Description

Technical Field

[0001] The present application relates to the technical field of polishing and spraying, and in particular to an integrated device for polishing and spraying a heat pipe of a spacecraft. Background Art

[0002] Spacecraft thermal control aluminum-ammonia heat pipes are mainly made of aluminum, a material that is lightweight, corrosion-resistant and has excellent heat transfer properties. Aluminum has a low density, only about 1 / 3 of steel, which gives aluminum-ammonia heat pipes significant advantages in application scenarios such as spacecraft that require strict weight control. At the same time, aluminum-ammonia heat pipes also have good thermal conductivity and can transfer heat quickly, which is crucial for the thermal control system of spacecraft.

[0003] The manufacturing process of aluminum-ammonia heat pipes for spacecraft thermal control involves multiple steps, including raw material preparation, extrusion molding, heat treatment, machining and shaping, surface treatment, special processing, and quality inspection and testing. Currently, the grinding and spraying processes for aluminum-ammonia heat pipes for spacecraft thermal control have higher technical requirements and special features than other heat pipes. Typically, a single aluminum-ammonia heat pipe is fixed before grinding and spraying. The time between grinding and spraying must be strictly controlled. Spraying should be performed as soon as possible after grinding to avoid secondary oxidation or contamination of the surface. Manual spraying can lead to uneven coating thickness or defects. Therefore, after grinding the heat pipe on the grinder, the heat pipe must be removed and installed on the sprayer for spraying. Once all are completed, the remaining heat pipes are fixed and then polished and sprayed again. This processing method can only process one aluminum-ammonia heat pipe at a time and the heat pipes must be transferred to different processing machines for processing. This method is not only time-consuming and labor-intensive, but also difficult to meet the needs of large-scale production. Summary of the Invention

[0033] As Figure 1 and Figure 2 shown, this embodiment provides an integrated device for grinding and spraying heat pipes of a spacecraft, including: a workbench 10, a material loading component 20, a grinding and spraying component 30, and a fixing component 40.

[0034] A first guide frame 101 and a second guide frame 102 are installed on the top of the workbench 10. The first guide frame 101 and the second guide frame 102 are perpendicular to each other. The second guide frame 102 is symmetrically arranged on both sides of the workbench 10, and the first guide frame 101 is erected on the upper end of the second guide frame 102.

[0035] The material loading component 20 includes a material loading top plate 201 and a material loading bottom plate 202. The material loading bottom plate 202 is erected on the upper end of the second guide frame 102. The material loading bottom plate 202 is parallel to the first guide frame 101. The material loading bottom plate 202 can move along the extending direction of the second guide frame 102, and the material loading bottom plate 202 can move closer to or away from the first guide frame 101. The material loading top plate 201 is rotatably arranged above the material loading bottom plate. A plurality of heat pipes 1 of the spacecraft are sequentially fixed on the material loading top plate 201 through the fixing component 40.

[0036] The grinding and spraying component 30 is used for grinding and spraying the heat pipes of the spacecraft. Spraying operation can be carried out immediately after grinding. The grinding treatment removes surface defects and improves the adhesion of the coating. The spraying treatment forms the required thermal control coating. The grinding and spraying component 30 is arranged on the first guide frame 101 and can be translated on the first guide frame 101 manually or driven by a motor. That is, the grinding and spraying component 30 is translated on the first guide frame 101 to different heat pipes 1 of the spacecraft, and continuously grinds and sprays different heat pipes 1. And the grinding and spraying component 30 can move along the extending direction of the second guide frame 102, and the grinding and spraying component 30 moves closer to or away from the heat pipes 1 of the spacecraft.

[0037] As Figure 3As shown, the fixing member 40 includes a first fixing plate unit 401 and a second fixing plate unit 402. The first fixing plate unit 401 includes a plurality of first fixing plates 4011 arranged in parallel on the loading top plate 201. The second fixing plate unit 402 includes a plurality of second fixing plates 4021 arranged in parallel. The plurality of second fixing plates 4021 arranged in parallel are connected as a whole. A first V-shaped block 4012 is arranged on the first fixing plate 4011, and a second V-shaped block 4022 is arranged on the second fixing plate 4021. The first V-shaped block 4012 and the second V-shaped block 4022 cooperate with each other to fix the spacecraft heat pipe 1 between the first V-shaped block 4012 and the second V-shaped block 4022.

