Description

Technical Field

[0001] This invention relates to the field of turning and milling machine tool technology, specifically to a high-precision bed-turning and milling composite machining equipment for CNC machine tools. Background Technology

[0002] In the field of precision machinery manufacturing, high-precision CNC machine tools with integrated turning and milling capabilities have become core processing equipment in industries such as aerospace and high-end equipment due to their ability to perform integrated turning and milling of complex parts, significantly improving processing efficiency and part forming accuracy. The structural stability of the machine bed and the operational reliability of its core components directly determine the quality of the final processed products. As the market demands for part machining accuracy and equipment service life continue to increase, the large amount of heat generated during the high-speed rotation of the spindle, as the core power output component of the equipment, has become a key factor restricting machining accuracy.

[0003] In existing technologies, spindle cooling often employs independently powered spray devices or fixed-pipe spray structures. The former requires additional components such as pumps and drive motors, resulting in bulky equipment structures and increased power consumption. The latter is mostly a fixed-point or localized spray mode, with limited coolant coverage, easily causing excessively high local spindle temperatures and uneven heat distribution, leading to spindle thermal deformation. This not only reduces the stability of machining accuracy but also accelerates the wear of core components such as spindle bearings. Simultaneously, mill-turn machining generates a large amount of metal chips. If these chips are not handled effectively and promptly, they will not only scatter in the machining area, affecting workpiece clamping accuracy and surface finish, but may also enter the clearances of moving parts such as guide rails and lead screws, causing component wear. These technical challenges limit the further optimization and application of high-precision bed-based mill-turn machining equipment. Therefore, those skilled in the art propose a high-precision bed-based mill-turn machining equipment for CNC machine tools to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-precision bed-based milling and turning composite machining equipment for CNC machine tools, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision bed-based milling and turning composite machining equipment for CNC machine tools, comprising a machine body, an electric guide rail one mounted on one side of the top of the machine body, a storage box slidably connected to the electric guide rail one via an electric slider, an electric guide rail two mounted on the outside of the storage box, a movable frame slidably connected to the electric guide rail two, a drive motor one fixedly mounted on the top of the movable frame, a spindle fixedly connected to the output end of the drive motor one, and a synchronous pulley two fixedly connected to the output end of the drive motor one, the synchronous pulley two being connected to a synchronous pulley two via a belt drive. The first synchronous wheel has a cooling assembly connected to its bottom via a drive assembly. The cooling assembly includes a fixed cylinder fixedly mounted on the outside of the movable frame. A rubber piston is slidably connected to the inner side of the fixed cylinder, and a connecting rod is fixedly connected to the outer side of the rubber piston. The outer side of the fixed cylinder is sequentially connected to an installation pipe 1 and an installation pipe 2. The first synchronous wheel is driven to rotate by a drive motor, and the first synchronous wheel is driven to rotate synchronously via a belt drive. The first synchronous wheel drives the rubber piston to reciprocate along the inside of the fixed cylinder via the drive assembly, thereby spraying the coolant in the storage tank onto the outer surface of the spindle through the installation pipe 2 to achieve real-time cooling.

[0006] Through the above technical solution, the positions of the storage box, movable frame and cooling components can be flexibly adjusted by electric guide rail one and electric guide rail two to adapt to different processing scenarios; drive motor one synchronously realizes the spindle processing drive and power supply to the cooling components, eliminating the need for an additional cooling power source and simplifying the equipment structure; the cooling components realize the stable suction and pressurized spraying of coolant through the reciprocating movement of rubber pistons, accurately acting on the outer surface of the spindle, removing the heat generated during processing in real time, avoiding spindle thermal deformation, and ensuring processing accuracy and spindle operation stability.

[0007] Preferably, the drive assembly includes a rotating disk fixedly connected to the outer side of a synchronous pulley, a drive block fixedly connected to the outer eccentric part of the rotating disk, a movable frame slidably connected to the outer side of the rotating disk, a movable plate fixedly connected to the outer side of the movable frame, and the movable plate fixedly connected to the end of the connecting rod away from the rubber piston.

