Flexible assembling tooling

Abstract

The invention relates to a flexible assembling tooling. Six framework bases are divided into two groups, a framework upright column is arranged on the upper portion of each framework base, each row of framework upright columns is connected with a framework crossbeam, longitudinal guide rails I are arranged on upper surfaces of the framework crossbeams and connected mutually by upper movable crossbeams and horizontal linear guide rails II, a supporting framework is disposed at the inner side end of each group of framework bases, the supporting frameworks are connected with lower movable crossbeams by linear guide rails II, horizontal linear guide rails II are disposed on the lower movable crossbeams, and four modular positioning units are arranged on each of the horizontal linear guide rails and the horizontal linear guide rails II. The flexible assembling tooling can position main force bearing frames of afterbodies of various types of military planes by means of adjusting and reconstructing various modular positioning units, accordingly, the tooling for assembling the planes is used for various structural assembling modes, assembly and manufacture efficiency of the planes are greatly improved, manufacturing cost of the planes is saved, and simultaneously, the problem of large occupied area of an existing tooling is solved.

Description

technical field [0001] The invention relates to a flexible assembly tool, which is a tool device used for assembling the rear fuselage of a military aircraft. Background technique [0002] Aircraft assembly is a complicated process with relatively high technical requirements. Thousands of parts must be accurately positioned, connected and assembled, and the workload is very heavy. Traditional aircraft assembly adopts the form of rigid special tooling, and one tooling corresponds to the assembly of one structural part. Therefore, a large number of assembly toolings must be manufactured for each type of aircraft assembly. When the aircraft model changes, these special rigid tooling must be redesigned and manufactured, which not only prolongs the assembly and manufacturing cycle of the aircraft, but also increases the manufacturing cost, and the tooling storage occupies a large area. With the increase of various new models, tooling The problem of storage area is serious, and th...

Problems solved by technology

When the aircraft model changes, these special rigid tooling must be redesigned and manufactured, which not only prolongs the assembly and manufacturing cycle of the aircraft, but also increases the manufacturing cost, and the tooling storage occupies a large area. With the increase of various new models, tooling The problem of storage area is serious, and the above-mentioned disadvantages of traditional rigid tooling have seriously restricted the development of my country's aircraft manufacturing industry.
