Abstract

The invention aims to provide a parallel metamorphism platform with variable degree of freedom. The parallel metamorphism platform consists of a frame, a workbench and three motion branch chains, wherein each motion branch chain is provided with two motors. The parallel metamorphism platform can be switched between three degrees of freedom and six degrees of freedom through a topological structure. Under the situation of three degrees of freedom, the workbench can be driven to move spatially in x, y and z directions through three horizontal motors. Under the situation of six degrees of freedom, the workbench can be driven to move and rotate spatially in x, y and z directions through horizontal and vertical motors. The state of the parallel platform can be switched freely according to different working conditions, thereby realizing needed motion locus through minimum driving. At present, most parallel mechanisms are of a single state, leading to redundancy of the degree of freedom. The parallel metamorphism platform is variable in the degree of freedom, has a very good market value, and the problem is well solved.

Description

technical field [0001] The invention relates to a motion platform. Background technique [0002] At present, parallel mechanisms are generally in a configuration with fixed degrees of freedom. However, there is a disadvantage of redundant degrees of freedom in many cases. The more degrees of freedom, the more complicated the control will be for the parallel mechanism. Therefore, the design of parallel mechanisms with variable configurations is of great significance. Contents of the invention [0003] The purpose of the present invention is to provide a parallel metamorphic platform with variable degrees of freedom that can realize conversion between three degrees of freedom and six degrees of freedom. [0004] The purpose of the present invention is achieved like this: [0005] A parallel metamorphic platform with variable degrees of freedom in the present invention is characterized in that it includes a frame, a motion branch chain, and a workbench; the frame includes...
