摘要： 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.

摘要： The present disclosure discloses a five-degree-of-freedom hybrid robot with rotational supports. A first and a second fixed shaft seats are rotatably connected to a first and a second rotational support through a hinge, respectively. One end of a first length adjustment device runs through the first rotational support, and the other end is fixedly connected to a moving platform. One end of each of the second and third length adjustment devices runs through the first rotational support and is then connected to the moving platform, respectively. Middle portions of the first, second and third length adjustment devices are each hinged onto the first rotational support. One end of a fourth length adjustment device runs through the second rotational support and is connected to the moving platform. Middle portion of the fourth length adjustment device is hinged onto the second rotational support.
