according to the invention, the flexible polishing shell 2 is influenced by gas pressure to reciprocate on the inner wall of the air cooling pipe 1, so that the inner wall of the air cooling pipe 1 can be polished well, the trouble that a long rotating rod drives a polishing head to move is avoided, the situation that the polishing head excessively polishes at one position is avoided, and the inner wall of the air cooling pipe 1 is polished uniformly and has a small volume;
the flexible polishing shell 2 and the air cooling pipe 1 are matched, the diameter of the flexible polishing shell 2 is slightly larger than the diameter of the inner wall of the air cooling pipe 1, and because the flexible polishing shell 2 has certain flexibility, when the diameter of the flexible polishing shell 2 is slightly larger than the inner diameter of the air cooling pipe 1, the flexible polishing shell 2 can still be plugged into the inner side of the air cooling pipe 1, the flexible polishing shell 2 can slide on the inner side of the air cooling pipe 1, then two sealing covers 9 are used for plugging the two ends of the air cooling pipe 1, the two sealing covers 9 and the air cooling pipe 1 can be relatively fixed by means of a clamping device, for example, an annular or semicircular bracket can be fixed at the moving end of the screw rod and contacted with the outer circle of the sealing covers 9 by means of the semicircular bracket, the sealing covers 9 are pressed, so that the sealing covers 9 are tightly pressed and fixed at the ends of the air cooling pipe 1, the air intake hose 11 is connected with the air pump after the sealing cover 9 is temporarily fixed relatively to the air cooling pipe 1, one of the pressure switches 99 is manually pressed first, the right pressure switch 99 is manually pressed, the right normally closed electromagnetic valve 102 is electrified after being pressed, the normally closed electromagnetic valve 102 is opened, high-pressure air in the air pump enters the inner side of the air intake pipe 10 through the right air intake hose 11 at the moment, when the high-pressure air enters the inner side of the right air intake pipe 10, the high-pressure air pushes the right moving column 12 to move leftwards until the moving column 12 moves into the expansion section of the air intake pipe 10, at the moment, the high-pressure air of the air intake pipe 10 can pass through the expansion section of the air intake pipe 10 without being limited by the moving column 12, the high-pressure air at this time enters the inner side of the air-cooled tube 1, in the process, when the moving column 12 is subjected to the influence of the air pressure to move, the inclined surface of the moving column 12 can squeeze the top end of the push rod 15, so that the push rod 15 is forced to move downwards, the spring seat 16 is driven to move downwards against the elastic force of the third tension spring 17, the push rod 15 can drive the second sealing plate 18 to move downwards so as to seal the drain tube 93 on the left side, before the moving column 12 on the right side completely moves to the expansion section of the right side air inlet tube 10, the push rod 15 is contacted with the bottom end of the moving column 12, that is, before the moving column 12 on the right side can open the passage of the air inlet tube 10 on the right side, the drain tube 93 on the right side is sealed by the second sealing plate 18, so that the inner space of the air-cooled tube 1 between the right side and the sealing cover 9 on the right side of the flexible polishing shell 2 is in a state where only air can not be discharged, and the left side of the left side normally-closed electromagnetic valve 102 does not open the passage, and the drain tube 93 on the left side can not be caused to move, so that the drain tube 93 on the left side can be driven by the left side of the flexible shell 2 is driven by the air, and the left side of the flexible shell 2 can not be discharged by the air when the air is driven by the air from the left side of the flexible shell 2, and the flexible shell 2 is in a state, and the flexible shell 2 is not subjected to the air-cooled;
the protruding limiting angle 103 is provided on the lower matching plate 101, and the distance of the moving column 12 can be limited by the provided limiting angle 103, so that the moving column 12 can be prevented from moving excessively, and the moving column 12 can stay at the expansion section of the air inlet pipe 10;
