[0043] The processing head assembly 7 includes a processing barrel 71; illustratively, as Figure 4 and Figure 5 shown.

[0044] One end of the processing cylinder 71 is an open structure, and a processing groove 72 is opened on one side wall of the processing cylinder 71, a first assembly cavity 73 is provided at the bottom of the processing groove 72 and the inner wall of the processing cylinder 71, a compression spring 74 is provided at the bottom end of the inner wall of the first assembly cavity 73, a limiting ring 76 is fixedly connected to the top of the inner wall of the first assembly cavity 73, a strong magnetic block 75 is movably connected to the inner wall of the first assembly cavity 73, one end of the strong magnetic block 75 is movably connected to the compression spring 74, and the other end of the strong magnetic block 75 is movably connected to the limiting ring 76, a second assembly cavity 77 is provided at the top of the processing groove 72 and the inner wall of the processing cylinder 71, a plurality of groups of buffer mechanisms 78 are movably clamped on the outer wall of the processing cylinder 71, and the plurality of groups of buffer mechanisms 78 are arranged in a ring array with the central axis of the processing cylinder 71 as the center.

[0045] The buffer mechanism 78 includes two sets of guide posts 781; illustratively, Figure 6 shown.

[0046] The two groups of guide columns 781 both penetrate the processing cylinder 71, and one end of the two groups of processing cylinders 71 is fixedly connected with an elastic arc piece 782, and the elastic arc piece 782 is arranged on the inner wall of the second assembly cavity 77, and the other end of the two groups of processing cylinders 71 is fixedly connected with an adjustment plate 783, and the adjustment plate 783 is threaded with a bolt 784, and one end of the bolt 784 is rotatably connected to the outer wall of the processing cylinder 71.

[0047] Specifically, the second assembly cavity 77 is communicated with the bottom of the lower barrel 57. When the rivet nut 53 in the lower barrel 57 falls downward, the rivet nut 53 can be adsorbed under the action of the strong magnetic block 75, so that the fallen rivet nut 53 can quickly enter the second assembly cavity 77 and contact with the plurality of groups of elastic arc-shaped pieces 782 in the second assembly cavity 77. The plurality of groups of elastic arc-shaped pieces 782 can be used to compatibly position the fallen rivet nuts 53 of different diameters. In the process of rotating the bolt 784, the adjustment plate 783 threadedly connected to the bolt 784 synchronously drives the elastic arc-shaped piece 782, so that the elastic arc-shaped piece 782 moves to different positions in the second assembly cavity 77 to meet the needs of rivet nuts 53 of different sizes.

[0048] The processing groove 72 is used to place the workpiece to be riveted, and the strong magnetic block 75 can also be used to adsorb and position the hole position of the placed workpiece to be riveted to prevent the displacement of the workpiece to be riveted during the riveting process.

[0049] The output end of the cylinder 2 can first push the first reset rod 36, so that the bottom end of the first reset rod 36 passes through the lower barrel 57, the second assembly cavity 77 and the first assembly cavity 73 in sequence. When the bottom end of the first reset rod 36 enters the second assembly cavity 77, the rivet nut 53 in the second assembly cavity 77 is squeezed and assembled with the hole position of the workpiece to be riveted in the processing groove 72, and the bottom end of the rivet nut 53 passes through the hole position of the workpiece to be riveted, and extends to the upper surface of the strong magnetic block 75 to elastically resist the compression spring 74, so that the strong magnetic block 75 continues to adsorb and position the hole position of the workpiece to be riveted;

[0050] After the output end of the cylinder 2 is reset to cancel the conflict with the first reset rod 36, the first reset rod 36 is restored to its original position under the action of the spring on the first reset rod 36, and the second reset rod 37 is moved to the output end of the cylinder 2 under the action of the output end of the second electric push rod 39, and the working principle of the output end of the cylinder 2 and the pushing of the first reset rod 36 is repeated again, so that the second reset rod 37 passes through the discharge barrel 57, the second assembly cavity 77 and the first assembly cavity 73 again, and the electric rivet gun set at the bottom end of the second reset rod 37 is used to rivet the rivet nut 53 in the hole position of the workpiece to be riveted.

[0051] The universal riveting device proposed in the embodiment of the present invention has the following working principle:

[0052] The second assembly cavity 77 is connected with the bottom of the lower barrel 57. When the rivet nut 53 in the lower barrel 57 falls downward, the rivet nut 53 can be adsorbed under the action of the strong magnetic block 75, so that the fallen rivet nut 53 can quickly enter the second assembly cavity 77 and contact with the plurality of groups of elastic arc-shaped pieces 782 in the second assembly cavity 77. The plurality of groups of elastic arc-shaped pieces 782 can be used to compatibly position the fallen rivet nuts 53 of different diameters. In the process of rotating the bolt 784, the adjustment plate 783 threadedly connected to the bolt 784 synchronously drives the elastic arc-shaped piece 782, so that the elastic arc-shaped piece 782 moves to different positions in the second assembly cavity 77 to meet the requirements of rivet nuts 53 of different sizes.

[0053] The processing groove 72 is used to place the workpiece to be riveted, and the strong magnetic block 75 can also be used to adsorb and position the hole position of the workpiece to be riveted to prevent the displacement of the workpiece to be riveted during the riveting process. In addition, when the first electric push rod 8 drives the flat plate 51 to fall, the processing cylinder 71 can be driven to fall synchronously, and the processing groove 72 can be adjusted to different heights, so that the riveting device can meet the hole positions of workpieces to be riveted at different heights, and can be compatible with different types of workpieces to be riveted.

[0054] The output end of the cylinder 2 can first push the first reset rod 36, so that the bottom end of the first reset rod 36 passes through the lower barrel 57, the second assembly cavity 77 and the first assembly cavity 73 in sequence. When the bottom end of the first reset rod 36 enters the second assembly cavity 77, the rivet nut 53 in the second assembly cavity 77 is squeezed and assembled with the hole position of the workpiece to be riveted in the processing groove 72, and the bottom end of the rivet nut 53 passes through the hole position of the workpiece to be riveted, and extends to the upper surface of the strong magnetic block 75 to elastically resist the compression spring 74, so that the strong magnetic block 75 continues to adsorb and position the hole position of the workpiece to be riveted;

[0055] After the output end of the cylinder 2 is reset to cancel the conflict with the first reset rod 36, the first reset rod 36 is restored to its original position under the action of the spring on the first reset rod 36, and the second reset rod 37 is moved to the output end of the cylinder 2 under the action of the output end of the second electric push rod 39, and the working principle of the output end of the cylinder 2 and the pushing of the first reset rod 36 is repeated again, so that the second reset rod 37 passes through the discharge barrel 57, the second assembly cavity 77 and the first assembly cavity 73 again, and the electric rivet gun arranged at the bottom end of the second reset rod 37 is used to rivet the rivet nut 53 in the hole of the workpiece to be riveted.
