Machine tool rotating unit and casing part high-precision rotary printing electrolytic machining machine tool

Abstract

The invention discloses a machine tool rotating unit and a casing part high-precision rotary printing electrolytic machining machine tool. The machine tool rotating unit comprises a rotating conductive ring, a core shaft, a hollow main shaft, a torque motor and a main shaft seat; a rotating conductive ring stator is connected with the main shaft seat, a conductive ring rotor is connected with thecore shaft, the core shaft is fixedly connected with the hollow main shaft through an insulation supporting sleeve in an insulation mode, the hollow main shaft is responsible for clamping of a workpiece, and the core shaft is responsible for electrode electricity leading; a torque motor stator is connected with the main shaft seat through a shaft sleeve, a motor rotor is directly connected with the hollow main shaft, a cooling channel is designed in the rotating unit, and the cooling channel can also be used as a liquid supply channel for electrolytic machining so as to realize the internal liquid supply of a tool cathode. Compared with the design of an existing electrolytic machining machine tool that the transmission mode of connecting the servo motor and a speed reducer with the main shaft is adopted and the main shaft is responsible for force bearing and electricity leading, the machine tool has the characteristics that the transmission precision is high, allowable machining current is large, the advantages of high-efficiency machining of electrolytic machining are brought into full play, and the application range of rotary printing electrolytic machining is expanded.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a high-precision spin-printing electrolytic machining machine tool for a machine tool rotary unit and casing parts. Background technique [0002] The casing is a key component of an aero-engine, which is responsible for protecting the core internal structure of the engine, providing a place for fuel combustion and providing support for peripheral components and pipelines. There are many casing parts on the engine, including intake casing, fan casing, combustion chamber casing, intermediate casing, turbine casing, external casing, etc. The casing is large in size, mostly thin-walled rotary parts, and has a boss structure with complex contours on the surface. In order to meet the requirements of high temperature and high pressure work, most of the materials used are difficult-to-machine materials such as titanium alloys and high-temperature alloys.
