Splicing equipment for gas turbine engine assembly

Abstract

The invention belongs to the technical field of aero-engine manufacturing, and in particular relates to a splicing device for assembling a gas turbine engine, which includes a base on which a guide ring is arranged; The second expansion part attached to the outer ring surface, the inner support ring and the outer support ring form a detachable connection with the base; it also includes a pressure ring configured to open and close with the guide ring along the axial direction of the guide ring. During the splicing process, the connecting components are first placed on the guide ring one by one, the pressure ring presses each connecting component tightly, and the pressure ring continues to press down, so that the first arc-shaped wall and the second arc-shaped wall of the connecting component slide to the On the inner support ring and the outer support ring, the pre-installed positioning between the connecting components is realized, which provides convenience for the subsequent assembly between the connecting components and the central body.

Description

technical field [0001] The invention belongs to the technical field of aero-engine manufacturing, and in particular relates to a splicing device for assembling a gas turbine engine. Background technique [0002] The gas turbine engine is mainly used in the aerospace field. Its working principle is to use a compressor to pressurize the air, and the high-pressure air and fuel are mixed and ignited and then injected backwards to provide thrust; the tail of the gas turbine engine is generally equipped with a tail cone (also known as a center Body, center body), its role is to guide the tail airflow of the engine; in order to reduce the weight of the engine, the existing technology sometimes uses light ceramic materials to make the tail cone, and this presents a new technical problem, that is, how to ensure that the center body and the front end Reliable connection between structures.

[0002] The gas turbine engine is mainly used in the aerospace field. Its working principle is to use a compressor to pressurize the air, and the high-pressure air and fuel are mixed and ignited and then injected backwards to provide thrust; the tail of the gas turbine engine is generally equipped with a tail cone (also known as a center Body, center body), its role is to guide the tail airflow of the engine; in order to reduce the weight of the engine, the existing technology sometimes uses light ceramic materials to make the tail cone, and this presents a new technical problem, that is, how to ensure that the center body and the front end Reliable connection between structures. In order to solve this technical problem, the inventor of the present application has provided a metal connector at the front end of the ceramic central body. When installing, firstly connect the metal connector to the central body, and then connect the metal connector to the ceramic central body. However, there are many problems in the assembly process of the metal connector and the central body. For example, in order to avoid the internal stress generated when the metal connector is thermally expanded from affecting the strength of the ceramic structure, it is necessary to set the connector as a multi-stage structure and Expansion joints are set between adjacent connectors, and multi-section connectors are difficult to ensure assembly accuracy when assembling the ceramic center body, and the assembly process is easy to cause damage to the ceramic center body. In addition, it is necessary to ensure that the ceramic center body and the front end Smooth connection between structures to reduce air resistance, assembly tools in the prior art are difficult to meet process requirements
