MOVABLE PART ASSEMBLING METHOD AND DEVICE THEREFOR

PURPOSE:To make it possible to shorten the cycle time of an automated assembly line, by feeding a workpiece onto the assembly line in such a condition that loading rings are temporarily fixed to the workpiece by locating pins. CONSTITUTION:Locating pins 23 fed from a part feeder 22 are fed under pressure from a pressure feed pipe 34 in an automatic locating pin inserting device 34 through a guide pipe 28. Then, the locating pins 23 are inserted in a workpiece on an index unit 26 and locating holes 35 in loading rings 1, 2, and therefore, the loading rings 1, 2 are temporarily fixed to the workpiece by means of the locating pins 23. Then, the workpiece is fed onto a base conveyer in an assembly line by way of a workpiece mounting station 36. Further, gears adapted to be meshed with tooth sections 10, 11 in the loading rings 1, 2 which are temporarily secured to the workpiece, are mounted on the workpiece from several working stations 37 in association with the movement of the base conveyer in the assembly line.
