Abstract
PURPOSE: To position a rack bar accurately and to facilitate attaching and detaching of a mandrel by providing a clamping device for rack bar which prevents the push back of the rack bar to the retreat end of the rack bar.
CONSTITUTION: When a rack 21 and a rack bar 9 are moved to the retreat limit by a pinion, a press roller 23 is moved in a direction G by a cylinder via a lever, until it abuts on the end face of the bar 9, when the bar 9 stops. On the other hand, a roller 28 moves in direction H, and depresses a link 29. The link 29 moves around a fulcrum 31 in a direction K, and clamps a block 34 mounted to the bar 9 by means of a clamping head 30. Thereby, the generation of springback during stoppage of the rack bar is prevented, the rack bar is positioned accurately, and the attaching and dtaching of the rack bar 9 and the mandrel are made possible.
