Problems solved by technology
When the device is measuring, the rudder shaft transmits the rotation angle to the encoder through the rudder wing clamp body and the transmission mechanism. There are large errors in the entire transmission process, which reduces the measurement accuracy. At the same time, the structure of the device is complicated and the operation is inconvenient.

Embodiment Construction
[0025] The embodiment of a kind of rudder angle measuring device of the present invention: as Figure 1-3 As shown, it includes a square fixed base 1. The center of the fixed base 1 is provided with a circular positioning seat 4 for vertically positioning the measured piece. On the fixed base 1, four sliding guide rails are evenly distributed around the positioning seat 4 12. The four sliding guide rails 12 all extend radially along the circular positioning seat 4, and the four sliding guide rails 12 are all slidably matched with guide chute 22, the notch of the four guide chute 22 is downward and the groove bottom is upward, and the groove Encoder bases 2 are fixedly connected to the bottom. Of course, in other embodiments, the specific numbers of guide rails, guide chute and encoders can be adaptively selected and designed according to actual needs. The encoder seat 2 extends up and down, and its upper end is provided with a mounting hole 21 extending in the radial direction...

The invention discloses a rudder deflection angle measuring device and a calibration device for the measuring device. The measuring device includes a positioning mechanism and an encoder, the positioning mechanism includes a fixed base, and the encoder guides and moves and is assembled on the fixed base. The input shaft of the encoder extends along the direction of guiding movement, and the input end of the input shaft of the encoder is provided with an anti-rotation transmission block for anti-rotation plug-in cooperation with the rudder blade installation groove on the rudder shaft of the tested part. In front of the input end of the encoder input shaft, there is a mounting slot for fixing the tested part and making the anti-rotation transmission block be aligned and inserted into the rudder wing installation groove on the rudder shaft of the tested part during the movement stroke moving forward with the encoder. positioning device. The rudder deflection angle measuring device of the invention is easy to operate and has high measuring precision.
Description
technical field [0001] The invention relates to a rudder deflection angle measuring device and a calibrating device thereof. Background technique [0002] Existing aircraft with rudder wings, such as airplanes, missiles, etc., all realize the control of the flight state of the aircraft through the rudder surface. In order to ensure the stability of the aircraft during flight and to be able to adjust the flight angle of the aircraft at any time, the outer surface of the aircraft is generally uniformly distributed with multiple rudder wings, and a rudder shaft for controlling the rotation of the rudder wings is arranged inside the aircraft body. The rudder wing installation slot at the output end of the rudder shaft. When the aircraft is flying, the horizontal flight angle or the vertical flight angle of the aircraft is controlled by controlling and adjusting the deflection angle of the rudder wing, that is, the ascent, descent, and left-right deflection of the aircraft are c...
