Description

[0002] The aviation electric mechanism is the control actuator on the aircraft, responsible for the operation and control of various functional software such as the power system, operating system, lubrication system, hydraulic system and air conditioning system on the aircraft. Therefore, the working stability of the aviation electric mechanism plays an important role in the flight safety of the aircraft. The electric mechanism detection equipment is used to test a certain type of electric mechanism and check the performance indicators of the electric mechanism. Its test process is to energize the electric mechanism to perform linear or rotational motion, and at the same time apply a stable force to the electric mechanism.

[0061] An aviation electric mechanism based on the same concept includes a device for applying a following force to the electric mechanism.

[0062] In some specific embodiments, a hanging rope 180 is further included, one end of which is fixed to the bottom of the aviation electric mechanism, and the other end away from the aviation electric mechanism is fixed with a hook 190 for hanging in the hanging hole 152 of the basic weight 150 .

[0063] Specific use process:

[0064] During use, the hook 190 at the bottom of the aviation electric mechanism is hung in the hanging hole 152 of the basic weight 150. The number of basic weights 150 and incremental weights required is determined according to the value of the follow-up force required during the movement of a certain model of the electric mechanism. If only one incremental weight and one basic weight 150 are required, only one incremental weight and one basic weight 150 need to be connected with the latch 153. Then, the rod of the jack is pressed to raise the loading platform 110 to a certain height, the loading rope of the equipment is hung in the hole above the basic weight 150, and the pressure relief valve on the jack is pressed to release the pressure, so that the loading platform 110 drops to the original position. In this way, the electric mechanism is subjected to a constant force, and the performance of the electric mechanism is tested.

[0065] If multiple weights are needed, it is necessary to connect the incremental weight to the basic weight 150 with the pin 153, and then take out another pin 153 to fix the incremental weight to the other incremental weights. The operation is convenient. By analogy, multiple incremental weights can be connected as needed.

[0066] According to the magnitude of the loading force, the electric mechanism is divided into the first level, the second level, ..., and the value of each incremental weight is obtained by subtracting the loading force of the previous level model from the required loading force of the electric mechanism of each model, and the weight increments are obtained in turn.

[0067] According to the size of the follow-up force required by the tested electric mechanism, several levels of incremental weights are selected and the corresponding latches 153 are installed, the pressure rod 170 of the jack is pressed to raise the loading platform 110 to a certain height, the loading rope of the device is hung into the hole above the basic weight 150, and the pressure relief valve on the jack is pressed to release the pressure, so that the loading platform 110 is lowered to the original position, so as to apply a constant force to the electric mechanism when it moves, so as to perform a performance test on the electric mechanism. The detection equipment of the present invention is simple to operate, occupies a small space, meets the existing test environment, and has low maintenance costs.