[0038] The staff manually place a plurality of spacecraft heat pipes 1 on the first fixing plate unit 401, and the spacecraft heat pipes 1 correspond to the first fixing plates 4011 one by one. The spacecraft heat pipes 1 are embedded in the first V-shaped blocks 4012. Then, the second fixing plate unit 402 and the first fixing plate unit 401 are overlapped and fixed. The plurality of second fixing plates 4021 in the second fixing plate unit 402 correspond to the plurality of first fixing plates 4011 one by one. The first V-shaped block 4012 and the second V-shaped block 4022 cooperate to fix the spacecraft heat pipe 1 between the first V-shaped block 4012 and the second V-shaped block 4022. After the spacecraft heat pipes 1 are fixed and clamped by multiple pairs of first V-shaped blocks 4012 and second V-shaped blocks 4022, a neat row of spacecraft heat pipes 1 is formed.

[0039] The grinding and spraying assembly 30 moves on the first guide frame 101 until the grinding and spraying assembly 30 corresponds to the spacecraft heat pipe 1 at the edge in the neat row of spacecraft heat pipes 1.

[0040] Coarsely adjust the distance between the spacecraft heat pipe 1 and the grinding and spraying assembly 30. The loading bottom plate 202 in the loading assembly 20 approaches the first guide frame 101, that is, the spacecraft heat pipe 1 fixed on the loading top plate 201 approaches the grinding and spraying assembly 30.

[0041] Then finely adjust the distance between the spacecraft heat pipe 1 and the grinding and spraying assembly 30. The grinding and spraying assembly 30 can move along the extension direction of the second guide frame 102, and the grinding and spraying assembly 30 approaches the spacecraft heat pipe 1 again until a part of the grinding and spraying assembly 30 contacts the spacecraft heat pipe 1.

[0042] The grinding and spraying assembly 30 starts to grind the spacecraft heat pipe 1 and then sprays after the grinding is completed.

[0043] After the grinding and spraying of the spacecraft heat pipe 1 are completed, the grinding and spraying assembly moves along the extension direction of the second guide frame 102 and moves away from the spacecraft heat pipe 1. The grinding and spraying assembly 30 moves to the next spacecraft heat pipe 1 until it is aligned with the next spacecraft heat pipe 1, and then the grinding and spraying operations are performed on this spacecraft heat pipe 1.

[0044] Repeat the above operations of moving the grinding and spraying assembly 30 to the next spacecraft heat pipe 1 and performing the grinding and spraying operations until all the spacecraft heat pipes 1 in the whole row facing the grinding and spraying assembly 30 are ground and sprayed.

[0045] The loading base plate 202 in the loading assembly 20 moves away from the first guide frame 101, that is, the spacecraft heat pipe 1 fixed on the loading base plate 201 moves away from the grinding and spraying assembly 30.

[0046] The loading top plate 201 rotates 180° relative to the loading base plate 202, so that the spacecraft heat pipe 1 on the other side that has not been ground and sprayed faces the grinding and spraying assembly 30.

[0047] After the rotation is completed, the grinding and spraying assembly 30 moves on the first guide frame 101 until the grinding and spraying assembly 30 corresponds to the spacecraft heat pipe 1 at the edge in the whole row of spacecraft heat pipes 1.

[0048] Coarsely adjust the distance between the spacecraft heat pipe 1 and the grinding and spraying assembly 30. The loading base plate 202 in the loading assembly 20 moves closer to the first guide frame 101, that is, the spacecraft heat pipe 1 fixed on the loading base plate 201 moves closer to the grinding and spraying assembly 30.

[0049] Then finely adjust the distance between the spacecraft heat pipe 1 and the grinding and spraying assembly 30. The grinding and spraying assembly 30 can move along the extension direction of the second guide frame 102 and moves closer to the spacecraft heat pipe 1 until a part of the grinding and spraying assembly 30 contacts the spacecraft heat pipe 1.

[0050] The grinding and spraying assembly 30 starts to grind the spacecraft heat pipe 1 and performs spraying after the grinding is completed.

[0051] After the grinding and spraying of this spacecraft heat pipe 1 are completed, the grinding and spraying assembly moves along the extension direction of the second guide frame 102 and moves away from the spacecraft heat pipe 1. The grinding and spraying assembly 30 moves to the next spacecraft heat pipe 1 until it is aligned with the next spacecraft heat pipe 1, and then the grinding and spraying operations are performed on this spacecraft heat pipe 1.

