[0002] An aircraft tail is a device installed at the rear of an aircraft, which can enhance flight stability. Most tails include a horizontal tail and a vertical tail, and a few use a V-shaped tail.

[0013] The present invention also discloses a spraying method for an aircraft tail wing, which uses the above-mentioned spraying machine device for an aircraft tail wing, and comprises the following steps:

[0014] S1. First, the aircraft tail to be sprayed is fixed on the placement plate by a conveying device, and then the linear module and the electric telescopic rod are started to drive the rectangular plate at the bottom of the U-shaped frame to move inside the spraying chamber, and then the paint is sent from the pipe inside the slider to the nozzle through the spraying equipment, and the two nozzles are used to spray both sides of the aircraft tail. When the spraying of both sides is completed, the nozzle is moved to the top of the aircraft tail with the cooperation of the linear module and the electric telescopic rod, and then the rotating motor located at the top of the aircraft tail is started to drive the movable plate to rotate ninety degrees on the fixed plate. The second motor is started while the movable plate is rotating, and the output end of the second motor drives the first screw to rotate, and the first screw drives the slider and the nozzle to move inside the movable plate, thereby increasing the distance between the nozzle and the top of the aircraft tail wing. In this way, when the nozzle is spraying the top of the aircraft tail wing, the paint sprayed by the nozzle and the top of the aircraft tail wing will not generate a large impact force to cause a large amount of paint to splash to other parts of the aircraft tail wing, thereby avoiding uneven paint in other parts, thereby improving the spraying effect;

[0015] S2. While the slider drives the spray head to move inward toward the movable plate, the U-shaped rack is synchronously driven to move through the connecting block, thereby driving the large gear to rotate, and further driving the small gear to drive the straight gear to rotate toward the side of the aircraft tail through the first shaft. When the slider stops moving, the two baffles rotate in an inclined state on both sides of the aircraft tail, thereby blocking the paint splashed by the impact of the paint ejected from the spray head on the top of the aircraft tail, so as to avoid the uneven paint caused by the splashed paint flying to other parts of the aircraft tail, thereby further improving the uniformity of the aircraft tail spraying;

[0016] S3. When the spray head sprays the side of the aircraft tail in a horizontal state, the two baffles initially deployed at an angle of thirty degrees can also play the role of blocking the splashed paint generated by the impact of the paint ejected from the spray head on the aircraft tail;

[0017] S4. When the first shaft rotates, the spherical rod rotates from the lowest point to the highest point along the arc-shaped track at the end of the fitting block. Thus, under the action of the arc-shaped track, the spherical rod is pushed to drive the second shaft to move toward the first shaft, and then the straight rack is driven to move toward the straight gear through the connecting rod, thereby driving the second lead screw to rotate. The second lead screw rotates to drive the power block to drive the roller to move toward the folding plate, thereby pushing the folding plate to rotate inward toward the baffle. When the baffle stops rotating, the roller is close to the side of the aircraft tail, thereby reducing the gap between the baffle and the aircraft tail, so as to better block the splashed paint.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Through the provided adjustment mechanism, with the cooperation of the linear module and the electric telescopic rod, the spray head is moved to the top of the aircraft tail. Subsequently, the rotation motor located at the top of the aircraft tail is started to drive the movable plate to rotate 90 degrees on the fixed plate, so that the spray head rotates toward the top of the aircraft tail. While the movable plate rotates, the second motor is started, and the output end of the second motor drives the first lead screw to rotate. The first lead screw drives the slider and the spray head to move inside the movable plate, thereby increasing the distance between the spray head and the top of the aircraft tail. Thus, during the spraying of the top of the aircraft tail by the spray head, the paint ejected from the spray head and the top of the aircraft tail will not generate a large impact force, resulting in a large amount of paint splashing to other parts of the aircraft tail. This avoids the uneven paint phenomenon in other parts, and further improves the spraying effect;

