The invention discloses a precise assembly device for a spherical sensor used for detecting a space electric field. The precise assembly device includes a support, the upper portion of the support is coaxially provided with a first fixing seat and a second fixing seat, a spherical sensor shell placement position is arranged between the first fixing seat and the second fixing seat, the first fixing seat and the second fixing seat are both coaxially provided with a sensor short-bar placement hole, the first fixing seat and the second fixing seat are both radially provided with a pluggable pin, the pluggable pin is arranged opposite to a taper hole position on a sensor short-bar, and the upper portion of the second fixing seat is provided with a torque spanner. The disclosed precise assembly device for the spherical sensor used for detecting the space electric field is scientific and reasonable in structure design, through a pressing force, in the axial direction of the short-bar, of the spherical sensor, the sphere diameter and the sphericity are effectively controlled, and accordingly the mechanical condition of the surface of the assembled spherical sensor is good in consistency.
Description
technical field [0001] The invention relates to the technical field of space environment detection, in particular to a precision assembly device for a space electric field detection spherical sensor. Background technique [0002] Space electric field detection is to use the surface of the sensor to sense the potential of the space plasma environment where it is located to achieve the purpose of electric field measurement. The electric field detector uses an active dual-probe electric field measurement method, and the consistency of the surface state of each sensor directly affects the accuracy of the electric field signal measurement in the low-density plasma space environment. The influence of the state consistency of each sensor after assembly: it reflects that when the electric field is measured in the actual space environment, it is the difference between the surface of the two sensors and the electric field of the plasma environment in the surrounding space. This differ...