still further describing the case that the flexible grinding shell 2 moves from right to left, when the flexible grinding shell 2 moves from right to left, the moving power of the flexible grinding shell 2 is provided by the air pressure, when the high-pressure air enters the inner side of the air cooling pipe 1 on the right side of the flexible grinding shell 2, the high-pressure air pushes the movable plate 19 on the right side of the flexible grinding shell 2 to move leftwards against the elastic force of the fourth tension spring 20, so that the movable plate 19 is not used for blocking the opening on the right side of the flexible grinding shell 2, the air can enter the flexible grinding shell 2 from the opening on the right side of the flexible grinding shell 2, because the diameter of the movable plate 19 is larger than that of the opening of the flexible grinding shell 2, the two movable plates 19 on the left side and the right side can only move towards the inner side of the flexible grinding shell 2, and when the air enters the opening on the right side of the flexible grinding shell 2, the air inside the flexible polishing shell 2 can push the sealing slide block 5 to move from right to left, the gap between the supporting shells 4 can be filled by the arranged first sealing plate 8, so that when the sealing slide block 5 moves, certain air tightness can be realized, when the sealing slide block 5 moves to the position of the flexible ring 3, as the left side and the right side of the first sealing plate 8 are both provided with inclined planes, the inclined planes of the first sealing plate 8 are in contact with the flexible ring 3, the first sealing plate 8 can be forced to move towards the inside of the sealing slide block 5, the first sealing plate 8 overcomes the elastic force of the compression spring 81 to move, when the first sealing plate 8 moves to the inside of the sealing slide block 5, the sealing slide block 5 can move to the position of the left supporting shell 4, so that the left supporting shell 4 is spread to be cylindrical, and when the right supporting shell 4 is not supported by the sealing slide block 5, the free end of the supporting shell 4 is affected by the elasticity of the first tension spring 7 to shrink towards the axis of the flexible polishing shell 2, after the supporting shell 4 shrinks, the right part of the flexible polishing shell 2 is not supported by the supporting shell 4, so that the right part of the flexible polishing shell 2 has little extrusion force on the inner wall of the air-cooled tube 1, the flexible ring 3 is made of flexible materials, when the free end of the supporting shell 4 shrinks, the flexible ring 3 cannot interfere with the shrinkage of the free end of the supporting shell 4, the flexible ring 3 does not need to be particularly soft, the flexible ring 3 still has a certain hardness, the hardness is enough to forcefully extrude the inclined surface of the first sealing plate 8, so that the first sealing plate 8 can move towards the inner side of the sealing slide block 5, and when the sealing slide block 5 moves through the flexible ring 3, the first sealing plate 8 is extruded into the inner side of the sealing slide block 5, but the flexible ring 3 is extruded by the elasticity of the compression spring 81, so that the flexible ring 3 is extruded by the elastic force of the compression spring 81, when the flexible ring 3 is extruded by the flexible ring 3, the sealing slide block 3 is stretched out of the sealing slide block 5, and the sealing slide block 4 can be prevented from moving to the inner side of the sealing slide block 5, and the sealing slide block is prevented from moving to the inner side of the sealing slide block 5, and the sealing slide block 8 is deformed relatively to the sealing slide block 4 when the sealing slide block 4 is stretched by the flexible slide block 5, and the sealing slide block 4 is stretched to the inner side by the sealing slide plate 3, and the sealing slide plate 8 is moved to the sealing slide plate 3, and the sealing slide is relatively to the sealing slide 4, and the sealing slide plate 5 is deformed by the sealing slide 5, further, in the process of moving the sealing slide block 5 from right to left, the contact pressure between the left part of the flexible grinding shell 2 and the inner wall of the air-cooling pipe 1 is larger, and the contact pressure between the right part of the flexible grinding shell 2 and the air-cooling pipe 1 is smaller, so that when the flexible grinding shell 2 moves from right to left, the left part of the flexible grinding shell 2 can grind the inner wall of the air-cooling pipe 1, the right part of the flexible grinding shell 2 is mainly used for storing part of ground powdery particles, and because the direction of the drain hole 6 of the right part of the flexible grinding shell 2 is opposite to the moving direction at the moment, the powdery particles easily enter the inner side of the drain hole 6, and at the moment, the contact pressure between the right side of the flexible grinding shell 2 and the air-cooling pipe 1 is smaller, so that the powder particles can better enter the inner side of the drain hole 