Description

Technical Field

[0001] This invention relates to the field of additive manufacturing part cleaning structure technology, and more specifically, to an additive manufacturing part powder cleaning device. Background Technology

[0002] In modern commercial aero-engines, the application of additive manufacturing technology has greatly expanded the boundaries of manufacturing and forming, making it unrestricted by any geometric shape. For example, with the maturation of additive manufacturing technology, the additive manufacturing of fuel nozzle rod cores has made mass production possible for this part.

[0003] The fuel nozzle core, with its highly complex internal structure and surrounding flow channels, is a typical integrated complex structural component. Additive manufacturing, based on the discrete-stacking principle and using a digital model as a foundation, employs digital slicing technology to convert the three-dimensional model into a two-dimensional cross-section. This is achieved by laying layers of 15-45 micrometer high-temperature alloy or metal powder particles, followed by selective laser melting and layering of the powder particles to form the final shape. Cleaning the powder remaining inside the fuel nozzle core after forming is a crucial aspect of the additive manufacturing process.

[0004] In the past, after the additive manufacturing of fuel nozzle rod cores, the removal of residual powder was typically done in an open manner. The workpiece was manually held and flipped to allow the powder to flow out through the process outlet. Finally, the workpiece was placed in a plastic bag, and compressed air was used to blow away the internal channels and mesh supports to remove the powder. This process is prone to workpiece impact and deformation, and is highly dependent on manual operation. The poor visibility during blowing from the plastic bag makes it difficult to apply a reasonable and stable powder removal angle to the workpiece, easily leading to incomplete removal of residual powder from the mesh supports and internal channels. During hot isostatic pressing, the powder can fuse with the inner wall of the internal channels, affecting the surface quality of the channels and, in severe cases, clogging them, increasing the difficulty of subsequent removal of the mesh supports. This results in low powder removal efficiency and high labor intensity for the operator. Summary of the Invention

[0005] The purpose of this invention is to provide a powder cleaning device for additive manufacturing parts, which can improve the technical problems of high dependence on manual labor, unstable powder cleaning quality, and low cleaning efficiency in the prior art when cleaning powder in additive manufacturing parts.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0033] At the same time, it should be noted that the terms "first" and "second" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0034] In the description of this invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components, etc. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] The following is an explanation of the terms that may appear in the description of this invention:

[0036] Additive manufacturing: a technology that uses a method of gradually adding materials to create solid parts, also known as 3D printing. Generally, in additive manufacturing, the additively manufactured part is formed on a substrate, and then removed from the substrate after forming.

[0037] Figure 1 This diagram shows the overall structure of the additive manufacturing powder cleaning device 10 provided in this embodiment. Figure 2 This diagram shows the internal structure of the additive manufacturing powder cleaning device 10 provided in this embodiment. Figure 3 This diagram shows a partial structural schematic of the cleaning body 300 in the additive manufacturing powder cleaning device 10 provided in this embodiment. Please refer to the attached diagram. Figures 1-3 This embodiment provides an additive manufacturing part powder cleaning device 10, hereinafter referred to as powder cleaning device 10. The powder cleaning device 10 can clean the powder remaining inside the additive manufacturing part 21. As the name suggests, the additive manufacturing part 21 is a component made by additive manufacturing process.

[0038] The powder cleaning device 10 includes a cleaning body 300. The cleaning body 300 includes a support 310, a rotating structure 320, a substrate support frame 330, and a pneumatic hammer 340. The rotating structure 320 is rotatably mounted on the support 310, and its rotation axis relative to the support 310 is a first axis. The substrate support frame 330 is used to clamp a substrate 20 with an additively manufactured part 21 to be cleaned. The substrate support frame 330 is mounted on the rotating structure 320 and rotates around a second axis under the drive of the rotating structure 320. The second axis is set at an angle to the first axis. Simultaneously, when the rotating structure 320 rotates around the first axis, the substrate support frame 330 rotates synchronously around the first axis. Thus, the superposition of rotations in different directions guides the powder in the additively manufactured part 21 to flow out at a reasonable angle. The pneumatic hammer 340 is mounted on the substrate support frame 330 and is used to vibrate the substrate 20, thereby helping to increase powder flowability, further promoting powder outflow, and improving the powder cleaning quality and efficiency. The powder cleaning device 10 employs multi-angle rotation and high-frequency vibration to rapidly remove powder retained in the additively manufactured part 21, providing excellent cleaning results, particularly for additively manufactured parts 21 with complex internal structures (such as fuel nozzle rods in aircraft engines). Understandably, the powder cleaning device 10 can also be used to clean other types of additively manufactured parts 21.

