A processing system for 3D printing of engine integral blade disk

Abstract

The present invention is applicable to the technical field of engine integral blade discs, and provides a processing system for 3D printing of engine integral blade discs, including a main body component, a grabbing component installed on the internal top wall of the main body component, and a flip component and a second trimming component installed on the internal bottom wall of the main body component. The flip component and the second trimming component are arranged in parallel. The device solves the problem that the 3D printed blade disc has a complex structure and a narrow and irregular internal space, resulting in residual unmelted particles and difficulty in thorough cleaning through conventional vacuuming, which affects the subsequent processing quality and blade disc performance. The device is provided with a first trimming component, and uses multiple groups of rollers to go deep into the gap between blades of the blade disc to clean the unmelted particles on the side wall. The driving motor drives the gear to rotate, so that the roller moves around and fits the side wall of the blade. At the same time, the pneumatic chuck drives the roller to move along the blade to clean a large area. The roller can adapt to the bending of the blade and swing for cleaning to ensure the cleaning effect.

Description

Technical Field

[0001] The present invention relates to the technical field of engine integral blade disks, and more specifically, to a processing system for 3D printing of engine integral blade disks. Background Art

[0002] The engine blisk is a structural component that integrates the engine rotor blades and the wheel disc. It is designed to meet the needs of high-performance engines. It eliminates the tenons, mortise and tenon grooves and locking devices in traditional connections, thus simplifying the engine structure.

[0003] At present, the existing leaf discs require workers to clean them directly with a brush and a vacuum cleaner after printing. This method will cause the printing equipment to be occupied and unusable. For this reason, the staff designed a processing equipment, that is, the leaf disc and the supporting base are directly transferred to the equipment, and then the leaf disc is flipped through the flipping mechanism, a large amount of powder is poured out, and then the staff manually cleans the remaining powder.

[0004] However, since the blade disc is processed by 3D printing technology, the printed blade disc is bonded to the base, and the internal structure of the blade disc is relatively complex, and the space between adjacent blades is relatively narrow and irregular. In this case, some unmelted particles will remain in it. Conventional vacuuming methods are used to clean these particles, but due to the particularity of the internal space of the blade disc, especially those unmelted particles in dead corners, conventional vacuuming equipment is difficult to penetrate into these areas and cannot clean them thoroughly. This may not only affect the subsequent processing quality of the blade disc, but may also have potential adverse effects on its performance during the use of the blade disc. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a processing system for 3D printing of an engine integral blade disk.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a processing system for 3D printing of an integral engine blade disk, comprising a main body component, a grabbing component installed on the top wall inside the main body component, and a flipping component and a second trimming component installed on the bottom wall inside the main body component, the flipping component and the second trimming component are arranged in parallel, a base is arranged inside the flipping component, a blade disk is arranged on the top of the base, a cutting component is arranged on one side of the flipping component and located on one side of the blade disk, a first trimming component is installed on the bottom of the grabbing component, and the first trimming component is located above the flipping component and the second trimming component.

[0007] The main body assembly comprises a box body and a frame installed inside the box body.

[0008] The first trimming component includes a lifting cylinder installed at the bottom of the grabbing component and a pneumatic chuck connected to the end of the piston rod of the lifting cylinder. The bottom of the pneumatic chuck is equidistantly slidably connected with multiple groups of moving blocks. A connecting block is installed at the bottom of each moving block. The bottom of the connecting block is horizontally connected to a carrying plate. The bottom of the carrying plate is rotatably connected to two driven gears, and the two driven gears are meshed. Connecting platforms are horizontally arranged on the outer walls of the two driven gears. A first trimming motor is installed on the top of the connecting platform. The output end of the first trimming motor passes through the corresponding connecting platform and is connected to a roller. A driving motor is installed at the bottom of the carrying plate. The output end of the driving motor is connected to a driving gear, and the driving gear is meshed with one of the driven gears.

[0009] A rotating shaft is horizontally connected to one side of each connecting platform close to the corresponding driven gear, and one end of the rotating shaft away from the connecting platform is rotatably connected to the outer wall of the corresponding driven gear. A torsion spring is provided on the outer wall of the rotating shaft, and the two ends of the torsion spring are respectively connected to the corresponding side wall of the connecting platform and the outer wall of the driven gear. A telescopic rod is installed on the top of the connecting platform, and a positioning hole is opened on the outer wall of the driven gear. The size of the positioning hole is adapted to the size of the piston rod end of the telescopic rod.

[0010] The present invention is further configured as follows: a plurality of grooves are formed around and equidistantly on the outer side wall of the rotating roller, a scraping block is inserted into each of the grooves, and a spring is connected between the scraping block and the inner wall of the corresponding groove.