[0008] Through the above technical solution, the rotating disk rotates synchronously with the synchronous wheel, driving the drive block to move eccentrically. This rotational power is converted into the linear reciprocating movement of the moving frame, and then transmitted to the connecting rod via the moving plate. This enables the rubber piston to slide back and forth along the sealed fixed cylinder, providing power support for the stable suction and pressurized delivery of coolant.

[0009] Preferably, a swing rod is rotatably connected to the outer eccentric part of the first synchronous wheel, and a movable plate is rotatably connected to the end of the swing rod away from the first synchronous wheel. An arc-shaped groove is formed on the outer surface of the movable plate, and a connecting block is slidably installed inside the arc-shaped groove. A moving rod is fixedly connected to the outside of the connecting block, and the moving rod is fixedly connected to the bottom end of the second mounting tube. The rotation of the first synchronous wheel drives the swing rod to rotate synchronously, and the traction force of the swing rod drives the movable plate to move back and forth. In turn, the moving rod drives the bottom end of the second mounting tube to move up and down back and forth.

[0010] Through the above technical solution, the rotation of the synchronous wheel drives the swing rod to swing, which in turn drives the movable plate to move back and forth. With the help of the arc groove and the connecting block, the horizontal reciprocating motion is converted into the up and down motion of the moving rod, thereby realizing the reciprocating swing of the bottom end of the mounting tube, expanding the coverage of the coolant spray, and ensuring uniform cooling of the entire spindle.

[0011] Preferably, both the first and second mounting pipes are fixedly equipped with one-way valves, the two one-way valves have opposite conduction directions, and the end of the first mounting pipe away from the fixed cylinder is connected to the inside of the storage tank to realize one-way delivery of coolant.

[0012] The above technical solution utilizes one-way valves with opposite conduction directions in installation pipe one and installation pipe two to achieve one-way delivery of coolant from the storage tank through installation pipe one into the fixed cylinder, and then from the fixed cylinder through installation pipe two. This prevents coolant backflow and ensures stable coolant supply and cooling effect for the cooling components.

[0013] Preferably, a filter screen is slidably installed at the bottom of the machine body via a limiting plate, a reciprocating screw is movably connected to the inner side of the machine body via a bearing, a motor for driving the reciprocating screw to rotate is fixedly installed on the inner side of the machine body, a fixing plate is threaded to the outer side of the reciprocating screw, an electromagnet is fixedly installed on the outer side of the fixing plate, and a collection frame is detachably connected to the outer side of the machine body; the motor drives the reciprocating screw to rotate, causing the fixing plate to move back and forth along the outer surface of the reciprocating screw, and by controlling the energization and de-energization of the electromagnet, the adsorbed iron filings are released into the collection frame.

[0014] The above technical solution provides a sliding mounting base for the filter screen through a limiting plate. The reciprocating screw driven by the motor is rotated, and the rotational power is converted into the linear reciprocating movement of the fixed plate. This allows the electromagnet to cover a wider range of iron filings adsorption. By controlling the on and off state of the electromagnet, the adsorption and release of iron filings are achieved. Finally, the iron filings are collected into a detachable collection frame, achieving automated iron filings cleaning and avoiding the accumulation of iron filings that may affect equipment operation and processing accuracy.

[0015] Preferably, an installation box is installed on the outer side of the machine body, a second drive motor is installed on the inner side of the installation box, a connecting shaft is movably connected to the inner side of the installation box via bearings, a first bevel gear is fixedly connected to both the upper and lower ends of the connecting shaft, an installation seat is fixedly connected to the inner side of the machine body, a movable seat is slidably connected to the inner side of the installation seat, a rotating shaft is movably connected to the outer side of the installation seat via bearings, a sector gear is fixedly connected to one end of the rotating shaft, and rack plates are fixedly connected to both the upper and lower sides of the interior of the movable seat.

[0016] The above technical solution provides stable sliding support for the filter screen through the limiting plate, ensuring the initial filtration effect of the filter screen on the processed iron filings. By using a motor to drive the reciprocating screw to rotate, the rotational power is converted into the linear reciprocating motion of the fixed plate, allowing the electromagnet to cover a wider area for iron filings adsorption. By precisely controlling the electromagnet's energization and de-energization, the filtered iron filings are efficiently collected and fall into a detachable collection frame, realizing automated cleaning and centralized collection of iron filings, avoiding the accumulation of iron filings that affects the equipment's operating accuracy and the cleanliness of the processing environment.

