2 4. 2 Two-hand operation (the and the hand lever are operated separately) One-hand operation (the and handle lever/hand wheel are operated simultaneously) rapid stroke stroke DE-STA-CO s variable stroke straight-line clamps are used in applications where workpiece thicknesses and workpiece tolerances vary. These clamps are suitable for between ribs and hollow spaces difficult to reach. Compact design and different types of operation allow for application of the straight-line clamps in fixtures for mass production as well as for single part production. s Foot base (FO Series) (FL Series) (G Series) Type of operation Two hand operation The hand lever () and the () are separate. The hand lever is connected to the mechanism. The can be removed from the clamp One-hand operation The hand lever () or the hand wheel () and the (2) are linked. The is retained in the clamp. Clamping operation The () or (2) which is guided in the clamp body contacts the workpiece. By rotating the hand lever () or the hand wheel () clock-wise the stroke, S is engaged and the is tightly gripped by the slotted sleeve (). Operating principle The hand lever s () clock-wise rotation causes the threaded sleeve () and the conical sleeve (4) to which it is connected to move in the direction of the arrow shown in the drawing. The conical sleeve produces a force-locking connection between the slotted sleeve () and the by means of the ball bearings () located at the sleeve s perimeter. Due to the force-locking connection, the rotates and produces the. The s rotation may be compensated for by means of a swivel hold-down piece. The strokes S specified in this catalog were measured no opposing forces present while measurements were taken. When this product against a workpiece, the is reduced by the force-locking connection between the and the workpiece. The straight-action clamp is unlocked by turning the hand lever or the hand wheel counterclockwise. This method is used for both the one-hand and the two-hand operation types. This counter-clockwise rotation makes the conical sleeve (4) and the threaded sleeve () or () move backward. The pressure spring (7) pushes back the relieved ball bearings () via the pressure ring (). The force-locking connection between the slotted sleeve and the can be moved freely again. Straight-line clamps which are two-hand operated can also be applied to pull actions when the is inserted in the clamp s housing in the opposite direction. On the one hand operated clamp, the rotation inducing the is directly transmitted from the (2) or the hand wheel to the threaded sleeve () via a groovespring connection. The and un operations are executed in the same way as described before. Handling To change the position of the handle while in the clamped or the unclamped position, pull the hand lever off its spline () and set it in the desired position. The holding forces specified in the catalog refer to the maximum load exerted on the clamp by counter-forces. For details concerning the force FS exerted on the workpiece by the clamp and depending on the operation force FB (manual force), please see the chart on the next page. The force is proportional to the operation force.the achieved force must not exceed the maximum holding force. As the straight-line clamps, the exception of the F-0 model, are designed only for axial load, we recommend to use an additional radial support for the in the event of side load.
