Problems solved by technology

The elastic deformation of the baffle must be within a certain range during the assembly process. If it is too large, it will easily cause damage to the baffle, and if it is too small, the snap ring cannot be ejected.

Abstract

The invention belongs to the technical field of aero-engine assembly, particularly relates to an installation device for a clamping ring type connecting baffle. The installation device comprises a base, a positioning ring, supports, pressing plates and dial gauge stands; the base is disc-shaped, and the positioning ring is fixedly arranged on the base; the dial gauge stands each comprise a dial gauge head joint, a dial gauge rod and a supporting column, wherein the supporting columns are fixed on the base, the dial gauge head joints are fixed on the supporting columns, the dial gauge rods areconnected with the dial gauge head joints, and dial gauges are installed on the dial gauge head joints; the supports are fixed on the base; the pressing plates are arranged on the supports, wherein adjusting supports are arranged at one ends of the pressing plates and are parallel with bolts, the adjusting supports are fixed to the pressing plates through nuts, and the pressing plates are evenly distributed on the base; and the pressing plates and the dial gauge stands are arranged on the outer side of the positioning ring at intervals, and between every two pressing plates is provide with a dial gauge stand. According to the installation device, the clamping ring type bolt-free connecting baffle can be assembled and disassembled.

Description

technical field [0001] The invention belongs to the technical field of aero-engine assembly, and in particular relates to an installation device and an installation method of a clasp-ring type connection baffle. Background technique [0002] The main function of the baffle is to realize the axial positioning of the turbine blades. On early aero engines, this function was performed by simple locking plates. The connection between the front and rear baffles and the turbine disc is usually bolted. From the structural point of view, this connection is simple and reliable, but the bolt holes must be processed on the turbine disc and the baffle, which reduces the related low-cycle fatigue. life, and the "stirring" effect of the bolt head at high RPM has a negative impact on the air system. Therefore, no holes or less holes are opened on the turbine disk, and the connection form without bolt fastening-boltless connection came into being. There are two structural forms of the baf...
