Abstract

The invention provides a blade air inlet and outlet edge six-axis electric spark machining machine tool. According to the blade air inlet and outlet edge six-axis electric spark machining machine tool, a Y-direction linear moving shaft is fixed on the horizontal plane of a special machine tool body through two positioning grooves and is connected with an X-direction linear moving shaft through a Y-axis sliding rail, two cradle mechanisms are connected to the X-direction linear moving shaft, one side of a first cradle is connected with a B-rotation-direction rotating shaft, one side of a second cradle is connected with an A-rotation-direction rotating shaft, the second cradle is connected with a blade clamp, a Z-axis supporting plate is arranged on the left end face of the machine tool body to fix a Z-direction linear moving shaft, the Z-direction linear moving shaft fixes a C-rotation-direction rotating shaft through a sliding block, a transverse plate, a bearing box and other accessories, the C-rotation-direction rotating shaft is connected with an electrode clamp through a shaft, and a hole site is formed in the inner side of the electrode clamp to be used for being connected with an actuator so as to provide vibration during machining. The blade air inlet and outlet edge six-axis electric spark machining machine tool is compact in structure and easy to assemble, six-degree-of-freedom space complex movement can be achieved, the blade edge arc machining efficiency is improved, and multi-degree-of-freedom electric spark machining can be stably and reliably conducted on blade air inlet and outlet edges.

Description

technical field [0001] The invention relates to a six-axis electric spark machining machine tool for blade inlet and exhaust sides, and belongs to the technical field of precision machining of machine tools. 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 aero-engines and are known as the "heart" of aero-engines. In the world, the comprehensive industrial strength of a country is often reflected by the research and development and processing technology level of aero-engines. In the entire process of aero-engine processing, the processing volume of blades accounts for one-third of the total processing volume, so the processing quality of blades determines the processing quality of the engine to a large extent. The blade is the main part of the aero-engine, and the inlet and exhaust edges...
