Abstract

An object is to enable accurate machining by enabling shots to be accurately blasted on a workpiece even while workpiece is being deformed. A part manufacturing system includes: a peening device including a nozzle that projects a plurality of shots toward a workpiece, and a sensor that detects a distance to the workpiece; and a machining robot including a hand to which the peening device is attached, and a control unit that adjusts a position or an orientation of the peening device by controlling the hand based on the distance detected by the sensor.

First claim

The invention claimed is:

1. A part manufacturing system comprising:
a peening device comprising:
a nozzle section that comprises:
a pair of nozzles each disposed on a respective side of a workpiece and that projects;

a detection unit that detects a distance to the workpiece;
a protection section that is attached to a cover of the peening device and that covers a part of the workpiece; and
a pair of reflection plates that reflects the shots and turns flow directions of the shots projected from the nozzles toward the workpiece; and

a robot device comprising:
a hand section to which the peening device is attached; and
a control unit that adjusts a position or an orientation of the peening device by controlling the hand section based on the distance detected by the detection unit, wherein

the shots projected by the pair of nozzles and reflected by the pair of reflection plates hit the workpiece from both sides of the workpiece.

2. The part manufacturing system according to claim 1 , wherein
the workpiece is an elongated member,
at least two detection units are provided as the detection unit, and
the control unit adjusts the position of the peening device based on an average distance to the workpiece that is calculated from the distances detected by the at least two detection units.

3. The part manufacturing system according to claim 1 , wherein
the workpiece is an elongated member,
at least two detection units are provided as the detection unit, and
the control unit adjusts the orientation of the peening device based on a tilt angle of the workpiece that is calculated from the distances detected by the at least two detection units.

4. The part manufacturing system according to claim 1 , wherein
the peening device further includes a blocking section that can be installed at a passage section where the shots pass through from the nozzle section to the workpiece, and that can be installed outside the passage section, and
when installed at the passage section, the blocking section reflects the shots projected from the nozzle section, in a direction different from a direction toward the workpiece.