[0011] The present invention is further configured as follows: the grabbing assembly includes two groups of first connecting rods installed on the inner top wall of the frame, each of the first connecting rods is slidably connected to an electric transfer block, a second connecting rod is connected between the two electric transfer blocks, the outer side wall of the second connecting rod is slidably connected to a rotating cylinder, and the first trimming assembly is installed at the bottom of the rotating cylinder.

[0012] By adopting the above technical solution, when the first trimming component moves to the top of the blade disk, the pneumatic chuck and the moving block are driven to move downward as a whole by the lifting cylinder. During this process, the pneumatic chuck drives multiple moving blocks to separate at equal distances, and the connecting blocks installed on the moving blocks and the various components connected to the bottom of the connecting blocks move synchronously. The two rollers corresponding to each connecting block extend downward to the gap between the two blades on the blade disk. The first trimming motor drives the corresponding rollers to rotate, and the rollers clean the adhered unmelted particles on the side walls of the blades.

[0013] During the process of cleaning the side wall of the blade, the roller drives the driving gear to rotate through the driving motor, and the driving gear drives one of the driven gears to rotate. The two driven gears mesh with each other and rotate, thereby driving the rotating shaft connected to the driven gear and the connecting platform to move in a circular motion. The connecting platform drives the corresponding first trimming motor and the roller to move synchronously, and the two corresponding rollers separate from each other and fit with the adjacent side walls of the two blades, so that while the roller cleans the unmelted particles on the side wall of the blade, the pneumatic chuck drives the moving block and the connecting block to move, so that the roller moves along the side wall of the blade, and the unmelted particles on the side wall of the blade are cleaned over a large area.

[0014] During the movement, the roller is affected by the blade angle and swings, driving the corresponding shaft to rotate, and the corresponding torsion spring twists and rotates. During this process, the roller can adapt to the curved blades to achieve the purpose of adaptive swinging and cleaning of the curved blades. When the roller is not affected by the blade angle, the torsion force of the torsion spring drives the connecting platform to reset until the roller cleans all positions on the inner wall of the blade. When the first trimming component cleans the same number of particles in the gaps between blades, the grabbing component is used to drive the first trimming component to rotate as a whole through an angle of a blade gap, and then the particle cleaning operation is performed again, and this process is repeated until all the blade side walls are cleaned.

[0015] The present invention is further configured as follows: the flip assembly includes a support plate installed on the inner bottom wall of the frame and a mounting seat horizontally connected to the top of the support plate, a servo motor mechanism is installed on the top of the mounting seat, the output end of the servo motor mechanism is connected to the first vertical plate, a horizontal plate is arranged at the bottom of the first vertical plate, two slides are arranged on the top of the horizontal plate, one of the slides is fixedly connected to the horizontal plate, and the other slide is slidably connected to the top of the horizontal plate, the bottom of the first vertical plate is connected to the top of one of the fixedly connected slides, and the top of the other slidably connected slide is connected to a fixed plate and a second vertical plate, a support rod is penetrated and slidably connected to the top of the fixed plate and the second vertical plate, one end of the support rod is connected to the inner side wall of the frame, and the base and the leaf disk are arranged between the first vertical plate and the second vertical plate.

[0016] The present invention is further configured as follows: a driving cylinder is horizontally arranged on the side wall of the horizontal plate, the piston rod and the cylinder housing of the driving cylinder are respectively connected to the two slides, an L-shaped plate is connected to the side wall of the second vertical plate, a side of the L-shaped plate away from the second vertical plate is horizontally connected to a limiting rod, a side of the first vertical plate away from the servo motor mechanism is horizontally connected to a placing plate, and the limiting rod is inserted into the inside of the placing plate.

[0017] By adopting the above technical solution, the servo motor mechanism is composed of a servo motor and a reducer. The output end of the servo motor mechanism is connected to the first vertical plate. The servo motor transmits the driving force to the reducer. The reducer converts the driving force and then applies it to the first vertical plate. When the first vertical plate rotates, it drives the slide, the cross plate, the fixed plate and the second vertical plate to rotate, and then drives the base to rotate to pour out the residual powder. After that, the angle of the base and the blade disk is adjusted to the angle to be processed. Since the base and the blade disk may fall when rotating, when the base and the blade disk are placed on the top of the placement plate, the piston rod of the driving cylinder contracts, causing the two slides to approach each other. One of the slides slidably connected to the cross plate drives the fixed plate and the second vertical plate to slide on the outer wall of the support rod. The second vertical plate drives the L-shaped plate and the limit rod to move synchronously, and the limit rod gradually slides into the interior of the placement plate. During this process, the first vertical plate and the second vertical plate cooperate to clamp and fix the base to prevent the base and the blade disk from falling during subsequent flipping.

[0018] The present invention is further configured as follows: the cutting assembly includes mounting plates symmetrically installed on both sides of the first vertical plate, a guide rod is horizontally connected between the two mounting plates, a slider is slidably connected to the outer wall of the guide rod, and the bottom of the slider is flush with the top of the base.

