[0002] Aeroengines generally use servo motors to drive the throttle of the engine fuel regulator to control the amount of fuel intake. A multi-functional test bench such as image 3 As shown, the fuel regulator throttle of a certain type of aero-engine is installed in the upper middle position of the engine, while the fuel regulator throttle of another type of aero-engine is installed in the lower middle position of the engine. This test bench requires two The gantry of the servo motor, a set of general control cables, the gantry must be disassembled when installing and disassembling the engine, and the two aviation plugs on the servo motor must be disconnected when disassembling the gantry, and the electric throttle lever is easily triggered when disassembling the aviation plug. system error

The invention discloses an apparatus for controlling the angle of an aeroengine fuel-oil regulator by using a steel rope. A servo motor is installed on an engine test rig, a servo motor pedestal is provided with a steel rope support, an engine-end steel rope sheath is fixedly disposed on the steel rope support; and an engine portal frame is provided with another steel rope support and a steel rope sheath, and a steel rope passes through the steel rope sheath and connects a servo motor rocking arm and a fuel-oil regulator rocking arm. The technical advantages comprise that 1, operation is simple, labor intensity is reduced, and the thing only needing to do for mounting (or dismounting) the engine is to fixedly mount (or dismount) the end, close to the engine, of the steel rope on the support of the portal frame; and 2, production operation working time and workload are saved, and work efficiency and production efficiency are improved.
