 2 and the cutting mechanism 14 is synchronously controlled using the compiled programming information. The compiled machining programming information also controls the regulating motors 6 at various positions during the machining process. This is the prior art and will not be elaborated here. When the part to be machined is at the edge position on one side of the blank plate 3, the regulating motor 6 at this edge position is controlled by the machining programming to drive the driving gear 7 to reverse-rotate by a small angle. Then, the reverse rotation of the driving gear 7 drives the two threaded push rods 9 to rotate through the two driven toothed rings 8, thereby driving the limit pressing plate 10 to move outwards, increasing the distance between the limit pressing plate 10 and the edge of the blank plate 3. Under the action of the energy-absorbing buffer telescopic rod 11, the contact pressing plate 12 still presses tightly against the edge position of the blank plate 3. The energy-absorbing buffer telescopic rod 11 absorbs the vibration during the cutting process of the edge of the blank plate 3, enabling a certain release of the stress generated during the machining of the edge of the blank plate 3, preventing deformation or cracking of the workpiece caused by the stress during the machining of the thin-walled part at the edge, and ensuring the machining accuracy and safety of the workpiece dimensions;

[0050] Before cutting, the docking column 17 on one receiving half-ring 15 is docked with the docking stepped sleeve 20 on the other receiving half-ring 15. After the docking column 17 is inserted into the docking stepped sleeve 20, it presses the limit beads 22 on the limit telescopic rod 21, causing the limit telescopic rod 21 to contract. After the limit beads 22 are docked with the limit grooves on the outer sidewall of the docking column 17, the docking column 17 is limited. At the same time, the clamping push column 19 on the rotating plate 18 also presses tightly against the limit ring groove of the limit clamping sleeve 16. At this time, the two receiving half-rings 15 are docked. Multiple rubber arc pressing plates 24 are used to press tightly against the upper annular outer sidewall of the cutting mechanism 14. When it is necessary to replace and clean the receiving half-ring 15, the rotating plate 18 is rotated to drive the clamping push column 19 to the perforation position, and then the rotating plate 18 is continuously pressed to make the clamping push column 19 enter the perforation. The docking column 17 will also be inserted and pressed tightly against the energy storage spring member 23. The limit beads 22 will slide out through the gradually deepening and then shallowing transition chute on the sidewall of the limit groove. At this time, the pressing force on the rotating plate 18 is removed, causing the docking column 17 to instantly pop out under the elastic force of the energy storage spring member 23, realizing the disassembly and separation of the two receiving half-rings 15. In this way, the insertion and separation between the docking column 17 and the docking stepped sleeve 20 can be used to quickly combine and disassemble the two receiving half-rings 15 in the narrow space of the outer cover 1, resulting in high cleaning and replacement efficiency and avoiding affecting the perpendicularity of the cutting mechanism 14 through a strong fastening method;

[0051] During the cutting process, the cutting fluid continuously flushes the machining area. When the cutting fluid atomizes during the impact process of deep cavity cutting, due to the prior air extraction by the micro air pump 26 inside the protective mounting cover 25, the storage cavity inside the storage half-ring 15 remains in a negative pressure state continuously. Then, the suction hopper 29 will pass the atomized cutting fluid through the suction inclined pipe 28 into the anti-overflow inverted hopper 27. When the gas with atomized cutting fluid passes through the top of the anti-overflow inverted hopper 27, the through-hole narrows, and the gas flow rate increases, making the gas inhaled into the storage half-ring 15 tend to cool down and then gradually liquefy, facilitating the gradual storage of the inhaled atomized cutting fluid in a liquid state. During the interval between each cutting process, the micro air pump 26 is used to keep the storage cavity inside the storage half-ring 15 in a continuous negative pressure to suck the atomized cutting fluid remaining in the deep cavity of the workpiece. In this way, the negative pressure state of the storage cavity inside the storage half-ring 15 can be used to suck the atomized cutting fluid in the deep cavity of the workpiece, enabling the atomized cutting fluid after workpiece machining to disperse faster, shortening the interval downtime of the workshop equipment, and ensuring the safety of the operator's working environment.
