Description

Technical Field

[0001] This application relates to the technical field of CNC machining equipment, and in particular to a vertical double-column five-axis linkage high-speed machining center. Background Technology

[0002] Vertical twin-column five-axis linkage high-speed machining centers are core equipment for machining complex curved surface parts, high-precision molds, and aerospace structural components. With the continuous improvement of requirements for processing efficiency, positioning accuracy, and automation levels in the high-end equipment manufacturing industry, traditional vertical machining centers can no longer meet the needs of heavy-duty high-speed machining and stable operation under complex working conditions. The industry's demand for technological upgrades to high-performance vertical twin-column five-axis linkage high-speed machining centers is increasingly urgent. Existing vertical twin-column five-axis linkage high-speed machining centers are mostly equipped with a single power source driving the cradle, a cleaning structure, and an external cutting fluid device for cooling and supplying fluid to the machined workpiece. However, the collection and treatment processes for cutting fluid and waste residue are relatively independent. In actual operation, such equipment is prone to problems such as poor chip removal in the machining area and low cutting fluid recycling rate.

[0003] Patent (CN 112846945 A) discloses a spatial angle CNC double-sided machining center, comprising: a base, a worktable fixedly connected to the middle of the base, a fixture connected to the worktable for clamping the workpiece, platforms connected to the base on both sides of the worktable, the platforms being symmetrically arranged about the worktable, and a machining device connected to the platform. The platform drives the machining device to move horizontally and adjusts the machining angle between the machining device and the workpiece. The reasonable arrangement of the fixture, platform, machining device, and tool magazine enables the invention to have flexible tool position and angle adjustment, high machining accuracy, and high machining flexibility. The advantages of this patent include the ability to simultaneously process two planes of a workpiece; the chip conveyor effectively separates the cutting fluid from the machining chips during the collection process and collects them into a chip collection cart, facilitating chip recycling and reducing cutting fluid costs. While the patent enables simultaneous processing of both sides of a workpiece and the separation and recycling of cutting fluid and machining chips, it only achieves basic separation and recycling of the cutting fluid and chips, without realizing a closed-loop supply of cutting fluid. Furthermore, it cannot effectively address the cleaning of dead zones in the cradle unit or the coordinated control of waste collection and cutting fluid supply.

[0004] Regarding the aforementioned technologies, the inventors believe that there are shortcomings such as the difficulty in effectively cleaning up waste residue in the working parts and dead corners, which leads to long-term accumulation and affects the working accuracy of the equipment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a vertical double-column five-axis linkage high-speed machining center.

[0006] This application provides a vertical double-column five-axis linkage high-speed machining center, which adopts the following technical solution: A vertical dual-column five-axis linkage high-speed machining center includes a bed, with a first column and a second column fixedly mounted on both sides of the bed. A milling unit is mounted at one end of the bed, and the milling unit is slidably connected to the top of the first column and the second column. A cradle unit is rotatably mounted on the first column and the second column, and the cradle unit is located at the other end of the bed. The bed has a discharge port located below the cradle unit, and a material collection unit is mounted at the discharge port. The material collection unit includes a material collection trough and a first flexible hose, one end of the first flexible hose communicating with the bottom of the material collection trough, and the other end of the first flexible hose communicating with the cradle unit.

[0007] By adopting the above technical solution, a first column and a second column are respectively set on both sides of the machine bed, and the milling unit is slidably connected to the top of the two columns to form a double-column symmetrical support structure. This enhances the vibration resistance and overall rigidity of the milling unit during heavy-duty machining or high-speed cutting, effectively reducing machine tool deformation during machining. The milling unit is set at one end of the machine bed, and the cradle unit is rotatably set at the other end through the first and second columns. The cradle unit, as the core positioning mechanism, can realize multi-directional flipping and posture adjustment of the workpiece. Combined with the multi-axis movement of the milling unit, it can complete all or most of the machining processes of complex curved surface parts in one go. A material collection unit is set at the machine bed discharge port, and the bottom of the material collection tank is connected to the cradle unit through the first hose. The material collection unit efficiently collects the cutting waste and cutting fluid generated during machining, preventing the accumulation of waste chips from affecting the rotation accuracy of the cradle unit. At the same time, the collected cutting fluid can be returned to the cradle unit through the first hose for cleaning of dead corners, realizing the recycling of cutting fluid. In addition, it also ensures the centralized treatment of waste chips and waste fluid, avoiding environmental pollution at the machining site and improving the environmental performance and ease of operation and maintenance of the equipment.

