The dummy device simulates the state of assembling the engine, the weight and the gravity center of the dummy device are consistent with those of the engine, the two sides of the dummy device are provided with joints connected with the engine body, and the joints are consistent with the joints connected with the engine body on the engine; it is installed on the aircraft before the assembly of the structural element where the point of intersection of deformations due to the fitting of the engine is located. The utility model has the advantages of as follows: the installation state of the engine is simulated, the problem of incongruity of parts caused by deformation of certain intersection points generated after the engine is installed can be solved, and the manufacturing accuracy of the airplane is improved.
Description
Technical Field
The utility model relates to a device that structure was coordinated is carried out to simulation aircraft installation engine state is applicable to the condition that aircraft structure leads to relevant group's part to coordinate the difficulty because of warping around the engine mounting in the aircraft manufacturing process.
Background
The aircraft engine is relatively heavy, and even if the aircraft has good rigidity and enough strength, the aircraft framework can be slightly deformed after the engine is installed. In the manufacturing process of an airplane, an engine is installed after a structural part and most system parts are assembled, so that after the engine is installed, the intersection point of the previously installed structural part generates micro deformation, and even if the deformation is small, the part with high intersection point coordination requirement is influenced, for example, a bolt lock of an engine door of a certain type of airplane has the phenomenon that the bolt cannot enter a bolt hole after the engine is installed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a false body device of simulation aircraft dress engine state for in the aircraft manufacturing process, solve because some nodical deformation that the installation engine leads to and the inconsistent problem of spare part that produces.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the dummy device simulates the state of assembling the engine, the weight and the gravity center of the dummy device are consistent with those of the engine, the two sides of the dummy device are provided with joints connected with the engine body, and the joints are consistent with the joints connected with the engine body on the engine; it is installed on the aircraft before the assembly of the structural element where the point of intersection of deformations due to the fitting of the engine is located.
Preferably, the dummy device has a volume smaller than the volume of the engine.
Preferably, the dummy device is made of steel and filled with lead.
Compared with the prior art, the utility model has the advantages of as follows: the installation state of the engine is simulated, the problem of incongruity of parts caused by deformation of certain intersection points generated after the engine is installed can be solved, and the manufacturing accuracy of the airplane is improved.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, 1, an engine dummy part; 2. a center of gravity; 3. and (4) a joint.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawing 1: a dummy device for simulating the state of assembling an engine is made of two materials of high density and high weight, wherein the steel material is filled with lead in the middle, the volume of the dummy device is far smaller than that of an engine dummy 1 of the engine, the weight and the gravity center 2 of the dummy device are both consistent with that of the engine through calculation, but the dummy device is far smaller than that of the engine, and joints 3 connected with a machine body are arranged on two sides and are consistent with those of the engine and the machine body. The engine dummy part is installed on an airplane before the structural part where the intersection point which is deformed due to the assembly of the engine is installed is assembled, so that the installation state of the engine is simulated, the positioning accuracy of parts of which the intersection point can be slightly changed after the engine is installed is ensured, and the engine dummy part is detached after the parts are assembled.
When the state of an engine needs to be simulated and installed, the needed engine dummy piece is manufactured according to the installation form of the aircraft engine, for example, a certain aircraft engine dummy piece is shown in figure 1, the state of the engine installed on the aircraft can be simulated by installing the dummy piece on the aircraft according to a connector, and the dummy piece can be detached when a real engine needs to be installed or the state is not needed.
The above embodiments are merely further descriptions of the present invention, and do not constitute limitations of the present invention. It should be understood by those skilled in the art that in the same or similar technical field as the present invention, there is also some problem of incongruity before and after installation of other parts caused by deformation, and the present invention can be applied.
