Torque motor drive electric spark total immersion liquid rotary table

Abstract

The invention relates to the technical field of non-traditional machining, in particular to a torque motor drive electric spark total immersion liquid rotary table. The torque motor drive electric spark total immersion liquid rotary table comprises a supporting shell, a workbench, an output rotation shaft and a torque motor. The torque motor is arranged in an inner cavity of the supporting shell.A stator of the torque motor fixes the supporting shell, and a rotor of the torque motor fixes the output rotation shaft. The output rotation shaft is connected with the supporting shell through a bearing. The front end of the output rotation shaft stretches out of the supporting shell and is connected with the workbench. A high-resolution encoder is arranged at the rear end of the output rotationshaft, a rear cover plate is arranged at the rear end of the supporting shell, the total immersion liquid rotary table is sealed, and the workbench is connected with a power feeding mechanism. The torque motor drive electric spark total immersion liquid rotary table is suitable for vertical and horizontal dual purposes, vibration and noise caused by a mechanical structure are reduced, and the requirements for sealing performance, precision and reliability in the electric spark total immersion liquid machining process are well met.

Description

technical field [0001] The invention relates to the technical field of special processing, in particular to a full immersion turntable for electric spark driven by a torque motor. Background technique [0002] The CNC rotary table for EDM is an important accessory of modern high-end EDM machine tools. It can perform continuous indexing and high rotation precision. As an important accessory of multi-axis CNC EDM machine tools, it directly affects the overall processing performance of the machine tool. In recent years, although domestic multi-axis large-scale CNC EDM machines have developed rapidly, most of the large-scale EDM CNC turntables that match them are imported equipment, and large closed impellers and crowned turbine disks in aviation, aerospace, energy and other fields are difficult Adding materials and special-shaped parts requires large-scale multi-axis EDM equipment, and a large-scale fully-immersed CNC turntable independently developed by itself is required. ...
