Description
Technical Field
[0001] This utility model relates to the technical field of bushing riveting, and in particular to a bushing riveting machine. Background Technology
[0002] Some automotive parts (hereinafter referred to as workpieces) require riveting bushings during the production process. Generally, bushings are riveted to workpieces using a riveting device for automotive seat frame bushings disclosed in utility model patent CN210907941U and a bushing riveting device disclosed in invention patent CN115972602B.
[0003] However, during use, it was found that the existing riveting equipment has a relatively simple mechanism, requiring workers to repeatedly feed the workpiece and bushing, then rivet them, and then remove them. This is time-consuming and labor-intensive, affecting production efficiency and resulting in poor practicality. Therefore, it is urgent to improve the existing bushing riveting machine. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a bushing riveting machine that uses a feeding mechanism to transport the bushing to a limiting mechanism, then the limiting mechanism rotates, and the operator places the workpiece on the limiting mechanism so that the bushing passes through the workpiece. The limiting mechanism then continues to rotate, and the bushing is riveted to the workpiece by a riveting mechanism. After the limiting mechanism rotates again, the workpiece with the riveted bushing is removed by a discharging mechanism, thereby improving the practicality of the equipment.
[0005] The present invention relates to a bushing riveting machine, which includes a feeding mechanism; it also includes a limiting mechanism, a riveting mechanism and a discharging mechanism, wherein the feeding mechanism, the riveting mechanism and the discharging mechanism are all mounted on the limiting mechanism;
[0006] The feeding mechanism feeds the bushing, the limiting mechanism limits the bushing and the workpiece, the riveting mechanism rivets the bushing, and the unloading mechanism unloads the workpiece.
[0007] The bushing is fed to the limiting mechanism by the feeding mechanism. The limiting mechanism then rotates, and the operator places the workpiece on the limiting mechanism so that the bushing passes through the workpiece. The limiting mechanism continues to rotate, and the bushing is riveted to the workpiece by the riveting mechanism. The limiting mechanism then rotates again, and the workpiece with the riveted bushing is removed by the unloading mechanism, thereby improving the practicality of the equipment.
[0008] Preferably, the limiting mechanism includes a worktable, a rotary table, multiple sets of bases, and multiple sets of support molds. The rotary table is rotatably mounted on top of the worktable, and a drive motor is installed inside the worktable. The output shaft of the drive motor is connected to the bottom of the rotary table. Multiple sets of bases are all mounted on top of the rotary table, and multiple sets of springs are respectively mounted on top of the multiple sets of bases. Multiple sets of support molds are slidably mounted on top of the multiple sets of bases, and multiple sets of springs are provided between the multiple sets of bases and the multiple sets of support molds. The bushing and workpiece are supported and limited by the support molds. Then, the rotary table is rotated by the drive motor inside the worktable to adjust the position of the workpiece and bushing, thereby improving the practicality of the equipment.
[0009] Preferably, the feeding mechanism includes a vibrating feeding plate, a lifting cylinder, and bushing grippers, all of which are mounted on a worktable. The vibrating feeding plate conveys the bushings and arranges them neatly. Then, the lifting cylinder lifts a group of bushings, and the bushing grippers clamp the bushings lifted by the lifting cylinder and move them onto the support mold, thus completing the bushing feeding and improving the convenience of the equipment.
[0010] Preferably, the riveting mechanism includes a riveting device, a riveting die, and a second spring. The riveting device is installed on the top of the workbench, the riveting die is installed on the riveting device, and the second spring is installed at the bottom of the riveting die. By operating the riveting device, the riveting die moves downward and punches the bushing, riveting the bushing to the workpiece. At the same time, the elasticity of the second spring and the first spring reduces the impact force between the riveting die and the supporting die, thereby improving the practicality of the equipment.
[0011] Preferably, the bottom of the riveting die is provided with a guide post, and the supporting die is provided with a guide hole; when the riveting die descends, the guide post is inserted into the guide hole of the supporting die to guide the riveting die, ensuring that the riveting die accurately presses the bushing, thereby improving the practicality of the equipment.
[0012] Preferably, the unloading mechanism includes unloading grippers and a discharge plate. The unloading grippers are installed on the top of the workbench, and the discharge plate is installed at the rear of the workbench. The unloading grippers clamp the workpiece with the riveted bushing, and then the unloading grippers place the workpiece with the riveted bushing on the discharge plate, and discharge it through the discharge plate, thereby improving the practicality of the equipment.
[0013] Preferably, the vibrating feeder has a dual-output structure and the bushing gripper has a dual-clamping structure; a set of bushings consists of two bushings, which are simultaneously arranged neatly by the vibrating feeder, and then simultaneously lifted by the lifting cylinder. After that, the two bushings lifted by the lifting cylinder are simultaneously placed on the support mold by the bushing gripper, thereby improving the practicality of the equipment.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the bushing is conveyed to the limiting mechanism by the feeding mechanism, then the limiting mechanism rotates, and the worker places the workpiece on the limiting mechanism so that the bushing passes through the workpiece. Then the limiting mechanism continues to rotate, and the bushing is riveted to the workpiece by the riveting mechanism. Then the limiting mechanism rotates again, and the workpiece with the riveted bushing is removed by the unloading mechanism, thereby improving the practicality of the equipment.

[0026] like Figures 1 to 9 As shown, a bushing riveting machine includes a feeding mechanism; it also includes a limiting mechanism, a riveting mechanism, and a discharging mechanism, all of which are mounted on the limiting mechanism.
[0027] The feeding mechanism feeds the bushing, the limiting mechanism limits the bushing and the workpiece, the riveting mechanism rivets the bushing, and the unloading mechanism unloads the workpiece.
[0028] The limiting mechanism includes a worktable 1, a rotary table 2, multiple sets of bases 3 and multiple sets of support molds 4. The rotary table 2 is rotatably mounted on the top of the worktable 1, and a drive motor is installed inside the worktable 1. The output shaft of the drive motor is connected to the bottom of the rotary table 2. Multiple sets of bases 3 are all mounted on the top of the rotary table 2. Multiple sets of springs 5 are respectively mounted on the top of the multiple sets of bases 3. Multiple sets of support molds 4 are slidably mounted on the top of the multiple sets of bases 3, and multiple sets of springs 5 are provided between the multiple sets of bases 3 and the multiple sets of support molds 4.
[0029] The feeding mechanism includes a vibrating feeding plate 6, a lifting cylinder 7, and a bushing gripper 8, all of which are mounted on the worktable 1.

The riveting device 9 is installed on the top of the workbench 1, the riveting mold 10 is installed on the riveting device 9, and the second spring 11 is installed on the bottom of the riveting mold 10.
[0031] The bottom of the riveting mold 10 is provided with a guide post 12, and the support mold 4 is provided with a guide hole;
[0032] The unloading mechanism includes an unloading gripper 13 and a discharge plate 14. The unloading gripper 13 is installed on the top of the workbench 1, and the discharge plate 14 is installed at the rear of the workbench 1.