[0008] Preferably, the cradle unit includes a rotating frame, a rotating shaft, and a worktable; the two ends of the rotating frame are respectively rotatably mounted on a first column and a second column, a first motor is mounted in the middle of the rotating frame, the rotating shaft passes through the rotating frame and is rotatably connected to the rotating frame, the first motor is used to drive the rotating shaft to rotate, and the worktable is fixedly mounted on one end of the rotating shaft; a second motor is mounted on the first column, and the second motor provides power for the rotation of the rotating frame.

[0009] By adopting the above technical solution, the cradle unit drives the rotating shaft of the first motor to rotate the worktable, and at the same time uses the second motor to drive the rotating frame to rotate around the axis of the first and second columns. The two ends of the rotating frame are rotatably connected to the first and second columns, and the worktable can be indexed and rotated with the rotating shaft. Therefore, the workpiece can be processed in one go with multiple angles and multiple curved surfaces.

[0010] Preferably, the workbench is provided with multiple sets of mounting slots, the interior of the workbench is a hollow cavity, the sidewalls of the mounting slots are provided with multiple sets of water outlet holes, and the water outlet holes communicate with the interior of the workbench; the rotating shaft is provided with a water inlet channel, one end of the water inlet channel in the rotating shaft is connected to the interior of the workbench; the other end of the rotating shaft is provided with a rotating interface, and the other end of the water inlet channel in the rotating shaft is connected to the other end of the first hose through the rotating interface.

[0011] By adopting the above technical solution, the inside of the worktable is a hollow cavity, and multiple sets of water outlet holes communicating with the cavity are opened on the side wall of the mounting slot. The cutting fluid entering the water inlet channel through the rotating interface can be directly pumped into the inner cavity of the worktable. The cutting fluid collected by the material collection unit can be directly sprayed from the water outlet holes onto the cutting area of ​​the tool and the workpiece. This not only provides a coolant source for processing, but also realizes the self-cleaning of the workstation itself. The high-pressure liquid flow continuously flushes the inside of the worktable and the dead corners of the mounting slot, which can promptly remove the fine iron filings and debris generated during processing, prevent the waste chips from getting stuck or accumulating and affecting the workpiece clamping reference, and ensure the positioning stability of the cradle unit under long-term high-speed operation.

[0012] Preferably, a rotating sleeve is fitted onto one end of the rotating shaft, and the rotating sleeve is rotatably connected to the rotating shaft; multiple sets of scrapers are arranged circumferentially on the rotating sleeve; driving ports are provided on both sides of the bottom of the worktable, one end of the driving port is arranged at an angle, and the other end of the driving port is connected to the interior of the worktable.

[0013] By adopting the above technical solution, the cutting fluid enters the water inlet channel inside the rotating shaft through the rotating interface and is finally injected into the hollow cavity of the worktable; it is sprayed out at high speed from the water outlet and the drive ports opened on both sides of the bottom of the worktable; the drive ports are arranged at an angle, and the sprayed liquid flow will form a directional hydraulic jet; the liquid flow directly impacts and acts on the scraper arranged circumferentially on the rotating sleeve, driving the scraper to rotate around the axis of the rotating sleeve; under the combined action of liquid thrust and its own inertia, the scraper continuously scrapes the bottom and corners of the worktable, thoroughly scraping away impurities, which are then discharged with the liquid flow.

[0014] Preferably, the collection trough is provided with a partition, which divides the collection trough into a collection area and a liquid injection area. Sliding channels are provided at both ends of the collection trough, with the sliding channels located in the collection area. A separation component is slidably disposed at the sliding channel. A driving component is provided inside the liquid injection area. Multiple sets of water inlets are provided on one side of the partition, and the collection area communicates with the liquid injection area through these water inlets. A reset channel is provided on one side of the collection trough, located in the liquid injection area. A reset component is slidably disposed at the reset channel. Corrugated protective covers are provided on both the sliding channel and the reset channel. The liquid injection area is connected to one end of the first flexible hose.

