[0002] Aviation refers to the navigation activities of manned or unmanned aircraft within the Earth's atmosphere, while spaceflight refers to the navigation activities of manned or unmanned spacecraft outside the Earth's atmosphere, also known as spaceflight or cosmic travel. Components required for aviation machinery need to be ground and deburred before use. Ring-shaped components are widely used and are particularly important. Grinding the outer surface of ring-shaped components is essential. Current technology for grinding the outer surface of ring-shaped components generally uses an inner ring limiter, with a grinding machine on the outer side performing fine grinding of the outer surface burrs. However, the aforementioned common deburring devices still have shortcomings:
[0003] Traditional grinding devices typically place ring-shaped components on a table for limiting grinding. The uneven surface of the table can lead to poor grinding accuracy. Furthermore, the lack of protective devices during the grinding process means that grinding debris may be thrown out by the grinder, causing damage to the skin and other parts of the worker. Utility Model Content
[0004] The purpose of this invention is to provide a burr-removing device for aerospace parts, in order to solve the problems mentioned in the background art. Traditional burr-removing devices generally place the ring-shaped parts on a table for limiting and burr removal. The uneven surface of the table leads to poor burr removal accuracy. Furthermore, the lack of protective devices during the burr removal process means that the burrs may be thrown out by the burr remover, causing damage to the skin and other parts of the workers.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a deburring device for aerospace parts, comprising a grinding table and two grinding machines fixedly installed at the top ends of the grinding table. Each of the two grinding machines is equipped with a cleaning brush, and protective slides are provided on both sides of each grinding machine. A protective device for preventing splashing during grinding is slidably connected between adjacent protective slides. A threaded post with a hole is fixedly connected to the center of the top of the grinding table, and a support assembly for assisting in clamping the parts is threadedly connected to the surface of the threaded post with the hole. A speed reducer is fixedly installed inside the grinding table, and a clamping assembly is fixedly connected to the output end of the speed reducer.

The surface of the protective door is slidably connected to the interior of the protective slide. A cleaning brush on the other side cleans the polishing layer, which can prevent the polishing efficiency from decreasing due to metal debris getting stuck in the polishing cylinder. It also provides protection in the direction of the polishing debris being thrown out on both sides, and has an observation port to ensure observation of the polishing process while protecting the workers.
[0007] Preferably, the clamping assembly includes a clamping slot block, a grinding rotating rod fixedly connected to the bottom of the clamping slot block, one end of the grinding rotating rod fixedly connected to the output end of the reducer, clamping support rods slidably connected to the four sides of the clamping slot block, a clamping screw fixedly connected to the top of the clamping slot block, a push block assembly connected to the surface slider of the clamping screw, a handle rotatably connected to the top of the push block assembly, the handle threadedly connected to the clamping screw, a connecting rotating rod provided between the push block assembly and the clamping support rods, a locking nut threadedly connected to one end of the surface of the clamping screw, and a grinding rotating rod rotatably connected to a threaded post with a hole.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] Please see Figure 1-5This utility model provides a burr-removing device for aerospace parts, including a grinding table 1 and grinding machines 2 fixedly installed at both ends of the top of the grinding table 1. Each of the two grinding machines 2 is equipped with a cleaning brush 3. Each of the two grinding machines 2 is equipped with a protective slide 4 on both sides. A protective device for preventing splashing during grinding is slidably connected between two adjacent protective slides 4. A threaded post 10 with a hole is fixedly connected to the middle of the top of the grinding table 1. A support component for assisting in clamping the parts is threadedly connected to the surface of the threaded post 10 with a hole. A reducer is fixedly installed inside the grinding table 1. A clamping component is fixedly connected to the output end of the reducer.
[0021] See Figure 2 Furthermore, the protective device includes two protective doors 5, two connecting rods 6 are fixedly connected between the two protective doors 5, a push-pull handle 7 is fixedly installed in the middle of one side of one of the protective doors 5, an observation port 9 is provided on the surface of one of the protective doors 5, two limiting magnets 8 are provided at one end of one of the protective doors 5, and the surface of the protective door 5 is slidably connected to the inside of the protective slide 4.
[0022] During use, some debris will be flung out during the polishing process, which may come into contact with the exposed skin of the workers. Over time, this may damage the workers' skin health. Therefore, when polishing is required, hold the push-pull handles 7 on both sides and move them towards the middle. At this time, the protective door 5 slides inside the protective slide 4. Since the two protective doors 5 are connected by the connecting rod 6, pulling one protective door 5 can move the other protective door 5. The protective door 5 can directly cover the entire polishing table 1. During the polishing process, the internal situation can be observed through the observation port 9. The protective door 5 is made of metal, but there is a transparent glass at the observation port 9 to observe the polishing process. After the two protective doors 5 are closed, the two limiting magnets 8 at one end of one of the protective doors 5 will attract each other, allowing the protective door 5 to close. The thickness of the limiting magnet 8 is greater than that of the protective slide 4, so it will be stuck at one end of the protective slide 4 to achieve the limiting.
