Large direct-drive numerical control rotary table

Abstract

The invention discloses a large direct-drive numerical control rotary table. The large direct-drive numerical control rotary table comprises a workbench and a rotary table body, wherein a torque motoris arranged in the rotary table body, the torque motor comprises a torque motor stator and a torque motor rotor, the torque motor stator is fixedly connected with the rotary table body, the torque motor rotor is fixedly connected with the workbench, and the direct drive workbench rotates relative to the rotary table body when the torque motor is powered on. The large direct-drive numerical control rotary table adopts the direct drive type torque motor to directly drive the workbench, and has the characteristics of large bearing, large torsion and high precision, and meanwhile, the mechanicalstructure is simplified; the torque motor has an ultra-long service life and is extremely low in abrasion, energy and materials are greatly saved, and the large direct-drive numerical control rotary table has high energy-saving and environment-friendly performance.

Description

technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a large direct-drive numerical control turntable. Background technique [0002] The working turntable is an important functional part of the machining center. Its rotary motion is linked with other linear axes and can process various complex curved surfaces or special-shaped parts. [0003] The CNC direct-drive turning-milling compound rotary table is the most ideal and most important functional part of the compound processing machine tool. The CNC direct-drive turning-milling compound rotary table in the prior art is controlled by a servo control system, and single and double servo motors are used to pass through a set of Or multiple sets of reducers with multi-stage gears, ring gears or other methods to drive the workbench have the disadvantages of complex mechanical transmission mechanism, small load, low efficiency and high noise. The process requires high e...
