Problems solved by technology

However, the use of these measurement methods is mostly aimed at a certain production link, using a single digital measurement method for measurement, less involving the process of secondary positioning of tooling and parts, and the use of measurement methods has not yet been based on various methods. The scope of application of the advantages of the measurement method, the positioning of the assembly process is realized by the method of hybrid positioning

Embodiment Construction

[0011] 1. The overall strategy and implementation process of the hybrid positioning method

[0012] The laser measuring instrument has the advantages of high precision and fast measurement speed, and has a strong advantage in measuring large-scale products. Therefore, the laser tracker is used as the measurement method for the tooling and automatic hole-making equipment in the mixed measurement and positioning. Photogrammetry equipment is small in size, easy to operate, easy to process data, and has a strong advantage in measuring a single part. Therefore, photogrammetry equipment is used as a measurement method for the position of the parts to be assembled in the hybrid measurement positioning.

[0013] The mixed measurement and positioning process of parts to be assembled in the flexible assembly of aircraft components is divided into two steps. First of all, the relative positional relationship between the automatic hole-making equipment and the tooling is established thr...

Abstract

The invention discloses a hybrid measurement method for positioning a part to be assembled in the flexible assembly process of airplane components, belonging to the research contents of modern manufacturing technology in the field of advanced manufacturing technology. The method is a measurement positioning method for establishing a relative positional relationship between automatic hole making equipment and the part to be assembled in the flexible assembly process of the airplane components. The method adopts a laser measurement apparatus as a rough positioning means of the hole making equipment and adopts photographing measurement equipment as a means of accurately positioning the part to be assembled, and realizes accurate positioning of the part to be assembled by two steps. Through the method, the problem of incoordination between the automatic hole making equipment and a workpiece to be assembled resulting from excessive error accumulation of the assembly process in the flexible assembly process of the airplane components is solved to a certain degree, and an effective means of using automatic equipment in the flexible assembly of the airplane components is provided.
