Description
Technical Field
The application relates to the technical field of steering engine detection, in particular to a steering engine rudder shaft position detection device.
Background
The steering engine of the aircraft is a key actuating mechanism for controlling the steering surface (control surface) of the aircraft to rotate in an autopilot so as to realize posture transformation motions of pitching, yawing, rolling and the like of the posture of the aircraft. The steering engine is a high-precision servo mechanism and mainly comprises a steering body, a steering surface, a driving part, a transmission part, a controller and a sensor. The working principle is that the controller sends out a signal to start the steering engine driving part, the driving part transmits power to the control surface through the transmission part to enable the control surface to rotate, meanwhile, the sensor sends back a signal to the controller to judge whether the control surface reaches a designated position, and the controller further adjusts the position of the control surface based on the signal transmitted back by the sensor, so that the attitude transformation of the aircraft can be realized. The accuracy and the dynamic response quality of the flight track of the aircraft are directly determined by the performance of the steering engine, the transmission part of the steering engine is connected with one end of the control surface through the steering shaft interface groove, and the error between the instruction angle of the controller and the actual deflection angle of the control surface cannot be too large. Before delivery, the steering engine needs to detect whether a steering shaft interface groove of the steering engine accords with technical indexes.
For the detection of the technical indexes of the rudder shaft interface groove, a dial or an angle meter is often adopted for detection. The actual rotation angle of the rudder shaft interface is detected by the detection equipment, so that the problems of inconvenient operation, extremely low detection efficiency, extremely high detection cost and the like exist. In the steering engine, if the position accuracy of the rudder shaft interface groove is detected by using the dial, the dial accuracy is difficult to ensure and the data is difficult to read. If the angle measuring instrument is adopted for detection (namely, the angle of rotation of the rudder shaft interface is transmitted to the angle measuring instrument by the square shaft in clearance fit with the groove), the angle generated by the fit clearance between the interface groove and the transmission shaft is larger because the length of the rudder shaft interface groove is shorter, so that the angle detection error is unstable, and even exceeds the angle error.
