Manual double-shaft non-magnetic rotary table

Abstract

The invention discloses a manual double-shaft non-magnetic rotary table, which at least comprises a mechanical stage body, a mechanical base, an inner ring spindle unit, outer ring pitch axis units, inner-outer axis gears, a conductive slip ring, a shaft angle encoder and a console, wherein the mechanical base is provided with two outer ring pitch axis units, the inner ring spindle unit is arranged between the two pitch axis units, the two outer ring pitch axis units and the inner ring spindle unit are connected by the inner-outer axis gears, the conductive slip ring and the shaft angle encoder are arranged in the inner ring spindle unit, and the console mainly comprises a stabilized power supply unit, a multi-serial port information collection card, a one-machine dual-screen driver, an industrial personal computer and an auxiliary display screen. The manual double-shaft non-magnetic rotary table can serve as an inertial navigation system by taking a magnetic sensor as a main component to perform experiments such as test, calibration,loop simulation and the like on the ground, thus reducing the times of live shell flight and improving the success rate of live shell flight.

Description

technical field [0001] The invention relates to a precision non-magnetic two-axis rotating platform, which belongs to the field of inertial navigation. Background technique [0002] With the development of new technologies and the needs of the national defense industry, our country began to develop intelligent ammunition and low-cost smart-guided rockets during the Tenth Five-Year Period. The core components of these new weapon systems are inertial navigation systems. In order to achieve small size, Low cost, the magnetoresistive sensor is used as the angle measuring element (replacing the traditional vertical gyro), the sensitivity of the magnetoresistive sensor is generally 80nT, so the total magnetic index of the ground calibration and test equipment should not exceed 40nT. [0003] However, although the traditional turntable can achieve high precision, it cannot be non-magnetic, which makes the inertial navigation system unable to effectively test and calibrate, and seri...
