摘要： A frame is coupled to a remotely operable service arm (ROSA), and a rotatable carousel, in turn, is carried by the frame to position several tool modules used in a welding operation adjacent to a damaged tube in a tubesheet of a nuclear steam generator. The arm positions an alignment module directly beneath the damaged tube and the module aligns the carousel. The carousel is rotated to sequentially align and register a laser welding module, a cleaning module, and an inspection module with the damaged tube for a welding operation on a lower portion of the damaged tube in the tubesheet area. One embodiment for the alignment module has a pneumatically operated pin which is operator controlled, and which has an increasing diameter from its distal end to obtain a gross to a vernier alignment of the carousel and, thus, a proper alignment for the remaining modules. A further embodiment provides an alignment pin which is automatically computer controlled without operator intervention. Limit switches and grooves are used as a logic checking device for the proper positioning of a respective module in the frame, and a pneumatically operated radial pin holds the module in the frame.

摘要： An apparatus and method for feeding a throughbolt through a bore in a dynamoelectric machine while initially feeding the same towards the end of the bore along a line forming an acute angle with the axis of the bore. The apparatus has a pair of opposed rotatable wheels and a support plate therefore, at least one guide roller spaced from one end of the support plate, and at least one guide roller spaced from the other end of the support plate. A carriage aligns the wheels and the rollers in two spaced parallel planes through which a through-bolt will pass and a reciprocable member on the carriage effects relative movement between the pair of spaced rotatable wheels and the first and second guide rollers, in a direction transverse the parallel planes such that the through-bolt is deflected from the acute angle at which it is being fed and coaxially aligned with the axis of the bore and adapted to be fed therethrough.
