Grinding machine for bearing rings and method for moving a bearing ring in such a machine

摘要

This grinding (2) machine for bearing rings (500) includes a frame (4), a rotating grinding wheel (6) movable in rotation around a first rotation axis (X6), a working station (14) where a bearing ring (500) stands during a grinding operation (R6) of one of its surfaces. This grinding machine also includes holding means for holding a bearing ring in the working station and transfer means (100, 200) for transferring bearing rings (500) to and from the working station (14). The transfer means include at least a multi-axis robot (100) and a ring moving arm (200) provided with gripping means for temporarily gripping a bearing ring, this ring moving arm being rotatable around a second rotation axis (X200), parallel to the first rotation axis (X6), and movable in translation along this second rotation axis.
