Abstract: An automatic electrohydraulic chamfering unit, which can be operated with a conveyor means or incorporated into an automated gear-generating machine, comprises upper and lower centering and clamping assemblies for retaining a workpiece therebetween, upper and lower chamfering assemblies for chamfering the tooth edges at the toe and heel of each tooth, an indexing assembly for successively aligning each tooth of the workpiece with the chamfering tools and an automatic control system which governs the operating sequence of the above components during the chamfering cycle. The upper and lower centering and clamping assemblies are actuated by the control system to permit rotational movement of a workpiece during the indexing portion of the chamfering cycle and to firmly lock a workpiece in a fixed position during the chamfering portion of the cycle. The upper and lower chamfering assemblies are mounted on the chamfering unit so that the chamfering assemblies can be independently adjusted relative to the centering and clamping assemblies along the three major axes and about one of the axes for locating the chamfering assemblies relative to the workpiece. The indexing assembly through the reciprocating movement of a spring-biased finger which is received between the workpiece teeth indexes a workpiece by movement of the finger parallel to the axis of rotation of the workpiece. Scales are provided on the indexing assembly, the chamfering assemblies and mountings to facilitate initial and subsequent adjustments of the various components of the chamfering unit.
