Boring device, to form bores using borer tubes, has holder unit with rotation plate for borer tube having radial locking opening and has locking unit on plate with locking bolt to lock borer tube

摘要

The device (10) has a rotating bore drive (16) and a holder unit (18) with a rotation plate for a borer tube (40) with at least one radial locking opening (42). A locking unit on the rotation plate has at least one radially sliding locking bolt, which is moved between locked and unlocked positions by an axially sliding adjustment element. In the locked position, the locking bolt engages the locking opening to form a positive connection. The adjustment element has an axially sliding adjustment rod, whose end furthest from the locking bolt is guided along a control slide-way. The slide-way has a wedged profile in its axial and peripheral directions and rotates relative to the rotating plate, so that rotating the control slide slides the control rod axially and operates the locking bolt.
