Sliding Part Coupling for Driveshaft Tube Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for simultaneously attaching end fittings to driveshaft tubes of varying lengths are inefficient due to length discrepancies, which prevent proper positioning and successful welding.
Innovation Solution
A welding apparatus with selective axial movement capabilities, including position sensors and hydraulic devices, adjusts the axial location of workpieces to account for length differences, allowing simultaneous welding of workpieces with varying lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tubes of varying lengths are inserted into the welding machine, then productivity is improved by simultaneous welding capability, but manufacturing precision deteriorates due to inability to properly position welding apparatus
Solution Approach 1:
The welding machine incorporates adjustable positioning mechanisms that can dynamically adapt to different tube lengths. The welding apparatus includes movable clamps and positioning devices that can be adjusted along the tube axis to accommodate length variations while maintaining precise welding position alignment.
Solution Approach 2:
The system changes positioning parameters based on detected tube length variations. Sensors measure the actual tube length and the control system adjusts the welding apparatus positioning parameters accordingly, allowing simultaneous welding of tubes with different lengths while maintaining manufacturing precision.
2Adaptability or versatility
If tubes with slight length variations are processed, then adaptability is improved to handle real-world manufacturing tolerances, but device complexity increases to accommodate positioning adjustments
Solution Approach 1:
The welding machine incorporates sensors that automatically detect tube length variations and trigger appropriate positioning adjustments. The system self-regulates by measuring the actual tube dimensions and automatically compensating through controlled movement of welding apparatus components, reducing the need for complex manual adjustment mechanisms.
Solution Approach 2:
The system uses feedback from length measurement sensors to continuously monitor tube dimensions and adjust positioning in real-time. The control system receives feedback about tube length variations and automatically modifies the positioning of welding apparatus to maintain accurate welding positions despite length variations.

AI summary
A method of joining workpieces includes locating first ends of two first workpieces in a moveable part coupling portion. The lengths of the first workpieces are measured. Any difference in length between the first workpieces is determined. Two additional workpieces are located adjacent the first ends of the first workpieces based on the determined difference in length. The first workpieces are connected to the second workpieces.
