Problems solved by technology

Since this method needs to install two 45° reflectors on the top and outside of the precision centrifuge spindle, and the light of the dual-axis dynamic photocollimator is also transmitted through the outside, it cannot be used in many space-effective conditions and is easily affected by the outside world. interference; secondly, it is difficult to adjust the coincidence degree between the center of the optical adjustment path and the shaft center of the precision centrifuge, and the efficiency is low; moreover, the entire system required by this detection method is complex and costly

Abstract

The invention discloses a device for detecting a static azimuth misalignment angle of a precise centrifuge and a method thereof. The device comprises the components of a precise mounting base for mounting a detected member, an air floatation square rail with an air floatation sliding sleeve, a gauge block, a magnetic meter rack and a dial gauge. One end surface of the gauge block closely abuts against the measuring surface of the precise mounting base. The air floatation square rail simultaneously abuts against the other end surface of the gauge block and the external surface of a rotary main shaft. The dial gauge is mounted on the magnetic meter rack. The magnetic meter rack is mounted on the air floatation sliding sleeve. In detection, the air floatation sliding sleeve slides from a certain point at one end of the a measuring surface of the precise mounting base to another certain point at the other end along with the magnetic meter rack and the dial gauge. The static azimuth misalignment angle of the precise centrifuge can be obtained dividing an indication difference of the dial gauge between the two position points by a distance between the two points and computing an antitangent value of an obtained value. The device and the method have advantages of settling a problem of high difficulty in detecting the static azimuth misalignment angle on condition of limited space, simplifying a system, improving an interference resistance, realizing lower cost, improving detecting efficiency and reducing detecting cost.

Description

technical field [0001] The invention relates to a static azimuth misalignment angle detection device and method for a precision centrifuge, which belongs to the technical field of inertial device testing equipment and can be applied to the inspection, verification and test of a precision centrifuge. Background technique [0002] The existing method for measuring the static azimuth misalignment angle of a precision centrifuge is to use a dual-axis dynamic photoelectric collimator method: the accelerometer is mounted on a precision mount, a 45° moving mirror is installed on the axis of the main shaft, and a mirror is placed on the top of the main shaft. Install a 45° static mirror in the space, and finally install a dual-axis dynamic photoelectric collimator in the top space of the precision centrifuge, adjust the optical path so that the center of the optical path coincides with the axis of the precision centrifuge spindle and merge on the reflective surface of the precision m...
