Abstract

The invention discloses a numerical control direct drive rotating platform which comprises a working table, a seat body, a locking sleeve and a motor, wherein the locking sleeve is mounted on the seat body; a medium channel is arranged on the seat body; the outlet of the medium channel leads to the inner wall of the locking sleeve; the motor is provided with a motor rotor and a motor stator; the motor stator is fixedly arranged; the motor rotor is fixedly connected with the working table through a connecting mechanism; the locking sleeve is arranged on the inner side of the motor rotor; when no medium is left in the medium channel, the motor operates, the motor rotor can rotate relative to the locking sleeve; when a medium is conveyed to the inner wall of the locking sleeve through the medium channel, the medium exerts a radial force, facing the motor rotor direction, on the locking sleeve, so that the outer wall of the locking sleeve tightly clings to the motor rotor under the action of the radial force, a braking force on the motor rotor is generated. The numerical control direct drive rotating platform makes braking easier, safer and more reliable.

Description

technical field [0001] The invention relates to a numerically controlled direct-drive turntable, which belongs to the technical field of machine tool turntables. Background technique [0002] At present, the direct-drive turntable is mainly used in the rotation coordinates of CNC machine tools, and is also widely used in the automatic control of the corners of radars, turrets, gyroscopes, etc. The direct-drive turntable is characterized by zero transmission, no transmission error, no wear of transmission parts, and high precision. Its remarkable features have been highly valued by related industries in recent years, and it has been continuously listed as a major national project. [0003] Among the technologies related to the direct drive turntable, an important technology is the braking technology of the turntable. At present, the main braking method is the end face braking using butterfly spring or hydraulic power. This braking method has insufficient braking force. Not v...
