[0002] The cylinder liner is short for the engine cylinder liner, which is inserted into the cylinder barrel of the cylinder block and jointly forms a combustion chamber with the piston and the cylinder head. The cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. The cylinder liner whose back does not contact the cooling water is called a dry cylinder liner, and the cylinder liner whose back contacts the cooling water is a wet cylinder liner. The dry cylinder liner has a thinner thickness, a simple structure, and is convenient for processing. The wet cylinder liner is directly in contact with the cooling water, so it is beneficial to the cooling of the engine and the miniaturization and light weight of the engine.

[0019] The detailed connection means is well-known technology in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] In the present utility model, the electric telescopic rod 4, the first motor 6, the second motor 17, the third motor 24, the first cylinder 11 and the second cylinder 21 are all connected to an external electric control system through wires. The above devices and connection methods are all prior arts and will not be elaborated here too much.

[0021] According to the attached Figure 1 description, it can be known that when the present utility model is in use, first, the cylinder liner is vertically arranged between a pair of fixing components on the turntable 10, and the cylinder liner is clamped and fixed by the pair of fixing components. After the cylinder liner is firmly fixed, its hollow part is located above the through groove. Secondly, start the grinding component arranged on the first connecting plate 5, and start the electric telescopic rod 4. The telescopic end of the electric telescopic rod 4 drives the first connecting plate 5 to move vertically downward, so that the grinding component is embedded into the cavity of the cylinder liner. Then, adjust the horizontal positions of the electric telescopic rod 4 and the grinding component through the horizontal driving component, so that the grinding piece in the grinding component contacts the inner wall of the cylinder liner for grinding. Thirdly, start the second motor 17 arranged on the side plate 2. The second motor 17 drives the gear 18 connected to its output end to rotate. The gear 18 drives the meshing ring gear 16 to rotate. The ring gear 16 drives the connecting ring 13 to rotate. The connecting ring 13 drives the turntable 10 to rotate. The turntable 10 drives a pair of fixing components to rotate. The pair of fixing components drive the cylinder liner to rotate, so as to adjust the circumferential position of the cylinder liner during grinding. During the grinding process, the horizontal driving component and the electric telescopic rod 4 respectively adjust the horizontal and vertical positions of the grinding component. The debris generated during grinding falls out through the through grooves opened on the turntable 10 and the workbench 1; after grinding is completed, provide cleaning liquid to the liquid outlet component on the first connecting plate 5. The cleaning liquid is sprayed onto the inner wall of the cylinder liner through the liquid outlet component. During the cleaning process, the horizontal driving component and the electric telescopic rod 4 also adjust the horizontal and vertical positions of the liquid outlet component to ensure that the inner wall of the cylinder liner can be comprehensively cleaned. The cleaning liquid sprayed onto the inner wall of the cylinder liner and the impurities also flow out through the through groove; the present utility model adjusts the vertical height of the first connecting plate 5 through the electric telescopic rod 4, and adjusts the horizontal position of the first connecting plate 5 through the horizontal driving component. When the first connecting plate 5 moves, it drives the grinding component and the liquid outlet component to move, ensuring the comprehensive and thorough grinding of the inner wall of the cylinder liner and the cleaning after grinding. After grinding is completed, cleaning can be carried out without using other equipment, simplifying the processing flow and saving the cost of additional cleaning equipment.

[0022] There is a possible implementation. When the output end of the third motor 24 rotates, the output end of the third motor 24 drives the connected threaded rod 25 to rotate. The threaded rod 25 drives the slidably connected slider 26 to slide horizontally in the chute. The slider 26 drives the electric telescopic rod 4 arranged at the bottom to move, thereby enabling the third motor 24 to adjust the horizontal position of the electric telescopic rod 4.

[0023] There is a possible implementation. When the output end of the first motor 6 rotates, it drives the grinding roller 9 connected thereto and rotatably arranged on the first connecting plate 5 and the third connecting plate 8 to rotate. The grinding roller 9 abuts against the inner wall of the cylinder liner to grind the inner wall of the cylinder liner.

[0024] There is a possible implementation. When starting the liquid supply device, the liquid supply device injects cleaning liquid into the water outlet pipe 28 through the connecting hose 27, and the cleaning liquid then sprays out from the plurality of nozzles 29 to clean the inner wall of the cylinder liner.

[0025] There is a possible implementation. A limiting ring 14 is arranged on the outer wall of the connecting ring 13 and below the gear ring 16. A limiting groove body 15 is arranged on the workbench 1. The limiting ring 14 is rotatably arranged in the limiting groove body 15, and the limiting groove body 15 limits the limiting ring 14 to prevent the turntable 10 from shifting during rotation.

[0026] There is a possible implementation. When grinding the inner wall of the cylinder liner, the second cylinder 21 on one side (such as the right side) is started. The second cylinder 21 drives the sealing plate 22 connected to its telescopic end to move obliquely upward (such as the upper right). The metal chips generated during grinding first fall into the collection box 19 through the through grooves opened on the turntable 10 and the workbench 1, then slide right downward on the left sealing plate 22 and the angular plate 20, and finally are discharged from the discharge pipe 23 on the right side; when cleaning the inner wall of the cylinder liner, the second cylinder 21 on the right side drives the right sealing plate 22 to reset, and the second cylinder 21 on the left side drives the left sealing plate 22 to move obliquely upward to the left. The cleaning liquid with impurities flows from the through groove onto the right sealing plate 22 and the angular plate 20, and then is discharged from the discharge pipe 23 on the left side, realizing the classified recovery of the cleaning liquid and the metal chips.

[0027] There is a possible implementation. When fixing the cylinder liner, a pair of first cylinders 11 drive a pair of clamping plates 12 to move towards each other, and the pair of clamping plates 12 clamp and fix the cylinder liner. During grinding or cleaning, the second motor 17 can drive the cylinder liner to rotate 180 degrees in one direction and then reset, and then rotate 180 degrees in the reverse direction to prevent the air supply pipe of the first cylinder 11 from being wound. The fixing assembly can also use bolts threadedly connected to the shaft seat to fix the cylinder liner.
