Description

Technical Field

[0001] This application relates to the field of automotive large metal parts manufacturing technology, and in particular to an elastic riveting structure for automotive large metal parts. Background Technology

[0002] Large metal parts are an important component of automobiles. They typically refer to metal components used to support and fix the vehicle's body structure, such as the frame, chassis, and engine compartment. These metal parts are characterized by high strength, corrosion resistance, and long service life, providing stable and safe support and protection for the vehicle. The processing and manufacturing of these large metal parts is a crucial step in the automobile manufacturing process. To ensure the quality and safety of the vehicle, these metal parts need to undergo precision processing and manufacturing to ensure that their dimensional accuracy, surface roughness, and other indicators meet strict standards and requirements.

[0003] Many large automotive parts need to withstand high pressure for extended periods during operation, thus requiring extremely high strength and application fatigue resistance. They are typically made of high-strength alloys and machined on CNC lathes using various finishing techniques such as turning, drilling, milling, grinding, boring, and planing. However, these finishing techniques have long processing cycles, high energy consumption, and low utilization of metal raw materials, especially for larger parts, where costs are even higher.

[0004] Therefore, this application provides a flexible riveting structure for large metal parts of automobiles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an elastic riveting structure for large automotive metal parts, overcoming the deficiencies of existing technologies. It aims to solve the problem that many large automotive parts need to withstand high pressure for extended periods during operation, thus requiring very high strength and application fatigue resistance. Generally, they are made of high-strength alloy integrally on CNC lathes through various finishing processes such as turning, drilling, milling, grinding, boring, and planing. However, this finishing process has a long processing cycle, high energy consumption, and low utilization rate of metal raw materials, especially for larger parts, where the cost is even higher.

[0006] To achieve the above objectives, this application provides the following technical solution: an elastic riveting structure for large automotive metal parts, comprising a fixing block, a connecting groove inside the fixing block, a fastener at the bottom of the fixing block, an assembly at the top of the fastener, a reinforcing member fixedly connected to the top of the assembly, the assembly and the reinforcing member both matching the connecting groove, the reinforcing member being T-shaped overall, and slots on both sides of the reinforcing member, mounting grooves at positions matching the slots on both sides inside the connecting groove, and a snap-fit ​​mechanism inside each of the two sets of mounting grooves, the snap-fit ​​mechanism comprising a spring, one end of the spring being fixedly connected to the mounting groove, and a push plate fixedly mounted on the other end of the spring, with a locking block on one side of the push plate.

[0007] By adopting the above technical solution, and by setting fixed blocks and fasteners, the internal connecting grooves and assemblies are riveted together during use. This design can maximize the contact surface area between the fixed blocks and fasteners, which means that the entire joint area is large, the connection is more solid, and the overall strength of the parts is higher. This not only simplifies the processing and reduces costs, but also improves the strength and durability of the parts. It can be widely used in the production of various large metal parts for automobiles, and has high practical value and broad application prospects. It can effectively shorten the processing cycle, thereby improving production efficiency and reducing production costs.

[0009] By adopting the above technical solution and setting a top groove, the fixed block and the reinforcement can be connected at the top through the set snap-fit ​​mechanism during use, which further improves the strength of the connection and enhances the stability of the device connection.

[0010] As a preferred technical solution of this application, the assembly is provided with side connecting blocks on both sides, and the fixing block is provided with a sliding groove that matches the side connecting block. Both sets of sliding grooves are located on both sides of the connecting groove.

[0011] By adopting the above technical solution and setting the side connecting block, the contact area between the assembly and the fixing block can be further increased during use, thereby further improving the connection performance and structural strength.

[0012] As a preferred embodiment of this application, both the assembly and the reinforcement are provided with an external wrapping, the shape of which is the same as the external shape of the assembly and the reinforcement.

[0013] By adopting the above technical solution and setting an external wrapping component, the structure between the fixing block, the assembly, and the reinforcement can be supplemented when the production tolerance is large, thus avoiding instability caused by excessive gaps in the contact surface.

[0014] As a preferred technical solution of this application, both the assembly and the reinforcement have chamfered corners at their outer corners.

[0015] By adopting the above technical solution and setting chamfers, the stability of the connection can be further improved during use, and the device has a more aesthetically pleasing appearance.

[0016] As a preferred technical solution of this application, the assembly, the reinforcement, the fixing block and the fastener are all provided with an anti-corrosion coating on their exterior.

[0017] By adopting the above technical solutions, the external anti-corrosion coating can further protect the structure, reduce the possibility of rust, and further extend its service life.

[0018] As a preferred technical solution of this application, the size of the card block matches the size and shape of the card slot, and the size of the sliding groove matches the side connecting block.

[0019] By adopting the above technical solution, and by setting the size of the card block to match the size and shape of the card slot, and the size of the slide groove to match the side connecting block, the stability of the connection can be further improved.
