In the riveting system 2000, the first end plate 110 and the second end plate 120 are riveted at the same time, so that the efficiency of pressure riveting is improved; the two ends are riveted simultaneously, so that the phenomenon of poor riveting effect caused by the fact that one end cannot be fixed when being riveted is avoided, and the riveting strength is improved;
preferably, the clamping assembly 200 further comprises: a sliding plate 250 connected to the conveying assembly 300; a first guide rail 230 disposed on the sliding plate 250 along a first direction, the first clamping member 210 being fixedly disposed on the sliding plate 250, the second clamping member 220 being connected to the first guide rail 230, and the second clamping member 220 being slidable along the first direction with respect to the guide rail; a first driving cylinder 240 for driving the second clamping member 220 to slide relative to the first guide rail 230; specifically, the second clamping member 220 slides relative to the first guide rail 230, so as to realize the movement of the second clamping along the first direction, further change the distance between the second clamping member and the first clamping member 210, and finally realize the clamping and releasing of the sleeve 600. Further, the first clamping member 210 includes a first clamping bar 211 and a first sliding bar 212 which are fixedly connected, the first clamping portion 213 is disposed on the first clamping bar 211, and the first sliding bar 212 is fixed on the sliding plate 250; the second clamping member 220 comprises a second clamping rod 221 and a second sliding rod 222 which are fixedly connected, the second clamping part 223 is arranged on the second clamping rod 221, and the second sliding rod 222 is slidably connected with the first guide rail 230; when the second clamping member 220 slides to the position where the first sliding rod 212 abuts against the second sliding rod 222, the second clamping member 220 can be restricted from sliding further, and thus the second clamping member can also function as a protective sleeve 600.
The delivery assembly 300 includes: a fixed plate 310, wherein a second guide rail 320 is arranged on the fixed plate 310, the second guide rail 320 is arranged along a second direction, and the sliding plate 250 is slidably arranged on the second guide rail 320; a second driving cylinder 330 for driving the sliding plate 250 to slide with respect to the second guide rail 320.
Specifically, the sliding plate 250 slides relative to the fixed plate 310, so that the first clamping member 210 and the second clamping member 220 on the sliding plate 250 drive the sleeve 600 to move together along the second direction, thereby conveying the sleeve 600 to the rivet 100.
Further, a first stopper 311 and a second stopper 312 are disposed on the fixed plate 310, and the first stopper 311 and the second stopper 312 are respectively disposed at front and rear ends of the sliding plate 250.

The elastic piece 224 is provided to protect the sleeve 600. Specifically, when the second clamping member 220 moves to just abut against the sleeve 600, it is difficult to stop the movement instantly, and the movement tends to continue for a distance, and if the elastic piece 224 is not provided, the second clamping member 220 is likely to continue to move, which may cause the sleeve 600 to be damaged; if the elastic piece 224 is provided, the movement of the second clamping member 220 is just absorbed by the deformation of the second clamping member 220, and the sleeve 600 is not damaged.

Specifically, since the sleeve 600 cannot be accurately positioned at the riveting position, the present embodiment provides a fixed stroke of each transportation of the transportation assembly 300, so that the position after transportation is necessarily a preset position as long as the sleeve 600 is positioned before transportation. Before conveying, the positioning column 510 is positioned between the first clamping part 213 and the second clamping part 223, and then the sleeve 600 is positioned between the first clamping part 213 and the second clamping part 223 to realize positioning; then, the second clamping portion 223 moves to clamp the sleeve 600, the rear positioning column 510 moves along the third direction to withdraw from the sleeve 600 after clamping the sleeve 600, so that the sleeve 600 can move along the second direction, and finally the sleeve 600 is conveyed to the rivet 100 under the driving of the conveying assembly 300. After riveting, the second clamping portion 223 releases the sleeve 600, the conveying assembly 300 drives the clamping assembly 200 to withdraw from the riveting member 100, and the positioning column 510 moves along the third direction to reach between the first clamping portion 213 and the second clamping portion 223 for positioning, clamping and conveying the sleeve 600 next time.

The guide surface 511 is provided to correct the positional error of the sleeve 600 with a guiding function when the positioning post 510 is inserted into the sleeve 600, thereby achieving accurate positioning. At the same time, the guiding surface 511 also makes the insertion of the positioning post 510 into the sleeve 600 smoother.
Preferably, the riveting system 2000 further comprises: the power mechanism 430 is disposed on one side of the first squeeze riveting head 410 away from the second squeeze riveting head 420, and is configured to drive the first squeeze riveting head 410 to move towards or away from the first through hole 111;

The notches 130 are uniformly arranged, so that the sizes of the deformation parts 131 are consistent, the deformation quantity is consistent, and the effect that the riveting strength of each part is the same is finally achieved.
Preferably, a deformation portion 131 is disposed between any two adjacent notches 130, and the movement of the first squeeze riveting head 410/the second squeeze riveting head 420 toward the sleeve 600 can drive the deformation portion 131 to bend toward the sleeve 600.
Specifically, the portion of the first end plate 110/the second end plate 120 between two adjacent notches 130 is deformed (i.e., the deformation portion 131), and the deformation portion 131 is bent (or has other various forms of deformation, where bending is understood as a generalized deformation) along with the movement of the first riveting head 410/the second riveting head 420, so that the deformation portion 131 is integrally coupled with the sleeve 600 to realize riveting.
Preferably, the first squeeze head 410 and the second squeeze head 420 have a guide portion at one end close to the sleeve 600, the outer diameter of the guide portion gradually decreases from the first squeeze head 410/the second squeeze head 420 toward the sleeve 600 to form a guide slope 421, and the minimum outer diameter of the guide portion is smaller than the inner diameter of the first through hole 111 and/or the second through hole 121.
The arrangement of the guide inclined plane 421 can also correct the movement direction error of the first squeeze rivet head 410/the second squeeze rivet head 420, so that the first squeeze rivet head and the second squeeze rivet head move towards the axial direction of the sleeve 600, the stress of each deformation part 131 is consistent, and the squeeze rivet effect is improved.
