Detailed Description
With reference to fig. 1 and 2, a tool for measuring a deflection angle of a control surface includes a gauge body 10, a positioning component for positioning the gauge body, and a pointer 20 used in cooperation with the gauge body, wherein the gauge body is provided with a scale capable of determining a deflection angle of the pointer; the positioning measuring tool comprises a C-shaped part 11, a first positioning part 12 connected with one end of the C-shaped part, and a second positioning part 13 connected with the other end of the C-shaped part, wherein the positioning components are arranged on the first positioning part and the second positioning part; and a rotating approach measuring rod 30 is arranged on the C-shaped part, the rotating approach measuring rod is arranged opposite to the pointer, and the rotating approach measuring rod and the pointer point to the center of the C-shaped part.
The rudder 50 is installed on the measured substrate 51 through an articulated shaft, the measured substrate 51 is a simulation piece of a vertical stabilizer before the airplane is not put into operation, and the measured substrate is the actual vertical stabilizer after the airplane is put into operation.
In measurement, the rudder 50 is located at the center position of the C-shaped portion 11, and the first positioning portion 12 and the second positioning portion 13 are located on both sides of the base 51 to be measured. Before the gauge body 10 is fixed to the measured base body 51, the rotation approach measuring rod 30 is actuated so as to point at the hinge axis of the rudder and press it against the rudder, so that the measurement reference point of the gauge body 10 is determined. Thereafter, one end of the pointer 20 is mounted on the rudder surface, the pointer pointing to the hinge axis of the rudder. The first positioning portion 12 and the second positioning portion 13 are fixed to both sides of the base 51 to be measured by positioning members. The rotating proximity measurement stick 30 is then released and moved away from the rudder without contacting the rudder. The rudder 50 is rotated about the pivot axis relative to the measured base 51, whereupon the pointer 20 is rotated, and the rudder deflection angle is known by means of the scale on the gauge body 10. Wherein, as a preference, the rotating proximity measuring rod 30 is screwed on the C-shaped portion 11.
The measurer points the pivoting-in measuring rod 30 at the hinge axis of the rudder as a visual judgment, for example, by observing the hinge axis and the pivoting-in measuring rod from the side, i.e., by looking parallel to the hinge axis. The articulated shaft of pointer directional rudder adopts visual judgement equally, and this kind of judgement is inaccurate, has the error, but practical, high-efficient.
The first positioning portion 12 and the second positioning portion 13 are each a strip-shaped member, integrally formed with the C-shaped portion 11. For example, a single steel strip is bent. Therefore, the large measurement error caused by the displacement of the C-shaped part, the first positioning part and the second positioning part can be avoided. The gauge body 10 is formed integrally, and has a stable structure. The first positioning portion 12 and the second positioning portion 13 are parallel to two side surfaces of the measured substrate 51, respectively, and when the first positioning portion and the second positioning portion are fixed on the measured substrate, the parallel relationship between the first positioning portion 12 and the second positioning portion 13 and the two side surfaces of the measured substrate 51 can help a measurer accurately position the gauge main body 10, so as to improve the accuracy of measurement.
The positioning assembly includes a first set of threaded rods 41 that are threaded onto the first positioning portion 12 and a second set of threaded rods 42 that are threaded onto the second positioning portion 13. In the process of actuating the rotating approach measuring rod 30 to point to the hinge axis of the rudder and press the rotating approach measuring rod against the rudder, the measurer can actuate the first group of threaded rods 41 and the second group of threaded rods 42 simultaneously to gradually approach and press the first group of threaded rods 41 and the second group of threaded rods 42 against the two side surfaces of the measured substrate 51. After the mutual positions of the rotating approach measuring rod 30 and the rudder 50 are determined, the first set of threaded rods 41 and the second set of threaded rods 42 are pressed against the two side surfaces of the measured substrate 51, and the gauge body 10 is fixed on the measured substrate. The first positioning portion 12 and the second positioning portion 13 are parallel to both side surfaces of the measured substrate 51.
In order to ensure that the first positioning portion 12 and the second positioning portion 13 are respectively parallel to two side faces of the measured base body 51, a limiting member 43 is arranged on any one threaded rod in the positioning assembly, the distance from the limiting member to one end of the threaded rod where the limiting member is located is a certain value, the distance from the limiting member on all the threaded rods in the first set of threaded rods 41 to one end of the threaded rod where the limiting member is located is a certain value, one end of each threaded rod is pressed against the side face of the measured base body 51, and therefore the parallelism of the first positioning portion 12 and one side face of the measured base body can be ensured. Similarly, the limiting member on the second set of threaded rods 42 can ensure the parallelism between the second positioning portion 13 and the other side surface of the measured substrate. Alternatively, the position-limiting member 43 is a nut screwed on the threaded rod, and the position of the nut on the threaded rod can be adjusted to control the acting force between the threaded rod and the measured substrate, so that the device is suitable for measured substrates of different sizes.
The C-shaped portion 11 is provided with a strip-shaped groove 14 in which the pointer 20 is slidably fitted. The pointer is in sliding fit with the strip-shaped groove and does not limit the radial movement of the pointer along the C-shaped part.
One end of the pointer 20 is provided with a suction disc 21 which can be sucked on the rudder surface, so that the pointer and the rudder surface can be fixed simply and easily.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