[0015] By adopting the above technical solution, the partition divides the inside of the collection tank into a collection area and a liquid injection area, and a separation component is set in the collection area. After the mixed waste liquid generated during processing falls into the collection area, the waste residue is effectively intercepted by the separation component, while the cutting fluid permeates through the separation component and the water inlet hole on the partition to the liquid injection area. The separation component in the collection area moves with the change of the weight of the accumulated waste residue. When the weight of the waste residue reaches the preset value, the separation component moves down to trigger the start of the drive component. The drive component pressurizes the cutting fluid in the liquid injection area and delivers it to the cradle unit through the first hose. Corrugated protective covers are set at both the sliding channel and the reset channel. The corrugated protective covers expand and contract synchronously with the movement of the separation component and the reset component, forming a flexible sealing barrier, which effectively prevents high-pressure cutting fluid from leaking out from the sliding gap, ensuring the cleanliness and safety of the equipment operating environment, and solving the technical pain point of sealing moving parts.

[0016] Preferably, the separation assembly includes a separation plate and two sets of return springs; the two ends of the separation plate are slidably disposed on sliding grooves at both ends of the collection trough; the end of the separation plate passes through a corrugated protective cover in the sliding groove and is disposed outside the collection trough, and the separation plate is fixedly connected to the corrugated protective cover in the sliding groove; the two sets of return springs are respectively disposed at both ends of the separation plate, one end of the return spring is fixedly disposed on the separation plate, and the other end of the return spring is fixedly disposed on the collection trough; the separation plate has multiple sets of drainage holes, and the separation plate has a holeless part, the position of which is directly opposite to the multiple sets of water inlet holes of the partition plate.

[0017] By adopting the above technical solution, the separation plate is slidably set on the sliding channel of the collection area, and multiple sets of drainage holes are opened on the plate surface. After the mixed waste liquid generated during processing falls into the collection area, the waste residue is effectively intercepted by the separation plate, while the cutting fluid can permeate to the partition through the drainage holes. This completes the initial separation of solid and liquid, prevents large particles of waste residue from entering the injection area, and avoids the risk of blockage in subsequent pipelines or pumps. The non-perforated part of the separation plate is positioned directly opposite the multiple sets of water inlets on the partition. When the separation plate is triggered by the weight of the waste residue and moves downward, the non-perforated part covers the water inlets, blocking the direct connection between the collection area and the injection area, forcing the cutting fluid in the injection area to be output only through the first hose, thus achieving the guidance and sealing control of the fluid flow. The return spring provides initial elastic support and limit for the separation plate, ensuring its stability in the initial position. On the other hand, when the waste residue in the collection area is cleaned, the return spring can drive the separation plate to quickly return to its initial position.

[0018] Preferably, the driving assembly includes a piston block and a driving spring; the piston block is slidably disposed in the injection area; one end of the driving spring is disposed at one end of the piston block, and the other end of the driving spring is fixedly disposed in the collection trough.

[0019] By adopting the above technical solution, when the drive component is unlocked, the drive spring quickly releases potential energy, pushing the piston block to slide at high speed in the injection zone, thereby delivering the cutting fluid in the injection zone to the cradle unit through the first hose; after completing one fluid supply, the piston block is reset under the drive of the reset component.

[0020] Preferably, an unlocking structure is provided on the other side of the partition, the unlocking structure including a driving cavity, a driving block, an unlocking cavity, an unlocking block, and a locking spring; the driving cavity is disposed inside the partition, one end of the driving block is slidably disposed in the driving cavity, and the other end of the driving block is disposed in the material collection area; the locking spring is sleeved on the driving block, one end of the locking spring is fixed to the partition, and the other end of the locking spring is fixed to the other end of the driving block; the unlocking cavity is disposed inside the partition, one end of the unlocking block is slidably disposed in the unlocking cavity, and the other end of the unlocking block is disposed in the liquid injection area, and one side of the other end of the unlocking block is provided as a locking slope; the unlocking cavity is in communication with the driving cavity.

