The spacing material blocking mechanism 503 comprises a first material blocking plate 507, a second material blocking plate 508, a U-shaped support 501 and a material blocking plate driving power mechanism 506, one end of the first material blocking plate 507 is fixed at one end of the U-shaped support 501, one end of the second material blocking plate 508 is fixed at the other end of the U-shaped support 501, the lower material channel 505 is installed in a U-shaped groove of the U-shaped support 501, the first material blocking plate 507 and the second material blocking plate 508 are arranged at two sides of the lower material channel 505 in an up-down parallel mode along the Z-axis direction, the distance between the upper portion and the lower portion of the first material blocking plate 507 and the second material blocking plate 508 only accommodates a half hollow rivet, the material blocking plate driving power mechanism 506 is a third driving cylinder, an output shaft of the third driving cylinder is connected with the U-shaped support 501, and the third driving cylinder drives the U-shaped support 501 to reciprocate along the Y-axis direction, thereby driving the first striker plate 507 and the second striker plate 508 to reciprocate simultaneously along the Y-axis direction.

When the U-shaped bracket 501 moves along one side of the Y axis, the half-hollow rivet that previously falls between the first striker plate 507 and the second striker plate 508 falls to the rivet clamping opening 60110 of the rivet sending mechanism 601, then the third driving cylinder drives the U-shaped bracket 501 to reset along the opposite direction of the Y axis, and the next rivet falls between the first striker plate 507 and the second striker plate 508.

Pressing down the positioning mechanism 4: including pushing down drive power mechanism 401 and pressure head 402, push down drive power mechanism 401 is fourth drive cylinder, fourth drive cylinder's output shaft with pressure head 402 is connected, fourth drive cylinder with still be equipped with pressure sensor between the pressure head 402.

In the riveting process, the pressure head 402 moves downwards to be in contact with and pressed against the steel cap 12 of the brake disc to be riveted, so that the friction ring 11 and the steel cap 12 of the composite disc can be prevented from being dislocated in the riveting process, and the pressure sensor ensures that the stress of the rivet is consistent in the riveting process.

The working process of the automatic riveting equipment for the composite brake disc is as follows:

firstly, mounting a friction ring 11 and a steel cap 12 of a composite brake disc to be riveted on a positioning tool 7 of the rotary positioning mechanism 3, wherein the elastic support ring 8 is positioned in an inner ring of the friction ring 11;

secondly, starting the equipment, driving the rotary positioning mechanism 3 to drive the workpiece to rotate by the rotary driving motor 303, stopping rotating after the detector 10 automatically positions the riveting hole position of the workpiece, and pressing the workpiece by the pressing head 402;

thirdly, the guide driving power mechanism 6028 acts to push the slope guide block 6027 to move upwards along the Z-axis, the slope guide part of the slope guide block 6027 pushes the anvil bowl 6022 to move forwards, and the punch pin 6023 aligns with the rivet hole of the workpiece;

fourthly, when the striker plate driving power mechanism 506 is used for driving the first striker plate 507 and the second striker plate 508 to move along one side of the Y axis, the semi-hollow rivet which is previously dropped between the first striker plate 507 and the second striker plate 508 is dropped to the rivet clamping opening 60110 of the rivet sending mechanism 601;

fifthly, the output shaft of the nail pushing rod driving power mechanism 6019 is pushed forward, and the semi-hollow rivet is turned and upset along the arc-shaped curved surface groove 6026 of the anvil bowl 6022;

sixthly, the punch pin 6023 of the flanging mechanism 602 is retracted, the rotary positioning mechanism 3 drives the workpiece to rotate to the next rivet hole until all the rivet holes on the workpiece are riveted, all the mechanisms return to the original position, and the process is finished.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