6, it should be understood that only a part of the powder particles can enter the inner side of the drain hole 6 through the drain hole 6, so that the collection of a part of the powder particles is realized, the powder particles are reduced to remain on the inner wall of the air-cooling tube 1, the polishing effect is improved, all the powder particles cannot enter the inner side of the drain hole 6, the moving stroke of the sealing slide block 5 is influenced by the limiting part 41, and it is required that the supporting shell 4 on the right side is not contacted with the inner wall of the flexible polishing shell 2 at this time, so that the powder particles can enter the inner side of the drain hole 6 and then enter the inner side of the flexible polishing shell 2;
in the process of moving the flexible polishing shell 2 from right to left, the sealing slide block 5 also moves from right to left relative to the flexible polishing shell 2, firstly, the sealing slide block 5 moves from right to left relative to the flexible polishing shell 2, one condition is that after the sealing slide block 5 moves to be in contact with the limiting part 41 on the left supporting shell 4, the limiting part 41 drives the supporting shell 4 to drive the flexible ring 3 to move, the flexible ring 3 moves to drive the flexible polishing shell 2 to move, and the other condition is that before the sealing slide block 5 moves to be in contact with the limiting part 41 on the left supporting shell 4, the sealing slide block 5 presses air on the left side inside the flexible polishing shell 2, so that the air pressure inside the flexible polishing shell 2 and on the left side of the sealing slide block 5 is larger, the flexible polishing shell 2 is directly driven to move to the left under the influence of air pressure, which can be understood that, in the other case, the sealing slide 5 does not directly press the limit portion 41 of the left supporting housing 4, but the high-pressure gas inside the flexible polishing housing 2 and on the left side of the sealing slide 5 is used as a transmission, so that the flexible polishing housing 2 cannot be directly pushed to move, that is, the sealing slide 5 presses the high-pressure gas inside the flexible polishing housing 2 and on the left side of the sealing slide 5, so that the high-pressure gas presses the flexible polishing housing 2 to move leftwards, but the gas pushing the sealing slide 5 to move is still provided by the air pump, the air pump sends the high-pressure gas to the right side of the air cooling tube 1 through the air inlet hose 11 on the right side, the air on the right side of the air cooling tube 1 pushes the movable plate 19 on the right side to enter the inside of the flexible polishing housing 2 and the right side of the sealing slide 5, so as to push the sealing slide 5 to move leftwards, when the support housing 4 is tightly contacted with the inner wall of the flexible grinding housing 2, the support housing 4 can block the drain hole 6 of the flexible grinding housing 2, that is, when the support housing 4 on the left side is tightly contacted with the inner wall of the flexible grinding housing 2, the support housing 4 can block the drain hole 6 on the left side on the flexible grinding housing 2, so that the inside on the left side of the flexible grinding housing 2 is in a sealed state, when the sealing slide block 5 moves leftwards relative to the flexible grinding housing 2, the sealing slide block 5 can squeeze the air in the left side of the flexible grinding housing 2, so that the air in the inside of the flexible grinding housing 2 and at the left side of the sealing slide block 5 has a certain pressure, and it is understood that the flexible grinding housing 2 can move leftwards because the air inlet hose 11 positioned on the right side inputs the air from the right end of the air cooling pipe 1, so that the flexible polishing shell 2 can be pushed to move leftwards, the air pressure in the air cooling tube 1 and on the right side of the flexible polishing shell 2 can push the flexible polishing shell 2 to move leftwards, but in the work of moving the flexible polishing shell 2 leftwards, the sealing sliding block 5 needs to move leftwards relative to the flexible polishing shell 2, because the sealing sliding block 5 is positioned on the inner side of the left supporting shell 4 at the moment, the left supporting shell 4 can seal the left drain hole 6, meanwhile, the left supporting shell 4 can apply a certain pressure on the left part of the flexible polishing shell 2, so that the left part of the flexible polishing shell 2 is tightly contacted with the inner wall of the air cooling tube 1, the flexible polishing shell 2 is added to move relative to the air cooling tube 1 on the premise that the left part of the flexible polishing shell 2 is tightly contacted with the inner wall of the air cooling tube 1, the left side part of the flexible polishing shell 2 can polish the inner wall of the air-cooled tube 1, and the tightness between the left side part of the flexible polishing shell 2 and the inner wall of the air-cooled tube 1 can be improved, when the high-pressure gas inside the air-cooled tube 1 pushes the flexible polishing shell 2 to move leftwards, the flexible polishing shell 2 can have a better moving effect, and the high-pressure gas on the right side of the flexible polishing shell 2 is prevented from penetrating through the flexible polishing shell 2 to enter the left side position of the flexible polishing shell 2;
