Abstract

The invention discloses a multi-freedom-degree parallel mechanism. The multi-freedom-degree parallel mechanism is composed of a motion platform, a fixed platform and three supporting chins connecting the two platforms. The motion platform of the parallel mechanism can achieve motion output of the three supporting chains, the mechanism is simple, machining and manufacturing are easy, a kinematics model is simple, so that kinematics calibration and control become easy. Meanwhile, the number of mechanism joints is small, and the structural rigidity is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a multi-freedom parallel mechanism. Background technique [0002] The parallel robot mechanism is connected by more than two branch chains between the fixed platform and the motion platform. Each branch chain is composed of a connecting rod and a motion pair. The motion platform has more than two degrees of freedom and is driven in parallel. , which is very different from the transmission series robot in terms of mechanism, kinematics, and dynamics. [0003] Parallel robot mechanisms are widely used in technical fields such as robots, CNC machine tools, sensors, micro-operations, manufacturing and processing, and researchers have also invented many parallel mechanisms. However, there are still some deficiencies in the existing parallel robot mechanism, such as poor manufacturability, complex structure, and high manufacturing cost. Contents of the invention [0004] The object of the pr...
