Drilling device |
摘要 |
A drilling device with an arrangement for the detachable connection of a drill, especially a rock drill, percussion drill, hammer drill, and the like, to a receiving device, e.g. a drive head, which has a longitudinal bore for receiving the shank of the drill, and also has a driving part which is drivingly connectable to a drilling machine and is coaxial with the longitudinal bore. The drilling device furthermore comprises a drive transmitting member movable in the driving part transverse in the longitudinal bore of the receiving device. The drive transmitting or follower member is arranged to engage a bottom face of a recess in the shank of the drill. This recess has a segment-shaped cross section and has a bottom extending continuously over the entire corresponding width of the drill shank. On the driving part a securing part is mounted which is movable substantially in axial direction of the driving part into a position in which the drive transmitting member is arrested in its drive transmitting position and also into a position in which the drive transmitting member is released from its drive transmitting position and action.
