| 摘要 |
The invention relates to a pivotable tool-changing arm with tool grippers arranged at one end or at both ends, which is pivotable through 180@ about its one end or about its mid-axis and which carries the tools parallel or perpendicularly to or in the mid-plane of the arm end or arm ends, the end positions of the tool or tools being located in two parallel planes. It is characterised in that, in order to change a tool or to change two tools simultaneously in two end positions (1, 1a) with longitudinal axes (F) of the tool or tools (W) located at an angle to one another, the pivot axis (7) of the arm (10, 11) is inclined relative to the longitudinal mid-plane (M) of the arm or of one arm half (10, 11) and the pivot axis (7) is located on the angle-bisecting line between the two end positions (1, 1a). <IMAGE>
