A second grinding disc 409 is provided on one side of the first grinding disc 408 at the bottom end of the mounting shell 403. The first grinding disc 408 forms a rotating structure with the mounting shell 403 through the worm gear 406 and the driving rod 407. The worm gear 406 is meshedly connected with the worm 405. The outer wall of the lifting rod 402 is slidably connected to a support frame 5, and a limiting groove 6 is provided inside the support frame 5 at the position corresponding to the lifting rod 402.

[0028] By adopting the above technical solution, the motor 404 is adjusted to drive the worm 405 so that the worm wheel 406 drives the driving rod 407 to rotate, so that the first grinding disc 408 and the second grinding disc 409 rotate, and the mounting shell 403 is moved toward the rotating plate 2 through the lifting rod 402 until it touches the corresponding two groups of parts for processing, thereby improving the efficiency of the processing of the two groups of parts. At the same time, after the processing is completed, the corresponding motor of the rotating plate 2 is driven to rotate, so that the parts are replaced and the brush and sandpaper grinding processes are carried out in turn, thereby improving the completeness of the grinding, avoiding multiple adjustments to improve the efficiency, and driving the connecting block 401 through the sliding device 3, so that the mounting shell 403 drives the first grinding disc 408 and the second grinding disc 409 to slide back and forth to improve the completeness and comprehensiveness of the grinding. When the lifting rod 402 slides, it slides inside the support frame 5 through the limiting groove 6 to improve the stability of the sliding process.

[0029] Specifically, Figure 2 and Figure 4As shown, a cleaning mechanism 7 is arranged between the two lifting rods 402 at the top of the mounting shell 403, and the cleaning mechanism 7 includes a storage shell 701, which is arranged on one side of the lifting rod 402 above the mounting shell 403, and a circulation shell 702 is arranged on one side of the storage shell 701, and a dust collection device 703 is embedded between the storage shell 701 and the circulation shell 702.

The worm 405 is driven by the adjusting motor 404, and the corresponding driving rod 407 is driven to rotate through two worm gears 406, so that the first grinding disc 408 and the second grinding disc 409 are polished. A brush is set on the outer wall of the first grinding disc 408, and the second grinding disc 409 is sandpaper. During the first grinding, the parts are placed under the first grinding disc 408, and the second grinding disc 409 is idle.

According to the order of grinding with a brush first and then with sandpaper, the support frame 5 is fixed to the inner wall of the processing machine tool 1, and the grinding mechanism 4 is limited by the support frame 5 and the limit groove 6 to keep the lateral movement of the grinding mechanism 4 stable.