[0052] Repeat the above operations of moving the grinding and spraying assembly 30 to the next spacecraft heat pipe 1 and performing the grinding and spraying operations until all the spacecraft heat pipes 1 in the whole row facing the grinding and spraying assembly 30 are ground and sprayed.

[0053] At this time, both side portions of multiple spacecraft heat pipes 1 are polished and sprayed. The second fixing plate unit 402 is removed from the first fixing plate unit 401, and the spacecraft heat pipe 1 is released. Multiple spacecraft heat pipes are removed in sequence, and multiple processed spacecraft heat pipes are obtained at one time.

[0054] In this embodiment, multiple spacecraft heat pipes 1 are fixed on the loading top plate 201 at one time through fixing members, and the operation is simple. After the fixing is completed, the grinding and spraying assembly 30 is moved in the extending direction of the first guide frame 101 so that the grinding and spraying assembly 30 is aligned with the outermost spacecraft heat pipe 1. Then, the loading assembly 20 and the grinding and spraying assembly 30 are moved in sequence along the extending direction of the second guide frame 102 so that the grinding and spraying assembly 30 approaches the spacecraft heat pipe 1. The grinding and spraying assembly 30 grinds and sprays the spacecraft heat pipe 1. Then, the grinding and spraying assembly 30 is moved along the extending direction of the second guide frame 102 so that the grinding and spraying assembly 30 moves away from the spacecraft heat pipe 1. The grinding and spraying assembly 30 is moved in the extending direction of the first guide frame 101 so that the grinding and spraying assembly 30 is aligned with the next spacecraft heat pipe 1 to be processed. The above steps are repeated to grind and spray one side portion of the spacecraft heat pipe 1 in sequence, and multiple spacecraft heat pipes 1 are processed simultaneously, saving time and labor and meeting the requirements of large-scale production.

[0055] The grinding and spraying assembly 30 realizes integrated grinding and spraying processing, reduces the conversion time of the spacecraft heat pipe 1 between the grinding equipment and the spraying equipment, improves the production efficiency, and avoids secondary oxidation or contamination of the polished surface.

[0056] After the processing of one side portion of the spacecraft heat pipe 1 is completed, the loading top plate 201 is rotated so that the other side portion of the spacecraft heat pipe 1 faces the grinding and spraying assembly 30 to realize the grinding and spraying processing of the other side portion, without removing the spacecraft heat pipe 1 for re-fixing, significantly improving the production efficiency and meeting the high-efficiency requirements of large-scale production.

[0057] Such as Figure 3 and Figure 4As shown, in one embodiment, the integrated device for grinding and spraying heat pipes further includes a pressing member 50. The pressing member 50 is used to press the second fixed plate unit 402 onto the first fixed plate unit 401. The pressing member 50 includes a top frame 501, a lifting plate 502, a second screw 503, a knob 504, a limiting rod 505, and a top block 506. The top frame 501 straddles above the fixing member 40, and the two bottom ends of the top frame 501 are respectively fixedly connected to the top surface of the loading top plate 201. The second screw 503 is penetrated through the middle of the top of the top frame 501. The second screw 503 can rotate in the through hole of the top frame 501. The bottom end of the second screw 503 is rotatably connected to the top end of the lifting plate 502. Rotating the second screw 503 can control the lifting of the lifting plate 502. The lifting plate 502 moves up and down in the vertical direction to press or release the second fixed plate unit 402, thereby realizing the pressing or releasing of the spacecraft heat pipe 1. The knob 504 is fixedly connected to the top end of the second screw 503. Rotating the knob 504 can control the rotation of the second screw 503. The limiting rod 505 is penetrated through both sides of the top of the top frame 501. The top block 506 is fixedly arranged at the top end of the limiting rod 505. The top block 506 and the limiting rod 505 cooperate to limit the lifting plate 502 to prevent the spacecraft heat pipe 1 from shifting during the grinding and spraying process.

