Self-Piercing Rivet Apparatus with Separable Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-piercing rivet installation systems lack flexibility and accessibility, as the installation head is often inseparable from the drive spindle, limiting their ability to install rivets in various orientations and locations, and requiring complex tooling and increased installation time.
Innovation Solution
A self-piercing rivet installation apparatus with a separable installation head and reversible anvil mounting assembly, allowing for interchangeable mounting structures and operation in two opposite directions relative to the rigid C-frame, enabling riveting in a variety of orientations and locations without the need for extensive tooling adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the installation head is inseparable from the drive spindle, then the system structure is simpler, but the flexibility and accessibility for installing rivets in various orientations and locations is reduced
Solution Approach 1:
The installation head is separated from the drive spindle, allowing them to be independent components. The drive spindle remains attached to the C-frame while the installation head can be mounted on either the drive spindle or the mounting post, enabling flexible configuration without requiring a completely integrated design.
Solution Approach 2:
The anvil mounting assembly is designed to be alternatively mountable on both the drive spindle and the mounting post. This universal mounting capability allows the same assembly to serve multiple positions and orientations, increasing the system's adaptability for different riveting applications.
2Ease of repair
If the installation head is inseparable from the drive spindle, then fewer components are needed, but service and adjustment of the installation head becomes more difficult
Solution Approach 1:
By separating the installation head from the drive spindle as distinct components, the system allows the installation head to be easily removed, serviced, or adjusted without affecting the drive spindle or requiring disassembly of the entire C-frame structure.
3Adaptability or versatility
If complex tooling is used to achieve rivet installation in various orientations, then accessibility is improved, but installation time and tooling costs increase
Solution Approach 1:
The system allows dynamic reconfiguration by enabling the anvil mounting assembly to be moved between the drive spindle and the mounting post. This dynamic adaptability provides accessibility to various orientations without requiring multiple fixed tooling configurations, reducing setup time and tooling complexity.

AI summary
A self-piercing rivet installation apparatus includes a rigid C-frame and a drive spindle translatable along a rivet installation axis through a first jaw of the rigid C-frame. An installation head has an installation head mounting end mountable to a leading end of the drive spindle. A mounting post having a mounting post root end is matingly engaged with a jaw socket defined coaxially with the rivet installation axis in a second jaw of the rigid C-frame. A coupling tube has a coupling tube mounting end. A riveting anvil is removably mounted to the coupling tube to form an anvil mounting assembly. The anvil mounting assembly is alternatively mountable on the drive spindle and the mounting post. The installation head is alternatively mountable on the mounting post and the drive spindle opposite the anvil mounting assembly.
