Description

Technical Field

[0001] This invention relates to the field of ultra-thin irregular-shaped workpiece processing technology, and in particular to an ultra-thin irregular-shaped metal sealing fixture and its usage method. Background Technology

[0002] In high-end manufacturing fields such as aerospace, precision hydraulic transmission, and high-end precision instruments, ultra-thin irregular-shaped metal seals serve as core basic sealing elements. Their processing accuracy and forming quality directly determine the sealing performance, operational reliability, and service life of the equipment, placing extremely high demands on the adaptability, precision, and stability of the processing tooling.

[0003] Chinese Patent Publication No. CN116175444A discloses a tooling fixture, including: a base, a limiting component, and a positioning mechanism; the limiting component is disposed on one side of the base; the positioning mechanism includes a positioning component and a locking component, the positioning component and the limiting component are spaced apart, and the positioning component is constructed with a positioning groove.

[0004] The above-mentioned technical solutions have many defects in actual use. For example, the processing of the front and back sides of ultra-thin irregular metal seals requires special fixtures of different specifications. The existing technology lacks an integrated tooling design, which requires multiple processing equipment to operate separately in the processing process. This not only greatly increases the cost of equipment investment and site occupation, but also makes the overall processing process cumbersome and complicated, and tooling changeover takes a long time.

[0005] Furthermore, when machining the front of ultra-thin irregular-shaped metal seals, the tooling clamps lack the effect of limiting and supporting the metal seals, causing the metal seals to vibrate with the tool and affecting the machining quality.

[0006] When machining the reverse side of ultra-thin irregular-shaped metal seals, the metal seals need to be directly embedded in the limiting groove of the tooling. After machining, the metal seals are prone to getting stuck inside the limiting groove due to problems such as chip jamming and surface adhesion. If the part is removed manually from one side, the ultra-thin irregular-shaped metal seals are prone to plastic deformation due to their poor rigidity, which directly leads to the scrapping of the metal seals. In addition, the manual removal operation is cumbersome and reduces the overall processing efficiency.

[0007] When machining the cutting groove on the reverse side of ultra-thin irregular-shaped metal seals, the coolant sprayed from the spray pipe tends to accumulate inside the cutting groove and cannot be discharged in time. This makes it difficult for the subsequent coolant to reach the milling cutting surface, thus failing to form a continuous and effective cooling effect. Furthermore, the heat generated by continuous milling of ultra-thin irregular-shaped metal seals cannot be dissipated quickly, making them prone to thermal deformation. This can lead to problems such as machining dimensional deviations and insufficient sealing surface fit accuracy of the metal seals.

[0008] Metal chips generated during milling will remain inside the cutting groove and on the outer surface of the coolant tank along with the coolant. If not cleaned in time, the chips will interfere with the normal cutting action of the milling cutter, affecting not only the surface and dimensional accuracy of the cutting groove, but also potentially causing chipping and wear of the milling cutter, thus shortening its service life.

[0009] The coolant inlet is designed to be fixed and normally open. However, meaningless negative pressure pumping can cause metal shavings to enter the suction pipe along with the coolant, resulting in shavings accumulating and clogging inside the pipe. This can affect the normal operation of the subsequent pumping function and may also cause local air suction to cause air explosions, resulting in damage to the equipment.

[0010] Furthermore, when the suction pipe continuously draws coolant from the cutting groove through the inlet, metal chips mixed in the coolant are prone to accumulate and block the inlet. This not only causes the inlet to fail, but also causes the coolant in the ultra-thin cutting groove to accumulate continuously and not be discharged, thus affecting the overall operational stability of the fixture device. Summary of the Invention

[0011] The purpose of this invention is to provide a metal sealing fixture, its application in a machine tool, and a method of use, in order to solve the problems mentioned in the background art.

[0012] To achieve the above objectives, the present invention provides the following technical solution: a tooling fixture for an ultra-thin irregularly shaped metal seal, comprising a fixed platform and a rotating platform, wherein a metal seal is disposed inside the rotating platform, and further comprising: The adjustment section, located inside the rotary table, includes a moving part and a support part. When the front side of the metal seal is machined, the support part supports and limits the metal seal. The suction unit, which is symmetrically arranged on the upper side of the rotating table, includes a liquid suction shell. When the reverse side of the metal seal is machined, the liquid suction shell sucks up the residual coolant inside the metal seal and scrapes off the residual chips. The actuating part, which is located inside the suction part, includes a compression plate and a guide plate. When the suction part suctions the coolant remaining in the metal seal, the moving part drives the compression plate and the guide plate to move synchronously.

[0013] Preferably, the fixed platform is fixed in position, and the rotating platform is rotatably connected to the outer surface of the fixed platform. A movable part is provided at the top axis of the fixed platform, and the output end of the movable part is fixedly connected to the top of the liquid extraction shell. A milling cutter and a liquid spraying pipe are provided above the fixed platform and the rotating platform.

[0014] Preferably, the movable component is movably connected between the fixed platform and the rotating platform. The rotating platform has a working cavity on the side above the fixed platform. The support component is movably connected inside the working cavity and is located outside the movable component. The support component has an assembly cavity inside it.

[0015] Preferably, the adjustment part further includes: The limiting component is located in the assembly cavity inside the support component, and its side wall is fixedly connected to the side wall of the moving component. The limiting component moves synchronously with the moving component. The telescopic component is located on the underside of the moving component and is used to drive the moving component to move up and down. The moving component, support component, limit component and telescopic component all rotate synchronously with the rotating table around the fixed table.

[0016] Preferably, a suction pipe is provided above the liquid extraction shell for suctioning the coolant remaining in the cutting groove; the liquid extraction shell is used to scrape off the chips remaining in the cutting groove, and an inlet is provided inside one side of the liquid extraction shell for suctioning the coolant remaining in the cutting groove, and a flow cavity is formed inside the liquid extraction shell.

[0017] Preferably, the actuating part further includes: The connector is slidably connected to the inside of the liquid inlet, with one end connected to the compression plate and the other end connected to the guide plate. The connector moves synchronously with the guide plate and is elastic. The follower plate, which is set on the upper surface of the guide plate and has an inverted "L" shape, is used to drive the guide plate to move. One side of the follower plate is slidably connected to the side wall of the liquid extraction shell. The guide plate is provided with a drainage groove for discharging the chips on the guide plate.

