Problems solved by technology

[0007] For the assembly of blades in a narrow space, due to the small operating space and blind spots during installation, and the small size of the positioner, it is difficult to fix. If the traditional knocking method is used for installation, multiple people are required to complete the installation, which takes a long time and is difficult to operate. And there is a risk of damaging the rotor

Abstract

The invention provides a bending and locking device and method for a small positioner in a narrow space. The small positioner can be quickly and accurately locked and fixed in a limited space, and unnecessary mechanical damage is avoided while the assembly purpose is completed. The bending and locking device comprises a guide block and a locking bridge piece, and a guide groove communicating with the upper end and the front end is formed in the guide block; the locking bridge piece is rotatably arranged in the guide groove in the grooving direction, a locking bridge piece rotating inserting groove is formed in the driving end of the locking bridge piece, and a locking bridge piece locking plane is arranged at the working end of the locking bridge piece; and in the locking state, the locking bridge piece locking plane is parallel to the upper end of the guide block and is not lower than the upper end of the guide block.

Description

technical field [0001] The invention belongs to the field of assembly of aeroengine blades, and in particular relates to a bending locking device and method for a small positioner in a narrow space. Background technique [0002] Among the aeroengines, the number of blades is the largest, and the engine relies on numerous blades to complete the compression and expansion of the gas and generate powerful power with the highest efficiency to propel the aircraft forward. However, the blade is a special part, which has a large number, complex shape, high requirements, difficult processing, and is a part with frequent failures. Various types of blades need to be installed on the engine to actually work and be strong. [0003] At present, the blades are generally installed and locked in the following ways: [0004] 1) Use bendable sheet devices such as locking pieces and positioners to bend and lock; [0005] 2) The pin shaft is used to connect the wheel disc and the blade instal...
