Abstract
A positioning of a spindle with micrometric forwarding control and tilting of its rotation axis includes a spindle shaft rotatingly supported inside rotatable supports, wherein the rotatable supports include two spherical elements having housings which are eccentric with respect to the rotation axis that join the centers of the spheres, and wherein the two spherical elements are positioned in a cylindrical housing having at least two parts, and wherein two rotation elements are connected to the two spherical elements and cause their independent rotation.
Claims15
A positioning device of a spindle with micrometric forwarding control and tilting of a rotation axis of the spindle, the device comprising:
- a spindle shaft (11) rotatingly supported inside at least two rotatable supports,
- wherein said at least two rotatable supports comprise two spherical elements (13,14) provided with respective seat surfaces to receive said spindle, said spindle being eccentric with respect to an axis (99) passing through a center of said spherical elements, said two spherical elements (13,14) being positioned in a housing having at least two parts (17,17′;
- or 19,20);
- and
- two actuators (23,24) adapted to cause the two spherical elements (13,14) to rotate,
- wherein said two actuators actuate the two spherical elements independently from one another during rotation of the spindle shaft, and
- wherein said two actuators cause a controlled rotation of the two spherical elements (13, 14).
