Fastener Insertion Force Correlation Between Rivet Gun and Press
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The forces exerted by a rivet gun during fastener insertion can degrade components, while hydraulic presses used for testing do not accurately replicate these forces, leading to potential damage in manufacturing.
Innovation Solution
A system and method using force sensors to correlate the forces exerted by a rivet gun with those of a hydraulic press, employing a control unit to analyze and predict the impact of rivet gun forces based on data from both tools, ensuring safe and effective fastener installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic press is used to test fasteners, then testing can be performed, but the forces exerted by the press do not accurately replicate rivet gun forces, leading to potential component damage
Solution Approach 1:
The system uses force sensors to measure actual forces during both press testing and rivet gun operations, feeding this data back to a control unit that correlates the two different force profiles. This feedback loop enables accurate translation of press test results to predict rivet gun forces, preventing component damage while maintaining testing reliability
Solution Approach 2:
Force sensors act as intermediaries between the mechanical tools (press and rivet gun) and the control system. These sensors capture force data from both tools, enabling the control unit to correlate and translate forces between the two different insertion methods without direct mechanical connection
2Measurement precision
If force sensors and control systems are added to correlate rivet gun and press forces, then accurate force prediction is achieved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical force replication mechanisms with electronic sensing and computational correlation. Instead of mechanically adjusting the press to replicate rivet gun forces, force sensors and a control unit electronically correlate the force profiles, simplifying the overall system while improving measurement precision
