Mounting and positioning device for repairing segmented long hinge of helicopter

Abstract

The invention belongs to the field of helicopter process equipment design, and particularly relates to a mounting and positioning device for repairing a segmented long hinge of a helicopter. The device takes an L-shaped positioning slide rail as a main body, a plurality of left positioning slide blocks and right positioning slide blocks are arranged on the L-shaped positioning slide rail, and each positioning slide block can position one hinge tooth of a hinge; the left positioning sliding blocks and the right positioning sliding blocks are combined in pairs, so that one hinge is positioned; the hinge teeth of each section of hinge are respectively positioned through the combination of a plurality of groups of left and right positioning sliding blocks, and one group of left and right positioning sliding blocks is selected for a newly added hinge to realize positioning; and all the hinges are ensured to be positioned on the same axis after replacement.

Description

technical field [0001] The invention belongs to the field of helicopter process equipment design, and in particular relates to an installation and positioning device for repairing segmented long hinges of helicopters. Background technique [0002] On the transmission platform of a helicopter, due to the strength of the hinge and the limitation of processing, a multi-segment series distributed long hinge structure is usually adopted; one of the long hinges is riveted on the transmission platform, and the other is usually set on the movable cover. After the shafts are docked, the same cleaning bar is used to connect the movable cover; after long-term use, some hinge teeth may be damaged, and partial hinge teeth or the entire hinge need to be repaired; the repaired hinge still needs to meet The assembly position requirements of the original hinge; in order to ensure that the repaired hinge meets the use requirements, a corresponding hinge positioning device is required to ensur...

Problems solved by technology

[0002] On the transmission platform of a helicopter, due to the strength of the hinge and the limitation of processing, a multi-segment series distributed long hinge structure is usually used; one of the long hinges is riveted on the transmission platform, and the other is usually set on the movable cover. After the shafts are docked, the same cleaning rod is used to connect the movable cover; after long-term use, some hinge teeth may be damaged, and partial hinge teeth or the entire hinge need to be repaired; the repaired hinge still needs to meet The assembly position requirements of the original hinge; in order to ensure that the repaired hinge meets the use requirements, a corresponding hinge positioning device is required to ensure the position of each hinge and the coaxiality of the hinge teeth; the conventional repair method currently used is to use The hinge cleaner of the original hinge can position multiple hinges. However, the length of the hinge on the helicopter is often longer. During the repair operation, it is inconvenient to insert the hinge cleaner, the repair efficiency is low, and the rigidity of the cleaner is poor. , especially the slender cleaning rods are easily deformed, and the position requirements of the repaired hinges cannot be guaranteed

At the same time, the helicopter transmission platform is also equipped with many auxiliary structures, and the operating space for hinge repair is limited. In order to avoid other auxiliary installation structures during repair, multiple people are required to cooperate and cooperate with external auxiliary mechanisms to complete the joint operation. Repair of hinges and hinge teeth; generally speaking, the repair efficiency is low, the operation is difficult, and the repair accuracy is not high by conventional repair methods
