Combination machining device for gas compressor stator component assembling

Abstract

The invention discloses a combination machining device for gas compressor stator component assembling. A positioning platform and a spigot clamp are arranged; the positioning platform is attached to and fixedly connected with the front mounting edge end face of a gas compressor stator component to be subjected to assembling and combination machining; the spigot clamp is used for jointly clamping arear component and an inner component of the gas compressor stator component to be subjected to assembling and combination machining, thereby preventing a rear end spigot of the gas compressor statorcomponent from deforming; simultaneously, the positioning platform and the spigot clamp are respectively matched with the front mounting edge of the engine compressor stator component and the rear mounting edge of the engine compressor stator component, thereby realizing the requirements of one-time assembling and clamping of the gas compressor stator component for multiple different combinationmachining and detection as well as meeting the situation of ensuring the precision due to the process adjustment machining caused by production resource problems; the detection and combination machining of the front and rear end surfaces of the gas compressor stator component and an inner ring of a rectifier can be achieved; and meanwhile, the two benchmarks of the front mounting edge end face andthe front mounting edge pitch circle of the gas compressor stator component to be subjected to assembling and combination machining can be ensured to be unchanged in the processes of assembling, transferring, combination machining and detecting, and repeated assembling and disassembling of the gas compressor stator component is reduced.

Description

technical field [0001] The invention belongs to the technical field of assembling an engine compressor assembly, and in particular relates to a combined processing device for assembling an air compressor stator assembly. Background technique [0002] As a simulated assembly of the engine, the compressor stator assembly consists of a front-to-side open case, a center-to-open case, an inner casing, a rear casing, multi-stage guide vanes, multi-stage rectifiers and inner rings at various levels. According to the design requirements, the purpose of the first assembly of the compressor stator assembly is: combined grinding of honeycombs on the inner rings at all levels; combined inspection of the adjustable angle range of the guide vanes at all levels, and clamping and polishing; combined processing to ensure the overall axial length of the components and end face runout; check and process to ensure the distance from the front and rear end faces of the inner rings at all levels t...

Problems solved by technology

[0003] In order to ensure the above design requirements, the compressor stator assembly needs to be assembled in a simulation according to the installed state. After assembly, it needs to be combined with the transfer case center and the research and development center for combined processing, and the transfer metering center for testing. The compressor stator assembly weighs about 90 kg. The large thin-walled easily deformable part with a total length of about 500mm and a diameter of about φ800mm, after repeated hoisting and transportation, its front and rear mounting edges are more likely to be bumped, damaged and deformed, resulting in difficulties in aligning benchmarks and processing deviations during combined processing and testing, and cannot guarantee processing quality and The final assembly quality of the whole machine increases the difficulty of processing and assembly. At present, it mainly relies on human control of the hoisting process, but it is still unable to ensure the safety of the hoisting process.
