Embodiment

[0031] The large-scale gas turbine multi-connector vane targeted by this embodiment is such as figure 1 and Figure 7 As shown, the large gas turbine multi-connector blade is mainly composed of a blade body and a large edge plate and a small edge plate located on both sides of the blade body. The blade has 12 parts A to L to be processed surfaces.

[0032] The tooling provided in this embodiment for processing multi-connector blades of large gas turbines, such as 2 to Figure 5 , Figure 8 As shown, it includes a tooling seat 13 and a positioning support mechanism and a pressing mechanism provided on the upper seat plate of the tooling seat. The positioning support mechanism includes a fixed positioning support mechanism and an auxiliary positioning support mechanism; the pressing mechanism includes a blade body pressing mechanism and a small end edge plate auxiliary pressing mechanism.

[0033] Such as image 3 The tooling seat 13 shown is composed of an upper seat plate, a lower ...

Abstract

The invention discloses a tool for machining multiple guider blades of a large gas turbine. The tool comprises a tool base, and a positioning support mechanism and a pressing mechanism arranged on thetool base; the positioning support mechanism comprises a fixed positioning support mechanism and an auxiliary positioning support mechanism; and the pressing mechanism comprises a blade body pressingmechanism and a small end flange plate auxiliary pressing mechanism. Through cooperation between each support mechanism and the pressing mechanism, the quick installation and positioning of multiplexguider blade parts of the large gas turbine can be realized; the positioning stability of the machined parts is improved; the bruise of the parts is effectively prevented; and the machining quality of the parts is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of aero engine manufacturing, and relates to a large gas turbine guide blade processing technology, in particular a large gas turbine multi-connected guide blade processing tool that requires six-point positioning to realize reference arc surface processing. Background technique [0002] Gas turbine is an important product in the field of large gas turbines, and the blade is the heart of the gas turbine, so the processing quality of the blade is related to the normal operation and service life of the entire gas turbine. As we all know, blade processing is one of the most difficult processes in gas turbine manufacturing, especially for special-shaped parts such as large multi-connector blades. Because the material used is nickel-based high-temperature compliance material PWA 1498, the processing performance is extremely poor, and additional In the process, the reference plane is positioned; especially when milling...