[0021] By adopting the above technical solution, one end of the drive block is set in the collection area, directly bearing the downward pressure generated by the weight of the waste residue on the separation plate; when the separation plate moves down and presses the drive block, the drive block slides along the drive cavity and pushes the unlocking block to move along the unlocking cavity, thereby releasing the lock on the piston block; the end of the unlocking block is provided with a locking slope to ensure that the piston block is smoothly reset under the action of the reset component; the locking spring sleeved on the unlocking structure, when the waste residue on the separation plate is cleaned, the separation plate moves up under the action of the reset spring, the drive block loses pressure and resets under the action of the locking spring.

[0022] Preferably, the reset assembly includes a reset sleeve, a sliding rod, a return spring, and a drive rod; the reset sleeve is slidably disposed in the injection area; the sliding rod is slidably disposed in the reset channel, one end of the sliding rod is fixedly connected to the reset sleeve, and the other end of the sliding rod passes through the corrugated protective cover in the reset channel and is disposed outside the collection trough, the sliding rod being fixedly connected to the corrugated protective cover in the reset channel; both ends of the drive rod are fixedly connected to both ends of the separation plate, the drive rod is arranged at an angle, and the drive rod abuts against the sliding rod; the return spring is disposed in the injection area, one end of the return spring is fixed to the reset sleeve, and the other end of the return spring is fixedly disposed in the collection trough.

[0023] By adopting the above technical solution, one end of the return spring in the reset assembly is fixed to the reset sleeve, and the other end is fixed to the collection trough, providing a continuous elastic restoring force for the reset sleeve. When the waste residue on the separation plate is removed, the separation plate resets upward under the elastic force of the reset spring, driving the drive rod to move upward synchronously. The drive rod abuts against the sliding rod, pushing the sliding rod and the reset sleeve back to their original positions, thereby driving the piston block to reset and relock. The drive rod is arranged at an angle and abuts against the sliding rod. When the separation plate moves up and down, the drive rod converts the vertical linear motion of the separation plate into the horizontal linear motion of the sliding rod along the reset channel through the inclined abutment relationship. The corrugated protective cover can extend and retract synchronously with the reciprocating sliding of the sliding rod, forming a flexible sealing barrier, effectively preventing the high-pressure cutting fluid in the injection area from leaking out from the sliding gap of the reset channel.

[0024] Preferably, the milling unit includes a mounting frame, a first slide, a second slide, a ram, and a machining spindle; the mounting frame is fixedly mounted on one end of the machine bed; the first slide is slidably mounted on the mounting frame in the middle; the two sides of the first slide are slidably connected to a first column and a second column, respectively; the second slide is slidably mounted on the first slide; the ram is slidably mounted longitudinally on the second slide, and the machining spindle is mounted on the ram.

[0025] By adopting the above technical solution, the middle part of the first slide is slidably mounted on the mounting frame, while its two sides are slidably connected to the top of the first column and the second column, respectively. When the first slide moves along the length of the bed, it is always supported by the two columns. This enhances the vibration resistance and overall rigidity of the milling unit during heavy-duty machining or high-speed cutting, effectively reducing machine tool deformation during machining. The first slide moves away from or towards the cradle unit along the mounting frame and the first and second columns. The second slide moves between the first and second columns along the first slide. The ram provides longitudinal up and down feed along the second slide. Combined with the dual-axis rotation of the cradle unit, a five-axis linkage system is perfectly formed. This ensures that the machining spindle can be positioned quickly and accurately in three-dimensional space, making it suitable for efficient one-time machining of complex curved surface parts, and greatly improving the machining freedom and applicability of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The worktable has a hollow cavity inside, and multiple sets of water outlet holes connected to the cavity are opened on the side wall of the mounting slot. The cutting fluid entering the water inlet channel through the rotating interface can be directly pumped into the inner cavity of the worktable. The cutting fluid collected by the collection unit can be directly sprayed from the water outlet holes onto the cutting area of ​​the tool and the workpiece. This not only provides a coolant source for machining, but also achieves self-cleaning of the workstation itself. The high-pressure liquid flow continuously flushes the inside of the worktable and the dead corners of the mounting slot, which can promptly remove fine iron filings and debris generated during machining, prevent waste chips from getting stuck or accumulating and affecting the workpiece clamping reference, and ensure the positioning stability of the cradle unit under long-term high-speed operation.

