Wrench Adapter

Controlled force is applied to the shaft of a tested part by a conventional torque wrench through an adapter.

In Figs. 1 and 2, the adapter is engaged by the socket of the torque wrench and the cam track is rotated until three grips close on the part's shaft, the part being restrained from movement by a part holder. The wrench rotates the cover and top plate relative to the manually restrained cam track to rotate the grips about their pins, forcing the cams against the cam followers. In Fig. 3, springs replace the cams, cam followers and cam track.

The greater the applied torque, the greater the force exerted on the shaft of the tested part. The direction of rotation can be reversed by reversing the grips' positions on their pins. Any shape of shaft may be gripped. If the shaft is a soft material, an appropriate grip material, such as nylon, should be used.

Other applications are made possible by, for example, adding a handle directly to the gripper body and using the adapter directly as a wrench.
