This invention relates to a clamping element for workpieces, in particular a vice (10, 33, 40), comprising a first clamping jaw (12, 34, 41) and a second clamping jaw (13, 35, 42), which are mounted on a carriage bed (11). To avoid bending moments as a result of tensile forces acting on the carriage bed (11), the clamping element of the invention is characterized in that the resultants of the forces introduced by the clamping jaws (12, 13, 34, 35, 41, 42) into the carriage bed (11) as a result of the clamping forces acting on the clamping jaws (12, 13, 34, 35, 41, 42) are located in the plane of the neutral fiber (32) of the carriage bed (11). Preferably, the clamping jaws (12, 13, 41, 42) constitute two-armed levers, a clamping surface (21, 24) being associated to the one lever arm and a push rod (27, 46) engaging the other lever arm.
A clamping element for a vice, comprising a first clamping jaw and a second clamping jaw, which are mounted on a carriage bed, wherein the first clamping jaw, the second clamping jaw, or a combination thereof is supported on a carriage bed by one pivot pin each, wherein a plurality of bores is provided in the carriage bed so that by changing the pivot pins from one bore to the other the first clamping jaw, the second clamping jaw, or both the first and second clamping jaw can be displaced along the carriage bed, in which the bores for the pivot pins are arranged in a neutral axis of the carriage bed, wherein the resultants of the forces introduced by the clamping jaws into the carriage bed as a result of the clamping forces acting on the clamping jaws are located in the plane of the neutral axis of the carriage bed.
