PURPOSE: To make it possible to assemble various kinds of electronic parts with the use of only one assembling device, by providing such an arrangement that an electronic part is aligned with a bolt fastening position while leaving a torque motor section stationary, and spline shafts are connected between universal joints to freely move the nut sections of the spline shafts.
CONSTITUTION: Each set of flexible joints 8 which are secured respectively to a chuck section 17 and a constant torque motor section 6, are connected together by means of a spline shaft 10 and a spline housing 9. When a positioning guide section 14 is raised so that a tapered section 20 is aligned with the tapered section of a jig 4, and therefore, an electronic part is positioned at the center of the device. The position of each bolt 3 for the electronic part is detected by a sensor delivering a position signal by which a drive motor 12 in a movable section 16 is driven in association with constant pulses so that the chuck section 17 moves a side guide 11 to be aligned with the bolt 3, and the electronic part is raised by means of a guide 14 so that the bolt 3 is engaged with the chuck section 17 to be stopped by a stopper 18, thereby the bolt 3 may be fastened by a motor 6.
