Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to a spraying device for wing production and processing. Background Art

[0002] The wing is the main component of an aircraft for generating lift. It is generally divided into two left and right wing surfaces. The wing is one of the important components of an aircraft and is installed on the fuselage. Its most important function is to generate lift and form good stability and maneuverability together with the tail. In order to ensure the long-term use of the wing and prevent it from being damaged by corrosion, a spraying device is required to spray or topcoat the wing during the manufacturing process. Current spraying devices usually place the wing on a support frame, or hang it on a hook, or clamp it with a clamping device, and then spray it.

[0003] The spraying device usually consists of a sprayer and a clamping assembly. When spraying the wing, the wing is clamped by the clamping assembly, and the spraying work is completed by the sprayer. During use, usually only one side of the wing can be clamped, which causes deviation when the wing is fixed when spraying the other side, making it difficult to flip the wing, resulting in different spray thicknesses and reduced effect of spraying the wing.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing spraying devices for wing production and processing on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1 to 3 , the present invention provides a technical solution: a spraying device for wing production and processing, including a main body mechanism 1, the main body mechanism 1 includes a workbench 11, a moving frame 12 is arranged on the top of the workbench 11, a connecting block 13 is slidably connected to the inner cavity of the moving frame 12, a sprayer 14 is fixedly installed at the bottom of the connecting block 13, and a flipping mechanism 2 is arranged on the top of the workbench 11; The flipping mechanism 2 includes a flipping unit 21, the flipping unit 21 is arranged on the top of the workbench 11, and the flipping unit 21 is used to flip the wing.

[0023] As a further limitation of the flipping mechanism 2 of the present invention, the flipping unit 21 includes a fixing plate 2101, and the fixing plate 2101 is fixedly installed on the top of the workbench 11. The number of the fixing plates 2101 is two. A rotating rod 2102 is rotatably connected to the inner wall of the fixing plate 2101. Electric grippers 2104 are fixedly installed at opposite ends of the two rotating rods 2102. A placing table 2105 is fixedly installed on the top of the workbench 11. The number of the placing tables 2105 is two. An electric push rod 2106 is fixedly installed inside the placing table 2105. A first toothed plate 2107 is fixedly installed at the telescopic end of the electric push rod 2106. Full gears 2108 are fixedly installed at opposite ends of the two rotating rods 2102. The teeth of the full gears 2108 mesh with the teeth of the first toothed plate 2107. By providing the flipping unit 21, through the cooperation of the first toothed plate 2107 and the full gears 2108, the fixing angle of the wing can be changed, so that the angle adjustment time during wing spraying can be reduced, multi-angle adjustment of the wing can be achieved, thereby increasing the efficiency of wing spraying, and at the same time avoiding errors caused by disassembling the wing.

[0024] A guiding groove 2109 is formed in the top of the placing table 2105. A guiding block 2110 is fixedly installed at the bottom of the first toothed plate 2107. The inner cavity of the guiding groove 2109 is slidably connected to the surface of the guiding block 2110. Through the sliding connection between the guiding groove 2109 and the guiding block 2110, the movement of the first toothed plate 2107 can be guided, so that the first toothed plate 2107 moves horizontally.

[0025] Two stoppers 2111 are fixedly installed on the surfaces of the two rotating rods 2102. The opposite sides of the two stoppers 2111 are in contact with the surface of the fixing plate 2101. By providing the stoppers 2111, the opposite sides of the two stoppers 2111 are in contact with the surface of the fixing plate 2101, which can prevent the rotating rod 2102 from sliding in the inner cavity of the fixing plate 2101 and ensure the stability of the rotating rod 2102 during operation.

[0026] A support ring 2103 is fixedly installed on the top of the placing table 2105. The inner side of the support ring 2103 is in contact with the surface of the electric push rod 2106. By providing the support ring 2103, the support ring 2103 can support the bottom of the electric push rod 2106, thereby realizing the support of the electric push rod 2106 and increasing the stability of the electric push rod 2106.

