Abstract

The parallel mechanism disclosed by the present invention has two movement-rotation and two movement-helical movement modes, including a moving platform 10 and a fixed platform 11, and the moving platform 10 passes through the first branch chain, the second branch chain, the third branch chain and the Fixed platform 11 is connected. The three-degree-of-freedom parallel mechanism of the present invention solves the problem that the existing parallel mechanism has a single structure and cannot meet the working requirements under complicated circumstances.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a parallel mechanism with two movement-rotation and two movement-helical movement modes. Background technique [0002] The parallel robot mechanism is a closed-chain form with multiple degrees of freedom and multiple loops in space. Since the 1980s, parallel mechanisms have been widely used in virtual axis machine tools, micro-motion consoles, motion simulators and multi-dimensional force sensors because of their high rigidity, large bearing capacity, small cumulative error, good dynamic characteristics, and compact structure. Widely used in other industries. Parallel mechanisms have 2, 3, 4, 5 or 6 degrees of freedom. At present, the research on parallel mechanisms with 6 degrees of freedom is relatively comprehensive and in-depth, but the reduction of degrees of freedom in parallel mechanisms will make the mechanism structure simpler, manufacturing and control The ...
