The invention relates to a two-shaft four-frame photoelectric platform inner frame mechanism, comprising a motor support platform, four rotary voice coil motors disposed around the motor support platform, a load connecting arm, first, second and third connecting shafts, and first, second and third connecting arms; a load is fixed on the motor support platform and rigidly connected with the load connecting arm; the first connecting shaft is mounted in a shaft hole of the load connecting arm, the third connecting shaft is mounted in a shaft hole of the third connecting arm, and the first connecting shaft and the third connecting shaft are hinged to the second connecting shaft respectively through the first connecting arm and the second connecting arm; axes of the first, second and third connecting shafts intersect at a point. The invention provides a great reduction in frame dimensions and an improvement in load-carrying capacity of the platform, the small-size inner frame structure bears lower spatial constraints and has better adaptability, and the development and applicable range of a photoelectric platform is widened.
Description
technical field [0001] The invention belongs to the technical field of space optoelectronics, and in particular relates to a novel two-axis four-frame photoelectric platform inner frame mechanism. Background technique [0002] As a new type of real-time image detection equipment, the photoelectric platform is a system integrating light, mechanics and electricity. The optoelectronic platform with a stable structure of two axes and four frames is a very mature and conventional stabilization device. The outer frame is used for rough tracking, and the control accuracy of the platform is mainly realized by the inner frame system. For this structural form, due to the mechanical connection between the inner frame and the outer frame, the movement of the outer frame will be coupled to the inner frame, affecting the accuracy of the inner frame. Therefore, in order to realize the control of high-precision and high-stability optoelectronic platform, the optoelectronic platform needs a...