[0058] As Figure 3 shown, in one embodiment, the second fixed plate unit 402 is fixed to the bottom of the lifting plate 502, and the second fixed plate unit 402 and the lifting plate 502 move together in the vertical direction. After all the spacecraft heat pipes 1 are placed, rotate the knob 504 to drive the second screw 503 to rotate. The lifting plate 502 rotatably connected to the second screw 503 drives the second fixed plate unit 402 to descend together. The second fixed plate unit 402 is fixedly matched with the first unit fixed plate unit 401, and at this time, the lifting plate 502 presses the second fixed plate unit 402, and the fixing and pressing operations of the fixing member 40 are completed synchronously.

[0059] As Figure 5 shown, in one embodiment, side holes 4013 are opened on both side walls of the first V-shaped block 4012. The side holes 4013 are used to enable the first V-shaped block 4012 and the second V-shaped block 4022 to overlap after being combined. The second V-shaped block 4022 can be embedded into the side holes 4013 of the first V-shaped block 4012. When the size of the spacecraft heat pipe 1 is smaller than the space between the first V-shaped block 4012 and the second V-shaped block 4022, the volume of the second V-shaped block 4022 embedded into the side holes 4013 is large, and the spacecraft heat pipe 1 is firmly clamped between the first V-shaped block 4012 and the second V-shaped block 4022. The design of the side holes 4013 enables the first V-shaped block 4012 and the second V-shaped block 4022 to adapt to spacecraft heat pipes 1 with different diameters.

[0060] As Figure 6 andFigure 7 As shown, in one embodiment, the grinding and spraying assembly 30 includes an equipment rack 301, a grinding unit 302, a spraying unit 303, a pushing member 304, a translation member 305, and a first guiding block 306. The equipment rack 301 is used to support and install components such as the grinding unit 302 and the spraying unit 303. The grinding unit 302 is installed at the top of the equipment rack 301. The grinding unit 302 is used to grind the spacecraft heat pipe 1, remove surface defects, and improve the coating adhesion. The spraying unit 303 is installed on one side wall of the equipment rack 301. The spraying unit 303 is used to spray the spacecraft heat pipe 1 that has undergone the grinding operation to form the required thermal control coating. The bottom end of the first guiding block 306 is slidably connected to the first guiding frame 101. When the first guiding block 306 translates on the first guiding frame 101, the equipment rack 301 and the grinding unit 302 and the spraying unit 303 provided on the equipment rack 301 all translate on the first guiding frame 101 in the extending direction of the first guiding frame 101 together with the equipment rack 301. The grinding and spraying assembly 30 can be translated to the corresponding position of the spacecraft heat pipe 1 to be processed as required. The bottom of the equipment rack 301 is slidably connected to the top of the first guiding block 306 along the extending direction of the second guiding frame 102. The equipment rack 301 drives the grinding unit 302 and the spraying unit 303 to approach or move away from the spacecraft heat pipe 1 on the first guiding block 306. The pushing member 304 is used to drive the equipment rack 301 to move along the extending direction of the second guiding frame 102. The translation member 305 is used to drive the equipment rack 301 to move along the extending direction of the first guiding frame 101.

[0061] As Figure 6 shown, in one embodiment, the translation member 305 is provided at the bottom of the equipment rack 301. Specifically, the translation member 305 is provided on the first guiding frame 101. The first guiding frame 101 is composed of two side plates and two slats. The translation member 305 includes a first driving portion 3051 and a first screw 3052. The first driving portion 3051 is installed on one side wall of the first guiding frame 101. The first driving portion 3051 can be a motor. The output shaft of the first driving portion 3051 passes through the side wall surface of the first guiding frame 101 through a bearing movably, and the output portion of the first driving portion 3051 is rotationally connected to one end of the first screw 3052. The first guiding block 306 is slidably connected to the slats. The first driving portion 3051 drives the first screw 3052 to rotate, and the first screw 3052 drives the grinding and spraying assembly 30 to move on the first guiding frame 101, realizing the stable translation of the equipment rack 301 and the grinding unit 302 and the spraying unit 302 installed thereon in the extending direction of the first guiding frame 101, facilitating the processing of spacecraft heat pipes 1 at different positions, and improving the processing efficiency.

