Technical Field

The invention relates to the technical field of angular displacement sensor testing, in particular to a special measuring device for an angular displacement sensor.

Background

The angular displacement sensor is mounted on a certain airplane, has a large number of single machines, belongs to the matched products of hydraulic, control and power systems of the airplane, and is used for measuring the rotation angle of a movable part in the system and sending an electric signal corresponding to the angle to a flight parameter system and other airborne equipment. In the process of airplane overhaul and fault part repair, the maximum mechanical corner, the measurement precision, the working range and other performances of the product need to be detected. Because a special structural mode is adopted during product design, the rotation angle of the product is difficult to accurately measure during product repair, and repair adjustment and performance test are performed. The existing angular displacement sensor has no effective angle measuring method and special measuring tool, and cannot meet the requirements of product adjustment and performance test.

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.

As shown in fig. 1, a special measuring device for an angular displacement sensor comprises a base 1 and a support assembly 2 fixed on the base 1, wherein a graduated scale 6 for displaying a test angle of the angular displacement sensor, a butterfly nut 4 for fixing the angular displacement sensor on the support assembly 2, and a special pointer 5 for connecting the angular displacement sensor and the graduated scale 6 together are arranged on the support assembly 2, and the special pointer 5 is assembled on the graduated scale 6.

As a further improvement of the invention, the support combination 2 is also provided with a support arm 3, and the graduated scale 6 is fixed on the support arm 3.

As a further improvement of the invention, a product fixing frame 7 is arranged on the support combination 2, and the butterfly nut 4 is arranged on the product fixing frame 7.

As a further development of the invention, the position of the wing nut 4 on the product holder 7 is horizontally adjustable.

The testing process comprises the following steps:

during testing, the angular displacement sensor is connected with a special test bench for testing the angular displacement sensor through a cable.

Firstly, the butterfly nut 4 is matched with two holes on a bakelite seat of the angular displacement sensor, and the angular displacement sensor is fixed on a product fixing frame 7; then, inserting the special pointer 5 into the opening of the rotary cover of the angular displacement sensor, and fixing the special pointer by using a screw to ensure that the graduated scale 6 and the angular displacement sensor can synchronously rotate; then, the tip of a limiting slide block on the angular displacement sensor is adjusted to be aligned with the midpoint, and a special pointer 5 is aligned for 0 degree; then, a resistance ratio switch of the tester on the test board is opened, the special pointer 5 is rotated, a galvanometer on the test board is aligned to a zero point, an angle alpha is measured, and the output error of the angle alpha is calculated according to a formula eta which is (alpha-alpha standard)/60 degrees multiplied by 100 percent; then, the error of other check points on the angular displacement sensor is measured according to the method.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
