Description

Technical Field

[0001] This invention relates to the field of notebook computer casing milling equipment technology, specifically to a notebook computer casing full milling production device and production process. Background Technology

[0002] The full milling of the metal casing of a laptop is a molding process that is different from die casting, stamping, and injection molding. It uses solid aluminum sheet / aluminum billet as raw material directly, without relying on die casting or stamping to make the main shape. The entire structure of the casing, including its shape, internal cavity, thin wall, interface groove, key hole, appearance texture, high-gloss chamfer, etc., is formed in one piece by cutting away the material.

[0003] When milling laptop casings, aluminum alloy is milled into a box shape. The box-shaped casing is relatively thin and has poor rigidity. To prevent deformation of the box-shaped casing, vacuum clamping is usually used for clamping. However, each milling operation generates cutting debris. After each processing, the processing table is blown clean. During the blowing process, debris may adhere to the surface of the vacuum chuck, causing the surface of the vacuum chuck to be uneven. This affects the tight fit between the chuck and the aluminum alloy profile to be processed, resulting in insufficient clamping force and affecting the stability of the milling process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a full milling production apparatus for laptop casings, including a CNC milling machine body, a machining table fixedly connected to the bottom of the inner wall of the CNC milling machine body, a positioning frame fixedly connected to the top of the machining table, and further comprising: A fixing mechanism is installed on the inner wall of the processing table. The fixing mechanism includes several limiting frames installed on the inner wall of the processing table. A shielding mechanism is installed on the inner wall of the processing table. The shielding mechanism includes several connecting frames installed on the inner wall of the processing table. A limiting mechanism is installed on the top of the machining table. The limiting mechanism includes several annular inclined grooves formed on the top of the machining table. In operation, the operator places the aluminum alloy profile workpiece to be processed in the positioning frame, and then fixes the workpiece by the fixing mechanism. After fixing, the CNC milling machine body is started to mill the workpiece.

[0005] Preferably, the fixing mechanism further includes: Adsorption components are installed on the inner wall of the processing table; The driving component is installed on the inner wall of the adsorption component.

[0006] Preferably, the shielding mechanism further includes: The push component is installed on top of the adsorption component; The sealing component is installed on the inner wall of the processing table.

[0007] Preferably, the limiting mechanism further includes: The extrusion assembly is installed on the inner wall of the processing table; The clamping component is installed on the inner wall of the positioning frame.

[0008] Preferably, the adsorption assembly includes a sliding groove formed on the inner wall of the processing table, and the tops of several limiting frames are fixedly connected to the top of the inner wall of the sliding groove. A negative pressure frame is slidably connected to the inner wall of the sliding groove, and several suction cups are fixedly connected to the top of the negative pressure frame; The drive assembly includes an electric telescopic rod fixedly connected to the bottom of the inner wall of the sliding groove. The top of the output end of the electric telescopic rod is fixedly connected to the bottom of the negative pressure frame. A connecting hose is connected through the inner wall of the negative pressure frame. The process involves connecting the hose to an external vacuum pump. Once the workpiece is in place, the electric telescopic rod extends, pushing the negative pressure frame and suction cup upwards.

[0009] Preferably, the pushing component includes several connecting rods rotatably connected to the top of the negative pressure frame, and several sliding rods slidably connected to the top of the inner wall of the sliding groove; The top inner walls of several connecting rods are rotatably connected to the side of several sliding rods away from the connecting hose, and the side of several sliding rods close to the connecting hose are rotatably connected to connecting rods. The bottom inner walls of several connecting rods are rotatably connected to the side of several connecting frames away from the annular inclined groove; The negative pressure frame will push the first connecting rod to rotate, causing the first connecting rod to push the slide rod to move towards the connecting hose. The slide rod will then push the second connecting rod to rotate, which in turn will pull the connecting frame down.

