Description
Technical field
The utility model relates to the fan rotor such as aircraft engine, civil aircraft assembling field, a kind of engine nut setting tool of special offer.
Background technology
When the fan rotor such as aircraft engine, civil aircraft assembles, by the restriction of spare part size so that assembling narrow space, spanner not easily launches, assembling difficulty.
Practical novel content
The purpose of this utility model is to provide a kind of engine nut setting tool, it is possible to launch in cylinder axle inside, it is achieved in the installation of narrow and small space inner nut.
The technical solution of the utility model is: a kind of engine nut setting tool, comprising: support 1, spanner head 2, pin I 3, torsion spring 4, traction cable 6; Described support 1 comprises steel pipe 1a and is located at pole I 1b and pole II 1c at steel pipe 1a two ends, described pole II 1c is connected by pin I 3 and torsion spring 4 with spanner head 2, described pole I 1b is provided with torque wrench open holes 1d, described spanner head 2 is provided with and torque wrench open holes 1d nut open holes 2a in the same horizontal line, described traction cable 6 one end is fixed on spanner head 2, and the other end is located on steel pipe 1a and is extend out to pole I 1b side.
Preferably, described pole I 1b and pole II 1c is provided with steel pipe 1a coupling end and is connected hanger, and the connection hanger of described pole I 1b and pole II 1c is located in steel pipe 1a by pin II 5 to connect and is welded into one-piece construction.
The utility model has following useful effect:
The utility model folding by spanner head, it is possible to realize the installation of nut in small space. Easy to operate, it may also be useful to safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that the utility model spanner head folds;
In figure: 1, support; 1a, steel pipe; 1b, pole I; 1c, pole II; 1d, torque wrench open holes; 2, spanner head; 2a, nut open holes; 3, pin I; 4, torsion spring; 5, pin II; 6, traction cable.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
The assembling position being assembled part in the present embodiment is positioned at first row's nut on the right side of engine fan rotor balance assembly, and limiter requires within the scope of 72N-78N, and instrument must enter in cavity from portlet, and nut installs position at �� 225mm circumferentially.
Use the utility model engine nut setting tool it to be assembled, as shown in Figure 1, comprising: support 1, spanner head 2, pin I 3, torsion spring 4, traction cable 6; Support 1 comprises steel pipe 1a and is located at pole I 1b and pole II 1c at steel pipe 1a two ends, pole I 1b and pole II 1c is provided with steel pipe 1a coupling end and is connected hanger, and the connection hanger of pole I 1b and pole II 1c is located in steel pipe 1a by pin II 5 to connect and is welded into one-piece construction; Pole II 1c is connected by pin I 3 and torsion spring 4 with spanner head 2, pole I 1b is provided with torque wrench open holes 1d, spanner head 2 is provided with and torque wrench open holes 1d nut open holes 2a in the same horizontal line, traction cable 6 one end is fixed on spanner head 2, and the other end is located on steel pipe 1a and is extend out to pole I 1b side.
During assembling, engine nut setting tool to be entered from right output port after folding up, as shown in Figure 2, instrument unclamps traction cable 6 after entering cavity, spanner head 2 is by torsion spring 4 elasticity, making spanner head 2 be bound to working position, spanner head 2 is processed with the nut open holes 2a coordinated with fastening nut, its central position is consistent with the torque wrench open holes 1d center on pole I 1b, power loss when avoiding exerting a force, prevents torque wrench reading value can not be subject to power actual value by actual response nut. Support 1 main body adopts steel pipe 1a structure, namely alleviates the weight of instrument, can not produce bending phenomenon when exerting a force again, ensure that the rigidity of instrument, installs through in-site modeling, and each item data all meets design requirements, reaches the object of expection.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this. All equivalences done according to the utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
