Vertex coordinate correction device and method for quick-wear parts

The invention relates to a vertex coordinate correction device and method for quick-wear parts. The vertex coordinate correction device for the quick-wear parts comprises two visual identity systems, wherein the two visual identity systems correspond to an uptake plane A and an uptake plane B; the uptake plane A and the uptake plane B are perpendicular to each other; a calibration point a and a calibration point b are correspondingly formed in the uptake plane A and the uptake plane B; perpendicular lines l1 and l2 are constructed on the intersecting line L of the uptake plane A and the uptake plane B by virtue of the calibration point a and the calibration point b; and the perpendicular lines l1 and l2 are intersected on a point c on the intersecting line L of the uptake plane A and the uptake plane B. The correction device disclosed by the invention is simple in structure and small in size and can be assembled on automatic equipment, and the correction can be directly performed after the quick-wear parts are replaced; the correction time is short, and the correction accuracy is high; and moreover, the quick-wear parts can be needle heads of dispensers, spot welding heads of spot welders and other parts.
