Problems solved by technology

[0008] One of the ways to solve the winding problem in the prior art is to add a disc-type conductive slip ring to the pitch axis assembly. However, the radial size of the disc-type conductive slip ring is large, which increases the total mass, overall size and motion envelope of the mechanism. Increased the structural complexity of the pitch axis assembly, especially in the aerospace field, the existence of conductive rings is not conducive to the reliability of the equipment in terms of mechanics and space environment adaptation

Abstract

The invention discloses a novel periscopic pointing mechanism, which comprises an azimuth shell, an azimuth axis driving assembly and a pitch axis driving assembly, wherein an azimuth axis driving motor is assembled and fixed on an azimuth axis driving motor mounting flat plate, and drives an azimuth axis to rotate through an azimuth axis transmission mechanism so as to drive an azimuth reflex reflector assembly above to move, and a pitch axis driving motor is assembled and fixed on a pitch axis driving motor mounting flat plate, and drives a pitch axis to rotate through a pitch axis transmission mechanism so as to drive a pitch reflex reflector assembly above to move. According to the invention, the pitch axis driving motor of the pointing mechanism is integrated on the side surface of the azimuth shell, and the pitch axis is driven to move through the pitch axis transmission assembly, so that the problem of winding does not exist, the influence of cable winding and dragging on servo performance does not exist, the movement stability of the mechanism is improved, installation of a conductive slip ring is avoided, the mechanism structure is simple and reliable, the load rotational inertia of the azimuth axis and the pitch axis is reduced, and the dynamic performance of the mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of optoelectronic engineering, in particular to a novel periscope pointing mechanism. Background technique [0002] In the field of optoelectronic engineering, the PAT (Pointing, Acquisition, Tracking) system is an important part of many types of precision instruments such as optoelectronic tracking, laser communication, photoelectric scanning detection, deep space detection, etc., and can realize pointing and aiming at any azimuth in space Or tracking and other functions. [0003] In the PAT system, CPA (Coarse Acquisition and Acquisition Mechanism) is one of the key mechanisms to achieve capture and tracking; common two-axis CPA forms include: rotating double prism type, pendulum mirror type, periscope type and latitude and longitude ceremony (X-Y frame type and Horizontal type - T type, L type, U type). Compared with other CPA structure forms, the outstanding advantages of the periscope tracking mechani...
