Abstract

The invention provides a measurement and jet printing integrated device and method for a complex curved surface, and belongs to the field of advanced manufacturing, and the device comprises a motion module, a jet printing and measurement module, an integrated control module, a voltage control module and an air pressure control module. And the motion module can move independently, so that the functions of measuring and jet printing function switching and jet printing height adjustment according to the measured height are realized. The jet printing and measuring module is used for achieving the functions of pattern jet printing and jet printing height detection in the technological process. According to the method, the mode that the actual height of the jet printing needle and the surface of the workpiece is measured multiple times in the jet printing process and the height of the spray head is adjusted is adopted, the height change of the spray head in the complex curved surface jet printing process is reduced, the defects caused by inaccurate digital analog in the complex curved surface jet printing machining process are reduced, and the production efficiency is improved. The problems that in a complex curved surface application scene, the jet printing height of an existing jet printing method cannot be changed according to the curved surface height, so that the jet printing quality is low, and defects are serious are solved, and the jet printing quality is improved.