[0019] The present invention is further configured as follows: the second trimming assembly includes a fixing seat installed on the inner bottom wall of the frame, and a processing mechanism is installed on the top of the fixing seat.

[0020] The present invention is further configured as follows: the processing mechanism comprises a second trimming motor installed on the top of the fixing seat, and a rotating disk is horizontally installed on the top of the output end of the second trimming motor.

[0021] The present invention is further configured as follows: a plurality of circles of trimming columns are equidistantly arranged around the top of the turntable, the protrusions between the trimming columns in each circle are staggered, a scraper strip is installed on the top of the turntable, and the scraper strip extends from the center of the turntable to the edge.

[0022] By adopting the above technical solution, when all the blades of the leaf disk are cleaned, the roller moves to the position where the blades are close to the center of the leaf disk, the drive motor stops running, the roller clamps the leaf disk, and then the leaf disk is cut by the cutting assembly to separate the base and the leaf disk, and the leaf disk is lifted and displaced by the grabbing assembly and the first trimming assembly. After the leaf disk moves to the top of the turntable and fits with the top of the turntable, the turntable is driven to rotate by the second trimming motor, so that the trimming column and the scraper strip cooperate to clean the unmelted particles at the bottom of the leaf disk, that is, the trimming column grinds the unmelted particles at the bottom of the leaf disk into powder, and the scraper strip scrapes off the powder or partially unmelted particles adhering to the bottom of the leaf disk. After the leaf disk is cleaned, the grabbing assembly can remove the leaf disk.

[0023] The specific working steps of a processing system for 3D printing of an engine blisk are as follows:

[0024] S1. The staff places the base and blade disc to be processed on the top of the flip assembly, and then adjusts the angle of the base and blade disc to the angle to be processed through the flip assembly, and the remaining powder is poured out.

[0025] S2, control the first trimming assembly to move to the top of the blade disk through the grabbing assembly, and then drive the pneumatic chuck and the moving block to move downward as a whole through the lifting cylinder. During this process, the pneumatic chuck drives the multiple moving blocks to separate at equal distances, and the connecting blocks installed on the moving blocks and the various components connected to the bottom of the connecting blocks move synchronously. The two rollers corresponding to each connecting block extend downward to the gap between the two blades on the blade disk, and the first trimming motor drives the corresponding rollers to rotate, and the rollers clean the unmelted particles on the side walls of the blades.

[0026] S3. When the roller is cleaning the side wall of the blade, the driving motor drives the driving gear to rotate, and the driving gear drives one of the driven gears to rotate. The two driven gears mesh with each other and rotate, thereby driving the rotating shaft connected to the driven gear and the connecting platform to move in a circular motion. The connecting platform drives the corresponding first trimming motor and the roller to move synchronously. The two corresponding rollers separate from each other and fit with the adjacent side walls of the two blades, so that while the roller is cleaning the unmelted particles on the side wall of the blade, the pneumatic chuck drives the moving block and the connecting block to move, so that the roller moves along the side wall of the blade, and the unmelted particles on the side wall of the blade are cleaned over a large area.

[0027] S4. During the movement, the roller is affected by the blade angle and swings, driving the corresponding shaft to rotate. At the same time, the corresponding torsion spring twists and rotates. When the roller is not affected by the blade angle, the torsion force of the torsion spring drives the connecting platform to reset until the roller cleans all positions on the inner wall of the blade. When the first trimming component cleans the same number of particles in the gaps between the blades, the grabbing component is used to drive the first trimming component to rotate as a whole by an angle of a blade gap, and then the particle cleaning operation is performed again through the above steps, and this process is repeated until all the side walls of the blades are cleaned.

[0028] S5. When all blades of the leaf disk are cleaned, the roller moves to a position where the blade is close to the center of the leaf disk, the drive motor stops running, the roller clamps the leaf disk, and then the leaf disk is cut by the cutting assembly to separate the base and the leaf disk, and the leaf disk is lifted and displaced by the grabbing assembly and the first trimming assembly;

[0029] S6. The leaf disc is moved to the top of the second trimming assembly. The bottom of the leaf disc is cleaned by the second trimming assembly. After the cleaning is completed, the grabbing assembly can move the leaf disc out.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] By setting the first trimming component, multiple groups of rollers extend to multiple blade gaps in the blade disk at the same time, and the side walls of the blades are cleaned by the rollers. The driving motor drives the driving gear to rotate, and the driving gear drives one of the driven gears to rotate. The two driven gears mesh and rotate with each other, thereby driving the rotating shaft connected to the driven gear and the connecting platform to move in a circular motion. The connecting platform drives the corresponding first trimming motor and rollers to move synchronously, and the two corresponding rollers separate from each other and fit with the adjacent side walls of the two blades. As a result, while the rollers clean the unmelted particles on the side walls of the blades, the pneumatic chuck drives the moving block and the connecting block to move, so that the rollers move along the side walls of the blades, and the unmelted particles on the side walls of the blades are cleaned over a large area.