[0017] Preferably, the outer sides of both rack plates are meshed with the outer side of the sector gear, and the outer side of the movable seat is fixedly connected to one side of the filter screen via a connecting strip.

[0018] Through the above technical solution, the rotational power of the sector gear is converted into the linear reciprocating motion of the movable seat by the meshing of two rack plates and sector gears. The reciprocating motion is then transmitted to the filter screen through the connecting bar, causing the filter screen to vibrate at high frequency. This effectively prevents iron filings from accumulating and clogging the filter screen, ensuring the smooth flow of the filter screen's filtration channels and laying the foundation for efficient collection of iron filings.

[0019] Preferably, the output end of the drive motor two and the end of the rotating shaft away from the sector gear are both fixedly connected to bevel gear two, and the two bevel gear two are respectively meshed with the outer side of the bevel gear one at the corresponding position.

[0020] Through the above technical solution, a high-efficiency bevel gear transmission mechanism is constructed by meshing the second bevel gear at the output end of the second drive motor with the first bevel gear at one end of the connecting shaft, and by meshing the second bevel gear at the end of the rotating shaft with the first bevel gear at the other end of the connecting shaft. This enables the reversal and smooth transmission of the rotational power of the second drive motor, driving the rotating shaft to rotate synchronously and providing stable power for the sector gear to drive the filter screen vibration.

[0021] Preferably, a chuck for clamping workpieces is fixedly installed on the top center side of the machine body, and a control panel is fixedly installed on the outside of the mounting box. The control panel is electrically connected to drive motor one, drive motor two, electric guide rail one, electric guide rail two, and electromagnet, respectively, for controlling the coordinated operation of various components of the equipment.

[0022] The above technical solution enables the workpiece to be firmly clamped by the chuck on the top side of the machine body, providing a reliable positioning basis for processing. At the same time, the control panel on the outside of the mounting box is electrically connected to various power and execution components, enabling centralized control and coordinated operation of various functional modules such as processing, cooling, and chip cleaning, ensuring accurate and efficient processing.

[0023] Preferably, the movable frame has an internal slot adapted to the drive block. The drive block is movably embedded in the slot and slides against the inner wall of the slot. The movable frame is driven to reciprocate by the eccentric rotation of the drive block.

[0024] Through the above technical solution, by using the movable groove inside the moving frame that is adapted to the drive block, and the sliding contact design between the drive block and the inner wall of the movable groove, the eccentric rotation of the drive block is converted into the smooth linear reciprocating movement of the moving frame, providing reliable power transmission for the reciprocating motion of the rubber piston in the cooling assembly.

[0025] This invention provides a high-precision bed-based milling and turning composite machining equipment for CNC machine tools. It has the following beneficial effects: 1. This invention utilizes an integrated power transmission architecture of the drive motor and spindle. Through the synchronous linkage of the drive components with the reciprocating pumping action of the rubber piston and the dynamic lifting and lowering motion of the mounting pipe, it achieves stable output and targeted spraying of coolant, forming real-time and efficient thermal control of the spindle. On the other hand, it constructs a dynamic spray field covering the entire spindle, breaking the limitations of traditional fixed-point spraying and ensuring balanced heat distribution in all areas of the spindle. This not only significantly improves the stability and durability of the equipment's processing accuracy but also extends the service life of the spindle's core components through a scientific thermal management mechanism, combining the technical advantages of compact structure and functional synergy.

[0026] 2. This invention indirectly drives the sector gear to rotate via a drive motor, thereby causing the filter screen to vibrate at high frequency. This effectively prevents iron filings from accumulating and clogging the filter screen, ensuring the smooth flow of the filter channel. At the same time, by precisely controlling the energization and de-energization of the electromagnet, the adsorbed iron filings can be efficiently transferred to the collection frame, realizing automated collection and cleaning of iron filings without manual intervention. This not only improves the efficiency of iron filings processing and keeps the processing area clean, but also avoids iron filings residue affecting the accuracy and stability of equipment operation, significantly optimizing the convenience of equipment operation and maintenance and the reliability of processing.

[0029] The technical solutions in 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.

