The utility model fully utilizes the principle of the moment rod to convert the moment of the oversized round nut into the moment from the center of the cover plate to the bolt. The utility model has simple structure, easy assembly and disassembly, convenient use and wide application.
Description
Technical Field
The utility model relates to an assembly technology, in particular to an installation tool for a threaded ring with a flange hole on a helicopter.
Background
At present, a threaded ring on a helicopter is usually provided with an internal thread, the threaded ring needs to be screwed with an external thread cylinder, and a common tool cannot be matched with the threaded ring due to the fact that the size of the threaded ring is usually large, but because the assembly screwing is a necessary step, an installation screwing tool is needed to assist in installation, torque conversion is carried out through a force arm, and screwing of the oversized circular threaded ring on the helicopter is achieved by using the common tool.
Disclosure of Invention
The purpose of the utility model is that: the mounting and screwing tool for the threaded ring on the helicopter, in particular to a mounting and screwing tool for the threaded ring with the flange hole in the oversized size and a using method of the mounting and screwing tool for the threaded ring with the flange hole on the helicopter are provided.
The technical scheme of the utility model is as follows: the mounting tool with the flange hole threaded ring comprises a cover plate 1, a bolt 2 and a torque wrench, wherein a plurality of through holes are formed in the cover plate, the through holes correspond to end face holes of the threaded ring, and the bolt 2 can pass through the through holes to be inserted into the end face holes of the threaded ring, so that the cover plate 1 and the threaded ring can integrally rotate;
the rear end of the torque wrench is a holding part, the front end of the torque wrench is a force application part, and a square boss is formed at the front end of the torque wrench;
a square hole is formed in the center of the cover plate 1 and matched with the square boss in shape; and the torque wrench is twisted, and the cover plate 1 can be driven to rotate along with the torque wrench through the square boss.
Further, the cover plate 1 is provided with a downward flanging to form a downward circular groove, so that the threaded ring can be embedded into the circular groove.
Further, the plug pin 2 is a step shaft.
Further, a flange is formed at the rear end of the bolt 2, and the outer diameter of the flange is larger than the aperture of the through hole of the cover plate.
Further, the through hole is a step hole. The bolts with different diameters can be matched.
Further, the square hole is a step square hole. Square bosses of at least two dimensions can be matched.
The using method comprises the following steps:
the bolt prize cover plate and the threaded ring with the flange hole are installed into an integral rotating mechanism, the square boss of the torque wrench is inserted into the square hole, and the torque wrench is rotated to complete the rotating screwing of the threaded ring.
The utility model has the beneficial effects that: the utility model fully utilizes the principle of the moment rod to convert the moment of the oversized round nut into the moment from the center of the cover plate to the bolt. The utility model has simple structure, easy assembly and disassembly, convenient use and wide application.
