[0020] The working principle of this utility model is as follows: During use, the painted automotive parts are fixed on the worktable on one side of the support base 1 using tooling fixtures to ensure the stability of the parts. Initial position adjustment: According to the polishing area of ​​the parts, manually push the slide plate 3 to slide back and forth along the track 1 2 to adjust the polishing mechanism as a whole to the initial position close to the parts; start the motor 3 22, the motor 3 22 drives the driven wheel 23 to rotate through the connecting belt 24, and then drives the lead screw assembly 2 to rotate. The front plate 7 slides left and right along the track 2 5 with the slide block 6 to adjust the polishing wheel 12 to the left and right corresponding positions of the polishing area. Start motor 21, which drives driven wheel 16 to rotate via transmission belt 17. Vertical shaft 14 rotates stably under the support of bearing housing 11 and bearing housing 25, and polishing wheel 12 rotates synchronously. Start motor 20, which drives drive wheel 19 to rotate, which drives driven wheel 18 and shaft to rotate via transmission belt. Lead screw assembly 1 rotates, and slider 9 moves slowly up and down along track 3 8. Polishing wheel 12 polishes the sprayed surface of parts evenly. During polishing, dust cover 13 prevents dust from spreading. Operators can observe the polishing situation through transparent dust cover 13 and adjust the speed of each motor and the moving speed as needed. If multiple areas of the parts need to be polished, repeat steps 2-3. By adjusting the front and back position of the slide plate 3, the left and right position of the front plate 7, and the up and down position of the slider 9, the polishing wheel 12 can achieve precise polishing of different areas of the parts. After polishing is complete, turn off motor 1 (20), motor 2 (21), and motor 3 (22) in sequence, push slide 3 away from the workpiece, and remove the polished parts.
