Abstract
A rigid-flexible coupling motion platform driven by a ball screw includes a base, a linear guide rail fixed to the base, a rigid-flexible coupling platform, a servo motor, a ball screw, a guide rail sliding block, a displacement sensor and a driving controller. The rigid-flexible coupling platform includes a frame and a workbench. The frame and the workbench are connected through a flexible hinge; the servo motor is configured to drive the ball screw; the workbench is connected with the ball screw; the frame is connected with the linear guide rail by the guide rail sliding block; the displacement sensor is configured to feed back the position of the workbench; and the driving controller controls the ball screw to drive the workbench to move according to different control modes. The advantages of the ball screw drive and the rigid-flexible coupling motion platform are fully combined, and the positioning precision of the platform is greatly improved.
