An assembly and inspection device for a transition beam

Abstract

A transition beam assembly and inspection device comprises a main body assembly component, wherein the main body assembly component comprises bases, an upper front positioning pin, an upper front inspection pin, vertical plates, covering positioning inspection blocks, an upper rear positioning pin, an upper rear inspection pin, a lower front positioning pin, a lower front inspection pin, bottom plates, horizontal positioning plates, an upper positioning plate, front positioning blocks, upper horizontal plates, rear positioning blocks, a lower rear positioning pin, a lower rear inspection pin and lower connecting plates, wherein the covering positioning inspection blocks are arranged on the lower connecting plates and the bottom plates; the lower front positioning pin and the lower rear positioning pin are used for positioning a front suspension cross beam and a rear suspension cross beam on the front positioning blocks and the rear positioning blocks; the upper front positioning pin and the upper rear positioning pin are used for positioning a front vertical shaft and a rear vertical shaft on the upper positioning plate; the upper front inspection pin is arranged behind the upper front positioning pin; the lower front inspection pin is arranged behind the lower front positioning pin; the lower rear inspection pin is arranged behind the lower rear positioning pin. The device has the advantages that the structure is simple, the operation is convenient, and the transition beam assembly and inspection problems are well solved. The transition beam assembly and inspection device is suitable for assembly and inspection of various transition beams.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an assembly and inspection device for a transition beam. Background technique [0002] The transition beam is a part of the external hanging system of the aircraft. It belongs to a typical frame-skin structure. It mainly consists of two front and rear beam components to form a frame, and then riveting various skins on its surface, making it a simple structure and light weight. , Suspension transfer beam with good strength. For the assembly and inspection of this structural product, the following methods are mainly used at present: the front and rear beams are simply fixed, and then the skins are riveted on the beams according to the assembly relationship. This kind method has following problem: 1, must repeatedly setback repair during skin assembly, expends a large amount of man-hours. 2. The skin may be deformed after assembly, causing the entire product to be...

AI Technical Summary

Problems solved by technology

This method has the following problems: 1. It must be repeatedly repaired during skin assembly, which consumes a lot of man-hours

2. The skin may be deformed after assembly, causing the entire product to be distorted and deformed, which does not meet the assembly requirements

3. The positioning of the front and rear beam components is inaccurate, making it difficult to ensure the accuracy of the upper and lower interface dimensions, heading and pitch angles of the product
