When the second gear ring rotates, it can drive multiple second connecting rods to rotate and push multiple clamping blocks to move closer to each other, so that the cylinder head body can be clamped and fixed in the center. Then, the oil cylinder is started to drive the first moving block to move. When the first moving block abuts against the end of the sliding ring, it can push the moving plate to move, thereby driving the two cylinder head bodies to move in the direction close to the cylinder body.

Then, the two ends of the air pipe can be inserted into the connecting hole of the cylinder head body, and then the solenoid valve is opened to observe whether there are bubbles in the soapy water, so that after the press-fitting is completed, it is convenient to detect the sealing, which is more convenient and quick to use, and the quality of the installation is guaranteed. After the detection is completed, when the first moving block abuts against the end of the first T-shaped guide rod, it can drive the two moving plates to move away from each other and reset. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Working principle: When the cylinder head body 14 needs to be installed, the cylinder body 13 is first placed on the arc block 1103, and then the first motor 803 is started. The rotation of the first motor 803 drives the rotation of the first gear 804, thereby driving the first gear ring 801 to rotate. When the first gear ring 801 rotates, it can drive the multiple first connecting rods 805 to rotate and push the multiple arc blocks 1103 to move closer to each other, so that the cylinder body 13 can be clamped in the center, and the first gear ring 801 can rotate. A ball 1104 contacts the side wall of the cylinder body 13. Then, the cylinder head body 14 is placed on the clamping block 1203 and fits with the stopper 1204. The second motor 903 is started. The rotation of the second motor 903 drives the rotation of the second gear 904, thereby driving the second gear ring 901 to rotate. When the second gear ring 901 rotates, it can drive the multiple second connecting rods 905 to rotate and push the multiple clamping blocks 1203 to move closer to each other, so that the cylinder head body 14 can be clamped and fixed in the center.

[0046] Then, the oil cylinder 1205 is started to drive the first moving block 1206 to move, and the first push plate 502 is first driven to move through the moving plate 1207, and the push block 504 slides along the inclined surface 503 to the top of the first push plate 502, thereby pushing the U-shaped plate 1501 to move upward. At the same time, the third spring 604 is compressed. When the U-shaped plate 1501 moves upward, it can drive the two moving columns 1502 to move upward synchronously. When the tapered rod 1503 abuts against the side wall of the cylinder cover body 14, it can push the tapered rod 1503 to move in the direction close to the moving column 1502. At the same time, the first spring 1003 is compressed. When the second ball 1504 and the sealing ring 1 When the side walls of the first and second springs 1503 abut against each other, the first spring 1003 can be pushed to continue to be compressed, thereby moving the second ball 1504 to the end of the boss 1401. At the same time, under the action of the return spring 1506, the tapered rod 1503 can slide along the side wall of the boss 1401, so that the second ball 1504 slides on the end of the sealing ring 1402, thereby squeezing the sealing ring 1402 to ensure that the sealing ring 1402 is installed in place. After the squeezing is completed, the two tapered rods 1503 can move to the top of the cylinder head body 14 to ensure the subsequent normal press-fitting operation, thereby ensuring that the sealing ring 1402 is installed in place before the press-fitting, thereby ensuring the quality after installation;

[0047] When the first moving block 1206 abuts against the end of the sliding ring 402, the moving plate 1207 can be pushed to move, thereby driving the two cylinder head bodies 14 to move in the direction close to the cylinder body 13. When the boss 1401 abuts against the cylinder body 13, the second spring 403 can be compressed, and the distance from the moving plate 1207 can be detected by the distance sensor 404 to determine the compression amount of the second spring 403, thereby controlling the pressure during press-fitting, and pressing the boss 1401 into the cylinder body 13. In addition, the system can be applied to cylinders of different specifications and sizes, with stronger applicability, making installation more convenient and quick, and ensuring the quality of installation.

[0048] Furthermore, during press-fitting, when the U-shaped plate 1501 moves upward, the push rod 703 and the second push plate 701 can drive the sliding plate 204 to move synchronously, so that negative pressure is generated in the fixed cover 203. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the soapy water in the liquid storage tank 206 can enter the fixed cover 203 through the liquid extraction tube 205 for temporary storage.

[0049] After the press-fitting is completed, the first moving block 1206 is driven by the oil cylinder 1205 to move and reset. At this time, the first push plate 502 is driven to move and reset through the connecting plate 501, so that the push block 504 can slide from the top of the first push plate 502 to the inclined surface 503 and slide downward along the inclined surface 503. At this time, the U-shaped plate 1501 can move downward and reset under the action of the third spring 604. At this time, the two tapered rods 1503 can slide along the side wall of the cylinder body 13, and the second ball 1504 rolls on the side wall of the cylinder cover body 14. Moreover, when the U-shaped plate 1501 moves upward, the second push plate 701 can be driven downward by the push rod 703, and the sliding plate 204 moves downward, so that the soapy water temporarily stored in the fixed cover 203 can be squeezed, and enters the annular cover 201 through the first hose 207 and the second hose 208, and then is sprayed out at the junction of the cylinder head body 14 and the cylinder body 13 through the spray hole 202. Then, the two ends of the air pipe 303 can be inserted into the connecting hole 1403 of the cylinder head body 14. Then, the solenoid valve 302 is opened, and it is observed whether there are bubbles of soapy water. After the press-fitting is completed, it is convenient to detect the sealing, which is more convenient and quick to use and ensures the quality of installation. After the detection is completed, when the first moving block 1206 abuts against the end of the first T-shaped guide rod 401, it can drive the two moving plates 1207 to move away from each other and reset.