[0018] Preferably, the guide plate is disposed on the outside of the liquid extraction shell and slidably connected to the outer wall of the liquid extraction shell, and is used to scrape off the chips accumulated on the surface of the liquid extraction shell. The compression plate is disposed inside the liquid extraction shell, with the side away from the liquid inlet being an inclined surface, and the side inside the liquid extraction shell away from the liquid inlet being a wedge-shaped surface. The inclined surface and the wedge-shaped surface slide in a wedge-shaped fit. When the moving part drives the guide plate to move up and down reciprocatingly, the compression plate moves synchronously with the guide plate to squeeze the coolant in the flow cavity.

[0019] Preferably, the actuating part further includes: The elastic element is located inside the flow cavity, with one end abutting against the top of the compression plate and the other end fixedly connected to the top of the flow cavity, and is used to drive the compression plate to reset and squeeze the coolant in the flow cavity. The docking holes are evenly distributed inside the compression plate and are used to transport the coolant in the flow chamber. The inner diameter of the docking holes is smaller than the inner diameter of the inlet. When the compression plate moves up and down inside the flow chamber, the coolant inside the flow chamber flows out along the docking holes.

[0020] A fixture for ultra-thin irregular-shaped metal seals and its method of use, wherein the method utilizes the fixture to clamp and fix the metal seal, comprising the following steps: S1. When machining the front of the metal seal, the support is flush with the upper surface of the rotating table, the height of the moving part is higher than the height of the support, and multiple sets of liquid extraction shells press on the top of the metal seal. S2. Prepare for reverse machining of metal seals, move the support down to the maximum distance, and make the height of the moving part higher than the height of the support. S3. When machining the reverse side of the metal seal, the metal seal is cut as the rotary table rotates. The overlapping area of ​​the liquid inlet and the compression plate decreases continuously as the groove depth increases, and the liquid inlet continuously draws in coolant. S4. When the tank depth is greater than the inlet height, the follower plate and the compression plate move downward to the initial position, and the compression plate disengages from blocking the inlet. S5. The moving part periodically drives the compression plate and guide plate to move upward to the maximum distance and then retracts. The guide plate moves upward to scrape off the chips accumulated on the surface of the liquid extraction shell and guides the chips out. The compression plate quickly retracts and compresses the coolant in the flow chamber to rush out from the liquid inlet. S6. After the reverse side is machined, the support is lifted upward to push the metal seal out of the annular cutting groove and remove the metal seal.

[0021] The technical effects and advantages of this invention are as follows: 1. This invention achieves integrated tooling switching for the forward and reverse processing of ultra-thin irregular-shaped metal seals by linking the telescopic parts, moving parts and supporting parts of the adjustment part. It eliminates the need to change multiple sets of fixtures and processing equipment, greatly simplifies the processing steps, reduces equipment investment and manpower and material consumption, improves processing efficiency, and adapts to the needs of industrial batch continuous processing.

[0022] 2. This invention uses the telescopic component to drive the moving component, the limiting component and the supporting component to form a surface contact uniform push on the processed metal seal, and smoothly lift the metal seal from the annular cutting groove, completely avoiding the problem of metal seal jamming, while preventing the plastic deformation of the metal seal caused by manual removal, and effectively improving the product processing yield.

[0023] 3. This invention achieves the cleaning of residual metal chips inside the metal seal by setting a suction part on one side of the milling cutter. During the machining of the cutting groove on the reverse side of the metal seal, the suction shell always sticks to the inner wall of the cutting groove to scrape off the chips, avoiding the chips from sticking to the side wall and causing damage such as chipping of the milling cutter.

[0024] 4. By setting up components such as suction pipe and liquid inlet in the suction part, the present invention can extract the coolant remaining inside the cutting groove in time during the machining of the cutting groove on the reverse side of the metal seal during the machining process. This allows the coolant sprayed later to reach the milling cutting surface and form effective cooling.

[0025] 5. This invention uses the relative displacement design between the compression plate and the liquid extraction shell to block the liquid inlet during the initial cutting stage to prevent coolant from flowing into the liquid inlet, accurately match the residual amount of coolant, prevent coolant from accumulating in the cutting groove, ensure continuous and effective cooling of the cutting surface, and avoid machining deviations caused by thermal deformation of metal seals.

[0026] 6. This invention provides a guide plate on the outside of the liquid extraction shell. The guide plate scrapes along the outer wall of the liquid extraction shell to clean the chips on the inner wall of the cutting groove and the surface of the liquid extraction shell in real time. This avoids secondary scratches caused by chip accumulation, ensures the machining accuracy of the cutting groove surface, and prevents chips from interfering with the milling cutter cutting, reducing the probability of milling cutter chipping and wear, and extending the tool life.

[0027] 7. This invention uses a compression plate to block and a hydraulic impact unblocking structure to prevent chips from entering the suction pipe and causing blockage. On the other hand, the high-pressure impact of the coolant generated by the rapid downward movement of the compression plate flushes away residual chips in the inlet, completely solving the problem of inlet blockage, preventing the suction pipe from sucking dry, ensuring the stability of the coolant pumping function, and maintaining the overall reliability of the fixture device.

[0030] The technical solutions of 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.

[0031] Example 1 Existing technologies in such Figure 10 The processing of the ultra-thin, irregularly shaped metal seal 8 exhibits numerous technical defects and processing drawbacks: The front and back sides of the ultra-thin, irregularly shaped metal seal 8 require specialized fixtures of different specifications, necessitating multiple processing units to operate separately. This significantly increases equipment investment costs, complicates the overall processing procedure, consumes substantial manpower and resources, and results in low processing efficiency. Furthermore, when processing the front side of the ultra-thin, irregularly shaped metal seal 8, the clamping fixtures lack effective limiting and support for the metal seal 8, causing it to vibrate easily with the cutting tool and affecting processing quality. When processing the back side of the metal seal 8, it needs to be fitted into the limiting groove of the rotating table 2. After processing, the metal seal 8 easily becomes stuck inside the limiting groove. If manual removal is used... Removing the part by prying it out from one side can easily cause plastic deformation of the metal seal 8, directly leading to the scrapping of the metal seal 8 and a decrease in the yield rate. During the machining of the cutting groove on the reverse side of the metal seal 8, the coolant sprayed from the spray pipe tends to accumulate inside the cutting groove and cannot be discharged in time. This makes it difficult for the subsequently sprayed coolant to reach the milling cutting surface and cannot form effective cooling. The heat generated by the continuous milling of the metal seal 8 cannot be dissipated quickly, which can easily cause thermal deformation and thus cause machining dimensional deviations. The metal chips generated by milling will remain inside the cutting groove with the coolant or adhere to the side wall of the cutting groove. If they are not cleaned in time, the chips will interfere with the normal cutting action of the milling cutter, which will not only affect the surface and dimensional accuracy of the cutting groove, but may also cause the milling cutter to chip and wear, shortening the tool life.

