Description

Technical Field

[0001] The utility model relates to the field of riveting, and more specifically to a riveting positioning platform for server sheet metal parts. Background Art

[0002] Pull rivets are a fastening method that uses the principle of Hooke's law. After clamping two parts with special rivet equipment, the metal of the inserted annular ring (or nut without threads) is squeezed and filled into the groove of the bolt with multiple annular grooves, so that the ring and the bolt are tightly combined.

[0003] When producing servers, the sheet metal parts of the servers often require a riveting process. Before the sheet metal parts are riveted, they need to be positioned to prevent the sheet metal parts from moving during riveting, thereby ensuring the quality of the riveting. For example, a Chinese utility model patent discloses a multi-position combined rapid riveting device (application number: CN202122850848.1), which includes a base, a fixing plate and a plurality of locating pins, and the locating pins are fixed on the base. The main parts of the product are positioned by the locating pins, but the locating pins are fixed on the base and cannot be limited and moved. When it is necessary to rivet other products with different locating hole positions, the corresponding device needs to be remade, which is not only very inconvenient, but also increases the production cost.
