Six-limb five-degree-of-freedom parallel machining robot

Abstract

The present invention discloses a six-limb five-degree-of-freedom parallel machining robot. The parallel machining robot includes a fixed base as basis of assembly, a limb group for pose adjustment, and a moving platform as output assembly. A motor spindle as an output unit is set in the moving platform. The limb group includes an unconstrained limb sub-group and a sixth limb movably connected with the fixed base. The parallel machining robot includes six limbs, the unconstrained branched strain sub-group is able to realize the installation of the five-degree-of-freedom parallel machining robot and is lower in cost. The sixth limb is a constrained limb. Under the constraint of the sixth limb, by controlling the extension and contraction of five unconstrained branched strains, the five-degree-of-freedom motion of the moving platform is achieved. The parallel machining robot includes six parallel limbs and has high rigidity. Through the sixth limb, the output assembly has large workspace. Therefore, the six-limb five-degree-of-freedom parallel machining robot provided by the present invention has advantages of high rigidity, good flexibility, large workspace and low cost.
