Description
Technical field
The present invention relates to numerically controlled lathe drive technology field, be specifically related to a kind of numerically controlled lathe traverse feed drive mechanism.
Background technology
Along with the maturation of China's lathe-techniques, numerically controlled lathe also develops the rapidest.Lead screw transmission mechanism is widely used in
The fields such as Digit Control Machine Tool.In existing lead screw transmission mechanism, motor and the usual axle center of drive lead screw are positioned at the installation of same straight line, motor
Electric axis directly drives drive lead screw to rotate.During drive lead screw positive and negative rotation, stress is at an axis direction, by installing accumulated error
Affecting and motor-driven vibration influence, the absolute precision required for drive lead screw is higher.
In large-size numerical control machine feed system, feeding driving mechanism is non-on the impact of whole feed system precision, rigidity
Chang great.Current lathe transverse feed mechanism just cannot ensure rigidity while ensureing big stroke, and volume is big, and transmission is imitated
Rate is low.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
