Abstract

The invention discloses a three-support space mechanism with two same supports. The three-support space mechanism comprises a motion platform, a fixed platform and three support chains connecting the two platforms. The first support chain and the second support chain are identical in structure. Each of the first support chain and the second support chain comprises a universal joint pair, a rotation pair, a cylinder pair and connecting rods among the three pairs from the top to bottom. The third support chain comprises a universal pair, a rotation pair, a cylinder pair and connecting rods among the three pairs. The motion platform mechanism of a parallel robot mechanism is simple, kinematic model simpleness is achieved, kinematics calibration and related control are facilitated, and few mechanism joints and easiness in manufacturing are achieved at the same time.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a three-bracket spatial mechanism with the same double brackets. Background technique [0002] The parallel robot mechanism is a mechanism driven in parallel, which is very different from the transmission serial robot in terms of mechanism, kinematics, dynamics, etc. The parallel robot mechanism is widely used in motion simulators, parallel It is widely used in many fields such as machine tools, micro-manipulation robots and force sensors. [0003] However, the existing parallel robot mechanism still has some deficiencies such as poor manufacturability, complex structure, and high manufacturing cost. Contents of the invention [0004] The object of the present invention is to provide a three-bracket spatial mechanism with the same double brackets in view of the above-mentioned shortcomings and deficiencies of the prior art. [0005] To achieve the above object, the present invention ad...
