ABSTRACT:
An assembly machine is provided having an actuator which transmits power from a driver reciprocating along a first axis to appropriate assembly machine tooling wherein spring loaded overload protection can be provided for all movement of the output shaft of the actuator. Overload protection in either or neither direction of movement of the actuator can be provided. The disclosed actuator can be used on an assembly machine having a rotatable assembly table which moves in indexed steps around a main center support column. A tooling mount is provided for supporting various tooling which performs operations on devices to be assembled which are mounted on the rotatable assembly table. A reciprocating drive is provided around the main center support column. The disclosed actuator is utilized to transmit power from the reciprocating driver to appropriate tooling. The actuator comprises a first lever which engages the driver and a second lever which is clamped to the first lever by a spring clamp assembly for unison movement therewith. The first and second levers are pivotally supported for movement around a common pivot point. As long as the second lever does not encounter a force greater than the compression force of the spring clamping member, the first and second levers move together. If an overload greater than the predetermined force is encountered, a spring in the spring clamping assembly is compressed and the first and second levers move independently. The spring clamping assembly is constructed so that the spring member is compressed when the second lever encounters an overload obstacle while moving in either direction.
