A combined processing device for assembling stator components of a compressor

Abstract

The invention discloses a combined processing device for assembling a compressor stator assembly. By adopting a positioning platform and a seam clamp, the positioning platform is used to fit and fix the front mounting edge and end surface of the compressor stator assembly to be assembled and processed. The seam clamp clamps the rear assembly and the inner assembly of the compressor stator assembly to be assembled and combined to prevent deformation of the rear end seam of the compressor stator assembly. It is matched with the engine compressor stator assembly after installation, which realizes the requirement of one-time assembly, clamping and multiple different combined processing and inspection of the compressor stator assembly, and also satisfies the problem of process adjustment and processing to ensure accuracy due to production resource problems. Realize the detection and combined processing of the front and rear end faces of the compressor stator assembly and the inner ring of the rectifier, and at the same time ensure that the two benchmarks of the front mounting edge end face and the front mounting edge pitch circle of the compressor stator assembly to be assembled and combined processing are used in assembly, transfer, combined processing and There is no change in the detection process, reducing the multiple disassembly and assembly of the compressor stator assembly.

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.
