Clamping chuck for clamping part to be machined on Schaublin 102 lathe, has jaws engaged with flange so as to be moved toward or away from each other based on axial position of flange, where each jaw is mounted on base plate

摘要

The chuck has a set of planet gears (3) engaged with a tie rod (2) of a machine tool, so that axial displacement of the tie rod produces radial displacement of the gears by sliding on inclined planes (25, 26) of the gears. A flange (22) includes an inclined flank engaged with inclined flanks of the planet gears, so that radial displacement of the gears produces axial displacement of the flange. A set of jaws (11) is engaged with the flange so as to be moved toward or away from each other based on the axial position of the flange, where each jaw is mounted on a base plate (6).
