Description

Technical Field

[0001] The utility model belongs to the field of aviation, and in particular to the field of aviation equipment processing. Background Art

[0002] Battery pack PMA parts, the battery pack is installed in the emergency power supply assembly of Boeing aircraft to power the emergency lighting system in the cabin in the event of a main power failure. The battery pack is mainly composed of seven parts: shell, battery core, thermistor, connecting piece, wire, plug and fasteners. The shell includes an upper shell and a lower shell, and the battery core, thermistor, connecting piece, wire, plug, etc. are encapsulated in the cavity composed of the upper shell and the lower shell, and the edges of the upper shell and the lower shell are glued together.

[0003] During the assembly process, after the epoxy structural adhesive DP-420 in the upper shell is cured, apply a long strip of adhesive on the lower shell where it contacts the battery core, and apply epoxy structural adhesive DP-420 on the buckling positions around the upper shell and lower shell. Buckle the upper shell and lower shell together, clamp and fix them and wait for curing. In order to ensure the stability and consistency of the packaging curing process, it is necessary to use specific tooling to fix it. Utility Model Content

[0004] The utility model aims to provide a Boeing aircraft emergency lighting system power supply PMA component packaging tooling to solve the technical problem of power supply PMA component packaging consistency.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A Boeing aircraft emergency lighting system power supply PMA component packaging tool, characterized in that it includes a tool body, the tool body is rectangular, one side is provided with a staggered platform, the side opposite to the staggered platform is provided with a boss, the middle part of the staggered platform is provided with a positioning cavity for accommodating the power supply PMA component, the staggered platform is provided with mounting holes around, and the mounting holes are provided with quick clamps.

[0007] Furthermore, the positioning cavity is a rectangular cavity, and first positioning bosses are provided on both sides of the positioning cavity.

[0008] Furthermore, the first positioning boss extends from the bottom of the positioning cavity to the middle of the positioning cavity to form a second positioning boss.

[0009] Furthermore, an auxiliary positioning cavity is provided between the second positioning bosses.

[0010] Furthermore, the auxiliary positioning cavity is arranged between the second positioning bosses and is a rectangular depression arranged at the bottom of the positioning cavity.

[0011] Furthermore, the first positioning boss and the second positioning boss are both provided with chamfered corners.

[0012] The structure of the utility model has the following advantages:

[0013] 1. The first positioning boss and the second positioning boss facilitate positioning of the power supply PMA component;

[0014] 2. The auxiliary positioning cavity can be used to facilitate the adaptation of the surface structure of the power PMA component, and to retain the contact surface gap between the power PMA component and the tooling to a certain extent, so as to facilitate the removal of the power PMA component;

[0015] 3. By installing a quick clamp on the mounting hole, the local position can be adjusted according to the tolerance of each power PMA component, which is convenient for clamping and fixing, and consistent with the final curing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings, a Boeing aircraft emergency lighting system power supply PMA component packaging tooling.

[0021] like Figure 1 As shown, the Boeing aircraft emergency lighting system power PMA component packaging tool includes a tool body 1, which is rectangular, with a staggered platform 3 on one side, a boss 8 on the side opposite to the staggered platform 3, and a positioning cavity 4 for accommodating the power PMA component in the middle of the staggered platform 3, and the positioning cavity 4 is a rectangular cavity. Multiple groups of mounting holes 2 are distributed around the staggered platform 3, and the mounting holes 2 are connected to quick clamps by screws. After the power PMA component is placed in place, the quick clamps will quickly fix it.

[0022] Specifically, the quick-action toggle clamp is a mature prior art, and its specific structure is shown in the structure disclosed in patent document 202221969283.7.

[0023] Specifically, the offset 3 is prevented from being located in the same plane as the mounting hole 2, and during use, it is prevented from colliding with surrounding quick clamps when the power supply PMA component is placed.

[0024] Specifically, first positioning bosses 7 are provided on both sides of the positioning cavity 4. The first positioning boss 7 extends from the bottom of the positioning cavity 4 to the middle of the positioning cavity 4 to form a second positioning boss 5. The first positioning boss 7 and the second positioning boss 5 are both provided with rounded corners 9 to facilitate the placement of the power supply PMA component.

[0025] Specifically, an auxiliary positioning cavity 6 is provided between the second positioning bosses 5. The auxiliary positioning cavity 6 is provided between the second positioning bosses 5 and is a rectangular depression provided at the bottom of the positioning cavity 4, which retains the contact surface gap between the power supply PMA component and the tooling, and facilitates the removal of the power supply PMA component.
