Description

Technical Field

[0001] The utility model relates to the technical field of aviation wire harness assembly auxiliary equipment, in particular to an airborne wire harness flexible auxiliary assembly device. Background Art

[0002] Aircraft wiring harnesses are used for electrical signal transmission within aircraft and are widely used in the avionics field. To accommodate the aircraft's aerodynamic shape and internal structural space, the layout of the wiring harness within the aircraft is often complex, with poorly regulated installation patterns and frequent large bends and height differences. Furthermore, aircraft are subject to harsh operating environments, particularly some aircraft models, which are subject to high levels of vibration and acceleration overload. Under these conditions, the wires within the harness are often pulled and tugged, making them prone to breakage and other faults. Lengthening the harness arbitrarily increases weight, hindering aircraft weight reduction.

[0003] The traditional method of wiring airborne wire harnesses is to use a 1:1 drawing (or a customized wiring board) to route the wires on a plane. This method can ensure the planar shape characteristics of the wire harness from a 2D perspective, but it is far from adapting to the spatial shape characteristics of the wire harness. In addition, the wiring board must be customized according to the wire harness and has no universality. Utility Model Content

[0004] The utility model aims to provide an airborne wire harness flexible auxiliary assembly device which can be widely used in different aircrafts and different space shapes.

[0005] The utility model is realized through the following technical scheme: a flexible auxiliary assembly device for an airborne wiring harness, comprising a grid-shaped positioning frame and a number of positioning rods, a positioning plate being installed on each node of the grid on the positioning frame, and the positioning rod being able to be installed on the positioning plate, thereby realizing the fixed installation of the mounted airborne wiring harness.

[0006] This technical solution works by defining each grid intersection on the positioning disk as a two-dimensional coordinate for the wiring harness on a plane, providing positioning and limiting for the locating rods. Each locating rod can be moved to any grid intersection on the positioning disk. Once the locating rod has reached the corresponding grid intersection on the positioning disk, the rod's height is adjusted to determine the relative heights of key nodes in the wiring harness. Once multiple locating rods have defined key points in the wiring harness, 3D routing and production can begin.

[0007] In order to better realize the present invention, the positioning rod further includes a main rod body, a lifting rod that can slide up and down and rotate on the main rod body is nested on the upper part of the main rod body, a rotating rod is hinged on the top of the lifting rod, and a spring clip for mounting an onboard wiring harness is installed at the free end of the rotating rod.

[0008] In order to better realize the present utility model, further, the upper outer wall of the main rod body is provided with an external thread, a spiral sleeve is nested on the main rod body, the inside of the threaded sleeve is provided with an internal thread matching the external thread on the upper part of the main rod body, and the top of the main rod body is also provided with a notch, and the threaded sleeve is fixed to the lifting rod and the main rod body by being threadedly connected to the upper part of the main rod body.

[0009] In order to better realize the present utility model, further, a positioning seat is fixedly provided on the lower part of the main rod body.

[0010] In order to better realize the present utility model, further, a mounting handle is provided in the middle of the main rod body.

[0011] In order to better implement the present invention, further, the rotating rod is composed of at least two thin rods with hinged ends, and a spring clip is fixedly installed on the end of the thin rod with a free end.

[0012] In order to better implement the present invention, further, the grid shape of the positioning frame is rectangular.

[0013] In order to better realize the present invention, further, a plurality of support columns are provided at the lower portion of the positioning frame.

A positioning plate 2 is installed on each grid node on the positioning frame 1. The positioning rod 3 can be installed on the positioning plate 2 to achieve fixed installation of the mounted aircraft wiring harness 4.

[0029] The specific usage process is to determine the important grid points required to form the airborne wiring harness 4 according to the grid intersections on the positioning frame 1, and then install the positioning rods 3 on the positioning disk 2 at the important grid points, and then perform three-dimensional wiring and production. During this period, the height and angle can be fine-tuned through the positioning rods 3.

[0030] Example 2:

[0031] Based on the above embodiment, this embodiment further defines the specific structure of the positioning rod 3, such as Figure 2 , Figure 3 As shown, the positioning rod 3 includes a main rod body 31, and a lifting rod 32 that can slide up and down and rotate on the main rod body 31 is embedded in the upper part of the main rod body 31. The top of the lifting rod 32 is hinged with a rotating rod 33, and the free end of the rotating rod 33 is installed with a spring clip 34 for mounting the airborne wiring harness 4. The positioning rod 3 is moved to the corresponding plane coordinate point of the positioning disk 2 for constraint and fixation. After determining the approximate plane point of the node, the various parts on the positioning frame 2 can be adjusted for precise positioning. The lifting rod 32 can be raised and lowered, the rotating rod 33 can be rotated, and the spring clip 34 fixes the airborne wiring harness 4, thereby completing the fine-tuning of the spatial coordinate point. Multiple sections of the airborne wiring harness 4 are continuously fixed on the spring clip 34, and finally form a finished wiring harness product. The other parts of this embodiment are the same as the above embodiment and will not be repeated here.

[0032] Example 3:

[0033] Based on the above embodiment, this embodiment further defines the specific structure of the positioning rod 3, such as Figure 2 , Figure 3As shown, the upper outer wall of the main rod body 31 is provided with an external thread, and a spiral sleeve 35 is embedded in the main rod body 31. The interior of the threaded sleeve 35 is provided with an internal thread that matches the external thread of the upper portion of the main rod body 31. The top of the main rod body 31 is also provided with a notch. The threaded sleeve 35 is threadedly connected to the upper portion of the main rod body 31 to secure the lifting rod 32 to the main rod body 31. The lifting rod 32 is directly inserted into the middle cavity of the main rod body 31, and a small gap exists between the outer wall of the lifting rod 32 and the inner wall of the hollow cavity of the main rod body 31, so that the lifting rod 32 can be freely adjusted in height. The spiral sleeve 35 is threadedly connected to the upper end of the main rod body 31. Once the lifting rod 32 is adjusted to the appropriate height, the spiral sleeve 35 is tightened, which compresses the upper end of the main rod body 31, reducing the inner diameter of the closing and clamping the lifting rod 32, thereby locking the lifting rod 32 and achieving the purpose of limiting the position.

[0040] Example 7:

[0041] Based on the above embodiment, this embodiment further defines the specific structure of the positioning frame 1, such as Figure 1 As shown, the grid shape of the positioning frame 1 is rectangular.
