如图所示的装置是西德的一项专利,为了可靠而无干涉地夹紧或松开带锥形尾柄的刀杆b,在机床主轴a中装有一根轴向可以移动的拉紧杆c,带勾子g的夹紧爪e被装在拉紧杆c上,夹紧爪可以绕销钉摆动,而勾子g则嵌合在刀杆b的环形槽f中。为了夹紧或松开刀杆b,在夹紧爪e上作出凸台h,凸台h和主轴通孔中的挡块i相配合而进行工作。挡块i上的锁紧面k控制夹紧爪e,而使之处于夹紧位置或者松开位置。
The device shown in the figure is a West German patent which clamps or releases the shank taper taper shank b for reliable and interference-free mounting, with an axially displaceable tensioning The rod c, clamping jaws e with hook g are mounted on the tensioning rod c, the clamping jaws can be pivoted about the pin, while the hook g fits in the annular groove f of the arbor b. In order to clamp or release the cutter bar b, a boss h is formed on the clamping claw e, and the boss h and the stopper i in the through hole of the spindle work together. The locking surface k on the stop i controls the clamping jaws e to be in the clamping or release position.
