  • Sequential loading apparatus
    Patent number: 6666119
    Abstract: An apparatus for sequential loading, by means of a pusher, of bars in a rotating spindle of a machine tool, this loading apparatus comprising a device for alignment of an end of each loaded bar, on the axis of the spindle of the machine tool, the said alignment device itself comprising jaws which, having bearing surfaces able to define a cylindrical support around the bar, are supported by a mechanism allowing their counter-displacements, wherein said mechanism for displacement of the jaws of the apparatus includes: a drive element, a device for control of this drive element, and this as a function of at least one of the parameters which are: the diameter of the bar to be loaded in the machine tool, the diameter of the pusher in a part capable of being engaged in the jaws, the surpassing of a predetermined threshold for vibrations in the bar.

  • Feeder of short rods for a machine tool
    Patent number: 6272955
    Abstract: The feeder for short rods of a diameter of between 6 and 120 mm for a machine such as a turning lathe or an automatic lathe comprises a rod loading device having elements for holding a plurality of rods on an inclined plane and loading slides, a device for centering rods along an axis of alignment with respect to the machine tool, and a device for advancing rods in the machine tool. The holding elements are fingers which do not just hold a rod, but offer it, in the course of loading, a support surface in such a way that the rod is simultaneously supported by the finger and the loading slide. The feeder further comprises a device making it possible to adapt the position of the first rod to be loaded to the diameter of this rod when the limit stop for the course of the loading slide is adjusted to the diameter of the rod.
