[0031] The following further describes the present utility model in conjunction with specific implementation cases and the attached Figures 1 to 7 drawings, but the present utility model is not limited to these embodiments.

[0032] Refer to Figures 1 to 7As shown in the figure, a riveting device for luggage production includes a workbench 1. There is a through cavity in the middle of the workbench 1. A seat body 2 is fixedly installed on the workbench 1, and the seat body 2 corresponds to the position of the through cavity of the workbench 1. Four moving frames 3 are arranged in the seat body 2. The four moving frames 3 are vertically and crosswise arranged in a "well" shape. A guide post 4 is placed vertically through the intersection of the four moving frames 3 from top to bottom. The guide post 4 is arranged in a hollow cylindrical shape. A driving unit for driving the four moving frames 3 to move synchronously is arranged in the middle of the seat body 2. Through the four guide posts 4, the installation of four rivets can be guided, so that the four groups of rivets slide along the corresponding guide posts 4 onto the sub-rivets 21 respectively. The four guide posts 4 limit the four groups of rivets respectively, ensuring that the assembled rivets are symmetrical and neat, without the need for subsequent rework to adjust the position of a certain rivet, and more importantly, ensuring the processing efficiency and the qualified rate of the finished product of the luggage rivets.

[0033] Mainly refer to Figures 3 to 6 As shown in the figure, the driving unit includes two connecting arms 5 fixedly installed on the inner wall of the through cavity of the workbench 1. The two connecting arms 5 are symmetrically installed on the inner wall of the through cavity of the workbench 1 in the front and back. A first cylinder 6 is fixedly installed between the two connecting arms 5. The connecting arms 5 provide support for the installation of the first cylinder 6. A second cylinder 7 is fixedly installed at the top of the first cylinder 6. A rotating shaft 8 is rotatably connected to the middle of the second cylinder 7 in the vertical direction through a bearing. The bottom end of the rotating shaft 8 is rotatably connected to the inner wall of the first cylinder 6. The top end of the rotating shaft 8 is provided with a turntable 9. A driving component is arranged on the turntable 9. The driving component includes four driving grooves 10 equidistantly arranged along the circumference on the turntable 9. The driving grooves 10 are inclinedly arranged on the turntable 9. A moving pin 11 is slidably embedded in the inner cavity of each driving groove 10. One end of a connecting rod 12 is fixedly installed at the bottom end of each moving pin 11. The other end of the connecting rod 12 is fixedly installed with a supporting plate 13. The connecting rod 12 slidably penetrates the side wall of the second cylinder 7. Among them, the supporting plate 13 supports the bottom end of the moving frame 3.

[0034] By rotating the rotating shaft 8, the turntable 9 and the four driving grooves 10 are driven to rotate synchronously, so as to drive the moving pins 11 in the corresponding inner cavities of the driving grooves 10 to move along the inner cavities of the driving grooves 10. Since the moving pins 11 and the connecting rods 12 are fixedly connected, and the connecting rods 12 slidably penetrate the side wall of the second cylinder 7, when the four moving pins 11 move, it can cause the four groups of connecting rods 12 and the supporting plates 13 to move synchronously. The supporting plate 13 moving outward causes the moving frame 3 at the corresponding position to move outward, and the supporting plate 13 moving inward causes the moving frame 3 at the corresponding position to move inward. Thus, the adjustment of the distance between the four guide posts 4 is realized.

[0035] Mainly refer to Figure 3 and Figure 7As shown, a first bevel gear 14 is fixedly mounted on the rotating shaft 8, a driving shaft 15 is penetrated and rotatably arranged on the side wall of the first cylinder 6, a second bevel gear 16 is fixedly mounted on the side of the driving shaft 15 close to the first bevel gear 14, and the second bevel gear 16 is meshingly connected with the first bevel gear 14, a motor 17 is mounted on the side wall of the first cylinder 6, and the output end of the motor 17 is connected to the driving shaft 15, and the driving shaft 15 and the second bevel gear 16 are driven to rotate by the turned-on motor 17, so as to drive the first bevel gear 14 and the rotating shaft 8 to rotate synchronously.

[0036] In addition, a limiting rod 18 is vertically and fixedly installed on the outer side wall of each mobile frame 3, and the limiting rod 18 slides through the side wall of the seat body 2; wherein, a clearance groove is opened on the side wall of the supporting plate 13, and the position of the clearance groove of the supporting plate 13 corresponds to the position of the limiting rod 18, thereby ensuring that when the mobile frame 3 moves, it can drive the limiting rod 18 to move outward and through the side wall of the seat body 2 to limit the moving direction of the mobile frame 3.

