A device for assembling the main load-bearing frame of an engine thrust reverser

Abstract

The invention provides a main force-bearing frame assembling device for an engine anti-thrust device, and solves the problems that the accuracy of the assembly size and the position relationship of each component is difficult to ensure and the assembly difficulty is high in the assembly of a main force-bearing frame of the engine anti-thrust device in the prior art. The main force-bearing frame assembling device comprises a bracket, and a torque box component positioning mechanism, an outer culvert inner wall component positioning mechanism, an ear seat component positioning mechanism, an upper guiding-rail beam assembly positioning mechanism, a lower guiding-rail beam assembly positioning mechanism, a gas-leading hole assembly positioning mechanism, a checking template mechanism and a height adjusting mechanism are arranged on the bracket. The main force-bearing frame assembling device is used for the assembly of the main force-bearing frame of the engine anti-thrust device, the accuracy of the assembly size and the position relationship of each component is improved, and the assembly difficulty is low.

Description

technical field [0001] The invention relates to a device for assembling a sheet metal part of a space structure, in particular to a device for assembling a main load-bearing frame of an engine thrust reverser device. Background technique [0002] The main load-bearing frame of the engine thrust reverser is composed of an upper guide rail beam assembly, a lower guide rail beam assembly, an outer culvert inner wall assembly, a torque box assembly, an air guide hole assembly and an ear seat assembly. Each component is fastened with rivets and self-locking screws to form a whole, and there are size and position tolerance requirements between each component. How to ensure its assembly size and positional relationship in the assembly process has become a problem that must be solved. [0003] The applicant found at least the following technical problems in the prior art: in the prior art, the assembly of the main load-bearing frame of the engine thrust reverser is difficult to ens...