[0027] The specific implementation of this embodiment is as follows: The user places the wing on the top of the workbench 11, starts the electric gripper 2104 through an external power supply, fixes the position of the wing through the electric gripper 2104. The moving frame 12 consists of a driver, a screw rod and the moving frame 12. The driver and the screw rod are supported by the moving frame 12. Through the threaded connection between the screw rod and the connecting block 13, the movement of the connecting block 13 can be realized, and then the spraying device 14 can be driven to move. The spraying device 14 is connected to an external material tank, and the paint in the material tank is transported to the spraying device 14 through a paint pump. Through the spraying of the spraying device 14 and the movement of the connecting block 13, the spraying effect on one side of the wing is achieved. When spraying the side or back of the wing, the electric push rod 2106 is started through an external power supply, and the first toothed plate 2107 is pushed to move through the electric push rod 2106. Through the engagement between the first toothed plate 2107 and the full gear 2108, the rotating rod 2102 can be driven to rotate. The position of the rotating rod 2102 is limited by the fixing plate 2101, and the rotating rod 2102 can rotate at the same position, thereby driving the electric gripper 2104 to rotate. Through the moving degree of the first toothed plate 2107, one side or the back of the wing can be placed above, and the spraying device 14 is used for spraying, thus realizing the spraying of the back and side of the wing, reducing the spraying time of the wing and increasing the work efficiency.

[0028] Embodiment 2: Please refer to Figure 1 , the present invention provides a technical solution: A spraying device for wing production and processing. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The flipping mechanism 2 further includes an adjusting unit 22. The adjusting unit 22 is arranged on the top of the workbench 11, and the adjusting unit 22 is used to adjust the height of the spraying device 14.

[0029] As a further limitation of the flipping mechanism 2 of the present invention, the adjusting unit 22 includes a damping telescopic rod 2201. The damping telescopic rod 2201 is fixedly installed on the top of the workbench 11. The telescopic end of the damping telescopic rod 2201 is fixedly connected to the top of the moving frame 12. A second toothed plate 2202 is fixedly installed inside the moving frame 12. A half gear 2203 is fixedly installed on one side of the full gear 2108. The teeth of the half gear 2203 cooperate with the teeth of the second toothed plate 2202. By setting the adjusting unit 22, the height of the spraying device 14 can be flexibly changed according to the spraying requirements of different surfaces of the wing. While ensuring that the spraying height always remains consistent, the phenomenon of uneven spraying caused by height differences is reduced, and the spraying quality of the wing is improved.

[0030] A spring 2204 is sleeved on the surface of the damping telescopic rod 2201. One end of the spring 2204 is fixedly connected to the top of the workbench 11, and the other end of the spring 2204 is fixedly connected to the top of the moving frame 12. By arranging the spring 2204, during the upward movement of the moving frame 12, the spring 2204 can be driven to extend. During the downward movement of the moving frame 12, the reaction force of the spring 2204 cooperates with the damping force of the damping telescopic rod 2201 to buffer the downward movement of the moving frame 12 and reduce the vibration of the workbench 11.

[0031] The specific implementation manner of this embodiment is as follows: During the process of the first toothed plate 2107 driving the full gear 2108 to rotate, the rotation of the full gear 2108 will drive the half gear 2203 to rotate accordingly. Since the teeth of the half gear 2203 mesh with the teeth of the second toothed plate 2202, the rotation of the half gear 2203 can push the moving frame 12 upward. When spraying the side of the wing, through this transmission mechanism, the moving frame 12 can be moved to the highest position, thereby ensuring that the spraying height of the sprayer 14 always remains consistent, effectively avoiding the problem of uneven spraying effects on different parts of the wing due to height differences, and significantly improving the qualification rate of wing spraying. When the wing rotates to the back side, the teeth of the half gear 2203 will separate from the teeth of the second toothed plate 2202. Under the action of the self-weight of the moving frame 12, it can move downward. During the downward movement, through the damping force generated by the retraction of the damping telescopic rod 2201 and the reaction force generated by the extension of the spring 2204, the downward movement of the moving frame 12 can be buffered, so that the moving frame 12 moves downward slowly, reducing the vibration of the workbench 11, and then realizing the reset of the sprayer 14. It can change the height of the sprayer 14 according to the spraying of different sides of the wing, thereby ensuring that the spraying height remains consistent while reducing spraying unevenness caused by height differences.