[0030] Please see the appendix Figure 1 - Appendix Figure 10This invention provides a high-precision bed-type milling and turning composite machining equipment for CNC machine tools, including a machine body 1. An electric guide rail 301 is mounted on one side of the top of the machine body 1. A storage box 4 is slidably connected to the electric guide rail 301 via an electric slider. An electric guide rail 302 is mounted on the outside of the storage box 4. A movable frame 303 is slidably connected to the electric guide rail 302. A drive motor 304 is fixedly mounted on the top of the movable frame 303. A spindle 305 is fixedly connected to the output end of the drive motor 304, and a synchronous pulley 803 is also fixedly connected to the output end of the drive motor 304. The synchronous pulley 803 is connected to the synchronous pulley 802 via a belt drive. The bottom of the synchronous pulley 802 is connected to the drive motor 802 via a belt drive. The moving assembly is connected to a cooling assembly. The cooling assembly includes a fixed cylinder 901 fixedly installed on the outside of the movable frame 303. A rubber piston 905 is slidably connected to the inner side of the fixed cylinder 901, and a connecting rod 904 is fixedly connected to the outer side of the rubber piston 905. The outer side of the fixed cylinder 901 is sequentially connected to an installation tube 902 and an installation tube 903. The drive motor 304 drives the synchronous pulley 803 to rotate, and the synchronous pulley 802 rotates synchronously via belt drive. The synchronous pulley 802 drives the rubber piston 905 to reciprocate along the inside of the fixed cylinder 901 through the drive assembly, thereby spraying the coolant in the storage tank 4 onto the outer surface of the main shaft 305 through the installation tube 903 to achieve real-time cooling. One-way valves are fixedly installed inside both the installation tube 902 and the installation tube 903. The two one-way valves have opposite directions of conduction, and the end of the installation tube 902 away from the fixed cylinder 901 is connected to the inside of the storage tank 4 to achieve one-way delivery of coolant.

[0031] Specifically, the machine body 1 serves as the overall installation reference for the equipment. An electric guide rail 301 mounted on one side of its top is used to adjust the horizontal position of the spindle 305. The storage tank 4 is specifically used to store the coolant required for cooling the spindle 305. An electric guide rail 302 on the outside of the storage tank 4 can drive the movable frame 303 for vertical position adjustment. The movable frame 303 provides stable mounting support for the drive motor 304. The drive motor 304, as the core power source, directly drives the spindle 305 to rotate for milling and turning of the workpiece. Simultaneously, it transmits power to the synchronous pulley 802 via the output pulley 803 and a transmission belt. The synchronous pulley 802 then transmits the power through the drive assembly. The coolant is then directed to the cooling assembly. Within the cooling assembly, the fixed cylinder 901 serves as a temporary storage and pressurization chamber for the coolant. The rubber piston 905 inside the cylinder 901 achieves the suction and discharge of the coolant through a sealed reciprocating sliding motion. The connecting rod 904 transmits the reciprocating power of the drive assembly to move the rubber piston 905. The first mounting pipe 902 is responsible for guiding the coolant from the storage tank 4 into the fixed cylinder 901, and the second mounting pipe 903 is responsible for spraying the pressurized coolant onto the outer surface of the spindle 305. The one-way valves inside both pipes work together to ensure unidirectional delivery of the coolant and prevent backflow. Ultimately, through the synergistic effect of the above components, real-time cooling is achieved during the machining process of the spindle 305, ensuring the operational stability and machining accuracy of the spindle 305.

[0032] The drive assembly includes a rotating disk 12 fixedly connected to the outside of the synchronous pulley 802. A drive block 14 is fixedly connected to the outer eccentric part of the rotating disk 12. A movable frame 13 is slidably connected to the outside of the rotating disk 12. A movable plate 15 is fixedly connected to the outside of the movable frame 13. The movable plate 15 is fixedly connected to the end of the connecting rod 904 away from the rubber piston 905.

[0033] Specifically, the drive block 14 at the eccentric position on the outside of the rotating disk 12 moves eccentrically with the rotating disk 12, thereby converting the rotational power into a reciprocating driving force for the moving frame 13; the moving frame 13 slides with the rotating disk 12, converting the eccentric motion of the drive block 14 into its own linear reciprocating motion; the moving plate 15 on the outside of the moving frame 13 serves as a power connection component, synchronously transmitting the reciprocating motion of the moving frame 13 to the connecting rod 904, ultimately driving the rubber piston 905 to slide reciprocally along the inner side of the fixed cylinder 901, thereby realizing the suction and discharge action of the coolant.

