[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 7 As shown, this utility model provides:

[0025] An automatic riveting device for automotive sunroof guide rails includes a base 1. A mounting seat 2 and a riveting seat 21 are respectively provided on the top of the base 1. A sliding seat 5 is movably provided on the top of the riveting seat 21. A connector 7 and a guide rail body 8 are placed on the top of the sliding seat 5. Multiple riveting holes are opened inside the guide rail body 8, and rivets 10 are provided inside the riveting holes. A support frame 4 is also provided on the top of the riveting seat 21. A riveting assembly for riveting the connector 7 and the guide rail body 8 is provided inside the support frame 4. A motor 3 is provided on the top of the mounting seat 2, and an intermittent rotation assembly is provided on the output shaft of the motor 3.

[0026] When the rivet 10 is moved to the position below the riveting head 17 by the sliding seat 5, it stops moving. At this time, the riveting head 17 moves downward to squeeze the rivet, thereby completing the riveting work of the connector 7 and the guide rail body 8. Through continuous automatic riveting, the riveting work can be completed without readjusting the position of the connector 7 and the guide rail body 8.

[0027] like Figure 6 As shown, the intermittent rotation assembly includes a turntable 18 connected to the output shaft of the motor 3. A contact rod 19 is provided on one outer periphery of the turntable 18. A rotating rod 12 is also provided on the central shaft of one side of the turntable 18. A half gear 15 is provided at one end of the rotating rod 12. A shaped block 20 that works in cooperation with the contact rod 19 is rotatably provided on the side wall of the mounting base 2.

[0028] The contact rod 19 rotates in conjunction with the shaped block 20, causing the shaped block 20 to rotate 60 degrees and then stop rotating for a period of time. At the same time, the screw 13 on the outside of the shaped block 20 will also rotate intermittently, thereby causing the sliding seat 5 to move intermittently. That is, when the sliding seat 5 moves the rivet 10 to below the riveting head 17, it stops moving. At this time, the riveting head 17 moves downward to squeeze the rivet, thereby completing the riveting work of the connector 7 and the guide rail body 8. Through continuous automatic riveting, the riveting work can be completed without readjusting the positions of the connector 7 and the guide rail body 8.

[0029] like Figure 5 As shown, the riveting assembly includes a toothed ring 14 that meshes with the half gear 15. A lower pressure plate 16 is provided at the bottom of the toothed ring 14, and a riveting pressure head 17 that works in conjunction with the rivet 10 is provided at the bottom of the lower pressure plate 16.

[0030] The rotation of the rotating rod 12 drives the half gear 15 to rotate, and the half gear 15, in conjunction with the gear ring 14, drives the lower pressure plate 16 and the riveting head 17 to move vertically back and forth. The riveting head 17 moves downward to complete the riveting work between the connector 7 and the guide rail body 8.

[0031] like Figure 5 As shown, the support frame 4 is provided with symmetrical limiting telescopic rods 11 inside, and the telescopic ends of the two limiting telescopic rods 11 are connected to the top of the lower pressure plate 16.

[0032] The limiting telescopic rod 11 is used to prevent the toothed ring 14 on the top of the lower pressure plate 16 from disengaging from the half gear 15, which would prevent the riveting of the connector 7 and the guide rail body 8.

[0033] like Figure 3 As shown, positioning elements 9 are provided on both sides of the top of the sliding seat 5, and connecting elements 7 and guide rail body 8 are movably arranged on the outside of the positioning elements 9 in sequence.

[0034] The positioning element 9 ensures that the connector 7 and the guide rail body 8 will not shift during riveting, and also facilitates subsequent riveting work.

[0035] like Figure 1 and Figure 2 As shown, a screw 13 is provided on the central shaft of one side of the irregular block 20, and a threaded groove is provided inside the sliding seat 5 to work with the screw 13. Limiting blocks 6 are provided on both sides of the bottom of the sliding seat 5, and a limiting groove is provided on the top of the riveting seat 21 for the limiting blocks 6 to move.

[0036] The limiting block 6 slides within the limiting groove to prevent the sliding seat 5 from shifting position during movement.

[0037] Working principle: When riveting the connector 7 and the guide rail body 8, first place the connector 7 and the guide rail body 8 on the positioning part 9 on the top of the riveting seat 21. The threaded groove on the positioning part 9, in conjunction with the nut, ensures that the connector 7 and the guide rail body 8 do not shift during riveting, facilitating subsequent riveting work. Then, place the rivet 10 in the riveting hole inside the guide rail body 8. Next, start the motor 3 to drive the turntable 18 to rotate. At the same time, the rotating rod 12 and the abutment rod 19 on one side of the turntable 18 will also rotate. Through the abutment rod 19 cooperating with the rotation of the irregular block 20, the irregular block 20 will stop after rotating 60 degrees. After rotating for a period of time, the screw 13 on the outside of the irregular block 20 will also rotate intermittently, thereby causing the sliding seat 5 to move intermittently. When the rotating rod 12 rotates, it will drive the half gear 15 to rotate. Then, the half gear 15, in conjunction with the gear ring 14, can drive the lower pressure plate 16 and the riveting pressure head 17 to move vertically back and forth. That is, when the sliding seat 5 drives the rivet 10 to move below the riveting pressure head 17, it stops moving. At this time, the riveting pressure head 17 moves downward to squeeze the rivet, thereby completing the riveting work of the connector 7 and the guide rail body 8. Through continuous automatic riveting, the riveting work can be completed without readjusting the position of the connector 7 and the guide rail body 8.
