[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] Embodiment 1: A magnesium alloy engine cylinder block grinding device: comprising a base 1, a vertical column 2 and a collecting table 3, wherein the collecting table 3 is mounted on the top of the base 1, the vertical column 2 is mounted on one side of the top of the base 1, and a top frame 21 is mounted on the top of the vertical column 2;

[0030] The rotational grinding unit for the inner wall of the cylinder block of the engine cylinder is arranged above the top frame 21 and is used to grind the inner wall of the cylinder block of the engine cylinder placed on the top of the collecting platform 3;

[0031] The rotational grinding unit for the inner wall of the engine cylinder block includes a grinding part, which includes a hydraulic telescopic cylinder 22. The hydraulic telescopic cylinder 22 is installed on the top of the top frame 21. A mounting frame 4 is installed on the output end of the hydraulic telescopic cylinder 22. Independent drive rollers 41 are embedded in the surface of the mounting frame 4. The independent drive rollers 41 are arranged in several groups at intervals. A grinding bin 42 is installed on the rotating end of the independent drive roller 41, and the surface of the grinding bin 42 is provided with a wear-resistant coating.

[0032] A central column 44 is installed inside the grinding chamber 42, and a limit frame 45 is installed on the outer surface of the central column 44. The limit frames 45 are arranged in four groups. An expansion cylinder 46 is installed inside the limit frame 45. A slider 47 is installed on the movable end of the expansion cylinder 46. A pressure guard plate 48 is installed on one side of the slider 47. A gap cavity 43 is provided between the surface of the pressure guard plate 48 and the inner wall of the grinding chamber 42.

[0033] The rotational grinding unit for the inner wall of the engine cylinder block also includes a lubrication part, which includes a side spray bin 6. The side spray bin 6 is symmetrically arranged in two groups. The two groups of side spray bins 6 are symmetrically installed on both sides of the mounting frame 4. Multiple groups of side spray heads 61 are installed at intervals on the surface of the side spray bin 6. Each group of side spray heads 61 is set to two, and each group of side spray heads 61 is tilted and symmetrically arranged.

[0034] In this embodiment, the independent drive roller 41 rotates to drive the grinding chamber 42 to rotate and insert into the inner wall of the magnesium alloy engine cylinder. When the inner wall of the grinding chamber 42 contacts the inner wall of the magnesium alloy engine cylinder, it will smoothen the brushed area of ​​the inner wall surface of the cylinder. During the grinding process, the cleaning liquid sprayed obliquely by the lateral nozzle 61 can reduce the friction of the inner wall of the cylinder, further improving the grinding and repair effect of the inner wall of the magnesium alloy engine cylinder.

[0035] A collecting chamber 31 is provided inside the collecting platform 3 , and polishing lubricating liquid filtering, recycling and reflux units are provided on both sides of the collecting chamber 31 .

[0036] The polishing lubricant filtration recovery and reflux unit includes an adsorption part, which includes a magnetic filter 32 installed inside the collection chamber 31. A magnetic adsorption column 33 is installed at the bottom of the collection chamber 31, and the magnetic adsorption column 33 is arranged in several groups at intervals.

[0037] The grinding lubricating liquid filtering, recovery and reflux unit also includes a reflux part, which includes a side storage bin 7. The side storage bin 7 is set into two groups. The two groups of side storage bins 7 are symmetrically installed on both sides of the collection platform 3. The side storage bin 7 is connected to the inside of the collection chamber 31. A delivery hose 62 is installed on the top of the side storage bin 7, and one end of the delivery hose 62 is connected to the side spray bin 6.

[0038] In this embodiment, the magnetic adsorption column 33 will adsorb and filter the metal chip powder that the magnetic filter screen 32 cannot filter. The recovered lubricating liquid can then be recovered outward through the side storage bin 7 and re-injected into the side spray bin 6 through the delivery hose 62 installed on the top of the side storage bin 7, thereby reducing the loss of lubricating liquid and reducing the cost of grinding and repairing the inner wall of the magnesium alloy engine cylinder.

[0039] Working principle: When using this device, the operator first lifts the magnesium alloy engine cylinder block and places it on the top of the collection platform 3, then fixes the magnesium alloy engine cylinder block on the top of the collection platform 3, and then the operator calibrates the placement height of the mounting frame 4 through the hydraulic telescopic cylinder 22. Then the operator supplies cleaning liquid to the side spray head 61 area through the side spray bins 6 set on both sides of the mounting frame 4. The side spray heads 61 are symmetrically arranged at an angle. The cleaning liquid sprayed by the side spray heads 61 at an angle can effectively flush away the carbon deposits and impurities remaining on the inner wall of the magnesium alloy engine cylinder block, thereby reducing the wear of the inner wall of the cylinder block during the subsequent grinding process of the magnesium alloy engine cylinder block and improving the grinding and repair effect of the inner wall of the magnesium alloy engine cylinder block.

[0040] After the inner wall of the magnesium alloy engine cylinder is flushed and pre-treated, the operator operates the hydraulic telescopic cylinder 22 to descend, and the moving end of the hydraulic telescopic cylinder 22 drives the mounting frame 4 to partially descend, and then drives the independent driving roller 41 at the bottom of the mounting frame 4 to rotate. The rotation of the independent driving roller 41 drives the grinding chamber 42 to rotate and insert into the inner wall of the magnesium alloy engine cylinder. When the inner wall of the grinding chamber 42 contacts the inner wall of the magnesium alloy engine cylinder, the brushed area of ​​the inner wall surface of the cylinder is smoothed and polished. During the polishing process, the cleaning liquid sprayed obliquely by the side nozzle 61 can reduce the friction of the inner wall of the cylinder, further improving the polishing and repair effect of the inner wall of the magnesium alloy engine cylinder;

[0041] During the grinding process, the side nozzle 61 sprays lubricating liquid onto the inner wall area of ​​the magnesium alloy engine cylinder. The lubricating liquid flows into the inner wall of the magnesium alloy engine cylinder and then flows out through the pores on both sides of the cylinder surface. The lubricating liquid flows into the collection chamber 31 through the top of the collection table 3. When the lubricating liquid passes through the magnetic filter 32, the magnetic filter 32 will block and filter the metal chips generated by grinding. Then the lubricating liquid flows into the bottom of the collection chamber 31. The bottom of the collection chamber 31 is also equipped with a magnetic adsorption column 33. The magnetic adsorption column 33 will adsorb and filter the metal chip powder that cannot be filtered by the magnetic filter 32. Then the recovered lubricating liquid can be recovered outward through the side storage bin 7 and re-injected into the side spray bin 6 through the delivery hose 62 installed on the top of the side storage bin 7, thereby reducing the loss of lubricating liquid and reducing the cost of grinding and repairing the inner wall of the magnesium alloy engine cylinder.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
