Abstract

The invention provides a total immersion liquid numerical control turntable for an electric spark machine tool. The numerical control turntable comprises a sealed turntable box; an alternating current servo motor, a harmonic transmission speed reducer, a transmission mechanism and a rotating main shaft are arranged in the turntable box; the output shaft of the alternating current servo motor is directly connected with the input shaft of the harmonic transmission speed reducer; the harmonic transmission speed reducer and the rotating main shaft are arranged in the turntable box; the output shaft of the harmonic transmission speed reducer is arranged in parallel to the rotating main shaft connected with the numerical control turntable; the transmission mechanism is arranged between the output shaft of the harmonic transmission speed reducer and one end of the rotating main shaft; and the other end of the rotating main shaft extends out of the turntable box in a sealing manner, an electric brush is connected to the rotating main shaft, and a pneumatic chuck capable of supporting a quick change system is assembled on the extending end. The rotating component of the numerical control turntable is high in sealing property, precision guarantee technology and reliability; and the numerical control turntable is simple in manufacturing process and good in protective property.

Description

technical field [0001] The invention belongs to the technical field of special processing, and in particular relates to a full-immersion numerical control turntable for an electric discharge machine tool. Background technique [0002] EDM technology uses the heat energy generated by pulse discharge to etch away the material of the workpiece. It is mainly used for the processing of materials with high hardness, high strength, high melting point, high toughness and high brittleness that are difficult for mechanical processing, and can complete precise and complex Machining of shape parts. EDM uses the working fluid as the discharge medium, the working fluid forms a spark to penetrate the discharge channel, and quickly restores the insulation state of the gap after the discharge; it compresses the discharge channel; it helps the electro-erosion products to be thrown out and removed; The workpiece plays a cooling role. The transmission parts immersed in the working fluid shoul...
