Abstract

The invention provides a disassembling device and method for a double-tightness chuck. The disassembling device comprises a lifting mechanism, a body, a rotating mechanism, an outer ring lifting mechanism, a base plate and a grabbing mechanism. The body is arranged below the lifting mechanism, the grabbing mechanism is arranged below the body, and the body, the lifting mechanism and the grabbing mechanism are fixedly connected. The outer ring lifting mechanism is mounted at one end of the grabbing mechanism in a sleeving mode and connected with the body, and the other end of the grabbing mechanism makes contact with a chuck body in the to-be-separated double-tightness chuck. The base plate is arranged below the outer ring lifting mechanism. A turbine disc in the to-be-separated double-tightness chuck is placed in a cavity between the base plate and the outer ring lifting mechanism and fixed to the base plate. The rotating mechanism is arranged on the upper surface of the outer ring lifting mechanism. According to the disassembling device and method for the double-tightness chuck, the chuck pre-deforms through a disassembling hydraulic device, the synchronous double-tightness over-positioning chuck is disassembled in steps, friction and interference between parts during relative motion decomposing are eliminated, and the disassembling process is stable, accurate, reliable, and free of bumping.

Description

technical field [0001] The invention belongs to the technical field of aero-engine assembly, and in particular relates to a method for disassembling a double-tightness chuck. Background technique [0002] In recent years, the chuck (i.e. the integrated structure of the front sealing plate of the turbine rotor and the baffle) has been widely used in domestic advanced aero-engine research products. It is not only the axial positioning baffle of the turbine blade but also the Rotating non-contact gas sealing device, this structure simplifies the turbine components, reduces the number of parts, weight and improves the cooling effect of the disc, which has significant advantages in improving the performance of aircraft engines. [0003] From the analysis of the assembly structure of the chuck and the turbine disk, the chuck and the turbine disk are connected in a "pressure cooker cover" type, and the axial fit tightness is 1.07-1.31mm (that is, the amount of deformation of the ch...
