Description

Technical Field

[0001] This utility model relates to an arc-shaped skin spray painting hanger, belonging to the field of tooling and fixture manufacturing. Background Technology

[0002] Aircraft parts are diverse and complex in shape, requiring high precision in the painting process. This is especially true for curved skin parts, which are large and non-flat, making painting particularly challenging. Current methods involve fixing the curved skin onto a trolley and feeding it into the paint booth. The existing paint booth uses a negative pressure water vortex structure, with compressed air supplied from top to bottom and flowing water below. When the paint mist is sprayed from the spray gun, it settles into the water below the spray booth under the influence of the compressed air.

[0003] In existing painting methods, because the floor of the transport vehicle is sealed, the paint mist cannot fall into the water under negative pressure; it can only fall onto the floor. When painting the bottom of the curved skin, the paint mist that falls onto the floor is blown up by the spray gun under compressed air, causing quality problems such as powdering, roughness, or particles in the paint layer of the curved skin. Furthermore, the bottom of the curved skin is in contact with the transport vehicle, making it impossible to reach during the initial painting process. Touch-up painting must be done after the curved skin has been painted and dried. This touch-up painting process requires the curved skin to be laid flat on the transport vehicle, increasing the production cycle. Moreover, the transfer process requires multiple people to operate, making the operation difficult and prone to quality problems such as bumps and knocks. Utility Model Content

[0004] The purpose of this utility model is to provide an arc-shaped skin painting hanger, which solves the existing problems of arc-shaped skin painting, reduces the difficulty of operation, improves applicability, reduces the production cycle, and ensures the quality of parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an arc-shaped skin spray painting hanger, the hanger comprising a spray painting hanger body, a hanging rod, and a hanging rod moving part; the bottom of the spray painting hanger body is placed on the ground, and the top is used to suspend the hanging rod; the hanging rod is horizontally suspended on the spray painting hanger body through the hanging rod moving part for hoisting the skin; there are two hanging rod moving parts, which are respectively installed at opposite ends of the spray painting hanger body.

[0006] Preferably, the main body of the paint spraying hanger is made of square steel and pipe welded together.

[0007] Preferably, a directional wheel and a swivel wheel are installed at the bottom of the paint spraying hanger body; wherein, the directional wheel is installed at one end of the paint spraying hanger body, and the number of swivel wheels is three, which are installed at the other end and the middle of the paint spraying hanger body respectively.

[0008] Preferably, the hanger rod adopts a triangular structure and is welded from pipes.

[0009] Preferably, the movable part of the boom includes a support, rollers, and a steel cable; there are two supports, which are fixed at both ends of the paint spraying frame body to support and fix the rollers; there are two rollers, which are used to tighten and release the steel cable and have a locking function; one end of the steel cable is wound around the roller, and the other end passes through the movable part and connects to the boom; the movable part is installed on the top of the paint spraying frame body, and when the steel cable is subjected to external force, it moves on the movable part and the rollers, thereby causing the boom to move up and down.

[0010] Compared with the prior art, the present invention has the following advantages: 1. When using this hanger for painting, excess paint mist can be smoothly deposited into the flowing water below the paint booth under negative pressure, preventing paint mist from being blown up again after falling on the surface of the transfer vehicle, causing defects such as powdering, roughness or particles in the paint layer of the arc-shaped skin. 2. The painting process can be completed in one go on this hanger without having to move it again. Touch-up painting of the bottom is performed, which reduces the number of steps, improves the painting efficiency of parts, and avoids damage to the skin during the transfer process. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model; Figure 1 In the middle, 1. swivel casters; 2. fixed casters; 3. main body of the hanger; 4. support; 5. rollers; 6. steel cables; 7. movable parts; 8. hanger rods. Detailed Implementation

[0012] It should be noted that the terms "upper," "lower," "left," "right," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use. They are only used to facilitate the description of this utility model and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0013] The following is in conjunction with the appendix Figure 1 The present invention is further described in detail as follows: an arc-shaped skin spray painting hanger includes pulleys, a hanger body 3, a hanger rod 8, and a hanger rod moving part; wherein, the pulleys include universal wheels 1 and directional wheels 2; the hanger rod moving part includes a support 4, rollers 5, steel cables 6, and a movable part 7.

[0014] In a preferred embodiment, the casters 1 and directional casters 2 are installed at the bottom of the hanger body 3, allowing the entire frame to be moved for easy transportation and transfer between processes. One end and the middle of the hanger body 3 use casters 1, while the other end uses directional casters 2. This allows for direct mounting onto the hanger body 3 after surface treatment, facilitating transfer during subsequent painting, drying, and other processes, thus reducing labor intensity. The casters 1 at the bottom middle of the hanger body 3 do not hinder its movement and also provide some load-bearing capacity, preventing deformation of the painting hanger body 3 due to weight and extending its service life.

[0015] As a preferred embodiment of this invention, the main body 3 of the hanger is made of square steel and pipes welded together, which increases the overall load-bearing capacity.

[0016] As a preferred embodiment of this invention, the hanger adopts a triangular structure and is made of welded pipes. The skin is suspended on the hanger to achieve hanging spraying. During hoisting, aluminum wire is passed through the hoisting lugs and tied to different positions of the triangular hanger according to the curvature of the skin to ensure that the skin will not deform after hoisting.

[0017] In a preferred embodiment of this invention, the steel cable 6 and the movable part 7 are connected to the support 4 and the roller 5. The support 4 and the roller 5 are used to wind up the steel cable and can be locked. By winding up and releasing the steel cable 6, the height of the boom 8 is raised or lowered until the appropriate spraying height is reached, and the roller is locked to fix the position of the skin. In this embodiment, there are two supports 4, which are fixed at both ends of the main body 3 of the hanger and are used to support and fix the roller 5. There are two rollers 5, which are used to tighten and release the steel cable 6 and have a locking function. The steel cable 6 connects the boom 8, the movable part 7, the roller 5 and the main body 3 of the hanger and is used for raising and lowering the boom 8. There are four movable parts 7, which are fixed on the main body 3 of the hanger and contact the steel cable 6 to reduce the wear of the steel cable 6.
