  "abstract": "Disclosed is a three-degree-of-freedom parallel mechanism, a parallel robot and a machine tool. The parallel mechanism includes a fixed frame and a moving platform, and the fixed frame includes a fixed seat and a cylindrical body fixedly connected to the fixed seat; three identical limbs are uniformly distributed in the cylindrical body in a circumferential direction, and each limb includes a prismatic joint A, a hinge A, a swing arm, a hinge B and a hinge C which are sequentially connected; an axis of the hinge A is perpendicular to an axis of movement of the prismatic joint A; an axis of the hinge B is perpendicular to, but does not intersect with the axis of the hinge A, which rotates around the axis of the hinge A; the hinge C has two rotational degrees of freedom.",
