[0039] The power assembly includes the second motor 26, the outside of which is fixedly connected to the inner wall of the square box 25. The second motor 26 serves as the power source of the power assembly. A rotating shaft 27 is fixedly connected to the driving end of the second motor 26.

The outside of multiple limiting blocks 37 are all slidably connected to the inside of the sliding column 29. The limiting blocks 37 can limit the movement range of the sliding column 29 to ensure the stable and reliable movement of the grinding head 31. The left side of the power assembly is fixedly connected to the fixed column 28. The inner wall of the fixed column 28 is slidably connected to the sliding column 29. The sliding column 29 is a component connecting the grinding head 31 and the fixed column 28, and it can slide freely on the inner wall of the fixed column 28. Multiple hook-shaped openings 30 are formed on the outer side wall of the sliding column 29. The hook-shaped openings 30 can cooperate with the button 32 to achieve the quick replacement of the grinding head 31;

[0040] The left side of the sliding column 29 is fixedly connected to the grinding head 31. The grinding head 31 is a component for grinding the inner hole of the oil cylinder, and its precision directly affects the processing quality of the inner hole of the oil cylinder.

[0041] Working principle: First, fix the oil cylinder to be processed through the mechanical clamping mechanism 7, close the cover plate 2 to form a relatively enclosed space for the processing window 1. Start motor 1 5 and motor 2 26. Motor 1 5 drives the rotation of the rotating shaft 6, which in turn drives the mechanical clamping mechanism 7 to rotate, causing the oil cylinder fixed on the mechanical clamping mechanism 7 to rotate. At the same time, motor 2 26 drives the rotation of the rotating shaft 27, driving the fixed column 28, and then driving the sliding column 29, thereby driving the grinding head 31 to rotate to grind the inner hole of the oil cylinder. Using the electric guide rail 23, the sliding plate 24 can drive the square box 25 to approach the oil cylinder for grinding. Then, the rotating shaft 6 will also drive the driving wheel 8 to rotate, thereby driving the belt 9 to rotate, and then driving the driven wheel 11 to rotate. The driven shaft 10 is driven to rotate through the driven wheel 11. The driven shaft 10 drives the two connecting plates 12 to rotate, and then drives the push column 13 to rotate. At this time, the push column 13 pushes the elliptical plate 14 to slide up and down reciprocally, and then drives the support plate 15 to push the filter plate 16 to slide up and down, so that the debris and water are quickly separated. Then, the separated debris will return to the inside of the collection box 38 for collection. Then, the water after the process will fall into the inside of the support box 3. At this time, the water pump 18 in the circulation component introduces the filtered waste water through the water inlet pipe 19 and sprays it out from the nozzle 22 through the transport pipe 20 to cool and clean the processing area. Thus, the double recycling of water and debris is completed, and the waste of resources is avoided.

[0042] At the same time, if it is necessary to replace the grinding head 31, by pushing multiple buttons 32, the buttons 32 will drive the limit ring 36 to slide with the male connection column 33. Here, the connection column 33 drives the disc 34 to slide and compress the strong spring 35, enabling it to provide a reverse force for the button 32 to reset. When the limit ring 36 cannot slide anymore, the grinding head 31 can be rotated clockwise to drive the sliding column 29 to rotate, so that the limit block 37 can be in the long strip area of the hook-shaped opening 30. At this time, the grinding head 31 can be quickly driven to drive the sliding column 29 to disengage from the inside of the fixed column 28, thus completing the rapid disassembly. On the contrary, the new grinding head 31 can be driven to drive the sliding column 29 to be pushed into the inside of the fixed column 28 and rotated counterclockwise. When the force on the button 32 is released, the button 32 drives the limit ring 36 to reset, and then drives the limit block 37 to reset and engage in the short strip area of the hook-shaped opening 30, thus completing the rapid disassembly, enabling the quality of the grinding head 31 to be maintained, thereby improving the working accuracy and the replacement efficiency.
