A support frame 2 is provided in the middle of the machine base 1, and a longitudinal drive mechanism 3 is provided on the support frame 2. The rivet distribution mechanism 4 is provided on both sides of the support frame 2 for distributing rivets to the lower feeding mechanism 5. The lower feeding mechanism 5 is provided on the lower side of the support frame 2 for distributing rivets to the lower riveting die base 8. At the same time, the lower feeding mechanism 5 includes multiple guides 55 of different sizes, which are used to adapt to rivets of different sizes; the upper riveting die 6 is set at the upper end of the support frame 2, the lower riveting die base 8 is set at the lower end of the support frame 2, the lower riveting die base 8 is used to set the lower die head 762, and the lower die head replacement mechanism 7 is set on the longitudinal drive mechanism 3. The longitudinal drive mechanism 3 can drive the lower die head replacement mechanism 7 to move longitudinally, and the lower die head replacement mechanism 7 is used to replace the lower die head 762 on the lower riveting die base 8.

[0029] In this application, the lower feeding mechanism 5 uses guides 55 of different sizes to accommodate rivets of different sizes. The lower feeding mechanism 5 distributes the rivets directly above the lower riveting die base 8. The lower die head 762 that matches the rivet can be selected by the lower die head changing mechanism 7. The rivet is then fed into the lower die head 762. The upper riveting die 6 moves the upper die head that matches the lower die head 762 directly above the lower die head 762. The product to be riveted is moved to the upper side of the lower riveting die base 8. The upper riveting die 6 provides power to rivet the rivet onto the product. Thus, different sizes of rivets and their corresponding lower dies 762 can be selected according to diverse product requirements, which can greatly improve the flexibility of the riveting processing device during use to adapt to diverse products.

[0030] In some embodiments, the riveting apparatus further includes a control cabinet (not shown), a control panel 11, and an upper feeding mechanism 9. The control cabinet is located inside the lower side of the machine base 1, and the control panel 11 is located on the side of the machine base 1. The control cabinet is electrically connected to the control panel 11. The control panel 11 is used to set the control parameters of the control cabinet. The control cabinet is electrically connected to the upper feeding mechanism 9, the rivet distribution mechanism 4, the lower feeding mechanism 5, the upper riveting die 6, the lower die head replacement mechanism 7, and the lower riveting die base 8, and is used to control the operation of the upper feeding mechanism 9, the rivet distribution mechanism 4, the lower feeding mechanism 5, the upper riveting die 6, the lower die head replacement mechanism 7, and the lower riveting die base 8. Those skilled in the art can conventionally select the machine base 1, control cabinet, control panel 11, upper feeding mechanism 9, rivet distribution mechanism 4, upper riveting die 6, and lower riveting die base 8 as needed. The upper feeding mechanism 9 is mounted on the longitudinal drive mechanism 3. The longitudinal drive mechanism 3 can drive the upper feeding mechanism 9 to move longitudinally. When riveting the product, the rivets can be distributed to the upper feeding mechanism 9 by the rivet distribution mechanism 4, and the rivets are picked up by the upper riveting die 6 and its upper die head for riveting. The upper riveting die 6 is equipped with an upper die head, which aligns with the lower die head 762 to rivet the rivet onto the product. Alternatively, the rivets can be distributed to the lower die head 762 of the lower riveting die base 8 by the rivet distribution mechanism 4, and then riveted by the upper riveting die 6.

[0031] In some embodiments, such as Figure 3 and Figure 4 As shown, the lower feeding mechanism 5 includes a first mounting base 51, which is horizontally arranged and fixed to the support frame 2. A second mounting base 52 and a horizontal driving mechanism 53 are arranged on the outer side of the first mounting base 51. The horizontal driving mechanism 53 is used to drive the second mounting base 52 to move horizontally. The guide member 55 is arranged on the second mounting base 52. The horizontal driving mechanism 53 is a magnetically coupled rodless cylinder, which includes a first slide table 531 and a first guide rail 532. The second mounting base 52 is disposed on the first slide table 531, and the first guide rail 532 is horizontally fixed to the first mounting base 51. The first slide table 531 can drive the second mounting base 52 to move horizontally along the first guide rail 532. In this application, the accuracy of the lower feeding mechanism 5 can be improved by using a magnetically coupled rodless cylinder, thereby accurately moving the rivet directly above the riveting die base 8.

