Non-glue joint sealing structure with power transmission function on liquid floated gyroscope shell and method

Abstract

The invention discloses a non-glue-joint sealing structure with a power transmission function on a liquid floating instrument shell. The non-glue-joint sealing structure comprises a conducting rod, an insulating glass body and a shell mounting hole. The conducting rod passes through the glass insulator with two ends exposed; two ends of the conducting rod are respectively welded with leads to ensure reliable power transmission; the insulating glass body wraps the middle section of the conducting rod, so that the middle section of the conducting rod is insulated from the outside; the insulating glass body is embedded into the mounting hole of the shell, and the glass body is tightly sealed with the mounting hole and the conducting rod through a glass sealing technology. In the sealing process, the shape, position and size of the conducting rod are ensured through a graphite positioning tool, and meanwhile, the flowing range of the insulating glass body in the heating and melting state in the sealing process is controlled. According to the invention, the problem of sealing reliability caused by glue joint failure in the conventional glue joint glass insulator structure of the liquid floating instrument is solved, the structural strength and high-temperature resistance are greatly improved, and the long-term reliability of the liquid floating instrument is improved.

Description

technical field [0001] The invention relates to a non-adhesive sealing structure, which belongs to the field of precision instruments. Background technique [0002] The working feature of the liquid floating gyroscope is to make the float assembly float in the floating oil in the shell, and the float is supported by the floating liquid to eliminate the frictional interference torque and improve the accuracy and stability of the instrument. The shell of the gyroscope is sealed to isolate the inside from the outside. At the same time, a power transmission device is installed on the shell as a structural carrier for the electrical connection between the inside and outside of the instrument. [0003] At present, liquid floating gyroscopes usually use glass insulators as power transmission devices, and the insulators are glued and assembled into the mounting holes of the shell, and the insulators are fixed and sealed by glueing. The sealing reliability of this part is affected b...
