Abstract
The application discloses a kind of tool butt joint method and system, including end setting with laser range finder, positioning tool interface is provided with measured piece;When reaching the position to be corrected, the laser measurement height value is read by laser range finder;The correlation analysis of the installation offset of laser range finder and the projection point on measured piece is carried out, and the coordinate relationship equation is established;Offset is calculated according to coordinate relationship equation, whether offset meets the requirement is judged, if it meets the requirement, then butt joint is completed, if it does not meet the requirement, then translation adjustment is carried out.The application is tested in laboratory, can control robot end absolute positioning accuracy to be below Β±0.25mm, satisfies the requirement that robot completes butt joint operation;Uniform processing standard and gauge standard batch processing measured target are used, and quick replacement can be realized;3-point correction algorithm is used, installation error is weakened, and calculation error caused by installation error is further reduced.
