Description

technical field [0001] The invention relates to a high-precision rotary worktable, in particular to a high-precision and high-speed rotary worktable directly driven by a built-in torque motor, belonging to the technical field of machining. Background technique [0002] The existing rotary table in our country generally adopts traditional transmission mechanisms such as gears, worm gears, or end sprockets. High energy consumption cannot meet the needs of high-speed and high-precision machine tools. [0003] The rotary table directly driven by the torque motor has a simple, stable transmission structure, high precision, and fast response, but its rotation speed is low, the braking effect is not obvious, and the rotary table will also vibrate during cutting. Contents of the invention [0004] The technical problem to be solved by the present invention is that the rotary table driven by the transmission mechanism has complex structure and low precision, while the rotary table...
