The invention discloses an aircraft accessory ventilation metal hose installation angle adjusting device, and belongs to the technical field of aero-engine hose installation. The aircraft accessory ventilation metal hose installation angle adjusting device is used for adjusting an angle formed between a first section in the elbow section of an aircraft accessory ventilation metal hose and the endsurface of an engine accessory bracket when the elbow section of the aircraft accessory ventilation metal hose is mounted to a metal hard pipe. The aircraft accessory ventilation metal hose installation angle adjusting device comprises a clamping groove which comprises a groove matched with the first section of the elbow section and a first end surface perpendicular to the engine accessory bracket; a transferring frame is rotatably connected to the end of the clamping groove and is provided with a second end surface perpendicular to the first end surface; a connecting rod is rotatably connected to the other end of the transferring frame and is detachably connected to the engine accessory bracket, the second end surface of the transferring frame is provided with a strip-type structure, andthe walking direction of lines of the strip-type structure is arranged to be that when the lines are parallel to the first end surface, the groove of the transferring frame drives the deflected anglebetween the first section of the elbow section of the aircraft accessory ventilation metal hose and the end face of the engine accessory bracket to satisfy the design value. The angle adjusting devicehas high installation or detection precision and is convenient to operate and use.
Description
technical field [0001] The application belongs to the technical field of aero-engine hose installation, and in particular relates to a device for adjusting the installation angle of a fly-attached ventilation metal hose. Background technique [0002] Flying attached ventilation metal hose (also known as "metal hose") is used to transport the working medium of the aircraft accessory casing lubricating oil system, and compensate for the relative displacement and installation tolerance between the aircraft accessory casing and the engine. [0003] One end of the metal hose is fixedly connected to the flying attachment receiver, and the other end is connected to the metal hard pipe joint on the fixed hair attachment bracket. The space distance is long, and the suspended part of the hose is long. If the installation angle of the metal hose is not suitable, the prestress of the metal hose will increase. At the same time, the working environment of the metal hose is complex, and th...