[0032] In some embodiments, such as Figure 3 and Figure 4 As shown, a cable chain 54 is provided on the upper side of the first mounting base 51. The first end of the cable chain 54 is fixed to the first mounting base 51, and the second end of the cable chain 54 is fixed to the second mounting base 52. The first and second ends of the cable chain 54 are arranged diagonally. This further ensures the stability of the lateral movement of the second mounting base 52.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, a support member 56 is provided on the second mounting base 52, and a third mounting base 57 is provided on the upper surface of the support member 56. A first drive mechanism 58 and a slide rail 584 are provided on the third mounting base 57. The slide rail 584 is longitudinally arranged and connected to a second slide table 585. The first drive mechanism 58 is connected to the second slide table 585 and is used to drive the second slide table 585 to move longitudinally along the slide rail 584. Multiple guide members 55 are provided on the second slide table 585 to guide the rivets. Each guide member 55 corresponds to a type of rivet. After the guide member 55 moves to directly above the lower die head 762, the rivet inside the guide member 55 remains inside the lower die head 762. Then the guide member 55 is removed. There are four guide members 55, each corresponding to one of four different types of rivets, thereby improving the flexibility of the riveting device to adapt to diverse product needs.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, the first drive mechanism 58 includes a first motor 581, a first lead screw 582, and a first fixed base 583. The first lead screw 582 is connected to the first motor 581, the first fixed base 583 is screwed to the first lead screw 582, and the first fixed base 583 is fixedly connected to the second slide 585. The rotation of the first motor 581 drives the first lead screw 582 to rotate, causing the first fixed base 583 and the second slide 585 to move longitudinally. This adjusts the correspondence between the guide member 55 and the lower die head 762, moving guide members 55 of different models onto the lower die head 762. This improves the stability and accuracy of the movement of the second slide 585, ensuring that the rivet can be accurately moved to the top of the riveting lower die base 8.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, a fixing rod 59 is also provided on the third mounting base 57, and a detection unit 591 is provided on the fixing rod 59. The detection unit 591 is used to detect the moving speed and / or position of the first fixing base 583. The detection unit 591 can be a photoelectric sensor or a speed sensor, etc. Through the detection unit 591, the moving speed and position of the first fixing base 583 and the second slide 585 on it can be detected, thereby enabling precise control of the moving position of the rivet as needed.

[0036] In some embodiments, such as Figure 3 and Figure 4 As shown, a cover plate 592 is also provided on the third mounting base 57, and the cover plate 592 is located on the upper side of the detection unit 591. The cover plate 592 serves to protect the detection unit 591.

[0037] In some embodiments, the longitudinal drive mechanism 3 may be a combination of a linear motor or a telescopic rod 773 and a slider, etc. The lower die head replacement mechanism 7 is disposed on the longitudinal drive mechanism 3, and the longitudinal drive mechanism 3 may drive the lower die head replacement mechanism 7 to move longitudinally.

[0038] In some embodiments, such as Figure 5 and Figure 6 As shown, the lower mold head replacement mechanism 7 includes a drive mechanism fixing seat 79, which is mounted on the longitudinal drive mechanism 3. A second drive mechanism 73 is mounted on the drive mechanism fixing seat. The second drive mechanism 73 is connected to a vertical slide plate 75. The second drive mechanism 73 can drive the vertical slide plate 75 to move vertically. A vertical guide rail 72 is mounted on the vertical slide plate 75. Multiple vertical guide rails 72 are mounted at intervals on the vertical slide plate 75. Each vertical guide rail 72 is connected to a fixing block 74. The fixing block 74 is connected to a connecting plate 78. The connecting plate 78 is connected to the longitudinal drive mechanism 3. A mold head storage plate 76 is mounted at the lower end of the vertical slide plate 75. The mold head storage plate 76 has multiple placement holes 761, which can be used to place the corresponding lower mold head 762. In application, the vertical slide plate 75 is driven by the second drive mechanism 73. The vertical slide plate 75 moves the die head storage plate 76, thereby moving the lower die head 762 on the die head storage plate 76 to the riveting lower die base 8, aligning the lower die head on the die head storage plate 76 with the mounting hole on the riveting lower die base 8. The required lower die head 762 is placed in the mounting hole of the riveting lower die base 8, and finally the riveting lower die base 8 locks the lower die head 762 onto the riveting lower die base 8. This greatly improves the versatility and flexibility of the device, enabling it to easily handle rivets and riveting requirements of different specifications and materials, and reducing the time and cost of changing dies.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, the lower die head replacement mechanism 7 also includes a protective cover 71, which is disposed inside the second drive mechanism 73. The protective cover 71 is used to protect the second drive mechanism 73.