[0034] A swing rod 805 is rotatably connected to the outer eccentric part of the first synchronous pulley 802. A movable plate 801 is rotatably connected to the end of the swing rod 805 away from the first synchronous pulley 802. An arc-shaped groove 806 is opened on the outer surface of the movable plate 801. A connecting block 807 is slidably installed inside the arc-shaped groove 806. A moving rod 804 is fixedly connected to the outside of the connecting block 807. The moving rod 804 is fixedly connected to the bottom end of the second mounting tube 903. The rotation of the first synchronous pulley 802 drives the swing rod 805 to rotate synchronously. Under the traction force of the swing rod 805, the movable plate 801 is driven to move back and forth. In turn, the moving rod 804 drives the bottom end of the second mounting tube 903 to move up and down back and forth.

[0035] Specifically, when the synchronous pulley 802 rotates, the swing rod 805 at its external eccentric position swings in a circular motion, converting the rotational power of the synchronous pulley 802 into a reciprocating traction force on the movable plate 801. Under the action of the traction force, the movable plate 801 moves linearly back and forth, and the arc groove 806 on its outer surface provides a sliding guide path for the connecting block 807, so that the connecting block 807 slides along the arc groove 806 while moving with the movable plate 801, thereby converting the horizontal reciprocating motion of the movable plate 801 into the up-and-down reciprocating motion of the moving rod 804. The moving rod 804 transmits this motion to the bottom end of the mounting tube 903, realizing the up-and-down swing of the spray end of the mounting tube 903, thereby expanding the spray coverage of the coolant on the spindle 305 and ensuring uniform cooling of the entire spindle 305.

[0036] A filter screen 601 is slidably installed on the bottom of the body 1 via a limiting plate 603. A reciprocating screw 602 is movably connected to the inner side of the body 1 via a bearing. A motor for driving the reciprocating screw 602 to rotate is fixedly installed on the inner side of the body 1. A fixing plate 604 is threadedly connected to the outer side of the reciprocating screw 602. An electromagnet 605 is fixedly installed on the outer side of the fixing plate 604. A collection frame 24 is detachably connected to the outer side of the body 1. The motor drives the reciprocating screw 602 to rotate, causing the fixing plate 604 to move back and forth along the outer surface of the reciprocating screw 602. By controlling the energization and de-energization of the electromagnet 605, the adsorbed iron filings are released into the collection frame 24.

[0037] Specifically, the limiting plate 603 at the bottom of the machine body 1 provides sliding guidance and limiting support for the filter screen 601, ensuring that the filter screen 601 stably achieves preliminary filtration of iron filings; the reciprocating screw 602 inside the machine body 1 rotates under the drive of a dedicated motor, converting the rotational power of the motor into the linear reciprocating motion of the fixed plate 604, so that the fixed plate 604 drives the electromagnet 605 to cover a wider area for iron filings adsorption; the electromagnet 605 generates magnetic force by being energized to adsorb the iron filings filtered by the filter screen 601, and then the magnetic force is eliminated by de-energizing, so that the adsorbed iron filings fall into the collection frame 24 on the outside of the machine body 1 under the action of gravity, ultimately realizing the automated and efficient collection and centralized processing of iron filings.

[0038] A mounting box 2 is installed on the outer side of the main body 1. A drive motor 10 is installed on the inner side of the mounting box 2. A connecting shaft 19 is movably connected to the inner side of the mounting box 2 via bearings. Both ends of the connecting shaft 19 are fixedly connected to bevel gears 20. A mounting base 16 is fixedly connected to the inner side of the main body 1. A movable seat 5 is slidably connected to the inner side of the mounting base 16. A rotating shaft 18 is movably connected to the outer side of the mounting base 16 via bearings. A sector gear 22 is fixedly connected to one end of the rotating shaft 18. Both the upper and lower sides of the movable seat 5 are fixedly connected to rack plates 23. The outer sides of the two rack plates 23 are meshed with the outer sides of the sector gears 22. The outer side of the movable seat 5 is fixedly connected to one side of the filter screen 601 via a connecting strip 17.

