A Blade Polishing CNC Machining Center with Ten Axes of Motion

Abstract

The invention provides a blade polishing numerical control machining center with ten movement shafts, and relates to the technical field of polishing numerical control. The blade polishing numerical control machining center comprises a blade polishing numerical control machining center lathe bed, a blade polishing numerical control machining center stand column, a blade polishing numerical controlmachining center X-axis movable sliding table, a blade polishing numerical control machining center Y-axis movable sliding table, a tailstock L-axis sliding table, a blade polishing numerical controlmachining center Z-axis movable sliding table, a rotary shaft pedestal and a numerical control system. Any two of the blade polishing numerical control machining center X-axis movable sliding table,the blade polishing numerical control machining center Y-axis movable sliding table and the blade polishing numerical control machining center Y-axis movable sliding table are perpendicular. Accordingto the ten-shaft polishing numerical control machining center, horizontal polishing of medium and large blades and vertical polishing of small blades both can be achieved, or flexible arrangement isachieved according to the requirements of the polishing process, operation is simple, and the application range is wide.

Description

technical field [0001] The present application relates to the technical field of polishing numerical control, in particular to a blade polishing numerical control machining center with ten motion axes. Background technique [0002] Blades are a very important type of aero-engine parts, which play a key role in the performance of the engine. The performance of an aeroengine depends largely on the quality of the blades, and the quality of the blades also has a direct impact on the safety and reliability of the engine. Manufacturing blades with high geometric precision and good surface quality is of great significance for improving the performance and quality of aero-engines. [0003] Aeroengine blades are typical thin-walled complex free-form parts, and the materials used are all difficult-to-machine materials. Take titanium alloy, which has the largest utilization rate in blade manufacturing, as an example. Titanium alloy has light weight, high strength, good high and low te...

Problems solved by technology

In 2013, the company developed the TX6-1000HV six-axis linkage CNC abrasive belt grinder for the grinding of the air intake and exhaust edges of aero-engine blades, which can be used for polishing the air intake and exhaust edges of aero-engine titanium alloy precision forging blades and the airfoil profile. But it is only used for horizontal processing of large and medium blades

[0009] With the in-depth development of my country's aviation industry, the blade profile is becoming more and more complex, and new structures such as wide-chord blades, sweep-shaped blades, and bow-shaped blades have appeared. The current polishing method in a single form can no longer solve the high-precision polishing of all parts of the blade.

For blades of different structures and materials, different polishing methods need to be adopted. Considering the feeding method, process mode, and special requirements of abrasive tools, the processing technology is becoming more and more complicated.

At the same time, polishing of each part requires a large difference in the movement form and specification parameters of the machine tool, and it is difficult to complete the polishing of different parts of the blade on the same machine tool
