The device used for the pre-assembly of the aero-engine combustor flame tube

Abstract

The invention discloses a device for preassembly of a matching table of a flame tube of a combustor of an aero-engine. The components of the device comprise a base, a bearing shaft, a turntable, a dierectifying plate, a plug pin assembly, a cover plate, a first verifying pin and a second verifying pin. The bearing shaft is arranged in the center position of the base, the turntable is arranged outside the bearing shaft in a sleeved mode and rotatably arranged on the base and used for mounting a matching table component of a collector. The die verifying pin is fixedly arranged above the turntable, and the plug pin assembly is used for conducting angular positioning on the flame tube. The cover plate is mounted at the top end of the bearing shaft through a fastening piece and used for limiting and fastening a matching table component of the flame tube. The first verifying pin is used for verifying connection coordination of the matching component of the collector and the flame tube, andthe second verifying pin is used for verifying the coordination of the outer end of the flame tube. The device is adopted to conduct preassembly of the matching table of the flame tube of the combustor of the aero-engine, the assembly efficiency and the assembly continuity of the aero-engine and the coordination and the stability of the assembly position of the matching table can be improved greatly, the probability that engine components are damaged due to bumping or scratching can be lowered, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of aero-engine combustion chamber processing, and in particular relates to a device for pre-assembling a combustor flame cylinder matching platform during the assembly process of an aero-engine. Background technique [0002] The combustor flame tube matching platform is an aero-engine combustion unit assembled from flame tubes, collectors and other parts. It is the most important part of the aero-engine. Aeroengines are generally equipped with several combustor flame tubes, which are evenly distributed along the circumference of the engine case, and the flame tubes of each combustor flame tube are connected to each other by cross-fire tubes. The main part of the combustor flame tube matching platform is the flame tube and the collector. When the aero-engine is assembled, the flame tube and the collector are first assembled. Coordination must strictly meet the drawing design requirements, and then assemble a...

Problems solved by technology

In the actual assembly process of aero-engines, sometimes this disassembly process has to be repeated many times, which not only reduces the assembly efficiency and the continuity of the assembly process, but also easily scratches during the repeated disassembly and assembly of the flame tube or collector. Other parts of the engine and this part have a great impact on the product quality and the continuity of the engine assembly, and the operation is extremely inconvenient
