Description

Technical Field

[0001] This utility model belongs to the field of spray painting and hoisting technology, and relates to an automatic spray painting and hoisting bracket for deep blind hole projectile bodies of attack missiles. Background Technology

[0002] The deep blind hole projectile body for attack-tank missiles requires painting both its inner and outer surfaces. A problem arises: the projectile body is heavy, its outer surface is smooth, and there is no clamping position, making automated painting of both surfaces difficult. Furthermore, the closed-end deep hole structure, due to its unique design, easily leads to paint accumulation or dripping on the inner wall during painting. This necessitates inverting the part (opening downwards) to allow excess paint to drain naturally under gravity, preventing paint buildup at the bottom of the hole. Traditional methods involve manual or semi-automatic operation, which is time-consuming, labor-intensive, and does not meet environmental and safety requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic spraying and hoisting bracket for deep blind hole projectiles.

[0004] The automatic spraying and hoisting bracket for deep blind hole projectiles of this utility model includes a drive motor and a hoisting rod. A transmission component connected to the drive motor is rotatably connected to the hoisting rod. A hook is fixedly connected to the transmission component. A hanger is fixedly connected to the bottom of the hook. A large tray is fixedly connected to the bottom of the hanger. A fixing component is provided on the large tray. A positioning component adapted to the fixing component is movably connected to the hanger. The positioning component includes a large baffle that is slidably connected to the bracket, and the large baffle has positioning holes.

[0005] The fixing component also includes a small baffle, which is connected to the large baffle by a pin and has a slot adapted to the bracket and a pin hole adapted to the pin.

[0006] The fixing component includes a small tray that snaps into the large tray, a fixing sleeve that is fixedly connected to the small tray, and the fixing sleeve is threaded. The center of the large tray, the small tray and the fixing sleeve are all through holes.

[0007] The fixing component includes a small tray that is fixedly connected to the large tray, and a fixing sleeve is fixedly connected to the small tray. The center of the large tray, the small tray and the fixing sleeve are all through holes.

[0008] The bracket has a first connecting ear at the bottom and a second connecting ear corresponding to the first connecting ear is fixedly connected to the large tray. The first connecting ear and the second connecting ear are connected by fixing bolts.

[0009] The transmission assembly includes a drive wheel fixedly connected to a drive motor, a rotating wheel fixedly connected to a hook, and a rotating disc rotatably connected to a lifting rod via several connecting bolts. The lifting rod is equipped with a bearing for supporting the rotation of the rotating disc.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the internal and external threads of the part itself to fix the workpiece on a hanger. The hook rotates automatically under the drive of a motor, while the spray gun only needs to move up and down to complete the automatic spraying of the internal and external surfaces. This achieves uniform and complete coating, improves spraying quality, and reduces labor intensity. Attached Figure Description

Detailed Implementation

[0013] Example 1 like Figures 1-5As shown, the automatic spraying and hoisting bracket for deep blind hole projectiles of this utility model includes a drive motor 14 and a hoisting rod 19. A transmission component connected to the drive motor 14 is rotatably connected to the hoisting rod 19. A hook 12 is fixedly connected to the transmission component. A bracket 1 is fixedly connected to the bottom of the hook 12. A large tray 9 is fixedly connected to the bottom of the bracket 1. A fixing component is provided on the large tray 9. A positioning component adapted to the fixing component is movably connected to the bracket 1. The positioning component includes a large baffle 2 slidably connected to the bracket 1. The large baffle 2 has a positioning hole 20. The fixing component also includes a small baffle 4. The small baffle 4 is connected to the large baffle 2 by a pin 3. The large baffle 2 has a slot 22 adapted to the bracket 1 and a pin hole 21 adapted to the pin 3. The small baffle 4 and the pin 3 can be used to mount the large baffle 2. The large baffle 2 is designed for easy replacement of workpieces 5 with different sizes to accommodate different sizes. The fixing component includes a small tray 11 fixedly connected to the large tray 9. A fixing sleeve 10 is fixedly connected to the small tray 11. The center of the large tray 9, the small tray 11, and the fixing sleeve 10 are all through holes. The workpiece 5 is fixed on the large tray 9 by threading it onto the fixing sleeve 10. Then, the workpiece 5 is positioned and fixed by inserting it into the top of the positioning hole 20 on the large baffle 2. The transmission component includes a drive wheel 13 fixedly connected to the drive motor 14. The drive wheel 13 is driven by a rotating wheel 15 fixedly connected to the hook 12. The rotating wheel 15 is fixedly connected to a rotating disk 17 rotatably connected to the lifting rod 19 by several connecting bolts 16. The lifting rod 19 is provided with a bearing 18 for supporting the rotation of the rotating disk 17.

[0014] Example 2 Unlike other embodiments, the fixing component in this embodiment includes a small tray 11 that snaps into the large tray 9. A fixing sleeve 10 is fixedly connected to the small tray 11, and the fixing sleeve 10 is threaded. The center of the large tray 9, the small tray 11, and the fixing sleeve 10 are all through holes. The bottom of the small tray 11 is provided with a boss corresponding to the through hole in the center of the large tray 9, so that the small tray 11 can be snapped into the large tray 9 and can be quickly loaded and unloaded. The positioning hole 20 of the large baffle 2 is also provided with an internal thread that matches the top of the workpiece 5. The positioning hole 20 is used to position and fix the workpiece 5 by connecting the internal thread of the positioning hole 20 with the external thread of the workpiece 5 at the top of the workpiece 5. At the same time, the external thread on the fixing sleeve 10 is used to connect with the internal thread at the bottom of the workpiece 5 to achieve double fixing.

By rotating the workpiece 5, the external thread on the top of the workpiece 5 is threaded into the internal thread in the positioning hole 20 of the large baffle 2 to fix the workpiece 5. At that time, start the drive motor 14, and the hanger 1 is rotated through the drive wheel 13 and the transmission wheel. At this time, the spray gun can move up and down on the inner and outer surfaces of the workpiece 5 to realize the automatic spraying operation of the workpiece 5.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the internal and external threads of the part itself to fix the workpiece 5 onto the hanger 1. The hook 12 rotates automatically under the drive of the motor 14. The spray gun only needs to move up and down to complete the automatic spraying of the internal and external surfaces. This achieves uniform and complete coating, improves spraying quality, and reduces labor intensity.
