Description

Tensioning device and profile frame for fairing butt joint Technical Field The utility model relates to the technical field of fairing closing, in particular to a tensioning device and a mold frame for fairing butt joint. Background Fairings are protective enclosures designed for aircraft (e.g., satellites, etc.), as the name implies, "fairing" refers to directing airflow to smooth motion by optimizing aerodynamic profiles, while "cowling" emphasizes its wrapped protective properties. When the aircraft breaks through the atmosphere or runs at high speed, the streamline surface of the fairing can convert the oncoming air resistance into laminar flow, so that the accurate control of the flight track is ensured. Meanwhile, the firm shell of the fairing forms a protection system, so that potential threats such as space debris can be intercepted, and a safe and stable working environment is provided for precise instruments in the aircraft. The cowling is usually two half cowling halves when produced, and requires subsequent cowling (butt joint) operations by means of a jig. When the cowling is covered, the half cowlings of the two cowlings are respectively placed into the two mold frames, and the cowlings are covered by combining the mold frames. Generally, in the process of covering, the fairing needs to be horizontally placed in the mold frame, and the covering work of the fairing is performed by adopting a horizontal covering mode (namely, two mold frames are horizontally butted). When a large-diameter fairing (for example, a satellite fairing) is covered, the large-diameter fairing is generally limited by a larger size, and a vertical covering mode is adopted, namely, after two fairing halves are respectively placed in two mold frames, the mold frames need to be vertically hoisted to carry out the covering work of the fairing. When two mold frames are butted (namely, after the cowlings are butted in the mold frames), if the butted joint of the two mold frames is not firmly tensioned, namely, the butted joint of the half covers of the two cowlings is not firmly tensioned, then when the butted joint of the half covers of the two cowlings after subsequent butt joint is welded (namely, when the half covers of the two cowlings after the butt joint are welded into a whole), gaps are formed between the half covers of the two cowlings which are not tensioned, and further, the welding work of the half covers of the two cowlings cannot be smoothly carried out. Therefore, there is a need for a device that can firmly tighten the two mold frames after the cowling is abutted, that is, a device that can firmly tighten the abutted portions of the half covers of the two cowling, so that the welding operation of the half covers of the two cowling can be smoothly performed.