[0027] 2. A partition divides the inside of the collection tank into a collection area and a liquid injection area, and a separation component is installed in the collection area. After the mixed waste liquid generated during processing falls into the collection area, the waste residue is effectively intercepted by the separation component, while the cutting fluid permeates through the separation component and the water inlet hole on the partition to the liquid injection area. The separation component in the collection area moves with the change in the weight of the accumulated waste residue. When the weight of the waste residue reaches a preset value, the separation component moves down to trigger the start of the drive component. The drive component pressurizes the cutting fluid in the liquid injection area and delivers it to the cradle unit through the first hose. Corrugated protective covers are installed at both the sliding channel and the reset channel. The corrugated protective covers expand and contract synchronously with the movement of the separation component and the reset component, forming a flexible sealing barrier. This effectively prevents high-pressure cutting fluid from leaking out from the sliding gap, ensuring the cleanliness and safety of the equipment operating environment and solving the technical pain point of sealing moving parts.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a vertical, double-column, five-axis linkage high-speed machining center. (Refer to...) Figure 1 and Figure 2The system includes a bed 1, with a first column 11 and a second column 12 fixedly mounted on both sides of the bed 1. A milling unit 6 is mounted at one end of the bed 1, and the milling unit 6 is slidably connected to the top of the first column 11 and the second column 12. A cradle unit 2 is rotatably mounted on the first column 11 and the second column 12, and the cradle unit 2 is located at the other end of the bed 1. The bed 1 has a discharge port 13 located below the cradle unit 2, and a collection unit 3 is mounted at the discharge port 13. The collection unit 3 includes a collection trough 31 and a first flexible hose 32, one end of which is connected to... The bottom of the material collection trough 31 is connected, and the other end of the first flexible hose 32 is connected to the cradle unit 2; the milling unit 6 includes a mounting frame 61, a first slide 62, a second slide 63, a ram 64, and a machining spindle 65; the mounting frame 61 is fixedly mounted on one end of the bed 1; the middle part of the first slide 62 is slidably mounted on the mounting frame 61; the two sides of the first slide 62 are slidably connected to the first column 11 and the second column 12 respectively; the second slide 63 is slidably mounted on the first slide 62; the ram 64 is longitudinally slidably mounted on the second slide 63, and the machining spindle 65 is mounted on the ram 64.

[0037] Reference Figure 1 and Figure 2 The machine bed 1 is an integral support structure. The milling unit 6 located at one end of the machine bed 1 is responsible for performing specific machining operations. The central mounting bracket 61 of the first slide 62 is slidably engaged. The two sides of the first slide 62 are also slidably connected to the first column 11 and the second column 12, respectively, thereby realizing a wide range of reciprocating movement along the length of the machine bed 1. The second slide 63 is mounted on the first slide 62 and can move laterally relative to the first slide 62. The ram 64 is assembled in the second slide 63 and drives the machining spindle 65 to perform longitudinal up and down feed movements. Through the coordinated linkage of multiple axes, complex milling operations are performed on the workpiece. The workpiece to be processed is set at the cradle unit 2, which is rotatably mounted on the first column 11 and the second column 12, located at the other end of the bed 1. During processing, the cradle unit 2 drives the workpiece to rotate or index to achieve multi-angle processing. At the same time, the material collection unit 3 works in conjunction at the discharge port 13 to collect the cutting waste and cutting fluid generated during processing. The waste is collected in the material collection tank 31, and the cutting fluid is pumped back to the cradle unit 2 through the first hose 32. The high-pressure liquid flow is used to wash and clean the non-waste impurities remaining on the cradle unit 2 to ensure positioning accuracy.

