The invention provides a double-way lifting driving mechanism for a twisting frame. The mechanism comprises a stand; a servo motor is connected with a first ball screw and a second ball screw through a transmission mechanism; a screw nut seat is connected with a second lifting pulling rod; a nut seat board of the first ball screw is supported on a first guide rail through a second sliding block; a third screw bearing block and a stepping motor are arranged on the nut seat board; a third screw is mounted into the third screw bearing block by a rotating manner and is connected with the stepping motor through the transmission mechanism; a third screw nut seat is arranged on the third screw and connected with the first lifting pulling rod. According to the mechanism, one more screw which is individually driven through the motor is arranged on the nut seat board of the first ball screw, and the lifting in two ways is synchronous and performed in ratio during spinning; when not spinning, the lifting in two ways can be kept in a distance, thus a relatively large space is provided, and the operation is convenient.
