Grindstone for tire inspection machine, has lock assembly which selectively combines supporting structure with frame when supporting structure exists in actuated position

摘要

A frame (F) has a central shaft for receiving a tire (T) to be tested. A grinder adjoins a supporting structure (12) which is pivotably mounted on the frame. A lock assembly selectively combines the supporting structure with the frame when the supporting structure is in actuated position. A grinding head (30) supported on the edge of the supporting structure, has motors (35,35') connected with the grindstones (32,34). An Independent claim is included for inclination adjuster.