[0039] The powder cleaning device 10 provided in this embodiment will be further described below:

[0040] Please continue to refer to the reference. Figures 1-3 In this embodiment, the powder cleaning device 10 also includes a chamber 200, and the cleaning body 300 is disposed inside the chamber 200, thereby confining the cleaned powder inside the chamber 200 to prevent the powder from overflowing, thus avoiding the powder from harming the operator's health, avoiding powder waste, and helping to reduce processing costs.

[0041] Specifically, the powder cleaning device 10 also includes a base 100, a chamber 200 mounted on the base 100 to form a closed cleaning space, and a bracket 310 of the cleaning body 300 fixedly mounted on the base 100 to support the cleaning body 300. At the same time, the cleaning body 300 is located in the cleaning space to prevent the cleaned dust from overflowing into the cleaning space.

[0042] Furthermore, the chamber 200 also has a door 211 for allowing the substrate 20 with the additive manufacturing part 21 to be cleaned to enter and exit the chamber 200. Furthermore, the chamber 200 also includes an observation window 216, which is located on the upper side of the cleaning body 300 and is inclined.

[0043] Specifically, the chamber 200 has a top wall 212, and a first side wall 213 and a second side wall 214 disposed opposite each other on both sides of the top wall 212. The first side wall 213 and the second side wall 214 are vertically disposed, while the top wall 212 is horizontally disposed. A door 211 is disposed on the first side wall 213, and the height of the door 211 is higher than the height of the cleaning body 300, so that the substrate 20 with the additive manufacturing part 21 to be cleaned can enter the chamber 200 and be installed on the substrate support frame 330. The chamber 200 also has an inclined wall 215 located between the top wall 212 and the second side wall 214. The inclined wall 215 is inclined relative to the top wall 212 and the second side wall 214, and an observation window 216 is disposed on the inclined wall 215 to facilitate observation of the cleaning status of powder in the cleaning space. Accordingly, the observation window 216 is set at an angle relative to both the second side wall 214 and the top wall 212, and the upper end of the observation window 216 is closer to the first side wall 213 than the lower end. Optionally, the entire cabin 200 is made of sheet metal, and the observation window 216 is made of glass.

[0044] In this embodiment, the powder cleaning device 10 further includes a compressed air gun (not shown), which is used to blow away the additively manufactured part 21 to be cleaned. Specifically, in this embodiment, the compressed air gun is used by an operator to blow away the additively manufactured part 21 by hand. Therefore, two inlets and outlets 217 are provided on the chamber 200, which allow the operator to reach into the cleaning space and use the compressed air gun to blow away the additively manufactured part 21. At the same time, a compressed air inlet 218 is also provided on the first side wall 213 for compressed air to enter. The compressed air inlet 218 is located above the inlets and outlets 217. It is understood that in some other embodiments, the compressed air gun can also be placed in the cleaning space and the compressed air gun can be automatically operated by a robotic arm or other means to blow away the powder.

