Title: Holder for machine tool
Inventor: TADANO TAKUSHI
IPC: B24B41/00
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To improve cylindricity, taper angle accuracy, and the like by providing a body part with a pair of actuators for displacing both sides of a fixed part so as to rotate the fixed part in a specified angle range. SOLUTION: An electricity-displacement converting element 15a (15B) on the voltage applied side applies load to a cutout part 13a (13b) of an angle adjusting base part 13 through a rigid ball 153 so as to displace the angle adjusting base part 13. As a result, the angle adjusting base part 13 is rotated in the direction of an arrow mark (a) around an elastic hinge part 12. In this state, suitable voltage is applied to the electricity-displacement converting element 15b (15a) on the side without voltaged being applied up to this time. Appropriate pre-load is therefore applied to both electricity-displacement converting elements 15a, 15b and the angle adjusting base part 13 so as to obtain the state of high rigidity and an excellent vibrating characteristic and an angl adjusted state.
