A toolholder for a numerically controlled machine is engaged by bars 7 in notches 9 and recess 10 of a bracket 5. The bracket bears a four-hooked mounting saddle and a pivotable abutment 16, and can be engaged with a slotted mounting plate 1 by: (a) first engaging the upper hooks, then swinging the bracket downwardly until the lower hooks engage, and the abutment contacts the plate at 15 (b) first folding the abutment upwardly, thereby allowing the lower hook to engage first, then swinging the bracket upwardly to engage the upper hooks, and finally swinging the abutment down to contact the plate at 15. Method (a) is used when the vertical spacing of slots 2 is large, and method (b) is used when the slots are closely spaced. The inclination of the toolholder can be selected according to which notch 9 is used. <IMAGE> |
