Embodiment

[0031] The large-scale gas turbine multi-connector guide vanes targeted by this embodiment are as follows: figure 1 and Figure 7 As shown, the multi-steering guide blade of the large gas turbine is mainly composed of the blade body and the large and small edge plates located on both sides of the blade body. There are 12 parts from A to L on the blade to be processed.

[0032] The tooling provided in this embodiment for processing multiple guide vanes 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 arranged 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 shown tooling seat 13 is composed of a...

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 the processing technology of guide blades of large gas turbines, in particular to the processing tooling for multiple guide blades of large gas turbines which requires six-point positioning to realize processing of reference arc surfaces. Background technique [0002] Gas turbines are important products in the field of large gas turbines, and blades are the heart of gas turbines. Therefore, the processing quality of blades 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 the manufacture of gas turbines, especially for special-shaped parts such as large multi-connector guide blades. Since the material used is nickel-based high-temperature composite material PWA 1498, the processing performance is extremely poor, and it needs to be added Position the reference pl...
