Six-degree-of-freedom attitude adjustment docking platform

Abstract

The invention relates to a six-degree-of-freedom attitude adjustment docking platform. The six-degree-of-freedom attitude adjustment docking platform mainly comprises a mobile base, a bottom layer three-degree-of-freedom motion platform and a top layer three-degree-of-freedom motion platform. According to the six-degree-of-freedom attitude adjustment docking platform, driving motors of the bottomlayer motion platform are symmetrically arranged, so that the driving motors are uniformly distributed in the plane of the platform, the overall quality of the platform is uniformly distributed, and the platform has better balance, so that the dynamic performance is improved. Crisscross linear sliding ways are adopted in the platform so as to be on the same layer with a supporting frame A, and circular sliding ways are adopted so as to be on the same layer as a supporting frame B. The same layer distribution is favorable for height dimension compression and height increase caused by series connection of structures is reduced. The position and posture adjustment of the bottom layer motion platform is realized by utilizing the differential principle of four driving electric cylinders, so that the superposition of space layers caused by the one-to-one corresponding distribution of drivers and driving objects in a traditional mode is avoided, the traditional driving arrangement space is optimized, and the platform is enabled to be compact in height direction.

Description

Technical field [0001] The invention relates to the field of six-degree-of-freedom attitude adjustment platforms, in particular to a six-degree-of-freedom automatic attitude adjustment tool used for installation and docking of large aerospace equipment. Background technique [0002] With the increasing development of the aerospace industry, the demand for installation and docking of large-scale cabin equipment continues to increase, and the requirements for the installation and docking process are becoming more and more stringent, and the traditional installation and docking device has a huge structure, which is not conducive to the reasonable arrangement of working space and severely restricts large-scale aerospace The efficiency of equipment installation and docking operations is improved. At present, most of the six-axis attitude adjustment platform mechanical system consists of a base and multiple sub-platforms. It mainly provides installation reference for the load and reali...

Problems solved by technology

However, the general problem of this type of platform is that the structure is not compact enough, and the dimension space in the height direction is difficult to compress. Each shafting must be attached with a set of drive units, and the arrangement of these drive structures is not conducive to compressing the height space, which will inevitably increase The space size and quality of the shafting hinder the improvement of the performance of the platform
