The lifting plate 2 is connected to a hydraulic press, and the lifting plate 2 can perform lifting and lowering movements under the drive of the hydraulic press. Connecting ears 5 are provided on both sides of the pressure platform 1, and guide holes 6 are provided on the connecting ears 5. The lifting plate 2 is provided with guide rods 7 corresponding to the guide holes 6. The coordinated use of the guide rods 7 and the guide holes 6 can improve the verticality of the lifting plate 2 during the lifting and lowering movement, thereby ensuring the verticality when the rivet is pressed in, and avoiding damage to the brake disc caused by the tilt of the rivet. The stepper motor 3 is fixed to the middle of the top surface of the lifting plate 2, and the rotating plate 4 is located below the lifting plate 2 and is connected to the stepper motor 3 in the middle. The rotating plate 4 can realize precise angle rotation under the drive of the stepper motor 3. The top surface of the rotating plate 4 is fixedly connected with a hemispherical slider 8 that is slidably connected to the lifting and lowering plate 2. The hemispherical slider 8 can not only transmit the pressure of the lifting and lowering plate 2 to the rotating plate 4, but also reduce the friction resistance between the rotating plate 4 and the lifting and lowering plate 2 when the rotating plate 4 rotates. Punching cylinders 9 are provided at both ends of the bottom surface of the rotating plate 4. The two punching cylinders 9 can ensure that the wheel hub and the brake disc will not tilt or move when the rivet is punched, so as to avoid damage to the brake disc caused by the tilt of the rivet. A protective layer 10 is provided on the bottom surface of the punching cylinder 9. The protective layer 10 is a rubber pad. The protective layer 10 can prevent collision damage between the punching cylinder 9 and the rivet.

[0024] When in use, select a suitable pad 11 according to the shape of the wheel hub and brake disc and install it on the pressure platform 1, place the wheel hub and brake disc on the pad 11, use the brake disc limit block 15 to fix the brake disc, and use the wheel hub limit block 16 to fix the wheel hub, then start the stepper motor 3 to make the two punching cylinders 9 correspond to the two rivet holes respectively, start the hydraulic press to make the lifting and lowering plate 2 drive the punching cylinder 9 to descend to complete the pressing of the two rivets, then the hydraulic press drives the punching cylinder 9 to rise and return to its position, the stepper motor 3 controls the rotating plate 4 to rotate to a suitable angle according to the distribution position of the rivet holes, and the hydraulic press is started again to perform the rivet pressing operation, and the operation of the stepper motor 3 and the hydraulic press is cycled until all rivet holes are fully pressed with rivets.

[0025] Therefore, the utility model adopts the brake disc rivet pressing device of the above structure, which can perform rivet pressing operations on brake discs with different rivet quantity requirements.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
