[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figures 1 to 4 This utility model discloses a ceramic friction disc arc surface polishing device, which includes a worktable 1, a support frame 2 fixedly connected to the upper end of the worktable 1, a fixing device 3 provided at the upper end of the support frame 2, a fixing rod 19 fixedly connected to the worktable 1, a placement platform 4 fixedly connected to the upper end of the fixing rod 19, a rotating rod 5 rotatably connected to the outer surface of the fixing rod 19, a rotating plate 6 fixedly connected to the outer surface of the rotating rod 5, a first sliding groove 7 provided on the rotating plate 6, a movable frame 8 slidably connected to the first sliding groove 7, a second sliding groove 9 provided on the movable frame 8, a guide rod 10 fixedly connected inside the second sliding groove 9, a slider 11 slidably connected to the guide rod 10, and a polishing machine 12 fixedly connected to the slider 11.

[0019] The first electric push rod 13 is fixedly connected inside the first slide groove 7. The output end of the first electric push rod 13 is fixedly connected to the moving frame 8. A spring 14 is sleeved on the outer surface of the guide rod 10. One end of the spring 14 is fixedly connected to the slider 11, and the end of the spring 14 away from the slider 11 is fixedly connected to the moving frame 8. When the polishing machine 12 contacts the arc surface of the friction disk, the spring 14 is compressed and generates elastic force, so that the polishing machine 12 can adapt to the undulation of the arc surface. This can ensure the uniformity of polishing pressure and avoid over-polishing or uneven polishing caused by rigid contact, thereby further improving the polishing accuracy and surface quality.

[0020] A motor 15 is fixedly connected to the workbench 1. A first gear 16 is fixedly connected to the output end of the motor 15. A second gear 17 is fixedly connected to the outer surface of the rotating rod 5. The first gear 16 and the second gear 17 mesh, and the rotational motion of the motor 15 is transmitted to the rotating rod 5 through gear transmission. This ensures that the rotating rod 5 drives the rotating plate 6 and the friction disk to rotate at a constant speed, so that the polishing machine 12 forms a uniform polishing trajectory on the arc surface of the friction disk, ensuring the consistency of the polishing effect.

[0021] The fixing device 3 includes a second electric push rod 301 and a fixing plate 302. The second electric push rod 301 is fixedly connected to the support frame 2. The output end of the second electric push rod 301 is fixedly connected to the fixing plate 302. The fixing plate 302 is fixedly connected with a rubber pad 18, which can increase the friction with the surface of the friction disk, prevent slippage during clamping, and avoid the fixing plate 302 directly contacting the friction disk to avoid surface scratches. This achieves flexible fixing of friction disks of different specifications and improves the applicability of the device.

[0022] Working Principle: In use, the friction disc is placed on the placement table 4. Then, the second electric push rod 301 pushes the fixing plate 302 downwards until the rubber pad 18 is in close contact with the upper surface of the ceramic friction disc on the placement table 4. The elastic deformation of the rubber pad 18 generates a clamping force, firmly fixing the friction disc on the placement table 4 while preventing damage to the surface of the friction disc. Next, according to the outer diameter of the friction disc to be polished, the extension and retraction of the first electric push rod 13 outputs power to drive the moving frame 8 to move radially in the first slide groove 7, adjusting the polishing machine 12 to a suitable initial polishing position, ensuring that the polishing head is aligned with the polishing area of ​​the friction disc's arc surface. Then, the motor 15 outputs power to drive the first gear 16 to rotate, meshing with the second gear 17, which in turn drives the rotating rod 5 to rotate, driving the rotating plate 6. This, in turn, causes the moving frame 8 and the polishing machine 12 to perform circular motion around the axis of the rotating rod 5, allowing the polishing machine 12 to polish the friction disc. Meanwhile, as the polishing machine 12 moves, the slider 11 slides along the guide rod 10, and the spring 14 automatically adjusts its compression according to the curvature change of the arc surface, ensuring that the polishing head always fits against the arc surface of the friction disk, performing polishing operations with appropriate pressure. Through the rotational movement of the rotating plate 6, the polishing machine 12 achieves comprehensive polishing of the arc surface on the friction disk.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
