ARRANGE DEVICE OF CONNECTING HOLES

摘要

PURPOSE: A fastener aligning device is provided to reduce a screwing time since the central axes of the fasteners of coupling members are aligned rapidly and stably. CONSTITUTION: A fastener aligning device(100) comprises a rotatable shaft(110), a nut(120), a plurality of aligning bars(140), an elastic ring(160), a guide block(130), and a coupling nut(150). The nut is coupled to one end of the shaft and moves along the central axis of the shaft. The aligning bars are spread in a radial direction of the shaft according to the movement of the nut. The elastic ring is arranged outside the aligning bars and fastening force is applied to the elastic ring by the aligning bars. For the aligning bars to move in a radial direction of the shaft, the guide block guides the aligning bars through a groove(132).
