Machine for deep rolling tool positioning

摘要

A device and methods are provided for deep rolling. In one embodiment, a machine includes a deep rolling tool having a plurality of rolling elements, wherein each rolling element is mounted at the distal end of a fork arm, and wherein the rolling elements are configured to apply a compressive stress to articles received by the deep rolling tool. The machine may also include a positioning element coupled to the deep rolling tool, wherein the positioning element is configured to position the deep rolling tool and apply the deep rolling tool to an article.

1. A machine, comprising:
a deep rolling tool comprising;
a flexible first fork arm and a flexible second fork arm each extending outwardly from a base section;a first rolling element rotatably secured to a distal end of the flexible first fork arm;a second rolling element rotatably secured to a distal end of the flexible second fork arm, wherein the flexible first fork arm and the flexible second fork arm are configured to locate the first rolling element and the second rolling element in a facing spaced relationship with respect to each other and wherein the flexible first fork arm and the flexible second fork arm extend outwardly from the base section without a pivot such that movement of the distal end of the flexible first fork arm with respect to the distal end of the flexible second fork arm is dependent upon a flexural stiffness of the flexible first fork arm and a flexural stiffness of the flexible second fork arm; and a positioning element operatively coupled to the deep rolling tool, wherein the positioning element is configured to apply the first rolling element and the second rolling element to opposite sides of an article.
