[0033] The working principle of the stamping assembly 8 is as follows: in specific applications, the rivet nut transported from the top of the conveyor belt 5 falls along the connecting frame 10 to the top of the turntable 801, and the servo motor 802 is started by an external controller, and then the turntable 801 is driven to rotate under the action of the servo motor 802. During the rotation, the turntable 801 is driven to rotate to one of the groups of auxiliary components 9, so that the auxiliary components 9 assemble the workpiece to be riveted and the rivet nut together, and at the same time, two groups of hydraulic rods 808 and punching heads 805 are started, and under the action of the hydraulic rods 808, the two groups of protrusions 807 are driven to move on the outside of the limit rod 806, and when they move to the assembled workpiece and rivet nut, the two are riveted together by the punching head 805.

[0034] In one embodiment, for the above-mentioned auxiliary component 9, the auxiliary component 9 includes a limit plate 901 installed on the top of the workbench 1, a connecting plate 902 is provided on one side of the limit plate 901, a servo motor 2 903 is provided on one side of the connecting plate 902, a turntable 1 904 is provided on the output shaft of the servo motor 2 903, a turntable 2 906 is provided on the outer side of the turntable 1 904 through a sliding belt 905, a connecting ring 907 is provided on the outer side of the sliding belt 905, and an adjuster 908 is provided on one side of the connecting ring 907; the adjuster 908 includes a placing plate 909 installed on one side of the connecting ring 907, a servo motor 3 9081 is provided on the top of the placing plate 909, a screw rod 9082 is provided on the output shaft of the servo motor 3 9081, and a screw rod 9082 is provided on the screw rod 908. 2 is provided with a sliding block 9083 on the outside, and a workpiece gripper 9084 is provided on one side of the sliding block 9083, and two groups of connecting blocks 9085 are provided on the other side of the sliding block 9083, and the connecting block 9085 is connected to the connecting rod 9086 on one side of the placement plate 909; a slider 910 is provided on the other side of the placement plate 909, and one side of the slider 910 is connected to the sliding rod 911 on one side of the connecting plate 902, so that the workpiece to be riveted can be picked up to the outside of the bayonet 804 and assembled with the rivet nut under the action of the workpiece gripper 9084, realizing the automatic assembly of the workpiece to be riveted and the rivet nut, and at the same time, the riveted product completed by punching and riveting can be removed without manual removal, reducing the direct contact between manual and mechanical operations, thereby improving the efficiency of punching and riveting.

[0035] The working principle of the auxiliary component 9 is as follows: the servo motor 2 903 is started by an external controller, and then the wheel 1 904 is driven to rotate under the action of the servo motor 2 903, and then the plate 909 is placed on the outside of the slide bar 911 with the assistance of the connecting ring 907 on the outside of the sliding belt 905 to achieve left and right translation movement, and then the regulator 908 on the outside of the placement plate 909 is moved to the specified position. It should be noted that the function of the auxiliary component 9 is to pick up the workpiece inside the workpiece placement box at the top of the workbench 1 to the outside of the bayonet 804. The first step is to assemble with the rivet nut, and the second step is to remove the riveted product completed by stamping and riveting and place it inside the finished product collection box, so that the specified position of the regulator 908 is above the workpiece placement box or the finished product collection box. After reaching the specified location, the servo motor three 9081 is started, and the sliding block 9083 is driven by the action of the servo motor three 9081 to slide on the outside of the screw rod 9082 and the connecting rod 9086. When it slides to the required height, the workpiece can be picked up or the riveted product can be removed from the outside of the bayonet 804 under the action of the workpiece gripper 9084.

[0036] It should be noted that the hydraulic rod 808 , the second servo motor 903 , and the third servo motor 9081 are respectively connected to the top or side wall of the workbench 1 .

[0037] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0038] In actual application, the staff places the rivet nut inside the vibrating feed tray 3, and drives the vibrating feed tray 3 to feed the rivet nuts one by one into the connecting frame 10 through the drop port 11 and drop to the top of the bayonet 804, and then drives the servo motor 802. Under the drive of the servo motor 802, the turntable 801 rotates, and during the rotation, the rivet nut is moved to one side of one group of auxiliary components 9. Under the action of the auxiliary component 9, the workpiece gripper 9084 is used to assemble the workpiece to be riveted to the top of the rivet nut. After the assembly is completed, the assembled rivet nut and the workpiece are fixed using two groups of abutment plates 809 under the action of the hydraulic rod 808, and the punch head 805 is started to punch and rivet it.

[0039] It should be noted that the punching principle of the punch head 805 (the driving of the punch head 805 belongs to the existing technology and will not be described in detail here) is to apply a certain pressure through the punching equipment to make the connecting parts, usually metal plates, undergo plastic deformation under the action of the mold to form stable riveted points. This connection method does not require additional fasteners such as welding or bolts, and has the advantages of high connection strength, high efficiency and low cost. The punch head 805 presses down and applies pressure on the overlapping workpieces and riveted nuts. At this time, the workpiece undergoes local plastic deformation under the control of the mold to form rivet points. Under the action of pressure, the surface of the workpiece The metal will flow to form a metal protrusion or depression, similar to the shape of a traditional rivet. This deformed area fits tightly with the surrounding plates to form a strong mechanical connection. When the pressure stops, the deformed area of ​​the riveted point cools and fixes to form a permanent connection point. The punch head 805 is then removed to complete the entire riveting process. After the riveting is completed, another set of auxiliary components 9 is used to remove the riveted finished product from the top of the bayonet 804 and place it inside the collection box. The workpiece placement box and the finished product collection box are not shown in the figure. In specific applications, they can be adaptively adjusted according to the installation position of the auxiliary component 9.

[0040] In summary, by means of the above technical solution of the present invention, the present invention has a simple structure and is easy to operate. By setting the punching assembly 8 and the auxiliary assembly 9, not only can the rivet nut be fixed on the workpiece by punching to replace the spot welding connection of the traditional technology, but also the workpiece and the nut can be fixed during the punching process to ensure stability during use. By setting the punching assembly 8, the present invention can drive the abutment plate 809 to fix the assembled rivet nut and the workpiece under the action of the hydraulic rod 808, prevent the rivet nut and the workpiece from moving due to the punching force when performing high-speed punching, and ensure stability during the punching process. By setting the auxiliary assembly 9, the present invention can pick up the workpiece to be riveted to the outside of the bayonet 804 and assemble it with the rivet nut under the action of the workpiece gripper 9084, thereby realizing the automatic assembly of the workpiece to be riveted and the rivet nut. At the same time, the riveted finished product completed by punching and riveting can also be removed without manual removal, reducing the direct contact between manual and mechanical operations, thereby improving the efficiency during punching and riveting.