[0045] In this embodiment, the bracket 310 is disposed in the cleaning space and is fixedly connected to the base 100, thereby supporting the bracket 310 through the base 100. The rotating structure 320 includes a rotating housing 321, a driving bevel gear 322, a driven bevel gear 323, and a fixed bevel gear 324. The rotating housing 321 has a rotating chamber 325, in which the driving bevel gear 322, driven bevel gear 323, and fixed bevel gear 324 are all installed and supported by the rotating housing 321. The driven bevel gear 323 meshes with the driving bevel gear 322, and the fixed bevel gear 324 meshes with the driven bevel gear 323. The gear shaft of the driving bevel gear 322 is rotatably connected to the bracket 310, and the gear shaft of the fixed bevel gear 324 is fixedly connected to the bracket 310. Thus, when the driving bevel gear 322 rotates, the driven bevel gear 323 rotates under the drive of the driving bevel gear 322. The rotation axis of the driving bevel gear 322 is the first axis; in other words, the first axis can also be considered to be collinear with the rotation axis of the driving bevel gear 322. The driven bevel gear 323 is connected to the substrate support frame 330 so that the substrate support frame 330 rotates when the driven bevel gear 323 rotates. The rotation axis of the driven bevel gear 323 is the second axis; in other words, the second axis can also be considered to be collinear with the rotation axis of the driven bevel gear 323.

[0046] Specifically, the driving bevel gear 322, the driven bevel gear 323, and the fixed bevel gear 324 are all rotatably mounted on the rotating housing 321 via bearings. The gear shaft of the driving bevel gear 322 extends out of the rotating housing 321 and is rotatably connected to the bracket 310. The fixed bevel gear 324 is coaxially distributed with the driving bevel gear 322, and its gear shaft extends out of the rotating housing 321 and is fixedly connected to the bracket 310. Thus, during the operation of the rotating structure 320, the fixed bevel gear 324 remains fixed relative to the bracket 310. The driven bevel gear 323 meshes with both the driving bevel gear 322 and the fixed bevel gear 324, and the axis of the driven bevel gear 323 is perpendicular to both the driving bevel gear 322 and the fixed bevel gear 324. That is, in this embodiment, the first axis and the second axis are perpendicular to each other. When the driving bevel gear 322 rotates, it drives the driven bevel gear 323 to rotate. Since the fixed bevel gear 324 remains fixed, the driven bevel gear 323, in addition to rotating around its own axis, also rotates around the fixed bevel gear 324, thereby driving the rotating housing 321 to rotate around the fixed bevel gear 324, that is, to rotate around the first axis relative to the support 310. In this embodiment, the direction of the first axis is as follows: Figure 3 The X direction shown is such that the direction of the second axis is as follows: Figure 3 The Z direction is shown.

[0047] Furthermore, the powder cleaning device 10 also includes a drive motor 400, which is disposed on one side of the drive bevel gear 322 along the first axis and is drively connected to the drive bevel gear 322 to drive the drive bevel gear 322 to rotate around the first axis. Specifically, the powder cleaning device 10 also includes a support frame 410, on which the drive motor 400 is mounted to support the drive motor 400. The drive motor 400 is disposed outside the chamber 200.

[0048] In this embodiment, the substrate support frame 330 includes a frame body 331 and a substrate support 338 mounted on the frame body 331. The frame body 331 includes a square frame portion 332 and a shaft portion 337, with the shaft portion 337 fixedly connected to the outer wall of the square frame portion 332. The shaft portion 337 is connected to the rotary structure 320, and the axis of the shaft portion 337 is a second axis. The substrate 20 is supported and mounted on the side of the square frame portion 332 opposite to the shaft portion 337. A pneumatic hammer 340 is located inside the square frame portion 332 and is mounted on the substrate support 338 to drive the substrate support 338 to vibrate, thereby causing the substrate 20 mounted on the substrate support 338 and the additive manufacturing part 21 on the substrate 20 to vibrate, thereby promoting the outflow of powder inside the additive manufacturing part 21 and increasing the powder cleaning efficiency and effect.

