Embodiment Construction
[0028] The present invention will be further described below with reference to the accompanying drawings.
[0029] like figure 1 , figure 2 As shown, the aero-engine pipeline assembly positioning device of the present invention includes a post-process casing 1 that can be placed on the mounting edge 2 of the rear casing of the combustion chamber, and the bottom of the post-process casing 1 is installed with the rear casing of the combustion chamber The sides 2 are matched, and the side of the post-process casing 1 is provided with air bleed pipe joints 3. The number and assembly positions of the bleed pipe joints 3 are the same as those of the aero-engine turbine rear casing bleed joints.
[0030] The post-process casing 1 is used to replace the original rear casing of the turbine to realize the assembly and positioning of the secondary bleed pipe 5, which can reduce the process of sub-assembling the rear casing of the turbine, thereby reducing the failure rate of the five-p...

The invention discloses an aeroengine pipeline assembly positioning device and an assembly method in the technical field of aeroengine maintenance. The assembling and positioning device comprises a process rear casing that can be placed on the installation edge of the combustion chamber rear casing, the bottom of the process rear casing matches the combustion chamber rear casing installation edge, and the side of the process rear casing is provided with a guide The trachea joint, the assembling position of the bleed air pipe joint is the same as the assembling position of the bleed air joint of the aero-engine turbine rear casing. During assembly, the internal and external culvert pipeline assembly process is pre-installed at the core machine assembly stage, and the post-process casing is used to replace the turbine post-casing to realize the positioning of the secondary air induction pipe. After the secondary air induction pipe is installed, the post-process machine is removed Cassette, which can reduce the process of sub-packing the turbine casing, which not only improves the assembly efficiency, but also reduces the failure rate of the five fulcrum bearings and graphite components. At the same time, there is no interference with the assembly frame after the pre-process, which is convenient for operation and avoids Risk of falling from working at heights.
Description
technical field [0001] The invention relates to the technical field of aero-engine maintenance, in particular to an aero-engine pipeline assembly positioning device and an assembly method. Background technique [0002] Aero-engine assembly is an important part of aero-engine maintenance. The assembly process of a certain type of aero-engine mainly includes: assembling the core engine → reversing → assembling the fan unit body → assembling the internal and external pipelines → assembling the low-turbine components → completing the assembly. In the process of assembling the secondary bleed pipe, generally first tighten the connecting nut between the secondary bleed pipe and the front casing of the high-pressure compressor, and then pretend to be the rear casing of the turbine, adjust the installation position of the secondary bleed pipe, and align the rear joint of the secondary bleed pipe. Connect the secondary bleed pipe to the rear casing of the turbine, tighten the connec...