[0032] By setting a scraper block and a rotating shaft, the roller swings under the influence of the blade angle during movement and drives the corresponding rotating shaft to rotate. At the same time, the corresponding torsion spring twists and rotates. In this process, the roller can adapt to the curved blades to achieve the purpose of adaptive swinging cleaning of the curved blades.

[0033] By setting a scraping block, when the roller cleans the side wall of the blade, the scraping block is squeezed to shrink into the corresponding groove and squeeze the spring sheet. When the roller moves to the dead angle position of the blade, the reaction force of the spring sheet pushes the corresponding scraping block out. The scraping block extends to the dead angle position of the blade and is not restricted by the squeezing of the inner wall of the blade. The roller drives multiple scraping blocks to rotate synchronously, thereby achieving the purpose of cleaning the dead angle position of the blade. When the roller cleans the inner wall of the blade, the multiple scraping blocks on the outer wall of the roller will adapt to the different bending angles of the inner wall of the blade, thereby meeting the purpose of adaptive cleaning of the inner wall of the blade.

[0034] When the blades of the blisk are cleaned, there is no need to manually move the blisk. The blisk and the base can be separated by using the cutting assembly, and then the blisk can be grabbed by the first trimming assembly and placed on the top of the turntable for secondary trimming.

[0055] See also Figure 1-Figure 11 , the present invention provides the following technical solutions:

[0056] Embodiment 1, a processing system for 3D printing of an integral engine blade disk, includes a main component 1, the main component 1 includes a box body 11 and a frame 12 installed inside the box body 11, the box body 11 and the frame 12 cooperate to form a processing cavity, which is convenient for subsequent processing operations.

[0057] See also Figure 1-Figure 2 and Figure 5 A flip assembly 3 is installed on the inner bottom wall of the frame 12, a base 7 is arranged inside the flip assembly 3, a leaf disc 8 is arranged on the top of the base 7, the base 7 is used to support the leaf disc 8, and the leaf disc 8 is bonded to the base 7. When the leaf disc 8 and the base 7 remain bonded, the flip assembly 3 supports the base 7 and the leaf disc 8, and a small amount of powder will exist when the base 7 and the leaf disc 8 are taken out of the printing device. Therefore, when the base 7 and the leaf disc 8 are placed inside the frame 12, the flip assembly 3 is used to flip the base 7 and the leaf disc 8, so that a small amount of powder is poured out.

[0058] See also Figure 4 and Figure 5 , the specific structure of the flip component 3 is as follows:

[0059] In this embodiment, the flip assembly 3 includes a support plate 31 installed on the inner bottom wall of the frame 12 and a mounting seat 32 horizontally connected to the top of the support plate 31. A servo motor mechanism 33 is installed on the top of the mounting seat 32. The servo motor mechanism 33 is composed of a servo motor and a reducer. The output end of the servo motor mechanism 33 is connected to a first vertical plate 34. The servo motor transmits the driving force to the reducer, and the reducer converts the driving force and applies it to the first vertical plate 34. The first vertical plate 34 rotates synchronously. A horizontal plate 35 is provided at the bottom of the first vertical plate 34. Two slides 36 are provided on the top of the horizontal plate 35, one of which is fixedly connected to the horizontal plate 35, and the other slide 36 is slidably connected to the horizontal plate 35. At the top of the horizontal plate 35, the bottom of the first vertical plate 34 is connected to the top of one of the fixedly connected slides 36, and the top of the other slidably connected slide 36 is connected to the fixed plate 37 and the second vertical plate 391. The tops of the fixed plate 37 and the second vertical plate 391 are penetrated and slidably connected with a support rod 38, one end of the support rod 38 is connected to the inner wall of the frame 12, and the base 7 and the leaf disk 8 are arranged between the first vertical plate 34 and the second vertical plate 391. When the first vertical plate 34 rotates, it drives the slide 36, the horizontal plate 35, the fixed plate 37 and the second vertical plate 391 to rotate, and then drives the base 7 to rotate to pour out the residual powder, and then the angles of the base 7 and the leaf disk 8 are adjusted to the angle to be processed.

