Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding apparatus for welding parts having holes such as a hexagonal nut, a ring having an internal thread on the inner peripheral side, and a washer in conformity with the holes provided in a thin metal plate.

[0002]

2. Description of the Related Art For example, a hexagon nut is welded to a metal thin plate at a connecting portion when the work is made by using a metal thin plate having a thickness of about 1 mm and is joined to other members or parts are mounted. In this case, a hole 1a is provided in the metal thin plate 1 as shown in FIG. 11, and the hexagon nut 2 is combined with the hole 1a of the metal thin plate 1 to form all or part of the six sides of the hexagon nut 2 and the metal thin plate as shown in FIG. Weld the corner with 1 and WE
A screw member for inserting a hole of another member is screwed into the hexagon nut 2 welded to the metal thin plate 1 and the other member, or another component is attached. A washer is attached to the hole of the thin metal plate with a washer (seat plate) or the like, and the thin metal plate 1 is reinforced as a contact surface of the seat surface of the bolt head.

[0003]

Before welding, it is necessary to first position a holed part such as a hexagon nut or washer in a hole of a thin metal plate. When positioning a holed part in a hole in a thin metal plate, it is difficult to position it only with your fingertips, and even if you position it, the part with a hole is a small part, so the welding rod touches the part with a hole during welding. In addition, the blown gas from welding, the scattering of spatter, or the magnetism generated in the case of direct current welding causes parts with holes to move. Therefore, as shown in FIG. 10, a worker usually uses a single pin-shaped welding jig that fits the hole 1a of the thin metal plate 1 and a part having the hole, in this case, the inner diameter 2a of the hexagon nut 2, that is, the inner diameter of the female screw. Make 30,
The pin-shaped welding jig 30 is welded while being fitted in the hole 1a of the thin metal plate and the inner diameter 2a of the hexagon nut 2. In this case, the welding jig 30 is a pin with a single diameter d that fits into the inner diameter 2a of the hexagon nut 2. The diameter of the hole 1a of the thin metal plate 1 is larger than the root diameter d1 of the female screw of the hexagon nut 2. The hole 1a of the metal thin plate 1 is larger than the diameter d of the welding jig 30.
Has a large diameter, the hexagon nut 2 can move even if the pin-shaped welding jig 30 is fitted into the inner diameter 2a of the hexagon nut 2 and the hole 1a of the metal thin plate 1. Incorrectly positioned in position.

Therefore, assuming that the welding jig 30 is a stepped pin and has a diameter d that fits into the inner diameter 2a of the hexagon nut 2 and a diameter that fits exactly into the hole 1a of the thin metal plate 1, this welding jig 30
Since it cannot be inserted from the hexagon nut 2 side, it may be possible to insert the thin metal plate 1 from the lower side with the portion having the thin diameter d facing up, but since the metal thin plate 1 is placed on a metal grounded table, this With such a stepped welding jig 30, the workability becomes extremely poor.

In order to avoid such a difficulty, as shown in FIG. 12, the hole 1a of the thin metal plate 1 is made slightly larger than the above, and a cylindrical fitting portion which is tightly fitted in the hole 1a is formed on the bottom side of the hexagon nut 2. 2b is provided, the fitting portion 2b of the hexagon nut 2 is inserted into the hole 1a of the thin metal plate 1 before welding, and welding WE is performed. By doing so, the machining accuracy of the hole 1a of the thin metal plate 1 is increased, and the fitting portion 2b of the hexagon nut 2 is also closely fitted in the hole 1a. Therefore, the processing accuracy must be improved. Therefore, in this case, the cost is increased.

As described above, whichever method is adopted, one of the problems is that the positioning accuracy is not good, the workability is poor, or the cost is high. Also, any of the above methods is not suitable for mass production.

It is an object of the present invention to provide a welding apparatus capable of accurately positioning a component having a hole in accordance with the position of a hole in a thin metal plate, having good workability, low cost and suitable for mass production.
