Description

Technical Field

[0001] This utility model relates to the field of riveting equipment technology, and in particular to an adaptive positioning mechanism for a self-piercing riveting device. Background Technology

[0002] Self-piercing riveting is essentially a mechanical cold forming technology that can effectively connect two or more layers of sheet metal. Its connection principle involves a punch pressing down to force a rivet into the sheet metal. As the rivet penetrates the sheet, it opens outwards to form a rivet buckle, creating a permanent fastening structure within the substrate, thus tightly connecting the substrates together.

[0003] However, existing technologies still have shortcomings. They require manual positioning of materials, which is inefficient and makes it difficult to position materials of different shapes.

[0004] Therefore, we propose an adaptive positioning mechanism for a self-piercing riveting device to solve this problem. Utility Model Content
