Embodiment Construction
[0039] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
[0040] like Figure 1-7 As shown, an aeroengine high-pressure rotor seal plate rear nut tightening device includes an indexing system 1 , a feed movement system 2 and a connecting rod tightening execution system 3 .
[0041] The indexing system 1 is fixedly installed on the rear shaft port of the high-pressure turbine rotor 6 through the flange 5 of the outer sleeve 4 .
[0042] The feed motion system 2 is located inside the indexing system 1, the middle sleeve 7 of the feed motion system 2 is connected with the outer sleeve 4 of the indexing system 1 through a bearing 8, and the indexing system 1 realizes the feed motion system 2 CNC rotation.
[0043] The link type tightening execution system 3 is located at the front end of the feed movement system 2, and the inner sleeve 9 of the link type tightening execution...