[0010] Preferably, the sealing assembly includes several connecting holes formed on the top of the processing table, and the inner walls of the several connecting holes are slidably connected with sealing rings; The bottom of several sealing rings is fixedly connected to the top of several connecting frames, and the outer wall of several sealing rings is slidably connected to the inner wall of several limiting frames. As the sealing ring continues to descend, it will separate from the connecting hole, the vertical restriction on the sealing ring will disappear, and the sealing ring will be subject to the horizontal lateral restriction of the limiting frame. At this point, the slide bar continues to move towards the connecting hose, which will drive the second connecting rod, the connecting frame and the sealing ring to move synchronously, so that the sealing ring moves away from the connecting hole and opens the connecting hole. As the suction cup continues to move, the suction cup will move into the connecting hole, so that the suction cup is in contact with the bottom of the workpiece. Then the external vacuum pump is started, and a vacuum negative pressure is formed in the negative pressure frame through the connecting hose. The workpiece is tightly adsorbed and fixed by the suction cup. After the workpiece is fixed, the CNC milling machine body is started to mill the workpiece. After processing, the external vacuum pump is restarted to eliminate the vacuum negative pressure in the negative pressure frame and remove the fixation of the workpiece. Then, the electric telescopic rod is retracted, which drives the negative pressure frame and suction cup to descend. The negative pressure frame will pull the first connecting rod to rotate, and the first connecting rod will pull the slide rod to move away from the connecting hose. Simultaneously, the second connecting rod, the connecting frame and the sealing ring will move until the right side of the sealing ring in the middle contacts the limit frame, making the sealing ring flush with the connecting hole. Since the sealing ring is blocked, it cannot move horizontally. The slide rod will then pull the second connecting rod to rotate, causing the second connecting rod to push the connecting frame and the sealing ring to rise, allowing the sealing ring to enter the connecting hole and seal the connecting hole again. After the operator removes the finished workpiece, the surface of the machining table is blew with an external air gun to remove debris and cutting fluid. The connecting hole is sealed with a sealing ring to prevent debris from contacting the suction cup. This effectively prevents debris from adhering to the inside of the suction cup when cleaning the top of the machining table, which would affect the tight fit between the suction cup and the workpiece. This ensures stable suction cup clamping force and smooth operation of milling.

[0011] Preferably, the extrusion assembly includes several inclined connecting plates slidably connected to the inner wall of the processing table, and several spring rods slidably connected to the top of the processing table; The top of several inclined connecting plates near the electric telescopic rod is fixedly connected to the bottom of the negative pressure frame; When the negative pressure frame rises, it will drive the inclined connecting plate to rise. As the inclined connecting plate continues to move, the inclined surface of the inclined connecting plate will come into contact with the spring rod, thereby squeezing the spring rod to move and allowing the spring rod to accumulate rebound force under pressure.

[0012] Preferably, the clamping assembly includes a plurality of sliding plates slidably connected to the inner wall of the positioning frame, and a plurality of spring pressure plates slidably connected to the inner wall of the positioning frame; The outer walls of several spring pressure plates are slidably connected to the inner walls of several sliding plates, and the side of several sliding plates away from the spring pressure plates is fixedly connected to the side of several spring rods close to the spring pressure plates. When the spring rod moves, it drives the slide plate to move, causing the slide plate to squeeze the spring of the spring pressure plate. This causes the spring of the spring pressure plate to accumulate rebound force, which in turn squeezes the workpiece placed in the positioning frame, pre-compressing the workpiece. When the suction cup rises past the top of the processing table and continues to adhere to the bottom of the workpiece, the suction cup cannot push the workpiece upward, allowing the suction cup to fully deform and adhere tightly to the bottom of the workpiece. This effectively prevents the workpiece bottom from having excessive flatness. If the suction cup is flush with the top of the processing table, some suction cups will have poor contact, affecting the effective formation of vacuum and causing insufficient suction force. By pre-extruding and fixing the workpiece position, the workpiece can be attached to the top of the processing table, providing sufficient support for the workpiece. This effectively prevents the workpiece from being lifted up when the suction cup rises over the top of the processing table and attaches to the bottom of the workpiece, as the workpiece is relatively light and will affect the support of the processing table for the workpiece, making it difficult to withstand the cutting force during milling. By creating an annular groove around the connecting hole, when milling the workpiece, some of the cutting fluid used in the milling process will penetrate between the bottom of the workpiece and the top of the machining table, and gradually flow towards the connecting hole. The cutting fluid will first flow into the annular groove, and through the guidance of the annular groove, the penetrated cutting fluid will be continuously discharged, effectively preventing the cutting fluid from penetrating into the bottom of the workpiece and contacting the outer surface of the suction cup during the cutting process, which would contaminate the outer surface of the suction cup. Long-term adhesion of cutting fluid will cause the suction cup to harden and reduce its deformation capacity.