[0037] Main references Figure 2 and Figure 3 As shown, a placement component is provided at the bottom of the through cavity of the workbench 1; the placement component includes a placement table 19 fixedly installed at the bottom of the workbench 1, and the placement table 19 is provided with a through cavity from left to right, and luggage leather 20 is placed in the placement table 19, and sub-rivets 21 corresponding to the positions of the guide columns 4 are provided on the luggage leather 20, and the mother rivets are respectively placed in the adjusted inner cavities of the four groups of guide columns 4, and the mother rivets fall down along the inner cavities of the guide columns 4 to the corresponding sub-rivets 21, and pressure is applied to the mother rivets with the help of tools to prompt the mother rivets to be riveted on the sub-rivets 21, thereby realizing the riveting processing of the four groups of rivets, and under the guiding action of the four guide columns 4, the riveting of the four groups of rivets is ensured to be neat and symmetrical.

[0038] In addition, see Figure 1 and Figure 2 As shown, a base frame 22 is provided at the four corners of the bottom end of the workbench 1, and a universal wheel is installed at the bottom end of the base frame 22. The workbench 1 can be lifted off the ground through the base frame 22 so that the riveting work of bags can be carried out on the workbench 1. The setting of the universal wheel can facilitate the overall movement of the equipment.

[0039] In the existing bag rivet processing, the sub-rivet is installed on the bag leather, and the mother rivet at the top is riveted to the sub-rivet at the bottom to achieve the docking of the rivets, so as to achieve the docking installation of the mother rivet and the sub-rivet on the bag leather. This is the existing technology and will not be overly limited or redundantly described here;

[0040] It should be noted that the cylinder 24 used in this application is a commonly used self-locking cylinder on the market, and its output end can stay at any position and be locked; the motor 17 is a commonly used self-locking motor on the market with an output end that can be locked. When it stops operating, its output end can be self-locked and will not rotate under external force. Moreover, the motor 17 is a commonly used forward and reverse motor on the market, and its output end can rotate forward or backward according to the usage requirements, and it can meet the above usage requirements; there is no need to elaborate too much on the above existing components here.

[0041] The working principle of the riveting device for luggage production in this embodiment is as follows:

[0042] First, adjust the positions of the four groups of rivets to make them fit the size of the current luggage: By starting the motor 17, the drive shaft 15 and the second bevel gear 16 are driven to rotate, so as to drive the first bevel gear 14 and the rotating shaft 8 to rotate synchronously. The rotation of the rotating shaft 8 drives the turntable 9 and the four drive grooves 10 to rotate synchronously, so as to drive the moving pins 11 in the corresponding inner cavities of the drive grooves 10 to move along the inner cavities of the drive grooves 10. Since the moving pins 11 are fixedly connected to the connecting rods 12, and the connecting rods 12 slide through the side wall of the second cylinder 7, when the four moving pins 11 move, the four groups of connecting rods 12 and the supporting plate 13 can be driven to move synchronously. The supporting plate 13 moving outward drives the moving frame 3 at the corresponding position to move outward, and the supporting plate 13 moving inward drives the moving frame 3 at the corresponding position to move inward, thereby realizing the adjustment of the distance between the four groups of guide posts 4;

[0043] Put the female rivets into the inner cavities of the four groups of adjusted guide posts 4 respectively. The female rivets fall downward along the inner cavities of the guide posts 4 onto the corresponding male rivets 21. Apply pressure to the female rivets with tools to cause the female rivets to be riveted on the male rivets 21, thereby realizing the riveting process of the four groups of rivets. Under the guiding action of the four guide posts 4, it is ensured that the four groups of rivets are riveted neatly and symmetrically;

[0044] Through the four guide posts 4 of the present utility model, the installation of the four rivets can be guided, so that the four groups of rivets slide along the corresponding guide posts 4 respectively onto the male rivets 21. The four guide posts 4 respectively limit the four groups of rivets, ensuring that the rivets after assembly are symmetric and neat, eliminating the need for subsequent rework to adjust the position of a certain rivet, and further ensuring the processing efficiency and the qualified rate of the finished product of the luggage rivets. In addition, the distance between the four groups of guide posts 4 can be adjusted flexibly, and then the distance between the four groups of rivets can be adjusted flexibly. This device can adapt to the riveting processing requirements of various sizes of luggage, increasing the versatility of the riveting processing equipment. Moreover, no matter how the relative distance between the four groups of guide posts 4 is adjusted, the symmetry of the four groups of guide posts 4 after the adjustment position can be achieved, improving the accuracy of the luggage riveting processing.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model.
