Abstract
A shot peening device includes a turntable which rotates about a revolution axis, holding mechanism which moves with the turntable, pressure mechanism which compresses a coil spring, rotation mechanism which rotates the coil spring, projection mechanism which projects shots to the compressed coil spring, load cell which detects a load applied to the coil spring, and controller. A signal output from the load cell is input to the controller, and the controller detects a chronological change of the load applied to the coil spring during the shot peening.
Claims12
A shot peening device comprising:
- a turntable mechanism including a turntable which rotates around a revolution axis;
- a revolution mechanism which rotates the turntable mechanism;
- a holding mechanism which holds a lower end turn portion and an upper end turn portion of a coil spring while the coil spring is kept standing and moves around the revolution axis with the turntable;
- a rotation mechanism which rotates the holding mechanism around a rotation axis;
- a pressure mechanism which compresses the coil spring in a state where the coil spring is held by the holding mechanism;
- a load detector which detects a load applied to the coil spring by the pressure mechanism;
- a projection mechanism which projects a shot to the compressed coil spring;
- and
- a controller which detects a change in the load based on a signal output from the load detector.
