Abstract

The invention belongs to the technical field of liquid-propellant rocket engine assembly. In the manufacturing process of a liquid-propellant rocket engine, engine assembly is one important working procedure which is ongoing in the end; and the assembly of an engine rotor relates to many pars, high quality requirement, heavy assembly work and high safety risk. The designs of a lifter, a clamp holder and adapter coupling pieces of an assembly trolley meet the fixed requirements of different sizes of rotors, and have certain universality. Meanwhile, the 360-degree rotation and position locking functions of the clamp holder are beneficial to the any-angle lifting and assembly of a rotor rotating shaft and an assembled unit body, so that the product safety can be ensured, and the operation is facilitated. The use of the assembly trolley is capable of reducing the labor intensity of a worker and improving the assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of liquid rocket engine assembly, and specifically relates to the technical field of assembly of a liquid rocket engine rotor unit composed of impellers, bearings, axial positioning components and shafts. Background technique [0002] In the manufacturing process of liquid rocket engines, engine assembly is the last important process. Among them, the assembly of the engine rotor involves many parts, high quality requirements, heavy assembly work, and high safety risks. [0003] The rotor of the liquid rocket engine is installed on the shaft in series by components of different structures and sizes such as impellers, bearings and positioning blocks. Generally, the vertical installation is convenient for operation. The operation method of the assembly workshop is to design a series of fixed The type tooling base is used to meet the assembly requirements of different types of rotors. The fixed tooling base occ...
