Die assembling mechanism for turbine rotor with vibration attenuation plate, assembling mechanism and method

Abstract

The invention discloses a die assembling mechanism for a turbine rotor with a vibration attenuation plate, an assembling mechanism and a method. The die assembling mechanism for the turbine rotor with the vibration attenuation plate comprises a bottom die support for forming bottom support and an inner core support for forming radial support. The bottom die support and the inner core support are fixed and positioned in an embedded manner. A plurality of movable process mortise units which are used for enabling turbine rotor vane tenon teeth to be vertically inserted and assembled and move within a constraint range to assemble the vibration attenuation plate to the part between adjacent turbine rotor vanes. The multiple movable process mortise units are distributed in an adjoining manner in the circumferential direction of the inner core support, and the movable process mortise units and the turbine rotor vanes are distributed in a one-to-one corresponding manner. The circumferential dimensions of the movable process mortise units are matched with those of the turbine rotor vanes, and thus the assembled turbine rotor vanes are distributed in an adjoining manner in the circumferential direction of the inner core support. The overall transferring of a preassembled structure is facilitated, and the assembling efficiency of the turbine rotor is improved.

Description

technical field [0001] The invention relates to the technical field of aero-engine assembly, in particular to an upper mold mechanism for assembling a turbine rotor with damping plates. In addition, the present invention also relates to an assembly mechanism comprising the above-mentioned upper mold mechanism for assembling a turbine rotor with damping plates.
