Astatic balance debugging method for inner ring assembly of frame type angle measuring device

Abstract

The seeker position calibration system is a frame type angle measuring device, and the static balance of its inner ring components directly determines the stability of the product performance. This paper makes full use of the advantages of the pressure sensor, carries out analog-to-digital conversion and data acquisition through HX711, displays the collected results on the LCD screen, and analyzes and processes the data. A device that automatically measures the static balance of the frame in the seeker position calibration system is designed. The device uses four embedded pressure sensors to realize that if the product is unbalanced when placing the inner frame of the product on the balancing tool rest, one end of the inner frame will press on the balancing device due to gravity. By displaying the size of the pressure value and fitting with the least square method, the relationship between the pressure value and the thickness of the increased or decreased shims of the product is realized, and the universality of the relationship is verified. One calculation can realize the accurate adjustment of the static balance of the frame in the seeker position calibration system.