[0060] See also Figure 4 and Figure 5 Since the base 7 and the blade disk 8 may fall off during rotation, a driving cylinder 39 is horizontally arranged on the side wall of the horizontal plate 35. The piston rod and the cylinder shell of the driving cylinder 39 are respectively connected to the two slides 36. An L-shaped plate 393 is connected to the side wall of the second vertical plate 391. A limiting rod 394 is horizontally connected to the side of the L-shaped plate 393 away from the second vertical plate 391. A placing plate 392 is horizontally connected to the side of the first vertical plate 34 away from the servo motor mechanism 33. The limiting rod 394 is inserted into the inside of the placing plate 392. When the base 7 and the blade disk 8 are placed on the top of the placing plate 392, the driving cylinder 39 is The piston rod of the cylinder 39 contracts, causing the two slides 36 to approach each other. One of the slides 36 that is slidably connected to the cross plate 35 drives the fixed plate 37 and the second vertical plate 391 to slide on the outer wall of the support rod 38. The second vertical plate 391 drives the L-shaped plate 393 and the limit rod 394 to move synchronously. The limit rod 394 gradually slides into the interior of the placement plate 392. During this process, the first vertical plate 34 and the second vertical plate 391 cooperate to clamp and fix the base 7 to prevent the base 7 and the blade disk 8 from falling off during subsequent flipping. After the powder falls, some of the remaining powder and unmelted particles are cleaned manually.

[0061] In the second embodiment, since the blade disk 8 is made by 3D printing and bonded to the base 7 after printing, there will be unmelted particles between adjacent blades inside the blade disk 8, and the unmelted particles in the dead corners cannot be completely cleaned by conventional vacuuming.

[0062] See also Figure 2 To this end, a grabbing assembly 2 is installed on the inner top wall of the frame 12, and a first trimming assembly 5 is installed at the bottom of the grabbing assembly 2. The grabbing assembly 2 is used to drive the first trimming assembly 5 to move, so that the first trimming assembly 5 moves to the top of the blade disk 8 to clean the powder and unmelted particles on the surface of the blade disk 8, and the first trimming assembly 5 can be adjusted according to the shape of the blades in the blade disk 8 to achieve the purpose of thorough cleaning. The specific structure of the grabbing assembly 2 is as follows:

[0063] See also Figure 2 In this embodiment, the grabbing assembly 2 includes two groups of first connecting rods 21 installed on the top wall inside the frame 12, each first connecting rod 21 is slidably connected with an electric transfer block 22, a second connecting rod 23 is connected between the two electric transfer blocks 22, and the outer wall of the second connecting rod 23 is slidably connected with a rotating cylinder 24, and the first trimming assembly 5 is installed at the bottom of the rotating cylinder 24. When the angle adjustment of the base 7 and the blade disk 8 is completed, the electric transfer block 22 slides on the corresponding first connecting rod 21, and the rotating cylinder 24 slides on the outer wall of the second connecting rod 23, thereby adjusting the relative position of the first trimming assembly 5 and the blade disk 8. The first trimming assembly 5 moves to the top of the blade disk 8 and cleans it, and the first trimming assembly 5 can clean multiple blades at a time. After one cleaning, the rotating cylinder 24 drives the first trimming assembly 5 to rotate an angle of a blade gap, and then the first trimming assembly 5 is used for secondary cleaning until all unmelted particles on the blade side walls are completely cleaned.

[0064] See also Figure 7-Figure 11 The specific structure of the first trimming component 5 is as follows:

[0065] The first trimming component 5 includes a lifting cylinder 51 installed at the bottom of the grabbing component 2 and a pneumatic chuck 52 connected to the end of the piston rod of the lifting cylinder 51. The bottom of the pneumatic chuck 52 is equidistantly slidably connected with multiple groups of moving blocks 53. A connecting block 54 is installed at the bottom of each moving block 53. The pneumatic chuck 52 drives the multiple groups of moving blocks 53 to approach or move away from each other synchronously, and the corresponding connecting blocks 54 are displaced synchronously. A supporting plate 55 is horizontally connected to the bottom of the connecting block 54. The bottom of the supporting plate 55 is rotatably connected to two driven gears 56. The two driven gears 56 are meshed with each other. The outer walls of the two driven gears 56 are horizontally provided with connecting platforms 593. A first trimming motor 57 is installed on the top of the connecting platform 593. The output end of the first trimming motor 57 passes through the corresponding connecting platform 593 and is connected to a roller 58. When the connecting block 54 moves, it drives the corresponding supporting plate 55 to move synchronously, and then drives the various components installed on the supporting plate 55 to move synchronously.

[0066] Specifically, after the first trimming assembly 5 moves to directly above the blade disk 8, the pneumatic chuck 52 and the moving block 53 are driven to move downward as a whole through the lifting cylinder 51. During this process, the pneumatic chuck 52 drives the multiple moving blocks 53 to separate at equal distances, and the connecting block 54 installed on the moving block 53 and the various components connected to the bottom of the connecting block 54 move synchronously. The two rollers 58 corresponding to each connecting block 54 extend downward to the gap between the two blades on the blade disk 8, and the first trimming motor 57 drives the corresponding roller 58 to rotate, and the roller 58 cleans the adhered unmelted particles on the side wall of the blade.

