During operation, the first push rod motor 9 is started, so that the output shaft of the first push rod motor 9 extends, and the lifting platform 8 is driven to ascend. The lifting platform 8 exposes polishing sand when rising to the top, and sleeves to be polished are sleeved on the limiting columns 11 and are in a fixed state. A push rod motor 9 drives the lifting platform 8 to move downwards, and the polishing sand gradually submerges the sleeve in the downward movement process of the lifting platform 8. Push rod motor 9 stop work when push rod motor 9 drives elevating platform 8 and removes to the bottommost, and driving motor 4 begins work simultaneously, and driving motor 4 drives a band pulley 6 and rotates for a hold-in range 7 rotates, thereby makes sleeve 5 produce and rotates. When the sleeve 5 rotates, the lifting platform 8 and the sleeve are driven to rotate, the surface of the sleeve 5 rotating at a high speed is contacted with polishing sand, and burr particles on the surface of the sleeve are knocked off, so that the grinding work of the sleeve is completed. The sand pressing mechanism can enable the polishing sand to be tightly attached to the complex contour surface of the sleeve, so that the grinding efficiency of the sleeve is ensured.

Through being provided with transmission shaft 12, driving motor 4 during operation drives No. three band pulleys 14 and rotates to drive No. two hold-in range 15 and rotate. The second synchronous belt 15 drives the third belt wheel 14 to rotate, so that the transmission shaft 12 rotates synchronously, and the cam 16 on the transmission shaft 12 rotates. The cam 16 intermittently presses the pressing plate 18 during rotation, so that the pressing plate 18 drives the connecting rod 17 and the pushing plate 19 to move towards the sleeve. The moving push plate 19 pushes the polishing sand to the direction of the casing, so that the polishing sand enters between the adjacent cambered surfaces of the casing, and the polishing sand can fill the gap between the adjacent cambered surfaces of the casing. When the cam 16 moves away from the pressing plate 18, the spring 20 drives the pressing plate 18 and the pushing plate 19 to return to the initial position, so that the pushing work is continued.

When the rectangular plate 23 enters the middle of the adjacent arc-shaped part of the sleeve under the driving of the push plate 19 and reaches the farthest stroke, the electromagnetic valve opens the air pipe, so that the compressed air in the air cylinder 24 enters the first telescopic rod 25 and the second telescopic rod 27, and the first telescopic rod 25 and the second telescopic rod 27 drive the first plate 26 and the second plate 28 to move respectively. The polishing sand on the moving path is pressed during the movement of the first plate 26 and the second plate 28, so that the polishing sand can be in close contact with the cylindrical part of the casing, and the grinding effect of the polishing sand on the casing is further improved.
As a further scheme of the invention, more than two third telescopic rods 29 are fixed at the top end of the rectangular plate 23 at equal intervals along the length direction of the connecting rod 17, a third plate 30 is fixed at one end of each third telescopic rod 29 far away from the rectangular plate 23, a probe 31 is fixed at the top end of each third plate 30, an air pipe is arranged between each third telescopic rod 29 and the air cylinder 24, and an electromagnetic valve is arranged in each air pipe; during working, the bottom of the cambered surface part of the sleeve often has a depression, and the contact strength of the polishing sand and the depression part of the sleeve is not enough, so that the grinding efficiency is influenced. By providing the third expansion link 29, the third expansion link 29 is extended after the gas in the gas cylinder 24 enters the third expansion link 29, so that the third plate 30 moves upward. The polishing sand is driven to contact with the inner concave surface of the sleeve in the upward movement process of the third plate 30, and the probe 31 at the top of the third plate 30 contacts with the concave part of the sleeve in the upward movement process of the third plate 30, so that the movement amplitude of each third plate 30 is different. The three plates 30 with different heights ensure good contact between the polishing sand and the concave surface of the sleeve, so that normal polishing of the concave surface of the sleeve is ensured.

The pressure sensor transmits the measured data to the controller, and the controller controls the second push rod motor 32 through different numerical values. When the pressure value is increased sharply, a plurality of rectangular plates 23 enter between the same adjacent cambered surface parts, so that the second spring is pressed greatly. At this time, it is explained that the distance between the sliders 22 is too small, and the controller drives the sliders 22 connected to the controller to move upwards by controlling the second push rod motor 32, so that the distance between each two adjacent sliders 22 is increased. The distance between the rectangular plates 23 is increased by increasing the distance between the sliding blocks 22, so that the adjacent rectangular plates 23 cannot enter the same gap at the same time, and the normal work of the rectangular plates 23 is ensured. Conversely, the smaller the pressure value indicates that there is no rectangular plate 23 in the gap, and the second push rod motor 32 moves downward, so that the distance between the adjacent sliders 22 becomes smaller.
As a further aspect of the present invention, a rubber sleeve 33 is fixed between the first plate 26, the second plate 28 and the third plate 30 on the same rectangular plate 23, and the rubber sleeve 33 is used for preventing polishing sand from entering; during operation, through being provided with gum cover 33 for its return journey of No. one board 26, No. two board 28 and No. three board 30 in the process of extrapolating can not get into the polishing sand, thereby makes No. one board 26, No. two board 28 and No. three board 30 can normally return to initial position, avoids influencing the reset of No. one board 26, No. two board 28 and No. three board 30 because of the blockking of polishing sand.
