Subsequently, the rotating motor 611 is started, and the rotating motor 611 drives the pushing plate 62 to slide towards the rotating disc 11 through the screw rod 612 and the connecting block 613, so that the shaft sleeve 4 is slid onto the rotating disc 11 along with the pushing groove 621. At this time, the mandrel 5 is lowered by the lifting cylinder 13, and the pressing wheel 72 passes through the yielding through groove 622 to tightly press the shaft sleeve 4 against the turntable 11. The turntable 11 is then rotated, the turntable 11 bringing the shaft element and the centering sleeve 81 together. Under the effect of first protective sheath 811, produce the friction between first protective sheath 811 and the dabber 5, and make the inside wall of axle sleeve 4 difficult and the dabber 5 between the lateral wall take place the friction, process the lateral surface of axle sleeve 4 through the axial vibration of oilstone 14 again to make the difficult mar that produces of inside wall of axle sleeve 4, improved the processingquality of axle sleeve 4. When the centering protection sleeve 81 is installed, the second shaft element 52 is detached from the first shaft element 51, and then the centering protection sleeve 81 is sleeved downwards from the top of the second shaft element 52, so that the centering protection sleeve 81 can be conveniently installed.
After the outer side surface of the shaft sleeve 4 is processed, the mandrel 5 is lifted, and the pushing plate 62 is slid in the direction away from the turntable 11, so that the pushing plate 62 is reset. Under the action of the limiting groove 8111, the shaft sleeve 4 slides along with the pushing plate 62, so that the processed shaft sleeve 4 slides from the turntable 11 to the feeding table 22. In the process that the next shaft sleeve 4 is pushed to the feeding position on the feeding table 22 by the pushing rod 23, the positioning plate 16 pushes the processed shaft sleeve 4 to the discharging conveyer belt 31, and the processed shaft sleeve is conveyed to the next procedure. The feeding and the discharging of the shaft sleeve 4 are all automatically carried out, the shaft sleeve 4 is convenient to feed, and the working efficiency is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
