A low cost chip collector with high chip collection performance includes a cover case 2. The cover case 2 includes a holding part 2a and a discharge hole 23a discharging air in the holding part 2a. An air suction device 7 discharges compressed air through a discharge opening 53. The air suction device 7 places a part, of the discharge hole 23a, near the holding part 2a. The air suction device 7 sucks air in the holding part 2a. The discharges the air through the discharge hole 23a. A first ring-shaped protrusion 51 is provided on a part, of the discharge opening 53, near holding part 2a, protrudes in a direction away from the holding part 2a, and covers the discharge opening 53. |

1. A chip collector for collecting chips generated when an end of an electrode tip for spot welding is cut by a cutting edge of a tip dresser, the chip collector comprising:
a cover case including
a holding part that holds the tip dresser, anda discharge hole that communicates with the holding part and discharges air in the holding part; an air suction device
including a discharge opening through which compressed air is discharged and which is disposed on an inner surface of the discharge hole,discharging the compressed air through the discharge opening in a direction away from the holding part along the discharge hole,placing a part, of the discharge hole, near the holding part under negative pressure,sucking the air in the holding part, anddischarging the air through the discharge hole; and a chip collection device
connected with the discharge hole, andcollecting chips that move with the air sucked by the air suction device,wherein
a ring-shaped protrusion
is provided on a part, of the inner surface of the discharge hole, from the discharge opening toward the holding part,protrudes in a direction away from the holding part, andcovers the discharge opening. |