[0038] Reference Figure 2 , Figure 3 and Figure 4The cradle unit 2 includes a rotating frame 21, a rotating shaft 22, and a worktable 23. The two ends of the rotating frame 21 are rotatably mounted on a first column 11 and a second column 12, respectively. A first motor is mounted in the middle of the rotating frame 21. The rotating shaft 22 passes through the rotating frame 21 and is rotatably connected to it. The first motor drives the rotating shaft 22 to rotate. The worktable 23 is fixedly mounted on one end of the rotating shaft 22. A second motor is mounted on the first column 11, providing power for the rotation of the rotating frame 21. The worktable 23 has multiple sets of mounting slots 231. The interior of the worktable 23 is a hollow cavity. The side walls of the mounting slots 231 have multiple sets of water outlet holes 2311. 311 is connected to the workbench 23; a water inlet channel 221 is provided in the rotating shaft 22, one end of the water inlet channel 221 in the rotating shaft 22 is connected to the interior of the workbench 23; a rotating interface 222 is provided at the other end of the rotating shaft 22, the other end of the water inlet channel 221 in the rotating shaft 22 is connected to the other end of the first hose 32 through the rotating interface 222; a rotating sleeve 24 is sleeved on one end of the rotating shaft 22, and the rotating sleeve 24 is rotatably connected to the rotating shaft 22; multiple sets of scrapers 25 are arranged around the rotating sleeve 24; two drive ports 232 are provided at the bottom of the workbench 23, one end of the drive port 232 is arranged at an angle, and the other end of the drive port 232 is connected to the interior of the workbench 23.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The workpiece to be processed is placed in the mounting groove 231 on the upper surface of the worktable 23. During processing, the second motor drives the rotating frame 21 to rotate on the first column 11 and the second column 12, thereby causing the workpiece to achieve spatial rotation and positioning. When processing a specific surface of the workpiece, the first motor starts and drives the rotating shaft 22 to rotate the worktable 23 in an indexing manner, so that the workpiece obtains the required processing angle. During the processing, the material collection unit 3 sends the cutting fluid into the water inlet channel 221 inside the rotating shaft 22 through the rotating interface 222, and then injects it into the hollow part of the worktable 23. Inside the cavity; the cutting fluid is sprayed directly through the water outlet 2311 on the side wall of the mounting slot 231 to cool the workpiece and remove chips from the mounting slot 231; on the other hand, the cutting fluid is sprayed out from the drive ports 232 on both sides of the bottom of the worktable 23; since the drive ports 232 are arranged at an angle, the sprayed liquid not only has a strong scouring force, but also impacts and drives the scraper 25 to rotate around the rotating sleeve 24; under the thrust and rotation of the liquid, the scraper 25 scrapes and pushes the residual waste at the bottom of the worktable 23, thus cleaning the bottom of the worktable 23.

[0040] Reference Figure 2 and Figure 5The collection trough 31 is equipped with a partition 311, which divides the collection trough 31 into a collection area 312 and an injection area 313. Sliding channels 314 are provided at both ends of the collection trough 312. A separation component 33 is slidably installed at the sliding channel 314. A driving component 34 is installed inside the injection area 313. Multiple sets of water inlets 3111 are provided on one side of the partition 311, and the collection area 312 is connected to the injection area 313 through the water inlets 3111. A reset channel 315 is provided on one side of the collection trough 313, located in the injection area 313. A reset component 5 is slidably installed at the reset channel 315. Corrugated protective covers are provided on both the sliding channel 314 and the reset channel 315. The injection area 313 is connected to one end of the first hose 32. The collection trough 31 is divided by the partition 311. The system is divided into a collection zone 312 and an injection zone 313, forming a pre-partition for solid-liquid separation. Waste residue is retained in the separation component 33 in the collection zone 312, while cutting fluid flows through the separation component 33 to the partition 311. The cutting fluid then permeates into the injection zone 313 through multiple sets of water inlets 3111 on the partition 311. When the waste residue collected by the separation component 33 reaches a certain weight, that is, when the separation component 33 slides down to a preset position, the drive component 34 located inside the injection zone 313 is activated, which transports the cutting fluid collected in the injection zone 313 to the cradle unit 2 through the first hose 32, forming a closed-loop circulation. To prevent liquid leakage in the sliding gap between the sliding channel 314 and the reset channel 315, both channels are covered with corrugated protective covers. These protective covers expand and contract synchronously with the movement of the components, forming a sealing barrier and effectively preventing liquid overflow.

