发明名称 Gewindebohrvorrichtung zum radialen Gewindebohren
摘要 A tapping attachment for use in connection with radial tapping comprises a tap spindle member (34) rotatable in a tapping direction, a driven part (20) engageable with a driving (16) part from a power source in a different direction from the tapping direction, a forward drive member (28) engageable with the tap spindle member (34) to drive the tap spindle member in the tapping direction, a reverse drive member (30) engageable with the tap spindle (34) to drive it in a direction opposite to the tapping direction, means (24,26) for transmitting drive to the forward drive member (28) and the reverse drive member (30) and engageable with the driven part (30) for receiving drive and with the tap spindle member. The forward drive member (28) and the reverse drive member (30) are moveable axially along the tapping direction relative to the tap spindle member (34) and upon relative axial movement in a direction opposite to the tapping direction, the forward drive member disengages from the tap spindle member and the reverse drive member engages in driving engagement with the tap spindle member to impart reverse rotation to the tap spindle member. <IMAGE>
