Abstract

The invention discloses an adjusting platform. The adjusting platform comprises an upper platform and a lower platform which are arranged oppositely, at least three coarse-grade driving legs and at least three fine-grade driving legs, wherein each coarse-grade driving leg comprises a torque motor, a screw rod shaft which is fixedly connected with a rotor of the torque motor and a movable sleeve which is in thread connection with the screw rod shaft; each fine-grade driving leg comprises a linear motor, a connecting sleeve which is in relatively fixed with a stator and the linear motor and an elastic sheet which is arranged in the connecting sleeve; a first position of each elastic sheet is fixedly connected with a promoter of the corresponding linear motor; a second position of each elastic sheet is fixedly connected with the corresponding connecting sleeve. By adopting the structural design of the adjusting platform, the problems that the weight and size of the adjusting platform arerelatively large and the precision is low can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of optical component adjustment, and more specifically relates to an adjustment platform. Background technique [0002] With the continuous advancement of space technology, the requirements for the pointing accuracy of space optical loads are also getting higher and higher. The pointing technology of the optical load is the key technology to improve the range of observation and action and ensure good imaging quality. Its role includes two aspects: one is to increase the range of action of the optical load; the other is to stabilize the optical axis and compensate for factors such as satellite platform vibration. The optical axis pointing jitter improves the image quality. The ideal space optical load pointing technology needs to have the following characteristics: large adjustment range, high pointing accuracy, and good stability. In addition, in order to meet the needs of space applications, it is...
