Five-axis high-precision machining system with split transmission

Abstract

The invention discloses a five-axis high-precision machining system with split transmission. The driving motor is set independently of the machine tool foundation, so that the power source and the machine tool body are separately set. Moreover, the driving mode of a single direction adopts the driving mode of double motors and gears. It can eliminate the hysteresis during the driving process, ensure the driving accuracy, and at the same time prevent the vibration generated by the operation of the power source (motor) from being transmitted to the machine tool itself. After a long period of use, the driving accuracy of the motor is reduced, and it can still maintain linear operation and Rotation accuracy, so as to ensure the advantages of the five-axis machining system such as machining accuracy, can obtain higher dynamic characteristics, feed speed and cutting speed, and can obtain better machining surface quality and improve machining efficiency; it can automatically, high-speed, High-precision and high-efficiency continuous processing of multiple planes and complex curved surfaces of parts, suitable for aerospace, military, automobile, ship, medical, mold and other fields.

Description

technical field [0001] The invention relates to a machine tool, in particular to a five-axis linkage system. Background technique [0002] Five-axis linkage equipment belongs to the more common equipment in CNC machine tools, and is used for processing parts with complex structures; in order to ensure the final machining accuracy, it is generally equipped with high-speed direct-connected spindles and servo systems, and ball screws are equipped in X, Y, and Z directions. And linear guide rails are directly driven by servo motors with continuously variable speed, and the B and C rotation axes use servo motors to form direct-drive turntables, which can basically guarantee stable precision and high dynamic and static characteristics; Due to the long-term relatively large torsional moment, the drive shaft of the motor, the internal rotor, and the rotating pair will be slightly deformed, causing corresponding vibrations, which will be transmitted to the linear motion of X, Y, and ...
