Referring to fig. 2 and 4, the mandrel 5 is provided with a tightening component 7 and a protection component 8, the tightening component 7 is used for tightening the shaft sleeve 4 on the rotary table 11 to enable the shaft sleeve 4 and the rotary table 11 to synchronously rotate, and the protection component 8 is used for protecting the inner side wall of the shaft sleeve 4 from being abraded easily. The mandrel 5 comprises a first shaft member 51 and a second shaft member 52, the first shaft member 51 is far away from the rotating disc 11 compared with the second shaft member 52 and is connected with a piston rod of the lifting cylinder 13, and the second shaft member 52 is detachably arranged at the bottom of the first shaft member 51 through a countersunk head screw. The abutting assembly 7 comprises a mounting shaft 71 and a pressing wheel 72, wherein the mounting shaft 71 penetrates through the mandrel 5 along the radial direction of the mandrel 5 and is fixedly mounted on the mandrel 5 through screws. Spool 711 is fixedly connected to both ends of the mounting shaft 71, and the spool 711 is arranged coaxially with the mounting shaft 71. The spool 711 comprises a shaft portion 7111 and limiting discs 7112 fixedly connected to two ends of the shaft portion 7111, the limiting discs 7112 close to the mounting shaft 71 are fixedly connected with the mounting shaft 71, and the limiting discs 7112 far away from the mounting shaft 71 are detachably connected with the shaft portion 7111 through screws. The pressing wheel 72 is sleeved on the shaft portion 7111, so that the pressing wheel 72 is rotatably mounted at both ends of the mounting shaft 71.

Referring to fig. 4, the protective assembly 8 includes a centering boot 81 and a friction plate 82, the friction plate 82 being a nylon friction plate 82 in this embodiment. The centering protection sleeve 81 is sleeved on the second shaft element 52, the centering protection sleeve 81 comprises a first protection sleeve 811 and a second protection sleeve 812 which are coaxially arranged, and the first protection sleeve 811 is located between the inner side wall of the shaft sleeve 4 and the outer side wall of the mandrel 5. The second shaft 52 is fixedly connected to a limiting ring 521 on a peripheral side wall of a bottom of the second shaft 521, and the limiting ring 521 is sleeved on the second shaft 52 and is fixedly connected to the second shaft 52. One surface of the first protection sleeve 811 close to the turntable 11 is provided with a limiting groove 8111 for the limiting ring 521 to be embedded, and the depth of the limiting groove 8111 is smaller than the axial length of the first protection sleeve 811, so that the centering protection sleeve 81 is limited on the mandrel 5.

Referring to fig. 2 and 4, the second protection sleeve 812 is fixedly connected to the top of the first protection sleeve 811, the outer diameter of the second protection sleeve 812 is larger than that of the first protection sleeve 811, and the second protection sleeve 812 is far away from the turntable 11 than the shaft sleeve 4, i.e. the second protection sleeve 812 is located above the shaft sleeve 4. The friction plate 82 is annular, and the friction plate 82 is located between the second protective sleeve 812 and the shaft sleeve 4 and fixedly connected with the bottom surface of the second protective sleeve 812, so that the centering protective sleeve 81 and the friction plate 82 can be lifted and lowered synchronously with the mandrel 5. The top surface of the second protective cover 812 is always abutted against the peripheral sidewall of the bottom of the pressing wheel 72, and the friction plate 82 can descend along with the mandrel 5 to be abutted against the top surface of the shaft sleeve 4 and tightly abut the shaft sleeve 4 against the turntable 11.

The implementation principle of a superfinishing machine for processing the side surface of the shaft is as follows: when the shaft sleeve 4 is conveyed to the turntable 11 for processing, the second sliding cylinder 1511 is started first, so that the pushing rod 23 slides to the middle of the feeding conveyer belt 21 in the width direction along the width direction of the feeding conveyer belt 21. The left end of the positioning plate 16 is located at the end of the feeding conveyor belt 21 in the advancing direction and abuts against the shaft sleeve 4. Then, the first sliding cylinder 19 is started, the first sliding cylinder 19 drives the pushing rod 23 and the positioning plate 16 to slide, so that the shaft sleeve 4 is pushed to the feeding position on the feeding table 22, and the shaft sleeve 4 is located in the positioning groove at the moment.

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.