[0040] In some embodiments, such as Figure 5 and Figure 6As shown, the second drive mechanism 73 includes a second motor 731, a second lead screw 732, and a connecting seat 733. The second motor 731 is fixed on the drive mechanism mounting base 79. One end of the second lead screw 732 is connected to the second motor 731. The connecting seat 733 is sleeved around the second lead screw 732, screwed to the second lead screw 732, and fixedly connected to the vertical slide plate 75. The second motor 731 can drive the second lead screw 732 to rotate, thereby driving the connecting seat 733 and the vertical slide plate 75 to move vertically. This improves the stability and accuracy of the movement of the connecting seat 733, thus accurately moving the lower die head 762 directly above the riveting lower die base 8.

[0041] In some embodiments, such as Figure 5 and Figure 6 As shown, a horizontal mounting base 77 is also provided at the lower end of the vertical slide plate 75. A second fixed base 771, a movable base 772, and a telescopic rod 773 are provided on the horizontal mounting base 77. The second fixed base 771 is fixed to the horizontal mounting base 77, and the movable base 772 is adapted to the second fixed base 771. One end of the telescopic rod 773 is fixed to the vertical slide plate 75, and the other end is connected to the movable base 772, which can drive the movable base 772 to move laterally relative to the second fixed base 771. The movable base 772 is connected to the die head storage plate 76. This improves the stability and accuracy of the movement of the movable base 772, thereby accurately moving the lower die head 762 onto the die holder 8.

[0042] In some embodiments, such as Figure 5 and Figure 6 As shown, a detection unit 591 is also provided on the drive mechanism mounting base 79. The detection unit 591 is used to detect the moving speed and / or position of the vertical slide plate 75.

[0043] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, a locking hole 763 is provided at the die head storage plate 76. The locking hole 763 is perpendicular to the die head storage plate 76. A steel ball 764 and a spring 765 are provided in the locking hole 763. An arc-shaped groove 766 adapted to the steel ball 764 is provided on the periphery of the lower die head 762. The spring 765 is used to lock the steel ball 764 in the arc-shaped groove 766 to lock the lower die head 762. This allows the lower die head 762 on the press-fit lower die base 8 to be easily removed and locked.

[0044] In this application, the lower die holder 8 has mounting holes that fit the lower die head 762. The lower die holder 8 can lock and unlock the lower die head 762 in the mounting holes. When the lower die head 762 needs to be replaced, the locking hole 763 on the die head storage plate 76 moves to the position corresponding to the mounting hole, the lower die holder 8 unlocks the lower die head 762, and then the lower die head 762 is locked in the locking hole 763 by the steel ball 764 and the spring 765 at the locking hole 763. The second drive mechanism 73 drives the die head storage plate 76 to pull the lower die head 762 out of the lower die holder 8. This completes the process of removing the lower die head 762 from the lower die holder 8. Then, using the second drive mechanism 73 and / or the telescopic rod 773, the other lower die head 762 on the die head storage plate 76 is moved to the position corresponding to the mounting hole. The lower die head 762 is then locked in place by the press-fit lower die base 8, thus fixing it in place. The die head storage plate 76 is then removed using the second drive mechanism 73 and / or the telescopic rod 773, completing the replacement of the lower die head 762. Simultaneously with the replacement of the lower die head 762, the corresponding upper die head on the press-fit upper die 6 can also be replaced.

[0045] Therefore, in this application, by using guides of different sizes in the lower feeding mechanism, different sizes of rivets can be adapted. The lower feeding mechanism distributes the rivets directly above the lower riveting die base. The lower die head replacement mechanism can select the lower die head that matches the rivet, and then the rivet is fed into the lower die head. The upper riveting die moves the upper die head that matches the lower die head directly above the lower die head, moves the product to be riveted to the upper side of the lower riveting die base, and provides power through the upper riveting die to rivet the rivet onto the product. Thus, different sizes of rivets and their corresponding lower dies can be selected and used according to diverse product requirements, which can greatly improve the flexibility of the riveting processing device in use to adapt to diverse products.

[0046] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
