Problems solved by technology
At present, in the field of physical and chemical mechanical testing, there is no standard measurement method for the measurement of the nut thrust of the engine guide vane assembly. When performing the measurement of the nut thrust of the guide vane assembly, the measurement process is not standardized, which affects the measurement results to a certain extent. reliability
At the same time, since the nut is at one end of the guide vane assembly, the guide vane assembly will be pried up during the process of applying pressure to the nut, resulting in non-vertical force on the nut, directly affecting the accuracy of thrust measurement, and even causing the Damaged nut

The invention discloses an engine guiding blade assembly screw cap thrust force measuring tool and a measuring method thereof, wherein the engine guiding blade assembly screw cap thrust force measuring tool comprises a bottom steel anvil, a positioning pressing sheet and a positioning ring; and the positioning pressing sheet and the positioning ring are mounted on the bottom steel anvil through fixing members. The measuring method of the invention comprises the following steps of 1) placing the measuring tool on a universal material measuring machine; 2) making engine guiding blade assembly screw cap thrust force measuring preparation, recording the number of an engine guiding blade assembly which requires screw cap thrust force measurement; 3) placing the engine guiding blade assembly to be measured in a fixed-position manner through the positioning pressing sheet and the positioning ring; 4) connecting a thrust force measuring screw with the engine guiding assembly screw cap through threaded connection, and ensuring no inclination of the thrust force measuring screw or disengagement of the thrust force measuring screw from the screw cap when the thrust force measuring screw is pressed in a measuring process; and 5) recording a measurement result, finishing measurement after a pressure which is bear by the engine guiding blade assembly screw cap meets a measurement technical requirement, recording data and removing the pressure.
Description
Technical field: [0001] The invention belongs to the technical field of thrust measurement of a nut of an engine guide vane assembly, and in particular relates to a tool and a method for measuring thrust of an engine guide vane assembly nut. Background technique: [0002] The technical specification of the guide vane assembly of a certain type of engine requires the thrust measurement of the nut. At present, in the field of physical and chemical mechanical testing, there is no standard measurement method for the measurement of the nut thrust of the engine guide vane assembly. When performing the measurement of the nut thrust of the guide vane assembly, the measurement process is not standardized, which affects the measurement results to a certain extent. reliability. At the same time, since the nut is at one end of the guide vane assembly, the guide vane assembly will be pried up during the process of applying pressure to the nut, resulting in non-vertical force on the nut,...