[0032] This invention provides, for example Figures 1 to 9 The fixture shown includes a fixed table 1 and a rotating table 2. The rotating table 2 is equipped with a metal seal 8. The fixed table 1 is fixedly installed inside the machine tool 9, and the rotating table 2 is rotatably connected to the outer surface of the fixed table 1. For example, when this fixture is used in a CNC milling machine, the fixed table 1 is located inside the milling machine and its position remains unchanged. The rotating table 2 can rotate around the fixed table 1 and drive the metal seal 8 to rotate. At this time, the milling cutter rotates and feeds continuously, thereby realizing continuous and stable processing of the metal seal 8.

[0033] It also includes an adjustment unit 4, which is disposed inside the rotating table 2, including a moving part 401 and a support part 402. When the metal seal 8 is being machined, the support part 402 supports and limits the metal seal 8. The outer diameter of the moving part 401 is the same as the inner diameter of the metal seal 8. When machining the front side, the moving part 401 provides stable support and limits the metal seal 8. A suction unit 5, multiple sets of which are symmetrically arranged on the upper side of the rotating table 2, is also included. This application uses two sets as an example, but the number can be adjusted according to actual needs. It includes a suction shell 501. When machining the metal seal 8... When the front side of the metal seal 8 is machined, the liquid extraction shell 501 presses down on the top of the metal seal 8 to improve machining stability. When the back side of the metal seal 8 is machined, the liquid extraction shell 501 draws out the residual coolant inside the metal seal 8 and scrapes off the residual chips. The actuating part 6, which is located inside the suction part 5, includes a compression plate 601 and a guide plate 603. When the suction part 5 draws out the residual chips and coolant inside the metal seal 8, the moving part 401 drives the compression plate 601 and the guide plate 603 to move synchronously to prevent the components inside the suction part 5 from being blocked by chips.

[0034] The movable component 401 is movably connected between the fixed table 1 and the rotating table 2. The outer diameter of the movable component 401 is the same as the inner diameter of the metal seal 8. When machining the front side of the metal seal 8, the movable component 401 moves upward to cooperate with the support component 402 to support and limit the metal seal 8. When machining the back side of the metal seal 8, the movable component 401 works in cooperation with the suction part 5 and the actuating part 6. At the same time, the height of the upper surface of the movable component 401 is lower than the height of the upper surface of the rotating table 2 and forms a redundant groove with the rotating table 2, which facilitates the entry of the milling cutter. After the milling cutter has finished entering the table, the movable component 401 moves upward to be level with the height of the rotating table 2. A working cavity 7 is provided on the upper side of the rotating table 2 near the fixed table 1. The support component 402 is movably connected inside the working cavity 7. The working cavity 7 limits the movement of the support component 402. The support component 402 is located outside the movable component 401 and has an assembly cavity 403 inside. When cutting the metal seal 8, the support component 402 supports the bottom of the metal seal 8.

[0035] The adjustment part 4 also includes: a limiting member 404, which is disposed in the assembly cavity 403 inside the support member 402, and its side wall is fixedly connected to the side wall of the moving member 401. The limiting member 404 moves synchronously with the moving member 401 in the assembly cavity 403. When the limiting member 404 moves to a certain distance, the limiting member 404 abuts against the upper or lower surface of the assembly cavity 403 to drive the support member 402 to move; and a telescopic member 405, which is disposed on the lower side of the moving member 401 to drive the moving member 401 to move up and down. The moving member 401, the support member 402, the limiting member 404 and the telescopic member 405 all rotate synchronously with the rotating table 2 around the fixed table 1, thereby improving the supporting and limiting effect of the support member 402 on the metal seal 8.

[0036] A movable part 3 is provided at the top axis of the fixed platform 1. The output end of the movable part 3 is fixedly connected to the top of the liquid extraction shell 501. Both the movable part 3 and the telescopic part 405 can be electric push rod structures. The output end of the movable part 3 can not only drive the liquid extraction shell 501 to move vertically above the metal seal 8, further improving the subsequent assembly, support and impurity removal effect, but also drive the liquid extraction shell 501 to move laterally, thereby realizing that the liquid extraction shell 501 and the milling cutter move in the same height and position, ensuring that the liquid extraction shell 501 scrapes and cleans the chips generated during the milling process in real time.

[0037] A milling cutter and a spray pipe are arranged above the fixed table 1 and the rotating table 2, and the milling cutter and the spray pipe are located between multiple liquid extraction shells 501. Therefore, when the rotating table 2 drives the metal seal 8 to rotate, the milling cutter only rotates on its own axis and does not rotate. Under the limit of the movable part 3, the liquid extraction shell 501 also does not rotate. Therefore, the metal seal 8 first moves to the bottom of the spray pipe, the spray pipe sprays coolant downward and pre-cools the processing position. Then the metal seal 8 is pressed into contact with the milling cutter and is processed. The metal seal 8 is in contact with the liquid extraction shell 501 and performs liquid extraction and impurity removal processes.

[0038] A suction pipe 502 is provided above the liquid extraction shell 501. During the machining of the cutting groove on the reverse side of the metal seal 8, it is used to extract the residual coolant in the cutting groove. The suction pipe 502 passes through the output end of the movable part 3 and is connected to the recovery tank through the pump body. When the pump body is started, it applies suction force to the inside of the liquid extraction shell 501 through the suction pipe 502. The liquid extraction shell 501 is used to scrape off the residual chips in the cutting groove. An inlet 503 is provided inside one side of the liquid extraction shell 501 for extracting the residual coolant in the cutting groove. A flow cavity 504 is formed inside the inlet 503.

[0039] For example, the ultra-thin irregular metal seal 8 tooling fixture is used on a milling machine, which includes a housing, a fixed table 1 and a rotary table 2, all located inside the housing to provide a stable environment for the cutting of the metal seal 8; a tool post is provided inside the housing, and multiple sets of milling cutters are provided at the lower end of the tool post for cutting the metal seal 8.

