Description

Description: TECHNICAL FIELD The present invention relates to an assembling apparatus for a metal plate box-shaped work.

[Conventional technology]

2. Description of the Related Art Conventionally, as a method of assembling a box-shaped work made of a metal plate, there are welding methods such as spot welding, goby folding, riveting, and bolt / nut fastening.

[Problems to be Solved by the Invention] Welding such as spot welding must be handled by a qualified person with expertise in welding, and not only can not be handled by amateurs, but also non-ferrous metal plates such as copper plates, aluminum plates, etc. It cannot be applied to a special metal plate such as a color steel plate or a combination of different metal plates.

In addition, goby fold has many restrictions on the application place, and moreover,
There is a disadvantage that the device becomes large and complicated.

In addition, the method of fastening with rivets and bolts and nuts,
Drilling is required in advance, and a separate supply device for fasteners such as rivets is required, making it difficult to reduce the size of the device, and
There is a disadvantage that it takes time to fasten each fastener.

The present invention has been developed in view of the above-mentioned drawbacks of the prior art, and its object is to handle even an amateur, small box, high work efficiency, and a versatile box. An object of the present invention is to provide a work assembling apparatus.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a press body opposed to both sides of a work assembling / conveying line, a fluid pressure cylinder for moving the press body closer to and away from the opposing direction on a guide rod, An opposing interval adjusting screw for adjusting and moving the main body on the guide rod in the above opposing direction; and an upper and lower opposed side of the press main body, the upper side being a fixed side and the lower side being a movable side. A die and a punch for locally upsetting and coupling the die, a lifting ram that is supported on the press body on an extension below the operating axis of the die and the punch so as to be able to move up and down, and that has a die or a punch connected to the upper end thereof; A thin fan-shaped space having a vertex below the elevating ram and extending in a fan shape from substantially above the vertex toward the separation direction side of the press body, and furthermore, the vertex position is set at the swing center. An assembling apparatus for a box-shaped work is provided with a swinging piston having a swinging piston which reciprocates and swings in the fan-shaped space by fluid pressure, and a power press in which the swinging piston and the lifting ram are connected by a toggle link. .

[Action]

The pair of press bodies are disposed on both sides of the work assembling / conveying line, and approach the work from both sides by a fluid pressure cylinder, and swing the swinging piston of the power press upward to form the toggle link and the lifting ram. The overlapping portion of the work is locally swaged and deformed by the die and the punch through the intermediary of the work to join both sides of the work.

When the work is joined, the swing movement of the swing piston is smoothly converted and transmitted to the linear movement of the lifting ram via the toggle link, and at the time of joining the work, the swing center of the swing piston and the toggle link are moved. The connecting pins at both ends of the upper and lower ends and the operating axis of the lifting ram are arranged in a straight line to form a dead point of the toggle link, and can exert a coupling force necessary for coupling the workpiece.

Further, the opposing interval of the press body can be adjusted by the opposing interval adjusting screw, and can be shared by works having different opposing intervals.
