PROBLEM TO BE SOLVED: To instantly respond and prevent slipping down when a workpiece set in a horizontal hanging intact clamp is slipped down by a certain amount during lifting transport.SOLUTION: A horizontal hanging intact clamp includes: a stopper cam 24 rotatably provided in a camming pin 23, separately and independently from a presser cam; a slip detection lever 36 having an engagement part 36a, at one end, capable of abutting on a tip upper surface Wa of a workpiece W inserted into an opening, and having the other end rotatably connected with a clamp body 11; a pull spring 34 for biasing the engaging teeth 25 of the stopper cam in the direction of projecting toward an opening; and an operation link 35 for rotating the stopper cam in a predetermined direction when a slip detection lever is rotated in a predetermined direction, to make the engaging teeth project toward the opening by the tension of the pull spring 34. When the engagement part of the slip detection lever is separated from the workpiece tip upper surface, the engaging teeth of the stopper cam project toward the opening and bite into the workpiece tip upper surface, thus preventing the slipping down of the workpiece.
【課題】横吊り用無傷クランプにセットしたワークが吊り上げ運搬中に一定量ずり落ちたときに瞬時に応答して滑落防止する。【解決手段】押さえカムとは別個独立にカムピン23に回転可能に設けられるストッパーカム24と、開口に挿入されたワークWの先端上面Waに当接可能な係合部36aを一端に有すると共に他端がクランプ本体11に回転自在に連結される滑り検知レバー36と、ストッパーカムの係合歯25が開口に向けて突出させる方向に付勢する引きバネ34と、滑り検知レバーが所定方向に回転したときに引きバネ34の張力でストッパーカムを所定方向に回転させて係合歯を開口に向けて突出させる作動リンク35とを備える横吊り用無傷クランプである。滑り検知レバーの係合部がワーク先端上面から離れると、ストッパーカムの係合歯が開口に向けて突出してワーク先端上面に喰い込み、ワークの滑落を防止する。【選択図】図12
