ARRANGE DEVICE OF CONNECTING HOLES

摘要

PURPOSE: A joining hole aligning device is provided to stably align positions of joining holes of materials, thereby reducing time required for thread-combining. CONSTITUTION: A joining hole aligning device(100) comprises a shaft(110), a nut, aligning bars(140), a guide block(130), and a joining nut(120). The nut is joined to an end portion of the shaft and moves along a center axis. The plurality of aligning bars comprises spring fixing units(144a,144b) and a guide moving unit(146). A spring is joined to the spring fixing unit. The guide block comprises spring fixing projections(134a,134b) and a linear guide(132). The linear guide guides the linear movement of a guide moving unit. The guide block guides the aligning bars to a radial direction of the shaft. The joining nut is arranged in one end portion of the guide block. The spring is joined between the spring fixing projections and spring fixing units. The joining nut is arranged in one end portion of the guide block and the shaft passes through an opening of the joining nut.