[0039] Specifically, the mounting box 2 on the outside of the body 1 provides a stable installation and protection space for components such as the second drive motor 10 and the connecting shaft 19. The second drive motor 10 outputs rotational power as a power source, which drives the connecting shaft 19 to rotate through the bevel gear transmission mechanism. The connecting shaft 19 realizes the reversal and synchronous transmission of power through the bevel gears 20 at both ends, thereby driving the rotating shaft 18 to rotate. The sector gear 22 at one end of the rotating shaft 18 rotates synchronously with it. Through intermittent meshing with the rack plates 23 on both sides inside the movable seat 5, the rotational power is converted into the linear reciprocating motion of the movable seat 5. The mounting seat 16 on the inside of the body 1 provides precise sliding guidance for the movable seat 5 to ensure its smooth reciprocating motion. The movable seat 5 transmits the reciprocating motion to the filter screen 601 through the connecting strip 17, causing the filter screen 601 to generate high-frequency vibration, effectively preventing the accumulation and clogging of iron filings and ensuring filtration efficiency.

[0040] The output end of the drive motor 210 and the end of the rotating shaft 18 away from the sector gear 22 are both fixedly connected to bevel gear 21. The two bevel gears 21 are respectively meshed with the outer side of the bevel gear 10 at the corresponding position.

[0041] Specifically, the rotational power output by the second drive motor 10 is transmitted to the first bevel gear 20 at the end of the connecting shaft 19 through the second bevel gear 21 at its output end. The power reversal characteristic of the bevel gear meshing is used to realize the transmission direction conversion, driving the connecting shaft 19 to rotate synchronously. The connecting shaft 19 meshes with the second bevel gear 21 at the end of the rotating shaft 18 through the first bevel gear 20 at the other end, smoothly transmitting power to the rotating shaft 18, so that the rotating shaft 18 obtains rotational power that is synchronous with and adapted to the direction of the second drive motor 10, providing stable power support for the subsequent movement of the movable seat 5 driven by the sector gear 22.

[0042] A chuck 7 for clamping workpieces is fixedly installed on the top center side of the machine body 1. A control panel 11 is fixedly installed on the outside of the mounting box 2. The control panel 11 is electrically connected to drive motor 304, drive motor 10, electric guide rail 301, electric guide rail 302, and electromagnet 605, respectively, for controlling the coordinated operation of various components of the equipment. The movable frame 13 has an internal movable groove adapted to the drive block 14. The drive block 14 is movably embedded in the movable groove, and the drive block 14 slides against the inner wall of the movable groove. The eccentric rotation of the drive block 14 drives the movable frame 13 to reciprocate.

[0043] Specifically, the chuck 7 on the top center of the machine body 1 clamps and fixes the workpiece, providing a stable reference positioning for turning and milling, and preventing displacement of the workpiece during processing; the control panel 11 on the outside of the mounting box 2 serves as the centralized control core of the equipment, realizing the start, stop and parameter adjustment of drive motor 1 304, drive motor 2 10, electric guide rail 1 301, electric guide rail 2 302 and electromagnet 605 through electrical connection, ensuring that each component operates in coordination according to processing requirements; the movable groove inside the moving frame 13 is adapted to the drive block 14, and the sliding fit design of the drive block 14 in the movable groove reduces motion friction. When it rotates eccentrically, the rotational motion is converted into linear reciprocating motion of the moving frame 13 by the force of the inner wall of the movable groove, providing a smooth and effective motion form for subsequent power transmission.

[0044] Working principle: First, the workpiece to be processed is placed in the chuck 7 on the top center side of the machine body 1. The chuck 7 is activated via the control panel 11 to clamp the workpiece, completing the positioning and fixing before processing. Then, the drive motor 304 is activated via the control panel 11. The output end of the drive motor 304 directly drives the spindle 305 to rotate at high speed, performing milling and turning operations on the workpiece. At the same time, the output end of the drive motor 304 synchronously drives the synchronous pulley 803 to rotate. The synchronous pulley 803, through belt transmission, pulls the synchronous pulley 802 to rotate at the same speed, thereby triggering the dual linkage action of the cooling system.