[0067] See also Figure 7-Figure 11 A driving motor 59 is installed at the bottom of the carrier plate 55, and the output end of the driving motor 59 is connected to a driving gear 591, which meshes with one of the driven gears 56. A rotating shaft 594 is horizontally connected to one side of each connecting platform 593 close to the corresponding driven gear 56, and one end of the rotating shaft 594 away from the connecting platform 593 is rotatably connected to the outer wall of the corresponding driven gear 56. A torsion spring 595 is provided on the outer wall of the rotating shaft 594, and the two ends of the torsion spring 595 are respectively connected to the side wall of the corresponding connecting platform 593 and the outer wall of the driven gear 56. When the roller 58 cleans the side wall of the blade, the driving motor 59 drives the driving gear 591 to rotate. The gear 591 rotates, and the driving gear 591 drives one of the driven gears 56 to rotate. The two driven gears 56 mesh with each other and rotate, thereby driving the rotating shaft 594 connected to the driven gear 56 and the connecting platform 593 to move in a circular motion. The connecting platform 593 drives the corresponding first trimming motor 57 and the roller 58 to move synchronously. The two corresponding rollers 58 separate from each other and fit with the adjacent side walls of the two blades, so that the rollers 58 clean the unmelted particles on the side walls of the blades while the pneumatic chuck 52 drives the moving block 53 and the connecting block 54 to move, so that the rollers 58 move along the side walls of the blades to clean a large area of ​​the unmelted particles on the side walls of the blades.

[0068] During the movement, the roller 58 is affected by the blade angle and swings, driving the corresponding shaft 594 to rotate, and the corresponding torsion spring 595 twists and rotates. During this process, the roller 58 can adapt to the curved blades to achieve the purpose of adaptive swinging cleaning of the curved blades.

[0069] See also Fig.10 A telescopic rod 598 is installed on the top of the connecting platform 593, and a positioning hole is opened on the outer side wall of the driven gear 56. The size of the positioning hole is compatible with the size of the piston rod end of the telescopic rod 598.

[0070] When the roller 58 is not affected by the blade angle, the torsion force of the torsion spring 595 drives the connecting platform 593 to reset until the roller 58 has cleaned all positions on the inner wall of the blade. Then the telescopic rod 598 is extended, and its piston rod is inserted into the corresponding positioning hole, thereby limiting the angle of the connecting platform 593 to a horizontal position, while the corresponding roller 58 remains in a vertical state.

[0071] When the first trimming component 5 has finished cleaning the particles in the same number of blade gaps, the grabbing component 2 is used to drive the first trimming component 5 to rotate as a whole by an angle of a blade gap, and then the particle cleaning operation is performed again through the above steps, and this process is repeated until all the blade side walls are cleaned.

[0072] See also Fig.11 In this embodiment, a plurality of grooves 596 are formed around and equidistantly around the outer wall of the rotating roller 58 , a scraper block 592 is inserted into each groove 596 , and a spring 597 is connected between the scraper block 592 and the inner wall of the corresponding groove 596 .

[0073] Since there may be dead corners on the inner walls of some blades, unmelted particles may fill the dead corners. Therefore, when the roller 58 cleans the side walls of the blades, the scraper blocks 592 are squeezed to shrink toward the corresponding grooves 596 and squeeze the reeds 597. When the roller 58 moves to the dead corner of the blade, the reaction force of the reeds 597 pushes the corresponding scraper blocks 592 out. The scraper blocks 592 extend toward the dead corner of the blade and are not restricted by the squeezing of the inner walls of the blades. The roller 58 drives multiple scraper blocks 592 to rotate synchronously, thereby achieving the purpose of cleaning the dead corners of the blades.

[0074] Furthermore, the blades are curved, so when the roller 58 cleans the inner wall of the blade, the multiple scraping blocks 592 on the outer wall of the roller 58 will adapt to the different bending angles of the inner wall of the blade, thereby achieving the purpose of adaptive cleaning of the inner wall of the blade.

[0075] In the third embodiment, unmelted particles will also appear at the bonding point between the blade disk 8 and the base 7. Even if the metal powder is discharged, the unmelted particles will still adhere to this position, and the blade disk 8 and the base 7 need to be separated later. After separation, secondary cleaning and repeated transfer are required, which makes the operation cumbersome and fails to achieve the purpose of thorough and quick cleaning.