[0040] In summary, in the initial standby state, all functional components of this metal seal fixture are precisely positioned in their preset initial positions, and the entire fixture is in a stable state ready for processing. The core transmission component, the moving part 401, is at its highest vertical stroke position under the rigid support of the output end of the telescopic part 405. In this state, the upper surface of the limiting part 404 and the lower surface of the internal assembly cavity 403 of the support part 402 achieve a tight and seamless contact. The support part 402, under the stable support of the limiting part 404, protrudes upwards from the upper surface of the rotating table 2, forming a significant height difference. This design effectively prevents processing debris, residual coolant, and other impurities from entering the mating area between the moving part 401 and the support part 402, maintaining the cleanliness of their mating surfaces. This avoids component jamming and wear problems caused by debris accumulation from the source, ensuring smooth transmission and accurate positioning of each component during subsequent processing, laying the foundation for industrial continuous processing.

[0041] When the ultra-thin irregular metal seal 8 is being machined from the front, the telescopic component 405 is activated to move its output end downwards smoothly, thereby driving the moving component 401 to move downwards synchronously along the vertical direction of the working cavity 7. The downward movement of the moving component 401 will pull the limiting component 404 to slide downwards in a directional manner along the assembly cavity 403 inside the support component 402. The downward movement of the limiting component 404 causes the support component 402 to lose its upward supporting force. Under its own gravity, the support component 402 will move downwards smoothly and synchronously with the limiting component 404. The entire movement process is precisely guided by the assembly cavity 403, without deviation or jamming, until the upper surface of the support component 402 is completely flush with the upper surface of the rotating table 2. The output end of the telescopic component 405 immediately stops moving and completes the position locking.

[0042] At this time, the upper surface of the moving part 401 is still higher than the flush plane of the support part 402 and the rotating table 2, forming an independent support boss. The support part 402 maintains a stable static state under the rigid limiting action of the limiting part 404. Since the inner diameter of the metal seal 8 and the outer diameter of the moving part 401 are precisely matched, the operator can quickly and accurately place the metal seal 8 to be processed on the preset processing position of the rotating table 2, so that the inner ring of the metal seal 8 and the outer ring of the moving part 401 are tightly fitted. During the front milling process, the moving part 401 forms a dual function of radial limiting and axial support for the ultra-thin irregular metal seal 8, which can effectively offset the cutting force generated by milling, prevent the metal seal 8 from shifting or moving due to force, fundamentally avoid the processing deviation and processing failure caused by the displacement of the metal seal 8, and ensure the dimensional accuracy and surface accuracy of the front processing.

[0043] Afterwards, multiple moving parts 3 are activated, causing the suction shell 501 to move downwards and press against the top of the metal seal 8. The two sets of suction shells 501 are then symmetrically positioned above the metal seal 8 and pressed downwards for limiting. This, in conjunction with the support 402, achieves stable clamping and fixing of the metal seal 8, preventing it from shaking during processing and affecting its normal processing effect. Then, the milling cutter rotates and moves downwards above the metal seal 8. At the same time, the rotating table 2 drives the metal seal 8 to rotate around the fixed table 1, and the support 402 and the moving parts 401 rotate synchronously. During this process, the moving parts 401 always maintain contact and support against the inner wall of the metal seal 8, preventing it from shifting during rotation and affecting processing accuracy. Then, in conjunction with the revolution of the metal seal 8 and the rotation of the milling cutter, the processing of the front of the metal seal 8 is achieved. During the processing of the front of the metal seal 8, the coolant is flushed and falls onto the rotating table 2. At this time, in conjunction with the rotation of the rotating table 2, the coolant is thrown out by centrifugal force, so as not to affect subsequent processing.

[0044] After the front processing of the metal seal 8 is completed, the worker will carefully remove the processed metal seal 8 and restart the telescopic component 405 so that its output end continues to extend and retract downward. The output end of the telescopic component 405 drives the moving component 401 and the limiting component 404 to move downward in sequence along the vertical direction of the working cavity 7. During the downward movement, the limiting component 404 simultaneously drives the support component 402 to move downward until the lower surface of the support component 402 is in close contact with the bottom of the working cavity 7. At this time, the rotating table 2 provides stable rigid support for the support component 402 to ensure its positional stability in the subsequent processing.

[0045] Subsequently, the output end of the telescopic component 405 continues to drive the moving component 401 and the limiting component 404 to move downwards until the lower surface of the limiting component 404 precisely abuts against the lower surface of the internal assembly cavity 403 of the support component 402, at which point the output end of the telescopic component 405 completes the position locking. In this state, the height value of the upper surface of the moving component 401 is higher than the height value of the upper surface of the support component 402 but lower than the height value of the upper surface of the outer ring of the rotating table 2. The outer ring of the rotating table 2, the moving component 401, and the support component 402 together form an annular cutting groove whose specifications are precisely matched with the metal seal 8. This groove serves as a dedicated placement position for the reverse side processing of the metal seal 8, enabling rapid positioning and circumferential limiting of the metal seal 8.

[0046] Meanwhile, a redundant annular groove is formed between the upper surface of the moving part 401 and the outer ring of the rotating table 2, which is connected to the annular cutting groove. The recess depth of the redundant annular groove is smaller than that of the annular cutting groove. This structural design not only greatly reduces the difficulty of picking up and putting down the metal seal 8 during reverse machining and avoids jamming of the metal seal 8, but also provides more operating space for the milling cutter's cutting operation, making the milling cutter's feed, retraction and cutting actions more flexible, effectively improving the operational convenience and machining accuracy of reverse machining.

[0047] After the metal seal 8 is precisely placed in the annular cutting groove, the machining process of the reverse cutting groove is officially started. The output end of the movable part 3 drives the two sets of suction parts 5 to move down synchronously and accurately position them to the preset machining position above the metal seal 8. Then, the milling cutter feeds smoothly downward in the vertical direction and mills the cutting groove on the reverse side of the metal seal 8. During the milling cutter feed, the movable part 3 drives the suction parts 5 to move down synchronously, which further improves the suction and recovery effect of the suction parts 5 on the coolant. The two sets of suction parts 5 are symmetrically arranged inside the cutting groove. The liquid extraction shell 501 presses against the bottom of the cutting groove and cooperates with the support part 402 to support and limit the bottom of the metal seal 8, which further improves the clamping and fixing stability of the milling cutter when machining the metal seal 8.

