The slider 419 is fixedly connected with the clamping block 420, and the upper end of the slider 419 is respectively provided with a second guide groove 422, and the interior of the second guide groove 422 is clamped and installed with a connecting frame 425, and the two ends of the lower surface of the connecting frame 425 are respectively fixedly installed with positioning rods 424, and the two ends of the upper surface of the rotating table 405 are respectively provided with a plurality of positioning holes 423, and the lower end of the positioning rod 424 is clamped and installed in the interior of the positioning hole 423, and the lower end of the rotating table 405 is fixedly installed with a rotating ring 406, and the inner lower surface of the processing box 1 is provided with a groove 408, and the rotating ring 406 is movably installed. Inside the groove 408, the rotating ring 406 is located on the outer side of one end of the groove 408 and is fixedly installed with a first gear 407. A movable groove 410 is provided at one end of the interior of the processing box 1. A second gear 411 is movably installed inside the movable groove 410. The second gear 411 is meshed with the first gear 407. A motor 412 is installed at the lower end of the movable groove 410. The output end of the motor 412 is connected to the second gear 411. A limit ring 409 is installed on the lower surface of the rotating table 405. The limit ring 409 is snap-fitted and installed on the processing box 1. At the inner lower end, a first guide groove 413 is provided at the inner lower end of the processing box 1, and the first guide groove 413 and the raw material 3 are parallel to each other in the upper and lower directions. A recovery pipe 414 is installed through the lower end of the first guide groove 413, and a storage box 415 is installed at the lower end of the processing box 1. The lower end of the recovery pipe 414 is connected to the storage box 415, and an exhaust hole 417 is penetrated on one side of the storage box 415. A suction fan 416 is installed on the outer side of the storage box 415, and the suction fan 416 is connected to the exhaust hole 417, and a filter screen 418 is installed inside the exhaust hole 417.

[0024] The user places the raw material 3 on the upper end of the rotating table 405, and allows the lower end of the raw material 3 to be located inside the rotating table 405, so that when the inside of the raw material 3 is sandblasted and polished, sand will not splash or leak out between the raw material 3 and the rotating table 405. Then, after the raw material 3 is placed, the user can push the slider 419 to allow the slider 419 to drive the clamping block 420 to move along the slide groove 421, so that the clamping block 420 clamps and positions the raw material 3, so that the raw material 3 and the clamping block 420 fit tightly. Then, the user inserts the connecting frame 425 into the second guide groove 422 to connect the connecting frame 425 and the slider 419. Then, as the connecting frame 425 moves downward, the connecting frame 425 drives the positioning rod 424 to insert into the positioning hole 423 to realize the positioning of the slider 419, so that the slider 419 drives the clamping block 420 to clamp and position the raw material 3 more stably.

[0025] Then, after the raw material 3 is placed, the electric push rod 401 will drive the temporary storage box 402 and the nozzle 403 to move downward, and then after the nozzle 403 enters the upper end of the raw material 3, the external sand bin can input the sand into the temporary storage box 402 along the transport pipe 404, and then the sand in the temporary storage box 402 can be sandblasted and polished through the nozzle 403;

[0026] When the raw material 3 is sandblasted, the motor 412 drives the second gear 411 to rotate, and then the second gear 411 is meshed with the first gear 407, thereby driving the rotating table 405 and the rotating ring 406 to rotate slowly inside the groove 408, so that the rotating table 405 can drive the raw material 3 to rotate through the clamping block 420, so as to cooperate with the nozzle 403 to perform all-round grinding on the inside of the raw material 3, which is faster;

[0027] The limiting ring 409 is used to isolate the rotating table 405 from the inside of the processing box 1, which can not only assist the rotating table 405 in rotating, but also prevent sand from being blocked between the rotating table 405 and the processing box 1, causing the rotating table 405 to be unable to work normally;

[0028] Then, when the raw material 3 is sandblasted and polished, the suction fan 416 will suck and discharge the air in the storage box 415 through the exhaust hole 417, so that the storage box 415 can suck the air in the processing box 1 through the recovery pipe 414, so as to achieve the suction of sand and dust when the raw material 3 is sandblasted and polished, so that the sand and dust can be blown by the air along the first guide groove 413 and the recovery pipe 414 into the interior of the storage box 415, so as to achieve the recovery of sand and recycle the sand. At the same time, the filter screen 418 will filter the filter screen 418 in the air to avoid the recovery from leaking to the outside along the exhaust hole 417 and the suction fan 416 to cause pollution, so as to better protect the environment.

[0029] The working principle of this grinding device for automobile parts processing:

[0030] When in use, the user first places the raw material 3 on the upper end of the rotating table 405, and allows the lower end of the raw material 3 to be located inside the rotating table 405. Then, after the raw material 3 is placed, the user can push the slider 419 to allow the slider 419 to drive the clamping block 420 to move along the slide groove 421, so that the clamping block 420 clamps and positions the raw material 3, and the raw material 3 and the clamping block 420 fit tightly. Then, the user inserts the connecting frame 425 into the second guide groove 422 to connect the connecting frame 425 and the slider 419. Then, as the connecting frame 425 moves downward, the connecting frame 425 drives the positioning rod 424 to insert into the positioning hole 423 to realize the positioning of the slider 419. Then, after the raw material 3 is placed, the electric push rod 401 will drive the temporary storage box 402 and the nozzle 403. The raw material 3 is moved downward, and then after the nozzle 403 enters the upper end of the interior of the raw material 3, the external sand bin can input the sand into the temporary storage box 402 along the transport pipe 404, and then the sand entering the temporary storage box 402 can be sandblasted and polished through the nozzle 403. At the same time, when the raw material 3 is sandblasted and polished, the motor 412 drives the second gear 411 to rotate, and then the second gear 411 is connected to the first gear 407 through meshing, thereby driving the rotating table 405 and the rotating ring 406 to rotate slowly inside the groove 408, so that the rotating table 405 can drive the raw material 3 to rotate through the clamping block 420, thereby driving the nozzle 403 to move up and down through the electric push rod 401, and the rotating table 405 drives the raw material 3 to rotate, so as to realize the polishing of various positions inside the raw material 3;

[0031] At the same time, when the raw material 3 is sandblasted and polished, the suction fan 416 will suck and discharge the air in the storage box 415 through the exhaust hole 417, so that the storage box 415 can suck the air in the processing box 1 through the recovery pipe 414, so as to achieve the suction of sand and dust when the raw material 3 is sandblasted and polished, so that the sand and dust can be blown by the air along the first guide groove 413 and the recovery pipe 414 into the interior of the storage box 415, so as to realize the recovery of sand.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
