[0035] Before polishing the external circle of workpiece, the workpiece is arranged in grinding cover 5 and located between the two top pins 10, then rotating block 13 drives double-threaded rod 7 to rotate, at this time, the two moving plates 8 drive support cylinder 9 and top pin 10 to move, so that the two top pins 10 are clamped on the outside of the workpiece, so as to complete the fixation of the workpiece, at this time, the external circle of the workpiece is in contact with the outer wall of contour grinding abrasive belt 4, then driving motor 12 is started, so that driving pulley 12 rotates and cooperates with multiple guide wheels 3 to drive contour grinding abrasive belt 4, at this time, contour grinding abrasive belt 4 can be quickly driven and contacted with the outside of the workpiece to complete grinding, and while grinding, top pin 10 can be rotated, so that the workpiece located between the two top pins 10 can rotate, so as to complete the all-round grinding of multiple areas on the outside of the workpiece.

[0036] Embodiment 2

[0037] In order to enable the workpiece to rotate and be fully ground during grinding process, embodiment 2 is based on embodiment 1, as shown in Figures 3-4 Rotary grinding mechanism for driving top pin 10 to rotate is arranged between support cylinder 9 and top pin 10, rotary grinding mechanism includes worm gear 14 and worm 15, worm gear 14 is fixedly sleeved with top pin 10, mounting plate 16 is fixedly arranged on the end of support cylinder 9, worm 15 is rotationally arranged in mounting plate 16 and cooperatively arranged with worm gear 14, knob 17 is fixedly arranged on the top of worm 15, strip-shaped hole is formed in the top of grinding cover 5, and the upper end of worm 15 is slidingly arranged in the strip-shaped hole.

Since the ejector pins 10 on both sides clamp the workpiece at both ends, when one ejector pin 10 rotates, the entire workpiece rotates, ensuring that multiple areas on the outside of the workpiece can contact the contour grinding belt 4 to complete the grinding process.

[0039] Example 3

[0040] Example 3, based on Examples 1-2, aims to fully collect iron filings and debris generated during the grinding process, such as... Figures 2-3 As shown, an exhaust fan 18 is fixedly installed on the outer wall of the grinding hood 5. The air intake of the exhaust fan 18 is connected to a dust suction pipe 19. The dust suction pipe 19 is fixedly installed on the side of the grinding hood 5. The inner wall of the dust suction pipe 19 has an internal thread. A filter screen plate 20 is installed inside the dust suction pipe 19. The outer wall of the filter screen plate 20 has an external thread, which is engaged with the inner thread of the dust suction pipe 19. Two symmetrically arranged operating rods 21 are fixedly installed at the end of the filter screen plate 20 away from the exhaust fan 18.

[0041] During the grinding process, the exhaust fan 18 runs continuously, which can filter the impurities during the grinding process through the filter screen 20 and then suck them into the exhaust fan 18 and discharge them to the outside. Because the impurities are separated by the filter screen 20, the impurities can be collected in a directional manner and cannot be discharged to the outside. When the grinding work is completed, the filter screen 20 is rotated out of the dust suction pipe 19 by operating the lever 21. At this time, the impurities on the surface of the filter screen 21 can be cleaned and reinstalled before subsequent grinding work can be carried out, ensuring that the surrounding processing environment is not affected during the grinding process.
