Description

Technical Field

[0001] The present invention belongs to the technical field of connection in sheet metal structures, and particularly relates to a metal box structure formed by rapid self-positioning riveting. Background Art

[0002] Currently, in the existing assembly processes of the sheet metal industry, the connection methods between parts mainly include screw connection, rivet connection, and welding connection; these connection methods all have one or several different technical defects; screw connection requires tapping, is prone to slipping of the thread and wastes time, increases costs and is also prone to failure; although ordinary rivet connection is fast, it also occupies space, especially the parts below the rivet must reserve a flange for bearing the rivet hole, which greatly wastes materials and assembly space; welding connection cannot avoid problems such as easy rusting and stress deformation in the welding area. Summary of the Invention

[0003] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a metal box structure formed by rapid self-positioning riveting.

[0004] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0005] A metal box structure formed by rapid self-positioning riveting, including an upper cover plate, a lower cover plate, a left side plate, and a right side plate. The upper cover plate and the lower cover plate are both provided with rivet holes at the four corners. Two square holes are symmetrically arranged in the rivet holes. A plurality of riveting terminals are provided on the upper and lower sides of the left side plate and the right side plate. The riveting terminals protrude from the edges of the left side plate and the right side plate. The positions and dimensions of the riveting terminals and the square holes are all matched. The left side plate and the right side plate are provided with riveting relief openings below the riveting terminals. The riveting terminals are respectively arranged on both sides of the mouth of the riveting relief opening. The riveting terminals are provided with blocks protruding from the riveting relief opening. The rivet holes and the riveting terminals are jointly matched with rivets.

[0006] Further defined, the rivet hole is a conical counterbore. Such a design facilitates positioning of the rivet.

[0007] Further defined, the width dimension of the block is two to three millimeters larger than the diameter dimension of the rivet head of the rivet. Such a design has a good clamping and fixing effect.

[0008] Further defined, the riveting terminal is provided with a groove. Such a design serves the purpose of making way and preventing interference with the rivet hole.

[0009] Further defined, there are at least two riveting terminals, which are evenly arranged on the upper and lower sides of the left side plate and the right side plate. Such a design ensures the clamping installation strength.

[0010] Further limit that the length dimension of the riveting terminal is smaller than the depth dimension of the rivet hole. Such a design can prevent the rivet from protruding from the rivet hole and causing interference.

[0011] Further limit that the upper cover plate, lower cover plate, left side plate and right side plate are cold-rolled steel plates or galvanized steel plates or stainless steel plates. Such a design can ensure strength.

[0012] Further limit that the rivet is a countersunk blind rivet. Such a design has a good matching effect, and after riveting, it will not protrude from the surfaces of the upper cover plate and the lower cover plate.

[0013] Further limit that the surfaces between the riveting terminal and the left side plate and the right side plate are leveled. Such a design can ensure the perpendicularity after installation.

[0014] Beneficial effects of adopting the present invention:

[0015] Adopting the structure of the present invention, the riveting method has a compact structure. There is no need to bend the flange edge on the side plate to support the connection hole. After riveting, there is no redundant sheet metal material inside the product, which improves the space utilization rate and integration degree of the product;

[0016] The riveting method of the present invention has a simple structure. The partition plate does not need to be bent, which can save materials and the bending process, and effectively reduce the product cost;

[0017] The riveting method of the present invention is tightly and self-positioningly matched through the riveting terminal and the square hole. Without using a tooling fixture, the assembly accuracy can reach ±0.05, which improves the accuracy of the product itself and effectively avoids the generation of cumulative errors;

[0018] The riveting method of the present invention does not use screws for installation, avoiding the risk of thread damage;

[0019] After being crimped, the appearance of the riveting method of the present invention is flat, without defects such as protrusions and deformations, making the product beautiful and generous. It is a new technology worthy of popularization. Description of the drawings
