Objects of different sizes and shapes are gripped in a monostable manner by an apparatus which has a single pneumatic power source and has interchangeable jaw assemblies attached to an operating mechanism that provides a linear motion to engage the object. The gripping jaws are selected from a set of three basic types of generic jaws, i.e., nose-shaped jaws and vee-shaped jaws for curved surfaces, and rest button jaws for flat surfaces. Various turbine blades, for instance, are grasped by the airfoil and root using different combinations of these jaw types and have a predictable location relative to the gripping device.

A gripping device which grasps a wide variety of objects comprising: a pair of jaw assemblies each having at least one gripper jaw selected from a set of generic jaws which in different combinations are adapted to grasp objects of many sizes and shapes and inlude nose-shaped jaws primarily for concave and concave/convex surfaces, vee-shaped jaws primarily for convex surfaces, and multiple rest button jaws for flat surfaces; an operating mechanism to which said jaw assemblies are removably and interchangeably attached and which has means for providing relative linear motion of said jaw assemblies between open and closed positions in response to actuation of a power source to grip an object in a monostable manner; wherein every jaw assembly includes a mounting base and one or more brackets adjustably mounting at least one gripping jaw on said base; and said nose-shaped jaws have a radius of curvature in two directions forming a contact area which has the shape of a section of a toroid, said vee-shaped jaws have two contact areas that intersect and are each a sector of a cylinder, and said multiple rest button jaws have a flat mounting plate with an array of holes in which are three spherical rest buttons.