[0048] During the process of the milling cutter continuously cutting the cutting groove, the rotating table 2 drives the metal seal 8 to revolve, while the two sets of liquid extraction shells 501 and the milling cutter do not rotate. The side walls of the two sets of liquid extraction shells 501 are always in close contact with the cutting position of the cutting groove and move relative to each other. This timely and thorough scraping off the metal chips remaining in the cutting groove during the milling process prevents the chips from adhering to the wall of the cutting groove or accumulating in the core cutting area, prevents the chips from interfering with the normal cutting action of the milling cutter, and ensures the milling accuracy and the surface finish of the cutting groove.

[0049] Simultaneously, during the real-time chip removal process of the two sets of liquid extraction shells 501, the suction pipe 502 continuously applies negative pressure to the flow chamber 504 inside the two sets of liquid extraction shells 501, ensuring a stable negative pressure environment within the flow chamber 504. The coolant sprayed in the cutting groove due to milling cooling requirements is rapidly drawn into the flow chamber 504 through the liquid inlet 503 on the liquid extraction shell 501 under the suction effect of negative pressure. Subsequently, it is promptly extracted from the processing area through the suction pipe 502. The continuously extracted coolant can cooperate with the milling process to efficiently circulate and cool the cutting surface, continuously removing the heat generated by milling, ensuring that the temperature of the milling area remains within a stable range, preventing the ultra-thin irregular metal seal 8 from undergoing plastic deformation due to local overheating, and also effectively preventing coolant accumulation in the cutting groove, avoiding the inability of subsequent coolant to reach the cutting surface due to coolant accumulation, ensuring the normal and continuous operation of subsequent milling operations, and achieving synchronous coordination of cutting and cooling.

[0050] The milling cutter then moves away from the fixed table 1 and increases the cutting width. Meanwhile, the movable part 3 drives the liquid extraction shell 501 to move synchronously and keep its side wall in close contact with the milling cutter's cutting surface. This further ensures the cleaning effect of the side wall of the liquid extraction shell 501 and the guide plate 603 on the cutting position, preventing some chips from remaining on the machining surface and affecting the subsequent machining quality.

[0051] After the machining of the reverse cutting groove of the metal seal 8 is completed, the output end of the movable part 3 is first extended, which drives the liquid extraction shell 501 to move upward and disengage from the clamping and fixing above the metal seal 8. At the same time, the milling cutter retracts. Then, the telescopic part 405 is activated to make its output end move upward smoothly, which drives the movable part 401 and the limiting part 404 to move upward synchronously in the vertical direction. As the limiting part 404 continues to move upward along the assembly cavity 403, its upper end face makes precise contact with the lower surface of the assembly cavity 403 inside the support part 402. The upward movement of the subsequent limiting member 404 will simultaneously drive the support member 402 to move upward smoothly. During the upward movement of the support member 402, its upper end face will form a uniform upward pushing force on the metal seal 8 embedded in the annular cutting groove, lifting the metal seal 8 upward smoothly along with the support member 402. This pushing method is a surface contact force, which can effectively avoid deformation caused by single-point force on the metal seal 8, and at the same time fundamentally avoid the problem of the metal seal 8 being stuck in the annular cutting groove after processing and difficult to remove.

[0052] Until the support member 402 moves the metal seal 8 up to the annular cutting groove area completely separated from the rotating table 2, the operator can easily and quickly remove the processed metal seal 8, thus completing the overall processing of the metal seal 8. Then, the telescopic member 405 continues to move all components, including the moving member 401, the limiting member 404, and the support member 402, upward to the initial standby position. Each component is precisely returned to its position, waiting for the start of the next processing operation. The entire processing flow is smooth and continuous, without the need for manual fixture replacement, realizing integrated forward and reverse processing operation.

[0053] Example 2 Based on the above embodiments, there are still several technical defects that need to be addressed: the inlet 503 is always fully open throughout the entire cutting process, which not only wastes pumping power but also easily causes local air suction and air explosion, damaging the device; during the continuous scraping of chips from the inner wall of the cutting groove by the two sets of pumping shells 501, the scraped chips tend to accumulate on the outer wall surface of the pumping shell 501. The accumulated chips will have secondary contact friction with the inner wall of the cutting groove as the pumping shell 501 rotates and mills, thus causing secondary scratches on the side wall of the machined cutting groove and reducing the surface machining accuracy of the cutting groove; when the suction pipe 502 continuously pumps coolant from the cutting groove through the inlet 503, the metal chips mixed in the coolant tend to accumulate and block the inlet 503, which not only causes negative pressure air suction in the suction pipe 502 but also causes the coolant in the ultra-thin cutting groove to accumulate continuously and not be discharged, thus affecting the overall operational stability of the fixture device.

[0054] To solve the above problems, a guide plate 603 is disposed on the outside of the liquid extraction shell 501 and slidably connected to the liquid extraction shell 501. The height of its surface gradually decreases from one end of the liquid extraction shell 501 to the other end, and is used to scrape off the chips accumulated on the surface of the liquid extraction shell 501. A drainage groove 607 is provided on the guide plate 603, and the depth of the drainage groove 607 gradually increases from one end of the follower plate 604 to the other end, and is used to discharge the chips on the guide plate 603. A compression plate 601 is disposed inside the liquid extraction shell 501. The side of the compression plate 601 away from the liquid inlet 503 is a slope, and the side of the liquid extraction shell 501 away from the liquid inlet 503 is a wedge-shaped surface. The slope and the wedge-shaped surface slide in a wedge-shaped fit. When the moving part 401 drives the guide plate 603 to move up and down reciprocatingly, the compression plate 601 moves synchronously with the guide plate 603 to squeeze the coolant in the flow cavity 504.

[0055] The docking holes 602 are evenly distributed inside the compression plate 601 and are used to transport the coolant in the flow cavity 504. The diameter of the docking holes 602 is smaller than the diameter of the inlet 503. When the moving member 401 drives the compression plate 601 to move up and down inside the flow cavity 504, the coolant inside the flow cavity 504 flows out along the docking holes 602. The compression plate 601 moves down rapidly under the action of the elastic member 606, which causes the coolant on the lower side of the compression plate 601 in the flow cavity 504 to form an instantaneous hydraulic impact. Due to the flow restriction effect of the docking holes 602, the coolant cannot flow upward quickly and can only be rushed out rapidly and under high pressure from the inlet 503, utilizing the instantaneous impact force of the coolant.

