BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 is a schematic view of the present application.

[0013] Figure 2 is Figure 1 is a partial enlarged schematic view. DETAILED DESCRIPTION

[0014] Referring to the drawings Figures 1-2 The application discloses a ceramic ball anti-blocking type grinding device capable of improving grinding precision, which comprises an upper grinding plate 1, a lower grinding plate 2, an inner ring sleeve 3 and an outer ring sleeve 4, wherein a ring-shaped step 11 is arranged at the lower end of the upper grinding plate 1, the inner ring sleeve 3 is fixedly sleeved in the ring-shaped step 11, the outer ring sleeve 4 is sleeved outside the inner ring sleeve 3 and also located in the ring-shaped step 11, and the upper end of the outer ring sleeve 4 is connected with the upper grinding plate 1; the upper grinding plate 1 is located above the lower grinding plate 2, a ring-shaped groove 21 is designed on the upper surface of the lower grinding plate 2, and the inner ring sleeve 3 is designed as a plastic ring sleeve.

[0015] The plastic ring sleeve is a polyurethane ring sleeve.

[0016] The outer ring sleeve 4 is a steel ring sleeve.

[0017] A plurality of threaded holes 41 are formed in a periphery of the outer ring sleeve 4, screws 42 are rotatably installed in the threaded holes 41, and the bottom portions of the screws 42 are pressed against the outer side of the inner ring sleeve 3.

[0018] The upper end of the outer ring sleeve 4 is connected with the upper grinding plate 1 through multi-point welding.

[0019] A plurality of ceramic balls 5 are placed in the ring-shaped groove 21 of the lower grinding plate 2, the height of the ceramic balls 5 is higher than the depth of the ring-shaped groove 21, the upper grinding plate 1 is pressed on the ceramic balls 5, the lower end of the inner ring sleeve 3 protrudes from the lower end of the upper grinding plate 1 by a length, and the length of the inner ring sleeve 3 is clamped and blocked on the inner side edge of the upper end of the ring-shaped groove 21; the upper grinding plate 1 and the lower grinding plate 2 are relatively rotatably matched.
