Abstract

The invention discloses a turbine blade assembling insurance clamp and a method for performing impeller clamping thereof, which belong to the technical field of aircraft engine gas turbine blade assembling. Bosses are evenly distributed on the edge portion of an air inlet edge positioning seat of a turbine disc of the turbine blade assembling insurance clamp, a screw penetrates through the air inlet edge positioning seat of the turbine disc to be fixed with an air discharging edge positioning seat of the turbine disc, and in use, turbine blades are fixed. The method for performing impeller clamping includes the following steps: step 1 assembling the air inlet edge positioning seat and an impeller; step 2 installing the impeller in an air inlet edge positioning seat assembly; step 3 installing a gasket; and step 4 installing an air discharging edge positioning seat assembly. The turbine blade assembling insurance clamp leads insured blades to meet requirements for dimensions of 3.4+ / -0.5mm, avoids the blades from being ejected to be loose and improves turbine blade assembling yield rate. The method for performing blade clamping can perform turbine positioning fast and conveniently and reduces labor intensity and maintenance cost.

Description

technical field [0001] The invention relates to an assembly technology of an aero-engine gas turbine blade, in particular to an assembly technology in which a turbine disk and blades are connected by locking pieces. Background technique [0002] The turbine disk and blades connected by the locking plate, the acceptance criteria for the assembly of the turbine blades are: no looseness is allowed after the blades are secured, and the boss on the leading edge of the blade is 3.4±0.05mm higher than the end surface of the turbine disk inlet side. In the process of assembling the insurance of the engine turbine blades, due to the design defects of the original assembly tooling, the blades that have been insured are often loosened by the tooling, making the blades loose, and cannot meet the size requirement of 3.4±0.05mm. Therefore, it is necessary to remove and discard the lock plate, and to insure the blades again so that all the blades on the entire turbine disk meet the size re...
