ABSTRACT:
A vise with a clamp having a housing with clamp fingers and load transfer elements enabling the fingers to move relative to each other to compensate for tolerance variations between workpieces simultaneously clamped or contour variations in a workpiece. Each finger is elongate and reciprocable relative to the housing. Preferably, each element is disc-shaped and can be constructed and arranged to interlock with other elements to promote clamp stability. The elements are constructed and arranged within the housing in a first row of elements behind the clamp fingers and a second row of elements behind the first row and can move relative to each other. Preferably, there are the same number of elements in the first row as there are clamp fingers and one less element in the second row. To encourage stability, the housing preferably has inwardly extending dividers between fingers and inwardly extending sidewall portions that can be inwardly inclined to form an element guide surface. In a second embodiment, the clamp consists of inner and a pair of outer modular clamp units that are connected to form an assembly. Each modular unit has a finger, load transfer elements, and at least one load communicating element that extends from one unit to an adjacent unit for enabling units to be joined to form a clamp having a desired number of fingers. In a method of this invention, fingers and elements of the clamp move relative to each other to clamp an unevenly contoured workpiece.