[0023] See Figure 3-5Furthermore, the clamping assembly includes a clamping slot 18, with a grinding rotating rod fixedly connected to the bottom of the clamping slot 18. One end of the grinding rotating rod is fixedly connected to the output end of the reducer. Clamping support rods 20 are slidably connected to all four sides of the clamping slot 18. A clamping screw 19 is fixedly connected to the top of the clamping slot 18. A push block assembly is connected to the surface of the clamping screw 19 via a slider. A handle is rotatably connected to the top of the push block assembly and threadedly connected to the clamping screw 19. A connecting rotating rod 21 is provided between the push block assembly and the clamping support rods 20. A locking nut 27 is threadedly connected to one end of the surface of the clamping screw 19. The grinding rotating rod is rotatably connected to a threaded post 10 with holes. The push block assembly includes a clamping sleeve 22. Multiple screw grooves 23 are provided on the outer side of the clamping screw 19. The surface of the clamping sleeve 22 is slidably connected to the inside of the screw grooves 23. A rotating disk 24 is fixedly connected to one end of the clamping sleeve 22. ， The handle assembly includes a threaded handle 25, one end of which has a rotating groove 26. The rotating groove 26 is rotatably connected to the rotating disk 24. One side of the locking nut 27 is in contact with one side of the threaded handle 25. The support assembly includes a threaded disk 11. The surface of the threaded disk 11 has multiple placement grooves 12. The inner walls of the multiple placement grooves 12 have support grooves 13. The connection between the multiple placement grooves 12 and the threaded disk 11 has a limit groove 14. The interior of the multiple placement grooves 12 is slidably connected to a support member. The support member includes a support slide rod 17. One end of the support slide rod 17 is fixedly connected to a push-pull plate 16. The other end of the support slide rod 17 is fixedly connected to a limit block 15. The surface of the support slide rod 17 is slidably connected to the interior of the placement groove 12.
[0024] During use, when grinding, we often encounter annular parts of different sizes and widths. When machining annular parts with larger diameters, we rotate the threaded disc 11, which is threaded onto the threaded post 10 with holes. The position of the threaded disc 11 is determined according to the thickness of the part being machined. This ensures a stable horizontal position when clamping inside the ring, which is beneficial for machining accuracy. Because the diameter of the part being machined is large, the diameter of the threaded disc 11 may be smaller than the inner diameter of the annular part. In this case, we sequentially pinch the push-pull plate 16 and pull the support slide rod 17 outward. All four support slide rods 17 are pulled out from inside the mounting groove 12 until they can support the machined parts. The mounting groove 12 has a support groove 13 inside, which can make the support of the parts more stable. Limiting blocks 15 are fixedly connected to the support slide rods 17. The limiting blocks 15 slide inside the limiting groove 14 to prevent the support slide rods 17 from falling off during use. After the threaded disc 11 moves to the appropriate position, the annular part is passed through the clamping mechanism and fixed on the plane formed by the four support slide rods 17. At this time, the threaded handle 25 is rotated, and the threaded handle 25 is threadedly connected to the clamping screw 19. Therefore, at this time, the threaded handle 25 moves downward. A screw groove 23 is provided on the surface of the clamping screw 19. The clamping sleeve 22 is slidably connected to the screw groove 23, and a rotating disk 24 is fixedly connected to one end of the clamping sleeve 22. A rotating groove 26 is provided at one end of the threaded handle 25, and the rotating disk 24 is rotatably connected to the rotating groove 26. Therefore, when the threaded handle 25 moves downward, the clamping sleeve 22 moves downward. Rod seats are fixedly connected to all four sides of the clamping sleeve 22, and rod seats are also provided on the surface of the supporting slide rod 17. A connecting rotating rod 21 is rotatably connected between the two rod seats. When the clamping sleeve 22 moves downward, the four clamping support rods 20 press against the inside of the annular component to limit the movement, and the locking nut 27 is rotated to lock the threaded handle 25. At this time, the support slide rod 17 can be retracted into the placement groove 12, and the threaded disc 11 can be reset to prevent it from affecting the processing. When processing smaller parts, the support slide rod 17 can be left unexpanded. At this time, the grinder 2 and the reducer are started. The output end of the reducer is fixedly connected to the grinding rotor. When the reducer is started, it drives the grinding rotor to rotate, which in turn drives the entire clamping assembly to rotate. At this time, the parts will also rotate, and the burrs on the outer surface will be ground.
[0025] In use, this embodiment of the application allows for clamping and grinding of parts according to different applicable diameters during processing. The support assembly enables horizontal clamping of the parts, and the vertical position of the threaded disc 11 can be adjusted according to the required clamping position. This allows for stable clamping of parts of different thicknesses, improving the precision of burr removal. It should be noted that this utility model is a burr removal device for aerospace parts.
