Low-pressure turbine butt-joint assembling device capable of preventing balls from falling off

Abstract

The invention discloses a low-pressure turbine butt-joint assembly device capable of preventing balls from falling off, and belongs to the technical field of automatic assembly. The low-pressure turbine butt-joint assembly device is characterized by comprising an aluminum base, a push rod and a guide shaft, a second V-shaped block is fixedly connected to the top of the aluminum base, and a simulation fan is fixedly connected to the inner wall of the second V-shaped block. A bearing inner ring is assembled at the tail of a low-pressure turbine shaft of an engine, a bearing outer ring is assembled at the end of a fan of the engine, a centering mechanism is assembled on a clamping tool for clamping the low-pressure turbine shaft, and the centering mechanism assists the bearing inner ring on the low-pressure turbine shaft to be matched with the bearing outer ring on the fan. The butt joint of the low-pressure turbine shaft and the fan is converted into the butt joint of the bearing inner ring and the bearing outer ring, the assembly centering precision of the low-pressure turbine shaft and the fan is greatly improved, the mode is automatic in assembly, the needed time is short, the production efficiency is high, the assembly consistency of components is good, and the centering precision is high.

Description

Technical field[0001]The present invention relates to the field of automated assembly technology, and more particularly to a low pressure turbocouple assembly device for preventing ball falling.Background technique[0002]In the aerospace engine, the low pressure turbine shaft is connected to the low pressure turbine unit end of the low pressure turbine unit, and the power transmission of the low pressure turbine rotor is realized, and the bearing is high, and the bearing assembly is high. Ten tons of axial force and tens of thousands of macaron drive torque, and its connection part belongs to the critical position of the cross-section mutation, so the assembly performance of the shaft assembly is an important factor in the operational reliability of the engine.[0003]The long-scale low-voltage turbine axis of the aviation engine transmits the torque of the low-pressure turbine rotor to the fan rotor and operates to ensure the normal operation of the air turbofan engine, during the low...

Problems solved by technology

[0003] The long-sized low-pressure turbine shaft of the aero-engine transmits the torque of the low-pressure turbine rotor to the fan rotor and drives the fan to work, so as to ensure the normal operation of the aero-turbine fan engine. During the docking and assembly process of the low-pressure turbine shaft and the fan, at present, it mainly relies on the experience of workers to repeat Trial assembly and calibration lead to poor component assembly consistency and low centering accuracy. Therefore, those skilled in the art provide a low-pressure turbine butt joint assembly device that prevents balls from falling to solve the problems raised in the above-mentioned background technology
