Abstract

A device for catching cut off workpieces from a C. N. C. lathe, the lathe having a toolholding turret and a turret back wall. The device attaches to the turret. A basket for catching cut off workpieces is attached to a bracket. The bracket is shaped to be attachable to the turret, to permit the basket to fit underneath the workpiece and to permit the basket to clear the turret back wall when the turret is rotated about its axis into any position. Preferably, an L-shaped bracket is used for octagon type turrets and an oblique angled bracket is used for VDI turrets. One version of the invention comprises a lathe to which a C. N. C. parts catcher is attached. Another version of the invention is a method for catching workpieces cut off from the spindle of a C. N. C. lathe.

12. A C. N. C. lathe parts catcher for use on a C. N. C. lathe having a toolholding turret and a turret back wall comprising:

a. a basket for catching cut off lathe workpieces, the basket having a sidewall having one or more holes for fastening to a bracket;

b. a bracket having a slot at one end for fastening to the turret and one or more holes at the other end for fastening to the basket, the bracket being shaped to permit the slotted end to be fastened to the turret, being shaped to permit the end of the bracket having the holes to be fastened to the basket, being shaped to permit the bracket and basket position to be adjusted along an axis substantially parallel to the longitudinal axis of the lathe workpiece, being shaped to permit the simultaneous adjustability of the distance between a cutoff tool mounted to the turret and the basket and the distance between the basket and the turret back wall when that distance is minimized by turret rotation along the turret axis by the selection of different combinations of bracket holes and basket holes for fastening the bracket to the basket, being shaped to permit the basket to be positioned underneath the workpiece for catching the finished workpiece when the cutoff tool mounted to the turret is in contact with the workpiece, and being shaped to permit rotation adjustment of the basket about the selected basket hole and bracket hole; and

c. a fastener for attaching the basket to the bracket at a selected basket hole and a selected bracket hole and to fix the rotated position of the basket about the selected basket hole and bracket hole, inserted through the selected bracket hole and basket hole, thereby securing the basket to the bracket.

13. The C. N. C. lathe parts catcher recited in claim 12, wherein the basket has one sidewall height greater than the height of the remaining basket walls, the higher sidewall containing the one or more holes.