[0020] 2. Through the provided protector, while the slider drives the spray head to move inward towards the movable plate, it drives the U-shaped rack to move synchronously through the connecting block, thereby driving the large gear to rotate. Subsequently, it drives the small gear to drive the straight gear to rotate towards the side of the aircraft tail through the first shaft. When the slider stops moving, the two baffles rotate in an inclined state on both sides of the aircraft tail, thereby blocking the paint that is ejected from the spray head and splashes upon impact with the top of the aircraft tail, thus preventing the splashed paint from flying to other parts of the aircraft tail and causing uneven paint application, thereby further improving the uniformity of aircraft tail spraying;

[0021] 3. Through the provided bending protection assembly, when the first shaft rotates, the spherical rod rotates from the lowest point to the highest point along the arc-shaped track at the end of the fitting block. Thus, under the action of the arc-shaped track, the spherical rod is pushed to drive the second shaft to move towards the first shaft, thereby driving the straight rack to move towards the straight gear through the connecting rod, and then driving the second lead screw to rotate. The second lead screw rotates to drive the power block to drive the roller to move towards the folding plate, thereby pushing the folding plate to rotate towards the inside of the baffle. When the baffle stops rotating, the roller is close to the side of the aircraft tail, thereby reducing the gap between the baffle and the aircraft tail, thus providing better blocking of the splashed paint.

[0038] Embodiment 1

[0039] Please refer to Figures 1 to 13 , this embodiment provides a spraying machine device for an aircraft tail wing, including: a spraying chamber 1, a door panel is installed on the side wall of the spraying chamber 1, a linear module 2 is installed on the inner top wall of the spraying chamber 1, a first motor 3 is installed on the outer wall of the spraying chamber 1, the execution end of the first motor 3 penetrates the outer wall of the spraying chamber 1 and is connected to a placement plate 4, and the placement plate 4 is rotatably connected to the spraying chamber 1. The execution end of the linear module 2 is installed with a U-shaped frame 5, and a plurality of electric telescopic rods 6 are symmetrically embedded at the bottom of the U-shaped frame 5. The execution end of the electric telescopic rod 6 is fixedly connected to a rectangular plate 7; a spray head 37, the spray head 37 is arranged at the bottom of the rectangular plate 7; an adjustment mechanism, which is respectively located at the bottom of the two rectangular plates 7 and is used to adjust the angle between the spray head 37 and the aircraft tail wing. The adjustment mechanism includes two fixed plates 8 respectively installed at the bottom of the rectangular plate 7. A rotating motor 38 is provided on the side wall of one of the fixed plates 8. The execution end of the rotating motor 38 penetrates the side wall of one of the fixed plates 8 and is connected to a movable plate 9. A second motor 10 is provided on one side of the movable plate 9. The execution end of the second motor 10 is installed with a first lead screw 11, and one end of the first lead screw 11 penetrates into the inner side of the movable plate 9 and is rotatably connected to the movable plate 9. A slider 12 is threadedly connected to the outer wall of the first lead screw 11. A spray head 37 is installed on the side of the slider 12 away from the first lead screw 11. The spray head 37 is externally connected to a feeding device through a pipeline inside the slider 12,

[0040] First, fix the aircraft tail wing to be sprayed on the placement plate 4 with a conveying device, then start the linear module 2 (the linear module here is a prior art and will not be elaborated too much here) and the electric telescopic rod 6 to drive the rectangular plate 7 at the bottom of the U-shaped frame 5 to move inside the spraying chamber 1. Then, send the paint from the pipeline inside the slider 12 into the nozzle 37 through the spraying device, and spray both sides of the aircraft tail wing with the two nozzles 37. When the spraying on both sides is completed, under the cooperation of the linear module 2 and the electric telescopic rod 6, the nozzle 37 is moved to the top of the aircraft tail wing. Subsequently, start the rotating motor 38 located at the top of the aircraft tail wing to drive the movable plate 9 to rotate 90 degrees on the fixed plate 8, so that the nozzle 37 rotates towards the top of the aircraft tail wing. While the movable plate 9 is rotating, start the second motor 10. The output end of the second motor 10 drives the first lead screw 11 to rotate. The first lead screw 11 drives the slider 12 and the nozzle 37 to move inside the movable plate 9, thereby increasing the distance between the nozzle 37 and the top of the aircraft tail wing. Thus, during the spraying of the top of the aircraft tail wing by the nozzle 37, there will be no large impact force between the paint ejected by the nozzle 37 and the top of the aircraft tail wing, causing a large amount of paint to splash onto other parts of the aircraft tail wing, thereby avoiding the phenomenon of uneven paint on other parts and improving the spraying effect.

