Floating Element Nest Alignment for Setting Welding Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing setting welding devices have complex element supply systems that require multiple drives and sensor technologies, leading to increased construction and control efforts, and often struggle with precise alignment and tolerance compensation between the welding auxiliary joining part and the electrode punch.
Innovation Solution
A simplified element supply apparatus using a linear drive with a movable element nest that can change direction via a mechanical coupling component, allowing for efficient positioning of the welding auxiliary joining part at the joining location without additional sensor technology or drive efforts, and an element nest with floating support and springing jaws for tolerance compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple drives and sensor technologies are used to transfer the welding auxiliary joining part from a clamp arrangement to the joining location, then the positioning precision and reliability of the element supply system is improved, but the device complexity and construction effort increase significantly
Solution Approach 1:
The patent combines multiple transfer functions into a single clamp arrangement that can directly transfer the welding auxiliary joining part from the magazine to the joining location. This eliminates the need for separate transfer units and multiple drives, reducing system complexity while maintaining positioning precision through the integrated clamp design
Solution Approach 2:
The clamp arrangement is designed to automatically position and transfer the welding auxiliary joining part using its own mechanical structure, without requiring external sensor technology or complex control systems. The clamp's mechanical design inherently ensures precise positioning and reliable transfer
2Measurement precision
If a profile channel with large interfering contour is used to align the element nest to the electrode punch, then the positioning accuracy is improved, but the interfering contour and installation space requirements increase
Solution Approach 1:
The patent removes the profile channel component entirely from the system. Instead of using a large profile channel to guide alignment, the design directly positions the element nest relative to the electrode punch through simplified mechanical relationships, eliminating the interfering contour while maintaining alignment precision
Solution Approach 2:
Rather than using a large guiding structure (profile channel) to achieve alignment, the patent inverts the approach by using the electrode punch itself as the reference and positioning the element nest directly against it, thereby achieving precise alignment with minimal interfering contour
3Reliability
If complex clamp constructions with sensors and drives are used to secure the transfer of welding auxiliary joining parts, then the reliability of the transfer process is improved, but the control electronics and installation space requirements increase
Solution Approach 1:
The clamp arrangement is designed to perform the transfer function through its own mechanical design, without requiring external sensors or drives. The clamp's structure inherently ensures reliable transfer by mechanically securing the welding auxiliary joining part and releasing it at the correct position, making the system self-sufficient

AI summary
An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.
