A method for automatic nozzle deburring and flow adjustment

Abstract

An automatic nozzle deburring and flow adjusting method comprises the steps that the initial flow value of a main / auxiliary oil spraying port of each nozzle is measured; grinding particle flow equipment is utilized for machining a main / auxiliary oil path of each nozzle, and burrs on each main / auxiliary oil path are removed; cleaning fluid is utilized for cleaning the main / auxiliary oil path of each nozzle; the cleaning fluid is utilized for cleaning the grinding particle flow equipment; the nozzle flow after machining is detected and then compared with the initial flow value, and the grindingparticle flow machining time and flow changing relation under corresponding machining parameters is determined; for nozzles with small flow, secondary grinding particle flow machining is conducted onthe nozzles according to the obtained grinding particle flow machining time and flow changing relation, the nozzle flow is further adjusted till the flow of all the nozzles is consistent, and the flowrequirement is met; the grinding particle flow equipment is cleaned; ultrasonic cleaning equipment is utilized for nozzle cleaning, and residual cleaning fluid is removed; and the weight of each nozzle is measured and compared with the initial weight of the nozzle before grinding particle flow machining, and it is ensured that the nozzle weight changing value does not exceed 50 g.

Description

technical field [0001] The invention belongs to the technical field of aero-engine component manufacturing, in particular to an automatic nozzle deburring and flow regulating method. Background technique [0002] The fuel nozzle of an aero-engine is a key component for propelling fuel combustion, which has an important impact on the fuel efficiency and power performance of an aero-engine. The internal structure of the fuel nozzle is complex and there are many parts. It is necessary to precisely control the dimensional accuracy of each part inside the nozzle to accurately control the flow of fuel and improve combustion efficiency. [0003] At present, the fuel nozzle of an aero-engine is assembled from nearly 10 parts, and there are two main and auxiliary oil passages on the nozzle.

Problems solved by technology

[0003] At present, the fuel nozzle of an aero-engine is assembled from nearly 10 parts, and there are two main and auxiliary oil passages on the nozzle. At this stage, the burrs on the nozzle oil passage are usually removed manually, but for the inner hole and internal intersection on the nozzle oil passage There is no good way to remove the burrs at the holes. If the burrs at the inner holes and inner cross holes on the nozzle oil road cannot be completely removed, it will directly affect the flow stability and the safety of the aero-engine.

At the same time, due to the strict requirements on the outlet flow of the nozzle, it is necessary to adjust the flow of the nozzle. The current method can only be disassembled first, and then the size of the individual parts is adjusted separately, and finally the flow can be adjusted. However, the above flow adjustment methods are not only inefficient, but also poor in consistency