[0056] The actuating part 6 further includes: a connector 605, which is slidably and sealingly connected to the inside of the liquid inlet 503, and is elastic enough to be stretched or compressed. One end is connected to the compression plate 601, and the other end is connected to the guide plate 603. The connector 605 moves synchronously with the guide plate 603; a follower plate 604, which is disposed on the upper surface of the guide plate 603 and has an inverted "L" shape, used to drive the guide plate 603 to move, and one side of which is connected to the slot block of the liquid extraction shell 501; and an elastic member 606, which is disposed inside the flow cavity 504, and one end is connected to the compression plate 601. Plate 601 abuts against the flow chamber 504, and the other end is fixedly connected to the top of the flow chamber 504. It is used to drive the compression plate 601 to reset and squeeze the coolant in the flow chamber 504. The side wall of the follower plate 604 is provided with a locking block, and the side wall of the liquid extraction shell 501 is provided with a locking groove. The locking block and the locking groove are slidably connected. Therefore, the follower plate 604 can only drive the guide plate 603 to move up and down and cannot move laterally. That is, the elastic member 606 is elastic and can only drive the compression plate 601 to move laterally inside the flow chamber 504 and change the blocking position of the liquid inlet 503.

[0057] Furthermore, an elastic baffle is provided at the top of the inlet 503 to block the top of the inlet 503, preventing the coolant inside the cutting groove from flowing above the inlet 503 and affecting the suction effect. When the guide plate 603 drives the connector 605 to move upward, the connector 605 and the elastic baffle are elastically squeezed and deformed. Therefore, the connector 605, together with the elastic baffle, still achieves the sealing and blocking of the top of the inlet 503, preventing outside air from entering the flow cavity 504 from the top of the inlet 503 and causing an air explosion. At the same time, the guide plate 603 continues to move upward and the lowest end of the diversion groove 607 passes the coolant and is located above the metal seal 8, thereby facilitating the uniform and thorough flow and discharge of the chips inside the diversion groove 607.

[0058] In summary, in the initial standby state, the compression plate 601 is naturally stationary at the lowest limit position inside the liquid extraction shell 501 under the action of its own weight and the elastic force of the elastic element 606. At this time, the connecting part 605 elastically resets, and the inclined surface on the compression plate 601 fits against the wedge-shaped surface inside the liquid extraction shell 501. When the suction pipe 502, the flow chamber 504, and the liquid inlet 503 enter the normal working state, the coolant in the processing area will enter the lower half of the flow chamber 504 through the liquid inlet 503 under the action of negative pressure. The fine chips mixed in the coolant will be initially blocked by the liquid inlet 503. The filtered coolant will pass through the docking hole 602 on the compression plate 601 and flow smoothly into the upper half of the flow chamber 504. Finally, it will be quickly discharged by the suction pipe 502 through negative pressure, realizing the integration of coolant filtration and drainage, and ensuring the cleanliness of the cooling pipeline.

[0059] When the milling cutter is preparing to machine the cutting groove on the reverse side of the metal seal 8, the milling cutter first completes a precise feed along the redundant annular groove of the rotary table 2. When the milling cutter reaches the preset cutting position and starts the cutting operation, the telescopic component 405 moves upward, driving the moving component 401 to move upward in the vertical direction synchronously until the upper surface of the moving component 401 abuts against the lower surface of the follower plate 604. The telescopic component 405 immediately stops its movement and completes the position locking. In the initial stage of the cutting operation, the cutting groove on the metal seal 8 is relatively shallow. Most of the coolant and chips can flow autonomously along the side wall of the cutting groove and be discharged to the outside of the machining area by their own gravity. Only a small amount of coolant and chips remain in the cutting groove. At this time, the output end of the moving component 3 drives the liquid extraction shell 501 to move downward with the milling cutter. As the height is lowered synchronously, the guide plate 603 and follower plate 604 maintain a constant height due to the rigid limiting effect of the moving part 401. This causes the compression plate 601 to undergo relative vertical displacement with the liquid inlet 503 on the liquid extraction shell 501. The compression plate 601 moves upward relative to the liquid extraction shell 501 along the wedge-shaped surface inside the liquid extraction shell. During the movement, the compression plate 601 continuously squeezes the connecting part 605. Finally, the compression plate 601 adheres to the inner wall of the liquid extraction shell 501 near the liquid inlet 503. The compression plate 601 blocks the upper part of the liquid inlet 503, ensuring that the liquid level of the coolant is always higher than the lower part of the liquid inlet 503 and the height of the part that overlaps with the flow cavity 504. This prevents the ineffective waste of the suction power of the suction pipe 502 and the occurrence of local cavitation causing air explosion.

[0060] Furthermore, the deeper the cutting groove, the greater the downward movement distance of the suction shell 501. With the position of the moving part 401 remaining unchanged, the suction shell 501 moves downward relative to the follower plate 604. The follower plate 604, through the guide plate 603 and the connecting part 605, drives the compression plate 601 to move upward relative to the flow cavity 504. The relative displacement between the compression plate 601 and the inlet 503 also increases accordingly. The overlapping area between the inlet 503 and the flow cavity 504 increases synchronously. The suction force precisely matches the coolant accumulation in the cutting groove, achieving adaptive suction of the coolant and effectively preventing continuous accumulation of coolant in the cutting groove, ensuring the cooling effect of the milling area. When the coolant height is completely higher than the height of the inlet 503, the telescopic part 405 drives the moving part 401 to move downward. The follower plate 604 loses its supporting force, and the compression plate 601 moves downward along the wedge-shaped surface inside the suction shell 501 under the action of the elastic part 606. Finally, the compression plate 601 stops at the bottom of the suction shell 501.

[0061] Furthermore, during the process of the follower plate 604 driving the guide plate 603 to move up and down, the follower plate 604 and the slot block of the liquid extraction shell 501 limit the movement of the guide plate 603. The follower plate 604 can only drive the guide plate 603 to move up and down on the side wall of the liquid extraction shell 501 and cannot move laterally. Therefore, when the compression plate 601 moves down to the lowest end inside the liquid extraction shell 501, under the elastic force of the elastic element 606, the inclined surface of the compression plate 601 moves away from the end of the guide plate 603 along the wedge-shaped surface inside the liquid extraction shell 501. The compression plate 601 no longer blocks the liquid inlet 503, and the liquid inlet 503 is in the normally open state.

