TECHNICAL FIELD
[0001] The present application belongs to the technical field of paint spraying fixing of aircraft hole parts, and relates to a flexible paint spraying tray for fixing hole parts. BACKGROUND
[0002] At present, a large number of hole parts need to be painted in the aircraft manufacturing industry. The hole parts have various types, large quantity, various sizes and complex shapes. The conventional production method is to use adhesive tape to fix the parts on a paint spraying tray with a screen for paint spraying treatment.
[0003] The use of adhesive tape to fix the parts for paint spraying treatment can cause the following problems:
[0004] (1) The parts need to be painted on both sides. After the parts are fixed on the paint spraying tray using adhesive tape and painted on one side, the parts need to be turned over. Since the adhesive tape has been covered with the paint layer, the adhesive tape needs to be replaced before the parts are fixed again, which increases the labor intensity of the operator and affects the production efficiency.
[0005] (2) The use of adhesive tape to fix the parts can cause a large amount of consumption of adhesive tape, which is expensive and has high production cost.
[0006] (3) The front surface of the parts needs to be anodized before paint spraying. It is found through experiments that the paint layer on the anodized surface in contact with the adhesive tape is greatly reduced in adhesion when the parts are painted using adhesive tape, which can easily cause quality problems such as paint peeling of the parts, and the parts need to be reworked, which restricts the production efficiency. SUMMARY
[0007] In view of the problems in the prior art, the present application provides a flexible paint spraying tray for fixing hole parts, which can quickly fix the position of the parts on the paint spraying tray through simple operation by using the hole positions of the parts, avoid the use of adhesive tape to fix the parts, reduce the fixing time of the parts, reduce the number of adhesive tapes used, reduce the production cost, improve the product quality, and improve the production efficiency.

[0013] Further, the holes at the two ends of the rotating cross beam 5 and the threaded holes at the bottom of the U-shaped support bracket 4 are connected by butterfly bolts, for quick assembly and disassembly of the rotating cross beam 5 and independent rotation, to realize quick updating of the upper surface of the rotating cross beam 5.

[0036] The present invention will be further described below with reference to specific embodiments.
[0037] Example
[0038] A paint tray for flexibly fixing perforated parts, the paint tray comprising a tray frame 1, an L-shaped fixing plate 2, guide wheels 3, a U-shaped support 4, a rotating crossbeam 5, and an annular foam 6, as shown. Figure 1 As shown.
[0039] The pallet frame 1 is a rectangular frame structure made of stainless steel. It has internal cross-shaped support columns, and several L-shaped fixing pieces 2 are installed on its four sides. Figure 2 As shown, triangular stainless steel ribs are welded to the upper and lower surfaces of the inner sides of the four corners to ensure the overall structural stability of the pallet frame 1, preventing deformation of the load-bearing parts over long periods, and allowing it to support heavier parts for painting. Figure 3 As shown; several U-shaped support brackets 4 are welded at equal intervals along the long side of the inner side of the pallet frame 1. The U-shaped support brackets 4 are arranged in pairs on both sides of the pallet frame 1. Their interiors are rectangular grooves used to hold the rotating crossbeam 5. Each U-shaped support bracket 4 has a threaded hole at its bottom center. Figure 5The tray frame 1 is provided with four guide wheels 3 outside the four corners, which can rotate 360° around the bolts. The paint tray is used for automatic transmission on the double-speed chain, as shown in Figure 4
[0040] The rotating beam 5 is a cuboid column structure, which is made of aluminum alloy plate welding. The cross section is square, and the cross section size matches the width of the groove structure of the U-shaped support 4. The rotating beam 5 is provided with several rotating beams 5, and each rotating beam 5 is placed on the two U-shaped support 4 on the two sides of the tray frame 1. Holes are made at the center of the four faces of the two ends of the rotating beam 5, and the positions of the holes are corresponding to the threaded holes at the bottom of the U-shaped support 4. As shown in Figure 6 The rotating beam 5 is fixed on the U-shaped support 4 by the butterfly-shaped bolt, which is used for quick disassembly and rotation of the rotating beam 5, and realizes the quick update of the upper surface of the rotating beam 5, as shown in Figure 7
[0041] The annular foam cotton 6 is shown in Figure 8 It is a hollow column flexible structure, and the inner hole cross section is square, and the inner diameter is slightly smaller than the cross section size of the rotating beam 5. The length of the annular foam cotton 6 is less than the rotating beam 5. The annular foam cotton 6 is sleeved on the rotating beam 5, so that the holes at the two ends of the rotating beam 5 are exposed, so as to avoid the connection position of the rotating beam 5 and the U-shaped support 4, as shown in Figure 9 Because the foam cotton has good deformation resilience, the annular foam cotton 6 is sleeved on the rotating beam 5, which can ensure the stable fixation of the foam cotton on the moving beam without the help of additional structure.
[0042] The use method of the paint tray is illustrated by taking the longeron part in the Airbus project as an example. The longeron part is 1200mm long, and 12 holes are uniformly distributed in the middle. The hole diameter is 0.4mm. The longeron part is placed on the paint tray, and two nails are used to fix the annular foam cotton 6 through the two holes of the longeron part. For gaskets, angle bars and other parts, one nail can be used to fix the annular foam cotton 6 through one hole. After the fixation is completed, paint spraying is carried out. After the first surface is painted, the longeron part is directly turned over, the hole position is aligned with the original nail position, and the part is directly placed, so as to realize the quick fixation of the part. When the upper surface of the annular foam cotton 6 is covered with thick paint layer and cannot continue to use the nail to fix the part, the butterfly-shaped bolt at the two ends of the rotating beam 5 needs to be loosened, the rotating beam 5 is rotated 90° around the axis, the new surface of the annular foam cotton 6 is upward, the butterfly-shaped bolt is tightened, and the nail is used to fix the part.
[0043] The above embodiments only express the implementation ways of the present application, but cannot be understood as a limitation to the scope of the patent of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
