In these fields, copper bushings are often used as wear-resistant parts, such as cup-shaped bushings, straight bushings, tapered bushings, copper shaft sleeves, copper bushings, and copper bearing shells, for critical components such as machine frames, spindles, and drive shafts.

[0003] Chinese Patent No. CN218082030U discloses a copper sleeve grinding device, belonging to the field of mechanical technology. The copper sleeve grinding device includes a workpiece placement mechanism and a grinding mechanism for grinding the workpiece. The grinding mechanism includes a frame and two grinding frames. The frame includes an upper frame and a lower frame. Two first sliders are slidably connected to the upper frame, and first push rod motors are fixedly connected to the two first sliders. The two first sliders are respectively connected to the upper ends of the two grinding frames. Two second sliders are slidably connected to the lower frame, and second push rod motors are fixedly connected to the two second sliders. The two second sliders are respectively connected to the lower ends of the two grinding frames. An upper grinding disc and a lower grinding disc are slidably connected to each grinding frame. This invention has the advantage of being able to grind both the upper and lower surfaces of a copper sleeve base simultaneously.

[0004] However, the above patent has the following shortcomings: the above patent uses two grinding discs distributed vertically to grind the workpiece, but it cannot grind the inside of the workpiece, so it needs to be improved. Summary of the Invention
