Abstract

The invention discloses a measurement data processing method for pose measurement and adjustment in digital assembly of large-sized parts, comprising the following steps: comparing the current pose of a digital theory model matching assembly part according to actually measured data; and calculating actual optimal target assembly poses according to the current pose. The position of each critical characteristic on the part and corresponding detection points of each assembly detection item are measured by using a laser tracking instrument. Measurement data after processed by the method can provide accurate assembly position and pose data and positioning adjustment parameters for a large-sized part digital flexible assemble system, and the optimal assembly effect of parts is achieved by matching real-time measurement.

Description

Technical field:

[0001] The invention relates to a method for matching the best assembly posture in the digital assembly measurement process of large parts. Background technique:

[0002] Measurement-assisted assembly technology is one of the effective ways to realize the digital assembly of large-scale products and control the assembly quality and key characteristics. Portable large-scale measuring equipment is used to track and measure the pose of each component in real-time during product assembly, and check the position of key features. Meet the technical requirements of product assembly quality. The precise adjustment and control of the pose in the assembly of large parts is one of the key points to ensure the accuracy of product assembly, especially when the parts are docked and the final assembly of the product is more prominent.

[0003] Assembly pose matching is a key part of measurement data processing in the digital assembly of large parts. Assembly accuracy to ...
