Machining tool and machining method for adjusting piece of aero-engine

Abstract

The invention provides an aero-engine adjusting sheet machining tool and method, and relates to the technical field of machining. The machining tool comprises a clamp body (1), a pressing block (2), a taper positioning pin (3) and a cylindrical positioning pin (4), and a plurality of screw holes and a plurality of pin holes are formed in the center of the clamp body (1); the cylindrical positioning pin (4) is arranged in the pin hole; the pressing block (2) is arranged in the middle of the clamp body (1). The taper positioning pin (3) penetrates through the pressing block (2) and the clamping plate (102) at the same time. By means of the machining tool, the problems that machining procedures of the aviation adjusting piece are scattered, clamping is difficult, and machining efficiency is low are solved. The machining method is convenient to operate, the machining precision can be effectively improved, and the product machining quality is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing tool and a processing method for an aero-engine regulating plate. Background technique [0002] The engine regulating plate is a key component of the tail injection system of the aero-engine. It is subjected to high temperature and high pressure flame injection during operation and is used to adjust the area of ​​the engine nozzle. [0003] like Figure 4-6 As shown, the engine trim includes a cast surface that is not machined and a surface that needs to be machined. The elements that need to be processed on the workpiece are divided into multiple orientations. According to the traditional method, multiple clampings are required to complete the processing. That is, for the first clamping, the upper half of the cylinder 513, groove one 501, groove two 502, groove four 504, cone surface one 505, cone surface two 506, side one 507, side two 508, and hole ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the technical problems of existing processing methods, such as process dispersion, accumulation of clamping errors, and difficult clamping caused by the part reference plane being a casting surface, the present invention provides an aero-engine trim piece processing tool and a processing method to achieve centralized process and reduce assembly. The purpose of reducing the clamping error and improving the clamping efficiency, so that all parts of the product to be processed can be processed in one clamping
