    • PURPOSE:To facilitate the automatic supply of works by providing a gap between a fixed piece and a movable one into which a locating pin can be inserted, and a drive source disposed separately from a spindle rotating portion for operating the movable piece. CONSTITUTION:A head 7 can be slided forward and backward by a guide shaft 8 supported by an arm 6, and a work locating pin 12 projects from the head 7. A fixed piece 13 of a reference for locating the work is fixed to the end face of a chuck body, and a movable piece 18 is provided opposed to the fixed piece 13 to guide and correct the pin 12. The movable piece 18 can pivot about a fulcrum pin 19 and is urged against a stopper pin 21 by a compression spring 20. The work is inserted into a chuck claw 14. The end of this pin 12 is inserted between the fixed piece 13 and the movable piece 18 and then holding claws 9 are opened to advance a correcting cylinder 22 and urge the pin against the fixed piece 13 for correcting the direction.
    • 目的:通过在定位销可插入的固定件与可移动件之间提供间隙,以及与用于操作可动件的主轴转动部分分开设置的驱动源来促进工件的自动供应。 构成:头部7可以通过由臂6支撑的引导轴8向前和向后滑动,并且工作定位销12从头部7突出。用于定位工件的参考的固定件13固定到端部 卡盘体的表面,与固定片13相对设置的可动片18,以引导和校正销12.可移动片18可绕支点销19枢转,并通过压缩弹簧 将工件插入卡盘爪14中。该销12的端部插入在固定件13和可动件18之间,然后打开保持爪9以使校正缸22前进并且将销推向固定件 件13用于校正方向。