[0062] As Figure 6 and Figure 7As shown, in one embodiment, the pusher 304 is disposed at the bottom of the equipment rack 301. The pusher 304 includes a mounting plate 3041, a second driving part 3042, and a fixing frame 3043. The mounting plate 3041 is fixed to one side of the top of the first guiding block 306 for mounting the second driving part 3042. The second driving part 3042 is mounted on one side wall of the mounting plate 3041. The second driving part 3042 can be a cylinder. The fixing frame 3043 is in transmission connection with the output end of the second driving part 3042 and is fixedly connected to the equipment rack 301. The second driving part 3042 drives the fixing frame 3043 to move, and the fixing frame 3043 drives the equipment rack 301 to move together. The equipment rack 301, the grinding unit 302, and the spraying unit 303 move together along the extension direction of the second guiding frame 102 on the first guiding block 306. The second driving part 3042 directly acts on the equipment rack 301 to move, realizing precise movement control of the equipment rack, thereby controlling the grinding unit 302 and the spraying unit 303 to approach or move away from the spacecraft heat pipe, improving the flexibility and automation of the operation.

[0063] As Figure 6 and Figure 7 shown, in one embodiment, the number of the first guiding blocks 306 is multiple. The multiple first guiding blocks 306 correspond to the feet of the equipment rack 301 one by one. A connecting plate 3061 is arranged between the tops of the multiple first guiding blocks 306. The top of the connecting plate 3061 is fixedly connected to the feet at the bottom of the equipment rack 301. The bottom of the connecting plate 3061 is slidably connected to the tops of the first guiding blocks 306 along the extension direction of the second guiding frame 102. The connecting plate 3061 drives the equipment rack 301 to move together, avoiding inconsistent actions of the feet of the equipment rack 301, resulting in tilting and oscillation of the equipment rack 301, providing stable guiding and support for the equipment rack 301, ensuring that the grinding unit 302 and the spraying unit 303 can move smoothly both in the extension direction of the second guiding frame 102 and in the extension direction of the first guiding frame 101, and improving the processing accuracy.

[0064] As Figure 2 and Figure 8 shown, in one embodiment, the loading assembly 20 further includes a moving part 203 and a rotating part 204. The moving part 203 is used to drive the loading assembly 20 to move along the extension direction of the second guiding frame 102. The moving part 203 drives the loading assembly 20 to approach or move away from the grinding and spraying assembly 30. The rotating part 204 is used to drive the loading top plate 201 to rotate relative to the loading bottom plate 202, so that the spacecraft heat pipe 1 fixed on the loading top plate 201 faces the grinding and spraying assembly 30 on the other side. It is not necessary to manually remove the spacecraft heat pipe 1 and then fix it again.

[0065] As Figure 2 and Figure 8As shown, in one embodiment, the moving member 203 includes a third guiding block 2031 and a third driving part. The top of the third guiding block 2031 is fixedly connected to the bottom of the material loading bottom plate 202. The bottom of the third guiding block 2031 is slidably connected to the second guiding frame 102. The movement of the third guiding block 2031 drives the material loading bottom plate 202 to move together on the second guiding frame 102, approaching or moving away from the grinding and spraying assembly 30. The third driving part drives the third guiding block 2031 to move. There is a certain frictional force between the contact surfaces of the third guiding block 2031 and the second guiding frame 102. When the third guiding block 2031 is driven to any position, without applying additional external force to it, it will not move arbitrarily. The cooperative design of the moving member 203 and the second guiding frame 102 provides stable guiding for the material loading bottom plate 202, the material loading top plate 201 thereon, and the fixed spacecraft heat pipe 1, ensuring that the material loading assembly 2 can maintain stability during rotation or movement, and avoiding processing errors caused by shaking.

[0066] As Figure 8 shown, in one embodiment, the rotating member 204 includes a support frame 2041 and a fourth driving part 2042. The support frame 2041 is fixed to the bottom surface of the material loading bottom plate 202 and is used to support the fourth driving part 2042, which is also arranged on the bottom surface of the material loading bottom plate 202 to prevent the fourth driving part 2042 from falling. The fourth driving part 2042 is arranged inside the inner wall of the support frame 2041. The output shaft of the fourth driving part 2042 penetrates through the material loading bottom plate 202 and is in transmission connection with the material loading top plate 201. The fourth driving part 2042 drives the material loading top plate 201 to rotate relative to the material loading bottom plate 202, realizing the rotation control of the spacecraft heat pipe 1 fixed on the material loading top plate 201, facilitating uniform grinding and spraying of each side of the spacecraft heat pipe 1, and improving the processing quality and consistency.
