Abstract

The invention provides a clamping device for an intermediate case supporting plate, the clamping device comprises a supporting structure, a pressing structure and a positioning structure which are located on a bottom plate, the supporting structure and the pressing structure are used for clamping the intermediate case supporting plate, and the positioning structure is used for positioning the intermediate case supporting plate when the supporting structure and the pressing structure clamp the intermediate case supporting plate. Blind holes are formed in the supporting structure and/or the positioning structure, auxiliary supporting assemblies are arranged in the blind holes, and the auxiliary supporting assemblies are used for conducting self-adaptive auxiliary supporting adjustment on the intermediate case supporting plate when the clamping device clamps the intermediate case supporting plate. The clamping device is high in practicability, high in production efficiency and good in machining quality, machining of the intermediate case supporting plate can be met, and the clamping device is particularly suitable for clamping and fixing the case supporting plate when the civil large-bypass-ratio intermediate case supporting plate is machined.

Description

technical field [0001] The invention belongs to the field of aero-engine blade processing, and relates to the processing technology of a casing support plate, in particular to a clamping device for an intermediate casing support plate. Background technique [0002] The aviation industry is compared to the crown of modern industry, and the aero-engine is also called the jewel in the crown of modern industry. It is the heart of the aircraft, and the processing quality of the aero-engine blades determines the performance level and service life of the engine. [0003] The intermediate casing support plate of the aero-engine is located between the outer casing and the intermediate casing, and is an important load-bearing component of the engine. The intermediate casing support plate is a titanium alloy hollow casting, which is bulky, complex in structure, and has edge plates at both ends. And the characteristics of high hole position and size requirements. When the intermediate ...
