[0002] In the process of aircraft production and manufacturing, pallet nut fasteners are often used. Such fasteners are generally connected by two rivets during installation. The conventional method is to rivet the two rivets one by one by a riveter or a riveting clamp. When riveting rivets on planar parts, the parts and pallet nuts are relatively easy to fix, so the operation is relatively simple when riveting one by one. However, it is more cumbersome to install pallet nuts on curved parts. The curved parts and pallet nuts are not easy to fix, and the conventional method requires repeated adjustment of the attitude of the parts and pallet nuts during riveting, and ensures that the riveting process does not occur. The automatic riveting device is often limited by the processing range, such as the throat depth, and is only suitable for strip-shaped parts. In addition, the price of the device is often very high. Therefore, the conventional method requires a high level of skill and carefulness of the operator when riveting pallet nuts on curved parts, and quality problems such as rivet skewing and part damage are prone to occur. Therefore, rework may often occur during the installation process, delaying the production schedule, and there are other quality risks when disassembling and replacing.
