Abstract

According to the present invention, there is provided a wire aiming guide capable of further improving usability. The present invention provides a wire aiming guide ( 1 ) configured to guide a welding wire (W) and feed the welding wire from a tip side thereof while being attached to a welding torch including: a first guide member ( 2 ) and a second guide member ( 3 ) configured to guide the welding wire (W): and a connecting portion ( 5 ) rotatably connecting the first guide member ( 2 ) and the second guide member ( 3 ), wherein a direction of the welding wire (W) fed from a tip end side of the first guide member ( 2 ) is adjusted by bending the first guide member ( 2 ) with respect to the second guide member ( 3 ).

First claim

The invention claimed is:

1. A wire aiming guide configured to guide a welding wire and feed the welding wire from a tip side thereof while being attached to a welding torch comprising:
a first guide member and a second guide member configured to guide the welding wire:
a connecting portion rotatably connecting the first guide member and the second guide member; and
a fixing portion configured to fix the first guide member to the second guide member;
wherein a direction of the welding wire fed from a tip end side of the first guide member is adjusted by bending the first guide member with respect to the second guide member, and
the fixing portion includes:
a fixing bolt;
a guide slit which is configured to allow the fixing bolt to pass therethrough and is formed on the first guide member;
a third shaft hole which is configured to allow the fixing bolt to pass therethrough and is formed on the second guide member; and
a nut which is configured to fasten to a tip end side of a shaft portion of the fixing bolt.

2. The wire aiming guide according to claim 1 , wherein a nozzle portion configured to penetrate the welding wire is provided on the tip side of the first guide member, and the welding wire is fed out from the tip of the nozzle portion.

3. The wire aiming guide according to claim 1 , wherein a first guide portion configured to guide the welding wire toward the nozzle portion side is provided with the first guide member.

4. The wire aiming guide according to claim 3 , wherein the first guide portion is positioned on both side of the welding wire so as to sandwich the welding wire, and the welding wire is guided toward the nozzle portion side while being sandwiched by the first guide portion.

5. The wire aiming guide according to claim 1 , wherein the wire aiming guide further includes a liner configured to feed the welding wire in a state of being connected to a base end side of the second guide member.

6. The wire aiming guide according to claim 5 , wherein the second guide member is provided with a second guide portion configured to guide the welding wire fed from the liner.

7. The wire aiming guide according to claim 6 , wherein the second guide portion is positioned on both sides of the welding wire so as to sandwich the welding wire, and the welding wire is guided toward the first guide member side in a state of being sandwiched by the second guide portion.

8. The wire aiming guide according to claim 1 , wherein the wire aiming guide further includes an attaching portion configured to attach the second guide member to the welding torch.

9. A welding device comprising a welding torch and a wire aiming guide according to claim 1 .
