Belt grinding assembly.

摘要

A belt grinding assembly (10) for grinding an object. An object manipulating mechanism moves an edge surface (14) of the object at a uniform rate of speed along a path relative to a first direction in which an abrasive belt (17) is driven into forceful engagement with the abrasive belt (17) as it is driven along a contact wheel. The object manipulating mechanism includes a wheel (28) rotated at a uniform speed about an axis at a right angle to the first direction to sequentially move the periphery of the wheel (28) past a loading station and then past the contact wheel; a clamp including jaws (35, 36) mounted on the wheel (28) for relative movement between a release position with the jaws (35, 36) spaced to freely receive an object, and an engage position adapted to firmly clamp the object between the jaws (35, 36); and jaw actuating structure that moves the jaws (35, 36) from a release position at the loading station, and positions the jaws (35, 36) in the engage position during movement of the clamp assembly past the support surface (23). <IMAGE>