[0013] A manufacturing process for a full milling production apparatus for laptop casings includes the following steps: S1: Workpiece installation: The operator places the aluminum alloy profile workpiece to be processed into the positioning frame. After placement, the electric telescopic rod is extended, pushing the negative pressure frame and suction cup to rise. The negative pressure frame will push the connecting rod to rotate. S2: Unsealing and lowering: Link 1 pushes the slide bar to move towards the connecting hose, the slide bar will push link 2 to rotate, and link 2 will pull the connecting frame and sealing ring down; S3: Unsealing and opening: As the sealing ring continues to descend, it will separate from the connecting hole, the vertical limit on the sealing ring will disappear, and the sealing ring will be subject to the horizontal lateral limit of the limit frame.

[0014] The present invention has the following beneficial effects: This invention involves placing the workpiece within a positioning frame, extending the electric telescopic rod to raise the negative pressure frame and suction cup. Through the pushing and sealing components, the connecting hole is opened, allowing the suction cup to adhere to the bottom of the workpiece. The workpiece is then firmly held in place by the suction cup. The CNC milling machine body is then activated to mill the workpiece. After milling, the electric telescopic rod retracts, causing the negative pressure frame and suction cup to descend. The connecting hole is then sealed again by the pushing and sealing components. After the operator removes the finished workpiece, an external air gun is used to blow away debris from the machining table surface, preventing it from contacting the suction cup. This effectively prevents debris from adhering to the suction cup during cleaning of the top of the machining table, thus ensuring stable suction cup clamping force and smooth milling operation.

[0015] (2) In this invention, when the negative pressure frame rises, it will drive the inclined connecting plate to rise. As the inclined connecting plate continues to move, the inclined surface of the inclined connecting plate will contact the spring rod, thereby squeezing the spring rod to move towards the spring pressure plate, pushing the slide plate to move, and letting the slide plate squeeze the spring of the spring pressure plate. Through the spring's rebound force, the spring pressure plate pre-squeezes the workpiece. When the suction cup rises past the top of the processing table and continues to adhere to the bottom of the workpiece, the suction cup cannot push the workpiece to rise, so that the suction cup can fully deform and adhere tightly to the bottom of the workpiece, effectively preventing the workpiece bottom from having excessive flatness. When the suction cup is flush with the top of the processing table, some suction cups will have poor contact, affecting the effective formation of vacuum and causing insufficient adsorption force.

[0016] (3) In this invention, by pre-extruding and fixing the position of the workpiece, the workpiece can be attached to the top of the processing table, providing sufficient support for the workpiece. This effectively prevents the workpiece from being lifted up when the suction cup rises above the top of the processing table and attaches to the bottom of the workpiece, affecting the support of the processing table for the workpiece and making it difficult to withstand the cutting force during milling. In addition, by placing the top of the sealing ring lower than the top of the processing table, the bottom of the workpiece will not contact the sealing ring each time the workpiece is placed, keeping the workpiece position at the top of the sealing ring clean. This effectively prevents a small amount of cutting fluid from remaining on the top of the sealing ring after purging, which will adhere to the bottom of the workpiece. When the suction cup contacts the workpiece, the cutting fluid will adhere to the suction cup, forming a liquid film, reducing the friction of the contact surface and affecting the clamping reliability.

[0017] (4) In this invention, an annular groove is provided around the connecting hole. When the workpiece is milled, some of the cutting fluid used in the milling process will penetrate between the bottom of the workpiece and the top of the processing table and gradually flow towards the connecting hole. The cutting fluid will first flow into the annular groove. Through the guidance of the annular groove, the penetrated cutting fluid will be continuously discharged, which effectively prevents the cutting fluid from penetrating into the bottom of the workpiece and contacting the outer surface of the suction cup during the cutting process, which will contaminate the outer surface of the suction cup. If the cutting fluid adheres for a long time, it will cause the suction cup to harden and reduce the deformation capacity of the suction cup. Attached Figure Description

[0021] 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.

