Abstract
A method to automatically align internal splines (20) of a torque converter (16) to mating external splines (18) of a transmission subassembly (14) during the assembly of the torque converter (16) to the transmission subassembly (14). The apparatus includes a robotic end effector assembly (26) coupled to an arm (22) of a robot (24). The end effector assembly (26) includes a counterbalance mechanism, such as spring assemblies (62) and a position sensor (64) that provide for a reduced effective weight of the torque converter (10) to allow the splines to align and detect if the splines are not properly aligned. Upon sensing non-engagement, robot (24) lifts, rotates and lowers the torque converter (16) until the position sensor (64) detects alignment of the mating splines.
