Technical Field

[0001] This utility model belongs to the field of riveting tool design technology, specifically relating to a riveting adapter for solid rivets. Background Technology

[0002] The primary connection method in aircraft structures is riveting, which uses rivets to connect two or more parts together. Solid rivet connections are widely used. When using solid rivets, force is applied to both the rivet head and rivet shank, forming a upset head on the rivet shank to secure the parts.

[0003] Traditional solid rivet riveting uses a combination of rivet gun sockets and baffle tools, or a combination of a riveting press machine and a riveting press head tool. Current rivet gun sockets need to be designed according to the product structure and rivet type. For the same structural form, different rivet types require different sockets, increasing tool manufacturing costs and warehouse management difficulties. Riveting press heads are generally in a box-like form, accommodating almost all rivet types. However, riveting press machines can only be used for specific structural forms, where the rivet position is open, the distance from the rivet hole to the product edge, and the rivet height cannot exceed the applicable range of the riveting press machine. On-site application of riveting press machines should not exceed 5% of the total riveting workload. Utility Model Content

[0017] 1. Rivet gun connector, 2. Stop ring, 3. Grip part, 31. Blind hole Detailed Implementation

[0018] like Figure 1 and Figure 2 The illustrated straight-body embodiment shows a solid rivet riveting adapter as a single unit. Functionally, it comprises a rivet gun connector 1, a stop ring 2, and a gripping part 3. The rivet gun connector 1 is connected to the pneumatic rivet gun (not shown) and moves under the thrust of the rivet gun during operation. The rivet gun connector 1 is on one side of the stop ring 2, and the gripping part 3 is on the other side. The gripping part 3 controls the depth of the riveting adapter within the rivet gun and stabilizes its working state during operation, preventing loosening or tilting. The gripping part 3 is a rod structure with a blind hole 31 at its outer end, which is connected to the riveting head (not shown). Its shape and length are designed according to the product's structural form.

[0019] Specifically, the rivet gun connector 1 is a cylinder with a chamfer at the end to facilitate connection with the pneumatic rivet gun. Its diameter matches the inner cavity of the pneumatic rivet gun with clearance fit, and its height is designed according to the working stroke of the pneumatic rivet gun.

[0020] The retaining ring 2 is an annular boss with a diameter larger than that of the rivet gun connector 1 and the same outer diameter as the working end of the pneumatic rivet gun. It is low in height and flat in shape, with an anti-detachment rubber sheet at one end and the other end attached to the pneumatic rivet gun to prevent loosening. Chamfers are provided at both ends of the retaining ring 2 to prevent damage to the product or injury to the operator during operation.

[0021] The gripping part 3 is cylindrical and serves as the working load-bearing part. Its diameter is slightly larger than that of the rivet gun connector 1 and slightly smaller than that of the stop ring 2. Its length is generally around 60mm. The working end has a chamfer, and its outer diameter matches that of the riveting head. The inner diameter of the blind hole 31 is adapted to the handle of the riveting head, and its depth is slightly higher than that of the handle of the riveting head, so that the working part of the riveting head is in direct contact with the gripping part 3 without any gap. The riveting head is equipped with an anti-loosening device, which automatically locks and will not loosen after being connected to the gripping part 3.

[0022] This straight-body riveting head adapter is suitable for open parts of products. The entire adapter is machined in one piece, providing good overall strength and high load-bearing capacity, preventing deformation and breakage during operation. For parts with limited space or closed angles, a different adapter can be selected. Figure 3 and Figure 4 The curved embodiment shown. The grip portion 3 can also be designed in various shapes depending on the product structure.

[0023] The rivet gun connector 1 and stop ring 2 of the curved riveting head are the same as those of the straight riveting head adapter. The gripping part 3 of the curved riveting head is a cylindrical curved body with an angle at the lower 1 / 3. The angle is designed to consider force transmission and strength, generally within 10°, and is the load-bearing part. Its diameter is slightly larger than the rivet gun connector 1 and slightly smaller than the stop ring 2. The end has a chamfer, and its outer diameter matches the outer diameter of the riveting head. The end face has a blind hole 31. This curved riveting head adapter is suitable for areas with limited space for rivets on products. The angle design meets working requirements and is not easily broken. The entire adapter is machined as a single piece, ensuring uniform force transmission and good rivet head forming effect.

[0024] When using solid rivets, select the appropriate shape of the holding part 3 according to the product structure where the solid rivet is located, and then select a suitable riveting adapter. Place the press riveting head into the blind hole 31 at the end of the holding part 3. The press riveting head has an anti-loosening design, so it will not loosen after being connected to the press riveting adapter. Connect the rivet gun connector 1 to the pneumatic rivet gun. Because the adapter tool and the pneumatic rivet gun are clearance fit, the depth is controlled by the stop ring 2. The riveting work is completed by the thrust of the reciprocating motion of the pneumatic rivet gun. The rivet gun connector 1 and the inner cavity of the pneumatic rivet gun are clearance fit and are fixed with an anti-loosening rubber sheet or by hand during operation. Place the press riveting head on the head of the solid rivet, and use a baffle to hold it at the end of the rivet shank. Through the force applied by the rivet gun, the force is transmitted to the rivet head through the adapter tool and the press riveting head, thereby causing the rivet shank to expand and upset, forming an upset head on the outside of the hole, which plays a role in connection and fixation. After using the adapter tool, for the same structure with rivets of different diameters and types, only the rivet head needs to be replaced, without the need to replace the adapter tool, which is convenient, quick and easy and highly applicable.

[0025] The aforementioned riveting head adapter tools are widely used, significantly reducing the types and quantities of rivet gun sockets to be manufactured. Both straight and curved adapter tools can meet most riveting needs. When used with a riveting head housing, they can be stored in a single box, are small in size, easy to carry, and quick to replace, reducing production and warehouse management costs. Adapter tools can also be custom-designed according to product shape and available space to meet all on-site usage requirements.
