A light and small pan-tilt frame torque motor and photoelectric code disc combined connection device

Abstract

The invention relates to a combined connection device for a frame torque motor and a photoelectric coded disc of a light and small holder, which comprises a photoelectric coded disc, a photoelectric coded disc support, four photoelectric coded disc fastening screws, a frame torque motor, a motor mounting base, a coupling, four motor stator fastening screws and two coupling fastening screws. When aspindle of the frame torque motor rotates, a photoelectric coded disc rotor can be enabled to keep synchronous high-precision rotation with the spindle of the frame torque motor due to a fixed connection effect of the combined connection device, thereby realizing real-time high-precision measurement for the displacement of the frame torque motor, providing real-time angular position measurement feedback for a frame angular position closed-loop control system, and achieving high-precision position tracking control for the light and small holder. The combined connection device can realize integrated connection of the torque motor and the photoelectric coded disc, and is compact in structure and simple and convenient to assemble and disassemble, thereby being applicable to a light and smallaviation remote sensing stable tracking system and other photoelectric equipment.

Description

technical field [0001] The invention belongs to the technical field of aviation remote sensing, and relates to a combined connection device of a light and small pan / tilt frame torque motor and a photoelectric code disc, which can be used for the integrated connection of a torque motor and a photoelectric code disc in a photoelectric stable tracking platform system such as a light and small pan / tilt. The rotor part of the photoelectric code disc can be kept in synchronous high-precision rotation with the main shaft of the frame torque motor, so as to realize the real-time high-precision measurement of the angular displacement of the frame torque motor. It is suitable for aerial remote sensing stable tracking systems and other optoelectronic equipment. Background technique [0002] The stable tracking platform is one of the key devices of aerial remote sensing. Its main function is to isolate the carrier disturbance, so that the optical axis (Line of Sight, LOS) can keep tracki...

AI Technical Summary

Problems solved by technology

The existing integral torque motor and photoelectric code disc combination device is mainly provided by the manufacturer, and the size, weight, torque, angle measurement accuracy, etc. are inconsistent with the design, and it is difficult to accurately select the model. Therefore, it is necessary to order and purchase the torque motor and photoelectric encoder separately. code wheel to meet design needs

However, there is no integrated connection device between the split torque motor and the photoelectric code disc, which brings inconvenience to use
