[0036] The upper support plate 7 has a through hole extending through its thickness direction to accommodate the sleeve 2 during riveting. The upper riveting device 4 includes an upper base plate 18, an upper pad plate 19, and an upper support plate 20; the upper base plate 18 and the upper support plate 20 are connected by a fifth guide post 23, and the upper base plate 18 and the upper pad plate 19 are connected by a sixth guide post 24 and a seventh guide post 25, and a second base 38 is fixedly disposed on the surface of the upper base plate 18; an eighth guide post 39 is fixedly disposed on the surface of the upper pad plate 19 near the upper base plate 18, and the surface of the second base 38 has a groove corresponding to the eighth guide post 39, and a third spring 40 is disposed on the outer side of the eighth guide post 39, which contacts the second base 38 and the upper pad plate 19, and the third spring 40 causes the upper pad plate to close. The upper riveting device 4 is provided with a riveting head 21, and the riveting head 21 is fixedly disposed on the surface of the upper support plate 20. When riveting, the riveting head 21 contacts the sleeve and pushes the sleeve downward for riveting.

[0037] Furthermore, positioning guide posts 22 are provided on both sides of the riveting head 21 for positioning during riveting. The lower support plate 7 has positioning holes 42 that match the positioning guide posts 22. A fourth flat portion 41 is provided on the inner wall of the through hole of the lower support plate 7 to facilitate determining the orientation of the sleeve when it is placed.

[0038] The working process of the bracket plate sleeve riveting device involved in this utility model is as follows: First, the part of the bracket plate 1 with holes is placed between the lower riveting module 9 and the upper support plate 7. Then, the riveting block 15 is moved downward so that the second flat part 28 contacts the flat part inside the hole on the bracket plate 1, thereby allowing the riveting block 15 to pass through the bracket plate 1. At this time, the upper part of the riveting block 15 is located in the through hole of the upper support plate 7, and the second flat part 28 matches the fourth flat part 41. The sleeve 2 is placed in the through hole of the upper support plate 7, at which time the first flat part 34 matches the fourth flat part 41. At this time, the sleeve recess 37 on the sleeve 2 matches the riveting block protrusion 27. At this time, the upper riveting device 4 presses down, the riveting head 21 contacts the sleeve 2 and applies downward pressure, the inclined part 36 of the sleeve contacts the inner wall of the upper hole of the bracket plate 1, and continues to apply downward pressure to fix the sleeve 2 and the bracket plate 1 together. The presence of the protrusion allows the two to be firmly connected. The sleeve flange 33 of the sleeve 2 stops when it contacts the surface of the bracket plate 1.