[0062] During the continuous milling of the cutting groove by the milling cutter, the sidewalls of the two sets of liquid extraction shells 501 away from the fixed table 1 always move in contact with the inner wall of the cutting groove machining surface, scraping off the metal chips adhering to the sidewall of the cutting groove in real time, ensuring the surface machining accuracy of the cutting groove. However, during this process, some of the scraped chips will continuously accumulate on the outer wall surface of the liquid extraction shell 501, and most of the chips will continuously flow into the interior of the drainage groove 607 through the guide plate 603. If not cleaned in time, the accumulated chips will cause secondary friction with the sidewall of the cutting groove as the liquid extraction shell 501 rotates, causing secondary scratches on the sidewall of the cutting groove. At the same time, it will also increase the rotational resistance of the liquid extraction shell 501, affecting the stability of the milling operation.

[0063] At this time, the telescopic component 405 will extend upward again and drive the moving component 401 to move slightly upward. The distance of this upward movement is still less than the height of the internal assembly cavity 403 of the support component 402, which can effectively prevent the limiting component 404 from excessively contacting the assembly cavity 403 as the moving component 401 moves upward, ensuring that the support component 402 always maintains a stable support state. The movement of the moving component 401 drives the follower plate 604 to move upward. The upward movement of the follower plate 604 drives the guide plate 603 to move smoothly upward along the outer wall of the liquid extraction shell 501. The side wall of the guide plate 603 is closely attached to the outer wall of the liquid extraction shell 501 and, during the movement, completely scrapes away all the chips accumulated on the surface of the liquid extraction shell 501, especially on the outer surface of the liquid inlet 503. Afterwards, the guide plate 603 moves upward above the metal seal 8, and the guide plate 603 drives the connector 605 to squeeze the elastic baffle and cause elastic deformation. The elastic baffle, together with the connector 605, still blocks the upper part of the liquid inlet 503, and the lower part of the connector 605 is still inside the coolant, to prevent outside air from entering the flow chamber 504 along the liquid inlet 503 and causing air explosion and other problems. At this time, the lowest point of the drainage groove 607 is higher than the upper surface of the metal seal 8. Under the action of the centrifugal force of the rotating table 2, the chips in the drainage groove 607 flow to the area above the metal seal 8 outside the cutting groove. Then the coolant will quickly flush the chips to the outside of the processing area, to prevent the chips from accumulating on the surface of the liquid extraction shell 501 for a long time.

[0064] Simultaneously, the upward movement of the follower plate 604, via the guide plate 603 and connector 605, drives the compression plate 601 upward. Under the continuous pushing action of the moving part 401, the compression plate 601 moves to the highest limit position inside the liquid extraction shell 501. The elastic part 606 is in a compressed state, forming a strong elastic restoring potential energy. At this time, the telescopic part 405 drives the moving part 401 to instantly and quickly retract to the support position. After the compression plate 601 loses the constraint of the pushing force, under the elastic restoring force of the elastic part 606, it moves rapidly downward along the inner wall of the liquid extraction shell 501. Due to the mating hole 602 opened on the compression plate 601... The diameter of the inlet is smaller than that of the inlet 503. The rapid downward movement of the compression plate 601 will cause the coolant on the lower side of the compression plate 601 in the flow chamber 504 to form an instantaneous hydraulic shock. Due to the flow restriction effect of the docking hole 602, the coolant cannot flow upward quickly and can only be rushed outward at high pressure from the inlet 503. The instantaneous reverse impact force of the coolant will completely flush away the metal chips that remain and accumulate on the inner wall of the inlet 503, preventing problems such as negative pressure suction and inability of coolant to be discharged normally caused by chip blockage in the inlet 503, and avoiding damage to the components of the device caused by coolant accumulation and abnormal negative pressure.

[0065] Simultaneously, as the follower plate 604 drives the connector 605 to move up and down along the inlet 503, the connector 605 can scrape and clean the chips blocking the inside of the inlet 503, preventing them from clogging the inside of the inlet 503 and affecting the suction and recovery effect of the inlet 503 on the coolant inside the cutting groove. At the same time, when the guide plate 603 drives the compression plate 601 to move upward along the flow cavity 504 through the connector 605, the inclined surface at the end of the compression plate 601 and the wedge-shaped surface of the inner wall of the flow cavity 504 work together to drive the compression plate 601 to move upward. 01 The elastic element 606 is squeezed and moved towards the guide plate 603. The compression plate 601 partially blocks the upper part of the liquid inlet 503, and the suction area of ​​the liquid inlet 503 changes accordingly. At the same time, under the stable suction force applied by the suction pipe 502, the suction force applied by the liquid inlet 503 to the coolant and chips inside the cutting groove changes accordingly. This further effectively achieves the uneven suction and recovery effect of the chips accumulated and adhered inside the cutting groove, avoiding them from being subjected to a single suction force for a long time, which would cause them to stick together and reduce the suction and recovery effect.

[0066] As the milling cutter continues to feed downwards, the movable part 3 synchronously drives the liquid extraction shell 501 to move downwards, ensuring that its bottom corresponds to the bottom of the milling cutter. When the guide plate 603 needs to move upwards to scrape and clean the chips inside the liquid inlet 503 and the cutting groove, the extension distance of the output end of the telescopic part 405 increases. Correspondingly, the output end of the telescopic part 405 drives the movable part 401 to move upwards by an increased distance. The movable part 401 drives the guide plate 603 to move upwards by an increased amount through the follower plate 604. The guide plate 603 drives the connecting part 605 to move upwards and increases the degree of squeezing the elastic baffle. Thus, the guide plate 603 pushes the chips inside the drainage groove 607 upwards to an increased height, ensuring that they are above the rotating part 2. This facilitates the chips falling along the inside of the drainage groove 607 to the top of the rotating part 2 and being rotated and discharged under the action of centrifugal force.

[0067] During the milling process of the milling cutter continuously milling the cutting groove, an outward transverse cutting force is generated. The liquid suction shells 501 of the two sets of suction parts 5 are symmetrically attached to the machining surface of the annular cutting groove of the metal seal 8, forming a bidirectional and opposite rigid abutment force from the left and right sides. This can accurately offset the transverse cutting force generated by the milling operation, so that the metal part has no displacement deviation during the cutting process of the rotating table 2, ensuring the radial dimensional accuracy of the cutting groove. At the same time, the two sets of liquid suction shells 501 form a bidirectional symmetrical pressing force on the metal seal 8 in the vertical direction, which can keep the ultra-thin irregular metal seal 8 with poor rigidity in a horizontal state during high-speed rotation cutting. This completely avoids the problem of slight warping and plastic deformation of the metal part caused by the single suction part 5 pressing on one side, ensuring the overall machining flatness and surface consistency of the annular cutting groove.