[0041] Embodiment 2

[0042] The protector is located at the bottom of the rectangular plate 7 and is used to prevent the materials ejected by the nozzle 37 from splashing. The protector includes a chute 13 opened on the inner wall of the movable plate 9. A connecting block 14 is installed on one side of the movable plate 9, and the connecting block 14 is matched with the chute 13. A U-shaped rack 15 is installed on the side wall of the connecting block 14. Two connecting seats 16 are fixedly connected to one side of the movable plate 9, and the two connecting seats 16 are symmetrically arranged with respect to the center axis of the movable plate 9. A large gear 17 is rotatably connected to one side of each connecting seat 16, and the two large gears 17 mesh with the U-shaped rack 15. A small gear 18 meshes with one side of the large gear 17. A first shaft rod 19 is fixedly connected to one side of the small gear 18, and the first shaft rod 19 is rotatably connected to the inside of the connecting seat 16. A baffle 20 is fixedly connected to the outer wall of the first shaft rod 19.

[0043] While the slider 12 drives the nozzle 37 to move towards the inside of the movable plate 9, it drives the U-shaped rack 15 to move synchronously through the connecting block 14, thereby driving the large gear 17 to rotate. Further, it drives the small gear 18 to drive the straight gear 30 to rotate towards the side of the aircraft tail wing through the first shaft rod 19. When the slider 12 stops moving, the two baffles 20 rotate in an inclined state on both sides of the aircraft tail wing, thereby blocking the paint splashed by the impact of the paint ejected by the nozzle 37 on the top of the aircraft tail wing, thus avoiding the uneven paint caused by the splashed paint flying to other parts of the aircraft tail wing, and further improving the uniformity of the spraying of the aircraft tail wing.

[0044] When the spray head 37 is in a horizontal state to spray the side of the aircraft tail, the two baffles 20 initially unfolded at 30 degrees can also play the role of preventing the paint sprayed from the spray head 37 from hitting the aircraft tail to produce splashes.

[0045] Example 3

[0046] A bending protection component is installed on the side of the baffle 20 away from the connecting seat 16, and the bending protection component includes a second limit seat 35 fixedly connected to one end of the baffle 20, and a folding plate 27 is arranged on the inner side of the second limit seat 35, and both sides of the folding plate 27 are fixedly connected with a rotating shaft 36, and one end of the rotating shaft 36 passes through the inner side of the second limit seat 35 and is rotatably connected to the second limit seat 35, and a torsion spring 40 is installed between the folding plate 27 and the second limit seat 35, and the bending protection component also includes a first limit seat 28 fixedly connected to the end of the baffle 20, and the inner side of the first limit seat 28 is rotatably connected to the second screw rod 31, and the outer wall of the second screw rod 31 is threadedly connected to the power block 32, and one end of the power block 32 is rotatably connected to the roller 33, and the outer wall of the second screw rod 31 is fixedly connected to the spur gear 30, and the bottom of the spur gear 30 is meshed with a spur rack 29, and the inner side of the first shaft rod 19 is provided with a gear for dialing The toggle assembly for moving the movable spur rack 29 has a rectangular limit block 34 fixedly connected to the inner side of the first limit seat 28, and the toggle assembly includes a second shaft rod 22 slidably connected to the inner side of the first shaft rod 19, and the outer wall of the second shaft rod 22 is fixedly connected to the connecting rod 26, and the inner side of the first shaft rod 19 is provided with a through groove that penetrates to the outside and matches the connecting rod 26, one end of the connecting rod 26 is fixedly connected to the spur rack 29, and one end of the second shaft rod 22 penetrates to the outer wall of the first shaft rod 19 and is fixedly connected to a push block 23, and a connecting spring 24 is installed between the inner side of the push block 23 and the end of the first shaft rod 19, and the toggle assembly also includes a convex block 39 fixedly connected to one side of the movable plate 9, and the inner side of the convex block 39 is fixedly connected to a fitting block 25, and the end surface of the fitting block 25 is provided with an arc track, and one side of the push block 23 is fixedly connected to a spherical rod 41, and the spherical rod 41 is against the lowest point of the arc track;

