[0036] The sand blasting nozzle 45 is disposed above the clamping cylinder 1 31 and the clamping cylinder 2 32 , so that the workpiece can be turned over by adjusting the lateral angle of the sand blasting nozzle 45 in coordination with the clamping cylinder 1 31 and the clamping cylinder 2 32 , so as to improve the comprehensiveness of the workpiece polishing.

[0037] The present invention provides a device and method for pre-blasting and polishing of grinding flow processing, the steps of which include: S1. The workpiece is clamped between the clamping cylinder 31 and the clamping plate 37 inside the clamping cylinder 32; S2. Polishing the workpiece surface by extracting the material in the material box 46 with the air supply mechanism 47 to supply air from the bottom of the sandblasting nozzle 45; S3.

The material passes through the screen frame 64 and the screen frame 65 and falls into the recovery frame 68 for collection; S5. The foreign matter is blocked by the screen frame 1 64 and the screen frame 2 65 and is vibrated by the vibration motor 67 and moves toward the waste outlet 7 to be discharged from the outside of the recovery box 2.

[0038] The working principle of the grinding flow processing pre-sandblasting and polishing device is described in detail below.

[0039] like Figures 1 to 6 As shown, by setting the workpiece between the clamping plates 37 inside the clamping cylinder 1 31 and the clamping cylinder 2 32, and driving the clamping cylinder 1 31 and the clamping cylinder 2 32 to move inward through external control, the workpiece is clamped and fixed by the clamping plate 37 against the side of the workpiece, by closing the front door panel of the polishing box 1, the material is sent into the sand blasting nozzle 45 through the pipeline by controlling the pump at the bottom of the material box 46, and air is pumped into the sand blasting nozzle 45 through the air supply mechanism 47, and the material is ejected from the sand blasting nozzle 45 by compressed air, so that the high-speed moving abrasive material flushes the surface of the workpiece for polishing, and the servo motor 1 35 inside the shield 33 is controlled to drive the clamping plate 37 inside it to rotate, thereby driving the clamping plate 37 inside the bearing sleeve 36 to rotate to rotate the workpiece, and at the same time, the movable block 42 is driven to rotate by the servo motor 2 43 to drive the extension The retractable cylinder 44 and the sand-blowing nozzle 45 rotate laterally and the distance between the sand-blowing nozzle 45 and the workpiece is changed by the telescopic cover of the telescopic cylinder 44, so as to change the polishing position, so as to flexibly polish the workpiece comprehensively. After the material falls into the polishing box 1, it is collected toward the recovery port 5 and carries the foreign matter into the recovery box 2. The material falls onto the screen frame 1 64 above the recovery box 2. The vibration motor 67 on the inner side of the mounting seat 2 66 drives the screen frame 1 64 and the screen frame 2 65 to vibrate up and down, so that the material falling onto the screen frame 1 64 vibrates at a high frequency. After the material passes through the screen frame 1 64, it falls onto the screen frame 2 65. Through the double-layer setting, the foreign matter in the material is filtered. The material passes through the screen frame 2 65 and falls into the recovery frame 68 for collection. The foreign matter is blocked on the screen frame 1 64 and the screen frame 2 65, and rolls along the screen frame 1 64 and the screen frame 2 65 toward the waste outlet 7 with the vibration and is discharged from the waste outlet 7.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
