[0002] Automobile brakes are the braking devices of automobiles. Brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of drum brakes is the brake drum, whose working surface is a cylindrical surface; the rotating element of disc brakes is the rotating brake disc, whose end surface is the working surface.

[0003] The brake disc is made of alloy steel and fixed on the wheel, rotating with the wheel. This type of brake has fast heat dissipation, light weight, simple structure and easy adjustment.

[0037] Working principle:

[0038] Place the brake disc that needs to be punched on the upper surface of the overlapping placement plate 3, and then start the first driving cylinder 4, the piston end of the first driving cylinder 4 brings the first connecting disc 5 up, the first connecting disc 5 brings the first servo motor 6 up, the first servo motor 6 brings the fixed pressure plate 7 up, and then start the first servo motor 6 again, the first servo motor 6 brings the fixed pressure plate 7 to rotate, so that the fixed pressure plate 7 rotates to the top of the brake disc, and then start the first driving cylinder 4 again, the piston end of the first driving cylinder 4 brings the first connecting disc 5 down, so that the fixed pressure plate 7 is lowered and pressed against the surface of the brake disc, so as to fix the brake disc;

[0039] The third servo motor 13 is started, and the output shaft of the third servo motor 13 rotates with the threaded rotating rod 14. Since the lifting mounting plate 15 is threadedly connected to the outer surface of the threaded rotating rod 14, when the threaded rotating rod 14 rotates, the lifting mounting plate 15 descends with the lifting slide bar 16, and the lifting slide bar 16 descends with the fixed connecting seat 17, and the rotating connecting shaft 18 descends with the drilling drill 19 until the second connecting cover 23 descends to fit with the upper surface of the brake disc;

[0042] The fourth servo motor 20 is started, and the output shaft of the fourth servo motor 20 rotates with the first sprocket, and the three rotating connecting shafts 18 are rotated synchronously through the chain, and the rotating connecting shaft 18 rotates with the drilling drill 19, and the third servo motor 13 is started again, and the output shaft of the third servo motor 13 rotates with the threaded rotating rod 14.

When the drilling drill 19 descends, since the accordion cover 22 can be retracted, the second connecting cover 23 is always attached to the upper surface of the brake disc. When the fixed connecting seat 17 descends, the material receiving shell 29 will also descend synchronously. Therefore, when the drilling drill 19 descends, the second driving cylinder 25 is started synchronously, and the piston end of the second driving cylinder 25 rises synchronously with the material receiving shell 29 and keeps in contact with the lower surface of the brake disc.
