Abstract

In a clamping device (1), in particular vice, the clamping device comprising:

a housing (2) which is U-shaped in cross-section and in which one or two guideways (8) extending in a linear direction are incorporated,at least one base jaw (11) which is mounted in the guideway (8) and in which an internal thread (12) is provided, anda drive spindle (9) which is rotatably mounted in the respective housing (2), is arranged parallel to the guideway (8) and is driveably coupled to the respective base jaw (11),the threads (10) worked into the drive spindle (9), through which the torques from the crank are transmitted for the linear displacement of the base jaws (11), should be permanently encapsulated in a watertight and airtight manner irrespective of the position of the base jaws (11) or the drive spindle (9), and on the other hand the adjustment travel (Δs) of the base jaws (11) or clamping jaws (13) should be as large as possible in order to clamp workpieces with configurations that can be completely different without the need for time-consuming and complicated conversion measures.
