Abstract

The invention relates to an overturning tool for RAT assembly, and belongs to the field of assembly tests. The tool is composed of an assembly mounting seat, a transfer seat, a rotating arm, a connecting rod, a base, a crank connecting rod, a thread adjusting rod and the like, so that a single-degree-of-freedom four-bar mechanism is formed. The thread adjusting rod is a driving part for overturning and has the functions of length adjustment and self locking, and a screw pair with the self-locking characteristic is designed. An RAT is assembled on the assembly mounting seat in a handstand mode,and the length of the thread adjusting rod is adjusted after assembly, so that the assembly mounting seat and the RAT product are overturned together until the RAT is erect. A crane interface is designed in the assembly mounting seat, so that the assembly mounting seat is connected with a crane, and after a connecting screw of the assembly mounting seat and the transfer seat is removed, the assembly mounting seat and the RAT product can be lifted together to a wind tunnel to conduct a test by using the crane.

Description

technical field [0001] The invention discloses a RAT assembling turning tool, which belongs to the field of assembling tests. Background technique [0002] RAT is an aircraft emergency energy device. It is mainly composed of turbines, actuators, gearboxes, support arms, frames, hydraulic pumps, generators and other components. The product structure is complex, large in size, heavy in weight, and difficult to assemble. Due to the structural characteristics of the product, it is easier to assemble in an inverted posture. After the product is assembled, it needs to be installed in the wind tunnel for performance test. At this time, the product should be in an upright posture. The current assembly test method is: assemble the RAT in an inverted posture on the fixed seat. After the assembly is completed, a number of test workers manually remove the RAT from the fixed seat, lift it to the wind tunnel, and then install the RAT mounting frame. , RAT product installation and other ...
