Abstract

The invention discloses a double-drive speed regulation rotary table of a numerical control machine tool, and belongs to the technical field of numerical control machine tools. The rotary table comprises a rotary table seat and a rotary table frame rotationally connected to the inner side of the rotary table seat, a table body is mounted in the rotary table frame, and the table body is rotationally connected with a workbench; the rotary table also comprises a planet wheel mechanism, anda workbench is connected with a wheel carrier of the planet wheel mechanism; and a center wheel of the planet wheel mechanism is connected with a first power source, a gear sleeve of the planet wheel mechanism is connected with a second power source, and the workbench is driven to rotate through the first power source and/or the second power source. The two power sources and the planet wheel mechanism are coordinated to synthesize power to be input to the workbench, and control over the speed, torque and position of the rotary table workbench is achieved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a double-drive speed-regulating turntable of a numerical control machine tool. Background technique [0002] As a carrier for controlling workpiece rotation in CNC machine tools, the turntable plays a very important role. At present, the known turntables used on high-end CNC machine tools can only realize the functions of milling, drilling and boring of the machine tool, and the turning function cannot be realized. The reason why the turning function cannot be realized is mainly the milling, drilling and boring of the machine tool. Boring and other processes require low speed and high torque, while turning processes require high linear speed. Therefore, this is undoubtedly a fatal flaw for high-end CNC machine tools, which limits the application range of CNC machine tools. [0003] The prior art also discloses a two-axis numerical control turntable, which...
