Problems solved by technology

According to the old method and the old technology to repair, the maintenance cost will gradually increase, and the maintenance quality is also declining. In addition, due to the large damage area of ​​some radomes, the maintenance becomes more difficult, and sometimes they are even scrapped because they cannot be repaired.

Embodiment Construction

[0048] see Figure 1 to Figure 5, is the maintenance tool embodiment of the civil aircraft A320 radome of the present invention, comprising: a mold made of fiberglass and thermosetting plastics, which is a spherical crown shell, and the shape of the inner surface of the shell matches the outer surface of the radome , that is, it can completely fit the outer surface of the radome. The outer surface of the shell is hooped with two ring-shaped reinforcing ribs with a diameter of 5 cm (not shown). The top of the shell is provided with a shaft head (or bearing), and the opening is a convex ring.

[0049] The thickness of the spherical crown shell mold is gradual: the thickness near the opening is 2cm, and it gradually thickens to 5cm towards the top. There are multiple positioning devices on the inner surface of the shell to accurately locate the radome, so that the radome and the mold can be accurately positioned. , closely attached and firmly positioned. There is a gentle edge ...

Abstract

The invention discloses a civil aircraft A320 radar cover maintenance tool which comprises a glass fiber and thermosetting plastic mold, a support and a swing frame. The glass fiber and thermosetting plastic mold is a ball coronary shell, the surface shape of the mold is consistent with the outer surface of a radar cover, the outer surface of the mold is hooped with annular reinforcing ribs, a spindle head is arranged at the top of the mold, and an opening is thickened into a convex ring. The support comprises a plane frame type base, four vertical support legs are arranged on the plane frame type base and symmetric about the front middle line and the rear middle line of the plane frame type base, each support leg is structurally in the shape of a fork with an upward opening, rollers are arranged at the bottom of the open fork, and clamping bolts are arranged on the upper portion of the open fork. The swing frame is a quadrilateral frame symmetric along the front middle line and the rear middle line, left and right opposite sides are arcs, the distance between the left and right arc opposite sides corresponds to that between the rollers on the forks of the bases. A bearing is arranged in the middle of a rear straight side, the shaft head of the mold is supported, a front straight side is provided with at least two rollers and supports the outer edge of a convex ring at the opening of the mold. The radar cover can be cured and formed once under the condition of large-area repair, cycle is shortened, quality is ensured, and cost is reduced.

Description

technical field [0001] The invention relates to a maintenance tool for a civil aircraft A320 radome. The invention also relates to the maintenance process of civil aircraft A320 radome by using the tooling. Background technique [0002] Today, China Southern Airlines alone has 240 A320 series aircraft, and the maintenance market for radomes is huge. And with the passage of time, the damage degree of the A320 radome is gradually increasing, and the maintenance level is gradually deepening. According to relevant statistical data, from 2010 to 2013, the number of radome repairs sent by China Southern Airlines has increased year by year, from 9 repairs per year to 19 repairs per year; at the same time, the repair area is getting bigger and bigger, and the repair cycle is getting longer and longer , from an average of 17 days to complete, a sharp rise to an average of 47 days to complete. According to the old method and the old technology to repair, the maintenance cost will g...
