Description

technical field [0001] The invention is a mechanical device for improving the resolution and measurement accuracy of an angle encoder, especially a mechanical device for increasing the number of gratings of an angle encoder and improving its measurement accuracy by using the macro-micro composite idea, which belongs to high redundancy Innovative technology for angle encoders. Background technique [0002] In the modern machining industry, grating sensors are mostly used as position feedback devices. Because the grating scale can implement full closed-loop control of the system, reduce the error caused by the thermal deformation of the ball screw and improve the machining accuracy, the angle encoder is one of the grating scales, so the current medium and high-end CNC systems are increasingly used Angle encoder as angle feedback element [1] . Its high precision and high resolution combined with a relatively low price make it widely used not only in the field of machine tool...
