[0040] The working principle and usage process of this utility model are as follows: During use, the user places the oil cylinder to be ground on top of the roller 9, then starts the cylinder 16, causing the output end of the cylinder 16 to drive the support block 17 and the pressure roller 18 downwards, so that the pressure roller 18 presses and positions the oil cylinder pipe at the top of the roller 9. Then, the user rotates the sealing cover 14 counterclockwise to disengage it from the water tank 101. Next, the user pours coolant into the water tank 101. At this time, the user starts the electric slide rail 2 and the motor 3. The electric slide rail 2 drives the motor 3, the hollow tube 4, and the grinding wheel 5 to move to the left.

The coolant inside 101 is delivered to the inside of the distributor pipe 103, the heat dissipation pipe 104, and the connecting pipe 105a, so that the coolant and the heat dissipation pipe 104 can dissipate heat from the motor 3. The coolant inside the connecting pipe 105a enters the inside of the hollow pipe 4 through the ring 105b and the water inlet hole, and then sprays the oil cylinder being polished by the grinding wheel 5 through the drain hole to cool it down. At this time, the oil cylinder can be cooled. At this time, the coolant is delivered to the inside of the collection box 112 through the collection cover 6 and the pipe 111. Then, the dust bag 20 filters the dust in the coolant. Then, the user starts the second water pump 113. The output end of the second water pump 113 delivers the filtered coolant to the inside of the hose 114. Then, the hose 114 delivers the coolant back to the inside of the water tank 101 for recycling.

[0041] In summary, this grinding device for hydraulic cylinder processing uses cylinder 16 and pressure roller 18 to press and position the hydraulic cylinder. After positioning, the rotating grinding wheel 5 grinds the inside of the hydraulic cylinder. Then, the cooling mechanism 10 sprays coolant into the inside of the hydraulic cylinder to cool it down. This solves the problem that the grinding device cannot cool the hydraulic cylinder during use, and the excessively high temperature of the hydraulic cylinder will cause deformation due to thermal expansion and contraction.
