Device for fine-adjustment of rotary chisels, for minimising the straight-line deviations of sliding carriages of rotary machines

摘要

The device comprises a frame (2) which is connected to a cylindrical shaft (1). The frame forms a support for a sliding carriage (3), and are both connected by leaf springs (10,11) which are deformable in the adjustment direction. Two counter-bearings (6,7) are formed on the frame. A piezo-actuator (5) is pre-stressed between the counter-bearings such that the operation of the piezo-actuator results in an adjusting movement of the sliding carriage.
