Abstract

The invention provides a two-shaft non-magnetic electric rotary table based on a piezoelectric ceramic motor. The two-shaft non-magnetic electric rotary table includes a horizontal rotary part and a pitching swing part, the horizontal rotary part comprises a base plate, three HR2 ceramic motors, a ceramic ring arranged between three HR2 ceramic motor output toggle fingers, a rotary ring adhered to the ceramic ring, and a grating disc connected to the rotary ring, one of the tree HR2 ceramic motors is provided with a rotary grating reading head support, the rotary grating reading head support is equipped with a rotary grating reading head, the grating disc is in fixed connection with an upper swaying body, a grating ruler is pasted to the upper end face of the grating disc, and the pitching swing part includes two upper swaying support blocks connected to the upper swaying body, two HR4 ceramic motors installed on the two upper swaying support blocks respectively, two ceramic chips arranged between two HR4 ceramic motor output toggle fingers, and an upper swing part bonded between the two ceramic chips. The two-shaft non-magnetic electric rotary table based on the piezoelectric ceramic motor provided by the invention has the advantages of no introduction of magnetic field, high precision, good dynamic performance, and good controllability, etc.

Description

technical field [0001] The invention relates to a two-axis non-magnetic electric turntable based on a piezoelectric ceramic motor, which belongs to the technical field of high-precision measuring instruments. Background technique [0002] With the rapid increase of industry, transportation, electric power and living facilities, people are in an increasingly complex electromagnetic environment, and the geomagnetic field has become more and more complicated in the local area. However, with the continuous advancement of science and technology, in the fields of precision measurement, aerospace, metrology and testing, the requirements for the external environmental magnetic field are getting higher and higher. For example, in the gyroscope used for navigation in aerospace and ships, the interference magnetic field seriously affects the navigation accuracy, and the interference magnetic field must be eliminated. In UAVs and inertial-guided medium- and long-range missiles, the per...
