Description

Technical Field

[0001] The utility model relates to the technical field of riveting, in particular to a riveting device for automobile parts. Background Technique

[0002] Riveting and welding are two well-known methods in the mechanical field for connecting multiple parts. Among them, riveting is a method of using axial force to thicken the nail rod in the rivet hole of the part and form a nail head to connect multiple parts.

[0003] After retrieval, a riveting device for automobile parts disclosed in CN208592311U, for example, includes a riveting machine and a positioning mechanism. The riveting machine is located above the positioning mechanism. The positioning mechanism includes a base. There is a groove on the base. A positioning block and a spring are arranged in the groove. The positioning block is slidably connected in the groove. One end of the spring is fixedly connected to the positioning block, and the other end of the spring is fixedly connected to the side wall of the groove. A resisting plate is arranged on the base. The resisting plate is slidably connected to the base, and a pressing mechanism for pressing the resisting plate is arranged on the base.

[0004] The above technical solution has certain beneficial effects. However, in the actual use process, the positioning block is pushed by the spring to squeeze and fix the rotating shaft. However, during riveting, the output end of the riveting machine will rotate and press down for riveting treatment. During this process, the rotating shaft will be shaken, and a strong force from the spring is required to act. However, it is impossible for manual operation to quickly adjust the positioning block. When the spring force is small, the rotating shaft is likely to shake, resulting in an irregular riveting surface and affecting the riveting quality. Therefore, we propose a riveting device for automobile parts. Content of the Utility Model

[0029] It is convenient for cooperation between the fixed positioning holes 10 and the connection positioning mechanisms 11, so that the movable mounting base block 3 can be stably located on the top of the riveting machine body 1 for use, improving the use stability and facilitating operation.

[0030] In another embodiment, as Figure 2 and Figure 3 shown, the inner side of the fixed through hole 7 and the outer side of the fixed positioning post 2 are slidably fitted to each other.

[0031] It is convenient for the movable mounting base block 3 to be stably sleeved on the outer surface of the fixed positioning post 2 under the action of the fixed through hole 7, and the operation is convenient.

[0032] In another embodiment, as Figure 3 shown, the adjusting and fastening mechanism 9 includes a movable adjusting threaded rod 12. One end of the movable adjusting threaded rod 12 is fixedly connected with a fixed connection block 13, and the other end of the movable adjusting threaded rod 12 is fixedly connected with a connection rotating block 16. An activity sleeve block 14 is movably sleeved on the outer surface of the fixed connection block 13, and one side of the activity sleeve block 14 away from the movable adjusting threaded rod 12 is fixedly connected with a fixed connection extrusion block 15.

[0033] It is convenient to rotate the connection rotating block 16, drive the movable adjusting threaded rod 12 and the fixed connection block 13 to rotate, so that the movable adjusting threaded rod 12 rotates and moves inside the movable mounting base block 3, pushes the fixed connection block 13, and further drives the activity sleeve block 14 and the fixed connection extrusion block 15 to move, so that the fixed connection extrusion block 15 can move inside the placement groove 8, and the fixed connection extrusion block 15 can move and extrude the rotating shaft inside the placement groove 8, and the operation is convenient.

[0034] In another embodiment, as Figure 3 shown, fixed guiding and limiting blocks 17 are symmetrically provided on the top of the movable mounting base block 3, and the inner sides of the fixed guiding and limiting blocks 17 and the two sides of the bottom of the movable limiting block 5 are slidably fitted to each other.
