Abstract

The invention relates to a four-degree-of-freedom posture leveling mechanism which comprises a movable platform, a fixed platform and four branch chains. The first branch chain comprises a ball pair, a first connecting rod, a first hook pair, a first driving block, a first moving pair and a first square column which are sequentially connected. Or the first branch chain comprises the ball pair, the first connecting rod, a first revolute pair, the first driving block, a cylinder pair and a cylinder which are sequentially connected. The second branch chain comprises a second hook pair, a second connecting rod, a second revolute pair, a second driving block, a second moving pair and a second square column which are sequentially connected. The first branch chain and the third branch chain are of the same structure and are arranged at opposite corners. The second branch chain and the fourth branch chain are of the same structure and are arranged at opposite corners. The four-degree-of-freedom posture leveling mechanism has the beneficial effects that the structure is simple, motion is simple comparatively, and control is concise comparatively; a novel machine type is provided for parallel motion equipment such as small-degree-of-freedom multi-dimensional vibration absorption, flight simulation, grabbing mechanisms, and the development and functionization of the parallel motion equipment are made possible.

Description

technical field [0001] The invention belongs to the technical field of parallel robots and relates to a four-degree-of-freedom attitude leveling mechanism. Background technique [0002] With the development of society, the process of trade globalization, and the urgent need for energy conservation and emission reduction, the ocean transportation industry is becoming more and more developed with its unique energy conservation. However, the seasickness of the crew and the low work efficiency. The protection of precision instruments is also urging the improvement of the ship's vibration reduction system. With the development of market demand, the traditional vibration reduction system has been widely used, but its existing vibration reduction effect can no longer meet the needs of the crew's life and work; here we propose a vibration reduction system that can be applied to ships parallel mechanism. [0003] The parallel mechanism is usually composed of a dynamic platform, a ...
