Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] The invention relates to a high-speed dynamic measurement method for digital flexible assembly of components, which specifically includes the following steps:
[0022] Step 1. Install more than four laser trackers, use each laser tracker to measure the common control points, establish the spatial relationship of the coordinate system of all laser trackers, and form a measurement system;
[0023] Step 2, using the reference ruler standard device to carry out on-site calibration of the comprehensive measurement accuracy of the measurement system;
[0024] Step 3. Use any laser tracker to measure the pre-calibrated global control points, and establish the conversion relationship between the measurement coordinate system and the global coordinate system;
[0025] Step 4, using any laser tracker to measure the product reference of the passi...

The invention belongs to the technical field of geometric precision measurement, and specifically relates to a high-speed dynamic measurement method of part digitalization flexible assembling. The method specifically includes following steps: step 1, establishing a measuring system; step 2, performing field calibration; step 3, establishing a conversion relation between a measurement coordinate system and a global coordinate system; step 4, establishing a conversion relation between a passive butt joint portion product coordinate system and the measurement coordinate system; step 5, reaching a designated position by the passive butt joint portion; step 6, establishing a conversion relation between an active butt joint portion product coordinate system and the measurement coordinate system; step 7, installing monitoring points at an active butt joint portion; step 8, performing real-time dynamic measurement on three-dimensional position attitude of the active butt joint portion; step 9, obtaining a position attitude deviation of two portions; and step 10, determining whether the designated position is reached. According to the method, dynamic measurement is realized in the real sense, and the speed and the dynamic performance of a measuring system in ultra-large part digitalization flexible assembling are effectively increased.
Description
technical field [0001] The invention belongs to the technical field of precision measurement of geometric quantities, and in particular relates to a high-speed dynamic measurement method for digital flexible assembly of components. Background technique [0002] With the development of large-scale advanced equipment manufacturing in the direction of digitalization, automation, and flexibility, digital flexible assembly of super-sized components is an indispensable and important part, which is equally important with digital automated processing. The digital flexible assembly system for super-sized parts is a closed-loop control system integrating digital measurement, flexible motion and automatic control. The measurement unit is the eye of the entire assembly system and is an essential and important part. [0003] At present, the development and application of digital flexible assembly systems for super-large components are still in their infancy in China. Most of the large-sc...