[0041] Reference Figure 5 and Figure 6An unlocking structure 4 is provided on the other side of the partition 311. The separation assembly 33 includes a separation plate 331 and two sets of return springs 332. The two ends of the separation plate 331 are slidably disposed on the sliding channels 314 at both ends of the collection trough 31. The end of the separation plate 331 passes through the corrugated protective cover in the sliding channel 314 and is disposed outside the collection trough 31. The separation plate 331 is fixedly connected to the corrugated protective cover in the sliding channel 314. The two sets of return springs 332 are respectively disposed at both ends of the separation plate 331. One end of the return spring 332 is fixedly disposed on the separation plate 331, and the other end of the return spring 332 is fixedly disposed on the collection trough 31. The separation plate 331 has multiple sets of drainage holes 3311 and a holeless part 3312. The position of the holeless part 3312 is directly opposite to the multiple sets of water inlets 3111 of the partition 311. The drive assembly 34 includes a piston block 341 and a drive spring. 342; Piston block 341 is slidably disposed in injection zone 313; One end of drive spring 342 is disposed at one end of piston block 341, and the other end of drive spring 342 is fixedly disposed in collection trough 31; During the downward movement of separation plate 331, the non-perforated part 3312 on separation plate 331 will gradually align and cover the water inlet hole 3111 on partition plate 311, thereby blocking the direct liquid flow channel between collection zone 312 and injection zone 313, forcing the liquid to be unable to flow back; At the same time, the end of separation plate 331 triggers unlocking structure 4, releasing the elastic potential energy of drive spring 342. Under the thrust of drive spring 342, piston block 341 slidably disposed in injection zone 313 moves rapidly. At this time, water inlet hole 3111 is blocked by non-perforated part 3312, and cutting fluid can only be delivered to the cradle unit 2 through the first hose 32 connected to injection zone 313, thereby forming a closed-loop circulation system for processing and cleaning.

[0042] Reference Figure 5 and Figure 6The unlocking structure 4 includes a driving cavity 41, a driving block 42, an unlocking cavity 43, an unlocking block 44, and a locking spring 45. The driving cavity 41 is disposed within the partition 311. One end of the driving block 42 is slidably disposed within the driving cavity 41, and the other end of the driving block 42 is disposed within the collection area 312. The locking spring 45 is sleeved on the driving block 42, with one end of the locking spring 45 fixed to the partition 311 and the other end fixed to the other end of the driving block 42. The unlocking cavity 43 is disposed within the partition 311. One end of the unlocking block 44 is slidably disposed within the unlocking cavity 43, and the other end of the unlocking block 44 is disposed within the injection area. 313, one side of the other end of the unlocking block 44 is set as a locking slope 441; the unlocking cavity 43 is connected to the driving cavity 41; when the separating plate 331 moves down due to the accumulation of waste residue, the separating plate 331 will directly press the driving block 42; the driving block 42 slides into the driving cavity 41 under pressure, driving the unlocking block 44 in the unlocking cavity 43 to retract and unlock the piston block 341; after the waste residue on the separating plate 331 is cleaned, the separating plate 331 is reset by the reset spring 332, the driving block 42 is reset by the locking spring 45, driving the unlocking block 44 in the unlocking cavity 43 to pop out and lock the piston block 341.

[0043] Reference Figure 2 , Figure 5 and Figure 6The reset assembly 5 includes a reset sleeve 51, a sliding rod 52, a return spring 54, and a drive rod 53. The reset sleeve 51 is slidably disposed in the injection area 313. The sliding rod 52 is slidably disposed in the reset channel 315. One end of the sliding rod 52 is fixedly connected to the reset sleeve 51, and the other end of the sliding rod 52 passes through the corrugated protective cover in the reset channel 315 and is disposed outside the collection trough 31. The sliding rod 52 is fixedly connected to the corrugated protective cover in the reset channel 315. Both ends of the drive rod 53 are connected to the separation plate 3. The two ends of 31 are fixedly connected, the drive rod 53 is arranged at an angle, and the drive rod 53 abuts against the sliding rod 52; the return spring 54 is set in the liquid injection area 313, one end of the return spring 54 is fixed on the reset sleeve 51, and the other end of the return spring 54 is fixedly set in the collection trough 31; while the separation plate 331 supports the weight of the waste residue and moves downward, it simultaneously drives the drive rod 53, which is fixedly connected to both ends of the separation plate 331, to move downward together; since the drive rod 53 is arranged at an angle and abuts against the sliding rod 52, when the drive rod 53 is pressed down When the drive rod 53 is moved, the inclined surface of the drive rod 53 will push the sliding rod 52 to slide along the reset groove 315, causing the reset sleeve 51 fixed to the sliding rod 52 to move synchronously in the injection area 313, thereby compressing the return spring 54 and accumulating elastic potential energy; at this time, the displacement of the reset sleeve 51 releases space for the piston block 341 to slide, ensuring that the piston block 341 can be smoothly triggered and push the cutting fluid; after the equipment is stopped and the waste residue on the separation plate 331 is cleaned manually or by an external mechanism, the separation plate 331 will return to its original position. Under the elastic force of the position spring 332, the reset sleeve 51 slides in the opposite direction under the elastic force of the return spring 54, driving the sliding rod 52 to slide along the reset through groove 315 and pushing the piston block 341 back to its original position. As the piston block 341 passes over the unlocking block 44 through the locking ramp 441 and is re-locked under the action of the locking spring 45, the drive assembly 34 is locked again. The entire collection unit 3 returns to its initial state and is ready for the next waste collection and liquid supply cycle.