[0022] Example 1, please refer to Figures 1-5 This invention relates to a full milling production device for laptop casings, comprising a CNC milling machine body 13, a machining table 14 fixedly connected to the bottom of the inner wall of the CNC milling machine body 13, a positioning frame 15 fixedly connected to the top of the machining table 14, and further comprising: Fixing mechanism 1 is installed on the inner wall of the processing table 14. Fixing mechanism 1 includes a plurality of limiting frames 101 installed on the inner wall of the processing table 14. The shielding mechanism 2 is installed on the inner wall of the processing table 14. The shielding mechanism 2 includes a plurality of connecting brackets 201 installed on the inner wall of the processing table 14. The limiting mechanism 3 is installed on the top of the processing table 14. The limiting mechanism 3 includes several annular inclined grooves 301 formed on the top of the processing table 14. There are two limit frames 101, two connecting frames 201, and six annular inclined grooves 301. When in use, the operator places the aluminum alloy profile workpiece to be processed in the positioning frame 15, and then fixes the workpiece by the fixing mechanism 1. After the fixing is completed, the CNC milling machine body 13 is started to mill the workpiece.

[0023] Fixed mechanism 1 also includes: Adsorption component 11 is installed on the inner wall of the processing table 14; Drive component 12 is installed on the inner wall of adsorption component 11.

[0024] The shielding mechanism 2 also includes: Push component 21 is installed on top of adsorption component 11; The sealing component 22 is installed on the inner wall of the processing table 14.

[0025] The limiting mechanism 3 also includes: Extrusion assembly 31 is installed on the inner wall of processing table 14; The clamping component 32 is installed on the inner wall of the positioning frame 15.

[0026] Example 2, please refer to Figures 3-12The present invention is a full milling production device for laptop shells. Based on the first embodiment, the adsorption component 11 includes a sliding groove 111 opened on the inner wall of the processing table 14, and the tops of several limiting frames 101 are fixedly connected to the top of the inner wall of the sliding groove 111. A negative pressure frame 112 is slidably connected to the inner wall of the sliding groove 111, and several suction cups 113 are fixedly connected to the top of the negative pressure frame 112. The drive assembly 12 includes an electric telescopic rod 121 fixedly connected to the bottom of the inner wall of the sliding groove 111. The top of the output end of the electric telescopic rod 121 is fixedly connected to the bottom of the negative pressure frame 112. A connecting hose 122 is connected through the inner wall of the negative pressure frame 112. The suction cups 113 are provided with six cups. The connecting hose 122 is connected to an external vacuum pump. After the workpiece is placed in place, the electric telescopic rod 121 is activated to extend and push the negative pressure frame 112 and the suction cups 113 to rise.

[0027] The pushing component 21 includes several connecting rods 211 rotatably connected to the top of the negative pressure frame 112, and several sliding rods 212 slidably connected to the top of the inner wall of the sliding groove 111; The top inner walls of several connecting rods 211 are rotatably connected to the side of several sliding rods 212 away from the connecting hose 122, and connecting rods 213 are rotatably connected to the side of several sliding rods 212 near the connecting hose 122. The bottom inner walls of several connecting rods 213 are rotatably connected to the side of several connecting frames 201 away from the annular inclined groove 301; There are two connecting rods 211, two sliding rods 212, and two connecting rods 213. The negative pressure frame 112 will push the connecting rods 211 to rotate, causing the connecting rods 211 to push the sliding rods 212 to move towards the connecting hose 122. The sliding rods 212 will push the connecting rods 213 to rotate, and the connecting frame 201 will be pulled down by the connecting rods 213.

