AIR SHOT PEENING DEVICE FOR INNER WALL OF HOLE

摘要

PROBLEM TO BE SOLVED: To provide a device capable of performing air shot peening treatment of an inner wall face of a hole effectively. SOLUTION: This air shot peening device 100 has a main body 110 for introducing air shot obtained by mixing a shot in high pressure air, and a base member 120 is attached to a tip of the main body 110. A support member 130 nipped and held by the base 120 and the main body 110 supports a support column 140, and a deflection member 150 is attached to a tip of the support column 140. An insertion pipe 160 attached to the base member 120 guides the air shot to spout it from a jet nozzle 166. A deflection face 154 of the jet member 150 deflects the air shot and projects it on an inner wall face 32 of a hole 30 at an angle of 80 degrees.
