Description
Technical Field
The application relates to the technical field of aircraft component assembly and manufacturing, in particular to an elastic ring flexible support adjusting structure and an adjusting method.
Background
When middle-sized parts of an airplane are assembled (such as structural assembly of an engine, an undercarriage and the like), two methods of hoisting and supporting are commonly used for installation, the hoisting is divided into a truss hoisting mode, an in-frame crane mode and the like, the supporting mainly adopts a precise positioning supporting mode and a flexible supporting mode, and the flexible supporting mode mainly adopts a mechanical lifting mode, a plane air suspension mode, a mechanical free sliding mode and the like for positioning installation. However, the existing supporting and mounting mode mainly adopts a mechanical structure in the Z direction, most of plane air suspension/mechanical free sliding has no resistance, the freedom is higher when the whole structure is mounted, and meanwhile, because the assembly precision of airplane components is higher, the collision can be generated to damage products due to slight poor control or errors. When the airplane components are assembled, a high-resolution large-range high-precision adjusting mechanism driven by small force is needed, and full-servo closed-loop feedback is also a good mode, but the mode is too complex and high in cost, the operation preparation time is long, and most of products are difficult to implement and apply due to the fact that products are easily damaged by human factors.
At present, the pneumatic auxiliary power balance structure with certain control force is less in bearing, other elastic structures are difficult to flexibly adjust particularly Z-direction structures due to stability, the existing domestic main adjusting structure is basically difficult to meet the requirement of high-precision flexible assembly of the existing airplane parts, and the development of a corresponding six-degree-of-freedom flexible assembly structure and a method with a force balance function and a larger adjusting range are urgently needed.
Disclosure of Invention
The utility model aims at providing an elasticity circle flexible support adjustment structure, this structure can be applicable to the accurate gentle and agreeable support dress of structural component especially aircraft medium-sized structural component.
In order to achieve the above purpose, the following technical scheme is adopted to realize the purpose:
the utility model provides an elastic ring flexible support adjustment structure, its structure includes upper mounting plate, lower platform, elastic ring subassembly, and the elastic ring subassembly is fixed between upper mounting plate, lower platform, treats that the support object places on the upper mounting plate surface, and lower platform bottom surface can cooperate with sliding structure or wheelset structure. The elastic ring components are uniformly distributed between the upper platform and the lower platform along the diagonal direction in a crossed manner. The elastic ring assembly consists of an elastic ring and connecting seats, the connecting seats are respectively fixed on the inner surfaces of the upper platform and the lower platform, and the elastic ring is fixed on the connecting seats. The elastic ring is of a spring steel cable structure. The connecting seat includes fixing base and grip block, and fixing base and grip block compress tightly the elastic ring through bolted connection and fix in dark semicircle pressure-sensitive groove and pressure-sensitive groove, and the elastic ring is local welding after the centre gripping is firm with fixing base, grip block extended position. The fixing seat is of a T-shaped seat structure, and the lug of the fixing seat is provided with an elastic ring deep semicircular pressing groove. The clamping block is provided with a pressing groove corresponding to the deep semicircular pressing groove.
The method has the advantages that the principle that the elastic structure of the elastic steel cable is combined in all directions is utilized, the small-range flexible posture adjustment of the assembly object component is realized, and the method has great technical advantages and applicability to the supporting and mounting of the aircraft landing gear and the engine.
The present application will be described in further detail with reference to the following drawings and examples.