[0047] When the first shaft 19 rotates, the spherical rod 41 rotates along the lowest point to the highest point of the arc track at the end of the fitting block 25, so that the spherical rod 41 is pushed to drive the second shaft 22 to move toward the first shaft 19 under the action of the arc track, thereby driving the spur rack 29 to move toward the spur gear 30 through the connecting rod 26, and then driving the second screw rod 31 to rotate. The second screw rod 31 rotates to drive the power block 32 to drive the roller 33 to move toward the folding plate 27, thereby pushing the folding plate 27 to rotate toward the inside of the baffle 20. When the baffle 20 stops rotating, the roller 33 is close to the side of the aircraft tail, thereby reducing the gap between the baffle 20 and the aircraft tail, thereby better blocking the splashing paint.

[0048] The following combines the above spraying machine device for an aircraft tail wing to provide a method for using a spraying machine for an aircraft tail wing, which specifically includes the following steps:

[0049] S1. First, fix the aircraft tail wing to be sprayed on the placement plate 4 with a conveying device, then start the linear module 2 and the electric telescopic rod 6 to drive the rectangular plate 7 at the bottom of the U-shaped frame 5 to move inside the spraying chamber 1, and then send the paint from the pipeline inside the slider 12 to the spray head 37 through the spraying device. The two spray heads 37 spray the two sides of the aircraft tail wing. After the two sides are sprayed, under the cooperation of the linear module 2 and the electric telescopic rod 6, the spray head 37 moves to the top of the aircraft tail wing. Subsequently, start the rotating motor 38 located at the top of the aircraft tail wing to drive the movable plate 9 to rotate 90 degrees on the fixed plate 8, so that the spray head 37 rotates towards the top of the aircraft tail wing. While the movable plate 9 is rotating, start the second motor 10. The output end of the second motor 10 drives the first lead screw 11 to rotate. The first lead screw 11 drives the slider 12 and the spray head 37 to move inside the movable plate 9, thereby increasing the distance between the spray head 37 and the top of the aircraft tail wing. Thus, during the spraying of the top of the aircraft tail wing by the spray head 37, there will be no large impact force between the paint sprayed by the spray head 37 and the top of the aircraft tail wing, causing a large amount of paint to splash onto other parts of the aircraft tail wing. This avoids the phenomenon of uneven paint on other parts, and further improves the spraying effect;

[0050] S2. When the slider 12 drives the spray head 37 to move towards the inside of the movable plate 9, it drives the U-shaped rack 15 to move synchronously through the connecting block 14, thereby driving the large gear 17 to rotate, and then driving the small gear 18 to drive the spur gear 30 to rotate towards the side of the aircraft tail wing through the first shaft 19. When the slider 12 stops moving, the two baffles 20 rotate in an inclined state on both sides of the aircraft tail wing, so as to block the paint splashed by the impact of the paint sprayed by the spray head 37 on the top of the aircraft tail wing, thereby avoiding the splashed paint flying to other parts of the aircraft tail wing and causing uneven paint. This further improves the uniformity of the spraying of the aircraft tail wing;

[0051] S3. When the spray head 37 sprays the side of the aircraft tail wing in a horizontal state, the two baffles 20 initially deployed at 30 degrees can also play the role of blocking the paint splashed by the impact of the paint sprayed by the spray head 37 on the aircraft tail wing;

