Linear drive e.g. impact wrench for e.g. connecting rod of machine construction, has pre-stressed compression spring pressing against clamping unit to effect linear forward motion of structures of rod against impact direction of impact unit

摘要

The drive has a clamping unit (2) which is provided on a connecting rod and is shifted by an electromagnetically driven impact unit (3a). A pressing unit is provided on an opposite side of the clamping unit. The pressing unit has a pre-stressed compression spring (5) which presses against the clamping unit, to effect a linear forward motion of the structures of the rod against the impact direction of the impact unit.
