SHOT PEENING DEVICE AND SHOT PEENING METHOD

摘要

A plurality of rotatable small table are disposed on a rotatable large table, and a workpiece is mounted on the small tables. Above a projection range in the large table, a pressing part is provided. The pressing part is elevated and lowered by an elevating/lowering mechanism between a withdrawn position spaced above the workpiece on the small table and a pressing position for pressing the workpiece on the small table from above. Also, the pressing part is rotationally driven coaxially with a rotary shaft of the small table and in the same rotating direction and at the same rotating speed as the small table, by a third drive mechanism.

主权项

1: A shot processing device comprising:
a projector which projects a projection material to a workpiece; a rotatable first rotary table which is disposed at a position including a projection range where the projection material is projected by the projector and a non-projection range outside the projection range; a first drive mechanism which rotationally drives the first rotary table; a plurality of second rotary tables which are disposed on the first rotary table and include a rotary shaft parallel to a rotary shaft of the first rotary table to be rotatable, and on which the workpiece is to be mounted; a second drive mechanism which rotationally drives the second rotary table; a pressing part which is provided above the projection range on the first rotary table, and which is movable up and down between a withdrawn position spaced above the workpiece on the second rotary table and a pressing position for pressing the workpiece on the second rotary table from above; an elevating/lowering mechanism which elevates and lowers the pressing part; and a third drive mechanism which rotationally drives the pressing part coaxially with the rotary shaft of the second rotary table and in the same rotating direction and at the same rotating speed as the second rotary table.