[0068] Two sets of guide plates 603 move up and down along the cutting groove machining surface in sync with the liquid extraction shell 501, which can quickly discharge the scraped metal chips to the outside of the annular cutting groove in both directions. Compared with the operation mode of single guide plate 603 scraping on one side, the chips are easy to transfer to the non-operation side with the common direction of the metal seal 8 and accumulate and stick to the cutting groove wall. The double-sided synchronous scraping can realize the immediate bidirectional removal of chips, completely avoid the circumferential transfer of chips in the annular machining area, and at the same time prevent the accumulated chips from secondary contact with the cutting groove wall and the milling cutter, thus ensuring the surface machining accuracy of the cutting groove.

[0069] The two suction units 5 adopt a symmetrical redundant structure design. Compared with the single suction unit 5, which requires shutdown for maintenance if a fault such as blockage of the liquid inlet 503 or jamming of the guide plate 603 occurs, the two suction units 5 can continue to operate normally and complete basic operations such as pressing the metal parts, scraping the chips off the wall of the cutting groove, and pumping out the coolant when one unit fails. This effectively ensures the continuous operation of the milling process, greatly reduces the unplanned downtime rate of the equipment, and perfectly adapts to the production needs of industrialized batch continuous processing.

[0070] As the milling cutter moves away from the fixed table 1 to achieve feed machining in the width direction, the movable part 3 drives the liquid extraction shell 501 to move away from the fixed table 1 in sync. The side wall of the liquid extraction shell 501 is always in contact with the machining surface of the cutting groove, and works with the liquid extraction shell 501 and the guide plate 603 to effectively scrape and clean the chips. At the same time, during this process, some of the coolant inside the cutting groove flows backward along the liquid extraction shell 501 and the inner wall of the cutting groove near the fixed table 1. That is, a single liquid extraction shell 501 cannot guarantee the uniform and complete extraction and recovery of the coolant inside the cutting groove. At this time, with the help of multiple liquid extraction shells 501, not only is the stable support and limit of the metal seal 8 improved during the cutting process, but the coolant inside the cutting groove is also continuously extracted and scraped cleaned by multiple liquid extraction shells 501, further ensuring that there are no chips or used coolant flowing at the milling cutter position and that it can be reused, thereby improving the cutting stability and efficiency of the subsequent milling cutter.

[0071] After the cutting groove machining of the metal seal 8 is completed, the telescopic component 405 drives the moving component 401 and the support component 402 to move upward synchronously in the vertical direction of the working cavity 7. Through the surface contact pushing method, the machined metal seal 8 is smoothly pushed out of the annular groove, avoiding plastic deformation of the ultra-thin irregular metal seal 8 during the pushing process (as described in Embodiment 1), ensuring the accuracy of the machined product. After the metal seal 8 is successfully removed, the telescopic component 405 drives the moving component 401, the limiting component 404 and other functional components to reset in sequence. The compression plate 601 also returns to the lowest position inside the liquid extraction shell 501 under the combined action of gravity and the elastic component 606. All components return to the initial standby position, completing a complete machining cycle and waiting for the start of the next machining operation. The whole process does not require manual intervention, realizing automated machining and unblocking operations, and greatly improving machining efficiency.

[0072] Example 3 A fixture for ultra-thin irregular-shaped metal seals and its method of use. The method utilizes the fixture to clamp and fix the metal seal, including the following steps: S1. When the metal seal 8 is being machined from the front, the support 402 is flush with the upper surface of the rotating table 2, the height of the moving part 401 is higher than the height of the support 402, and multiple sets of liquid extraction shells 501 press on the top of the metal seal 8.

[0073] S2, prepare for reverse machining of metal seal 8, support 402 moves down to the maximum distance, and the height of moving part 401 is higher than the height of support 402.

[0074] S3. When the metal seal 8 is being machined on the reverse side, the metal seal 8 is rotated and cut along with the rotary table 2. The overlapping area of ​​the liquid inlet 503 and the compression plate 601 decreases continuously as the groove depth increases, and the liquid inlet 503 continuously draws in coolant.

[0075] S4. When the tank depth is greater than the height of the inlet 503, the follower plate 604 and the compression plate 601 move downward to the initial position, and the compression plate 601 disengages from blocking the inlet 503.

[0076] S5. The moving part 401 periodically drives the compression plate 601 and the guide plate 603 to move upward to the maximum distance and then retracts. The guide plate 603 moves upward to scrape off the chips accumulated on the surface of the liquid extraction shell 501 and guides the chips out. The compression plate 601 quickly retracts and compresses the coolant in the flow chamber 504, which is then flushed out from the liquid inlet 503.

[0077] S6. After the reverse side is processed, the support 402 is lifted upward to push the metal seal 8 out of the annular cutting groove and remove the metal seal 8.

[0078] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

9. A fixture for ultra-thin irregular-shaped metal seals and its method of use, wherein the method utilizes the fixture for ultra-thin irregular-shaped metal seals as described in any one of claims 1 to 8 to clamp and fix the metal seal, characterized in that... Includes the following steps: S1. When the metal seal (8) is machined on the front, the support (402) is flush with the upper surface of the rotating table (2), the height of the moving part (401) is higher than the height of the support (402), and multiple sets of liquid extraction shells (501) press on the top of the metal seal. S2, metal seal (8) reverse side processing preparation, support (402) moves down to the maximum distance, the height value of moving part (401) is higher than the height value of support (402); S3. When the metal seal (8) is processed on the reverse side, the metal seal (8) is rotated and cut with the rotating table (2). The overlapping area of ​​the liquid inlet (503) and the compression plate (601) decreases continuously as the groove depth increases. The liquid inlet (503) continuously draws in coolant. S4. When the tank depth is greater than the height of the inlet (503), the follower plate (604) and the compression plate (601) move downward to the initial position, and the compression plate (601) disengages from blocking the inlet (503). S5. The moving part (401) periodically drives the compression plate (601) and the guide plate (603) to move upward to the maximum distance and then retracts. The guide plate (603) moves upward to scrape off the chips accumulated on the surface of the liquid extraction shell (501) and guides the chips out. The compression plate (601) retracts and compresses the coolant in the flow chamber (504) so ​​that it is ejected from the inlet (503); S6. After the reverse side is processed, the support (402) is lifted upward to push the metal seal (8) out of the annular cutting groove and remove the metal seal (8).
