[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: 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; S2, when the slider drives the spray head to move toward the inner side of the movable plate, the U-shaped rack is driven to move synchronously through the connecting block, thereby driving the large gear to rotate, and then driving the small gear to drive the spur gear to rotate toward the side of the aircraft tail through the first shaft rod. When the slider stops moving, the two baffles are rotated in an inclined state on both sides of the aircraft tail, thereby blocking the paint splashed by the spray head and the top of the aircraft tail, thereby preventing the splashed paint from flying to other parts of the aircraft tail and causing uneven paint, thereby further improving the uniformity of the aircraft tail spraying; S3, when the spray head is in a horizontal state to spray the side of the aircraft tail, the two baffles initially unfolded at 30 degrees can also play the role of preventing the paint sprayed from the spray head from hitting the aircraft tail to produce splashes; S4. When the first shaft rotates, the spherical rod rotates along the lowest point of the arc track at the end of the mating block to the highest point, so that the spherical rod is pushed to drive the second shaft to move toward the first shaft under the action of the arc track, thereby driving the spur rack to move toward the spur gear through the connecting rod, and then driving the second screw rod to rotate. The second screw rod rotates to drive the power block to drive the roller to move toward the folding plate, thereby pushing the folding plate to rotate toward 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, thereby better blocking the splashing paint.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the adjustment mechanism, the linear module and the electric telescopic rod cooperate to move the nozzle to the top of the aircraft tail wing, and then start the rotating motor located at the top of the aircraft tail wing to drive the movable plate to rotate 90 degrees on the fixed plate, so that the nozzle rotates toward the top of the aircraft tail wing. While the movable plate rotates, start the second motor, and the output end of the second motor drives the first screw to rotate. 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 sprays 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, causing 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; 2. Through the set protector, the slider drives the nozzle to move to the inside of the movable plate and drives the U-shaped rack to move synchronously through the connecting block, thereby driving the large gear to rotate, and then driving the small gear to drive the spur gear to rotate to the side of the aircraft tail through the first shaft rod. 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 nozzle and the top of the aircraft tail, thereby preventing the splashed paint from flying to other parts of the aircraft tail and causing uneven paint, thereby further improving the uniformity of the aircraft tail spraying; 3. By setting up the bending protection component, when the first shaft rod rotates, the spherical rod rotates along the lowest point to the highest point of the arc track at the end of the fitting block, so that the spherical rod is pushed to drive the second shaft rod to move toward the first shaft rod under the action of the arc track, thereby driving the spur rack to move toward the spur gear through the connecting rod, and then driving the second screw rod to rotate. The second screw rod rotates to drive the power block to drive the roller to move toward the folding plate, thereby pushing the folding plate to rotate toward 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, thereby better blocking the splashing paint.

When the slider 12 drives the spray head 37 to move toward the inside of the movable plate 9, the U-shaped rack 15 is driven 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 toward the side of the aircraft tail through the first shaft 19. When the slider 12 stops moving, the two baffles 20 are rotated in an inclined state on both sides of the aircraft tail, thereby blocking the paint splashed by the spray head 37 and the top of the aircraft tail, thereby preventing the splashed paint from flying to other parts of the aircraft tail and causing uneven paint, thereby further improving the uniformity of the aircraft tail spraying; S3, 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; S4.

9. A method for using a spraying machine for an aircraft tail, characterized in that: The spraying device for an aircraft tail wing according to claim 7 comprises the following steps: S1. First, the aircraft tail to be sprayed is fixed on the placement plate (4) by a conveying device, then the linear module (2) and the electric telescopic rod (6) are started to drive the rectangular plate (7) at the bottom of the U-shaped frame (5) to move inside the spraying chamber (1), and then the paint is sent from the pipeline inside the slider (12) to the spray head (37) by the spraying device, and the two spray heads (37) spray the two sides of the aircraft tail. When the spraying of both sides is completed, the linear module (2) and the electric telescopic rod (6) are cooperated to move the spray head (37) to the top of the aircraft tail, and then the rotating motor (38) located at the top of the aircraft tail is started to drive the movable plate (9) to rotate on the fixed plate (8). The movable plate (9) is rotated by 90 degrees, so that the spray head (37) rotates toward the top of the aircraft tail wing. When the movable plate (9) rotates, the second motor (10) is started, and the output end of the second motor (10) drives the first screw rod (11) to rotate. The first screw rod (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. When the spray head (37) sprays the top of the aircraft tail wing, the paint sprayed by the spray head (37) and the top of the aircraft tail wing will not generate a large impact force, causing a large amount of paint to splash onto other parts of the aircraft tail wing, thereby avoiding uneven paint in other parts, thereby improving the spraying effect; S2, when the slider (12) drives the spray head (37) to move toward the inside of the movable plate (9), the U-shaped rack (15) is driven 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 toward the side of the aircraft tail 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, thereby blocking the paint sprayed by the spray head (37) and colliding with the top of the aircraft tail to generate splashes, thereby preventing the splashed paint from flying to other parts of the aircraft tail and causing uneven paint, thereby further improving the uniformity of the aircraft tail spraying; S3, when the spray head (37) is in a horizontal state and is spraying the side of the aircraft tail wing, the two baffles (20) initially spread out at a thirty-degree angle can also play a role in preventing the paint sprayed from the spray head (37) from hitting the aircraft tail wing and generating splashes; S4. When the first shaft (19) rotates, the spherical rod (41) rotates along the lowest point of the arc track at the end of the fitting block (25) toward the highest point, so that the spherical rod (41) is pushed under the action of the arc track to drive the second shaft (22) to move toward the first shaft (19), thereby driving the spur rack (29) to move toward the spur gear (30) through the connecting rod (26), thereby 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 splashed paint.
