Claims

[Scope of utility model registration request]

In a work clamp device that clamps a part of a workpiece positioned and held at a machining position to prevent the workpiece from swaying during machining, a workpiece clamping device is provided that is swingable to the clamp position and is provided facing each other, and that is attached to a part of the workpiece. A pair of clamp arms that abut and clamp, a pair of wedge members that are provided in sliding contact with each of the clamp arms and swing to open and close each clamp arm, and each wedge member that is provided in sliding contact with each of the wedge members. a tilted guide member that guides the wedge member; a swinging arm that rotatably supports the end of each of the wedge members; and an operating member that swingably supports the swinging arm at a central portion between the support portions; A work clamping device comprising a driving means for moving the operating member.