[0052] S4. When the first shaft rod 19 rotates, the spherical rod 41 rotates from the lowest point to the highest point along the arc-shaped track at the end of the fitting block 25. Thus, under the action of the arc-shaped track, the spherical rod 41 is pushed to drive the second shaft rod 22 to move towards the first shaft rod 19. Thereby, the straight rack 29 is driven to move towards the spur gear 30 through the connecting rod 26, and further drives the second lead screw 31 to rotate. The second lead screw 31 rotates to drive the power block 32 to drive the roller 33 to move towards the folding plate 27, thereby pushing the folding plate 27 to rotate towards the inside of the baffle 20. When the baffle 20 stops rotating, the roller 33 is close to the side of the aircraft tail wing, thereby reducing the gap between the baffle 20 and the aircraft tail wing, so as to better block the splashing paint.

[0053] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.

5. A method for using a spraying machine for an aircraft tail fin, characterized in that, The spraying device for an aircraft tail wing according to claim 4 comprises the following steps: S1. First, fix the aircraft tail wing to be sprayed on the placement plate (4) with a conveying device. Then, start the linear module (2) and the electric telescopic rod (6) to drive the rectangular plate (7) at the bottom of the U-shaped frame (5) to move inside the spraying chamber (1). Then, send the paint from the pipeline inside the slider (12) into the spray head (37) through a spraying device, and spray both sides of the aircraft tail wing with the two spray heads (37). After spraying both sides, with the cooperation of the linear module (2) and the electric telescopic rod (6), move the spray head (37) to the top of the aircraft tail wing. Subsequently, start the rotating motor (38) located at the top of the aircraft tail wing to drive the movable plate (9) to rotate 90 degrees on the fixed plate (8), so that the spray head (37) rotates towards the top of the aircraft tail wing. While the movable plate (9) is rotating, start the second motor (10). The output end of the second motor (10) drives the first lead screw (11) to rotate. The first lead screw (11) drives the slider (12) and the spray head (37) to move inside the movable plate (9), thereby increasing the distance between the spray head (37) and the top of the aircraft tail wing. Thus, during the spraying of the top of the aircraft tail wing by the spray head (37), there will be no large impact force between the paint ejected by the spray head (37) and the top of the aircraft tail wing, causing a large amount of paint to splash onto other parts of the aircraft tail wing, thereby avoiding the phenomenon of uneven paint on other parts and further improving the spraying effect; S2. When the slider (12) drives the spray head (37) to move towards the inner side of the movable plate (9), it drives the U-shaped rack (15) to move synchronously through the connecting block (14), thereby driving the large gear (17) to rotate, and further driving the small gear (18) to drive the spur gear (30) to rotate towards the side of the aircraft tail wing through the first shaft rod (19). When the slider (12) stops moving, the two baffles (20) rotate in an inclined state on both sides of the aircraft tail wing, so as to block the paint splashed by the impact of the paint ejected by the spray head (37) on the top of the aircraft tail wing, thereby avoiding the splashed paint flying onto other parts of the aircraft tail wing and causing uneven paint, thereby further improving the uniformity of the aircraft tail wing spraying; S3. When the spray head (37) sprays the side of the aircraft tail wing in a horizontal state, the two baffles (20) initially deployed at 30 degrees can also play the role of blocking the paint splashed by the impact of the paint ejected by the spray head (37) on the aircraft tail wing; S4. When the first shaft rod (19) rotates, the spherical rod (41) rotates from the lowest point to the highest point along the arc-shaped track at the end of the fitting block (25). Thus, under the action of the arc-shaped track, the spherical rod (41) is pushed to drive the second shaft rod (22) to move towards the first shaft rod (19). Then, the connecting rod (26) drives the straight rack (29) to move towards the spur gear (30), further driving the second lead screw (31) to rotate. The second lead screw (31) rotates to drive the power block (32) to drive the roller (33) to move towards the folding plate (27), thus pushing the folding plate (27) to rotate towards the inside of the baffle (20). When the baffle (20) stops rotating, the roller (33) is close to the side of the aircraft tail wing, thereby reducing the gap between the baffle (20) and the aircraft tail wing, so as to better block the splashing paint.