[0028] The sealing assembly 22 includes several connecting holes 221 opened on the top of the processing table 14, and the inner walls of the several connecting holes 221 are slidably connected with sealing rings 222. The bottom of several sealing rings 222 is fixedly connected to the top of several connecting frames 201, and the outer wall of several sealing rings 222 is slidably connected to the inner wall of several limiting frames 101. In this configuration, a number of sealing rings 222 are fixedly connected to the outer walls of the sealing rings 222. There are six connecting holes 221 and six sealing rings 222. The top of a connecting frame 201 is fixed to three sealing rings 222. The three sealing rings 222 slide on the inner wall of a limiting frame 101. As the sealing rings 222 continue to descend, they will separate from the connecting holes 221. The vertical limitation on the sealing rings 222 will disappear, and the sealing rings 222 will be subject to the horizontal limitation of the limiting frame 101. At this time, the slide bar 212 continues to move towards the connecting hose 122, which will drive the connecting rod 213, the connecting frame 201 and the sealing ring 222 to move synchronously, so that the sealing ring 222 moves away from the connecting hole 221 and opens the connecting hole 221. As the suction cup 113 continues to move, the suction cup 113 will move into the connecting hole 221, so that the suction cup 113 is attached to the bottom of the workpiece. Then the external vacuum pump is started, and a vacuum negative pressure is formed in the negative pressure frame 112 through the connecting hose 122. The workpiece is tightly adsorbed and fixed by the suction cup 113. After the fixation is completed, the CNC milling machine body 13 is started to mill the workpiece. After processing, the external vacuum pump is restarted to eliminate the vacuum negative pressure inside the negative pressure frame 112, thus releasing the workpiece from its fixation. Then, the electric telescopic rod 121 is retracted, causing the negative pressure frame 112 and suction cup 113 to descend. The negative pressure frame 112 pulls the connecting rod 211 to rotate, which in turn pulls the sliding rod 212 away from the connecting hose 122. Simultaneously, this moves the connecting rod 213, connecting frame 201, and sealing ring 222 until the right side of the sealing ring 222 in the middle contacts the limiting frame 101. Figure 7 As shown in the position of G, the sealing ring 222 is aligned with the connecting hole 221. Since the sealing ring 222 is blocked and cannot move horizontally, the slide rod 212 will pull the connecting rod 213 to rotate, causing the connecting rod 213 to push the connecting frame 201 and the sealing ring 222 to rise, allowing the sealing ring 222 to enter the connecting hole 221 and seal the connecting hole 221 again. After the operator removes the finished workpiece, the surface of the machining table 14 is blew clean with an external air gun to remove debris and cutting fluid. The connecting hole 221 is sealed by the sealing ring 222, making it difficult for debris to come into contact with the suction cup 113. This effectively prevents debris from adhering to the inside of the suction cup 113 when cleaning the top of the machining table 14, which would affect the tight fit between the suction cup 113 and the workpiece. This ensures the stable clamping force of the suction cup 113 and guarantees the smooth operation of the milling process.

[0029] The extrusion assembly 31 includes several inclined connecting plates 311 that are slidably connected to the inner wall of the processing table 14, and several spring rods 312 that are slidably connected to the top of the processing table 14. The top of several inclined connecting plates 311 near the electric telescopic rod 121 is fixedly connected to the bottom of the negative pressure frame 112; There are two inclined connecting plates 311 and two spring rods 312. When the negative pressure frame 112 rises, it will drive the inclined connecting plates 311 to rise. As the inclined connecting plates 311 continue to move, the inclined surface of the inclined connecting plates 311 will contact the spring rods 312, thereby squeezing the spring rods 312 to move, so that the spring rods 312 are compressed and accumulate rebound force.

