Abstract

Herein is described a percussion device (1) adapted for rock drilling comprising a controller (3) , a percussion mechanism (5), a percussion means (7) and a drill bit (9). The percussion mechanism (5) is adapted to provide the percussion means (7) with a motion. The controller (3) is arranged to control the percussion mechanism (5) such that it imparts the percussion means (7) with a force causing the motion, whereby the percussion means (7) during drilling impacts the drill bit (9), or a drill string (11) connected to the drill bit (9), with an impact force having a specific magnitude. The controller (3) is furthermore arranged to continuously during drilling determine a desired magnitude of the impact force of the percussion means (7) and control the percussion mechanism (5) such that the impact force of the percussion means (7) is changed according to the desired magnitude.A method for controlling a percussion mechanism (5) of a percussion device (1) is also described.
