Fixing fixture for cleaning turbine blade and operation method thereof

Abstract

The invention relates to a fixing fixture for cleaning a turbine blade and an operation method thereof. The fixing fixture for cleaning the turbine blade comprises a support assembly, an upper fixingassembly and a lower fixing assembly. The support assembly comprises a base and a support frame. The upper fixing assembly comprises a fixing rod, two support rods and two manipulators. The lower fixing assembly comprises an assembly piece a and an assembly piece b. The upper fixing assembly adopts two manipulators, and two sides of the turbine blade are fixed by the two manipulators. The arc of the manipulators are consistent with the arc of the turbine blade, and the manipulators are ensured to be in close contact with the turbine blade, so that the manipulators clamp the turbine blade morefirmly. Recessed parts of the assembly piece a and the assembly piece b of the lower fixing assembly can fix different types of turbine blade tenons. The recessed part of the assembly piece a is matched with a groove a or the recessed part of the assembly piece a is matched with a groove c to double limit the turbine blade, so that the turbine blade is fixed more firmly, and a fixing table can beselected according to the length of the turbine blade to be cleaned.

Description

technical field [0001] The invention belongs to the technical field of turbine blades of aviation generators, and in particular relates to a fixing fixture for cleaning turbine blades and an operation method thereof. Background technique [0002] At present, the rough castings of aero-engine turbine blades that have just been processed have a large amount of attachments on the surface due to the processing process. Usually, the strong impact of high-pressure jet water is required to remove the attachments on the surface. However, some types of turbine blades The shape of the tenon of the blade is very irregular, and it is difficult to fix it when clamping. Therefore, there is an urgent need for a cleaning fixture that can not only meet the clamping and fixing of the irregular shape of the tenon, but also withstand the impact of high-pressure jet water. Contents of the invention [0003] The technical solution adopted by the present invention to solve the technical problem ...