[0045] On the cooling system side, the rotation of the synchronous pulley 802 drives the rotating disk 12 fixed on its outer side to rotate synchronously, and the drive block 14 at the eccentric position on the outer side of the rotating disk 12 performs eccentric circular motion accordingly. Since the drive block 14 is movably embedded in the movable groove inside the movable frame 13, and the drive block 14 slides against the inner wall of the movable groove, the eccentrically moving drive block 14 generates a lateral traction force on the movable frame 13, causing the movable frame 13 to perform reciprocating linear motion along the outer surface of the rotating disk 12. The reciprocating movement of the movable frame 13 is transmitted to the connecting rod 904 through the movable plate 15 fixed on its outer side, which in turn drives the rubber piston 905 fixed at the other end of the connecting rod 904 to perform sealed reciprocating sliding along the inner wall of the fixed cylinder 901. When the rubber piston 905 moves away from the fixed cylinder 901, a negative pressure is formed inside the fixed cylinder 901. Under the action of the air pressure difference, the coolant in the storage tank 4 enters the fixed cylinder 901 through the one-way valve inside the first mounting pipe 902. When the rubber piston 905 moves in the opposite direction, the air pressure inside the fixed cylinder 901 increases, and the coolant is squeezed into the second mounting pipe 903. It is then sprayed out from the port nozzle through the one-way valve inside the second mounting pipe 903, thereby achieving real-time cooling of the high-speed rotating spindle 305. At the same time, the rotation of the synchronous pulley 802 will also drive the swing rod 805 at its external eccentric position to swing in a circular motion. The end of the swing rod 805 away from the synchronous pulley 802 pulls the movable plate 801 to move back and forth. The arc groove 806 on the outer surface of the movable plate 801 drives the moving rod 804 to move up and down through the internal sliding connecting block 807. The moving rod 804 is fixedly connected to the bottom end of the mounting tube 903, which ultimately drives the nozzle of the mounting tube 903 to swing up and down along the axis of the main shaft 305, greatly expanding the spray coverage of the coolant and ensuring that the main shaft 305 is heated evenly throughout.

[0046] On one side of the scrap handling system, the independent motors of drive motor 10 and drive reciprocating screw 602 are simultaneously started via control panel 11. The output end of drive motor 10 drives bevel gear 21 at its end to rotate. This bevel gear 21 meshes with bevel gear 20 at one end of connecting shaft 19, causing connecting shaft 19 to rotate and drive bevel gear 20 at the other end to rotate synchronously. Then, through bevel gear 20 meshing with bevel gear 21 at the end of rotating shaft 18, rotating shaft 18 and sector gear 22 at its end are driven to rotate. Since sector gear 22 intermittently meshes with rack plates 23 on the upper and lower sides inside movable seat 5, the rotation of sector gear 22 is converted into high-frequency reciprocating sliding of movable seat 5 along the inner side of mounting base 16. Movable seat 5 drives filter screen 601 to vibrate synchronously at high frequency along limit plate 603 via connecting bar 17, effectively preventing the scrap generated during processing from accumulating and clogging on the surface of filter screen 601, and ensuring the separation efficiency of coolant and scrap. Simultaneously, after the motor driving the reciprocating lead screw 602 starts, it drives the reciprocating lead screw 602 to rotate. The fixed plate 604, which is threadedly connected to the reciprocating lead screw 602, moves smoothly back and forth along the lead screw axis. The electromagnet 605 on the outside of the fixed plate 604 remains energized under the control of the control panel 11, adsorbing iron filings filtered by the filter screen 601 along the way. When the fixed plate 604 moves to the corresponding position of the collection frame 24, the control panel 11 controls the electromagnet 605 to be de-energized, and the adsorbed iron filings fall into the collection frame 24 under the action of gravity, completing the automated collection of iron filings. During the entire processing, the electric guide rail 1 301 can drive the storage box 4 to move horizontally, and the electric guide rail 2 302 can drive the movable frame 303, the spindle 305, and the cooling components to adjust their positions vertically, ensuring that the processing and cooling actions are accurately adapted to the workpiece processing requirements. All components achieve coordinated linkage through the control panel 11, ensuring the efficient and stable operation of the equipment.