[0076] See also Figure 2 , Figure 3 and Figure 6 To this end, a second trimming component 6 is installed on the inner bottom wall of the frame 12, the flipping component 3 and the second trimming component 6 are arranged in parallel, and a cutting component 4 is installed on one side of the first vertical plate 34. When the flipping component 3 clamps the base 7, the first trimming component 5 and the grabbing component 2 cooperate to grab and clamp the leaf disk 8, and the cutting component 4 cuts the bonding between the base 7 and the leaf disk 8 to achieve the purpose of separating the base 7 and the leaf disk 8. After that, the first trimming component 5 and the grabbing component 2 cooperate to lift the leaf disk 8 and move it to the position of the second trimming component 6. The bottom of the leaf disk 8 is exposed to the outside and faces the second trimming component 6. The second trimming component 6 cleans the bottom of the leaf disk 8. The staff only needs to place it once to complete the purpose of thoroughly cleaning the leaf disk 8.

[0077] See also Figure 6 The specific structure of the cutting component 4 is as follows:

[0078] In this embodiment, the cutting assembly 4 includes mounting plates 42 symmetrically mounted on both sides of the first vertical plate 34, a guide rod 43 is horizontally connected between the two mounting plates 42, a slider 41 is slidably connected to the outer wall of the guide rod 43, and the bottom of the slider 41 is flush with the top of the base 7. When all the blades of the leaf disk 8 are cleaned, the roller 58 moves to a position where the blades are close to the center of the leaf disk 8, the drive motor 59 stops running, the roller 58 clamps the leaf disk 8, and then the leaf disk 8 is cut by the cutting assembly 4 to separate the base 7 and the leaf disk 8, and the leaf disk 8 is lifted and displaced by the grabbing assembly 2 and the first trimming assembly 5.

[0079] See also Figure 2 and Figure 3 The specific structure of the second trimming component 6 is as follows:

[0080] In this embodiment, the second trimming assembly 6 includes a fixing seat 61 installed on the inner bottom wall of the frame 12, and a processing mechanism 62 is installed on the top of the fixing seat 61. The fixing seat 61 is used to position the processing mechanism 62, and the processing mechanism 62 is used to clean the bottom of the leaf disk 8. The specific structure of the processing mechanism 62 is as follows:

[0081] See also Figure 2 and Figure 3In this embodiment, the processing mechanism 62 includes a second trimming motor 621 installed on the top of the fixing seat 61, and a turntable 622 is horizontally installed on the top of the output end of the second trimming motor 621.

[0082] See also Figure 3 A plurality of circles of trimming columns 623 are equidistantly arranged around the top of the turntable 622 , and the protrusions between each circle of trimming columns 623 are staggered. A scraper bar 624 is installed on the top of the turntable 622 , and the scraper bar 624 extends from the center of the turntable 622 to the edge.

[0083] After the blade disk 8 moves to the top of the turntable 622, the first trimming component 5 cancels the clamping of the blade disk 8, and the blade disk 8 falls to the top of the turntable 622. Then, the first trimming component 5 re-clamps the blade disk 8, that is, the blade disk 8 is clamped at the bottom end of the outer wall of the roller 58, and then the turntable 622 is driven to rotate by the second trimming motor 621, so that the trimming column 623 and the scraper 624 cooperate to clean the unmelted particles at the bottom of the blade disk 8, that is, the trimming column 623 grinds the unmelted particles at the bottom of the blade disk 8 into powder, and the scraper 624 scrapes off the powder or partially unmelted particles adhering to the bottom of the blade disk 8. After the blade disk 8 is cleaned, the grabbing component 2 can move the blade disk 8 out.

[0084] Embodiment 4, the specific working steps of a processing system for 3D printing of an engine blisk are as follows:

[0085] S1. The staff places the base 7 and the blade disk 8 to be processed on the top of the flip assembly 3, and then adjusts the angles of the base 7 and the blade disk 8 to the angle to be processed through the flip assembly 3, and the residual powder is poured out.

[0086] The more specific steps of S1 are:

[0087] S11. The staff places the base 7 and blade disk 8 to be processed on the top of the placement plate 392, and then drives the piston rod of the cylinder 39 to contract, causing the two slides 36 to approach each other. One of the slides 36 that is slidably connected to the horizontal plate 35 drives the fixed plate 37 and the second vertical plate 391 to slide on the outer wall of the support rod 38. The second vertical plate 391 drives the L-shaped plate 393 and the limit rod 394 to move synchronously. The limit rod 394 gradually slides into the interior of the placement plate 392. During this process, the first vertical plate 34 and the second vertical plate 391 cooperate to clamp and fix the base 7.

[0088] S12. Then, the servo motor mechanism 33 drives the first vertical plate 34 to rotate, and the first vertical plate 34 drives the slide 36, the horizontal plate 35, the fixed plate 37 and the second vertical plate 391 to rotate, thereby driving the clamped base 7 to rotate, and the remaining powder is poured out. Then, the angle of the base 7 and the leaf disk 8 is adjusted to the angle to be processed.

