Abstract

A disassembly device and method for a double-tightness chuck provided by the present invention includes a lifting mechanism, a body, a rotating mechanism, an outer ring lifting mechanism, a backing plate and a gripping mechanism, wherein the body is arranged below the lifting mechanism, and the gripping mechanism is placed It is under the body, and the three are fixedly connected; the outer ring lifting mechanism is set on one end of the grasping mechanism and connected to the body, and the other end of the grasping mechanism is in contact with the chuck in the double-tightness chuck to be separated; the backing plate is placed Below the lifting mechanism of the outer ring, the turbine disk in the double-tightness chuck to be separated is placed in the cavity between the backing plate and the lifting mechanism of the outer ring, and fixed on the backing plate; the rotating mechanism is set on the lifting mechanism of the outer ring The upper surface of the upper surface; the present invention uses the decomposing hydraulic device to make the chuck pre-deformed, and decomposes the synchronous double-tight over-positioning chuck step by step, eliminating the friction and interference between the parts during the relative motion of the decomposition, and the decomposing process is stable and accurate , Reliable, no bump damage.

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...
