[0003] The utility model with the authorization publication number CN214923119U provides a vehicle engine casing polishing device, which belongs to the "automobile" technical field, and the protected claim: "including a box body, a polishing mechanism is provided inside the box body, the polishing mechanism is connected to a driving mechanism, and a clamping mechanism is also provided inside the box body; the polishing mechanism is used for polishing the surface of the engine casing; the driving mechanism is used to drive the polishing mechanism to move in multiple directions; the clamping mechanism is used to fix the engine casing. The device polishes the engine casing through the polishing mechanism, wherein the polishing mechanism is connected to a driving mechanism, and the polishing mechanism is driven to move by the driving mechanism, so that the polishing mechanism can perform multiple-direction polishing on the engine casing, the polishing area is wide, no manual operation is required, and the efficiency is high.

[0033] Embodiment 2

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, the moving component 3 includes a third hydraulic rod 31, a third motor 35 and a moving block 37; the third hydraulic rod 31 is fixedly connected to the frame 15, and the driving end of the third hydraulic rod 31 is fixedly connected to the moving plate 32, two sliding grooves 33 are provided on the frame 15, and the bottom of the moving plate 32 is slidably connected to the two sliding grooves 33, and an empty groove 34 is provided in the moving plate 32; the third motor 35 is fixedly connected to one end of the moving plate 32, and the driving end of the third motor 35 extends into the empty groove 34 and is fixedly connected to a screw rod 36; the moving block 37 is threadedly sleeved on the outside of the screw rod 36.

[0035] During specific implementation, the third hydraulic rod 31 is started to drive the movable plate 32 to move linearly in the X-axis direction under the limiting action of the slide groove 33, that is, the grinding assembly 38 is driven to move linearly in the X-axis direction, and then the third motor 35 is started. The third motor 35 drives the screw 36 to rotate, and then drives the movable block 37 to move linearly in the Y-axis direction, that is, the grinding assembly 38 is driven to move linearly in the Y-axis direction. In this way, the grinding assembly 38 can be driven to move at any position in the device through cooperation with the hydraulic cylinder 14.

[0036] like Figure 2 As shown, further, the grinding assembly 38 includes a connecting plate 381 and a grinding wheel 384; the connecting plate 381 is fixedly connected to the bottom end of the moving block 37, one side of the connecting plate 381 is fixedly connected to a fourth hydraulic rod 382, ​​the driving end of the fourth hydraulic rod 382 is rotatably connected to a rotating plate 383, and the bottom end of the rotating plate 383 is rotatably connected to the bottom end of the connecting plate 381; the grinding wheel 384 is fixedly arranged on one side of the rotating plate 383.

[0037] During specific implementation, when grinding the side of the machine body, it is necessary to start the fourth hydraulic rod 382, ​​and the fourth hydraulic rod 382 drives the rotating plate 383 to rotate to 90 degrees, so that the side of the machine body can be grinded. In addition, it should be noted that the driving end of the fourth hydraulic rod 382 is rotatably connected to a rotating block, and a groove is provided on one side of the rotating plate 383.

After the upper end surface of the body is polished, start the two opposite first hydraulic rods 212 to drive the two opposite first clamping plates 213 to release the clamping of the body. At this time, only the two opposite first hydraulic rods 212 are left to clamp the two sides of the body, and then start the two opposite first motors 211. The two opposite first motors 211 drive the two first hydraulic rods 212 to rotate, thereby driving the body to move forward. The machine body is rotated, and at the same time, the grinding assembly 38 grinds the machine body, so that only two side surfaces of the machine body are not grinded. At this time, the other two opposite first hydraulic rods 212 are started to clamp the two side surfaces of the machine body that have been grinded, and the remaining two first hydraulic rods 212 release the clamping of the machine body, and then the grinding assembly 38 is started again, so that all surfaces of the machine body can be grinded without manual direction change. If the clamping is unstable, the second hydraulic rod 222 can be started to drive the connecting rod 223 and the second clamping plate 224 and the upwardly arranged first clamping plate 213 to clamp the machine body vertically up and down, so that the machine body can be stably clamped during the grinding process through the clamping of the other two first clamping plates 213, and at the same time, the grinding of the side surfaces of the machine body is not affected.