[0049] Specifically, the frame portion 332 is a circumferentially closed square frame component, which includes a first frame edge 333, a second frame edge 334, a third frame edge 335, and a fourth frame edge 336 connected end to end, forming a square space. The shaft portion 337 is fixed to the first frame edge 333 and is located outside the first frame edge 333, that is, on the side of the first frame edge 333 away from the third frame edge 335. The substrate support 338 is mounted on the third frame edge 335 and is located outside the third frame edge 335, that is, on the side of the third frame edge 335 away from the first frame edge 333. The pneumatic cone is mounted on the base plate support 338, and the pneumatic hammer 340 is located inside the square portion 332, that is, the pneumatic hammer 340 is located on the side of the third frame edge 335 close to the first frame edge 333. During the operation of the pneumatic hammer 340, the pneumatic hammer 340 does not contact the square portion 332 to avoid vibration being transmitted to the square portion 332.

[0050] Optionally, the shaft portion 337 and the square portion 332 are integral structures. The shaft portion 337 extends into the rotating housing 321 and is fixedly connected to the gear shaft of the driven bevel gear 323, and is rotatably engaged with the rotating housing 321 through a bearing.

[0051] Furthermore, the substrate support frame 330 also includes a vibration damping member 339 disposed between the substrate support 338 and the frame portion 332. The vibration damping member 339 is used to block the transmission of vibrations from the substrate support 338 to the frame portion 332. Specifically, the substrate support 338 is flexibly connected to the third frame edge 335 of the frame portion 332 via the vibration damping member 339. Optionally, the vibration damping member 339 is a rubber damping member. It is understood that in some other embodiments, other components that can block vibrations can also be used as the vibration damping member 339, such as a vibration damping spring. Furthermore, the substrate support 338 is also provided with locking bolts, and the substrate 20 can be fixedly connected to the substrate support 338 via the locking bolts.

[0052] In this embodiment, the powder cleaning device 10 further includes a conical collecting cylinder 350, which is disposed inside the chamber 200 and located below the substrate support frame 330 to collect powder cleaned from the additive manufacturing part 21. Specifically, in this embodiment, the conical collecting cylinder 350 is an inverted conical structure with a large opening at the upper end. It is mounted on the bracket 310 and located below the substrate support frame 330. It should be noted that, since the substrate support frame 330 is mounted on the rotating structure 320 and rotates under the drive of the rotating structure 320, the conical collecting cylinder 350 should be positioned to avoid the rotational position of the substrate support frame 330, that is, the conical collecting cylinder 350 should be located below the space occupied by the rotation of the substrate support frame 330.

[0053] The powder cleaning device 10 provided in the embodiments of the present invention is used by first observing the position of the rotating structure 320 through the observation window 216 until the rotating structure 320 rotates the substrate support frame 330 to a horizontal state. Then, the door 211 is opened, and the substrate 20 with the additive manufacturing part 21 is moved to the substrate support frame 330 and fixed to the substrate support 338 by multiple locking bolts. The drive motor 400 is controlled to drive the drive bevel gear 322 to rotate at a speed of 1 r / min, and the pneumatic hammer 340 vibrates simultaneously, so that the powder flows out quickly at a reasonable angle. After 20 minutes, the operator observes the inside of the cleaning space through the observation window 216, and reaches into the cleaning space with both hands through the inlet and outlet 217, holding the introduced compressed air gun to blow away the powder process flow hole and internal flow channel of the additive manufacturing part 21. After observing the powder cleaning status through the observation window 216 and confirming that no powder has fallen, the rotating structure 320 is rotated to a horizontal state to complete the powder cleaning operation of the additive manufacturing part 21.

[0054] The powder cleaning device 10 uses a set of motors to control the operation of interlocking bevel gears, forming a linkage platform that drives the additively manufactured part 21 to rotate in multiple directions. This, coupled with high-frequency vibration, achieves rapid powder cleaning, significantly improving powder efficiency and effectively ensuring the quality and stability of powder cleaning. It greatly reduces the operator's workload, is more environmentally friendly by preventing operator exposure to dust, effectively recycles and reuses powder, avoids powder pollution, and reduces manufacturing costs.

[0055] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
