Description

Technical Field

[0001] This utility model relates to the technical field of riveting connections, specifically a highly adaptable riveting device based on angle fine-tuning. Background Technology

[0002] Riveting devices have a wide range of applications in various industries, including automotive, aerospace, electronics, and furniture manufacturing. In the automotive industry, riveting devices are used to fasten components such as car bodies, chassis, and engines, improving the safety and durability of vehicles. In the aerospace industry, riveting devices are used to connect components such as aircraft fuselages, wings, and tail fins, ensuring the structural strength and safety of aircraft. In the electronics industry, riveting devices are used to fasten components such as housings and circuit boards in electronic products, improving product stability and reliability. Furthermore, riveting devices are also used in furniture manufacturing, packaging, metal structures and construction, home appliances and kitchenware, pipes and piping systems, and many other fields.

[0003] The working principle of the riveting device includes steps such as feeding, positioning, riveting, cutting, and output. The feeding system feeds the rivets into the equipment, the positioning device ensures the accurate position of the workpiece, the riveting device tightens the rivets and connects them tightly to the workpiece, the cutting device removes excess rivets, and finally the output device sends the connected workpiece out of the equipment.

[0004] Compared to traditional welding or bolting methods, riveting devices offer advantages such as simple installation, no need for preheating and cooling, time savings, and reduced labor intensity. However, in stroke-adjustable riveting processes, if the theoretical plate thickness is less than the actual plate thickness, the deformation zone of the rivet nut may not be fully compressed, leaving residual deformation force after installation. Manually adjusting the angle of the riveting device or changing the rivet gun requires more time and manpower, and it's difficult to achieve optimal results, ultimately affecting the quality of the final product.

It also ensures that the rivet nut is correctly installed at different positions and angles, avoiding installation problems caused by angular deviations. In use, this not only improves work efficiency and quality but also simplifies the operation process, reduces labor intensity, and improves processing accuracy and safety.

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-6 In this embodiment of the present invention, a highly adaptable riveting device based on angle fine-tuning is set on a mobile platform 1, including an angle adjustment mechanism. An air gun 2 is provided at the movable end of the angle adjustment mechanism. The angle adjustment mechanism includes a telescopic component and a drive component set on the mobile platform 1 to control the deflection of the telescopic component.

[0032] It also includes a transfer mechanism disposed on the mobile platform 1. When the telescopic member deflects relative to the transfer mechanism, the transfer mechanism can drive the telescopic member to perform telescopic operation.

[0033] In detail, the air gun 2 uses the plastic deformation of rivets to fix the structure together. According to the position of the screw hole, the angle of the air gun 2 needs to be adjusted. By activating the drive component, the telescopic component is deflected relative to the moving platform 1, thereby enabling fine adjustment of the position of the air gun 2. During the deflection of the telescopic component, it performs its own telescopic action, completing the precise adjustment of the angle of the air gun 2. It can also achieve multi-angle adjustment, which can better adapt to the actual thickness of the plate and ensure the smooth progress of the riveting process. At the same time, it can ensure that the rivet nut can be correctly installed in different positions and angles, avoiding installation problems caused by angle deviation, thereby improving welding efficiency and welding quality.

[0034] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The telescopic component includes a telescopic cylinder 3, and a hinge seat 12 that is rotatably connected to the mobile platform 1 is fixedly provided on one end of the telescopic cylinder 3.

[0035] It also includes a telescopic rod 4, one end of which is inserted into the telescopic cylinder 3 and its movement is controlled by a threaded pusher provided in the telescopic cylinder 3, and the other end is fixed to the air gun 2.

[0036] The drive assembly includes an electric telescopic rod 5, one end of which is hinged to the mobile platform 1, and the movable end of which is hinged to the telescopic cylinder 3.

[0037] Preferably, a cylindrical cavity is formed inside the telescopic cylinder 3, and at least one set of strip grooves 301 is formed inside the cylindrical cavity. A strip block 401 is formed on the telescopic rod 4 to slide and adapt to the strip grooves 301.

[0038] Specifically, when the cylinder rod of the electric telescopic rod 5 is extended or retracted manually, the telescopic cylinder 3 and the telescopic rod 4 are deflected relative to the moving platform 1 under the push of the electric telescopic rod 5. At the same time as the telescopic cylinder 3 deflects, the transfer mechanism on the moving platform 1 is driven by the relative movement of the telescopic cylinder 3 to perform the work of the threaded pusher. This can adjust the movement of the telescopic rod 4 relative to the telescopic cylinder 3, further improving the fit of the air gun 2 when fixing the connecting parts, thereby improving welding efficiency and welding quality.

[0039] It should be noted that when the telescopic rod 4 moves relative to the telescopic cylinder 3, the telescopic rod 4 drives the strip block 401 to move synchronously. At this time, under the restriction of the strip groove 301, the telescopic rod 4 can move linearly along the axis of the telescopic cylinder 3, and the strip block 401 always moves within the strip groove 301. While the telescopic rod 4 and the telescopic cylinder 3 are slidably connected, the telescopic rod 4 can move relative to the telescopic cylinder 3 under the action of the threaded pusher and is not affected.

[0040] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The transfer mechanism includes a first drive shaft 7 rotatably mounted on the mobile platform 1, with second gears 9 provided at both ends of the first drive shaft 7.

[0041] It also includes a toothed ring 6 symmetrically arranged on the hinge seat 12 and meshing with the second gear 9.

[0042] When the aforementioned hinge seat 12 deflects relative to the moving platform 1, the toothed ring 6 on it deflects synchronously. At this time, the toothed ring 6 meshes with the second gear 9, causing the second gear 9 to rotate, thereby driving the first transmission shaft 7 to rotate. This fulfills the requirement of the first transmission shaft 7 rotating when the electric telescopic rod 5 pushes the telescopic cylinder 3 to rotate, thus providing driving force for the threaded pusher.

[0043] Preferably, a support shaft that is rotatably connected to the hinge seat 12 is fixedly installed on the mobile platform 1, and the support shaft is arranged along the axial direction of the gear ring 6.

[0044] Preferably, the first drive shaft 7 is connected to the threaded pusher via a drive assembly disposed on the hinge seat 12.

[0045] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The threaded pusher includes a lead screw 13 rotatably mounted on the telescopic cylinder 3. One end of the lead screw 13 passes through the telescopic cylinder 3 and the hinge seat 12, and the other end is threadedly connected to the telescopic rod 4.

[0046] The transmission assembly includes a second transmission shaft 10 rotatably mounted on the hinge seat 12. The second transmission shaft 10 is connected to the first transmission shaft 7 via a first gear set 8, and the second transmission shaft 10 is connected to the lead screw 13 via a bevel gear set 11.

[0047] To elaborate, when the first drive shaft 7 rotates, it drives the second drive shaft 10 to rotate under the transmission of the first gear set 8. At this time, under the transmission of the bevel gear set 11, the lead screw 13 rotates accordingly. The rotation amplitude of the gear ring 6 is not large, which limits the speed of the second drive shaft 10. By changing the transmission ratio of the two bevel gears on the bevel gear set 11, the speed of the lead screw 13 can be adjusted. When the lead screw 13 rotates, it drives the telescopic rod 4 to move linearly along the axial direction of the telescopic cylinder 3. This allows for precise adjustment of the angle of the air gun 2, which can better adapt to the actual thickness of the plate and ensure the smooth progress of the riveting process, thereby improving welding efficiency and welding quality.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
