Description

Technical Field

[0001] This utility model relates to the technical field of rivet stamping devices, specifically a rivet stamping device for new energy vehicle battery packs. Background Technology

[0002] New energy vehicles, broadly defined as alternative fuel vehicles, include pure electric vehicles and fuel cell electric vehicles that use only non-petroleum fuels, as well as hybrid electric vehicles and ethanol gasoline vehicles that partially use non-petroleum fuels. In the production process of pure electric vehicles, the battery pack requires rivets to securely connect the battery pack casing, which involves the use of rivet stamping equipment.

[0003] A Chinese utility model patent (publication number: CN202322785849.1) discloses a rivet stamping fixture for new energy vehicle battery packs. The fixture includes a base, a rotating table rotatably mounted on the base, and a vertical support column on one side of the base. A top plate is horizontally fixed to the top of the support column. A cylinder is mounted on the top plate, with its telescopic end penetrating the top plate. A first pressure plate is rotatably mounted at the bottom of the telescopic end of the cylinder. A horizontal plate is mounted on the telescopic end of the cylinder, with one end rotatably connected to the telescopic end of the cylinder and the other end having an extension plate inserted into it. The extension plate slides with the horizontal plate, and a screw is vertically threaded through the outer end of the extension plate, connected to the extension plate by a thread. A second pressure plate is rotatably mounted at the bottom of the screw. This device facilitates rivet stamping by placing the battery pack on the rotating table and pressing it with the first pressure plate.

[0004] The aforementioned patent describes a rotating table that can rotate, but the pressure plate cannot rotate synchronously with the rotating table. During rotation, the battery pack may be displaced or vibrate, increasing the risk of stamping errors. Therefore, a rivet stamping device for new energy vehicle battery packs is proposed to overcome the above problems. Utility Model Content
