Description

Technical Field

[0004] However, the above-mentioned device drives the arc-shaped pressure plate through the adjustment plate to squeeze and fix the bearing ring on the inner wall of the bearing ring, but fixes the bearing ring in the form of internal expansion, and then uses a grinding device to grind the outer circle of the bearing ring.

The arc-shaped pressure plate of the above-mentioned device can only expand and clamp the inner wall of the bearing ring, but cannot clamp the outer circle surface. Therefore, the inner circle surface of the bearing ring cannot be ground. Utility Model Content
