Edge Distance Determination for Aeronautical Thin-Walled Structures with Automated Riveting

摘要

In the process of automated riveting,the position between the riveting head and the holes distributed on the stringer and wing skin to be riveted will go beyond the design requirements currently.Using the edge distance determination technology to measure and compensate the deviation in time is one effective method to solve this problem.In the dissertation,after the characteristic of the edge distance determination technology is introduced,the working principle of the edge distance tracer apparatus is developed.Based on the mechanical design solution,a pressure sensor is selected to measure the position relationship between the riveting head and the stringer.Then an edge distance tracer apparatus is struck out to detect the deviation,which is an automatic positioning feedback device that can be fit for many kinds of stringers.And the riveting head is operated to meet the design deviation requirements.By using this technology,the drilling precision of the automated riveting system can be effectively improved.