[0030] The clamping assembly 32 includes a plurality of sliding plates 321 slidably connected to the inner wall of the positioning frame 15, and a plurality of spring pressure plates 322 slidably connected to the inner wall of the positioning frame 15. The outer walls of several spring pressure plates 322 are slidably connected to the inner walls of several sliding plates 321, and the side of several sliding plates 321 away from the spring pressure plates 322 is fixedly connected to the side of several spring rods 312 close to the spring pressure plates 322. There are two sliding plates 321 and two spring pressure plates 322. When the spring rod 312 moves, it will drive the sliding plate 321 to move, so that the sliding plate 321 squeezes the spring of the spring pressure plate 322, so that the spring of the spring pressure plate 322 accumulates rebound force. The spring pressure plate 322 will then squeeze the workpiece placed in the positioning frame 15 to pre-compress the workpiece. When the suction cup 113 rises over the top of the processing table 14 and continues to stick to the bottom of the workpiece, the suction cup 113 cannot push the workpiece to rise, so that the suction cup 113 can fully deform and stick tightly to the bottom of the workpiece, effectively preventing the bottom of the workpiece from having excessive flatness. When the suction cup 113 is flush with the top of the processing table 14, some suction cups 113 will have poor contact, affecting the effective formation of vacuum and causing insufficient adsorption force. By pre-extruding and fixing the workpiece position, the workpiece can be attached to the top of the processing table 14, providing sufficient support for the workpiece. This effectively prevents the suction cup 113 from rising over the top of the processing table 14 and attaching to the bottom of the workpiece. Due to the light weight of the workpiece, it would lift the workpiece, affecting the support of the processing table 14 for the workpiece and making it difficult to withstand the cutting force during milling. By providing an annular groove 301 around the connecting hole 221, when milling the workpiece, some of the cutting fluid used in the milling process will penetrate between the bottom of the workpiece and the top of the machining table 14, and gradually flow towards the connecting hole 221. The cutting fluid will first flow into the annular groove 301, and through the guidance of the annular groove 301, the penetrated cutting fluid will be continuously discharged, effectively preventing the cutting fluid from penetrating into the bottom of the workpiece and contacting the outer surface of the suction cup 113 during the cutting process, which would contaminate the outer surface of the suction cup 113. Long-term adhesion of cutting fluid will cause the suction cup 113 to harden and reduce the deformation capacity of the suction cup 113.

[0031] The number of the above structures is not limited. Those skilled in the art can freely set them according to actual needs, as long as the above structures are installed at the connection positions of the corresponding structures.

[0032] The method of using this full milling production equipment for laptop casings includes the following steps: S1: Workpiece installation: The operator places the aluminum alloy profile workpiece to be processed into the positioning frame 15. After placement, the electric telescopic rod 121 is activated to extend, pushing the negative pressure frame 112 and suction cup 113 to rise. The negative pressure frame 112 will push the connecting rod 211 to rotate. S2: Unsealing and lowering: Link 1 211 pushes slide 212 toward connecting hose 122, slide 212 will push link 213 to rotate, and link 213 will pull connecting frame 201 and sealing ring 222 down; S3: Unsealing and opening: As the sealing ring 222 continues to descend, the sealing ring 222 will separate from the connecting hole 221, the vertical limit on the sealing ring 222 will disappear, and the sealing ring 222 will be subject to the horizontal limit of the limit frame 101.

