[0012] Furthermore, a handwheel is fixedly mounted on the rotating screw.

[0013] The advantages of this utility model are:

[0014] This invention places the carbon graphite bushing to be processed between a drive disc and a top cone. By rotating the drive disc and the drive disc relative to each other, the rectangular slider moves along the first slide groove under the action of the two pairs of sliding columns in the middle of the slide groove. This, in turn, drives the clamping plate to move. The clamping plate contacts one end of the carbon graphite bushing, fixing the end of the bushing. A locking nut three locks the relative rotational position of the drive disc and the drive disc. The other end of the carbon graphite bushing rests against the top cone. Simultaneously, the drive threaded sleeve rotates relative to each other. Through the threaded connection between the drive threaded sleeve and the threaded sleeve, the sliding bracket slides along the rectangular slide groove. This causes the top cone to act in the opposite direction, compressing the inner spring. Under the action of the reaction force, the other end of the carbon graphite bushing is stably fixed, thus fixing both ends of the carbon graphite bushing. Manually rotating the handwheel drives the rotating screw, which in turn drives the slide to bring the carbon graphite bushing closer to the grinding cone. Simultaneously, the first actuator motor is activated, driving the grinding cone to rotate. Through contact between the grinding cone and the carbon graphite bushing, the rounded corners of the carbon graphite bushing are chamfered. Simultaneously, the first sliding column slides along the groove in the ear plate, driving the first sliding plate to slide along the rectangular groove. The sliding plate then moves the rotating platform and the grinding cone, changing the processing position between the grinding cone and the carbon graphite bushing. Simultaneously, the rotating platform and the first sliding plate rotate relative to each other, changing the contact angle between the conical annular surface of the grinding cone and the carbon graphite bushing, thus adjusting the chamfer angle of the carbon graphite bushing. Furthermore, when rounding or chamfering is required at both ends of the carbon graphite bushing, the rotating support plate rotates relative to each other, simultaneously driving the threaded sleeve to disengage the top cone from the carbon graphite bushing. As the rotating support plate rotates, the other end of the carbon graphite bushing contacts the grinding cone, achieving rounding or chamfering at the end of the carbon graphite bushing.
