Numerical control machine tool workpiece positioning system based on picture recognition

Abstract

The invention discloses a numerical control machine tool workpiece positioning system based on picture recognition, which comprises a machine tool main body, a camera, a light source, a numerical control system and a workbench, and is characterized in that the machine tool main body comprises a machine tool metal plate and a machine tool spindle, and the machine tool spindle is perpendicular to and protrudes out of the machine tool metal plate; four positioning reference blocks and a reference size block are fixedly arranged on the working table, the numerical control system comprises a display screen, the display screen is used for man-machine interaction of the numerical control system, and according to mechanical coordinates of the positioning reference blocks, in combination with bitmaps of workpieces or cavities shot by the camera, and through calculation of a workpiece positioning program, the workpieces or the cavities can be positioned. According to the method, the center coordinates of the workpieces or the cavities are obtained, then follow-up machining is conducted, the traditional operation step that an operator manually moves electrodes or reference balls to the approximate center positions of the multiple workpieces or the cavities is not needed, a large amount of repeated operation time is saved, the technical requirement for the operator is lowered, and the production efficiency is greatly improved.
