DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding apparatus and, more particularly, to a welding apparatus for welding a flat plate and a joint of a standing plate erected on the flat plate.

[0002]

2. Description of the Related Art Conventionally, welding is generally performed manually by an operator. However, welding was a severe task, and workers were apt to hurt their eyes and hips. For this reason, various automatic welding devices have been proposed.

[0003]

However, the conventional automatic welding apparatus is large in size and high in cost. In addition, the conventional automatic welding apparatus has a problem of low versatility, such as difficulty in welding a flat plate and a standing plate erected on the flat plate in a lattice shape in the X and Y directions. Therefore, an object of the present invention is to provide a small, compact, and highly versatile welding apparatus.

[0004]

For this purpose, the present invention provides a roller 4 for pressing the standing plate 102 from a horizontal direction , pressing means 8 for pressing the roller 4 against the standing plate 102, and a flat plate 101. A welding device is constituted by a grounding wheel 10 that is grounded, a motor 2 that rotates the roller 4 and / or the grounding wheel 10, and a torch 12 that penetrates the roller 4 in an inclined posture.

[0005]

According to the above construction, the joint between the flat plate 101 and the upright plate 102 is welded by the torch 12 while the roller 4 rolls along the length of the upright plate 102.

[0006]

【Example】

(Embodiment 1) Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of the welding device, FIG. 2 is a side view,
FIG. 3 is a plan view. This welding device comprises a flat plate 101,
On this flat plate 101, upright plates 102 (102a, 102b) erected in a lattice shape in the X and Y directions are welded. Reference numeral 1 denotes a bracket on which a motor 2 is installed. 13 is a power supply cord, and 14 is a switch.

[0007] A ring-shaped bearing 3 is provided on the bracket 1, and a roller 4 is mounted on the bearing 3. A gear 5 is formed integrally with the roller 4, and the gear 5 is driven by the motor 2 via a gear 6. A magnet 8 as a pressing means is mounted on the lower surface of the bracket 1, and the magnetic force shown in FIG.
As described above, the roller 4 presses the upright plate 102 from the horizontal direction . 9 is a positioning roller and 10 is a grounding wheel. When the motor 2 is driven, the rollers 4 rotate, and the apparatus is mounted on the upright 1
Move along 02.

[0008] As shown in FIG .
2 penetrates in an inclined posture . When the roller 4 is pressed against the upright plate 102 by the magnetic force of the magnet 8, the tip of the torch 12 faces the joint a between the flat plate 101 and the upright plate 102. Reference numeral 13 denotes a fixture for the torch 12.
Is attached to the cover case 15.

The apparatus is set on the flat plate 101, and the switch 14 is turned on. Then, the motor 2 is driven and the roller 4 is rotated. Then, the apparatus moves along the standing plate 102a and welds the flat plate 101 and the standing plate 102a. When the limit switch 11 hits the upright plate 102b in the Y direction, the motor 2 stops driving or starts reverse rotation and returns to the original position.

(Embodiment 2) In FIGS. 4 and 5, a bracket 23 is provided with a frame 23, and an arm 25 is
Are connected. A roller 26 is mounted on the lower end of the arm 25. The frame 23 and the arm 25 are connected by a spring 27, and the roller 4 and the roller 26
Hold the upright plate 102a by its spring force. Therefore, when the motor 2 is driven, the apparatus welds the joint a between the flat plate 101 and the upright plate 102 while moving along the upright plate 102a. The arm 25 is rotated as shown by the chain line in FIG. 5 to set it on the standing plate 102 and to remove it from the standing plate 102.

The present invention is not limited to the above embodiment. For example, the apparatus may be controlled by a computer under NC control, or the bracket 1, the roller 4, the grounding wheel 1
The roller 4 may be pressed against the upright plate 102 by forming a component such as 0 with a magnet.
02, so long as it can be positioned so that the torch 12 faces the joint between the flat plate 101 and the upright plate 102.

[0012]

As described above, according to the present invention, a compact, compact and highly versatile welding apparatus can be obtained, for example, in particular, a standing plate erected in a lattice can be advantageously welded.