[0044] The working principle of a vertical double-column five-axis linkage high-speed machining center in this application is as follows: the middle of the first slide 62 is slidably engaged with the mounting frame 61, and both sides are simultaneously slidably connected to the tops of the first column 11 and the second column 12, realizing reciprocating movement along the length of the bed 1; the second slide 63 moves laterally along the first slide 62, and the slide ram 64 drives the machining spindle 65 to perform longitudinal up and down feed, completing complex milling operations through multi-axis coordinated linkage; the workpiece is fixed in the mounting slot 231 of the worktable 23 of the cradle unit 2, and the second motor drives the rotating frame 21 to rotate, realizing the spatial posture flipping of the workpiece; the first motor drives the rotating shaft 22 to drive the worktable 23 to rotate in increments, so that the workpiece... Achieving precise machining angles; during machining, the cutting fluid from the collecting unit 3 enters the water inlet channel 221 of the rotating shaft 22 through the rotating interface 222, and is injected into the hollow cavity of the worktable 23. Part of it is sprayed through the water outlet 2311 on the side wall of the mounting slot 231 to achieve workpiece cooling and chip removal from the mounting slot 231; the other part is sprayed out from the drive ports 232 arranged at an angle on both sides of the bottom of the worktable 23, impacting and driving the scraper 25 on the rotating sleeve 24 to rotate, scraping and pushing the residual waste at the bottom of the worktable 23 to complete the cleaning; the collecting tank 31 is divided into a collecting area 312 and a liquid injection area 313 by the partition 311. The cutting waste and cutting fluid generated during machining fall into the collecting area 312, and the waste is... The separation component 33 intercepts and retains the cutting fluid, which permeates through the drainage hole 3311 of the separation plate 331 to the partition plate 311, and then enters the injection zone 313 through the water inlet 3111. When the separation plate 331 slides down due to the accumulated weight of the waste residue, the non-perforated part 3312 of the separation plate 331 blocks the water inlet 3111, blocking the direct flow of liquid between the collection zone 312 and the injection zone 313. At the same time, the separation plate 331 presses the drive block 42, which slides along the drive cavity 41 and pushes the unlocking block 44 to retract from the unlocking cavity 43 through the inclined surface, releasing the lock on the piston block 341. At this time, the drive spring 342 releases its elastic potential energy, pushing the piston block 341 to move rapidly, injecting the fluid. Cutting fluid in zone 313 is pumped into cradle unit 2 via first hose 32; after waste residue is cleaned, separation plate 331 moves upward and resets under the action of reset spring 332, driving drive rod 53 to move upward; reset sleeve 51 slides in the opposite direction under the action of return spring 54, driving piston block 341 to reset via sliding rod 52, piston block 341 passes over unlocking block 44 to lock inclined surface 441 and re-clamp, completing the reset of collection unit 3, preparing for the next collection and liquid supply cycle; at the same time, corrugated protective cover extends and retracts synchronously with the movement of separation component 33 and sliding rod 52, effectively preventing liquid from leaking out from the gap between sliding channel 314 and reset channel 315, ensuring the stability of equipment operation.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
