SOCKET FOR UN-TIGHTENING MEMBER TO BE TIGHTENED, AND UN-TIGHTENING MACHINE FOR MEMBER TO BE TIGHTENED
To provide a socket for un-tightening a member to be tightened and an un-tightening machine for a member to be tightened capable of tightening the member to be tightened with high working efficiency even under a working environment in which other members that could hinder tightening work are installed in the vicinity of the member to be tightened.SOLUTION: A socket for un-tightening 30 is used for an un-tightening machine for a member to be tightened including a tightening tool and support means. The support means supports the tightening tool so that a rotation axis of the tightening tool is movable. The socket for un-tightening includes a shaft-like socket body, a movable body, a recessed guide part, and first energizing means. The movable body is supported by the socket body movably between an initial position at the start of tightening and a retracted position. The guide part is formed on the lower surface of the flange part of the movable body eccentrically with respect to the rotation axis, is in sliding contact with a fitted part B1, and guides the tightening tool to a fitting position where the fitting part is fitted to the fitted part B1. The first energizing means energizes the movable body downward.SELECTED DRAWING: Figure 1
【課題】被締付部材の近傍に締付作業の障害となり得る他部材が設置される作業環境下においても、高い作業効率で被締付部材を締付けできる被締付部材の緊解用ソケット、及び被締付部材の緊解機を提供する。【解決手段】緊解用ソケット３０は、締付工具、及び支持手段を具備する被締付部材の緊解機に使用される。支持手段は、締付工具の回転軸心を移動可能に、締付工具を支持する。緊解用ソケットは、軸状のソケット本体と、可動体と、凹状の誘導部と、第１付勢手段とを具備する。可動体は、締付開始時の初期位置と後退位置との間で移動可能にソケット本体に支持される。誘導部は、可動体のフランジ部の下面に、回転軸心に対し偏心形成され、被嵌合部Ｂ１と摺接し、嵌合部が被嵌合部Ｂ１と嵌合する嵌合位置に締付工具を誘導する。第１付勢手段は、可動体を下方に付勢する。【選択図】図１