[0033] A specific application of this embodiment is as follows: When using this invention, the connecting hose 122 is connected to an external vacuum pump. The operator places the aluminum alloy profile workpiece to be processed in the positioning frame 15. After placement, the electric telescopic rod 121 is extended, pushing the negative pressure frame 112 and the suction cup 113 to rise. The negative pressure frame 112 will push the connecting rod 1 211 to rotate, causing the connecting rod 1 211 to push the slide rod 212 to move towards the connecting hose 122. The slide rod 212 will push the connecting rod 213 to rotate, and the connecting rod 213 will pull the connecting frame 201 and the sealing ring 222 to descend. As the sealing ring 222 continues to descend, the sealing ring 222 will separate from the connecting hole 221, and the vertical limitation on the sealing ring 222 will disappear. The sealing ring 222 will be subject to the horizontal lateral limitation of the limiting frame 101. At this time, the slide bar 212 continues to move towards the connecting hose 122, which will drive the connecting rod 213, the connecting frame 201 and the sealing ring 222 to move synchronously, so that the sealing ring 222 moves away from the connecting hole 221 and opens the connecting hole 221. As the suction cup 113 continues to move, the suction cup 113 will move into the connecting hole 221, so that the suction cup 113 is attached to the bottom of the workpiece. Then the external vacuum pump is started, and a vacuum negative pressure is formed in the negative pressure frame 112 through the connecting hose 122. The workpiece is tightly adsorbed and fixed by the suction cup 113. After the fixation is completed, the CNC milling machine body 13 is started to mill the workpiece. After processing, the external vacuum pump is restarted to eliminate the vacuum negative pressure inside the negative pressure frame 112, thus releasing the workpiece from its fixation. Then, the electric telescopic rod 121 is retracted, causing the negative pressure frame 112 and suction cup 113 to descend. The negative pressure frame 112 pulls the connecting rod 211 to rotate, which in turn pulls the sliding rod 212 away from the connecting hose 122. Simultaneously, this moves the connecting rod 213, connecting frame 201, and sealing ring 222 until the right side of the sealing ring 222 in the middle contacts the limiting frame 101. Figure 7 As shown in the position of G, the sealing ring 222 is aligned with the connecting hole 221. Since the sealing ring 222 is blocked and cannot move horizontally, the slide rod 212 will pull the connecting rod 213 to rotate, causing the connecting rod 213 to push the connecting frame 201 and the sealing ring 222 to rise, allowing the sealing ring 222 to enter the connecting hole 221 and seal the connecting hole 221 again. After the operator removes the finished workpiece, the surface of the machining table 14 is blew with an external air gun to remove debris and cutting fluid. The connecting hole 221 is sealed with a sealing ring 222 to prevent debris from contacting the suction cup 113. This effectively prevents debris from adhering to the inside of the suction cup 113 when cleaning the top of the machining table 14, which would affect the tight fit between the suction cup 113 and the workpiece. This ensures the stable clamping force of the suction cup 113 and guarantees the smooth operation of the milling process. When the negative pressure frame 112 rises, it will drive the inclined connecting plate 311 to rise. As the inclined connecting plate 311 continues to move, the inclined surface of the inclined connecting plate 311 will contact the spring rod 312, thereby squeezing the spring rod 312 to move towards the spring pressure plate 322, so that the spring rod 312 is compressed and accumulates rebound force. The spring rod 312 will push the slide plate 321 to move, so that the slide plate 321 squeezes the spring of the spring pressure plate 322, so that the spring of the spring pressure plate 322 accumulates rebound force. The spring pressure plate 322 will squeeze the workpiece placed in the positioning frame 15 to pre-compress the workpiece. When the suction cup 113 rises over the top of the processing table 14 and continues to adhere to the bottom of the workpiece, the suction cup 113 cannot push the workpiece to rise, so that the suction cup 113 can fully deform and adhere tightly to the bottom of the workpiece, effectively preventing the workpiece bottom from having excessive flatness. When the suction cup 113 is flush with the top of the processing table 14, some suction cups 113 will have poor contact, affecting the effective formation of vacuum and causing insufficient adsorption force. By pre-extruding and fixing the workpiece position, the workpiece can be attached to the top of the processing table 14, providing sufficient support for the workpiece. This effectively prevents the suction cup 113 from rising over the top of the processing table 14 and attaching to the bottom of the workpiece. Due to the light weight of the workpiece, it would lift the workpiece, affecting the support of the processing table 14 for the workpiece and making it difficult to withstand the cutting force during milling. In addition, by positioning the top of the sealing ring 222 lower than the top of the machining table 14, the bottom of the workpiece will not come into contact with the sealing ring 222 each time it is placed, keeping the workpiece position at the top of the sealing ring 222 clean. This effectively prevents a small amount of cutting fluid from remaining on the top of the sealing ring 222 after purging, which would then adhere to the bottom of the workpiece. When the suction cup 113 comes into contact with the workpiece, the cutting fluid would adhere to the suction cup 113, forming a liquid film, which would reduce the friction of the contact surface and affect the reliability of clamping. By providing an annular groove 301 around the connecting hole 221, when milling the workpiece, some of the cutting fluid used in the milling process will penetrate between the bottom of the workpiece and the top of the machining table 14, and gradually flow towards the connecting hole 221. The cutting fluid will first flow into the annular groove 301, and through the guidance of the annular groove 301, the penetrated cutting fluid will be continuously discharged, effectively preventing the cutting fluid from penetrating into the bottom of the workpiece and contacting the outer surface of the suction cup 113 during the cutting process, which would contaminate the outer surface of the suction cup 113. Long-term adhesion of cutting fluid will cause the suction cup 113 to harden and reduce the deformation capacity of the suction cup 113.
