Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a welding torch holding device suitable for welding and fillet welding of thick base materials.

[Conventional technology]

Conventionally, groove joint welding of thick base metals requires 1
This is accomplished by using a single electrode using a single torch, by stacking a large number of bead layers, or by weaving.

[Problem that the invention attempts to solve]

Therefore, since there is only one electrode, efficiency is poor and fillet welding cannot be performed.

[Means for solving problems]

This idea was made with the above points in mind, and consists of a base for mounting to the weaver, and two horizontal inverted U-shaped pieces that are arranged in parallel with one end fixed to the upper and lower parts of the base. a guide block provided between the rear portions of one end of the two frame bodies, a threaded rod block provided between the rear portions of the other end of the two frame bodies; A support block provided between the other ends, a guide plate provided between the other ends of both the frames, a first holding cylinder that holds the first torch, and one end of the first holding cylinder. a guide rod that extends and is inserted into the through hole of the guide block; a receiving member that extends to the other end of the first holding cylinder; and a receiving member that passes through the guide block and the guide plate. screwed into the screw hole of the first
A threaded rod that moves the holding cylinder back and forth, a bearing member fixed to the support block, a second holding cylinder that holds the second torch, and the bearing member that extends to the side of the second holding cylinder. This welding torch holding device includes a horizontal shaft inserted into a horizontal hole so as to be movable and rotatable in the left-right direction, and a screw body for fixing the horizontal shaft to the bearing member.

[Effect]

Therefore, according to this invention, since the first holding tube and the second holding tube are provided for holding the first torch and the second torch, respectively, welding efficiency is high, and moreover, the first holding tube is connected to the threaded rod. Since it is movable back and forth, and the second holding cylinder is movable left and right and rotatable using a screw body, it is easy to adjust the position of the two torches, and fillet welding is possible. Moreover, the structure is extremely simple and can be manufactured at low cost.

〔Example〕

Next, this invention will be explained in detail with reference to drawings showing one embodiment thereof.

In those drawings, 1 is a mounting bracket for the weaver, 2 is a base for mounting the weaver fixed to the bracket 1 with bolts 3, and 4 and 5 are horizontal structures with one end fixed to the upper and lower parts of the base 2 and arranged in parallel. Two inverted U-shaped frames in the state, 6 is both frames 4 and 5
A guide block provided between the rear ends on one end side, 7 a threaded rod block provided between the rear ends on the other end side of both frames 4 and 5, and 8 between the other ends of both frame bodies 4 and 5. Each of the blocks 6, 7, 8 maintains the distance between the frames 4, 5.
Reference numeral 9 denotes a guide plate provided between the other ends of both frames 4 and 5.

10 is a first holding cylinder that holds the first torch; 11
12 is a thumb screw inserted into the first holding cylinder 10 and fixes the first torch; 12 is a guide rod extending to one end of the first holding cylinder 10 and inserted into the through hole 13 of the guide block 6; 14 is a thumbscrew; A receiving member 15 extends from the other end of the first holding cylinder 10 to a guide block 7.
and a threaded rod 17 that penetrates the guide plate 9 and is screwed into the screw hole 16 of the receiving member 14 to move the first holding cylinder 10 back and forth; A blocking nut 18 is a knob of the threaded rod 15 provided at the rear end of the threaded rod 15, and 19 is a washer.

20 is a bearing member fixed to the support block 8; 21 is a second holding cylinder that holds the second torch;
2 is a screw with a handle that fixes the second torch inserted into the second holding cylinder 21; 23 is extended to the side of the second holding cylinder 21 and is movable in the horizontal direction and rotatable in the horizontal hole of the bearing member 20; The horizontal shaft 24 inserted through is a screw body that fixes the horizontal shaft 23 to the bearing member 20.

In the fixed position state, the first holding cylinder 10 and the second holding cylinder 21 are on the same straight line with respect to the base body 2, and the rotation of the threaded rod 15 causes the receiving member 14 screwed to the threaded rod 15 to move back and forth. and guide rod 12
is guided by guide block 6, so
The first holding cylinder 10 moves back and forth.

Next, when the screw body 24 is loosened, the horizontal shaft 23 is movable and rotatable left and right on the bearing member 20, so that the second holding cylinder 21 is movable and rotatable left and right.

Therefore, the first holding cylinder 10 and the second holding cylinder 21 holding the first torch and the second torch, respectively, can be moved in a predetermined position and direction with respect to the base body 2.

[Effect of idea]

As described above, according to this invention, since the first holding tube and the second holding tube are provided for holding the first torch and the second torch, respectively, welding efficiency is high, and the first holding tube is attached to the threaded rod. Since the second holding cylinder is movable back and forth by the screw body, and the second holding cylinder is movable left and right and rotatable by the screw body, it is easy to adjust the position of the two torches, and fillet welding is possible. Moreover, the structure is extremely simple and can be manufactured at low cost.
