The feeding base slide plate 22 is fixedly installed on the feeding base frame 21, and the feeding base slide plate 22 has a downward tilt angle between the feeding direction and the horizontal plane. Preferably, the tilt angle is 1°-5°, and most preferably 2°. When the bearing workpiece moves onto the feeding device 2, it automatically slides downward. The two feeding limit baffles 23 are respectively installed on both sides of the feeding base slide plate 22, and the two feeding nylon baffles 24 are respectively installed inside the two feeding limit baffles 23 to limit the feeding trajectory of the bearing workpiece. The end of the base slide plate along the feeding direction has two through holes for the two limit pins to pass through. The two limit pins are respectively connected to the two limit cylinders 25. The inner limiting cylinder 25 limits the movement. When the inner limiting cylinder 25 is raised, the bearing workpiece will automatically move to the outer limiting cylinder 25 for limiting. At this time, the inner limiting cylinder 25 begins to block and limit the movement downward, thus realizing automatic feeding.

[0031] like Figure 5 and Figure 6 As shown, the rotating device 3 includes a turntable base 31, a pneumatic turntable 32, a turntable connecting shaft 33, two rotating roller base frames 34, rotating rollers 35, and a locking mechanism 36. The bottom of the turntable base 31 is fixedly mounted on the equipment base 1, and the pneumatic turntable 32 is fixedly mounted on the turntable base 31. The pneumatic turntable 32 is connected to the rotating rollers 35 through the turntable connecting shaft 33.

The pneumatic-hydraulic booster cylinder 41 controls the movement of the rolling letterhead assembly 48, causing the rolling letterhead assembly 48 to contact the surface of the bearing workpiece. When the rolling letterhead assembly 48 moves to the rolling position, the rolling cylinder 40 moves, pushing the rolling letterhead assembly 48, causing the rolling letterhead assembly 48 to move linearly along the outer ring of the bearing workpiece, completing the rolling printing. Preferably, a limit rod is installed between the guide post 43 and the pneumatic-hydraulic booster cylinder 41, and a limit rod nut is installed on the limit rod. The depth of the printed characters can be adjusted by adjusting the adjusting nut. After adjustment, tighten the nut. After adjusting to the desired depth, apply pressure and roll the characters.

To maintain the consistency between the fixed letter mold and the rotating round letter mold, a rotating round letter mold anti-reverse positioning device can be provided. Once a rolling process is completed, the character-changing cylinder operates, pushing the round character head to change the serial number, changing only one digit of the serial number each time.

[0034] like Figure 10 and Figure 11As shown, the unloading device 5 includes: an unloading base frame 51, an unloading base slide plate 52, two unloading limiting baffles 53, and two unloading nylon baffles 54. The unloading base slide plate 52 is fixedly installed on the unloading base frame 51, and the unloading base slide plate 52 has a downward tilt angle between itself and the horizontal plane along the unloading direction. The two unloading limiting baffles 53 are respectively installed on both sides of the unloading base slide plate 52, and the two unloading nylon baffles 54 are respectively installed inside the two unloading limiting baffles 53. By rotating the rotating mechanism, the workpiece is rotated into the unloading mechanism. The unloading mechanism has a tilt angle, preferably 1°-5°, and most preferably 2°. The tilt angle difference allows the workpiece to move freely downward to the next station.

[0035] Working principle:

[0036] After the bearing workpiece is moved to the rotating device position by the feeding device, the pneumatic turntable operates, and the rotating device rotates. Once the bearing workpiece reaches the rolling lettering position, the locking cylinder in the rotating device locks the rotating mechanism with a pin. The pneumatic-hydraulic booster cylinder then pushes the rolling lettering assembly downwards. After the rolling lettering assembly reaches the rolling lettering position, the pneumatic-hydraulic booster cylinder pressurizes the assembly. After pressurization, the rolling lettering cylinder operates, pushing the rolling lettering assembly along the outer ring of the bearing workpiece. After the lettering is pushed, the pneumatic-hydraulic booster cylinder retracts and simultaneously depressurizes. After depressurization, the rolling lettering cylinder retracts, and the letter-changing cylinder operates to change the serial number. The locking pin in the rotating device opens, the pneumatic turntable operates, the unloading is completed, and the rolling lettering is finished.