[0032] Embodiment 3: Please refer to Figure 2 、 Figure 4 、 Figure 5 、and Figure 6 and Figure 7 , the present invention provides a technical solution: a spraying device for wing production and processing. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A drying mechanism 3 is arranged inside the workbench 11, and the drying mechanism 3 is used for drying the sprayed wing.

[0033] As a further limitation of the air-drying mechanism 3 of the present invention, the air-drying mechanism 3 includes a moving hole 312 opened at the top of the workbench 11. The inner wall of the moving hole 312 is rotatably connected to a lead screw 31. One end of the lead screw 31 penetrates to the outside of the workbench 11. A motor 32 is fixedly installed on one side of the workbench 11. The output end of the motor 32 is fixedly connected to one end of the lead screw 31. A moving block 33 is slidably connected to the inner cavity of the moving hole 312. A placement plate 34 is fixedly installed on the surface of the moving block 33. Ventilation holes 35 are opened in the inner wall of the placement plate 34. Electric fans 36 are fixedly installed on the inner walls of the ventilation holes 35. A ventilation box 37 is fixedly communicated with the top of the placement plate 34. A flow dividing plate 38 is fixedly installed on the inner wall of the ventilation box 37. The number of the flow dividing plates 38 is several. By setting the air-drying mechanism 3, with the cooperation of components such as the full gear 2108 and the first toothed plate 2107, the wing is flipped, the spraying surface can be adjusted to a proper position, and the height of the sprayer 14 can be flexibly adjusted; during air-drying, the motor 32 drives the lead screw 31 to move the placement plate 34 and the ventilation box 37. The electric fans 36 cooperate with the flow dividing plates 38 to generate uniform air flow, which can uniformly air-dry the wing, effectively ensuring the quality of wing spraying and air-drying.

[0034] A limiting groove 39 is opened on the inner wall of the moving hole 312. A limiting block 310 is fixedly installed on the surface of the moving block 33. The surface of the limiting block 310 is slidably connected to the inner cavity of the limiting groove 39. Through the sliding connection between the limiting groove 39 and the limiting block 310, the movement of the moving block 33 can be guided to avoid the deflection of the moving block 33 and make the moving block 33 move horizontally.

[0035] Baffles 311 are fixedly installed on the opposite sides of the two fixing plates 2101. The baffles 311 are used in cooperation with the ventilation box 37. By setting the baffles 311, when the ventilation box 37 is not working, the top of the ventilation box 37 can be blocked to prevent the paint from entering the inner cavity of the ventilation box 37.

[0036] The specific implementation mode of this embodiment is as follows: When the spraying of one surface of the wing by the sprayer 14 is completed, through the cooperation of the full gear 2108 and the first toothed plate 2107, the sprayed surface is placed below. The motor 32 is started through an external power supply. The motor 32 drives the lead screw 31 to rotate. Through the rotation of the lead screw 31, the moving block 33 can be driven to slide in the inner cavity of the moving hole 312, thereby driving the placement plate 34 and the ventilation box 37 to move. During the movement, the electric fans 36 are started through an external power supply. Through the rotation of the electric fans 36, the air flow inside the ventilation box 37 can be accelerated to generate air flow. The air flow is divided by the flow dividing plates 38, and the air flow can be evenly blown to the surface of the sprayed wing, thereby uniformly air-drying the wing and ensuring the air-drying quality after wing spraying.
