Title:
PEENING DEVICE AND PEENING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/057961
Kind Code:
A1
Abstract:
A peening device is provided with: peening impact pins that impact on a surface to be worked; a device main body that uses vibration to move the peening impact pins back and forth with respect to the surface to be worked; servo motors (22x, 22y) that adjust the inclination of the device main body with respect to the surface to be worked; laser displacement gauges (20A, 20B, 20C, 20D) that detect the device angle; and a vibration sensor (18) that detects the vibration state of the device main body. Furthermore, a control device (40) for the peening device controls the servo motors (22x, 22y) such that the vibration state detected by the vibration sensor (18) is a predetermined vibration state. Thus, the peening device carries out excellent peening by conforming to the surface to be worked, the shape of which changes from moment to moment because of the peening.
