Then, a fixing member 2 having a U-shape in a side view is fitted on the upper edge of one of the plates 1 to be welded, and is fixed to the plate 1 to be welded by a clamp 3. A slider 4 is arranged on the fixed member 2, and a slide member 5 is installed on the slider 4 so as to be slidable in a direction (Y direction) orthogonal to the plate 1 to be welded. The slide member 5 is moved to the slider 4 by rotating the handle 6 clockwise or counterclockwise.
The position of the slide member 5 with respect to the slider 4 is fixed by a clamp 7, and the fixation is released.

A table 9 is fixed to the slide member 5, and a column 8 is supported on the table 9 at its lower end by a rotary shaft 8a perpendicular to the plate 1 to be welded. On the other hand, the tip end of the handle 10 is locked to the upper end of the column,
By rotating the handle 10 clockwise or counterclockwise, the column 8 swings about a rotation axis 8a in a vertical plane parallel to the plate 1 to be welded. A base 11 is fixed to the upper portion of the support column 8, and a moving member 14 is supported on the base 11 so as to be movable in the horizontal direction (X direction) along the surface of the plate 1 to be welded. An arm 12 is fixed to the base 11, and this arm 12
By the forward and reverse rotations of the handle 13 attached to, the moving member 14 is driven and moves in the X direction.

A torch support portion 15 is provided at the end of the moving member 14.
Is erected. A torch grip 25 is inserted into and supported by the torch support portion 15. Further, when the nozzle 23 is adjusted up and down, the handle 10 is rotated so that the table 1
The inside of 1 is moved along the axis of this handle in the X-axis direction moving member 14
And the arm 12 moves in the Z-axis direction. Furthermore, the nozzle 2
When attaching / detaching 3 to / from the nozzle support base 21,
When 7 is loosened, the base 11, the moving member 14 and the arm 12 pivot on the column 8 about the axis of the handle.

On the other hand, a support member 20 is supported at the tip of the moving member 14 via a rotary shaft 18 parallel to the Y direction. By loosening the handle 19, the angle of the support member 20 around the rotation shaft 18 can be adjusted. The support member 20 includes a tip portion of the torch 24 and the nozzle 2
A nozzle support member 21 for fixing the upper end portion of 3 is attached, and by operating the lever 22, the tip end portion of the torch 24 and the upper end portion of the nozzle 23 can be removed from the nozzle support member 21.

In the conventional vertical welding apparatus thus constructed, the fixing member 2 is fixed to the plate 1 to be welded, and then the torch 24 is fixed to the torch supporting member. Furthermore, lever 1
7 is loosened, and the base 11, the moving base 14, and the arm 12 are swung on the support column 8 about the axis of the handle, and the nozzle support base 2
The nozzle 23 can be easily attached to the nozzle support base 21 by retracting the nozzle 1 from the narrow groove (welding portion) of the plate to be welded to the front open space. Then, the handle 6 is operated to adjust the Y direction position of the nozzle 23, the handle 13 is operated to adjust the X direction position of the nozzle 23, the handle 13 is operated to adjust the Z direction position of the nozzle 23, The nozzle angle is roughly adjusted by operating the handle 10, and the nozzle angle is finely adjusted by operating the handle 19.

However, in the conventional vertical welding apparatus thus constructed, the fixing member 2 fixes the apparatus main body to the work piece 1 to be welded. Applicable only to plates placed in, not to horizontal planes. That is, the conventional vertical welding device is exclusively for so-called bottom longe and cannot be applied to top longe and deck longe.

Further, in order to set the nozzle 23 in the long groove after installing the apparatus main body on the plate 1 to be welded and align the nozzle tip with the welded part, it is necessary to freely adjust the nozzle angle. However, in the conventional device, the plate to be welded 1
Although the angle can be adjusted in the plane parallel to, by the handles 10 and 19, the angle cannot be adjusted in the plane orthogonal to the plate 1 to be welded. Therefore, the position of the tip of the nozzle in the Y direction must be adjusted by adjusting the handle 6. Therefore, the angle adjustment of the nozzle is extremely complicated.

Further, the plate thickness is often different depending on the type of the material to be welded. In that case, the clamp 3 is tightened to fix the fixing member 2 to the plate 1 to be welded, and then the clamp 7 is released to release the handle. It is necessary to operate 6 to move the slide member 5 in the Y direction and position the nozzle 23 at the center of the plate thickness. However, there is a drawback that this position adjustment is not easy.

Furthermore, conventionally, since the torch 24 is connected to the nozzle support member 21 by screwing the screw provided at the tip of the torch 24 into the screw portion provided on the nozzle support member 21, the torch 24 is connected. In order to attach / detach to / from the nozzle support member 21, it is necessary to rotate the entire torch 24 in accordance with the screw, which has a drawback that the operation is complicated.

The present invention has been made in view of the above problems, and it is easy to adjust the nozzle angle and also to adjust the nozzle position even when the materials to be welded have different thicknesses. It is an object of the present invention to provide an upright welding apparatus that can be easily attached to the apparatus, can be attached to a flat surface, and can be applied to a wide range.
