Abstract

The invention provides a torque motor direct-driven full immersion rotary table comprising a supporting shell, the torque motor, an output rotary shaft and a worktable. The torque motor is fixed on the supporting shell and further sealed by a front hood and a rear hood. The output rotary shaft is directly fixed on the torque motor and penetrates the front hood in a sealed manner. The worktable is mounted on the output rotary shaft in an insulation manner. A powering structure is arranged between the worktable and a frame. By adopting the torque motor direct drive manner, the full immersion rotary table is simple in structure, small in size and high in indexing accuracy; a combined sealing manner includes pneumatic sealing, dynamic sealing, a drain-back passage and static sealing, allowing effective sealing performance; with the axial powering manner adopted, the powering system is convenient to mount to lead to good powering effect; with the two-point supporting manner adopted, the rotary table is good in bearing effect and stable in dynamic performance.

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 working fluid as the discharge medium. The commonly used working fluid is a medium with low viscosity, high flash point and stable performance, such as kerosene, deionized water and emulsion. Therefore, the key components immersed in the working fluid should have good sealing performance. If the protection is not in place, key components will be damaged. [0003] In the processing...
