[0029] It should be noted that the first positioning groove 310 is designed according to the position of the stud 30 to be riveted on the thin frame 20, so that the thin frame 20 is positioned and fixed by the first positioning groove 310. In an embodiment, the riveting driving member 210 is a pneumatic cylinder, and the riveting driving member 210 drives the riveting seat 220 to move up and down. In an embodiment, in order to improve the stability of the up and down movement of the riveting seat 220, two guide rods are installed on the riveting seat 220, and two linear bearings are installed on the base 100 adjacent to the position of the riveting driving member 210, so that the two guide rods pass through the two linear bearings respectively. Further, the material preparation block 230 is arranged on the riveting seat 220 in a vertical direction, and a second positioning groove 231 is arranged on the bottom side of the material preparation block 230, wherein the structure of the second positioning groove 231 is the same as that of the first positioning groove 310, and a material insertion hole 232 in communication with the second positioning groove 231 is also arranged on the material preparation block 230 in a vertical direction. After the stud 30 is inserted into the material insertion hole 232, the riveting driving member 210 drives the riveting seat 220 to descend, first, the material preparation block 230 abuts against the positioning block 300, the second positioning groove 231 is engaged with the first positioning groove 310, and the second positioning groove 231 is spaced from the thin frame 20, at this time, the stud 30 is aligned with the pre-installed hole on the thin frame 20, as the riveting driving member 210 continues to drive the riveting seat 220 to descend, the riveting seat 220 pushes the stud 30 to descend along the material insertion hole 232, and finally the stud 30 is accurately riveted into the thin frame 20. In this way, the stud 30 can be accurately riveted into the thin frame 20, and the deformation of the thin frame 20 caused by excessive impact force can be effectively avoided.

[0030] As shown, Figure 2As shown, in one embodiment, a plurality of guide rods 240 are provided on the material block 230, and each guide rod 240 passes through the riveting seat 220 so that the material block 230 can move up and down relative to the riveting seat 220 in a vertical direction. In this way, the material block 230 is guided by each guide rod 240, so that the material block 230 can move up and down stably relative to the riveting seat 220.

[0031] like Figure 2 As shown, in one embodiment, a return spring 250 is sleeved on each guide rod 240, and the return spring 250 abuts against the material block 230 and the riveting seat 220 respectively.

[0032] Thus, when the riveting drive 210 drives the riveting seat 220 to rise, the elastic thrust of the return spring 250 reliably separates the material block 230 from the riveting seat 220, making it easier for the worker to place the stud into the insertion hole 232.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the material preparation block 230 is also provided with a positioning post 260, and the positioning block 300 is provided with a positioning hole 320. When the material preparation block 230 is fastened to the positioning block 300, the positioning post 260 is adapted to be inserted into the positioning hole 320.

[0034] It should be noted that in order to ensure that the material block 230 accurately abuts against the positioning block 300 and to prevent the thin frame 20 from being deformed due to positional deviation of the material block 230, a positioning post 260 is provided to cooperate with the positioning hole 320 to ensure that the material block 230 is accurately snapped down.

[0035] Furthermore, in one embodiment, multiple positioning posts 260 are provided, and multiple positioning holes 320 are provided, with each positioning post 260 corresponding to and aligned with each positioning hole 320. In this way, by engaging and inserting multiple positioning posts 260 with multiple positioning holes 320, accurate engagement between the second positioning groove 231 and the first positioning groove 310 is ensured.

[0036] In one embodiment, the end of the positioning post 260 away from the material preparation block 230 is provided with a tapered portion. In this way, the tapered portion ensures that the material preparation block 230 and the positioning block 300 are accurately engaged when the positioning post 260 descends.

[0037] like Figure 1 As shown, in one embodiment, the base 100 includes a base plate 110 and a support base 120. The support base 120 is disposed on the base plate 110, the riveting drive component 210 is disposed on the support base 120, and the positioning block 300 is disposed on the base plate 110.

[0038] It should be noted that the support seat 120 is installed on one side of the bottom plate 110, the riveting driving member 210 is installed on the top of the support seat 120, and the positioning block 300 is installed on the bottom plate 110 and located below the riveting driving member 210.

[0039] As shown in FIG. 1, in an embodiment, the bottom plate 110 is provided with a mounting groove 111, and the positioning block 300 is arranged in the mounting groove 111, so that the inner bottom wall of the first positioning groove 310 is flush with the surface of the bottom plate 110. Figure 1

[0040] It should be noted that in order to make the thin frame 20 square on the bottom plate 110 and avoid deformation of the thin frame 20 during processing, the mounting groove 111 is provided on the bottom plate 110, and the positioning block 300 is installed in the mounting groove 111, so that the inner bottom wall of the first positioning groove 310 is flush with the surface of the bottom plate 110.

[0041] As shown in FIG. 1, in an embodiment, the riveting assembly 200 further comprises a material pushing rod 271, a material pushing spring 272 and a material pushing screw 273, the material preparation block 230 is transversely provided with a material pushing hole 233 communicating with the material inserting hole 232, the material pushing rod 271 is arranged in the material pushing hole 233, the material pushing screw 273 is screwed in the material pushing hole 233, the material pushing spring 272 abuts against the material pushing screw 273 and the material pushing rod 271 respectively, and the material pushing spring 272 is used to push the material pushing rod 271, so that one end of the material pushing rod 271 extends into the material inserting hole 232. Figure 3 It should be noted that in order to make the columnar nail 30 remain in the material inserting hole 232, the above structure is provided to assist in fixing the columnar nail 30. Specifically, by rotating the material pushing screw 273, the compression amount of the material pushing spring 272 can be changed, so that the elastic force of the material pushing rod 271 is changed. Since one end of the material pushing rod 271 extends into the material inserting hole 232, when the columnar nail 30 is inserted into the material inserting hole 232, the columnar nail 30 is stopped by the material pushing rod 271, so that the columnar nail 30 will not automatically slide out of the material inserting hole 232. Only when the riveting seat 220 pushes the columnar nail 30, the columnar nail 30 will be riveted into the thin frame 20 along the material inserting hole 232 to complete the riveting installation.
