These problems not only affect the appearance of the castings, but may also affect their subsequent processing and performance. Therefore, effective grinding and treatment of the surface of metal castings is a key step to improve product quality and performance.

[0026] The docking teeth 114 are meshed and connected to the driving gear 109, the rotating gear 317 is meshed and connected to the fixed rack 116, the fixed rack 116 penetrates the sliding base 201, the movable rod 209 is evenly distributed on the rotating ring 206, the connecting track 208 is symmetrically arranged on the rotating ring 206, the movable vertical plate 106 is symmetrically arranged, and the threaded structure on the inner surface of the movable vertical plate 106 is in opposite directions.

[0027] During specific use, the cylindrical metal casting to be processed is placed between the movable vertical plates 106, and the intermediate adjustment motor 104 is started. The intermediate adjustment motor 104 drives the driving screw 105 to rotate, and the driving screw 105 rotates to drive the movable vertical plates 106 to move relatively until the rotating disk 113 contacts the end surface of the cylindrical metal casting. Then, the rotating drive motor 107 is started, and the rotating drive motor 107 drives the driving gear 109 to rotate through the output shaft 108. The driving gear 109 rotates and drives the rotating disk 113 to rotate through the docking teeth 114. The rotating disk 113 rotates through the driving inclined groove 115 and the straight groove 111 to drive the movable clamping block 112 to move synchronously along the driving inclined groove 115 and the straight groove 111, so that the movable clamping block 112 clamps and fixes the cylindrical metal casting.

[0028] Then, the limit block 319 is manually controlled to move along the movable slide groove 318. As the limit block 319 moves, the limit tooth 2 321 set on the limit block 319 separates from the limit tooth 1 306. At this time, the angle of the support rod 307 can be freely adjusted. The angles of the support rod 307 and the docking block 308 are manually adjusted so that the upper surface of the docking block 308 fits tightly with the outer surface of the cylindrical metal casting. After the docking block 308 is adjusted, the limit block 319 is released. The limit block 319 is reset along the movable slide groove 318 under the action of the support spring 320. At this time, the limit block 319 contacts the connecting shaft 305 again, the limit tooth 2 321 re-engages the limit tooth 1 306, and the angle of the support rod 307 is fixed again.

[0029] At the same time, the movable rod 209 is displaced under the action of the adjusting spring 210, so that the grinding wheel 211 set on the movable rod 209 moves to the outer surface of the cylindrical metal casting, and then the power output motor 202 is started, and the power output motor 202 drives the driving gear 203 to rotate, and the driving gear 203 drives the rotating ring 206 to rotate through the fixed latch 207, and the rotating ring 206 drives the movable rod 209 to rotate. The direction in which the rotating ring 206 drives the movable rod 209 to rotate is perpendicular to the direction in which the movable rod 209 is displaced, so that the movable rod 209 will not be displaced when rotating, so that the grinding wheel 211 effectively grinds the outer surface of the cylindrical metal casting, and the displacement drive motor 310 is started, and the displacement drive motor 310 drives the driving pulley 313 to rotate, and the driving pulley 313 drives the driven pulley 314 to rotate through the transmission belt 315. The wheel 314 drives the rotating gear 317 to rotate through the transmission shaft 316. The rotating gear 317 rotates through the fixed rack 116 to drive the sliding base 201 to move on the upper surface of the mounting base 101. As the sliding base 201 moves, the docking block 308 slides on the outer surface of the cylindrical metal casting. When the outer surface of the cylindrical metal casting is relatively rough, the resistance encountered by the docking block 308 during displacement is relatively large. At this time, the docking block 308 drives the movable mounting frame 302 to squeeze the reset spring 303 for displacement through the support rod 307. The movable mounting frame 302 drives the control rod 304 to move. The control rod 304 toggles the adjustment controller 311 to squeeze the telescopic spring 312. The displacement of the adjustment controller 311 reduces the rotation speed of the displacement drive motor 310, thereby reducing the moving speed of the sliding base 201 and extending the grinding time of the grinding wheel 211 on the cylindrical metal casting.

[0030] After the sliding base 201 moves to the other end of the cylindrical metal casting, the displacement drive motor 310 rotates in the opposite direction, driving the sliding base 201 to reset. During the resetting process of the sliding base 201, the movable mounting frame 302 is reset. The reset of the movable mounting frame 302 drives the displacement drive motor 310 to reset to the initial position, so that the rotation speed of the displacement drive motor 310 is restored, and the sliding base 201 is reset at a faster speed. Then the displacement drive motor 310 rotates in the opposite direction again. At this time, the roughness of the outer surface of the cylindrical metal casting is improved. When the sliding base 201 is displaced for the second time, the resistance encountered by the docking block 308 is reduced. At this time, the speed reduction amplitude of the displacement drive motor 310 is reduced, and the grinding is repeated until the impurities on the outer surface of the cylindrical metal casting are cleaned up. The above is the overall workflow of the present invention. Just repeat this step when using it next time. The actual operation process is very simple and easy.
