[0038] A plurality of air blowing holes 717 are provided at equal intervals in the upper and lower parts, and the air blowing holes 717 are located on one side of the polishing portion of the scraper rod 6 .

[0039] Specifically, when the lifting frame 4 starts to move downward, the gas drawn in by the air pump 5 can be sprayed downward to clean up the residue from the previous grinding, and through the reaction force of the gas, it can automatically identify whether the inner cylinder body 2 is placed on the bottom side and automatically start the drive motor 73, which is quick and convenient and does not require manual operation.

[0040] In another embodiment provided by the present invention, the automatic identification mechanism 8 includes an insertion strip 81, one end of the insertion strip 81 is horizontally slidably set in the slider 71, and the other end of the insertion strip 81 is slidably set in the insertion rod 77. The lower side of the insertion strip 81 is located in the slider 71 and is provided with a lower blowing groove 82, a second guide groove 84 and a third guide groove 811. The bottom end of the lower blowing groove 82 is connected to the outside of the slider 71, the bottom end of the second guide groove 84 is connected to the second ring groove 712, and the bottom end of the third guide groove 811 is connected to the first ring groove 711. The upper side of the insertion strip 81 is located in the slider 71 and is provided with an air storage chamber. 83, the upper side of the air storage chamber 83 is connected to the conduit 76, the lower side of the insertion strip 81 is located in the slider 71 and is fixed with a magnetic block 85, the bottom end of the insertion strip 81 is movably inserted with a movable column 86, a through hole is opened in the movable column 86, and a connecting pipe 87 is connected between the upper end of the movable column 86 and the air storage chamber 83, one side of the movable column 86 is located in the slider 71 and is slidable up and down with a conductive block 88, one side of the upper end of the conductive block 88 is located in the slider 71 and is fixed with a friction pad 89, and the other side of the upper end of the conductive block 88 is located in the slider 71 and is provided with a conductive block 810.

[0041] The conductive block 810 is electrically connected to a switch that controls the driving motor 73 .

[0042] The magnetic block 85 can attract the conductive block 88 .

[0043] Specifically, when the lifting frame 4 continues to move downward, the gas can automatically jet clean the inner wall of the inner cylinder body 2 before and after grinding, and the inner cylinder bodies 2 of various inner diameters can be ground by the force of the gas without replacing another grinding head.

[0044] Working principle: When using the device, first adjust the position of each slider 71 through the locking bolt 75, then place the inner cylinder body 2 directly under the slider 71, and then start the air pump 5. The air pump 5 draws external air into the device. The air passes through the conduit 76, the air storage chamber 83, the connecting pipe 87, the movable column 86 and the lower blowing groove 82, and is ejected from the lower side of the slider 71. The downwardly ejected gas can clean the residue from the last grinding. Then start the cylinder 3 to move the lifting frame 4 and the slider 71 downward. If the lower part of the lower blowing groove 82 is aligned with the upper horizontal surface of the inner cylinder body 2, the upward reaction force on the side movable column 86 is greater, and the movable column 86 will automatically move upward. Thereby, the conductive block 88 is pushed upward. After the conductive block 88 moves to the friction pad 89, the conductive block 88 will not fall downward due to the friction force of the friction pad 89. The conductive block 88 contacts the two conductive blocks 810, so that the conductive blocks 810 are energized, and the drive motor 73 on the corresponding slider 71 is automatically started to carry out the subsequent grinding. On the contrary, if the inner cylinder body 2 is not set directly below the lower blowing groove 82, the upward reaction force on the movable column 86 is small, and the conductive block 810 will not start. The reaction force of the gas can automatically identify whether the inner cylinder body 2 is placed on the bottom side and automatically start the drive motor 73. It is fast and convenient and does not require manual operation.

[0045] The lifting frame 4 continues to move downward, and then the inclined surface 79 on the insertion rod 77 will be squeezed by the squeezing block 72, and the insertion rod 77 will drive the insertion bar 81 to move toward the center of the rotating block 710. The insertion bar 81 will drive the movable column 86 to correspond to the second guide groove 84 and the third guide groove 811 in sequence, so that the gas first passes through the second guide groove 84, the second ring groove 712 and the first guide groove 716, and finally is ejected from the blowing hole 717, which can clean the inner wall of the inner cylinder body 2. After that, after the scraper rod 6 is fully inserted into the inner cavity of the inner cylinder body 2, the gas passes through the third guide groove 811 and the first ring groove 711 into the sliding cavity 714, so that the slide 713 is pushed, and the polishing part of the scraper rod 6 can also be It fits tightly against the inner cavity of the inner cylinder body 2, so that it can adapt to inner cylinder bodies 2 of various inner diameters. After grinding is completed, the lifting frame 4 is moved upward, and the guide groove 2 84 will be connected to the through hole in the movable column 86 again. The gas will be ejected again through the blowing hole 717 to prevent the grinding debris from adhering to the inner wall of the inner cylinder body 2. Then the conductive block 88 moves to the top of the magnetic block 85, the conductive block 88 is adsorbed and moves downward, and the conductive block 88 is reset. Through the push of gas, it can grind inner cylinder bodies 2 of various inner diameters, and the inner wall of the inner cylinder body 2 can be automatically cleaned by jet before and after grinding. There is no need to replace the grinding head, and the cleaning is more efficient.
