The invention provides a connecting device for an aircraft actuator cylinder support and an oil tank structure, which comprises an oil tank, a bowl-shaped actuator cylinder support, an oil tank partition plate, a bolt and a nut, a groove is formed in one side of the oil tank, the oil tank partition plate is connected with the oil tank, and a convex connecting rib is arranged in the middle of the oil tank partition plate. The bowl-shaped actuator cylinder support is provided with a plurality of bolt holes, bolts penetrate through the bolt holes in the bowl-shaped actuator cylinder support and the bolt holes in the connecting ribs of the oil tank partition plate to connect the bowl-shaped actuator cylinder support with the oil tank partition plate, the nuts and the bolts are matched and screwed to connect and fix the bowl-shaped actuator cylinder support with the oil tank partition plate, and the bolts and the nuts are connecting pieces. The connecting direction is designed to be the wingspan direction of the aircraft and is not in contact with fuel oil in the oil tank, and the bowl-shaped actuator cylinder support is not in contact with the fuel oil in the oil tank. Potential safety hazards caused by direct contact between the bolt and the nut and fuel oil in the oil tank are avoided, the installation space is open, if the bolt and the nut are damaged, maintenance and replacement of the connecting piece can be completed in time in the open space, and good maintainability is achieved.
本发明提供一种飞机作动筒支座与油箱结构的连接装置,包括油箱、碗形作动筒支座、油箱隔板、螺栓、螺母,油箱一侧设有凹槽,油箱隔板与油箱连接,油箱隔板中间设有凸起连接筋,碗形作动筒支座设有多个螺栓孔并通过螺栓穿过碗形作动筒支座上的螺栓孔和油箱隔板连接筋上的螺栓孔将碗形作动筒支座与油箱隔板连接,螺母与螺栓配合扭紧将碗形作动筒支座与油箱隔板连接固定,其中螺栓和螺母为连接件,连接方向设计为飞机翼展方向且不与油箱内燃油接触,碗形作动筒支座不与油箱内燃油接触。本发明避免螺栓和螺母直接与油箱内燃油的直接接触所带来的安全隐患,且安装空间开敞,若螺栓和螺母发生损伤破坏,可在开敞空间内及时完成连接件的维护更换,具有良好的可维护性。
