Abstract

The utility model provides an accurate positioning device for a high-precision numerically controlled lathe, which relates to the field of numerically controlled lathe positioning devices and comprises a lathe body, an adjusting component is arranged at the bottom of an inner cavity of the lathe body, and a positioning component is arranged at the top of the adjusting component. The output end of the electric push rod drives the movable plate and the clamping plate to move towards one side of the workpiece, the clamping plate drives the rubber pad to make contact with the workpiece, positioning of the workpiece is achieved, the rubber pad can adapt to the surface of the irregular workpiece through the deformability of the rubber pad, the workpiece positioning range can be enlarged, and the workpiece positioning precision is improved. The output end of an electric push rod drives a movable plate, a clamping plate, a rubber pad and a workpiece to move, left-right position adjustment of the workpiece can be achieved, an output shaft of a servo motor drives a transmission rod and a gear to rotate, and due to the fact that the gear is meshed with a toothed plate, the gear can drive the transmission rod and the servo motor to move towards one side while rotating; the transmission rod drives the connecting rod, the positioning assembly and the workpiece to move, and therefore the front-back position of the workpiece is adjusted.
