Universal adjuster for position and posture of spherical object

The invention belongs to the technical field of machining and agricultural product processing, and discloses a spherical object position and posture universal adjuster which comprises a bowl-shaped shell, a spindle friction wheel, a short hexagonal shaft, an upper rack, a straight spur gear, a long hexagonal shaft and a lower rack. The four spindle friction wheels and the spherical object are used for rolling friction, the axes of the two spindle friction wheels on each bowl-shaped shell are perpendicular to each other, and on the basis of the principle of motion synthesis and decomposition in physics, on the premise that the spherical object is clamped, the number of clamps does not need to be increased, and the clamping position does not need to be changed; the spherical object can accurately rotate by any angle along the x axis, the y axis and the z axis in the Cartesian coordinate system, and the effects of accurately positioning the spherical object and accurately adjusting the pose of the spherical obje
