after the fallen stepped shaft sleeve falls into the material blocking block, the feeding cylinder stretches out to eject the stepped shaft sleeve, at the moment, the driving cylinder stretches out to enable the feeding clamp to clamp the stepped shaft sleeve by hand, after clamping, the driving cylinder contracts and lifts, and then the driving cylinder moves to the right side along the guide rail seat under the control of the electromagnetic valve and moves to the position above the grinding wheel and the adjusting wheel;
fifthly, clamping the ground stepped shaft sleeve by a blanking clamping hand under the drive of a driving cylinder, and driving the grinding wheel to retreat by a pushing device after clamping, so that the stepped shaft sleeve is clamped out and lifted upwards by the blanking clamping hand;
the electromagnetic valve controls the driving cylinder after clamping out, and then the unprocessed step shaft sleeve on the feeding clamping hand is placed between the grinding wheel and the adjusting wheel, the pushing device drives the grinding wheel to advance, so that the step part of the step shaft sleeve is clamped in the groove to position and grind the shaft sleeve part of the step shaft sleeve;
when the grinding wheel is grinding the stepped shaft sleeve, the driving cylinder moves leftwards on the guide rail seat, and is driven to extend out after moving to the upper parts of the feeding rail and the discharging bin, the feeding clamping hand is loosened to put the processed stepped shaft sleeve in the discharging bin, and meanwhile, the feeding clamping hand is opened to clamp the unprocessed stepped shaft sleeve ejected by the feeding cylinder;
and (3) cycling to the fourth step.
7. The centerless grinding process for machining a stepped bushing using a loading and unloading conveyor for a centerless grinding machine according to claim 6, wherein: the grinding area between the grinding wheel and the adjusting wheel needs to be cooled by adding cooling liquid.
