Abstract

The invention provides a six-axis EDM machine tool for blade inlet and exhaust sides. The special machine tool bed is fixed with two positioning grooves on the horizontal plane of the Y-direction linear moving axis; Linear movement axis; two cradle mechanisms are connected to the X-direction linear movement axis, the first cradle is connected to the B rotation axis, the second cradle is connected to the A rotation axis, the second cradle is connected to the blade clamp, the left end of the bed There is a Z-axis support plate on the surface to fix the Z-direction linear moving axis. The Z-direction linear moving axis fixes the C-rotation rotation axis through the slider, horizontal plate, bearing box and other accessories; the C-rotation rotation axis is connected to the electrode fixture through the shaft. There are holes on the inside of the fixture to connect the actuator to provide vibration during machining. The invention has compact structure and simple assembly, can realize complex movement in space with six degrees of freedom, improve the machining efficiency of the blade edge circular arc, and can stably and reliably perform multi-degree-of-freedom EDM machining on the edges of the intake and exhaust of the blade.

Description

technical field [0001] The invention relates to a six-axis electric spark machining machine tool for the inlet and exhaust sides of blades, and belongs to the technical field of machine tool precision machining. Background technique [0002] Aviation manufacturing technology has always been a cutting-edge technology. Aircraft engine technology is the crown of aviation manufacturing technology. Blades play an important role in energy conversion in aeroengines and are known as the "heart" of aeroengines. In the world, the comprehensive industrial strength of a country is often reflected by the level of research and development and processing technology of aero-engines. In the whole process of aero-engine processing, the processing volume of the blade accounts for one-third of the total processing volume, so the processing quality of the blade determines the processing quality of the engine to a large extent. The blade is the main part of the aero-engine, and the intake and ex...
