[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 3 As shown,

[0019] A rivet nut tapping device, characterized in that it includes a frame 2, a vibration disk 3 is fixedly connected to one side of the frame 2, a work table 4 is rotatably connected to one side of the frame 2, a first driving motor 5 is fixedly connected to the lower end of the frame 2 to drive the work table 4 to rotate, the output end of the vibration disk 3 is connected to a feeding channel 6, a discharge rack 7 is symmetrically and slidably provided on the work table 4, a discharge trough 8 is provided on the discharge rack 7, and a first push rod motor 9 is also provided on the work table 4 to drive the discharge rack 7 to move, a second push rod motor 10 is fixedly connected to the upper end of the frame 2, a third push rod motor 11 is fixedly connected to the push rod of the second push rod motor 10, a support frame 12 is fixedly connected to the push rod of the third push rod motor 11, and a row of taps 13 is provided at the lower end of the support frame 12.

[0020] In this embodiment, a large number of rivet nut column blanks are loaded into the vibration plate 3. After being vibrated and arranged by the vibration plate 3, the rivet nut column blanks enter the feeding channel 6, and then enter one of the discharge slots 8 of the discharge rack 7 along the feeding channel 6. Then, the first push rod motor 9 drives the discharge rack 7 to move, so that the remaining discharge slots 8 are also filled with rivet nut column blanks. After the discharge rack 7 on one side has finished putting the rivet nut column blanks, the first drive motor 5 drives the workbench 4 to rotate, so that the discharge rack 7 with the rivet nut column blanks put in comes under the tap 13. , the third push rod motor 11 drives the support frame 12 and the tap 13 to descend, and the rivet nut column blank is tapped. After the tapping is completed, the second push rod motor 10 drives the third push rod motor 11 and the tap 13 to retreat, so that the tapped rivet nut column blank is separated from the discharge groove 8. At the same time, the discharge frame 7 on the other side is loaded. When the tapping of the rivet nut column blank on one side is completed, the rivet nut column blank on the other side is also loaded, and it can be rotated and alternated immediately, which saves the loading time and can tap multiple rivet nut column blanks at the same time, thereby improving the efficiency.

[0021] In this embodiment, the support frame 12 is fixedly connected with a second drive motor 14, and a row of rotating blocks 15 are rotatably connected to the support frame 12. The rotating blocks 15 are sleeved with gears 16, and adjacent gears 16 are meshed. The taps 13 are fixedly connected to the lower ends of the rotating blocks 15, and the output shaft of the second drive motor 14 is connected to any rotating block 15. The second drive motor 14 drives a row of rotating blocks 15 to rotate simultaneously through the gears 16, that is, drives a row of taps 13 to rotate simultaneously for tapping.

[0022] In this embodiment, connecting rods 17 are symmetrically arranged on both sides of the workbench 4, and a fourth push rod motor 18 is fixedly connected to the connecting rod 17, and a clamping plate 19 is fixedly connected to the push rod of the fourth push rod motor 18. After the rivet nut column blank enters the discharge trough 8, the fourth push rod motor 18 drives the clamping plate 19 to move, and cooperates with the discharge rack 7 to clamp the rivet nut column blank, so that the tapping is more accurate.

[0023] In this embodiment, a coolant tank 20 is fixedly connected to the frame 2, and a plurality of nozzles 21 are provided at the lower end of the coolant tank 20. When the rivet nut blank is tapped, the coolant tank 20 sprays coolant through the nozzles 21 to cool the rivet nut blank.

[0024] In this embodiment, a collection box 22 is provided at the lower end of the frame 2, and a filter screen 23 is provided in the collection box 22. After the rivet nuts are tapped, they fall onto the filter screen 23 in the collection box 22, and the coolant remaining on the rivet nuts passes through the filter screen 23 and falls to the bottom of the collection box 22 for reuse.
