Because there is error in the aspects such as processing, installation, there is the gap in aircraft rudder surface, and rudder face after wearing and tearing through long-time use, also can produce the gap in addition.When the rudder face gap exceeds limited range, affect safety thereby will affect aircraft handing characteristics, need accurately to measure.The principle in mechanical measurement rudder face gap is: to applying acting force on rudder face, record the deflection angle of rudder face under different power effects under pressurized state, draw the control surface deflection angle with the change curve of power, obtain by analysis the rudder face gap.At present, rudder face is applied acting force mainly rely on Weight gravity or motor-driven to provide, measure rudder face drift angle employing quadrant or graduated scale and directly measure, or adopt displacement transducer indirectly to measure.Counterweight can only provide certain several specific power, and it is also large to apply the required counterweight weight of larger acting force, operation inconvenience; Adopt motor drive mode, equipment is more expensive, and maintaining requires high.Directly measure rudder face drift angle operating efficiency with quadrant low, precision is not high, and graduated scale is high to installation requirement, and precision is also limited; Indirectly measuring rudder face drift angle principle with displacement transducer is to calculate the control surface deflection angle by measuring inclined to one side on rudder face or lower bias placement, but it converts displacement to clearance angle and spends journey and need to measure displacement point to rudder face rotating shaft distance, because the visual accessibility of rudder face rotating shaft is poor, can bring larger error in practical operation, and the displacement sensor apparatus expensive, economy is bad.To regulate through a large amount of before present measurement mechanism is measured, fit fully to guarantee loader and rudder face, measure different deflection angles, need displacement again fixing, and the rudder face fixture be larger, and inconvenience is installed.
Summary of the invention
The purpose of this utility model is: it is good that the purpose of the invention is to provide a kind of economy, can apply continuous action power and can measure quickly and accurately under the rudder face pressurized state or the device of the acting force under free state and control surface deflection angle rudder face.
the technical solution of the utility model is: the device of a kind of mechanical measurement rudder face loading force and deflection angle, comprise the first pulley 1, cable wire 2, power sensor 3, rudder face fixture 4, accent power screw mandrel 5, the second pulley 6, load bar 7, the 3rd pulley 8, jack 9, body frame pole 12, base 14 and cross bar 15, wherein, the load bar 7 of adjustable stroke is fixedly mounted on base 14, the middle part of its upper end and cross bar 15 is hinged, the first pulley 1 and the 3rd pulley 8 are equipped with respectively in the two ends of cross bar 15, the end that one end of the 3rd pulley 8 and body frame pole 12 are housed is hinged, the other end of body frame pole 12 is fixedly mounted on base 14, cable wire 2 one ends are successively by power sensor 3, accent power screw mandrel 5 is connected with rudder face fixture 4, cable wire 2 other ends are successively by after the first pulley 1 or the second pulley 6, are connected connection with jack by the 3rd pulley 8 again.
Described jack 9 is capstan winch.
Described body frame pole 12 also is equipped with fixed bar 13 with base 14.
Described load bar 7 is spirally connected by two external thread rods at internal thread cylinder and two ends and forms.
The present invention applies acting force by pulley blocks and cable wire array configuration to horizontal rudder face or vertical rudder face, with load bar or transfer the power screw mandrel to rudder face effect continuous force, angular transducer directly shows the control surface deflection angle, control surface deflection angle corresponding to device one-step installation, power and the deflection angle of measurement rudder face pressurized state or free state.
The utility model has the advantages that: the utility model is by pulley blocks and cable wire array configuration, and the direction of transfer pair rudder face acting force, both can survey horizontal rudder face and also can survey vertical rudder face easily.Charger is flexible the loading, and strong adaptability applies acting force to rudder face stable and continuous, and the angular transducer precision is high and easy to operate, and angle-data need not conversion and can directly read, rudder face fixture small, light.This device one-step installation just can the different control surface deflection angle of correspondence, not only can measure power, the angle curve of rudder face pressurized state, can also measure power, the angle curve of rudder face free state, i.e. the rudder face rotating torque.