it should be noted that, when the flexible polishing housing 2 is moved to the leftmost position of the air cooling tube 1 and cannot be moved continuously, the high-pressure gas needs to be stopped to be continuously input to the air inlet hose 11 on the right side, and the drain pipe 93 on the right side is in a passage state according to the above principle, because the sealing slide block 5 is located at the inner side of the support housing 4 on the left side, but the support housing 4 on the right side is not in contact with the drain hole 6 on the right side of the flexible polishing housing 2, that is, the drain hole 6 on the right side of the flexible polishing housing 2 is not blocked, and the flexible polishing housing 2 has a certain flexibility, and the contact pressure between the right side of the flexible polishing housing 2 and the inner wall of the air cooling tube 1 is not large, so that the high-pressure gas in the inside of the flexible polishing housing 2 and the right side of the sealing slide block 5 can be discharged through the drain hole 6 on the right side, but the gas pressure in the inside of the flexible polishing housing 2 and the right side of the sealing slide block 5 can be reduced, thereby creating an advantageous condition for the next rightward movement of the sealing slide block 5 relative to the flexible polishing housing 2, and the influence on the rightward movement of the sealing slide block 5 caused by the high pressure in the inside of the flexible polishing housing 2 is avoided;
when the flexible polishing shell 2 moves leftwards to the maximum travel, the left movable plate 19 is contacted with the left trigger rod 91, so that the left movable plate 19 is pressed by the left trigger rod 91 to move rightwards, the opening of the left side of the flexible polishing shell 2 is opened, at the moment, high-pressure air in the left side of the flexible polishing shell 2 is sprayed outwards through the opening of the left side of the flexible polishing shell 2, high-pressure air in the inner side of the flexible polishing shell 2 enters the inner side of the air cooling tube 1 and then is discharged through the left drain tube 93, and as the first flexible polishing shell 2 moves leftwards and rightwards, powdery particles are not contained in the left side of the flexible polishing shell 2, but the following left and right back movement of the flexible polishing shell 2 can cause the powdery particles to be stored in the inner side of the flexible polishing shell 2, and in the operation of the movable plate 19 pressed by the trigger rod 91, the powdery particles can be discharged from the drain tube 93 along with air flow;
in the process that the flexible polishing shell 2 moves from right to left, the flexible polishing shell 2 extrudes air on the inner side of the left end of the air cooling tube 1, the air on the inner side of the left end of the air cooling tube 1 is finally discharged from the left drain tube 93, when the flexible polishing shell 2 moves to the leftmost position, the air on the inner side of the flexible polishing shell 2 is discharged from the drain tube 93, when the air is discharged from the drain tube 93, the air pushes the circular plate 97 to move, the circular plate 97 drives the connecting support 96 to drive the rotating support 95 to rotate, the rotating support 95 rotates to drive the hammering head 98 to move and press the pressure switch 99, the pressure switch 99 is not energized with the normally closed electromagnetic valve 102 close to the pressure switch 99 when the pressure switch 99 is continuously pressed, the normally closed electromagnetic valve 102 close to the pressure switch 99 is energized after the pressure switch 99 is not pressed for 2-5 seconds, the normally closed electromagnetic valve 102 is opened after the pressure switch 102 is energized, meanwhile, when one of the normally closed electromagnetic valve 102 is opened, the other normally closed electromagnetic valve 102 is immediately energized and the pressure switch 99 is not pressed with the pressure switch 2-5 seconds.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments.