[0089] S2. Control the first trimming component 5 to move to the top of the blade disk 8 through the grabbing component 2, and then drive the pneumatic chuck 52 and the moving block 53 to move downward as a whole through the lifting cylinder 51. During this process, the pneumatic chuck 52 drives multiple moving blocks 53 to separate at equal distances, and the connecting block 54 installed on the moving block 53 and the various components connected to the bottom of the connecting block 54 move synchronously. The two rollers 58 corresponding to each connecting block 54 extend downward to the gap between the two blades on the blade disk 8. The first trimming motor 57 drives the corresponding roller 58 to rotate, and the roller 58 cleans the adhered unmelted particles on the side wall of the blade.

[0090] The more specific steps of S2 are:

[0091] S21. When the angle adjustment of the base 7 and the blade disk 8 is completed, the electric transfer block 22 slides on the corresponding first connecting rod 21, and the rotating cylinder 24 slides on the outer wall of the second connecting rod 23, thereby adjusting the relative position of the first trimming component 5 and the blade disk 8. The first trimming component 5 moves to the top of the blade disk 8. When the first trimming component 5 moves to the top of the blade disk 8, the pneumatic chuck 52 and the moving block 53 are driven by the lifting cylinder 51 to move downward as a whole. During this process, the pneumatic chuck 52 drives multiple moving blocks 53 to separate at equal distances, and the connecting block 54 installed on the moving block 53 and the various components connected to the bottom of the connecting block 54 move synchronously. The two rollers 58 corresponding to each connecting block 54 extend downward to the gap between the two blades on the blade disk 8. The first trimming motor 57 drives the corresponding roller 58 to rotate, and the roller 58 cleans the bonded unmelted particles on the side wall of the blade.

[0092] S3. During the cleaning process of the side wall of the blade, the roller 58 drives the driving gear 591 to rotate through the driving motor 59, and the driving gear 591 drives one of the driven gears 56 to rotate. The two driven gears 56 mesh with each other and rotate, thereby driving the rotating shaft 594 connected to the driven gear 56 and the connecting platform 593 to move in a circular manner. The connecting platform 593 drives the corresponding first trimming motor 57 and the roller 58 to move synchronously. The two corresponding rollers 58 separate from each other and fit with the adjacent side walls of the two blades, so that while the roller 58 cleans the unmelted particles on the side wall of the blade, the pneumatic chuck 52 drives the moving block 53 and the connecting block 54 to move, so that the roller 58 moves along the side wall of the blade to clean a large area of ​​the unmelted particles on the side wall of the blade.

[0093] S4. During the movement, the roller 58 is affected by the blade angle and swings, driving the corresponding shaft 594 to rotate. At the same time, the corresponding torsion spring 595 twists and rotates. When the roller 58 is not affected by the blade angle, the torsion force of the torsion spring 595 drives the connecting platform 593 to reset until the roller 58 cleans all positions on the inner wall of the blade. When the first trimming component 5 cleans the same number of particles in the gaps between the blades, the grabbing component 2 is used to drive the first trimming component 5 to rotate as a whole through the angle of a blade gap, and then the particle cleaning operation is performed again through the above steps, and this process is repeated until all the side walls of the blades are cleaned.

[0094] S5. When all blades of the leaf disk 8 are cleaned, the roller 58 moves to a position where the blades are close to the center of the leaf disk 8, the drive motor 59 stops running, the roller 58 clamps the leaf disk 8, and then the leaf disk 8 is cut by the cutting component 4 to separate the base 7 and the leaf disk 8, and the leaf disk 8 is lifted and displaced by the grabbing component 2 and the first trimming component 5.

[0095] The more specific steps of S5 are:

[0096] S51. When all blades of the leaf disk 8 are cleaned, the roller 58 moves to a position where the blades are close to the center of the leaf disk 8, the drive motor 59 stops running, the roller 58 clamps the leaf disk 8, and then moves on the guide rod 43 through the slider 41 to perform laser cutting on the leaf disk 8. After the base 7 and the leaf disk 8 are separated, the leaf disk 8 is lifted and displaced by the cooperation of the grabbing component 2 and the first trimming component 5.

[0097] S6. The leaf disk 8 is moved to the top of the second trimming assembly 6. The bottom of the leaf disk 8 is cleaned by the second trimming assembly 6. After the cleaning is completed, the grabbing assembly 2 can move the leaf disk 8 out.

[0098] The more specific steps of S6 are:

[0099] S61, after the blade disk 8 moves to the top of the turntable 622, the first trimming component 5 cancels the clamping of the blade disk 8, and the blade disk 8 falls to the top of the turntable 622. Then the first trimming component 5 re-clamps the blade disk 8, specifically, the blade disk 8 is clamped at the bottom end of the outer wall of the roller 58, and then the turntable 622 is driven to rotate by the second trimming motor 621, so that the trimming column 623 and the scraper 624 cooperate to clean the unmelted particles at the bottom of the blade disk 8. After the cleaning is completed, the grabbing component 2 can move the blade disk 8 out.
