[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] An automatic riveting column device comprises a riveting machine body 1, a processing table 2 is fixedly installed on the front of the riveting machine body 1, a pressure-bearing part 3 is fixedly installed on the top of the processing table 2, a supporting column 4 is fixedly installed on the top of the processing table 2 and below the pressure-bearing part 3, a connecting plate 5 is fixedly installed on the left side of the processing table 2, a vibrating unloading tray 6 is fixedly installed on the top of the connecting plate 5, a unloading mechanism 7 is installed on the right side of the vibrating unloading tray 6 and on the front of the riveting machine body 1, a feeding table 8 is fixedly installed on the front of the riveting machine body 1 and below the processing table 2, a moving frame 9 is slidably connected to the top of the moving frame 9, and a fixing mechanism 10 is installed on the top of the moving frame 9.

[0028] In this embodiment, the implementation scenario is specifically as follows: when performing riveting stud processing on a thin plate workpiece, a plurality of studs are placed in a vibrating blanking tray 6, and then the thin plate workpiece is fixed on the top of a mobile frame 9 through a fixing mechanism 10 according to the position of the riveting hole on the thin plate workpiece, and then the mobile frame 9 is pushed so that the mobile frame 9 moves on the top of the feeding table 8, and the thin plate workpiece is moved to the bottom of the blanking mechanism 7, so that the riveting hole on the thin plate workpiece is aligned with the bottom of the blanking mechanism 7, and then, under the cooperation of the vibrating blanking tray 6 and the blanking mechanism 7, the studs are placed vertically into the riveting holes as needed, and when the studs are placed into the riveting holes , continue to push the mobile frame 9 until the stud in the riveting hole of the thin plate workpiece is located on the inner side of the pressure-bearing part 3, and then perform riveting processing through the riveting machine body 1. When the riveting machine body 1 is performing riveting processing, the pressure-bearing part 3 provides support to complete the riveting processing. During riveting, the support column 4 can reduce the pressure of the riveting machine body 1 pressing the stud down, and prevent the thin plate workpiece from being damaged due to excessive pressure on the stud, thereby improving the processing quality of the riveting column processing. The entire operation process is simple and convenient. Compared with the existing riveting column process, the utility model can improve the overall safety, production quality and production efficiency of the riveting column process through design.

[0029] It should be noted that the riveting machine body 1 and the vibrating feeding tray 6 in this solution are both prior art, so their mechanisms and working methods will not be described in detail.

[0030] First, see Figure 1-Figure 5 The pressure-bearing member 3 is composed of a limit plate 11 and a pressure block 12. The limit plate 11 is fixedly installed on the top of the processing table 2. Two groups of pressure blocks 12 are fixedly connected to the front of the limit plate 11.

When the stud is riveted with a thin plate workpiece under pressure, the bottom of the bolt abuts against the telescopic column 13, and the telescopic column 13 contracts into the spring to prevent the stud from being excessively squeezed and causing damage to the thin plate workpiece, thereby improving the processing quality of the riveting column processing;

[0031] Furthermore, in this embodiment, the specific structure of the unloading mechanism 7 is as follows:

[0032] The unloading mechanism 7 includes an unloading barrel 14, a feeding rack 15, a telescopic cylinder 16 and a material dividing block 17.

[0033] Furthermore, the interior of the discharge barrel 14 is designed to be hollow in structure, and a feed port is provided at the top of the left side of the discharge barrel 14 at a position corresponding to the feeding rack 15, and a discharge port is provided at the bottom of the discharge barrel 14. Before the rivet stud processing is performed, a plurality of studs are placed in the vibrating discharge tray 6, and the vibrating discharge tray 6 vertically transports the studs one by one to the interior of the discharge barrel 14 through the feeding rack 15 as needed, and then when the riveting hole of the thin plate workpiece is aligned with the discharge port below the discharge barrel 14, the dividing block 17 is moved out of the interior of the discharge barrel 14 through the return stroke of the telescopic cylinder 16, so that a stud entering the interior of the discharge barrel 14 vertically penetrates into the riveting hole of the thin plate workpiece, and then the thin plate workpiece is sent to the bottom of the riveting machine body 1 to complete the riveting, thereby automatically completing the operation of placing the studs, thereby improving the production quality and production efficiency of the riveting stud device;

[0034] Then, two sets of pulleys 18 are installed on the left and right sides of the bottom of the mobile frame 9, and a moving groove is opened at the top of the feeding platform 8 at a position corresponding to the pulley 18. A mounting plate 19 is installed on the front of the mobile frame 9, and a handle is fixedly installed on the front of the mounting plate 19. A stopper is fixedly installed in the middle of the front of the feeding platform 8. When the thin plate workpiece is riveted, after the thin plate workpiece is fixed, it is only necessary to push the mobile frame 9 by the handle. Under the cooperation of the pulley 18 and the moving groove, the mobile frame 9 is pushed to push the thin plate workpiece to the bottom of the unloading mechanism 7 to complete the operation of placing the studs, and then the mobile frame 9 is pushed to push the thin plate workpiece to the top of the processing table 2 to complete the riveting process, thereby improving the safety of manual operation and further improving the production efficiency of the riveting column device.

The fixing plate 21 is installed on the top of the mobile frame 9 and located on the outside of the clamping plate 20. The middle of the outer side of the clamping plate 20 is threadedly connected to the fixing plate 21 through the threaded rod 22. The left and right ends of the outer side of the clamping plate 20 are slidably connected to the fixing plate 21 through the sliding rod 23.

[0037] Finally, the splint 20 is designed in an "L"-shaped structure, and a rubber protective pad 24 is bonded to the inner side of the splint 20. The inner side of the rubber protective pad 24 is provided with anti-slip grooves. The end of the threaded rod 22 close to the splint 20 is rotatably connected to the splint 20, and the end of the threaded rod 22 away from the splint 20 is fixedly connected with a knob. When riveting columns are processed on a thin plate workpiece, the thin plate workpiece to be processed is placed between the two groups of splints 20. According to the positions of the rivet holes on the thin plate workpiece, the threaded rod 22 is rotated by turning the knob to move the positions of the two groups of splints 20 to clamp and fix the thin plate workpiece. With the cooperation of the sliding rod 23, the stability of the movement of the splint 20 and the fixing effect of the thin plate workpiece can be improved. When the splint 20 clamps and fixes the thin plate workpiece, the design of the rubber protective pad 24 can improve the firmness of the fixation of the thin plate workpiece.
