Rod Displacement Sensor Angle Measurement Fixture

Abstract

The invention provides a rod displacement sensor angular measurement clamp. A supporting plate is fixed to a frame body through screws, the frame body is composed of a support and a base plate, a round hole is formed in the middle of the supporting plate, three groove holes are evenly distributed in the periphery of the round hole, the positions of the groove holes are coordinated and consistent with three threaded holes in a rod displacement sensor, an index dial is fixedly connected with the upper portion of the supporting plate through bolts, a three-jaw gasket is arranged between the index dial and the supporting plate, three bolts of the three-jaw gasket fall into the three groove holes in the supporting plate respectively and are matched and connected with three long nuts, the rod displacement sensor is fixed to the supporting plate through the bolts and the long nuts, a circular boss on the upper end portion of the rod displacement sensor penetrates out of the middle round hole of the supporting plate and then is fixedly connected with a vernier through bolts, the vernier is used in cooperation with the index dial, and the position of the vernier and the position of the index dial are relatively fixed through a fastener. The rod displacement sensor angular measurement clamp solves the problem that the rotating angle of a rod displacement sensor pointer cannot be measured comprehensively and precisely.

Description

technical field [0001] The invention relates to a fixture for measuring the angle of a rod displacement sensor, which is used for precisely controlling the rotation angle of the pointer of the rod displacement sensor. Background technique [0002] Rod displacement sensor is a kind of angle measurement sensor commonly used in the technical field of aircraft, and the circular boss and pointer at the upper end of it play an indicating role. In the aircraft control system test, in order to ensure the accurate data required for the test, it is necessary to obtain the rotation angle of the pointer of the rod displacement sensor many times, and effectively record and analyze the test data corresponding to each angle, so as to obtain the corresponding value of the rotation angle of the sensor pointer. Test-related data, but on the rod displacement sensor, the angle dial is in units of 5°, which cannot comprehensively and accurately measure the rotation angle of the sensor. There are...

Problems solved by technology

In the aircraft control system test, in order to ensure the accurate data required for the test, it is necessary to obtain the rotation angle of the pointer of the rod displacement sensor many times, and effectively record and analyze the test data corresponding to each angle, so as to obtain the corresponding value of the rotation angle of the sensor pointer. Test-related data, but on the rod displacement sensor, the angle dial is in units of 5°, which cannot comprehensively and accurately measure the rotation angle of the sensor. There are limitations and large errors in the measurement results, which directly affect the comprehensiveness of the test conclusion and accuracy, resulting in the inability to comprehensively and accurately grasp the performance indicators of the aircraft, leaving hidden dangers to flight safety

In addition, due to the special structure of the rod displacement sensor, it cannot be measured with a traditional angle ruler
